Claim:
A handheld dispenser for dispensing air mixed with a liquid, the handheld dispenser comprising: a collapsible liquid container holding a liquid; a mixing chamber; a liquid dome pump including a resilient liquid dome and a liquid pump base defining a collapsible liquid chamber communicating with said mixing chamber through a liquid outlet path, wherein said collapsible liquid chamber is manipulated between an expanded volume and a contracted volume by pressing on said resilient liquid dome toward said liquid pump base, said collapsible liquid chamber communicating with said liquid in said liquid chamber through a liquid valve; and an air dome pump including a resilient air dome and an air pump base defining a collapsible air chamber communicating with said mixing chamber through an air outlet path, wherein said collapsible air chamber is manipulated between an expanded volume and a contracted volume by pressing on said resilient air dome toward said air pump base, said collapsible air chamber communicating with air outside the dispenser through an air valve, said collapsible liquid chamber and said collapsible air chamber being secured to said collapsible liquid container so as to be capable of manipulation with one hand; wherein a portion of said liquid in said collapsible liquid container is drawn into said collapsible liquid chamber upon expansion of said collapsible liquid chamber from said contracted volume to said expanded volume, and a portion of said liquid within said collapsible liquid chamber is expelled from within said collapsible liquid chamber and forced to said liquid outlet path upon contraction of said collapsible liquid chamber from said expanded volume to said contracted volume, wherein air is drawn into said collapsible air chamber upon expansion of said collapsible air chamber from said contracted volume to said expanded volume, and air within said collapsible air chamber is expelled from within said collapsible air chamber and forced to said air outlet path upon contraction of said collapsible air chamber from said expanded volume to said contracted volume, and wherein air forced through said air outlet path and liquid forced through said liquid outlet path create a mixture of air and liquid at said mixing chamber.
