Abstract
On the top of a mould above each of several cavities for moulding sticks of lipstick, is disposed a first tubular element of a cup comprising an external device for catch-engagement with a second tubular element of the cup, which second tubular element is intended to cooperate with the rest of the case, namely a shell with its internal liner and sleeve. The composition of the lipstick is cast through the first tubular element portion to fill the cavity and at least partly fill the internal space of the first tubular element. After solidification, the case is brought above each cavity to mount the second tubular element in the upper portion of the case until the second tubular element is catch-engaged on the first tubular element. The unit thus formed is extracted from the mould by upward translation and the lipstick thus cast is retracted into its case.
