Abstract of the Disclosure Stand-Up Bag A bag for containing preferably liquid products is made of a heat-weldable sheet material, suitably a compound sheet material, and has a rear face, a front face (2) and an insert bottom (3). Disposed at an upper portion of the front or rear face is a threaded closure (6) comprising a screw-threaded pipe socket (7) and a screw cap (13). The pipe socket penetrates the respective face of the bag and is bonded to the interior surface thereof with the aid of a welding flange (8) of larger diameter (D). the welding flange has a chamfered outer rim (14) cooper- ating with the sheet material (1) to form a V-shaped circumferential groove (15) which is at least partially filled with the molten plastic material of the sheet during the welding operation. The threaded closure permits the bag to be repeatedly opened and closed for piecemeal dispensing its contents.
