A tubular bag with cap closure for the accommodation of fluid foodstuffs, wherein the base of the bag is constructed especially as a standing base and is welded or sealed fluid-tight with the bag as a separate component along the base-end bag edge, wherein the tubular part of the bag is manufactured from a single cut of film, especially a cut of laminated film, the longitudinal edges of which are sealed one over the other to form a "lap seal" (inner/outer seal) or alternatively constructed as a "fin seal" (inner/inner seal). A cap closure that is part of a relatively stiff cover is welded or sealed fluid-tight with the upper or closure-end bag edge. The tubular bag according to the invention has an enhanced filling capacity and improved stability.

What is claimed is: 1. A tubular bag with cap closure for the accommodation of fluid foodstuffs, wherein the base of the bag is constructed as a standing base and is welded or sealed fluid-tight with the bag as a separate component along the inside surface of the base-end bag edge, and wherein the cap closure is part of a relatively stiff cover, which is fluid-tight welded or sealed along the inside surface of the upper or closure-end bag edge, and wherein the cover and the standing base each have at least one indentation with a circumferentially extending width so that the tubular bag can be fitted with the cover and base in such a way that the respectively designated circumferential edge of the tubular bag sits snugly against the cover and the base over the entire circumference, wherein the width of the indentation does not extend continuously around the circumference of the cover or base, and wherein a seam of the tubular bag is not aligned with at least one of the indentations. 2. A bag according to claim 1, wherein the standing base comprises a relatively rigid disc with vertical circumferential edge. 3. A bag according to claim 1, wherein the tubular part of the bag can be plastically deformed within a mold to form a durable profile. 4. A bag according to claim 1, wherein the cover has a vertical circumferential edge with at least two circumferential ribs arranged in axial distance from one another, with which the designated edge of the tubular part of the bag can be welded or sealed. 5. A bag according to claim 1, wherein the cap closure comprises a screw cap. 6. A bag according to claim 1, wherein the cover is constructed to form a circular, oval or acute oval shape. 7. A bag according to claim 1, wherein said indentation has a radially extending depth and an axially extending length. 8. A tubular bag with cap closure for the accommodation of fluid foodstuffs, wherein the base of the bag is constructed as a standing base and is welded or sealed fluid-tight with the bag as a separate component along the inside surface of the base-end bag edge, and wherein the cap closure is part of a relatively stiff cover, which is fluid-tight welded or sealed along the inside surface of the upper or closure-end bag edge, and wherein the cover has at least one indentation with a circumferentially extending width so that the tubular bag can be fitted with the cover in such a way that the respectively designated circumferential edge of the tubular bag sits snugly against the cover over the entire circumference, wherein the width of the indentation does not extend continuously around the circumference of the cover, and wherein a seam of the tubular bag is not aligned with the indentation. 9. A bag according to claim 8, wherein the tubular part of the bag can be plastically deformed within a mold to form a durable profile. 10. A bag according to claim 8, wherein the cover has a vertical circumferential edge with at least two circumferential ribs arranged in axial distance from one another, with which the designated edge of the tubular part of the bag can be welded or sealed. 11. A bag according to claim 8, wherein the base is constructed from a relatively stiff or rigid or alternatively flexible disc, the circumferential edge of which is welded or sealed with the circumferential edge of the tubular part of the bag, which edge is deformed at its base somewhat radially towards the outside. 12. A bag according to claim 8, wherein the cap closure comprises a screw cap. 13. A bag according to claim 8, wherein the cover is constructed to form a circular, oval or acute oval shape. 14. A bag according to claim 8, wherein the bag is sealed at its base by a base seam. 15. A bag according to claim 8, wherein said indentation has a radially extending depth and an axially extending length. 16. A bag according to claim 8, wherein the standing base comprises a V or W-shaped folded cut of film, wherein the latter can be inserted into the inside of the bag by means of a blade engaged from below and can be welded or sealed with the lower bag edge to form a roughly U-shaped welded or sealed seam. 17. A bag according to claim 16, wherein prior to insertion into the tubular part of the sealed bag, the base is manufactured from a rectangular or square cut of film in such a way that the cut of film is folded and sealed along the superimposed, now shorter edges. 18. A bag according to claim 17, wherein the presealed base is inserted inside out into the tubular part of the sealed bag and is sealed with its circumferential and base edge producing a tubular stand-up bag, wherein the short sealed edges of the base are located within the stand-up bag. 19. A tubular bag with cap closure for the accommodation of fluid foodstuffs, wherein the base of the bag is constructed as a standing base and is welded or sealed fluid-tight with the bag as a separate component along the inside surface of the base-end bag edge, and wherein the cap closure is part of a relatively stiff cover, which is fluid-tight welded or sealed along the inside surface of the upper or closure-end bag edge, and wherein the standing base has at least one indentation with a circumferentially extending width so that the tubular bag can be fined with the base in such a way that the respectively designated circumferential edge of the tubular bag sits snugly against the base over the entire circumference, wherein the width of the indentation does not extend continuously around the circumference of the base, and wherein a seam of the tubular bag is not aligned with the indentation. 20. A bag according to claim 19, wherein the standing base comprises a relatively rigid disc with vertical circumferential edge. 21. A bag according to claim 19, wherein the tubular part of the bag can be plastically deformed within a mold to form a durable profile. 22. A bag according to claim 19, wherein the cap closure comprises a screw cap. 23. A bag according to claim 19, wherein the cover has a vertical circumferential edge with at least two circumferential ribs arranged in axial distance from one another, with which the designated edge of the tubular part of the bag can be welded or sealed. 24. A bag according to claim 23, wherein said indentation has a radially extending depth and an axially extending length. 25. A bag according to claim 19, wherein the bag on both aides in the head area is pulled inwards diametrically to the longitudinal axis to form a W-fold. 26. A bag according to claim 25, wherein the W-fold is fixed in the area of a head seam by reciprocal sealing. 27. A bag according to claim 25, wherein the cover is constructed as a flat molded piece with a closure opening and is sealed in place between the W-folds and the head seam. 28. A bag according to claim 27, wherein the molded piece is constructed to form a circular, oval or acute oval shape.
