Container having stabilized base and its manufacture

摘要

A container and a process for its preparation, the container (20) having a base (26) and walls (28) extending upwards therefrom. The container is formed out of a single film of material in which at least an inner face is made of a heat weldable material and two side edges of the film sheet are welded to one another and overlapping portions of a bottom edge of the film sheet are welded to over another. The container comprises rigid skirt (24) portion extending at right angle below the base and is formed in a regular geometric shape. The container's base assumes a shape corresponding to the shape of the skirt portion and the shape of the skirt portion is fixed by welding overlapping portions of the wall to one another.
