ABSTRACT:
An improved can crusher device including a coil spring, forming a chamber, attached at its upper end to a substantially flat disk. When force is applied to the disk a can placed within the chamber is crushed. Preferrably, the coil spring is flared progressively toward its lower end to confer stability to the device during the can crushing operation and promote optimal can compression. The preferred disk has a peripheral edge and annular wall on its lower surface which work with the coil spring to hold the can in place. One preferred embodiment has gaps in the annular wall to release accumulated air pressure. When not in use, the can crusher may be compacted for storage or transportation with holders positioned through the disk and under the coil. The device is light-weight, yet durable, promotes quick, efficient can crushing, and enhances the economic virtues associated with recycling empty cans.
