  • Patent number: 4228898
    Abstract: A reclosable carton and blank therefor are provided wherein the interior of the carton is formed into a pair of upright continguous compartments. The carton includes a pair of wall panels and a pair of narrow side panels. The upper sections of the panels converge towards one another to effect top closing of the carton. A top closure flap is foldably connected to one of the wall panels and retains the upper sections of the wall panels in convergent relation. The upper section of each side panel includes a center segment having tapered side edges and gusset segments foldably connected to the tapered side edges and to the adjacent peripheral portions of the wall panel upper sections. When the top of the carbon is initially closed, the gusset segments of each side panel are disposed in face-to-face contacting relation and are sandwiched between corresponding portions of the wall panels.
