This ring has two or more inward projections (6) which enter an annular groove (7) in the container opening on initial closure, and hold the ring in position when the cap is removed. There may be four such connecting bridges with four projections spaced between them. The length of the projections is pref. about one eighth of the ring diameter.

Description

Die vorliegende Erfindung bezieht sich auf eine sich bei ihrer Anordnung auf dem mit ihr zu verschliessenden Behälter automatisch versiegelnde Schraubkapsel, womit es möglich ist zu prüfen ob der betreffende Behälter noch unberührt ist oder bereits geöffnet wurde.The present invention relates to a screw capsule which is automatically sealed when it is arranged on the container to be closed, with which it is possible to check whether the container in question is still untouched or has already been opened.

Bekannt sind derartige versiegelbare Verschlüsse, welche sich dazu eignen um die Schraubkapsel bei ihrer erstmaligen Anordnung auf dem zu verschliessenden Behälter zu versiegeln, wobei aber zwecks öffnung des Behälters die Versieglung gelöst werden muss und diese zu diesem Zweck meistens mit einem Vorsprung oder einer Lippe versehen ist, und wobei der eigentliche versiegelnde Teil sich ganz oder nur teilweise vom mit der Schraubkapsel verschlossenen Behälter bzw. von der eigentlichen Schraubkapsel löst, dies alles derart, dass es immer die Gefahr gibt, dass dieser Teil in den Behälter oder in das Bad, worin der Inhalt des Behälters ausgegossen wird, fällt, mit sämtlichen sich daraus ergebenden Nachteilen.Such sealable closures are known, which are suitable for sealing the screw capsule when it is first placed on the container to be sealed, but for the purpose of opening the container the sealing must be released and for this purpose it is usually provided with a projection or a lip , and wherein the actual sealing part is completely or only partially detached from the container closed with the screw capsule or from the actual screw capsule, all in such a way that there is always the risk that this part in the container or in the bath, in which the Contents of the container is poured out, with all the resulting disadvantages.

Der vorliegenden Erfindung ist nun die Aufgabe gestellt eine sich dadurch auszeichnende versiegelbare Schraubkapsel zu schaffen, dass die erbrochene Versieglung auf dem zu öffnenden Behälter sitzen bleibt und daher nicht in denselben fallen oder sonstwohin geraten kann.The object of the present invention is now to create a sealable screw capsule which is distinguished by the fact that the vomited seal remains on the container to be opened and therefore cannot fall into the container or get anywhere else.

Ausserdem ist die erfindungsgemässe Schraubkapsel derart gedacht, dass das Versiegeln während des Aufschraubens derselben mit einem deutlich hörbaren Laut stattfindet.In addition, the screw capsule according to the invention is ge thought that the sealing takes place with a clearly audible sound while unscrewing them.

Die erfindungsgemässe Schraubkapsel besteht zu diesem Zweck in wensentlichen aus einer eigentlichen Schraubkapsel und einem Versieglungsring, welche an zwei oder mehreren Stellen mittels kleiner örtlicher Verbindungen oder Stege miteinander verbunden sind, wobei dieser Versieglungsring an zwei oder mehreren Stellen einen nach innen gerichteten Zahn aufweist, dessen Aufgabe es ist mit einer and der Öffnung des mit der betreffendend Schraubkapsel zu verschliessenden Behälters zu diesem Zweck vorgesehenen Umfangsrille zusammenzuwirken.For this purpose, the screw capsule according to the invention consists essentially of an actual screw capsule and a sealing ring, which are connected to one another at two or more points by means of small local connections or webs, this sealing ring having an inwardly directed tooth at two or more points, its task it is to cooperate with a circumferential groove provided for this purpose at the opening of the container to be closed with the screw capsule in question.

The characteristics and advantages of the system according to the invention are explained by the detailed description of a preferred embodiment below. This description, which is given without any restrictive intent, takes place with reference to the attached drawing, where
  • FIG. 1 shows a side view of part of a container closed with a screw capsule according to the invention;
  • Figure 2 shows a side view of a screw capsule according to the invention on an enlarged scale;
  • Figure 3 shows a top view of the screw capsule according to Figure 2;
  • Figure 4 shows a section of the screw capsule in question made according to line IV-IV of Figure 3;
  • FIG. 5 shows a section similar to FIG. 4 of the screw capsule according to the invention arranged on the container in question;
  • Figures 6 and 7 show parts F6 and F7 of Figure 5 on an enlarged scale; and
  • 8 shows the upper part of a container with a screw capsule according to the invention removed from it.

