Two layer lid

Couvercle à deux couches

Abstract

The lid element (1) for closure of a container (7) consists of two layers (2, 3) joined to one another by a cold-sealable material (4) whose adhesion is weaker than the adhesion of a hot-sealable material on the other side of the inner layer.
Die Erfindung betrifft ein deckelförmig ausgestanztes Element (1) zum Verschließen von Behältern (7) bestehend aus einer ersten Lage (2) und einer zweiten inneren Lage (3), welche an ihrer dem Behälter zugewandten Seite mit einer heißsiegelbaren Schicht (5) versehen ist. Erfindungsgemäß werden die Lagen (2, 3) über ihre einander zugewandten Oberflächenseiten (2', 3') durch eine kaltsiegelnde Schicht (4) miteinander verbunden, wobei die Verbundhaftung zwischen den Lagen (2, 3) niedriger ist als jene zwischen der inneren Lage (3) und dem Behälterrand (8). An der inneren Lage (3) können Sollbruchstellen (10) vorgesehen sein, welche durch Abschälen der äußeren Lage (2) freigelegt werden. Wird in dem Behälter (7) beispielsweise Packungsgut, welches sich zum Erwärmen in Mikrowellenöfen eignet, gelagert, so können die beim Erwärmen entstehenden Dämpfe durch die Sollbruchstellen (10) entweichen.
