ABSTRACT:
A packaging case formed of a boxboard and having annular perforations provided on a wall to enable an opening to be formed when a portion surrounded by the perforations is removed by cutting the perforations.
On the wall of the case on which the perforations are provided there is embossed a ruled line extending along the perforations in overlapping relation therewith, by which the strength of the portion of the boxboard in which the perforations are present is lowered so that as the perforations are cut in order to form the opening in the case, the force of tearing is guided by the ruled line along the perforations. By this arrangement the portion surrounded by the perforations can be accurately removed by a relatively small force of tearing and an opening defined by the perforations can be thus accurately formed without the path of the tearing action being allowed to deviate from the perforations.
