The invention describes a liquids package includes a tube formed by a longitudinal sealing seam and a bottom. A cover, which consists of thermoplastics synthetic material with no carrier mateial, is molded onto the tube and comprises a pourer device. The tube consists of coated cardboard. The bottom is tetragonal and is constructed from the folded-over tube as a folded-over closure. A handle connected to the cover is mounted laterally on the tube and below the cover. To allow the end user ease of handling and so that the package can be space-savingly stored and transported, while ensuring that the package can be produced from a flat strip of cardboard, while forming a quadrilateral outer contour of the package, the outside dimensions of the bottom are equal to the tetragonal cross-sectional dimensions of the package from the bottom to the cover. The handle together with the cover is injection molded on within the quadrilateral outer contours of the package.

Liquids package with handle

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.
