Abstract

A canned material compressing and liquid extracting device includes a pair of elongated lower and upper handles and a hinge pivotally attaching adjacent respective one ends of the handles together permitting the handles to be moved toward and away from each other between a closed position and an opened position. The device also includes a land portion mounted on the lower handle for seating a container which has an open top end and encloses a material to be compressed and a piston member pivotally mounted to the upper handle for insertion into the open top end of the container so as to overlie a severed lid of the container for applying a force on the severed lid sufficient to compress the material in the container and extract liquid therefrom as the upper and lower handles are moved relative to one another from the opened position toward the closed position. The device further includes a linkage extending between and connected with the piston member and the one end of the lower handle to cause pivoting of piston relative to the upper handle in a direction opposite to the direction of pivoting of the upper handle relative to the lower handle as the handles are moved toward and away from one another so as to maintain the piston in a predetermined alignment with the container for facilitating uniform compressing of the material in the container.
