ABSTRACT:
A handheld dispenser includes a collapsible liquid container, a liquid pump, an air pump, and a mixing chamber. The liquid pump provides a collapsible liquid chamber collapsed from an expanded volume to a compressed volume to expel liquid from the collapsible liquid chamber into the mixing chamber. The air pump provides a collapsible air chamber collapsed from an expanded volume to a compressed volume to expel air from the collapsible air chamber into the mixing chamber. The liquid pump and air pump are secured to the collapsible liquid container so as to be capable of being manipulated with one hand. Air expelled into the mixing chamber mixes with liquid expelled into the mixing chamber so that a mixed product is dispensed.
