Corrugated cardboard box

摘要

The box is made from at least double-layered corrugated cardboard with the outer layer (4) having a tear strip (6). The inner layer (5) has a horizontal cut (11) at a distance above the tear strip. The outer and inner layers adjoin one another without adhesive in the area (13) between the tear strip and horizontal cut. The unstuck area between the two layers can be formed by a strip which remains unglued during manufacturing of the corrugated paper. The unstuck area could be formed by a paper strip applied to the glued area (5) during manufacture.
