Containers with reclosable opening means

A reclosable container comprising in combination a generally rectangular shaped knockdwon body portion forming a cavity to retain a commodity therein, said body portion having a plurality of rectangularly located body-forming walls, and said body-forming walls each respectfully having first and second end margins thereon, said body portion having an aperture communicating with said cavity to permit loading of a commodity therein, closure means including a closure-forming panel operatively hingedly connected to the first end margin on the first of said body-forming walls and capable of being shifted to a closurewise position over said aperture, said closure-forming panel having a first pair and a second pair of end margins thereon and being substantially parallel to said body-forming walls and being coextensive with at least one of said body-forming walls when the closure means is in an open position and substantially perpendicular to said body-forming walls when the closure means is in the closure-wise position, a flap extending from at least three of the end margins on said closure-forming panel and each being capable of being struck in directions where they lie substantially in perpendicular relation to the exterior surface of said closure-forming panel, a strengthening and retaining frame which has a shape substantially conforming to the shape of said closure means at least partially surrounding said closure-forming panel, said strengthening and retaining frame having a side wall formed of a reinforcing material, and first and second flanges extending inwardly substantially perpendicularly from said side wall and being spaced apart from each other by a distance approximately equal to the length of each of said, flaps, said side wall of said strengthening and retaining frame being substantially parallel to all of said body-forming walls when said closure means is in the closurewise position, at least three end margins of said closure-forming panel being operatively retained by the first flange on said side wall and the outer end of said flaps snugly engaging the second flange on said side wall when said strengthening and retaining frame is assembled with said closure means, said flaps being located substantially in parallel relationship to at least certain of said body-forming walls when the closure means is shifted to the closurewise position, said second flange having a bearing surface which faces said first flange and retentively engaging the outer end of said flaps, said bearing surface having a width substantially greater than the thickness of the said outer end of said flaps, said last named three end margins on said closure panel engaging said side wall and being retained by said side wall and said first flange when said strengthening and retaining frame is assembled with said closure means, whereby said closure means and said strengthening and retaining frame may be opened and closed with respect to the aperture in said body portion through the hinged operative connection of said closure-forming panel to one of said body-forming walls at a fourth margin on said closure-forming panel.
