Abstract
Abstract An easy open reclosable end unit which includes a metal end unit securable to a container body by means of a seam and having a dispensing opening therein. The dispensing opening is closed by a removable closure initially bonded to the end unit and being peelable therefrom. A cam mechanism is provided for effecting the initial rupture and peeling of the closure with the cam unit being lockable with respect to the closure after the end unit has been seamed to the container. The raw edge of the metal defining the dispensing opening is provided with a guard member and the closure has a plug portion tightly fitting within the guard member and interlocking therebelow to effect reclosing.
