ABSTRACT:
The present invention briefly relates to a package box (11) for the liquid tight sealing of the contents, preferably a liquid, which box (11) is folded from a cardboard blank, the side of which facing inwardly in the package box (11) is coated with a thin layer of plastic. The closing flaps (12a, 13, 14, 15) extend each from its corresponding wall of the box (11) and are delimited from respective wall by a folding line (17). The longitudinal corner (19) of the box (11) between box bottom and lid is defined by two parallel folding lines (24, 25) and the recesses separating the flaps (12a, 13, 14, 15) terminate at a distance from the folding lines (17) of the flaps (12a, 13, 14, 15). The recesses preferably terminate in a section, the flange (23) of which is parallel to the folding lines (17) of the flaps (12a, 13, 14, 15) the length of such flange portion corresponding essentially to the distance between two parallel corner lines (24, 25).
