Abstract
An applicator ( ) to deliver viscous liquids such as cream, mayonnaise or mustard. The applicator ( ) includes a cylinder assembly ( ) which receives a piston ( ). The cylinder assembly ( ) separates a pair of chambers ( ). The piston ( ) includes a one-way valve ( ) which is resiliently deflectable from apertures ( ) in the piston to provide for the flow of liquid from the chamber ( ) to the chamber ( ). An inlet extends to the chamber ( ) while an outlet valve ( ) communicates with the chamber ( ). This arrangement minimizes hand pressure required by an operator to manipulate the applicator ( ) in delivering the viscous liquid.
