Abstract

A bag closure device includes a pair of annular closure members which are movable into and out of a nested relationship with one another and are preferably connected to one another by an integral hinge. In the preferred embodiment, one of the closure members is L-shaped in configuration and defines a concave seating surface while the other closure member is U-shaped in configuration and defines a convex engagement surface. The convex engagement surface is thus positioned annularly adjacent to the seating surface when the two closure members are nested so as to frictionally capture, and thus close, a portion of a flexible bag therebetween. An annular lip may be formed on the L-shaped closure member so as to provide frictional resistance against separation of the closure members when they are nested. Further removable locking capability may be provided by a cooperating aperture (defined in a foldable tab associated with one of the closure members) and an upright stake (associated with the other closure member) having an enlarged head press-fitted through the aperture. Tamper evidence may also be provided by a melted terminal segment of the stake.
