A local connection of contact surfaces of top and bottom sheets is formed in a defined connection zone. The zone is polygonal and the top and bottom sheets jointly form within the periphery of this zone a connecting lip with their first side faces located opposite one another cut obliquely through their sheet thickness. These first side faces of the sheets and their adjacent obliquely-oriented second side faces in the zone are complementarily beveled in the form of a conical wall running downwards and inwards, so that in the vicinity of these second neighboring side faces the underside of the bottom sheet protrudes inwards past the top surface of the connecting lip at the location of the top outside edges of its first side faces. A method and an apparatus are arranged to implement the local connection.

The invention relates to a container precursor comprising a wall, wherein the wall a) surrounds an interior region, and b) comprises a first wall region and a second wall region; wherein the first wall region comprises a first layer sequence comprising a first wall layer, a second wall layer and a third wall layer as overlying layers from the interior region outwards; wherein, in the first wall region, a second carrier layer is characterised by a smaller layer thickness than a first carrier layer, or a third carrier layer, or both; wherein the second wall region comprises a second layer sequence comprising first wall layer, a second wall layer and a third wall layer as overlying layers from the interior region outwards; wherein, in the second wall region, the second wall layer is connected to the third wall layer; wherein, in the second wall region, the third carrier layer is characterised by a larger layer thickness than the first carrier layer, or the third carrier layer, or both. Further, the invention relates to a process for manufacturing a container precursor, a container precursor obtainable through this process, a closed container, a process for manufacturing a closed container, a closed container obtainable through this process, a use of the aforementioned container precursor, and a further use of the aforementioned container precursor.

A blank is configured to be erected into a container including an inner tray and an outer carton frangibly connected to the inner tray. The inner tray includes an inner side wall and a bottom. The outer carton includes a top, an outer side wall, and a utility panel frangibly connected to the inner side wall.

A method and a sealing device for sealing a joint (5; 31) between two end sides (3, 13) of two contiguous panels (1, 11). The method comprises the steps of: holding (S1) an end side (3) of a first panel (1) close to an end side (13) of a second panel (11), whereby the joint (5; 31) to be sealed is defined by the adjacent end sides (3, 13) of the two panels (1, 11); sealing (S3) the joint (5; 31) with a first and a second adhesive tape (15, 17) by providing a first tape (15) to a first face (19) of the two panels (1, 11), said first tape (15) sealing the joint (5; 31) and being provided in the direction of the joint and providing a second tape (17) to a second face (21) of the two panels (1, 11), wherein the second face (21) of the two panels (1, 11) is the opposite face to the first face (19) of the panels, said second tape (17) sealing the joint (5; 31) and being provided in the direction of the joint.

The invention relates to a layout for a box, having a bottom wall, four sidewalls and a cover, wherein the sidewalls each share a crease line with the bottom wall; wherein adjacent sidewalls share a connecting surface, which connecting surface shares a crease line with each of the two adjacent sidewalls; wherein the connecting surfaces are provided with at least one diagonal crease line; wherein the at least one diagonal crease line of the connecting surface coincides in one point with both crease lines between each of the adjacent sides and the bottom wall.
