Abstract

This specification discloses improvements in push-in easy opening closures of the pressure releasing type which are designed to substantially reseal once a digitally applied push-in force causing them to open is released. In one form of the invention, the pressure releasing closure is formed partly within the confines of a pouring closure and partly outside the pouring closure whereby the pressure releasing closure is permanently opened when the pouring closure is opened. In another embodiment, the pressure releasing closure is connected to the can end adjacent its countersink whereby the opened closure defines a liquid draining hole when opened. The specification also discloses a can end having a closure formed so that the sheet metal at its hinge is relatively undisturbed. A method of forming such a closure is also disclosed.
