Abstract
A heat-sealable leakproof container formed from a cut and scored blank of paperboard incorporates foldable gusset panel structural configuration which obviates leakage from the container and enhances its strength and rigidity. The container includes a pair of side wall panels adapted to be secured in an overlapping relationship which are foldably attached at front and rear edges of a bottom wall panel. A pair of double gusset sections are foldably secured at opposite sides of the bottom wall panel and also to the side wall panels. Each gusset section comprises a first triangular panel foldably secured to the bottom wall panel with second and third triangular panels foldably secured between the first triangular panel and the respective side wall panels. The second and third triangular panels are adapted to overlap and the fold line in between nest together when the gusset section is folded to provide a strong leakproof joint.
