Abstract

Patente de Invenção: <B>"MEMBRANA DE VEDAçãO"<D>. Membrana de vedação para recipientes, contendo uma folha externa e uma folha interna e uma camada de ligação disposta entre as duas folhas e uma zona de costura de selagem. Dentro da zona de costura de selagem, entre a folha externa e a folha interna, está disposto pelo menos um espaço intermediário livre de camada de ligação, e, dentro dos limites do espaço intermediário livre de camada de ligação, a folha externa e a folha interna apresentam, cada uma, pelo menos uma abertura, e, no espaço intermediário livre de camada de ligação, entre a folha externa e a folha interna, está disposto um estoque de um material que se amolece por calor. As aberturas da folha interna e as aberturas da folha externa estão inicialmente em ligação uma com as outras e possibilitam a passagem de um fluido, tal como um gás, a partir do espaço interno do recipiente para a atmosfera do ambiente. Por ocasião de uma pressurização por calor de membrana de vedação, por exemplo, quando de um processo de esterlização do recipiente dotado com a membrana de vedação, por um amolecimento do material que se amolece por calor, as aberturas na folha interna e na folha externa são fechadas.
