Abstract
Abstract This disclosure relates to a collapsible carton having a leakproof corner wherein the web or gusset defining the corner is foreshortened whereby the necessary seal adjacent the base of the carton is provided and at the same time the flap may be securely secured in place in conventional manners. Furthermore, where desired, the carton may be constructed so that the walls may be folded into superimposed relation with respect to the base and wherein hinging of the carton is in the area of the flaps so that the necessary hinge lines do not undesirably detract from the appearance of the carton.
