FIELD: package and storage.

SUBSTANCE: invention relates to container (1) comprising bottom panel (2), front panel (3), two side panels (4), rear panel (5), and top panel (6). Front panel (3) and two side panels (4) each comprises perforation line (7) so that hingedly connected lid (8) is obtained when perforation lines (7) are broken. In front panel (3) there is a straight or curved row of perforations (23) which forms edge (24) of lid (8) after the perforations have been broken. Each perforation line (7) in side panels (4) is a row of perforations (23) comprising a pair of first and second cuts (26, 27) which form a blunt angle (α). These perforations (23) form a row of tooth-shaped regions (25), each delimited by first cut (26) and second cut (27), respectively, from two adjacent but non-contacting perforations (23). First cuts (26) are arranged parallel to each other but staggered so that they are not arranged along one line, wherein at a distance from each end of folding line (21), but close thereto, end cut (32) is made over the entire thickness of rear panel (5), wherein each of end cuts (32) consists of two straight joining segments that are not perpendicular to folding line (21).

EFFECT: flip-top container with tooth-shaped side perforations is disclosed.
