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.
Claims13
A device for washing a can having lateral sides, a top, and a bottom, said device comprising;
- a support having a first end and a second end for supporting said can on one of said lateral sides for sliding movement from a pre-punch position to a punch position;
- a knife positioned adjacent said support and having a cutting edge presented towards said bottom of said can when said can is in said pre-punch position whereby said knife will destructively pierce said bottom of said can whenever said can is manually forced against said knife for movement to said punch position;
- said knife being shaped to provide a channel for liquid contents to drain from said can whenever said can is pierced by said knife,
- a spray nozzle positioned within the channel of the knife so as to protrude within the interior of said can;
- means connecting said spray nozzle to a source of fluid under pressure whereby said spray nozzle will spray said fluid into the interior of said can, and
- said support being inclined, said first end thereof being lower than said second end, said knife being positioned adjacent said first end of said support whereby the fluid contents of said can will flow towards said knife and outwardly through the hole in said can caused by said knife.
