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 packageand 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 a part of the package or a separate component 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.

[ We claim:] [1.]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 upper edge and an upper end portion contiguous therewith which 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 secured on said first panel adjacent said mouth, said second closure element being secured on said second panel adjacent said mouth, said first closure element being an elongated, substantially rigid member extending substantially the width of said first panel and having a tongue extending substantially the width thereof, one portion of said first panel being fixedly secured at and along said tongue of said first closure element, said second closure element being an elongated, substantially rigid member extending substantially the width of said second panel and having an undercut groove extending substantially the width thereof, said tongue of said first closure 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 second closure element including a lower edge, a lower portion contiguous with said lower edge, an upper edge, and an upper portion contiguous with said upper edge, one portion of said second panel being fixedly secured to said second closure element along one of said upper or lower portions, and another portion of said second panel being movable relative to said other of said upper or lower portions of said second closure element to enable said other portion of said second panel to be interposed between said tongue and said groove when said snap closure has sealed said mouth.
