Claim 9

A reclosable bag assembly, comprising: a. an outer bag having front and back panels peripherally joined at three edges, such joining being provided at opposite longitudinal edges by a pair of gussets, the fourth edges jointly defining a mouth; b. a liner bag disposed within said outer bag and having front and back panels peripherally joined at three edges, such joining being provided at opposite longitudinal edges by a pair of gussets, the fourth edges jointly defining a second mouth coinciding with the first-named mouth; and c. a strip of flexible metal foil disposed between and engaging only said front panels of said bags, a portion of said strip having been folded over upon itself between said bags to provide a configuration which augments the resistance to bending of the foil, the elongated edges of said strip extending parallel to the fourth edges of said front panels, said strip being fully enclosed by said panels and secured in a fixed position, the ends of said strip extending for nearly the full width of said front panels to be in juxtaposition with said gussets when the gussets are inwardly folded.
