A snap closure for a flexible, gusseted package and a flexible gusseted packing including the closure. The package includes a mouth portion arranged to be opened to provide access to the contents of the package. The package is formed of a flexible material and includes a front panel, a rear panel, and a pair of opposed side gussets. The panels and gussets each include a top portion, which between them define the package's mouth. The package's mouth is initially sealed but arranged to be opened, e.g., peeled apart. The snap closure enables the resealing of the mouth of the package and is made up of a pair of elongated elements, one of which includes a tongue extending along the length of it. The other element includes an undercut groove extending along the length of it. The elements are arranged to be pressed together, whereupon the tongue of the one element enters the groove of the other element with portions of the panels and side gussets tightly interposed therebetween. The closure elements may be longitudinally rigid or may be segmented to flex in the longitudinal direction to facilitate opening. Moreover, the closure elements may be a part of the package or separate components for use therewith. In any case when the closure is utilized it recloses the mouth of the package to preclude or minimize the ingress of air into the package.

[ I claim:] [1.] In combination a package having an interior for holding material therein and a snap-closure therefor, said package being formed of a flexible material and comprising first and second panels connected to each other, each of said panels having an outside surface, an inside surface and an upper end portion whose inside surfaces conjoin to form a mouth for said package, said mouth being openable to provide access to the interior of the package, said snap closure being arranged for reclosing and sealing said mouth and comprising a first closure element and second closure element, said first closure element being located on said outside surface of said first panel adjacent said mouth, said second closure element being located on said outside surface of said second panel adjacent said mouth, said first element being an elongated, segmented member having a longitudinal axis extending substantially the width of said first panel and a having a tongue extending substantially the width thereof, said second element being an elongated, segmented member having a longitudinal axis extending substantially the width of said second panel and parallel to said longitudinal axis of said first element, said second element having an undercut groove extending substantially the width thereof, said tongue of said first closure element being arranged to be snap-fit into said undercut groove of said second closure element with portions of said panels tightly interposed therebetween to close the mouth of package to prevent the ingress of air into the package through said mouth, said first closure element having a plurality of narrow slits spaced apart from one another extending outward transversely to said longitudinal axis of said first closure element, said second closure element having a plurality of narrow slits spaced apart from one another extending outward transversely to said longitudinal axis of said second closure element, said slits in said closure elements being arranged to enable said closure elements to be bowed outward with respect to each other to facilitate the opening of said mouth of said package after said mouth has been closed by said closure.
