A foldable, self-standing container is disclosed which can be formed of plastic, paper, metal, or other materials and can be sealed with an integral top. The container is formed with unique fold lines in two side sections and the bottom section. When folded, the self-standing container lies flat and can be instantly opened into the upright, self-standing position by exerting opposing forces on two exposed sides of the container. When formed of metal, the fold lines are made in the form of joints, preferably connected with a resilient, liquid-tight, heat-proof sealant material. Also disclosed is an efficient method for bulk dispensing of the containers as well as a method of making and folding the containers, including an inventive box folding device. A method for permanently forming a curvature in a plastic bead and groove type zipper-type closure device is also provided in order to continuously extend the zipper-type closure device around a plurality of the sides of the foldable, self-standing container.
