ABSTRACT:
A container formed from a single cut of material, with a bottom of the container having a rectangular or square surface area and being bordered by prepared folding lines around which strips are folded open that connect to the bottom and form shell surfaces of the container. In each case two additional prepared folding lines are provided between the strips that extend at right angles to each other with the additional folding lines extending toward each other and enclosing an angle of less than 90.degree. and deviating from the direction of the folding lines that border the bottom portion of the container so that areas of the strips that are located outside of the extension of the folding lines of the bottom portion are folded over and may be placed against the outside of the strip that was folded over. The shell surfaces are enclosed by a circular flanged roll which is formed by the edges of the folded open strip. Corners of the cut of material are recessed or notched in such a way that the edges intended for the flange roll at junction points only overlap along a short length in a circumferential direction of the flanged roll. A height and configuration or shape of the recesses or notches in the corners is selected so that a transistion of the flanged roll at the junction points of the edges to the shell surfaces has not cutting edges, and the flanged roll is formed of three layers.
