ABSTRACT:
A compressor for cans and the like. First and second plates are pivotally secured to each other for movement between open and closed positions, each of said plates including a planar bearing surface defining a compression area. In a preferred embodiment, the plates are non-parallel in the open position and generally parallel in the closed position with the location of the pivot connection being offset from the planes of both bearing surfaces. This offset facilitates ejection of the compressed material while reducing the forces which tend to prematurely eject the material to be compressed.
