ABSTRACT:
A hand-held gravity feed spray bottle. The liquid reservoir which supplies the spray mechanism is situated so that it is above the spray and pump mechanism when held by a user. The reservoir is affixed so that its longitudinal axis is at an angle to that of the spray mechanism. The pump mechanism is a standard hand pump with a plunger reciprocating in a chamber. The reservoir includes a liquid feed tube and a pressure equalization tube. One-way check valves in each of these tubes ensures that there is no leakage from the reservoir.
