ABSTRACT:
A nestable spout assembly for dispensing liquid products from cans and pails. A molded plastic spout in extended position has an enlarged flexible lower wall portion joined to a relatively rigid externally threaded upper wall portion. A peripheral sealing channel is disposed about the base of the lower wall portion for securing to a container wall opening neck by means of an overlying metal crimping ring. A tear out diaphragm is recessed within the spout upper wall portion above the spout thread and provided with an integrally molded ring pull for removal. A circumferentially enlarged plastic reclosing cap threadedly engages the spout upper wall portion and also interlockingly engages the metal crimping ring with the spout in nested position to close off the annular spout void against contamination. A separate generally cup shaped pouring vent is included in the spout assembly to facilitate smooth, surge free, pouring. The vent has a generally cylindrical outer baffle wall, an annular bottom wall and a generally cylindrical inner liquid passageway. A series of air entry apertures are formed in the upper portion of the outer baffle wall which terminates at its uppermost end in a circumferential lip adapted for seating within the spout sealing channel.
