ABSTRACT:
A process for shaping an end of a solid cosmetic stick such as a deodorant or antiperspirant. The process includes the steps of filling a package body with a molten cosmetic composition, solidifying the composition into stick form, heating a mold or package cap, elevating the stick to extend the package body opening, and contacting an end portion of the stick with the heated die or cap. A pattern such as a trademark or logo may be molded through this process onto the end portion of the stick.
