  • Cosmetic applicator, precursor and related manufacturing method
    Publication number: 20120305556
    Abstract: A cosmetic applicator, such as a gel puff, includes a body enclosing a gel. The body lacks any gate mark as the result of being manufactured by a process including providing a base layer in a mold to form a cavity, providing the gel material in the cavity, and providing a removable cover for covering an exposed surface of the gel material so as to fully enclose it and form a precursor. The precursor is then removed from the mold, the cover removed, and a surface layer is applied to the exposed surface of the gel material to complete the applicator and process.
