A viscous product dispenser is described which comprises a tubular container body adapted to hold product, a take-up piston at the lower end of the body which decreases the internal volume of the container as product is dispensed from the container, and a bulk liquid pump dispenser at the upper portion of the container body having a product inlet extending into the container body and a finger depressible, spring-biased piston/cylinder pumping mechanism. The pumping mechanism of the bulk liquid pump dispenser has a product outlet conduit which is parallel and coaxial to the outlet axis of the product inlet and the center of the piston. The piston/cylinder pumping mechanism is of substantially less cross-sectional area than the internal diameter of the container body. The take-up piston can have a central depression to accommodate the lower portions of the housing of the pump dispenser when the piston reaches its uppermost location when the container is nearly fully evacuated of product. Transverse slot means cut downwardly in the upper surface of the piston extend radially outwardly from the central depression to the sides of the piston to provide a means to bleed or vent oft unwanted air entrapped in product which lies in the central depression.
