ABSTRACT:
Beverage containers are commonly made with a ring at the top of the can for pulling a knock-out from the can top to provide a discharge opening through which a person can conveniently drink the contents of the can, or pour them into a glass or cup. The can top gathers dust and other contaminants that are a health hazard. This invention locates the discharge outlet at the bottom of the can and in a recessed compartment, and prevents contamination by closing off access to the can bottom by a shelf or other surface on which the can rests, so that the can itself acts as a shield to protect the discharge outlet area from contaminants.
