1. A collapsible fluid dispensing package for dispensing fluid by relative pressure present in the collapsible fluid dispensing package, the collapsible fluid dispensing package comprising:

a container for containing the fluid, and the container comprising at least one seal edge,

a valve fitment sealed to the at least one seal edge of the container; the valve fitment comprising a compressible wedge-like spout,

the valve fitment further comprises a sealing base in sealed engagement with the container at the at least one seal edge,

the compressible wedge-like spout is located within a passage formed in or through the sealing base,

the passage is hermetically closed from an exterior by at least one flexible wall of the container sealed onto the sealing base,

the sealing base comprises a fluid flow guiding member comprising a tube comprising a first end positioned in an interior of the sealing base to fluidly connect with the passage, the tube further comprising a second end extending from the sealing base into the exterior of the container, and the compressible wedge-like spout is positioned in the interior of the sealing base between the first end of the tube and a side of the sealing base opposite from the first end of the tube, and

wherein at least one side of the sealing base has an opening providing access into the passage, the opening being closed by the at least one flexible wall of the container, such that the at least one flexible wall of the container defines a wall of the passage over the opening.

2. The collapsible fluid dispensing package according to claim 1 , wherein the sealing base comprises sealing surfaces for sealing with the container at the at least one seal edge, and the compressible wedge-like spout is placed in the passage in recess relative to sealing surfaces of the sealing base.

3. The collapsible fluid dispensing package according to claim 1 , wherein the passage extends in a direction substantially orthogonal to a general plane of extension of the at least one seal edge of the container.

4. The collapsible fluid dispensing package according to claim 1 , wherein the sealing base is formed as a boat-type fitment portion.

5. The collapsible fluid dispensing package according to claim 1 , wherein the compressible wedge-like spout comprises a free tapered end which comprises a lip line oriented in a direction of extension of the passage across the sealing base that is capable of opening or enlarging to form an opening.

6. The collapsible fluid dispensing package according to claim 5 , wherein the lip line is initially hermetically closed or sealed before use.

7. The collapsible fluid dispensing package according to claim 5 , wherein the compressible wedge-like spout comprises at least one pressure-bearing surface.

8. The collapsible fluid dispensing package according to claim 1 , wherein the fluid flow guiding member protrudes from the sealing base.

9. The collapsible fluid dispensing package according to claim 8 , wherein the second end of the tube comprises a fluid delivery outlet.

10. The collapsible fluid dispensing package according to claim 1 , wherein the valve fitment is formed of a single piece made integrally of the same material.

11. The collapsible fluid dispensing package according to claim 1 , wherein the fluid is a foodstuff, and an interior of the collapsible fluid dispensing package is aseptically treated.

12. A valve fitment for a collapsible fluid dispensing package for dispensing fluid by relative pressure present in the collapsible fluid dispensing package, the valve fitment comprising:

a compressible wedge-like spout;

a sealing base arranged for sealing engagement with a container at a seal edge;

wherein the compressible wedge-like spout is located within a passage formed through the sealing base,

the sealing base is of greater rigidity than the compressible wedge-like spout, the sealing base comprises a fluid flow guiding member comprising a tube comprising a first end positioned in an interior of the sealing base to fluidly connect with the passage, the tube further comprising a second end extending from the sealing base into an exterior of the container, and the compressible wedge-like spout is positioned in the interior of the sealing base between the first end of the tube and a side of the sealing base opposite from the first end of the tube,

the passage is hermetically closed from the exterior by at least one flexible wall of a container sealed onto the sealing base, and

wherein at least one side of the sealing base has an opening providing access into the passage, the opening being closed by the at least one flexible wall of the container, such that the at least one flexible wall of the container defines a wall of the passage over the opening.

13. The valve fitment according to claim 12 , wherein the sealing base comprises sealing surfaces for sealing with the container at the seal edge, the compressible wedge-like spout is placed in the passage in recess relative to the sealing surfaces of the sealing base.

14. The collapsible fluid dispensing package according to claim 1 , wherein the sealing base comprises seal surfaces forming transversal ridges extending on each side of the sealing base.

15. The collapsible fluid dispensing package according to claim 14 , wherein the transversal ridges extend orthogonally from a median portion of a wall of the container extending longitudinally along a dimension of the valve fitment and in a median plane of the at least one seal edge of the container.

16. The collapsible fluid dispensing package according to claim 14 , wherein the transversal ridges comprising central ridges, portions of the central ridges delimit the passage for access to the compressible wedge-like spout, and the central ridges extend beyond the compressible wedge-like spout in an orthogonal direction.
