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.

1. A liquid pouch comprising:a pair of opposed side walls formed from sheet material and having a sealed mutual top edge, bottom edges each sealed to a bottom portion, and opposed sealed mutual side edges to form an enclosed compartment capable of containing a liquid product; a straw-restraining passage formed internally of said compartment between the opposed side walls thereof, the straw-restraining passage defining a reduced cross-sectional area of the enclosed compartment, said straw-restraining passage being immediately adjacent a weakened portion of one of the sealed side edges and disposed substantially parallel to said one of said sealed side edges of said pouch, wherein the straw-restraining passage extends from said sealed mutual top edge and terminates a mid-length area of said pouch, said straw-restraining passage being shorter than said sealed side edges; and a straw held loosely captive in the straw-restraining passage but axially displaceable therein, whereby the weakened portion can be torn by a user, thus enabling the straw to emerge, due to buoyancy of the straw, from the enclosed compartment. 2. The flexible pouch according to claim 1, wherein, in sealing the bottom edges of the pouch to a bottom portion, a bottom rim is formed, wherein the pouch can stand in an upright position on a horizontal surface upon the bottom rim.3. The flexible pouch according to claim 2, wherein a flexible gusset is provided at an end of the enclosed compartment between the opposed side walls, the flexible gusset being upwardly recessed from and contained within a perimeter of the bottom rim.4. The flexible pouch according to claim 3, wherein the enclosed compartment is formed substantially between the opposed side walls, and the flexible gusset.5. The pouch according to claim 1, wherein the weakened portion is a “V” shaped indented notch formed on the upper portion of one of the sealed side edges of the pouch, and at a top end of said straw-restraining passage.6. The pouch according to claim 1, wherein the straw restraining passage is comprised by a raised portion of the sheet material having a slightly higher elevation than a substantial portion of a remainder of said sheet material, the raised portion being formed upon the sheet material of each of said opposed side walls, whereby when the opposed side walls are sealed together so as to form the enclosed compartment, the raised portion of each opposing side wall contacts each other and are cooperatively placed in alignment so as to define the straw-restraining passage within the enclosed compartment.7. The pouch according to claim 1, wherein said sheet material is a foil laminate sheet material.8. The pouch according to claim 7, wherein said foil laminate sheet material is a non-transparent sheet material in at least a substantial portion of said pouch.9. Tho pouch according to claim 1, wherein the sealed side edges of the pouch are curved to resemble an hourglass shape.10. The pouch according to claim 1, wherein a diameter of the weakened portion of the pouch is greater than a diameter of the straw.11. The pouch according to claim 1, wherein the straw in said straw-restraining passage lies in a cross-directional angle, whereby a top portion of the straw lies in the straw-restraining passage and a lower portion of the straw lies in the enclosed compartment beyond the straw-restraining passage.12. The pouch according to claim 1, whereby the weakened portion is provided on an upper portion of one of the sealed side edges of the pouch.13. Apparatus comprising:a pair of opposed side walls formed from sheet material and having a sealed mutual top edge, bottom edges, and side edges to form an enclosed compartment, capable of containing a liquid product; a straw-restraining passage within said compartment between the pair of opposed side walls thereof, said straw-restraining passage defined by a raised portion having a first side and an opposite second side extending toward the bottom edges, wherein the first side of said raised portion defines the straw-restraining passage and the opposite second side is exposed to the compartment, said straw-restraining passage being immediately adjacent a weakened portion of one of the sealed side edges and disposed substantially parallel to said one of said sealed side edges of said pouch, therein the straw-restraining passage extends from said sealed mutual top edge and terminates in a mid-length area of said pouch, said straw-restraining passage being shorter than said sealed side edges; and a straw held loosely captive in the straw-restraining passage but axially displaceable therein, whereby the weakened portion can be torn by a user, thus enabling the straw to emerge, due to buoyancy of the straw, from the enclosed compartment. 14. The flexible pouch according to claim 13, wherein, in sealing the bottom edges of the pouch to a bottom portion, a bottom rim is formed, wherein the pouch can stand in an upright position on a horizontal surface upon the bottom rim.15. The flexible pouch according to claim 14, wherein a flexible gusset is provided at an end of the enclosed compartment between the opposed side walls, the flexible gusset being upwardly recessed from and contained within a perimeter of the bottom rim.16. The flexible pouch according to claim 15 wherein the enclosed compartment is formed substantially between the opposed side walls, and the flexible gusset.17. The pouch according to claim 13, wherein the weakened portion is a “V” shaped indented notch formed on the upper portion of one of the sealed side edges of the pouch, and at a top end of said straw-restraining passage.18. The pouch according to claim 13 wherein the raised portion includes a slightly higher elevation than a substantial portion of a remainder of said sheet material, the raised portion being formed upon the sheet material of each of said opposed side walls, whereby when the opposed side walls are sealed together so as to form the enclosed compartment, the raised portion of each opposing side wall contacts each other and are cooperatively placed in alignment so as to define the straw-restraining passage within the enclosed compartment.19. The pouch according to claim 13, wherein said sheet material is a foil laminate sheet material.20. The pouch according to claim 19, wherein said foil laminate sheet material is a non-transparent sheet material in at least a substantial portion of said pouch.21. The pouch according to claim 13, wherein the sealed side edges of the pouch are curved to resemble an hourglass shape.22. The pouch according to claim 13, wherein a diameter of the weakened portion of the pouch is greater than a diameter of the straw.23. The pouch according to claim 13, wherein the straw in said straw-restraining passage lies in a cross-directional angle, whereby a top portion of the straw lies in the straw-restraining passage and a lower portion of the straw lies in the enclosed compartment beyond the straw-restraining passage.24. The pouch according to claim 13, whereby the weakened portion is provided on upper portion of one of the sealed side edges of the pouch.
