ABSTRACT:
A dispenser for use in dispensing a semi-solid material such as a paste, gel, ointment or the like, from a deformable tube, a particular application being for the dispensing of toothpaste. The product tube is screwed to the dispenser via the threaded throat and bears on one of two non-return valves to create an airtight seal. The tube is squeezed to prime the dispenser and fill the cavity. When a plunger assembly is pressed inward against a spring, product is displaced through the non-return valves and a dispensing nozzle. On release of plunger, the spring returns plunger to its original position and by vacuum action displaces an equivalent amount of product from the tube to replenish product in the dispenser cavity. The dispenser preferably has side flanges and projecting pins for the storage of toothbrushes.
