Abstract
A press-to-open dispensing closure is provided for the mouth of a container. It includes a closure body and a nozzle assembly carried by the closure body. The closure body has a deck extending across a portion of the container top, and the deck defines a port through which communication with the container interior is established. The nozzle assembly includes a forwardly projecting dispensing nozzle and a rearwardly projecting actuating member above the deck. The nozzle assembly is pivotably supported in the closure body to accommodate pivoting movement between an open and a closed position. In one embodiment, spring members are provided on the closure body and project upwardly for resiliently biasing the nozzle assembly toward the closed position.
