ABSTRACT:
A spray dispenser includes an outer body, a product bag containing a liquid product disposed in the outer body, and a valve disposed at an upper end of the outer body. An elastic energy-storing member is disposed below the bag, and an energizing member is disposed below the energy-storing member for compressing the latter. The energizing member is raised by rotation of a threaded post which extends through the energizing member in threaded connection therewith. The post comprises a plurality of screws telescopingly arranged to define separate stages of operation, whereby the screws move from a retracted relationship to an extended relationship as the energizing member moves upwardly.
