1. An adaptor used in a fitment valve assembly, said adaptor comprising: (A) an outer ring collar having a top and a bottom, and an outer and an inner surface, wherein said outer ring collar has threads moulded into said outer surface of said outer ring collar, andwherein said outer ring collar has
1. An adaptor used in a fitment valve assembly, said adaptor comprising: (A) an outer ring collar having a top and a bottom, and an outer and an inner surface, wherein said outer ring collar has threads moulded into said outer surface of said outer ring collar, andwherein said outer ring collar has threads moulded into said lower inner surface of said outer ring collar;(B) a flange moulded to the bottom of said outer ring collar;(C) an interior ring collar having a top and a bottom, and an outer and an inner surface moulded in adjacent relationship to said outer ring collar near the top of said interior ring collar, wherein said outer surface of the top part of said inner ring collar and the top part of said inner surface of said outer ring collar forms a U-shaped channel for receiving a part of said fitment valve assembly,wherein the lower part of said outer surface of said interior ring collar and the lower part of said inner surface of said outer ring collar form a lower U-shaped channel for receiving a part of said fitment valve assembly, andwherein said outer surface of said interior ring collar having a groove around said bottom of said interior ring collar for positioning an O-ring being part of said fitment valve assembly;(D) an inverted dome structure moulded toward the bottom of said inner surface of said interior ring collar defining at least one opening for the flow of fluid there-through;(E) a groove for an O-ring moulded in said inner surface of said interior ring collar above said dome structure;(F) a lip moulded onto said bottom of said interior ring collar for forming a seal with said fitment valve assembly; and(G) a groove for an O-ring moulded in said outer surface at the bottom of said interior ring collar. 2. The adaptor of claim 1, having 4-8 openings in the inverted dome structure. 3. The adaptor of claim 1, wherein said adaptor is a moulded plastic or elastomer. 4. The adaptor of claim 3, wherein said adaptor is moulded polyurethane. 5. A fitment valve assembly comprising: (A) a fitment for attachment to a container for holding and dispensing a fluid, wherein said container has a generally cylindrical spout attached thereto,wherein said fitment comprises a generally cylindrical external valve body movable to a fixed position within the spout and a generally cylindrical internal valve body movable axially within the external valve body,wherein said internal valve body is movable between a closed position operable to prevent the flow of fluid through said fitment and an open position operable to allow the flow of fluid through said fitment,wherein said internal valve body is movable between closed and open positions by insertion of a dispensing connector into said external valve body adjacent said internal valve body, wherein said internal valve body being is biased toward the closed position; and(B) a collar for attachment to said dispensing connector and for releasable coupling to said fitment, wherein when coupled to said fitment said collar compressively engages said external valve body to form a seal between said external valve body and said dispensing connector and further comprises said adaptor of claim 1 positioned between said fitment and said cylindrical spout of said container containing fluid. 6. The fitment assembly of claim 5, wherein said adaptor is threadably engaged with said fitment and said cylindrical spout. 7. A process for dispensing fluid from a container, wherein said container has a spout attached to it, and wherein said spout is in contact with a fitment valve through an adaptor described claim 1. 8. The process as described in claim 7, wherein said adaptor has 4-8 openings in the inverted dome structure. 9. The process as described in claim 7, wherein said adaptor is a moulded plastic or elastomer. 10. The process as described in claim 7, wherein said adaptor is moulded polyurethane. 11. The process as described in claim 7, wherein said adaptor, is threadably engaged with said fitment and said cylindrical spout.
