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. The cover is extended over the upper edge of the double-wall surface portion with the gripping opening to provide a stiffening web.
