Cosmetic Applicators Containing Heating Elements

摘要

Product applicators that are separable from a product reservoir and that heat a portion of product. A product applicator fitted with an electronic heating element capable of connecting to a low voltage power source. Most of the electric circuitry is incorporated into a circuit subassembly, for example a flexible substrate with printed-on circuit. The preferred heating element is a flexible heater. Heat emanates from the surface of the separable applicator so that the product that is closest to the applicator surface is heated prior to and/or during application.
