ABSTRACT:
A flexible stand-up liquid pouch is formed from a sheet of foil film laminate material whereby opposed side walls of the material are folded together with sealed circumferential edges to form an enclosed chamber. A liquid is provided in the chamber, and the side walls of the sheet material which form the container have raised portions which, when sealed together, cooperatively form an internal straw restraining passage inside the container. The straw restraining passage communicates with the liquid chamber and a straw is held loosely captive inside the straw restraining passage and is axially displaceable therein. The straw restraining passage defines a reduced cross-sectional area of the chamber, and the pouch is manufactured with a weakened portion on an upper portion of the pouch, whereby the weakened portion can be torn by a user, thus enabling the internal straw to emerge, due to the buoyancy of the straw, from the interior of the pouch. In providing a sealed bottom edge to the liquid pouch, a bottom rim is formed, wherein the pouch can stand in an upright position on a horizontal surface upon the bottom rim.
