ABSTRACT:
A device for washing a can comprising a support for supporting the can on one of its lateral sides for sliding movement from a prepunch position to a punch position. A knife is positioned adjacent the support and has a cutting edge presented toward the bottom of the can so that the knife will destructively pierce the bottom of the can whenever the can is manually forced against the knife. The knife is shaped to provide a channel for liquid contents of the can to drain therefrom whenever the can is pierced by the knife. A spray nozzle is mounted with respect to the knife so as to protrude within the interior of the can whenever the knife pierces the can. A timing device causes the spray to spray the interior of the can throughout a 30-second cycle.
