Abstract
A packaging for filling materials which are capable of flow comprises side walls (1) of coated cardboard or the like, which are joined together in a tubular configuration by way of at least one longitudinal sealing seam (4), and end walls which are disposed at the ends of the tube member (1), wherein one end wall which forms the cover (2) of the packaging comprises thermoplastic material without a carrier material, is injected to the side walls (1) along its outer edge (6) and has a pouring spout (13) which can be folded inwardly of the outside contour of the packaging for example for transportation, while the other end wall which forms the bottom is quadrangular and has a transverse sealing seam with triangular flaps which are folded over onto an adjacent wall portion. In order to improve such a packaging, with the aim of providing a properly sealed package, while being easy to open, and also providing the possibility of improved and versatile usability, in particular as an aseptic drinking bottle for infants, the invention provides that the cover has a cover wall portion (20) which converges in a tapered configuration towards the center and which leaves a central opening, with a spout or mouthpiece rim portion (14) having a closure member (13) fastened thereto, wherein the cover wall portion (20) is preferably of a frustoconical configuration and the spout rim portion (14) is of a frustoconical or cylindrical configuration.
