ABSTRACT:
A bag for containing liquid products, for example, is made of a heat-weldable sheet material. The sheet material may suitably be a compound sheet material which provides a rear face, a front face and an insert bottom. Disposed at an upper portion of the front or rear face is a threaded closure comprising a screw-threaded pipe socket and a screw cap. The pipe socket penetrates one face of the bag and is bonded to the interior surface of the bag with the aid of a welding flange having a larger diameter. The welding flange has a chamfered outer rim cooperating with the sheet material to form a V-shaped circumferential groove 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.
