A system and method for dermal spraying includes a portable, hand-held dermal application device with one or more disposable cartridges that spray a dermal formulation onto the skin, the disposable cartridge having a nozzle that can be activated by placing the cartridge into the spray device.

The present invention relates to a shower head which comprises a dispenser for optionally or selectively dispensing a fluid additive such as soap, simultaneously or separately with the water. The invention discloses an innovative mechanism using optimized fluid mechanics for spraying water or cleansing solution for a more hygienic and overall cleansing experience.

A mix on exit sprayer having a water tank and a body the includes a chemical cartridge receiving cavity. A pump move water from the tank to a mixing chamber and a piston drives chemical concentrate from the cartridge into the mixing chamber. A venturi style mixing element mixes the water and concentrate and the pump moves the mixed fluid from the mixing chamber to a spray wand from which it can be expelled.

A foam sprayer includes a body defining a channel, a nozzle, and an adapter configured to releasably attach to a first fluid source that provides a first fluid at a first pressure. The foam sprayer includes a connector attached to the body and configured to releasably connect the body to the adapter or to a second fluid source that provides a second fluid at a second pressure that is substantially greater than the first pressure. The foam sprayer also includes a mode selection device configured to switch the foam sprayer between a low-pressure mode and a high-pressure mode. The foam sprayer is configured to generate foam from the first fluid when the foam sprayer is in the high-pressure mode. The foam sprayer is configured to generate foam from the second fluid when the foam sprayer is in the high-pressure mode.

A spray device includes a converging assembly, a container and a suction pipe. The converging assembly includes a first liquid channel, a second liquid channel, a first air channel and a second air channel. The first liquid channel and the first air channel communicate with an inlet of the second liquid channel. The second air channel communicates with the container. An end of the suction pipe communicates with the inlet of the second liquid channel, and another end is submerged in a solution in the container. When a liquid flows from the first liquid channel to the second liquid channel, air in the first liquid channel is discharged via the first air channel, the solution is sucked to the second liquid channel through the suction pipe, the solution and the liquid are mixed at the inlet of the second liquid channel, and then are sprayed from the second liquid channel.

A dispensing system including a hose-end-sprayer having a sprayer body assembled with a selected valve having a lever to selectively operate the hose-end-sprayer and a shipping clip capable of retaining the valve in a closed position during shipping; methods for manufacturing and assembling the same using a single sprayer body with multiple valve configurations.

A system and method for dermal spraying includes a portable, hand-held dermal application device with one or more disposable cartridges that spray a dermal formulation onto the skin, the disposable cartridge having a nozzle that can be activated by placing the cartridge into the spray device.

A shower head liquid agent dispenser includes a storage tank having a hollow interior space for storing a liquid agent, a first tubular member that is connected to the bottom end of the storage tank, a valve which can be manipulated between an on and off position, a second tubular member that is connected to a tee fitting which is selectively connected to a building's shower arm and a shower head assembly.

The present invention refers to a device for the discharge of a pressurised liquid comprising: a liquid intake section (2400), a liquid discharge lance (2300), a pump (2200), which can be connected to a motor (2100), the pump having an inlet connected to the intake section and an outlet connected to the discharge lance, where the discharge lance and the pump are connected by a connection (2800, 2801, 2802, 2803, 2804), with at most three rotational degrees of freedom and/or one translational degree of freedom.

A barrel (20) adapted for use with a spray gun (2) is disclosed. The barrel (20) comprises a boost feed port (44) fluidly connected to a boost passageway (48), the boost passageway (48) being integral to the barrel (20). The boost passageway (48) is adapted to convey a pressurized boost fluid originating in the spray gun (2) to a boost delivery port (56) to assist in urging a coating fluid from a compatible coating fluid reservoir (80) for spraying by the spray gun (2).
