Abstract
An applicator (33) to deliver viscous liquids such as cream, mayonnaise or mustard. The applicator (33) includes a cylinder assembly (25) which receives a piston (4). The cylinder assembly (25) separates a pair of chambers (26, 27). The piston (4) includes a one-way valve (3) which is resiliently deflectable from apertures (28) in the piston to provide for the flow of liquid from the chamber (26) to the chamber (25). An inlet extends to the chamber (26) while an outlet valve (1) communicates with the chamber (24). This arrangement minimizes hand pressure required by an operator to manipulate the applicator (30) in delivering the viscous liquid.
