Apparatus and method for manufacturing cosmetic products
First Claim
1. A multiple cavity mold for forming a plurality of cosmetic lipstick products comprised of a thermoplastic material selected from the group consisting of a polyalkylene having 2 to 8 carbons, polyamide, styrenic, polyacetal, polycarbonate, polyacrylate, polyester, cellulosic, or mixtures thereof, wherein the inner surface of said mold has been halogenated with a plasma treatment gas selected from the group consisting of ethylene tetrafluoride, fluoroethane, silicon fluoride, fluorine, methyl fluoride, or mixtures thereof, wherein said cavities are sized and shaped so as to form lipstick bullets, comprising a base having a substantially hollow interior chamber and a plurality of receptacles depending from said base and extending into said interior chamber thereof, each of said receptacles having an inner surface, which forms a cavity for forming at least a major portion of a cosmetic lipstick product, and an outer surface, which is exposed to said interior chamber of said base;
- and accessing means comprising at least one opening in a wall of said base for allowing coolant to enter said interior chamber of said base and to contact said outer surfaces of said receptacles, and wherein said mold further comprises a cap section removably mounted on said base, said cap section having a plurality of projections extending outwardly therefrom, each of said projections defining a bore which is in alignment with a corresponding one of said cavities to form a portion of a corresponding cosmetic product.

12. A method of manufacturing a plurality of cosmetic products using a multiple cavity mold comprised of a thermoplastic material selected from the group consisting of a polyalkylene having 2 to 8 carbons, polyamide, styrenic, polyacetal, polycarbonate, polyacrylate, polyester, cellulosic, or mixtures thereof, wherein the inner surface of said mold has been halogenated with a plasma treatment gas selected from the group consisting of ethylene tetrafluoride, fluoroethane, silicon fluoride, fluorine, methyl fluoride, or mixtures thereof, said method comprising the steps of:
-
(i) providing a base with a substantially hollow interior chamber and a plurality of receptacles depending from said base and extending into said interior chamber, and a cap section with projections, (ii) providing accessing means comprising an opening in a wall of said base, (iii) placing the cap section on the base and filling each cavity of the mold with a quantity of cosmetic melt, (iv) flowing a coolant through the accessing means into the interior chamber of the base to contact the outer surfaces of the receptacles to thereby solidify the cosmetic melts and form the products; and (v) removing said products from the mold. - View Dependent Claims (13, 14, 15, 16, 17)
