8. A method of introducing fluid into a container through a dispensing assembly, the method comprising the steps of:

moving fluid into the container through a spout fixedly attached to the container; and

affixing a cap to the spout, the cap having a first collar defining a cap retention element, a second collar spaced radially apart from the first collar, an end wall extending radially connecting the first collar and the second collar, wherein the first collar and second collar extend approximately the same distance from the end wall, and a gap defined radially between the first collar and the second collar, and a cap wall spaced radially away from the first collar and the second collar and located entirely on the side of the end wall from which the first collar and second collar extend, wherein the first collar, second collar, and cap wall are all perpendicular to the end wall, the step of affixing the cap to the spout including receiving the spout within the gap defined between the first collar and the second collar, contacting the spout with the first collar and the second collar, and contacting the cap retention element with a spout retention element disposed on the spout.

9. The method of claim 8 , further comprising inserting a plug into an opening defined by the cap wall such that a fluid-tight seal is formed between the plug and the cap wall, wherein the plug includes a cylindrical wall that is received in the opening of the cap wall.

10. A method of dispensing fluid from a collapsible bag using a dispensing assembly, the dispensing assembly having a spout fixedly attached to the collapsible bag and a cap attached to the spout, the cap having a first collar defining a cap retention element, a second collar spaced radially apart from the first collar, an end wall extending radially and connecting the first collar and the second collar, wherein the first collar and second collar extend approximately the same distance from the end wall, and a gap defined radially between the first collar and the second collar, and a cap wall spaced radially away from the first collar and the second collar and located entirely on the side of the end wall from which the first collar and second collar extend, wherein the first collar, second collar, and cap wall are all perpendicular to the end wall, the spout being disposed within the gap between the first collar and the second collar and being in contact with the first collar and the second collar, the spout having a retention element, wherein the engagement between the cap retention element and the spout retention element occurs entirely within the gap, the method comprising:

opening the dispensing assembly such that the fluid is permitted to move from the collapsible bag through the spout and out of the dispensing assembly; and

actuating movement of the fluid from the collapsible bag through and out of the dispensing assembly.

11. The method of claim 10 , wherein the step of opening the dispensing assembly includes removing a plug from an opening defined in the cap wall such that a fluid-tight seal between the plug and the cap does not exist, the method further comprising the step of inserting a dispensing component into the opening.

12. The method of claim 10 , wherein the step of opening the dispensing assembly includes applying a de-coupling force to the cap such that the cap is separated from the spout, the method further comprising the step of affixing a dispensing component to the spout.

13. A fitment for use on a collapsible bag for dispensing of fluids from the collapsible bag, the fitment comprising:

a spout having an exterior surface defining a spout retention element, the spout further having a flange configured to engage with the collapsible bag; and

a cap having:

a first collar having a cap retention element thereon;

a second collar;

an end wall extending radially and connecting the first collar and the second collar, wherein the first collar and second collar extend approximately the same distance from the end wall; and

a cap wall radially disposed on the cap and located entirely on the side of the end wall from which the first collar and second collar extend, wherein the first collar, second collar and cap wall are all perpendicular to the end wall, the cap wall defining an opening extending through the cap, and

wherein the cap defines a gap radially between the first collar and the second collar; and

wherein the cap retention element is configured to releasably engage with the spout retention element,

wherein the cap is configured to receive the spout in the gap defined between the first collar and the second collar and to contact the spout with the first collar and with the second collar when the spout is within the gap,

wherein the engagement between the cap retention element and the spout retention element occurs entirely within the gap, and

wherein the cap retention element is configured to contact the spout retention element such that the cap is affixed to the spout.

14. The fitment of claim 13 , wherein the cap is configured to be removed from the spout upon application of a predetermined de-coupling force.

15. The fitment of claim 13 , wherein the cap includes a plurality of cap retention elements.

16. The fitment of claim 13 , wherein the fitment further includes a plug configured to be removably inserted into the opening, such that when the plug is in the opening, a fluid-tight seal is formed between the plug and the cap, wherein the plug includes a cylindrical wall that is received in the opening of the cap wall.

17. The fitment of claim 13 , further including a valve configured to contact the second collar of the cap and configured to receive the fluid therethrough.

18. The fitment of claim 17 , further comprising a valve lock ring configured to be disposed between the valve and the spout.

19. The fitment of claim 18 , wherein the valve lock ring is configured to prevent the valve from permitting the fluid from the collapsible bag from flowing through the valve.
