ABSTRACT:
A combination can crushing and retrieving device having a circular or tubular housing containing a plunger and having a rectangular opening in its side wall. The housing has a knife-edged slightly concave indent on the bottom of the housing opposite the rectangular opening, which indent generally conforms to the arch section of the necked down portion of a beverage can. When the concave indent is placed on the lip of a can laying on its side and forced down the can will “snap” upright, through the rectangular opening and into the housing. The can is then retained in the housing around the necked down portion by a foam/rubber lining located at the lower inside end of the housing. Then the weighted plunger is forced down onto the can, crushing the can and expelling any fluids remaining inside the can through the drinking opening. The can may then be ejected from the device by pressing an ejector rod.
