150726150726
Opfindelsen angår en beholder af termoplastisk materiale, hvilken beholder er beregnet til steril opbevaring af f.eks. væske, pulver, pasta eller lignende materialer og er af den type, der er angivet i krav l's indled-5 ning.The invention relates to a container of thermoplastic material which is intended for sterile storage of e.g. liquid, powder, paste or similar materials and are of the type set forth in the preamble of claim 1.
Ved mange anvendelser er der behov for en beholder, hvor det er nødvendigt, at et i beholderen opbevaret produkt forbliver sterilt, og at risikoen for forurening af produktet, når dette tages ud af beholde-10 ren, reduceres så vidt det er muligt økonomisk, tek nisk og praktisk under hensyn til produktets anvendelse .In many applications, a container is needed where it is necessary that a product stored in the container remains sterile and that the risk of contamination of the product, when taken out of the container, is reduced as far as economically possible. technical and practical, taking into account the use of the product.
Kravet om at produktets sterilitet bevares under dets opbevaring i beholderen medfører, at beholderen efter 15 fyldning og lukning skal danne et lukket og tætnet rum, og at der i de tilfælde, hvor beholderen består af flere dele, skal være en pålidelig og tæt forbindelse mellem disse dele. For at sikre steriliteten af produktet, som opbevares i beholderen, er det na-20 turligvis også nødvendigt, at beholderens indre, i det mindste ved de anvendelser, hvor sterilisering af beholderen, når dennes indhold er påfyldt, ikke kan finde sted, holdes sterilt under hele perioden fra beholderens fremstilling og indtil fyldnings- og luknings-25 operationerne.The requirement that the product's sterility be retained during storage in the container means that after filling and closing, the container must form a closed and sealed compartment and that in cases where the container consists of several parts there must be a reliable and close connection between these parts. In order to ensure the sterility of the product stored in the container, it is of course also necessary that the interior of the container, at least in those applications where sterilization of the container, when its contents are filled, cannot be kept sterile during the entire period from the manufacture of the container up to the filling and closing operations.
For at undgå forurening af produktet, når beholderen tømmes for sit indhold, er det nødvendigt, at beholderens tømningsområde er så rent som muligt, hvilket kræver, at tømningsområdet, når beholderen er blevet 30 fyldt med produktet, kan beskyttes mod forurening under beholderens lukning, opbevaring, transport og åbning. For at sikre tømningsområdets renhed, er det endvidere nødvendigt, at beholderen er nem at åbne, 150726- 2 og at tømningsområdet ikke forurenes f.eks. via kontakt med fingrene ved åbningen. Ved visse anvendelser er det også ønskeligt, at beholderen kan åbnes mekanisk.In order to avoid contamination of the product when the container is emptied of its contents, it is necessary that the emptying area of the container is as clean as possible, which requires that the emptying area, when the container has been filled with the product, can be protected from contamination during the closure of the container, storage, transportation and opening. Furthermore, to ensure the purity of the emptying area, it is necessary that the container is easy to open, and that the emptying area is not contaminated e.g. via contact with the fingers at the opening. In certain applications, it is also desirable that the container may be opened mechanically.
5 Det er endvidere et krav, at når beholderen åbnes, dvs. når det i beholderen opbevarede produkt gøres tilgængeligt til brugeren, skal denne åbning finde sted hurtigt. På den anden side er det generelt accepteret, at forberedelserne til åbningen kan tage 10 en vis tid. Hurtig åbning opnås mest enkelt ved, at beholderen er forsynet med en svækkelseszone, ved hjælp af hvilken den endelige åbning finder sted. En sådan udformning kræver igen, at beholderen kan anbringes således, at materialevæggen i svækkelseszonen ikke er udsat for 15 at blive brudt under håndteringen af beholderen i forbindelse med dens distribution og opbevaring. Selv en lille revne i svækkelseszonens materialevæg kan medføre, at indholdets sterilitet går tabt. For at bevare produktets sterilitet så vidt muligt, når det for-20 lader beholderen, er det også vigtigt, at svækkel seszonen ikke kommer til anlæg mod andre genstande og beskyttes mod kontakt. Forurening af tømningsområdet vil medføre den risiko, at produktet forurenes ved kontakt med området under tømningen af beholderen.Further, it is a requirement that when the container is opened, i. when the product stored in the container is made available to the user, this opening must take place quickly. On the other hand, it is generally accepted that preparations for the opening may take some time. Quick opening is most easily achieved by providing the container with a weakening zone by which the final opening takes place. Such a design, in turn, requires that the container be positioned so that the material wall in the weakening zone is not exposed to being broken during handling of the container in connection with its distribution and storage. Even a small crack in the material wall of the weakening zone can cause the content's sterility to be lost. In order to preserve the sterility of the product as far as possible when leaving the container, it is also important that the weakening zone does not touch other objects and is protected from contact. Contamination of the emptying area will result in the risk that the product will be contaminated by contact with the area during the emptying of the container.
25 Formålet med opfindelsen er at angive en beholder, som tilfredsstiller de nævnte krav. En beholder i-følge opfindelsen muliggør steril opbevaring under lang tid af produkter, såsom væske, pulver, pasta, piller etc. og reducerer risikoen for forurening af 30 produktet ved fjernelsen af beholderens indhold. Be holderen hår en original tætning, som, efter at beholderen er fyldt, beskyttes mod påvirkning udefra, så at den holdes intakt; beholderen har en svækkelseszone, der er beskyttet mod forurening, og er så- 3 150726 ledes indrettet, at indtil fyldningen finder sted, kan den opbevares tom i en forseglet, steril tilstand, og kan lukkes efter fyldningen (og ved visse anvendelser også autoklavsteriliseres), så at dens steri-5 litet bevares, indtil den åbnes (beholderens tætning brydes). Ued udtrykket bevaret sterilitet forstås her både beholderens indhold og den del af beholderen, som danner svækkelseszonen.The object of the invention is to provide a container which satisfies said requirements. A container according to the invention enables long-term sterile storage of products such as liquid, powder, paste, pills, etc. and reduces the risk of contamination of the product upon removal of the contents of the container. Keep the holder hair an original seal which, after filling the container, is protected from outside impact so that it is kept intact; the container has a contaminant protection zone and is so arranged that, until the filling takes place, it can be stored empty in a sealed, sterile state and can be closed after filling (and in some applications also autoclave sterilized) so that its sterility is maintained until it is opened (the seal of the container is broken). Without the term preserved sterility, here is understood both the contents of the container and the portion of the container which forms the weakening zone.
