ABSTRACT:
The problem of providing tight-fitting closures for containers is solved by the closures and the methods of installing and removing closures utilizing a closure (20) which includes a central portion (21) and an annulus portion (22) hingedly connected to the central portion by a hinge (23) to enable at least a portion of the annulus portion to contract during insertion and removal operations. The annulus portion pivots to an expanded position to become compressed between the central portion and the orifice surface (25). A retaining portion (68) in a modified form of closure serves to hold the outer edge of the annulus portion relative to movement of the central portion and to prevent premature removal. In installing and removing, the closure is readily adapted to be turned at an angle to the axis of the orifice for easier insertion and removal and for bung-type closures the filler apparatus for a beer barrel is useful in installing these closures.
