An improved pressurizing sprayer removably attaches to the threaded neck of a container and includes a main body having a handle portion and a head portion. The handle includes a top portion with an exposed trigger and an inside portion in which a hand operated squeeze bulb pump is fitted. The head portion houses a pinch valve which is interconnected in-between a spray nozzle and a fluid conduit. Manually squeezing the pump delivers air into the container. Manually pressing the trigger continuously or intermittently opens the pinch valve allowing the fluid to flow through the conduit and out of the spray nozzle in the form of a pre selected spray pattern. Relatively few pump strokes are required to pressurize the sprayer. The tasks of aiming, spraying, and pressurizing can be completed simultaneously and with the use of only one hand.
