ABSTRACT:
The present invention in one embodiment is a device and method for flattening bottle caps from beverage containers. In a preferred embodiment of the invention, the bottle cap flattener includes a bottle cap positioner, a bottle cap holder, a bottle cap flattening tool, a motor and a positioning jig. The bottle cap positioner precisely locates a bottle cap so that the bottle cap flattening tool can interact with the bottle cap to flatten the bottle cap. The bottle cap positioner preferably includes a rotatable disk that is rotated by the motor. The bottle cap flattening tool applies pressure to a bottle cap through a tip to force the outer portion of the bottle cap into a flattened configuration along with the central portion of the bottle cap. The bottle cap holder applies force to a bottle cap located on the bottle cap positioner to hold the bottle cap in a precise relationship with the bottle cap positioner. Where the bottle cap positioner includes a rotating disk, the bottle cap holder applies force to a bottle cap located on the disk to hold the bottle cap on the disk. The positioning jig precisely locates the bottle cap on the friction surface of the disk so that the bottle cap can be acted on by the bottle cap flattening tool.
