ABSTRACT:
A plastic film liquid pouch is formed from impermeable film sheet material and has opposed side walls with sealed circumferencial edges to form an enclosed chamber. A liquid product is provided in the chamber and a space is also provided to permit expansion of the liquid. An internal straw restraining passage is formed by seals between the opposed side walls. The straw restraining passage communicates with the liquid chamber and a straw is held loosely captive inside the passage and axially displaceable therein. The straw restraining passage defines a reduced cross-sectional area of the chamber whereby the opposed side walls of the bag at the restraining passage may be collapsed towards one another by the fingers of a user person thereby displacing a restricted quantity of liquid to expose the straw to grasp the straw and push an end of the straw through the film sheet material whereby to extract the liquid from the pouch either by sipping it through the straw or by compressing the pouch to force the liquid through the straw.
