ABSTRACT:
This invention is a spray bottle having unique flow passages that when wetted provide restrictions that allow only liquid to be dispensed either in the upright or inverted position. A gas rejection device of numerous configurations are incorporated into the spray bottle with minimum or no additional cost to manufacturing the spray bottle. Liquid rejection devices permit air to replace the dispensed liquid in order to prevent the collapse of the plastic bottle without leaking liquid in the inverted position.
