<p>The blank (10) has longitudinal walls (16, 20), transverse walls (22, 24), a rear wall (18) and a front wall (14) including detachable regions (70-86) surrounded by a circular separated perforation. The regions are separated from the front wall at the perforation. The blank is made of cardboard or paperboard. Sections (12, 30) form a container. One of the sections (30) is arranged before a subregion of the front wall, where the subregion is connected with regions. Connection force between one of the sections and the regions is larger than force required for separation of the perforation.</p> |
