Title
(EN) THERMOPLASTIC CONTAINER OPENED BY PARTIALLY PEELING BACK A MULTI-LAYERED TOP WHICH HAS BEEN HEAT-SEALED TO ITS EDGE, AND FILM FOR MULTI-LAYER TOPS

Abstract
(EN)
The invention relates to a multi-layered thermoplastic container (1) opened by the partial peeling back of a multi-layer top (6) which has been heat-sealed onto the edge (3) of the container (1), said container including a peeling tab (7). The peeling tab (7) has a scalloping (15) cut into its edge (3) in such a way as to delimit a grip cavity (16) open onto the sides of the top (6) and of the edge (3). Said grip cavity faces the area where the internal sheet (9) of the top (6) and the internal layer (4) of the container (1) meet, the intermediary sheet (10) having a tearing edge enabling the internal sheet (9) to be torn.
(FR)
L'invention concerne un récipient thermoplastique multicouches (1) à ouverture par pelage partiel d'un couvercle multicouche (6) thermosoudé sur le rebord (3) du récipient (1) comprenant une amorce de pelage (7). L'amorce de pelage (7) comprend une échancrure (15) ménagée dans le rebord (3) de façon à délimiter une cavité de préhension (16) ouverte sur les bords du couvercle (6) et du rebord (3) et, en face de la zone de jonction entre la feuille interne (9) du couvercle (6) et la couche interne (4) du récipient (1), la feuille intermédiaire (10) présente une arête de déchirement facilitant la déchirure de la feuille interne (9).
