Description

Opening device for packaging containers

The present invention relates to an opening device for a packaging container, in particular to an opening device for a liquid package made of a strip or sheet of material according to the preamble of claim 1 and for a device according to claim 21 Covers for such devices.

Such a device is disclosed, for example, in EP 0658 480 A1 or in EP 95 920 224.3, wherein a packaging made, in particular, of a material strip or sheet has a hole-shaped or hole-marked opening, at least one base The parts are arranged within the scope of the opening of the container. In addition, this known device has at least one cover for sealing the opening, the cover being arranged on the base so that the opening can be both closed and opened.

The packaging, which is preferably made of laminated material, can be made from a continuous material strip or from individual blanks, wherein the laminated material is made of a cardboard or paper core with a thermoplastic layer and optionally aluminum foil. Such packages usually have an opening device which is formed by a so-called tear-off strip which is torn off when the package is opened. Also disclosed in EP-A-0 558 946 is that this package has an outer thermoplastic structure surrounding the band. Such a thermoplastic structure can have a mouthpiece and a lid, which are folded together with a hinge function and snap into each other rigidly according to the design. In most cases the strip below this thermoplastic structure has a part which is not sealed and is folded over the sealed section of the strip. In this way, the strap can be easily pinched and torn off when the package is opened, so as to realize the opening of the hole or the hole mark.

In addition, for example in DE 44 09 946A1 or DE 199 04 837C1, it is disclosed that the packaging container consists of a packaging material strip consisting mainly of paper or plastic material, by means of a membranous film or a tear-off tongue made of synthetic resin. The opening of the packaging container can be hermetically closed. The film can be pierced with a straw or torn off the tear off tongue when opening the opening seal. In this case the tear-off tab can be connected to the innermost layer of the laminate of the container in order to meet the requirements for sterility when filling the container. This layer is torn off during opening and is then torn off together with the tear-off tongue in the opening range.

Finally in WO 00/47480 it is disclosed that there is an opening device in the open position, the opening device is used to open the seal of the sealed container, there is an opening section for opening the seal of the sealing part, an operating section is used to operate the opening section , and a supporting section for supporting the operating section, so that the device for opening the seal is firmly fixed on the sealed container. The opening section penetrates, for example, hinge-like inwardly through the optionally pre-perforated hole.

The above-mentioned opening devices all have a thermoplastic structure arranged on the opening of the packaging container, and the thermoplastic structure is fixed on the surface of the container within the range of the opening by using a hot-melt adhesive. Disadvantages of such conventional opening devices are, inter alia, that laying such thermoplastic structures is made more difficult and that the thermoplastic structures cannot be reliably prevented from falling out during transport, mostly because expensive positioning devices must be used.

Moreover, the material edge of the opening of the packaging container cannot be sealed by the thermoplastic structure laid on the upper surface of the packaging container, so that the packaging material at the edge of the opening will be softened when the liquid in the container is poured. It is also difficult to sterilize or sterilize such opening configurations prior to forming and filling the package.

And when, for example, the unsealed, turned-over folded segment is pressed against the sealed segment during manufacture and handling in the filling machine, so that the folded segment is pressed against the sealed segment and Thus it cannot be pinched, or it is very difficult to pinch the strip for sealing the opening or to tear or penetrate the strip when the thermoplastic structure is glued to the strip for tearing due to misalignment. And in the known opening device, the strip part is often left in the pouring opening, thus causing it to be difficult to pour out the liquid in the container smoothly.

In JP 09 254 967 an opening device is disclosed, the base of which is glued on the inner side of the package within the scope of the opening.

The object of the present invention is to make further improvement to the opening device of existing packing container, so that overcome described problem and propose a kind of opening device, described opening device is made simple and cheap, and has less structural height, Thereby, a smooth production and sale of the packaging, which is suitable for various packaging and opening methods, can be guaranteed.

The object of the invention is achieved by the features of the characterizing part of claim 1 . Advantageous embodiments of the invention are described and further specified in the dependent claims. The cover of the device according to the invention is described in claim 21 .

The opening device of the packaging container according to the invention, wherein the packaging container is made in particular of a laminated material with a core made of paper or cardboard, said laminated material being laminated to a thermoplastic layer and optionally aluminum, The laminated material is usually produced from a continuous material strip, but can also be produced from individual sheets of material, the opening device has at least one base part, which is arranged on the opening of the packaging container, wherein The openings in the material web or sheet are preformed, for example by stamping.

The cover is used to seal or cover the opening, and the cover is arranged on the base so that the opening is covered or sealed. According to the invention, the cover has a double function: on the one hand, the cover has a connecting part connecting the cover to the base after the base part has been placed on the container, and on the other hand, the cover has a functional part which performs a predetermined function. In particular, the cover has hinged, latching, snapping, hinged or screw connections for the connection to the base part.

The cover preferably has a base part, wherein the base part is connected to the base part by means of hinged, latching, clipping, hinged or screw connections. The lid preferably has a closure part as a functional part, which serves to seal the package and which is connected to the lid, for example by means of a hinged, snap-on, snap-fit, hinge or screw connection. base connection.

The covers can be manufactured and installed individually, and can be shaped differently and fulfill different tasks depending on the intended application. The cover is preferably only provided in a second manufacturing step when the package with the base is filled with liquid, folded and produced as a packaged or sold product.

The cover has as a functional part a cover part for resealing the opening, a protective part for preventing damage to the base part during transport of the packaging or, for example, also has a quality assurance seal, which is on the When the packaging container is opened for the first time, it will be irreversibly changed or destroyed, so that it can be clearly determined whether a third party has opened the packaging beforehand. And other functions can also be realized, such as setting the paper printed with usage information on the lower part of the cover, sticking a timely note, setting a pattern suitable for children and the combination of the above functions.

Instead of the usual strip or membrane for sealing the opening of the packaging container, the opening device according to the invention preferably has an opening element which can be torn off to allow the opening of the container and which is connected to the base element before the container is opened. The base part and the opening part are preferably formed or injection molded from a common thermoplastic structure, so that the base part is only separated from the opening part when the first opening of the container is achieved by tearing off the opening part.

Wherein according to a preferred embodiment of the present invention, the base part is fixed on the edge range of the opening of the packaging container, so that it completely surrounds the outer and/or inner edge range of the container and thereby realizes that in the opening range, especially at the edge of the container, Sealing of the edges of the packaging material in the area of the inner opening.

The preferably complete encirclement of the laminated material edge of the packaging container prevents, for example, liquids in the container from penetrating into the laminated material and softening of the material edge in the region of the opening. At the same time, the base part of the opening device according to the invention can be fixed reliably and firmly on the packaging container, so that the opening device is prevented from being torn off during forming, folding and filling of the container, as well as during sale and at the end user.

The base part consists, for example, of an injection-molded plastic which can be injected around the edges of the opening using an injection-molding process in order to seal the edges of the container material. This so-called DIM-process (Direct Plastic Injection Molding) enables a rapid and inexpensive production of the base part, which is therefore firmly injection-molded around the opening of the packaging container and is preferably integrated with the base part in one operation. The opening parts and other parts if necessary are manufactured together at the same time.

Furthermore, the opening device according to the invention also has a cover which is produced separately. A functional separation of the opening device can also be achieved by separating the base part from the cover part. Various materials, respectively adapted to the application, can therefore be used for the base part and the cover part.
