Abstract

The container closure has a lid, below which is arranged a sealing insert (1) made of sheet material. When the container is closed, the edge (4) of the sealing insert rests against the inside wall of a container in a circumferential groove. The sealing insert (1) has a gripping flap (2) on its upper side. The sealing insert (1) and the gripping flap (2) are vacuum-formed from the sheet material in the same operation and are integral. The gripping flap (2) is arranged off-centre on the sealing insert (1) and projects at an acute angle from the surface thereof in the unloaded state. The sealing insert (1) is lifted off the container by pulling the gripping flap (2). The sealing insert (1) can be removed from the container without difficulty and without special instructions without any parts of the sealing insert (1) dropping into the contents. <IMAGE>

   PATENTANSPRUCH
Behälterverschluss nach dem Patentanspruch des Hauptpatentes, dadurch gekennzeichnet, dass sich an der Oberseite des Dichteinsatzes eine Greiflasche befindet.



   UNTERANSPRüCHE
1. Verschluss nach Patentanspruch, dadurch gekennzeichnet, dass die Greiflasche aussermittig angeordnet ist und sich ihr mit dem Dichteinsatz verbundenes Ende aussen befindet, so dass ihr freies Ende gegen das Zentrum   Jedes    Dichteinsatzes weist.



   2. Verschluss nach Patentanspruch, dadurch gekennzeichnet, dass die Greiflasche in unbelastetem Zustand spitzwinklig vom Boden des Dichteinsatzes absteht.



   3. Verschluss nach Patentanspruch, dadurch gekennzeichnet, dass die Greiflasche   doppelwandig    und aus dem Dichteinsatz-Material herausgezogen ist, so dass sie mit dem Dichteinsatz ein Stück bildet
4. Verschluss nach Unteranspruch 3, dadurch gekennzeichnet, dass der Dichteinsatz unter der Greiflasche eine
Mulde aufweist, die sich gegen das mit dem Dichteinsatz ver   bundene    Ende der Lasche vertieft, wobei die untere Laschenwand in den Muldenboden und die obere Laschenwand in den der Mulde benachbarten   Abschmtt    des Bodens des Dichteinsatzes übergeht.



   Im Patentanspruch des Hauptpatentes wird ein   Behälter-    verschluss definiert, der einen beim erstmaligen Öffnen des Behälters zu entfernenden Dichteinsatz aus Folienmaterial aufweist, wobei in der Innenwand des Behälterrumpfes eine umlaufende Rille vorgesehen ist, in die ein passend gestalteter Rand am Aussenumfang des elastischen   Dichteinsatzes    radial nach aussen federnd einrastet.



   Dieser Dichteinsatz kann gemäss   Hauptnatent    mit einer Greifmulde versehen sein, die das Herausnehmen Ides Einsatzes erleichtert, ohne jedoch das Wiedereinsetzen zu erlauben. Diese letzte Eigenschaft erweist sich als notwendig wegen der Garantiefunktion, welche der Dichteinsatz nebst seiner Dichtfunktion auch hat.



   Das Herausnehmen des Einsatzes geschieht dadurch, dass die Fingerspitzen in die Greifmulde eingeführt werden und hernach ein Teil des Randes des elastischen   Dichtsnsatzes    in radialer Richtung aus der umlaufenden Rille gezogen wird, worauf der Einsatz auch auf dem Teil des Umfangs, welcher der befreiten Stelle gegenüberliegt, aus der Rille befreit und aus   rdem    Behälter herausgehoben werden kann.



   In der bekannten Ausgestaltung des Dichteinsatzes ist die Greifmulde aussermittig angeordnet und in Draufsicht etwa halbmondförmig mit innen gelegener, gerader Kante.



   Die bisher bekannte Greifmulde muss eine gewisse minimale Tiefe aufweisen, damit eine genügend grosse Eingriffsmöglichkeit für die Finger entsteht. Die Greifmulde ragt deshalb bei aufgesetztem Dichteinsatz in den zu   verschliessen den    Behälter hinein. Dies kann dazu führen, dass die Greifmulde beim Wegnehmen des Dichteinsatzes in Berührung mit dem Füllgut kommt und darin unerwünschte Spuren hinterlässt.



   Ein weiterer Nachteil der bisher bekannten Greifmulde ist darin zu erblicken, dass auf dem Dichteinsatz eine Anweisung über das Vorgehen beim Öffnen anzubringen ist, weil die Ausgestaltung der Greifmulde allein dem unerfahrenen Publikum nicht nahelegt, wie der Dichteinsatz am vorteilhaftesten zu entfernen sei.



