Patent ID: 8685309

Claim:
A method for making a personal care product, the method comprising: (a) providing a mold suitable for forming a container during a blow mold process; (b) placing a container preform in the mold, the container preform comprising (i) an extensible polymeric preform and (ii) an elastic member surrounding at least a portion of the polymeric preform, the elastic member being stretchable axially and radially and being constructed of an elastically extensible material that permits the transfer of infrared radiation through at least a portion of the elastic member; (c) heating the container preform with infrared radiation to at least the glass transition temperature of the polymeric preform; (d) expanding the polymeric preform during a blow molding process to form a collapsible bag comprising an internal storage space suitable for receiving a personal care composition, whereupon expanding the polymeric preform causes the elastic member to be stretched axially and radially thereby generating potential energy; (e) permitting the elastic member to contract axially and radially to collapse the collapsible bag; (f) providing an actuatable valve member for opening and closing a flow path from the collapsible bag to an external environment; (g) charging the collapsed bag with a personal care composition; and (h) wherein the personal care composition includes a skin care composition comprising an active ingredient selected from the group consisting of zinc oxide, petrolatum, white petrolatum, mineral oil, cod liver oil, lanolin, dimethicone, hard fat, vitamin A, allantoin, calamine, kaolin, glycerin, and colloidal oatmeal, and combinations of these.
