ABSTRACT:
A canister blank has four injection molded side walls having bottom wall sections extending therefrom, which are arranged to be bent at right angles to the side walls to form the container bottom. The side walls have plastic ledges with triangular cross sections projecting at the transition region from the side walls to the bottom wall sections. One concave side of the triangle forms a continuation of the external surface when the bottom wall section is bent and the other concave side of the triangle forms a part of the container bottom when the bottom wall section is bent. The point of the triangle forms an outside edge at the bottom.