Ifølge opfindelsen er beholderen udformet som angivet 10 i den kendtegnende del af krav 1. Beholderlegemet er altså lukket af et lukkeorgan, der er forbundet med beholderlegemet i en permanent tæt samling, der sikrer effektiv steril tætning, idet lukkeorganet er udformet med en fastgørelsesdel, hvor fikseringen til beholder-15 legemets mundingsdel finder sted. Beskyttelseshætten sikrer de ydre dele af lukkeorganet og beholderens tilstødende dele mod forurening under opbevaring. Lukkeorganets ende, som vender bort fra fastgørelsesdelen, har en aftagelig del, der udformes således, at den let kan 20 fjernes, uden at der sker en kontaminering af indholdet.According to the invention, the container is configured as defined in the characterizing part of claim 1. The container body is thus closed by a closure member connected to the container body in a permanently sealed assembly which ensures effective sterile sealing, the closure member being formed with a fastening member, wherein the fixation to the mouth portion of the container body takes place. The protective cap secures the outer parts of the closure member and the adjacent parts of the container against contamination during storage. The end of the closure member, which faces away from the attachment member, has a removable member which is designed so that it can be easily removed without contamination of the contents.
Den aftagelige del kan ved en foretrukken udførelsesform ydermere være således indrettet, at den ved fjernelsen af et ydre parti danner en midlertidig fyldningsåbning 25 for tilførsel af det gods, som beholderen skal fyldes med. Permanent og tæt lukning af den midlertidige påfyldningsåbning finder derpå sted.Further, in a preferred embodiment, the removable portion may be arranged such that upon removal of an outer portion it forms a temporary filling opening 25 for supplying the goods with which the container is to be filled. Permanent and close closure of the temporary filling port then takes place.
Beskyttelseshætten kan ifølge opfindelsen være udformet med et eller flere tætningslæbeorganer, der er indrettet 30 til at komme til anlæg mod områder af fastgørelsesdelen til tilvejebringelse af tætning mellem fastgørelsesdelen og beskyttelseshætten i monteret stand, idet tætningslæbeorganerne aktiveres, når beskyttelseshætten anbringes omkring beholderens hals. Den originalforseglede behol-35 der er indrettet til at blive åbnet ved svækkelseszonen, 4 150726 hvorved der dannes en tømmeåbning, som er omgivet af fastgørelsesdelen. Beholderen har fortrinsvis også orga-* ner, der er indrettet til at danne en tætning mellem beskyttelseshætten og beholderens halsparti. Ved visse 5 udførelsesformer kan beskyttelseshætten være udformet, så den danner et organ til forskydning af den aftagelige del og således til brydning af lukkeorganet i svækkelses-zonen til åbning af en originalforseglet fyldt beholder.According to the invention, the protective cap can be formed with one or more sealing lip means arranged to abut against areas of the fastening part to provide sealing between the fastening part and the protective cap in mounted condition, the sealing lip means being actuated when the protective cap is placed around the container neck. The original sealed container adapted to be opened at the weakening zone, 4 150726 thereby forming a discharge opening surrounded by the attachment member. Preferably, the container also has means adapted to form a seal between the protective cap and the neck portion of the container. In certain embodiments, the protective cap may be designed to form a means for displacing the removable portion and thus for breaking the closure member in the weakening zone to open an original sealed filled container.
Opfindelsen beskrives nærmere i det følgende under 10 henvisning til tegningen, hvor fig. la og b viser den øvre del af beholderen ifølge en udførelsesform for opfindelsen, udformet med et gevind, og viser den ene halvdel af beholderen i tværsnit, 15 fig. 2 viser den øvre del af en beholder ifølge en udførelsesform for opfindelsen med en snap-funktion og viser den ene halvdel af beholderen i tværsnit, fig. 3a-d viser i tværsnit detaljer af udførelses-former for beholderen i området for fikseringen af 10 et i beholderen indgående lukkeorgan, fig. 4a og b viser i tværsnit alternative udførelses-former for tætningsorganer, der er anbragt på beholderens beskyttelseshætte, og fig. 5 viser den øvre del af en beholder i en ud-25 førelsesform, hvor beskyttelseshætten danner et organ til forskydning af den aftagelige del under beholderens åbning, og viser den ene halvdel af beholderen i tværsnit.The invention will now be described in more detail below with reference to the accompanying drawings, in which: FIG. 1a and b show the upper part of the container according to an embodiment of the invention, configured with a thread, and shows one half of the container in cross-section; 2 shows the upper part of a container according to an embodiment of the invention with a snap function and shows one half of the container in cross section; FIG. 3a-d show in cross-section details of embodiments of the container in the region of the fixation of a closure member included in the container; 4a and b show in cross section alternative embodiments of sealing means arranged on the protective cap of the container; and FIGS. 5 shows the upper part of a container in one embodiment, wherein the protective cap forms a means for displacing the removable part below the opening of the container, and shows one half of the container in cross section.
