In order to provide such a packaging means with a particularly advantagoeus bottom, the invention proposes that at least two mutually oppositely disposed triangular flaps of the bottom are folded inwardly into the plane of the bottom or outwardly on to the side wall, about the lower edge between the bottom and the side wall, and fixed in that position.

Abstract: Described are opening means on a package for liquid. The pouring spout (3) can be formed by being torn open along a perforated line (8a, 8b) which begins at a starting point (14) below the front tip (17) and which terminates approximately in the middle of the upper end wall (6, 6'). In order to provide an air space of sufficient size above the liquid in the package, and an air entry space at the rearward end of the cut, so that the pouring jet of liquid can be accurately guided in passing over the front tip of the pouring spout, the invention provides that the perforated line (8a, 8b), in the lower triangular portion (13, 13') of the triangular flap, has a bend point (10) from which its path towards the outer, lower starting point (14) is directed markedly more sharply towards the bottom, and that a continuous cut line is provided in the starting point (14).

Abstract: A pack for containing materials which are capable of flow includes a tube formed by a longitudinal sealing seam, along with a bottom and a cover closing the tube ends. The cover is formed from thermoplastic material without a carrier material, is injected on the tube, and has a pouring spout. The tube comprises cardboard which is coated with thermoplastic material on one side. The bottom is quadrangular, formed from the folded-over tube of the pack of a fold-type closure. The cover and the cross-section of the pack, at least in the region of the cover, are round. To improve such a pack with a handle so that the final consumer enjoys improved handleability and transportability, the invention provides that a portion of the tube wall, which adjoins the periphery of the cover, is folded onto itself, forming a handle, and is joined to provide a double-wall surface portion in which a gripping opening is provided.

Abstract: Pieces of tube are produced from a flat flexible web by feeding the web intermittently into apparatus which first makes transverse incisions from each edge partly across the web at a spacing equal to the desired tube lengths. The side portions between the incisions are then folded along longitudinal fold lines so that their end edges overlap and are welded together. In a subsequent operation, the non-incised central flat portion of the web is severed in line with the incisions and the tube elements thus formed are then moved transversely to the direction of web movement by a reciprocating slide to stand upright on tube-shaping members.

Abstract: Apparatus for shaping liquid containing packages is disclosed. The apparatus comprises a take-off conveyor which includes a multitude of support parts which form a conveyor belt. The support parts are movable with respect to each other and point transversely outwardly from the conveyor path. A plunger moves out from the surface of the support part towards a side wall of the package to indent the same at a certain portion of the package formation cycle. A switch cam plate or the like causes movement of the plunger between a contact position in which the plunger contacts and indents a portion of the package and another position in which the plunger does not engage the package.This application is a continuation, of application Ser. No. 198,161, filed Oct. 17, 1980, now abandoned.

The laminate is provided with at least one auxiliary crease line where the crease lines converge or intersect in order to prevent crack formation in the layers of the laminate and consequent leakage in the container formed therefrom. A method is also disclosed for manufacturing a laminate in which the laminate is provided with auxiliary crease lines after the converging or intersecting crease lines have been provided.

Abstract: Packing machines for the manufacture of packing containers frequently produce these from web-like material, which is supplied to the machine in the form of a roll. During the production the material web is advanced through the machine along a path defined by guiding rollers, guiding rails and similar elements. These guiding elements obstruct in an undesirable manner the movement of the material web through the machine. This difficulty is eliminated in accordance with the invention in that a front and a back part of the material web are advanced alternately. In accordance with the invention, moreover, an arrangement is proposed with first and second web-advancing elements, which operate with alternating working strokes.
