A circumferential closure for a bag which permits hinged opening of the bag at substantially all position on the circumference and selected full or partial closure. The closure comprises a single zipper (or similar closure mechanism) track wherein one end overlaps the track of the other end by being inserted therewithin. The zipper mechanism comprises four pull elements in two sets, arranged such that juxtaposition (or separated) sequence of the two sets of pairs provides for full closure of the zipper and wherein disposal of a set of pairs between another set of pairs provides for full opening of the zipper, wherein the closure is hinged at the site of the zippers.

[ What is claimed is:] [1.] A receptacle comprised of a separated closure member and a receptacle member, each having matched corresponding circumferential edges; wherein the closure member comprises means for providing selected full and partial circumferential engagement between the closure member

[ What is claimed is:] [1.] A receptacle comprised of a separated closure member and a receptacle member, each having matched corresponding circumferential edges; wherein the closure member comprises means for providing selected full and partial circumferential engagement between the closure member and receptacle member; said means for providing selected engagement being comprised of a zipper track having two separate interlockable track elements, with said two interlockable track elements being separately disposed at the matched edges of the closure member and receptacle member; wherein the interlockable track element, at the edge of the closure member, is elongated with two ends and wherein one end overlaps the other end; and wherein the interlockable track element, at the edge of the receptacle member, is correspondingly elongated with two ends, wherein one end correspondingly overlaps the other end; said means for providing selected engagement further comprising four zipper pull members which interconnect the two separate interlockable track elements, each of the zipper pull members being movably pullable on said zipper track, with movement in one direction effecting an interlocking of the interlockable track elements and movement in an opposite direction effecting opening of the interlocked track element; wherein one of said zipper pull members is positionable between the corresponding ends of the interlockable track elements and another of said zipper pull members being positionable between the remaining corresponding ends of the interlockable track elements, said two end-positionable zipper pull members comprising a first set and the remaining two zipper pull members comprising a second set; wherein close juxtaposition of all of the zipper pull members in a sequence wherein one set is interposed between the other set, at substantially any positions on said zipper track, effects opening and separation of the closure member and the receptacle, with said zipper pull members comprising a hinge for said opening.
