A closing element for a packaging for receiving liquid or paste-like material, especially for film bags, and having a closable spout member, a weld member adjoining the closable spout member, and an outlet channel which extends through the weld member and the spout member, and also a film bag comprising such a closing element. To improve the pouring characteristics and for an easier emptying of the contents of the bag, the outlet channel in the weld member extends at least in part in funnel-like manner towards the spout member.

We claim: 1. A closing element for a packaging for receiving liquid or paste-like material, the closing element comprising: a closable spout member; a weld member connected to said closable spout member, the weld member having a longitudinal extension and a width extension, the longitudinal extension being greater than the width extension; and an outlet channel having a central axis, wherein the outlet channel and the central axis extend through said weld member and said spout member, the outlet channel in said weld member having an outlet width being substantially constant and an outlet length that gradually decreases toward the spout member until the outlet length is substantially identical to the diameter of the outlet channel in the spout member, the outlet length being greater than the outlet width in the weld member, wherein the outlet width in the weld member is substantially equal to the outlet width in the spout member; wherein said outlet channel in said weld member extends at least in part in funnel-like manner towards said spout member; wherein said outlet channel in said spout member has a substantially cylindrical shape having a diameter that is substantially constant wherein the diameter corresponds to the constant width of the weld member. 2. The closing element according to claim 1, wherein said outlet channel in said weld member extends in funnel-like manner at an angle (γ) of 20° to 85° relative to the longitudinal axis (L) of said closing element. 3. The closing element according to claim 1, said outlet channel having a parallel portion at least partially substantially parallel to the longitudinal axis of said closing element, the parallel portion being distal to the spout member, and a tapered portion which tapers towards said spout member, the tapered portion being proximal to the spout member. 4. The closing element according to claim 1, wherein said outlet channel in said spout member has the shape of a hollow cylinder. 5. The closing element according to claim 1, wherein said spout member can be closed with a cap via a bayonet lock. 6. The closing element according to claim 1, wherein said spout member includes an end that faces away from the weld member, the end having a smooth surface for a mouthpiece. 7. The closing element according to claim 6, wherein: said spout member can be closed with a cap via a bayonet lock; and said smooth surface is positioned above said bayonet lock. 8. The closing element according to claim 1, wherein said weld member comprises attached beads. 9. The closing element according to claim 8, wherein at least two beads extend spaced-apart from the upper and lower edges of said weld member. 10. A film bag comprising the closing element of claims 1. 11. The film bag of claim 10 wherein the closing element is welded or adhesively fixed between a first side wall and a second side wall of said film bag. 12. The film bag of claim 10, wherein: the film bag includes a first shoulder and a second shoulder; and the closing element is disposed between the first shoulder and the second shoulder, the first shoulder and the second shoulder being welded off from an outer edge of the film bag obliquely towards the closing element by one or more weld seams. 13. The film bag of claim 12, wherein: the longitudinal extension of the weld member includes a lower edge that faces the interior of the film bag, the lower edge located adjacent to a side edge to define a tip; and the weld seams meet at the tip of the weld member. 14. A closing element for a packaging for receiving liquid or paste-like material, the closing element comprising: a closable spout member; a weld member connected to said closable spout member, the weld member having a first side and a second side meeting at an acute angle; and an outlet channel, which extends through said weld member and said spout member; wherein said outlet channel in said weld member extends at least in part in a funnel-like manner towards said spout member, wherein the outlet channel has a length and a width within the weld member, the length being greater than the width, wherein the length gradually decreases toward the spout member until the length is substantially identical to the diameter of the outlet channel in the spout member and the width of the outlet channel in the weld member remains the same within the weld member, wherein the outlet width in the weld member is substantially equal to the outlet width in the spout member; wherein the outlet channel in said spout member has a substantially cylindrical shape having a diameter that is substantially constant and corresponds to the width of the outlet channel in the weld member and in the spout member. 15. The closing element according to claim 2, said outlet channel having a parallel portion at least partially substantially parallel to the longitudinal axis of said closing element, the parallel portion being distal to the spout member, and a tapered portion which tapers towards said spout member, the tapered portion being proximal to the spout member. 16. The closing element according to claim 2, wherein said outlet channel in said spout member has the shape of a hollow cylinder. 17. The closing element according to claim 2, wherein said spout member can be closed with a cap via a bayonet lock. 18. The closing element according to claim 2, wherein said spout member includes an end that faces away from the weld member, the end having a smooth surface for a mouthpiece. 19. The film bag of claim 11, wherein: the film bag includes a first shoulder and a second shoulder; and the closing element is disposed between the first shoulder and the second shoulder, the first shoulder and the second shoulder being welded off an outer edge of the film bag obliquely towards the closing element by one or more weld seams. 20. The film bag of claim 11 wherein the closing element, is disposed proximate a substantially top center position of the film bag. 21. The film bag of claim 11 wherein the closing element is disposed proximate a substantially top corner position of the film hag. 22. The film bag of claim 19, wherein: the longitudinal extension of the weld member includes a lower edge that faces the interior of the film bag, the lower edge located adjacent to a side edge to define a tip; and the weld seams meet at the tip of the weld member.
