<p>A fluid dispensing closure (10) which incorporates a dispensing valve (40) to control fluid flow through the closure and a vent passageway (62) to vent air into the container (10) as necessary. The closure (10) includes a dispensing spout (20) capable of mating engagement with a receiving container. The dispenser spout (20) has a fluid passageway (22) with a resilient valve (40) made from an elastomeric material seated therein. The vent passageway (62) formed in the closure is selectively sealed by a grommet (70) depending upon the vacuum created within the container as the fluid is being dispensed from the container. A removable overcap (90) sealingly covers the dispensing spout to capture any fluid leakage.</p> |
