Abstract
An opener structure for a container includes a slidable plate juxtaposed against an external wall of the container. Retainer devices such as rivets retain the plate against the wall but permit relative sliding between the wall and the plate. A resilient punch supported from the plate rests on a shelf defined by the wall. A region of weakness lies adjacent the shelf so that if the plate slides away from the shelf, the punch will pierce the line of weakness and rupture it. A lever is provided to cause the plate to slide away from the shelf.
