Abstract
(DE)
Die Abdeckkappe (13) weist eine Deckfolie (14) auf, die als becherförmiges Formteil ausgebildet und an das eine Ende des Behälters (10) angeklebt ist. Unter die Stirnwand (14a) der Deckfolie (14) ist mit einer Haftschicht (15) eine Berstfolie (16) geklebt, die die Öffnungsfläche (11) des Behälters (10) bedeckt. In der Deckfolie (14) sind Schlitze (17) ausgebildet. Bei einem Druckaufbau im Behälter (10) reißt die Berstfolie (16) entlang der Schlitze (17) der Deckfolie auf. Dabei bilden sich Lappen aus, die sich außen an den Behälter (10) anlegen, jedoch bleibend mit der Abdeckkappe (13) verbunden sind.
(EN)
The invention concerns a covering cap (13) comprising a cover foil (14) which takes the form of a cup-shaped moulded part and to which one end of the container (10) is affixed. Bonded below the end face (14a) of the cover foil (14) by means of a layer of adhesive (15) is a breakable foil (16) which covers the opening area (11) of the container (10). Slits (17) are formed in the cover foil (14). When pressure builds up in the container (10), the breakable foil (16) tears along the slits (17) in the cover foil. At the same time, tabs form and lie against the outside of the container (10) but remain connected to the covering cap (13).
(FR)
Le capuchon de fermeture (13) comporte une pellicule de recouvrement (14) se présentant sous forme de pièce moulée cupuliforme, assemblée par collage à une extrémité du récipient (10). Une pellicule destinée à la rupture (16) qui recouvre la surface d'ouverture (11) du récipient (10) est collée sous la paroi d'about (14a) de la pellicule de couverture (14), à l'aide d'une couche adhésive (15). Des fentes (17) sont pratiquées dans la pellicule de couverture (14). Lorsque la pression augmente dans le récipient (10), la pellicule destinée à la rupture (16) se déchire le long des fentes (17) de la pellicule de couverture, ce qui donne lieu à la formation de languettes qui s'appuient à l'extérieur sur le récipient (10), tout en restant rattachées au capuchon de fermeture (13).
