Abstract: The container frame (1) is constructed with three layers, the middle layer (3) having a smaller width than the inner and outer layers (2, 4). Insertion slots (5, 6) are thereby formed at the top and bottom of the container frame. A pallet (7) made of carton forming the bottom of the container comprises a base plate (8) and feet (9) made of layers of cardboard, glued to its underside. On the side of the base plate (8) lying opposite the feet (9) is glued a cardboard bottom element (10), whose edges (11) are bent upwards. The insertion slot (6) of the container frame is placed on the bent edge (11). A lid element (12) with bent over edges (13) can be placed in the upper insertion slot (5). All components of the container consist of cardboard or corrugated cardboard and glue and are suitable for recycling.

Abstract: Three paperboard webs are glued to one another with as little expenditure of energy as possible. After leaving the gluing apparatus, the finished sheets cut to size are ready for shipment. The middle paperboard web is passed through between two steel rolls which apply glue homogeneously to both sides of the web. High linear pressure is produced in the region of the generatrices of the steel rolls respectively touching the web. Such pressure is necessary in order that a highly viscous polymeric synthetic or natural adhesive, preferably with a solids content of more than 50%, can be used. No special drying facilities are needed, and the water-soluble glue allows recycling without problems.