Fig. la og b viser en udførelsesform for opfindelsen, 5 150726 hvor en beholder med et beholderlegeme 1 er udformet med en beskyttelseshætte 25 (kun vist i fig. Ib). Beskyttelseshætten er udformet med et indvendigt gevind 27, som samvirker med et udvendigt gevind 5 på 5 en del 3 af beholderlegemets 1 hals 2. Halsen er opad- til udformet med et mundingsparti 6, som omgiver beholderlegemets mundingsåbning 7. Mundingspartiet 6 har en indre flade 8 og en derfra udragende, rundt-gående flange 9, som danner en øvre, i hovedsagen 10 plan rundtgående flade 10, der støder op til den indre flade 8. Fladerne 8 og 10 danner således i den viste udførelsesform i tværsnit en i hovedsagen ret vinkel med hinanden. I den viste udførelsesform ligger mundingspartiet 6 nærmere beholderens akse end halsens 15 gevindparti 3 og er også aksialt forskudt fra dette i en retning bort fra beholderlegemet 1.FIG. 1a and b show an embodiment of the invention, wherein a container with a container body 1 is provided with a protective cap 25 (only shown in Fig. 1b). The protective cap is formed with an inner thread 27 which cooperates with an outer thread 5 of 5 a part 3 of the neck body of the container body 2. The neck is upwardly formed with an orifice portion 6 which surrounds the mouth opening of the container body 7. The mouth portion 6 has an inner surface. 8 and a circumferential flange 9 extending therefrom forming an upper, generally flat plane 10 surface adjacent to the inner surface 8. Thus, in the illustrated embodiment, the surfaces 8 and 10 form a substantially straight angle with each other. In the illustrated embodiment, the mouth portion 6 is closer to the axis of the container than the threaded portion 3 of the neck 15 and is also axially displaced therefrom in a direction away from the container body 1.
Beholderlegemet, som ved visse udførelsesformer består af stift og ved andre af fleksibelt termoplastisk materiale, er udformet til at holde det indre sterilt 20 indtil påfyldningstidspunktet og til efterfølgende steril opbevaring af de indledningsvis nævnte produkter. Med dette for øje er beholderen forsynet med et 1-ukkeorgan 11, der består af en aftagelig, fortrinsvis lang del 12, som er anbragt over beholderens 25 mundingsparti 6, og af en ydre, i forhold til den af tagelige del, rundtgående fastgørelsesdel 13 til tætsluttende fastgørelse af lukkeorganet på beholder-halsen 2. Fastgørelsesdelen 13 og den aftagelige del 12 er udformet ud i ét og er forbundet ved hjælp af 30 en rundtgående svækkelseszone 14, som i den viste udførelsesform er dannet af en rundtgående rille 15 på lukkeorganets 11 inderside. Svækkelseszonen 14 er i den viste udførelsesform beliggende i nærheden af beholderhalsens 2 mundingsparti 6. I den viste ud-35 førelsesform er svækkelseszonen fortrinsvis belig- 6 150726 gende nærmere beholderens akse end mundingspartiet 6.The container body, which in some embodiments consists of rigid and in others of flexible thermoplastic material, is designed to hold the inner sterile 20 until the filling time and for subsequent sterile storage of the products mentioned above. To this end, the container is provided with a 1-week member 11, which consists of a removable, preferably long portion 12, which is disposed over the mouth portion 6 of the container 25 and of an outer, relative to the removable portion 13 of the removable portion. for tightly securing the closure member to the container neck 2. The securing member 13 and the removable member 12 are formed integrally and are connected by means of a circumferential weakening zone 14 formed in the illustrated embodiment by a circumferential groove 15 on the closure member 11. inside. The weakening zone 14 is in the illustrated embodiment located near the mouth portion 6 of the container neck 2. In the embodiment shown, the weakening zone is preferably located closer to the axis of the container than the mouth portion 6.
Lukkeorganets fastgørelsesdel 13 har i den i fig. la og b viste udførelsesform en nedadvendende flange 16, 5 der svarer til formen af den indre flade 8, til at styre lukkeorganet til korrekt stilling i forhold til beholderlegemets mundingsparti 6 ved fikseringen af lukkeorganet på beholderlegemet. Jævnfør fig. la, som viser lukkeorganet i en stilling over beholdeΓΙΟ legemets mundingsparti 6, før lukkeorganet fast gøres på mundingspartiets rundtgående flange. Fastgørelsesdelen er ydermere udformet med en udadvenden-de flange 17, som ligger udenfor svækkelseszonen 14 i radialretningen og er indrettet til tætsluttende fik-13 sering til den rundtgående flade 10 på mundingspartiets flange 9. Fastgørelsesdelen 13 har en nedre flade 35, som vender mod flangens 9 øvre flade 10, hvor fastgørelsesdelen er fastgjort på beholderen.In the embodiment shown in FIG. 1 and b show a downwardly extending flange 16, 5 which corresponds to the shape of the inner surface 8, for guiding the closure member to the correct position with respect to the mouth portion 6 of the container body by fixing the closure member on the container body. See fig. 1a, which shows the closure member in a position above the containerΓΙΟ mouth portion 6 of the body before the closure member is fastened to the orbital flange of the mouth portion. Further, the fastening member is formed with an outwardly extending flange 17 which lies outside the weakening zone 14 in the radial direction and is adapted for sealingly fastening 13 to the circumferential surface 10 of the orifice portion flange 9. The fastening member 13 has a lower face 35 facing the flange. 9, upper surface 10, wherein the fastening member is secured to the container.
Den i fig. la viste udførelsesform er indrettet til 20 fiksering ved hjælp af ultralydsvejsning, hvorved fastgørelsesdelens nedre flade 35 har en svejseanvisning 36, som starter dannelsen af en svejsefuge 18, når fladerne bringes sammen under tryk, samtidig med at ultralyd tilføres området. Det er klart for en 25 fagmand, at der kan anvendes mere end en svejseanvis ning, og at svejseanvisningen eller svejseanvisningerne alternativt kan være anbragt på den øvre flade 10 af mundingspartiets udadvendende flange. Ved andre anvendelser for opfindelsen er beholderlegemet 1 og luk-30 keorganet 11 forenet ved hjælp af en samling, som op nås, f.eks. ved varmsvejsning, limning, "varmt smelte" etc.The FIG. 1a is adapted for fixation by ultrasonic welding, whereby the lower surface 35 of the attachment member has a welding instruction 36 which starts the formation of a weld joint 18 when the surfaces are brought together under pressure, while ultrasound is applied to the area. It will be clear to a person skilled in the art that more than one welding instruction may be used and that the welding instruction or welding instructions may alternatively be arranged on the upper surface 10 of the outward flange of the orifice portion. In other applications of the invention, the container body 1 and the closure member 11 are joined by means of an assembly which is reached, e.g. by heat welding, bonding, "hot melt" etc.
