Abstract
A dispensing container is provided for delivery of viscous flowable materials such as toothpaste. The container includes a cylindrical upper body for containing the viscous flowable material and is fitted with an orifice for allowing egress thereof. At a lower end of this body is fitted a piston sealingly slidable within the upper body. The piston is formed from a diaphragm and a skirt of circumferentially concave form surrounding the diaphragm and sealingly slideable against an inner wall of the upper body. Within the piston is a cavity downwardly open. A cylindrical lower body is received telescopically within the cylindrical upper body. A boss portion is formed on top of the lower body and extends into the piston cavity to establish a snug, frictional fit. When the container is exhausted of viscous flowable material, the upper body can be discarded and a refill of similar construction can be mounted on the reusable cylindrical lower body.
