CA 2642845

The invention concerns a method for making a container (1) comprising two or more compartments, said method including the following steps: a first step of heat sealing (S1) performed between two sheets (11, 112) so as to form the periphery of the container and performed at a temperature such that said seal (S1) is resistant to a predetermined stress, while providing filling orifices (12), a second step of heat sealing (S2) performed to form at least one separation between the compartments (13) and performed at a second temperature lower than said first temperature and such that said seal (S2) is breakable by said stress, a third step of filling said compartments (13). The invention is characterized in that after said first sealing step, the two sealed sheets (11, 112) are arranged in a mold (2, 2') whose shape they match under the pressure of a gas.

L'invention concerne un procédé de fabrication d'un contenant (1) du type comprenant deux ou plusieurs compartiments, ledit procédé comportant les étapes suivantes : une première étape de soudure thermique (Sl) réalisée entre deux feuilles (111, 112) de manière à former la périphérie du contenant et réalisée à une première température telle que ladite soudure (Sl) soit résistante à une sollicitation prédéterminée, tout en ménageant des orifices de remplissage (12), une deuxième étape de soudure thermique (S2) réalisée pour former au moins une séparation entre des compartiments (13) et réalisée à une seconde température inférieure à ladite première température et telle que ladite soudure (S2) soit fragile à ladite sollicitation, une troisième étape de remplissage desdits compartiments (13). L'invention consiste en ce qu'après ladite première étape de soudure, lesdites deux feuilles soudées (111, 112) sont disposées dans un moule (2, 2') dont elles épousent la forme sous la pression d'un gaz.
