The liquid-tight container comprises a sheet (34) fixed for a liquid-tight connection surrounding an area of said sheet to the internal face of a wall (1) of the container. A tongue (5) is provided in the wall (1), adjacent to said area, and is partly welded to the sheet (34) so as to provide for its breakage and to have acces to the content of the container. Alternatively, said liquid-tight container comprises 4 superimposed sheets (1, 2, 3, 4). The sheet (1) has a precut tongue (5) welded (13) to a portion of the sheet (2). A channel (10) is provided between the sheets (2 and 3) and acts as a valve between the inside and the outside of the liquid-tight container formed between the sheets (1, 4). A cut-out (9a) of the sheets (2, 3) provides for the communication of the channel (10) with the inside of the container formed between the sheets (1, 4). By pulling the tongue (5), the wall of the channel (10) formed by the sheet (2) is torn open, and the channel communicates with the outside.
Cette enceinte étanche comporte quatre feuilles superposées (1,2,3,4). La feuille (1) comporte une languette prédécoupée (5) soudée (13) â une portion de la feuille (2). Un canal (10) est ménagé entre ces feuilles (2) et (3) et sert de valve entre l'intérieur et l'extérieur de l'enceinte étanche formée entre les feuilles (1, 4). Une découpe (9a) des feuilles (2, 3) permet de mettre le canal (10) en communication avec l'intérieur de l'enceinte formée entre les feuilles (1,4). En tirant la languette (5) on déchire la paroi du canal (10) formé par la feuille (2) et on met ce canal en communication avec l'extérieur.
