Abstract

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).
