ABSTRACT:
A dispenser, particularly useful as a pump for viscous material such as toothpaste has, in one embodiment, a body, a spout at the top of the body, a tube disposed vertically within the body aligned to register with the spout, a piston surrounding the tube below the top and a spring exerting continuous downward force on the piston so that the material to be dispensed which is located under the piston is forced up through the tube and out the spout when the spout is open. The spout may be of the turret type. Another embodiment comprises the same basic design, but it adapted to receive a refill container of the material. This Abstract shall not be construed to limit the scope of the specification, drawings or claims.
