Abstract
A flexible, sealable container apparatus having a substantially pinch-bottomed configuration prior to expansion of the bag during cooking. The container apparatus includes substantially quadrilateral regions of adhesive. The shape and positioning of the quadrilateral regions, with diagonals substantially collinear to panel edges of the container apparatus, serves to articulate the container apparatus into a substantially rectangular-bottomed configuration during cooking, while improving the integrity of the bottom region seals against blowout and/or leakage.
