ABSTRACT:
An applicator for dispensing a product that flows under pressure. The applicator has an exterior top surface, an exterior sidewall, and a base. The applicator has a chamber which constitutes a reservoir for holding the product to be dispensed. The reservoir has a top wall, a bottom wall and a side wall. The applicator has an orifice for dispensing product, and the orifice connects the top surface to the top wall. The chamber has a disk capable of traveling through the chamber forcing product through the orifice as it travels through the chamber. The disk has a product contact surface that contacts a major portion of the top surface when the travel of the disk is complete so that product remaining in the chamber is minimized.
