Slider valve fitment and collar
View Patent ↗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 said dispensing connector and a fitment end for coupling to said fitment;
wherein said collar comprises a compression flange connected to the collar body at said fitment end for engaging and compressing a top edge of said external valve body;
wherein the fitment end comprises an external descending flange and an internal descending flange connected to said base of said collar body, said external descending flange and said internal descending flange being concentric and spaced from each other; and
wherein said fitment assembly is made from a synthetic resin material.
2. The fitment assembly of claim 1 , further comprising the spout.
3. The fitment assembly as recited in claim 2 , wherein said spout is made from a synthetic material.
4. The fitment assembly as recited in claim 2 , wherein at least one part of said fitment assembly and said spout is made from polypropylene.
5. The fitment assembly and spout as recited in claim 2 , wherein said internal valve body and/or said external valve body is made from polypropylene.
6. The fitment assembly of claim 1 , wherein said synthetic material is melded.
7. The fitment assembly of claim 1 , wherein said synthetic material is the same as that for the container.
8. The fitment assembly of claim 1 , wherein said synthetic material is selected from the group consisting of polypropylene, high-density polyethylene, polystyrene, and nylon.
9. The fitment assembly as recited in claim 1 , wherein said fitment assembly is made from polypropylene.
10. The fitment assembly as recited in claim 1 , wherein at least one part of said fitment assembly is made from polypropylene.
11. The fitment assembly as recited in claim 1 , wherein said internal valve body and/or said external valve body is made from polypropylene.