   Der Erfindung liegt die Aufgabe zugrunde, einen Behäl   terverschiuss    zu schaffen, bei welchem der Dichteinsatz problemlos und ohne   spezielle    Anweisungen vom Behälter entfernt werden kann, ohne dass Teile des Dichteinsatzes ins Füllgut eintauchen.



   Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass sich an der Oberseite des Dichteinsatzes eine Greiflasche befindet. Diese Greiflasche ist vorzugsweise aussermittig angeordnet, wobei sich ihr mit dem Dichteinsatz verbundenes Ende aussen befindet, so dass ihr freies Ende gegen das Zentrum des Dichteinsatzes weist. In einer bevorzugten Ausführungsart steht die Greiflasche in unbelastetem Zustand spitz   vvinklig    von der Fläche des Dichteinsatzes ab. In einer weiteren Ausführungsart ist die Greiflasche doppelwandig und aus dem Dichteinsatzmaterial herausgezogen, z.B. vakuumgezogen, so dass sie mit dem Dichteinsatz ein Stück bildet.



   Im folgenden wird anhand der beiliegenden Zeichnung ein Ausführungsbeispiel der Erfindung näher beschrieben.



   Es zeigen:
Fig. 1 eine perspektivische Ansicht eines Dichteinsatzes und
Fig. 2 einen Teilschnitt durch den Dichteinsatz gemäss Fig. 1.



   In Fig. 1 ist der Dichteinsatz 1 dargestellt, welcher mit der Greiflasche 2 versehen ist. Der Dichteinsatz 1 und die Greiflasche 2 werden im selben Arbeitsgang aus dem Dichteinsatzmaterial vakuumgezogen, was eine kleine Mulde 3 bedingt, welche aber viel weniger tief in den Behälter hineinzuragen braucht, als die aus dem Hauptpatent bekannte Greifmulde.



  Die Greiflasche 2 ist doppelwandig. Sie steht im unbelasteten Zustand in einem spitzen Winkel   ix    von der Fläche des Dichteinsatzes 1 ab und ihr freies Ende weist gegen das Zentrum des Dichteinsatzes.



   Zum   Weniehmen    des Dichteinsatzes wird die Greiflasche 2 mit den Fingern gefasst und in Richtung des Pfeils C schräg nach oben gezogen. Dadurch erfährt der elastische Dichteinsatz 1 einerseits eine Kraft in der Richtung des Pfeils B, wodurch sich der Rand 4 auf einem Teil des Umfangs aus der Rille des   Behälterrumpfes      iöst    und andererseits eine Kraft in der Richtung des Pfeils A, wodurch auch der Rest des Randes 4 aus der Rille gelöst und der Dichteinsatz 1 aus dem Behälter gehoben wird.

 

   Das Wiedereinsetzen des Dichteinsatzes 1 dagegen ist praktisch unmöglich, da die Greiflasche 2 nicht die nötigen Angriffspunkte bietet, um den Dichteinsatz entgegen der Pfeilrichtung A in den Hals des Gefässes einzuschieben, was wegen der Form des Dichteinsatzes ohnehin ein äusserst schwieriges Unterfangen wäre, wie dies im Hauptpatent erläutert wird.



   Die Greiflasche weist den Vorteil auf, dass bei der Entfernung des Dichteinsatzes das Eintauchen eines Teiles des Dichteinsatzes ins Füllgut verhindert wird, da einerseits keine tiefe Greifmulde in den Behälter hineinragt und andererseits der Dichteinsatz beim Entfernen keine Bewegungen gegen das Gefässinnere ausführt.

   PATENT CLAIM
Container closure according to the patent claim of the main patent, characterized in that there is a gripping tab on the top of the sealing insert.



   SUBCLAIMS
1. Closure according to patent claim, characterized in that the gripping tab is arranged eccentrically and its end connected to the sealing insert is located on the outside, so that its free end faces the center of each sealing insert.



   2. Closure according to claim, characterized in that the gripping tab protrudes at an acute angle from the bottom of the sealing insert in the unloaded state.



   3. Closure according to claim, characterized in that the gripping tab is double-walled and pulled out of the sealing insert material so that it forms one piece with the sealing insert
4. Closure according to dependent claim 3, characterized in that the sealing insert under the gripping tab
Has trough which is recessed against the ver connected with the sealing insert end of the tab, the lower tab wall merging into the trough bottom and the upper tab wall into the section of the bottom of the sealing insert adjacent to the trough.



