Embodiment Construction

[0012] As shown in FIG. 1 , the fluid bag 1 includes two chambers 6 , 7 separated from each other. The bag 1 is formed by welding two plastic films 4 , 5 stacked on top of each other along their edges 3 . At the same time, the drinking tube or dispensing tube 2 is sealed and welded at the dividing strip 8 which divides the bag into two chambers 6 , 7 . The edge portion 11 of the bottom of the pocket 6 is initially not connected. The lower bag chamber 6 here is a liquid chamber. It is then filled with liquid from below, for which the bag needs to be turned 180° so that it is turned upside down. In this position the bag is filled and the edge parts 11 are subsequently joined together on its underside. The drinking or dispensing tube 2 itself is made as a one-piece plastic injection-molded part. The tube 2 comprises a base 10 and a pouring nozzle 9 associated therewith. The upper bag chamber 7 completely surrounds the welded pouring nozzle 9 and seals it against the outside....

Abstract

The liquid-containing bag is produced integrally from two sheets (4; 5) which are welded to one another along the edge region (3), and the bag forms two chambers (6; 7) which are separated from one another by a separating strip (8). A drinking or dispensing spout (2) is welded with sealing action in the separating strip (8), in which case this connects the two chambers (6, 7) in the open state, the one bag chamber (6) being intended for receiving the liquid, while the other bag chamber (7), as a protective chamber, encompasses the outer spout end (9) and encloses the same with sealing action.

Description

technical field [0001] The present invention relates to a sealed liquid bag with an integrally welded drinking or dispensing tube. Background technique [0002] Fluid bags of various types of closures are known in various forms. The bag can be made of hide or gut, rubber material or plastic film material. Flexitanks made of plastic film material are especially useful because they are lightweight, can be made in different shapes, making them easier to transport and store, and because empty bags don’t take up much space, and finally because the Fluid bag for easy handling. Since such plastic film flexitanks are mostly considered disposable consumables, the closures associated with them must be able to be produced very inexpensively. In the field of medicine, such bags can also be used to prepare injections. Such bags must also have the original packaging seal. However, currently known solutions are very expensive. These closures consist of several parts and are therefore...
