[origin: EP0078471A2] 1. A squeezable container (1), in particular an expendable or non-expendable package, for pasty, liquid or powdery filling matter, said container being made of stiff, pliant and flat material formed by arching or shaping a base (3) and simultaneously raising and arching two side portions (5) and tightly connecting the mutually opposed side edges or flanges (6) of the side portions (5), after which the filling matter is filled in and a portion left open therefor is closed, the superposed flanges or edges (6) not being connected at at least one point in order to form at least one flat passage (7), said passage (7) ending in an outlet the walls (9) of which lie flat upon one another in the region of the passage (7) and through the prestressing of the curved material having increased resistance against arching away from one another and being urged against each other in a manner similar to a lip seal and the opened outlet being at least largely self-closing, characterized in that the container (1) is made from a single, flat cut-out (2) of material, wherein a centre portion (3) connecting the two side portions (5) is contoured as a base, that the material is coated cardboard and that the passage (7) flatly traversing the edge (6) of the container (1) ends in a tongue (8) which is removable by being torn or cut off and is closed prior to use, the passage (7) remaining largely closed even after the tongue (8) has been removed.
