Abstract
Abstract A pouring fitment and closure assembly comprising a central tubular body having at its interior most extremity an enlarged circular disk-like plate with a sharpened edge, the central tubular portion then opening up into a rib-formed plurality of ports to an interior plenum terminated at the outside end by an annular inwarldy protruding sharpened projection interior to the plenum forming a first sharp dripless and sealing edge. The central tubular body flairs outward in a skirt to join a flat annular radial sealing ring at its top which in turn terminates in a larger circular edge to form an acute angle, the second dripless edge.

Claim 11
Dependent Claim
99 words
The pouring fitment as defined in claim 9 wherein said closure defines a cup-like structure having a cylindrical wall and circular bottom, said cylindrical wall threaded in their interior periphery proximate the opening, and including an annular bead protruding inwardly on the interior surface of said cylindrical wall proximate the circular bottom, said inwardly protruding annular bead adapted to hold in place said pouring fitment after said pouring fitment outward extending lugs have been pushed past said closure cylindrical wall annular bead whereby said pouring fitment is kept captive in said closure prior to capping the associated container opening.
Claim 12
Dependent Claim
37 words
