Claim:
A sprayer head assembly for dispensing a chemical; the sprayer head assembly comprising: a carrier fluid connection portion that is configured to be connected to a carrier fluid source, the carrier fluid connection portion forming a carrier fluid passage that is placed in communication with a carrier fluid source when the carrier fluid connection portion is coupled to the carrier fluid source, the carrier fluid passage generally extending in a first direction, the carrier fluid connection portion including a carrier fluid sealing portion; a chemical connection portion that forms a chemical passage, the chemical connection portion configured to be connected to a container to place the chemical passage in communication with a cavity in the container, and a body portion defining, at least in part, a first passage and a second passage, the first passage intersecting with the second passage, the body portion further including a second passage sealing portion; wherein the body portion is moveable with respect to the carrier fluid connection portion in a second direction generally parallel to the first direction, the body portion being moveable between at least a first position in which the second passage sealing portion acts to prevent carrier fluid from being in communication with the first passage through the second passage and a second position in which the second passage sealing portion acts to allow carrier fluid to be in communication with the first passage through the second passage, the second passage sealing portion being displaced along the second direction as the body portion is moved from the first position to the second position.
