Abstract: A multipurpose bag is formed of two plastic foil layers joined together to define a top, a bottom, and opposing sides. Peripheral joints between the layers extend along the bottom and the sides to define an inner chamber, the joint along one of the sides being divided by an unjoined area into top and bottom parts.