   In the claim of the main patent, a container closure is defined which has a sealing insert made of film material to be removed when the container is opened for the first time, a circumferential groove being provided in the inner wall of the container body, into which a suitably designed edge on the outer circumference of the elastic sealing insert radially follows resiliently engages on the outside.



   According to the main patent, this sealing insert can be provided with a gripping recess which makes it easier to remove the insert without, however, allowing it to be reinserted. This last property turns out to be necessary because of the guarantee function, which the sealing insert also has in addition to its sealing function.



   The insert is removed by inserting the fingertips into the gripping recess and then pulling part of the edge of the elastic sealing attachment in the radial direction out of the circumferential groove, whereupon the insert is also on the part of the circumference which is opposite the freed point, can be released from the groove and lifted out of the container.



   In the known embodiment of the sealing insert, the gripping trough is arranged eccentrically and in plan view is approximately crescent-shaped with a straight edge on the inside.



   The previously known gripping trough must have a certain minimum depth so that a sufficiently large possibility of engagement is created for the fingers. The gripping trough therefore protrudes into the container to be closed when the sealing insert is in place. This can have the result that the gripping trough comes into contact with the filling material when the sealing insert is removed and leaves undesired traces in it.



   Another disadvantage of the hitherto known recessed grip is that an instruction about the procedure for opening must be attached to the sealing insert, because the design of the recessed grip alone does not suggest to the inexperienced public how the sealing insert is most advantageously removed.



   The invention is based on the object of creating a container terverschiuss in which the sealing insert can be removed from the container easily and without special instructions, without parts of the sealing insert immersing in the product.



   This object is achieved according to the invention in that a gripping tab is located on the upper side of the sealing insert. This gripping tab is preferably arranged eccentrically, its end connected to the sealing insert being on the outside, so that its free end points towards the center of the sealing insert. In a preferred embodiment, the gripping tab protrudes from the surface of the sealing insert at a point in the unloaded state. In a further embodiment the gripping tab is double-walled and pulled out of the sealing insert material, e.g. vacuum-drawn so that it forms one piece with the sealing insert.



   An exemplary embodiment of the invention is described in more detail below with reference to the accompanying drawing.



   Show it:
Fig. 1 is a perspective view of a sealing insert and
FIG. 2 shows a partial section through the sealing insert according to FIG. 1.



   In FIG. 1, the sealing insert 1 is shown, which is provided with the gripping tab 2. The sealing insert 1 and the gripping tab 2 are vacuum-drawn from the sealing insert material in the same operation, which requires a small depression 3, which, however, needs to protrude much less deeply into the container than the gripping depression known from the main patent.



  The gripping tab 2 is double-walled. In the unloaded state, it protrudes from the surface of the sealing insert 1 at an acute angle ix and its free end points towards the center of the sealing insert.



   To turn the sealing insert, the gripping tab 2 is gripped with the fingers and pulled diagonally upwards in the direction of the arrow C. As a result, the elastic sealing insert 1 experiences, on the one hand, a force in the direction of arrow B, whereby the edge 4 is detached from the groove of the container body on part of the circumference and, on the other hand, a force in the direction of arrow A, which also causes the rest of the edge 4 is released from the groove and the sealing insert 1 is lifted out of the container.

 

   The reinsertion of the sealing insert 1, on the other hand, is practically impossible, since the gripping tab 2 does not offer the necessary points of application to push the sealing insert into the neck of the vessel against the direction of arrow A, which would be an extremely difficult undertaking anyway because of the shape of the sealing insert, as shown in Main patent is explained.



   The gripping tab has the advantage that when the sealing insert is removed, part of the sealing insert is prevented from dipping into the product, since on the one hand there is no deep gripping recess protruding into the container and on the other hand the sealing insert does not move against the inside of the vessel when it is removed.

Claims

An exemplary embodiment of the invention is described in more detail below with reference to the accompanying drawing.

Show it: Fig. 1 is a perspective view of a sealing insert and FIG. 2 shows a partial section through the sealing insert according to FIG. 1.

In FIG. 1, the sealing insert 1 is shown, which is provided with the gripping tab 2. The sealing insert 1 and the gripping tab 2 are vacuum-drawn from the sealing insert material in the same operation, which requires a small depression 3, which, however, needs to protrude much less deeply into the container than the gripping depression known from the main patent.

The gripping tab 2 is double-walled. In the unloaded state, it protrudes from the surface of the sealing insert 1 at an acute angle ix and its free end points towards the center of the sealing insert.
