<p>The container has a four-side, or polygonal base and a sealing lid. Its body (11) consists of a flat sheet, and the corner wedges (15) between the side walls (14) are folded along lines (17) bisecting the angles at their apexes, so as to protrude into the interior. While the sheet is flat, embossed grooves can be formed along these lines. The wedges can be divided by cuts between the side walls, the cut edges being then overlapped and glued together. Lugs for the lid can be provided along the tops of the side walls.</p> |
