[0068] FIG. 2 shows the outer sleeve in a closed and assembled state.

[0069] FIG. 3 shows the inner sleeve.

[0070] FIG. 4 shows an exploded view of the inner sleeve showing the bottom that can be clamped in the bottom of the cylinder wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0072] The body care or cosmetic stick 10 comprises an inner sleeve 12 and an outer sleeve 14, wherein the inner sleeve 12 can be inserted into the outer sleeve 14 from below, for example. The outer sleeve 14 can be made of three parts and comprise a cap 20, a central part 22 and a lower part 24 (cf. FIG. 1). These three parts can be sticked together and then form the outer sleeve 14 as shown in FIG. 2. The inner sleeve 12 can be a cylindrical paper sleeve wherein a circular cardboard bottom 28 can be clamped in at the bottom of the cylinder wall 26 (cf. FIGS. 3 and 4). The inner sleeve can then be filled with the body care or cosmetic mass 30 and inserted into the outer sleeve 14 and clamped there, as shown in FIG. 5. Thus, the inner sleeve outer top edge 16 can be slightly broader than the outer sleeve inner top edge 18 to prevent the inner sleeve 12 from being pushed out of the outer sleeve 14 when the user pushes against the bottom 28 with a finger from below to press the body care or cosmetic mass 30 upwards within the inner sleeve 12.

[0073] The features of the invention disclosed in the present description, in the drawings as well as in the claims both individually and in any combination may be essential to the realisation of the various embodiments of the invention. The invention is not limited to the described embodiments. It may be varied to the extent as falls into the scope of the invention, taking into account the knowledge of one skilled in the art.
