Abstract

L'invention concerne un dispositif de fermeture d'un emballage composite rempli d'une matière de remplissage fluide incompressible et formé d'une enveloppe cylindrique (P). Le dispositif peut être utilisé dans une opération cadencée et comporte une pluralité de stations de traitement (1, 6, 7, 8, 9) disposée l'une après l'autre, une station de traitement (8) comportant un dispositif de pression (12) permettant de presser les projections de pliage (11), créées lors de la fermeture, contre la surface de fond de l'emballage (P). Le dispositif de pression (12) est disposé de façon mobile sensiblement perpendiculairement à la surface de fond. Selon l'invention, pour garantir une liaison sûre et stable des projections de pliage (11), formant une partie du fond de l'emballage, avec le fond de l'emballage et éviter de façon fiable d'endommager également les couches stratifiées individuelles de l'emballage composite, le dispositif de pression (12) comporte au moins un dispositif d'amortissement (18, 18') ou au moins un élément d'amortissement (18''). En outre, l'invention concerne une utilisation du dispositif susmentionné pour emballer des produits alimentaires, en particulier des aliments conditionnés de façon aseptique.