Wie aus den Abbildungen ersichtlich ist, besteht die erfindungsgemässe Schraubkapsel aus einer eigentlichen Schraubkapsel 1 und einem Versieglungsring 2, wobei diese Schraubkapsel auf beliebige geeignete Weise mit einem Behälter 3 zwecks Schaffung einer zweckmässigen Abdichtung zusammenwirken kan.As can be seen from the figures, the screw capsule according to the invention consists of an actual screw capsule 1 and a sealing ring 2, this screw capsule being able to interact with a container 3 in any suitable manner in order to create a suitable seal.

Erfindungsgemäss ist die Schraubkapsel mit unten nicht mit dem Versieglungsring 2 verbundenen Aussenrippe 4 versehen, wobei neben diesen Rippen schwache Verbindungen zwischen der eigentlichen Schraubkapsel 1 und dem Versieglungsring 2 in der Form einer oder mehrer kleiner örtlicher Verbindungselemente oder Stege 5 vorgesehen sind.According to the invention, the screw capsule is provided with an outer rib 4 not connected to the sealing ring 2 at the bottom, weak connections between the actual screw capsule 1 and the sealing ring 2 in the form of one or more small local connecting elements or webs 5 being provided in addition to these ribs.

Der vorgenannte Versieglungsring hat an seiner Innenseite zwischen den vorgenannten Verbindungselementen 5 einen nach innen gerichten, mit einem Rand 7 des Behälters 3 zusammenwirkendend Zahn 6. Die Länge dieses Zahnes entspricht ungefähr einem Achtel des örtlichen Durchmessers des Versieglungringes. Dies führt dazu, dass, während des erstmaligen Aufschraubens der erfindungsgemässen Schraubkapsel auf dem Behälter 3, die vier Zähne 6 nacheinander unter dem vorgenannten Rand 7 einhaken. Der hierbei jedesmal erzeugte deutlich hörbare Klicklaut bedeutet, dass die Verriegelung jedesmal tatsächlich stattgefunden hat. Ausserdem, während des Losschraubens der Schraubkappe 2, verhindern die Zähne 6 die Mitnahme des Versieglungsringes nach oben, so dass dieser auf dem Behälter zurückbleibt und die schwächeren Teile 5 zwischen der eigentlichen Schraubkappe 1 und dem Ring 2 nacheinder aufgebrochen werden.The aforementioned sealing ring has on its inside between the aforementioned connecting elements 5 an inwardly directed tooth 6 which cooperates with an edge 7 of the container 3. The length of this tooth corresponds approximately to one eighth of the local diameter of the sealing ring. This means that, when the screw capsule according to the invention is first screwed onto the container 3, the four teeth 6 hook one after the other under the aforementioned edge 7. The clearly audible click sound generated each time means that the locking has actually taken place each time. In addition, while unscrewing the screw cap 2, the teeth 6 prevent the sealing ring from being carried upwards, so that it remains on the container and the weaker parts 5 between the actual screw cap 1 and the ring 2 are broken open one after the other.

Dies hat zur Folge, dass, wie es deutlich aus der Abbindung 8 ersichtlich ist, die Schraubkapsel losgeschraubt wird und der auf dem Behälter zurückbleibende Versieglungsring festgehalten wird und deshalb nicht in den Behälter oder in ein Bad fallen kann, während das Durchbrechen des Ringes jedenfalls gesichert ist.The result of this is that, as can be clearly seen in FIG. 8, the screw capsule is unscrewed and the sealing ring remaining on the container is held in place and therefore cannot fall into the container or into a bath, while breaking the ring in any case ensures it is.

Die vorliegende Erfindung beschränkt sich selbstverständlich keineswegs auf das in den vorhergehenden Zeilen beschriebene und durch die beiliegenden Abbildungen erlaüterte Durchführungsbeispiel, sondern eignet sich für die verschiedenartigsten Abänderungen, Ergänzungen und Anpassungen der betreffenden Schraubkapsel hinsichtlich Form und Grösse, vorausgesetzt natürlich, dass der Erfinderungsrahmen nicht überschritten wird.The present invention is of course in no way limited to the exemplary embodiment described in the preceding lines and explained by the accompanying figures, but is suitable for the most varied of modifications, additions and adjustments to the screw capsule concerned in terms of shape and size, provided, of course, that the scope of the invention is not exceeded .
