摘要:
A spray bottle has a ball swivel joint enabling angular orientation of the spray head with respect to the bottle. Both liquid and air are conducted between the pump and the bottle in separate passageways in the swivel joint, thus enabling use of a conventional pump. These passageways may be spaced apart or substantially concentric. A highly flexible pickup hose has a weight at its distal or pickup end, so that the distal and remains immersed in liquid, even when the spray bottle is inverted. In alternative embodiments, the pickup hose is bendable, rather than highly flexible. Tightening a cap adjusts tension on the swivel joint, thus varying pressure required to adjust spray head angularity or to immobilize the spray head at a desired angularity. The swivel joint may include one or more ball members.
