PCT No. PCT/EP91/01563 Sec. 371 Date Apr. 22, 1992 Sec. 102(e) Date Apr. 22, 1992 PCT Filed Aug. 16, 1991 PCT Pub. No. WO92/03352 PCT Pub. Date Mar. 5, 1992.There is provided a cardboard packaging for liquids which consists of a folding box, an inner bag arranged therein and made from a plastic material, and of a withdrawal nozzle which is accessible from the outside through a hole formed in one wall of the folding box. The withdrawal nozzle comprises a base plate which is welded or bonded in liquid-tight fashion to the bag at the inner side of said bag in a weldless area thereof. The inner bag is only bonded to and easily detachable from the folding box wall that includes the hole for the withdrawal nozzle, but, apart from this, is not bonded to the walls of the folding box. The withdrawal nozzle is therefore secured against rotation, and the bag is sufficiently fixed in the folding carton. In addition, it can easily collapse during emptying, and the packaging can be easily disassembled into its cardboard and plastic parts after use (FIG. 2 ).
