A collar for a dispensing connector and a fitment assembly are disclosed. The connector collar engages a valved fitment for a container for holding and dispensing fluid. The fitment includes a spout connected to the container and a sliding internal valve body and an external valve body securely positioned within the spout. The connector collar has a fitment end mateable with the fitment so as to compress the top edge of the external valve body so as to form a seal between the external valve body and the dispensing connector.

1. A fitment assembly comprising: a fitment for attachment to a container for holding and dispensing a fluid and having a generally cylindrical spout attached thereto, the fitment comprising 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, the internal valve body movable between a closed position operable to prevent the flow of fluid through the fitment and an open position operable to allow the flow of fluid through the fitment, the internal valve body movable between closed and open positions by insertion of a dispensing connector into the external valve body adjacent the internal valve body, the internal valve body being biased toward the closed position; and a collar for attachment to the dispensing connector and for releasable coupling to the fitment, wherein when coupled to the fitment the collar compressively engages the external valve body to form a seal between the external valve body and the dispensing connector; wherein said collar comprises a generally cylindrical collar body for engagement about the dispensing connector and a fitment end for coupling to the fitment;wherein the collar comprises a compression flange connected to the collar body at the fitment end for engaging and compressing a top edge of the external valve body; andwherein the fitment end comprises an external descending flange and an internal descending flange connected to the base of the collar body, the external descending flange and the internal descending flange being concentric and spaced from each other. 2. The fitment assembly of claim 1, wherein the internal wall of the external descending flange is threaded for engagement with an external threaded surface of the spout. 3. The fitment assembly of claim 1, wherein the external descending flange and internal descending flange are spaced from each other so as to form a receiving space and a portion of the spout is receivable in the receiving space without active engagement of the exterior of the spout. 4. The fitment assembly of claim 3, wherein the receiving space has smooth walls. 5. The fitment assembly of claim 1, wherein the external descending flange ex-tends about the entire periphery of the collar body. 6. The fitment assembly of claim 1, comprising a plurality of discrete external descending flanges about the periphery of the collar body. 7. The fitment assembly of claim 1, wherein an inside surface of the internal descending flange is engageable with an outside surface of the external valve body. 8. The fitment assembly of claim 7, wherein the inside surface of the internal descending flange is threadably engageable with an outside surface of the external valve body. 9. The fitment assembly of claim 1, wherein the compression flange is connected to an internal surface of the internal descending flange for engaging and compressing a top edge of the external valve body. 10. The fitment assembly of claim 1, further comprising the spout.
