ABSTRACT:
The spraying device of the present invention includes a container having a hollow interior, a threaded open top, and a closed bottom. The enclosed bottom includes an orifice that is adapted to receive a pressurized fluid line. A flexible bladder is inserted through the open top into the container. A cap is adapted to be removably secured to the open top of the container. Extending through the cap is a through hole which receives a conduit that extends from the interior of the bladder to the exterior of the container. A spraying mechanism is attached to the exterior end of the conduit. Utilization of the device occurs when fluid from the pressurized fluid line enters the interior of the container exerts pressure on the bladder to cause the bladder to contract and force the fluid located inside to escape via the conduit and spraying mechanism.
