ABSTRACT:
Disclosed is a tool for molding food patties in the form of a cylinder having an open bottom. A piston slidably disposed within the cylinder has a pushrod projecting upwardly out of the cylinder and is guided for vertical reciprocating movements. A handle is fastened to the top of the pushrod and resilient means is provided for biasing the handle and the attached piston upwardly. An elastic closure diaphragm is secured across the open bottom of the cylinder to yield and deform into engagement with the interior surface of the cylinder and the under surface of the piston when the tool is pressed downwardly on a quantity of plastic food to mold the same. The diaphragm returns to its original shape to automatically eject the molded pattie when the tool is lifted.
