ABSTRACT:
A manually actuated pump sprayer has an unvalved vent port connected by a vent tube to a float buoyed on the liquid level within the container. A dip tube forming a liquid passage extends from a valve controlled inlet which leads into the pump chamber. A terminal end of the liquid passage defined by the dip tube is connected to the float for communicating that end with the liquid in the container, and a terminal end of the air passage defined by the vent tube is connected to the float for communicating the air passage terminal end with the head space in the container. The pressure within the head space is always maintained at atmospheric, and the sprayer is capable of being operated in any position without leakage. The tubes may formed as an integrally extruded double tube with air pockets formed along the length of the double tube to define the float. And, buoyant material forming the air passage may define the float.
