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