Abstract
Abstract A can crusher for compacting cans, such as aluminum soft drink cans, into a substantially flat configuration for storage, recycling or disposal. The can crusher includes a base with opposing flanges and a handle which rotates about the flanges. The handle includes an extending crimping member which compresses the center of the can downwardly, and also forces the ends of the can inwardly. The handle also includes a flat surface which then flattens and rotates the ends of the can towards a mid-portion of the can into a substantially flat configuration. The first action of the extending crimping member against the can and the second action of the flat surface against the can crush the can into a substantially flat can which is environmentally and ecologically useful in recycling processes. The crushed can consumes less space in recycling operations or disposal, and environmentally and ecologically presents itself in a more pleasing manner for recycling or disposal.

Claim 1
Independent Claim
231 words
Can crusher for crushing a can including two ends comprising: a. a flat base with a curved area for retaining the can and with two opposing spaced flanges extending vertically upward from a rear portion of said base, two spaced can support members connected between end corners of said flat base and said opposing spaced flanges and opposing pivot pin holes in said flanges; b. a U-shaped handle including spaced opposing legs and an end member connected to said opposing legs, a vertical end member secured to another end of said opposing legs, an extending crimping member with a rounded end extending rearwardly from a rear of said end member, and a lower flat surface extending between said vertical end member and a lower portion of each of said downwardly extending legs and in a lower plane with respect to a upper plane of said extending crimping member and substantially 180° opposite said extending crimping member; and, c. pivot pins rotationally securing opposing ends of said vertical end member of said U-shaped handle to said pivot pin holes of said spaced opposing flanges whereby first, said extending crimping member first rotates the ends of the can towards each other and simultaneously pressing the center of the can and second, said flat surface folds the ends of the can about the can when said U-shaped handle is rotated about said pivot pins.