Fastgørelsesdelens 13 flange 17 og mundingskantpar- 150726* 7 tiets 6 flange 9 er forbundet med fladerne 10,35 ved hjælp af den rundtgående endeløse svejsefuge 18, som giver en fast, dvs. permanent, tæt samling, som ikke brydes, når beholderen åbnes. Så længe svækkelses-5 zonen 14 er intakt, udgør beholderlegemet og lukke organet således en tæt original tætning, som sikrer, at beholderens indhold forbliver sterilt. Figuren viser endvidere en udførelsesform, hvor fastgørelses-delens 13 udadvendende flange 17 er forlænget udad 10 og opad til dannelse af en skrå udad- og opadvendende krave 19, som danner en dryppekant 20, idet kraven mellem sig og den aftagelige del 12 afgrænser en rundtgående rende 21.The flange 17 of the fastening member 13 and the mouth edge pair flange 9 of the member 6 are connected to the surfaces 10,35 by means of the circumferential endless welding joint 18 which provides a fixed, i.e. permanent, tight fitting which does not break when opening the container. Thus, as long as the weakening zone 14 is intact, the container body and the closure member constitute a dense original seal which ensures that the contents of the container remain sterile. The figure further shows an embodiment in which the outwardly extending flange 17 of the fastening member 13 is extended outwardly 10 and upwardly to form an inclined outward and upwardly extending collar 19 which forms a drip edge 20, the collar between itself and the removable part 12 defining a circumferential rende 21.
I den viste udførelsesform går det nedadvendende organ 15 16 og den udadvendende flange 17 på fastgørelsesdelen 13 over i hinanden og slutter til mundingspartiet 6 ved dettes indre flade 8 og flangens øvre flade 10.In the illustrated embodiment, the downwardly extending member 15 16 and the outwardly extending flange 17 of the attachment member 13 intersect and terminate at the orifice portion 6 at its inner surface 8 and the upper face 10 of the flange.
Beholderhalsen 2 har på sin yderside umiddelbart under gevindpartiet 3 en rundtgående rille 22, i hvilken der 20 er anbragt en elastisk tætningsring 23.The container neck 2 has on its outer surface immediately below the threaded portion 3 a circumferential groove 22 in which an elastic sealing ring 23 is arranged.
Som tidligere nævnt er beholderen udformet til at holde beholderens indre steril indtil påfyldningstidspunktet. Beholderens sterilitet bevares ved hjælp af den nævnte lukning af beholderlegemet med det særlige 25 lukkeorgan 11. Lukningen udføres således sterilt ved fremstillingen, som med hensyn til tid og sted kan afvige og sædvanligvis afviger fra påfyldningstidspunktet.As mentioned earlier, the container is designed to keep the container sterile until the filling time. The sterility of the container is maintained by the said closure of the container body with the particular closure member 11. Thus, the closure is performed sterile in preparation which may differ in time and place and usually differs from the time of filling.
Ved fyldningen af beholderen fjernes et øvre stykke, dvs. et ydre parti af lukkeorganets aftagelige del 12, 30 f.eks. ved et vandret snit eller ved afbrydning ved en øvre svækkelse i lukkeorganets aftagelige del, hvorpå beholdere.n fyldes med det ønskede produkt via den 8 150726 således dannede midlertidige påfyldningsåbning ved toppen af lukkeorganets aftagelige del. Efter fyldningen forsegles lukkeorganet ved, at væggene bringes sammen ved påfyldningsåbningen og forbindes til dan-5 nelse af en permanent tæt flad samling 24 fortrinsvis ved svejsning mellem svejsebakker. Beskyttelseshætten 25 anbringes derefter på det tætte og permanent lukkede beholderlegeme, og den færdige beholder med sit indhold udsættes ved visse udførelsesformer for auto-10 klave behandlinger for at opnå fuldstændig sterilitet, medens beskyttelseshætten sikrer, at lukkeorganet og dets svækkelseszone ikke forurenes ved efterfølgende håndtering af beholderen.When filling the container, an upper piece is removed, ie. an outer portion of the removable member 12, 30, e.g. by a horizontal section or by interruption by an upper weakening of the removable member of the closure means, whereupon containers are filled with the desired product via the temporary filling opening thus formed at the top of the removable member of the closure member. After filling, the closure means is sealed by the walls being brought together at the filling opening and joined to form a permanently dense flat joint 24, preferably by welding between welding trays. The protective cap 25 is then placed on the dense and permanently closed container body, and the finished container with its contents is subjected, in certain embodiments, to autoclave treatments to achieve complete sterility, while the protective cap ensures that the closure member and its weakening zone are not contaminated by subsequent handling of the container.
Beskyttelseshætten 25 omgiver beholderens lukkeorgan 15 11 og halsen 2 og har et nedre parti 26 med et ind vendigt gevind 27, der er indrettet til skrueindgreb med beholderhalsens gevind 5. Beskyttelseshætten 25 har et cylindrisk parti 28, som ligger under gevindpartiet 26 til tætnende samvirke med tætningsringen 20 23 på beholderhalsen 2 til dannelse af en første, ydre tætning mellem beskyttelseshætten og beholderlegemet.The protective cap 25 surrounds the closure member 15 of the container 15 and the neck 2 and has a lower portion 26 with an internal thread 27 adapted for screw engagement with the container neck thread 5. The protective cap 25 has a cylindrical portion 28 which lies below the thread portion 26 for sealing cooperation with the sealing ring 20 23 on the container neck 2 to form a first outer seal between the protective cap and the container body.
