Cosmetic product

Abstract

A package cosmetic product includes container structure that has application surface structure at one end, dispensing structure at the opposite end that is movable towards the application surface structure, and gelled cosmetic material disposed in the container between the dispensing structure and the application surface structure. The application surface structure has an application surface with an array of dispensing ports, each port being at the end of and in direct communication with an elongated distribution passage. The array of distribution passages is defined by an interconnected array of elongated divider webs shaped to provide each distribution passage with a flared entrance port and a relieved dispensing port region at the application surface. Movement of the dispensing structure towards the application surface structure extrudes the gelled cosmetic material through the array of elongated distribution passages to present a metered quantity of the gelled cosmetic material at the application surface for application to the skin surface to be treated.
