ABSTRACT:
The present invention is directed to a metered side dispensing cap system for containers such as tubes and the like. It includes a chamber unit having an inlet opening in the bottom for flow of a material from a squeezable container into the chamber. The chamber unit has an outlet opening on a sidewall located near the bottom for dispensing material from the chamber in a metered amount. A one-way valve located in the inlet opening on the bottom of the chamber unit permits flow of material through that opening and prevents backflow of material. A piston mechanism moves upwardly and downwardly within the chamber. The piston mechanism is capable of upward movement by material entering the chamber unit when a squeezable container is squeezed and material enters the chamber unit through its inlet opening. The piston is capable of downward movement when its wide top is pushed downward, so as to dispense material through the sidewall outlet opening of the chamber unit. The system is attachable to an open neck of a squeezable container.