Over og i nogen afstand fra partiet 26 med gevindet 27 er beskyttelseshætten udformet med en udadvenden-de afsats 29, som afgrænser en indre lomme 30 til op-25 tagelse af lukkeorganets 11 fastgørelsesdel 13. Afsat sen 29 har en indre, rundtgående, i hovedsagen plan flade 31, som med beskyttelseshætten på plads på beholderen ligger et forudbestemt stykke fra og over fastgørelsesdelens 13 flange 17. Afsatsen er udformet 30 med en indre, elastisk rundtgående tætningslæbe 32, som rager et forudbestemt stykke frem fra afsatsens flade 31 til tætnende samvirke med en bundflade 33 i fastgørelsesdelens 13 rende 21 under dannelse af en anden, indre tætning mellem beskyttelseshætten og 9 150726 det til beholderlegemet fikserede lukkeorgan 11. Tætningslæben 32 vender skråt indad, før den bringes til anlæg mod lukkeorganet, og ved påskruning af beskyttelseshætten opnås derved den ønskede tætning, idet 5 tætningslæben deformeres (bøjes til den ene side) under anlægget mod bundfladen 33 i beskyttelsesdelens 13 rende 21. Tætningslæbens funktionelle ydre side har således passende en konveks form til yderligere at lette styringen af tætningslæben indad. Den indre tætning hin-10 drer effektivt tilsnavsning af lukkeorganet omkring svæk kelseszonen 14 og sikrer ydermere, at indholdet f.eks. en væske, i tilfælde af, at beholderen allerede er blevet åbnet og derpå genforseglet, ikke løber ud i rummet mellem beskyttelseshætten og be-15 holderlegemets hals 2, f.eks. hvis beholderen væltes.Above and at some distance from the portion 26 with the thread 27, the protective cap is formed with an outwardly extending ledge 29 which defines an inner pocket 30 for accommodating the fastening portion 13 of the closure member 11. Deposition 29 has an inner, circumferential, substantially a flat surface 31 which, with the protective cap in place on the container, lies a predetermined portion from and above the flange 17 of the attachment member 13. a bottom surface 33 in the groove 21 of the fastening member 13 to form a second, internal seal between the protective cap and the closure member fixed to the container body 11. The sealing lip 32 faces inclined inwardly before being brought into contact with the closure member and thereby securing the protective cap desired sealing, deforming the sealing lip (bending to one side) under the abutment against the bottom surface 33 in protection Thus, the functional outer side of the sealing lip 13 has a convex shape to further facilitate the control of the sealing lip inwardly. The inner seal effectively prevents contamination of the closure member around the weakening zone 14 and further ensures that the contents e.g. a liquid, in the event that the container has already been opened and then resealed, does not run into the space between the protective cap and the neck 2 of the container body, e.g. if the container is overturned.
Den i fig. 2 viste udførelsesform er indrettet til fastholdelse af beskyttelseshætten 25a til beholder-legemet la ved snapvirkning. Med dette for øje er beskyttelseshætten ved sin nedre del udformet med et 20 snaporgan (vulst) 37, som vender mod hættens midter akse og snapper ind i en tilsvarende rille 39 i beholderens hals 2a. Over rillen er halsen udformet med en nedad- og udadvendende afgrænsningsflade 44, som snaporganet ligger an imod og mod hvilket det ekspan-25 derer under trinneit lige før det snapper ind i rillen 39. Vulsten 37 har ved overgangen til den nedre kantflade 40 på beskyttelseshætten en indadvendende, rundt-gående skrå flade 38 for at styre beskyttelseshættens vulst 37 udad, når beskyttelseshætten anbringes på be-30 holderlegemet. Over den skrå flade 38 har vulsten en afgrænsningsflade (tætnings flade) 43, som vender mod hættens akse.The FIG. 2 is arranged for holding the protective cap 25a to the container body 1a by snap action. To this end, the protective cap is formed at its lower part with a snap member (bead) 37 which faces the middle axis of the cap and snaps into a corresponding groove 39 in the neck 2a of the container. Above the groove, the neck is formed with a downwardly and outwardly delimiting delimiting surface 44 against which the snap means abuts and against which it expands during step rivet just before snap into the groove 39. The bead 37 has at the transition to the lower edge surface 40 of the protective cap an inwardly facing circumferentially inclined surface 38 for guiding the bead 37 bead outwardly as the protective cap is placed on the container body. Above the inclined surface 38, the bead has a bounding surface (sealing surface) 43 facing the cap axis.
Lukkeorganet 11a er her vist som en udførelsesform med et ydre nedadvendende styreorgan 16a, som går over 150726 ίο i den opadvendende krave 19, hvis øvre afgrænsnings-kant danner dryppekanten Z0. Når lukkeorganet anbringes på beholderlegemet, samvirker styreorganet med en ydre afgrænsningsflade 45 på mundingspartiets ud-5 advendende rundtgående flange 9a for at lede lukke organet til den korrekte stilling til fiksering på beholderlegemet.The closure member 11a is shown here as an embodiment with an outer downwardly directed guide member 16a which extends beyond the upwardly facing collar 19, the upper bounding edge of which forms the drip edge Z0. When the closure member is placed on the container body, the guide member cooperates with an outer bounding surface 45 on the outwardly extending flange 9a of the orifice portion 5 to guide the closure member to the correct position for fixation to the container body.
