Abstract
A method of making a personal care product that is capable of dispensing a composition onto a surface in the form of a film without the use of an additional applicator. The method includes providing a collapsible bag at least partially surrounded by an elastically deformable member and, optionally, an outer container body. Potential energy is generated by stretching the elastically deformable member, which is used to dispense the composition in lieu of a propellant or pump. The personal care composition may be a skin care composition, an antifungal, or an enzyme inhibiting composition.
Claims18
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.
