Abstract
Abstract Described is a container for liquids with a tube (1) formed by a longitudinal sealing weld (4), at the ends of which bottom and lid (8) are arranged. The lid (8) consists of thermoplastic material without supporting material and is attached by injection moulding to the tube 1 along its upper edge. Furthermore, the lid (8) is provided with a pouring device (22), whereby the tube 1 consists of cardboard covered on both sides with thermoplastic material, the bottom is quadrangular and is formed as folded closure from the folded tube (1) of the container. To facilitate easier opening and that preferably the closing cap can be kept open, but can also be closed again, the invention envisages that the tube (1) has a quadrangular cross-section along its total height, that the paper fibres of the cardboard are arranged crosswise to the longitudinal sealing weld (4), that the latter is arranged close to an edge (5) of the tube (1), that the lid (8) is quandrangular when viewed from above and the pouring device (22) with molded-on handle 14 is arranged within the quadrangular outer contour of the container.
