Abstract
A dispenser for drawing toothpaste from a squeeze-tube container and applying it to the top of a toothbrush with a vacuum pump of piston-cylinder construction which is so operated that the pump draws the toothpaste out of the squeeze-tube container when the toothbrush is pushed into the dispenser and discharges the same when the toothbrush is withdrawn. The toothpaste is pumped through a passage which is provided with an inlet valve which operates in cooperation with an elastic adapter used for mounting and sealing the neck portion of the squeeze-tube container, an outlet valve which operates in cooperation with a port formed in the cylinder, and an elastic discharge nozzle which opens when the toothpaste is being pumped and closes by its own resiliency when the toothpaste is being drawn out of the squeeze-tube container. The amount of toothpaste supplied each time by the dispenser can be adjustably predetermined as desired.
