ABSTRACT:
Segmented cosmetic articles are made by positioning an empty pan at the bottom of a sleeve having interior partitions forming separate compartments or chambers extending longitudinally the full extent of the sleeve, with each compartment being adapted to receive a corresponding charge of loose powder (each preferably of different color) through the end of the sleeve distal with respect to the pan. A ram or piston assembly havin solid segments conforming in shape to each separate chamber then is slidably received within the sleeve through the opening through which loose powder is admitted, and telescopically advanced relative to the sleeve toward the pan at other end thereof sufficient to pre-press or partially compress the powder charge into the pan. By this action, all segments of powder corresponding to the charge in each chamber of each sleeve, respectively, are partially compressed simultaneously. The sleeve is then moved telescopically relative to the piston assembly away from the pan and the pre-pressed segments therein thereby permitting the pan to be subsequently engaged by a second piston assembly having a shape congruent to the shape of the pan mouth effective to finally compress the prepressed multi-colored segements therein.