Ved denne udførelsesform for opfindelsen har flangen 9a en lidt bøjet øvre flade 10a, som opadtil afgræn-10 ser fastgørelsesdelens samvirkende, rundtgående fast gørelsesdel 13a. Fastgørelsesdelens øvre flade 33a har en form svarende til den øvre flade 10a, hvilket betyder, at når den aftagelige del 12 er fjernet, danner fastgørelsesdelens øvre flade 33a en indad-15 og opadvendende øvre afgrænsningsflade på mundings- åbningen, som dannes, når den aftagelige del fjernes.In this embodiment of the invention, the flange 9a has a slightly bent upper surface 10a which defines upwardly 10 the cooperating, circumferential fastening part 13a of the fastener part. The upper surface 33a of the fastener portion has a shape similar to the upper surface 10a, which means that when the removable portion 12 is removed, the upper surface 33a of the fastener portion forms an inward and upwardly upper delimiting surface on the orifice which is formed when the removable portion is formed. part removed.
Fastgørelsesdelen 13a, som forbliver fastgjort til flangen 9a, udgør en dimensionsstabiliserende forstærkning af flangen, og specielt udformningen af styre-20 organet 16a og kraven 19 bidrager til at gøre mun dingsåbningen stabil, når den aftagelige del 12 er fjernet.The fastening member 13a, which remains attached to the flange 9a, provides a dimensionally stabilizing reinforcement of the flange, and in particular the design of the guide member 16a and the collar 19 helps to make the orifice opening stable when the removable portion 12 is removed.
Beskyttelseshætten 25a er i området mellem den udadvendende afsats 29 og snaporganet 37 udformet med en 25 nedad- og udadvendende indre flade 41, som samvirker med en tilsvarende anbragt, ydre anlægsflade 42 på beholderlegemets hals 2a. Afstanden mellem og formen af den nedad- og udadvendende flade 41 og snaporganet 37 for beskyttelseshætten er tilpasset afstanden 30 mellem og formen af den nævnte anlægsflade 42 og rillen 39 i halsen 2a, så at beskyttelseshætten, når den er snappet på, indtager en fikseret, aksial stilling i forhold til beholderlegemet.The protective cap 25a is formed in the region between the outwardly extending ledge 29 and the snap member 37 with a downward and outwardly facing inner surface 41 which cooperates with a correspondingly placed outer abutment surface 42 on the neck 2a of the container body. The distance between and the shape of the downward and outward face 41 and the protective cap snap member 37 is adapted to the distance 30 between and the shape of said abutment surface 42 and the groove 39 of the neck 2a so that the protective cap, when snapped on, occupies a fixed, axial position relative to the container body.

Også ved udførelsesformen ifølge fig. 2 udøver beskyttelseshætten efter monteringen en indadrettet kraft på tætningsringen 23, hvorved kraften deformerer tætningsringen til tætnende afgrænsning af rummet 5 mellem beskyttelseshætten 25a og beholderlegemets mundingsparti 6.Also in the embodiment of FIG. 2, after the mounting, the protective cap exerts an inward force on the sealing ring 23, whereby the force deforms the sealing ring to sealingly define the space 5 between the protective cap 25a and the mouth portion 6 of the container body.
I en foretrukken udførelsesform er snaporganets indad-vendende afgrænsningsflade 43 beliggende længere borte fra beholderens akse end nogen del af halspartiets 2a 10 ydre flade i området mellem mundingspartiets rundt- gående flange 9a og den nedad- og udadvendende afgrænsningsflade 44 umiddelbart over indsnapningsril-len 39. Herved sikres, at tætningsringen 23 ikke forskydes ud af rillen 22 ved påsætningen af beskyttelses-15 hætten 25a.In a preferred embodiment, the inward bounding surface 43 of the snap member is located further away from the axis of the container than any portion of the outer surface of the neck portion 2a 10 in the region between the orifice flange 9a of the orifice portion and the downward and outward bounding surface 44 immediately above the indentation groove 39. In this way, it is ensured that the sealing ring 23 is not displaced from the groove 22 by the application of the protective cap 25a.
Ued udførelsesformer for opfindelsen, hvor beskyttelseshætten snappes på beholderlegemet, er der større frihed ved tilpasningen af størrelsen og formen af tværsnittet gennem beholderens hals og dens mundings-20 del samt gennem lukkeorganet til de af det opbevarede produkt stillede krav. Dette tværsnit behøver kun at have en rund form hvis beskyttelseshætten er gevindskåret.In embodiments of the invention in which the protective cap is snapped onto the container body, there is greater freedom in adjusting the size and shape of the cross-section through the neck of the container and its mouth portion and through the closure means to the requirements of the stored product. This cross-section only needs to have a round shape if the protective cap is threaded.
Fig. 3a og b viser en alternativ udførelsesform for opfindelsen, hvor mundingspartiets rundtgående ud-25 ragende flange 9b har en svejseanvisning 36a. Endvidere er den rundtgående rille 15 og således lukke-organets- 11b svækkelseszone 14 anbragt mellem svejseanvisningen 36a (svejsefugen 18) og styreorganet 16.FIG. 3a and b show an alternative embodiment of the invention, in which the circumferential flange 9b of the orifice portion has a welding instruction 36a. Further, the circumferential groove 15, and thus the weakening zone 14 of the closing member 11b, is arranged between the welding instruction 36a (the welding joint 18) and the control means 16.
I denne udførelsesform udgør den fjernede del 12 30 efter åbningen af den originalforseglede beholder også et organ til midlertidig genforsegling af beholderen, især i de udførelsesformer hvor styreorganet 16 ligger an mod mundingspartiets indre flade 8.In this embodiment, after the opening of the original sealed container, the removed portion 12 also constitutes a means for temporarily resealing the container, especially in the embodiments where the guide member 16 abuts the inner surface 8 of the mouth portion.

Den aftagelige dels dimensioner forhindrer, at den kan forskydes til beholderens indre, efter at beholderen er åbnet.The dimensions of the removable portion prevent it from being displaced to the interior of the container after opening the container.
Fig. 3c og d viser en udførelsesform, hvor lukke-5 organets 11c svækkelseszone 14 er udformet ved, at rillen 15 er anbragt på lukkeorganets yderside. Figurerne viser endvidere muligheden for at udforme lukkeorganet uden noget styreorgan.FIG. 3c and d show an embodiment in which the weakening zone 14 of the closure member 11c is formed by the groove 15 being arranged on the outside of the closure member. The figures further show the possibility of forming the closing means without any control means.
