ABSTRACT:
A process for manufacturing a wax-like cosmetic stick having an improved contour on its upper surface, by filling at the open bottom of the case with the stick material in a molten state, the case having a cap which provides the contour, allowing the stick to partially solidify, while maintaining the upper surface molten, placing a push-up device in the bottom of the case, seating the push-up device against the molten upper surface, said push-up being designed to allow substantially all of the air to escape during seating, then allowing final solidification of the stick.
