Patent ID: 8517061

Claim:
A process for assembling a fitment on to a filled or unfilled container, comprising the steps as follows: (I) assembling a generally cylindrical internal slider valve into a generally cylindrical external valve body to form a valve body assembly into a primary seal position; (II) putting a cap on said external valve body of said valve body assembly; (III) assembling said assembly of said cap and said valve body assembly on to a generally cylindrical spout in a pre-cap position to form a fitment assembly; and (IV) affixing the assembly of Step (III) to said container wherein said fitment assembly comprises said fitment for attachment to said container for holding and dispensing a fluid, wherein said fitment has said spout attached thereto, said fitment further comprises said external valve body movable to a fixed position within said spout; and said internal valve body movable axially within said external valve body, said internal valve body 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, said internal valve body movable between closed and open positions by insertion of a dispensing connector into said external valve body adjacent said internal valve body, said internal valve body being biased toward the closed position; and 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; 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; and 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.
