Patent

CA 2205537

A stack (31) of cup-shaped containers (2,4,6) coaxially inserted one inside another is described, each with a side wall (32) on one end of which a base (33) is arranged, and on the other end a flange (1), wherein the container (2,4,6) is composed of a flexible material and the flange (1) is substantially stiffer than the side wall (32) and the base (33). In order to make such a stack (31) more easy to manufacture and to take apart, it is provided according to the invention that apart from the outermost cup- shaped container (4), each inner container (2) is partially radially folded, and that the degree of folding gradually increases towards the innermost cup-shaped container (2).

L'invention concerne une pile (31) de récipients (2, 4, 6) en forme de gobelet, encastrés de façon coaxiale, chacun de ces récipients présentant une paroi latérale (32), avec un fond (33) à une extrémité et un bord (1) à l'autre extrémité. Ce récipient (2, 4, 6) est réalisé dans un matériau flexible. Le bord (1) est nettement plus rigide que la paroi latérale (32) et le fond (33). L'invention vise à faciliter la fabrication de cette pile (31) et son désassemblage. A cet effet, outre le récipient en forme de gobelet situé le plus à l'extérieur, chaque récipient intérieur (2) est plié partiellement dans le sens radial, et le degré de pliage augmente progressivement vers le récipient en forme de gobelet situé le plus à l'intérieur.
