Abstract
A two-piece shock absorbing closure defined by a ring and a plug, the plug including a centrally generally circular unreinforced concavely axially outwardly opening end panel, an annular axially projecting plug portion bounding the end panel, the ring including an axially opening annular channel for receiving the plug portion, the annular channel being defined by inner and outer channel walls and a bight wall therebetween, a wall radially outboard of the outer channel wall responsive to insertion of the plug portion into the annular channel for radially inwardly deflecting the outer channel wall to bring the same into intimate friction engagement with the plug portion, and another wall between the end panel and the plug portion for effecting the deflection of the end panel from its concave configuration to a convex configuration in response to shock forces imparted to the closure and/or an associated container thereby absorbing said shock forces to prevent plug popping.
