Abstract
The device described here is for manufacturing a stack of cup-shaped containers coaxially inserted inside another, each with a side wall, on one end of which a base is arranged, and on the other end a flange (1), wherein the container is composed of a flexible material and the flange (1) is substantially stiffer than the side wall and the base. In order that cup-shaped containers which, from a geometrical viewpoint can only be stacked one inside another in small numbers, can be combined to form longer stacks of at least 20 containers it is provided according to the invention that in the end plate (9) of a gas-tight housing (8) there is arranged, in a driveable manner, at least one cup-shaped cavity (16) intermittently moveable in the longitudinal direction (12) of the latter up to a maximum lift (h) which is equal to the maximum height of the flange area of the container stack, that the aperture of the cavity (16) is configured and arranged for level receipt and installation of the flange (1) of the first, outer container of the stack, and in the initial position (I) before the first movement is arranged in the area of the end plate (9), accessible from outside the housing (8), whi…