Fig. 4 a-b viser alternative udførelsesformer for 1U tætningsorganet 32. I fig. 4a er dette udformet som en udad- og nedadvendende læbe 32b og i fig. 4b som en nedadvendende tilspidset udhugning 32c.FIG. 4 a-b show alternative embodiments of the sealing member 32. In FIG. 4a, this is formed as an outward and downward lip 32b and in FIG. 4b as a downward tapered notch 32c.
Fig. 5 viser en udførelsesform for beholderen ifølge opfindelsen, hvor beskyttelseshætten 25d er indrettet 15 til at tilvejebringe brydningen af svækkelseszonen 14 ved påvirkning af den aftagelige del 12d.FIG. 5 shows an embodiment of the container according to the invention, in which the protective cap 25d is arranged 15 to provide the breaking of the weakening zone 14 by actuating the removable part 12d.
I den viste udførelsesform er fastgørelsesdelen 13d udformet med et opadvendende rundtgående parti 46, som ved hjælp af svækkelseszonen 14 er forbundet 20 med den aftagelige del 12d. Svækkelseszonen er således beliggendei en afstand fra beholderens akse, som i hovedsagen er større end den tilsvarende minimumsafstand for tømningsåbningen 34, der dannes, når den aftagelige del 12d fjernes. Den aftagelige del er endvidere 25 udformet med et rundtgående vægparti 47, der i hoved sagen danner en ret vinkel med beholderens akse, og som er forbundet med svækkelseszonen 14. I figuren består denne forbindelse af en væg 49, som i hovedsagen er orienteret i aksial retning. Men ved visse an-30 vendeis er er svækkelseszonen 14 direkte forbundet med den aftagelige dels 12d nævnte rundtgående parti 47. Svækkelseszonen har ydermere en sådan stilling, at 13 150726 dens afstand fra beholderaksen i hovedsagen er større end den tilsvarende minimumsafstand for tømningsåbningen 34, som dannes ved fjernelse af den aftagelige del 12.In the illustrated embodiment, the fastening part 13d is formed with an upwardly extending circumferential portion 46 which is connected by the weakening zone 14 to the removable part 12d. Thus, the weakening zone is located at a distance from the axis of the container which is substantially greater than the corresponding minimum distance of the emptying aperture 34 formed when the removable portion 12d is removed. The detachable member is further provided with a circumferential wall portion 47 which generally forms a right angle to the axis of the container and which is connected to the weakening zone 14. In the figure, this connection consists of a wall 49, which is generally oriented in axial position. direction. However, in certain applications, the weakening zone 14 is directly connected to the circumferential portion 47 of the removable part 12d. The weakening zone also has such a position that its distance from the container axis is substantially greater than the corresponding minimum distance of the discharge aperture 34 which is formed by removal of the removable portion 12.
5 I den i figuren viste udførelsesform er beskyttelses hættens 25d udadvendende afsats 29d udformet som et trin. Afsatsens nærmest beholderaksens liggende del danner et rundtgående parti 48, som med beskyttelseshætten anbragt på beholderen indtager en stilling i 10 forhold til den aftagelige dels 12d rundtgående parti 47, som indebærer, at de to rundtgående partier 47, 48 er aksialt forskudt i forhold til hinanden så at de ligger i en vis afstand fra hinanden. Andre henvisningstal i denne figur og viste detaljer har deres 15 modsvarighed i de tidligere beskrevne figurer.In the embodiment shown in the figure, the outwardly facing ledge 29d of the protective cap 25d is formed as a step. The lying portion of the ledge closest to the container axis forms a circumferential portion 48 which, with the protective cap placed on the container, occupies a position 10 relative to the removable portion 12d circumferential portion 47, which implies that the two circumferential portions 47, 48 are axially displaced relative to each other. so that they are at some distance from each other. Other reference figures in this figure and details shown have their correspondence in the previously described figures.
Ued alternative udførelsesformer for beholderen ifølge opfindelsen kan svækkelseszonen 14 være fremstillet således, at materialevæggen har en mindre styrke end det omgivende materiale, f.eks. ved materialefortynding, 20 særlig molekylorientering eller krystallisering.In alternative embodiments of the container according to the invention, the weakening zone 14 can be made such that the material wall has a less strength than the surrounding material, e.g. by material dilution, especially molecular orientation or crystallization.
Ved alternative udførelsesformer for opfindelsen kan den udadvendende krave 19 (se fig. 2) endvidere være udformet som et tætningsorgan, der ligger an mod dens indre rundtgående flade på beskyttelseshættens af-25 sats 29. Ved visse anvendelser udgør kraven 19 det eneste tætningsorgan i området for fastgørelsesdelen 13.Further, in alternative embodiments of the invention, the outward-facing collar 19 (see Fig. 2) may be formed as a sealing member abutting its inner circumferential surface on the cover of the protective cap 29. In certain applications, the collar 19 is the only sealing member in the region. for the attachment part 13.
Ved brug af en original fyldt beholder fjernes først beskyttelseshætten, hvorpå beholderlegemet åbnes ved 30 oprivning af svækkelseszonen 14. Der dannes således en tømmeåbning 34, som er omgivet af den øvrige fastgørelsesdel 13. Tømning af væskeprodukter fra 14 150726 beholderen finder sted på styret måde, idet dryppe-kanten 20 eller det opadvendende, rundtgående parti 46 hindrer, at væsken løber langs beholderlegemets yderside. Når materialet er i form af en pasta, 5 tjener dryppekanten 20 eller partiet 46 som en styre-kant for et værktøj, som afskærer pastastrenge, så at pastaen ikke strømmer eller falder ned langs beholderens yderside.When using an original filled container, the protective cap is first removed and the container body is opened upon tearing of the weakening zone 14. Thus, a discharge opening 34 is formed which is surrounded by the other attachment part 13. Emptying of liquid products from the container takes place in a controlled manner. the drip edge 20 or the upwardly extending portion 46 preventing the liquid from running along the outside of the container body. When the material is in the form of a paste, the drip edge 20 or portion 46 serves as a guide edge for a tool which cuts off the pasta strands so that the paste does not flow or fall along the outside of the container.
