ABSTRACT:
In a manually operated dispenser especially suited for striped toothpaste products and the like the reciprocable pumping piston is provided with a concave, product-engaging face that gently, yet forcibly, directs the product in a smooth, laminar flow out of the pump chamber and into the discharge spout when the piston is depressed through a pumping stroke so that stripes in the ribbon of toothpaste issuing from the spout are well defined and maintained in an aesthetically pleasing manner. The cooperating floating takeup piston at the opposite end of the chamber from the pumping piston is provided with a convex dome that becomes complementally received within the concavity of the pumping piston when the contents of the dispenser are nearly depleted, thereby maximizing the degree to which the dispenser is emptied.
