SEALED BAG FOR LIQUID WITH WELDED NOZZLE FOR DRINKING OR DISPENSING Russian patent published in 2011 - IPC B65D33/38 

FIELD: packing industry.

SUBSTANCE: sealed bag for liquid with a welded tightly closed nozzle for drinking or dispensing form two closed chambers, which are either separated from each other by means of a separating strip in one solid bag, or are developed either by welding of two separate bags along the separating strip, or by development of a chamber by application and placement in hot condition around the nozzle for drinking or dispensing, which is welded into the other chamber, and which is thus welded to the specified chamber. In the separating strip with the help of welding there is a nozzle installed as tight in closed position for drinking or dispensing so that in the open position it connects two chambers, and that the nozzle protrudes either into the first chamber or into the second chamber, besides, one chamber of the bag is designed to hold liquid, while the other chamber of the bag as an opening protective chamber tightly closes the outlet side of the nozzle for drinking or dispensing, and besides, the specified chamber, acting as the protective chamber may be opened manually without formation of any wastes to be removed further. The nozzle for drinking or dispensing is a solid cast nozzle with a base and a wedge-shaped nozzle made of material having rubber elasticity, besides, the surface of the upper edge of the nozzle is tightly closed with thin film, which is broken only as a result of mechanical action of hands or mouth and without formation of any wastes to be removed, and namely as the nozzle rotates or when nozzle edges are pressed in direction of the slot or when a drinking straw is inserted.

EFFECT: invention makes it possible to increase convenience of use.