Beholderlegemet kan genforsegles ved hjælp af be-10 skyttelsehætten, hvis en del af dens indhold skal spares kortvarigt til en senere lejlighed, idet de ydre og indre tætninger 23, 32, 19 danner en tilfredsstillende lukning.The container body may be resealed by means of the protective cap if a portion of its contents is to be saved briefly for a later occasion, the outer and inner seals 23, 32, 19 forming a satisfactory closure.
I de udførelses former for opfindelsen som er vist i 13 fig. 1 til 4, åbnes beholderen mest enkelt ved, at den aftagelige del 12 presses til side, indtil en del af dens svækkelseszone brydes, hvorpå de øvrige dele af svækkelseszonen rives op. Åbning kan finde sted enten ved afskruning og fjernelse af beskyttelseshætten, 20 hvorpå den aftagelige del brydes løs, eller ved af skruning af beskyttelseshætten, indtil den sidder relativt løst på beholderens mundingsparti, hvorpå den bevæges til side og derved tilvejebringer den påvirkning af den aftagelige del, som kræves til åbning af 25 beholderen.In the embodiments of the invention shown in FIG. 1 to 4, the container is most easily opened by pushing the removable portion 12 aside until a portion of its weakening zone is broken, and the other parts of the weakening zone are torn apart. Opening can take place either by unscrewing and removing the protective cap, 20 on which the detachable portion is dislodged, or by unscrewing the protective cap until it sits relatively loosely on the mouth portion of the container, where it is moved aside thereby providing the effect of the removable portion. , which is required to open the container.
Ued den i fig. 5 viste udførelsesform åbnes beholderen ved nedadgående forskydning af beskyttelseshætten 25d mod beholderens bund, idet beskyttelseshætten skrues ned. Beskyttelseshættens rundtgående parti 48 30 bringes først til anlæg mod den aftagelige dels 12d tilsvarende rundtgående parti 47, hvorpå den aftagelige dels rundtgående parti 47 ved fortsat nedadgående skruning af beskyttelseshætten bryder forbin- 150726' 15 delsen i svækkelseszonen 14 under fortsat nedadrettet forskydning. Da svækkelseszonens afstand fra beholder-aksen i hovedsagen er større end den tilsvarende minimumsafstand for den dannede tømningsåbning 34, er der 3 ingen risiko for, at den fjernede del falder ind i beholderens indre. Ved en genforseglet beholder ligger tætningen 32d an mod fastgørelsesdelens øvre afgrænsningsflade .Without the one shown in FIG. 5, the container is opened by downward displacement of the protective cap 25d towards the bottom of the container, as the protective cap is screwed down. The circumferential portion 48 of the protective cap is first brought into contact with the detachable portion 12d corresponding to the circumferential portion 47, upon which the removable portion 47 of the downwardly extending screw of the protective cap breaks the connection in the weakening zone 14 during continued downward displacement. Since the weakening zone's distance from the container axis is substantially greater than the corresponding minimum distance of the formed discharge aperture 34, there is no risk of the removed portion falling into the interior of the container. In a resealed container, the seal 32d abuts the upper bounding surface of the attachment member.
Ved manuel åbning af beholderen kommer fingrene blot 10 i kontakt med den aftagelige dels øvre parti, og der er derfor ingen risiko for, at svækkelseszonen og fastgørelsesdelen med dryppekant bliver forurenet ved berøring. På grund af udformningen af den aftagelige del og svækkelseszonens beliggenhed opnås endvidere 15 den fordel, at beholderen kan åbnes med et mekanisk organ, som f.eks. kan have et hul, som svarer til og optager den aftagelige del og derved muliggør et brydemoment og eventuelt også et drejemoment. Ved hjælp af et sådant organ fjernes den aftagelige del, 20 uden at den har været i kontakt med fingrene.By manually opening the container, the fingers only come into contact with the upper portion of the removable portion, and therefore there is no risk that the weakening zone and the drip-edge fastening portion will be contaminated by touch. Further, due to the design of the removable portion and the location of the weakening zone, the advantage is that the container can be opened with a mechanical means such as e.g. may have a hole which corresponds to and occupies the removable portion thereby enabling a torque and possibly also a torque. By means of such a device, the removable portion 20 is removed without having been in contact with the fingers.
Ved udformning af beholderen ifølge opfindelsen som en beholder til rensevæske skal lukkeorganet fortrinsvis være dimensioneret til dannelse af en relativt stor tømmeåbning af størrelsesordenen ca. 25 mm ved et cirku-25 lært tværsnit, når den aftagelige del fjernes. En sådan stor åbning tillader, at luft kan strømme ind i beholderen under tømmeprocessen, hvorved der opnås en jævn væskestrøm. Ved de anvendelser hvor beholderen benyttes til opbevaring af et pulver, vælges åbningen som regel endnu 30 større for at lette fjernelsen af pulveret fra behol deren. Hvor beholderne er beregnet for pasta eller lignende produkter vælges som regel mindre dimensioner for åbningen, så at den tilpasses det i beholderen opbevarede produkt. F.eks. i tilfælde af pastaIn designing the container according to the invention as a container for cleaning liquid, the closure means should preferably be sized to form a relatively large discharge opening of the order of approx. 25 mm at a circular cross section when the removable portion is removed. Such a large opening allows air to flow into the container during the emptying process, thereby obtaining a steady flow of liquid. In the applications where the container is used for storing a powder, the aperture is usually chosen even larger to facilitate removal of the powder from the container. Where the containers are intended for pasta or similar products, smaller dimensions are usually chosen for the opening to be adapted to the product stored in the container. Eg. in the case of pasta
