Abstract
A toothpaste dispenser having an upper chamber and an inlet port connected for receiving toothpaste and a lower chamber and an outlet port connected for dispensing toothpaste. Suction is created to draw toothpaste into the inlet port, and then forced through the outlet port during actuation. Initiating operation of the suction pulls toothpaste into an upper chamber, and a plunger for expelling the toothpaste from the chamber is operatively connected to the outflow ball check valve for intermittently blocking the flow of toothpaste into and from the toothpaste dispenser. The toothpaste dispenser utilizes ball check valves and two return springs operatively connected to the ball check valves. The toothpaste dispenser actuation has a plunger and also has a portion size adjustment device connected to the plunger for modifying the amount of toothpaste dispensed from the toothpaste dispenser.
