A liquid spray gun nozzle assembly is disclosed comprising a coating liquid inlet portion comprising a liquid connector for connection to an external liquid source; a coating liquid outlet portion comprising a liquid nozzle for spraying a coating liquid fed into the nozzle assembly through the coating liquid inlet portion, the liquid nozzle being disposed along a spray axis; a coating liquid flow path fluidly connecting the coating liquid inlet portion to the liquid nozzle; and a spray gun connection portion opposite the coating liquid outlet portion adapted to connect the liquid spray gun nozzle assembly to a compatible liquid spray gun body. The spray gun connection portion comprises a nozzle assembly sealing surface adapted to seal the liquid spray gun nozzle assembly to the compatible liquid spray gun body, the nozzle assembly sealing surface comprising first and second sealing members that are each circular and concentric with one another.

An in-situ foam generation apparatus includes a dissolution chamber that houses a polymer stick cavity or canister, a mixing chamber that houses a static mixer, and a foaming chamber that houses a mechanical agitator in fluid communication with a compressed air inlet. The chambers are in fluid communication with one another by way of a respective chamber inlet and outlet, with the mixing chamber being located between the dissolution and foaming chambers. A pressure regulator can be used to control the incoming aqueous solution pressure to the dissolution chamber. A nozzle exhaust is in fluid communication with the outlet of the foaming chamber. One or more polymer sticks that include one or more cleaning agent can be loaded into the cavity or canister of the dissolution chamber. An end consistency of the polymer stick can be in a range of partially solidified to fully solidified.

The invention pertains generally to an improved fluid dispensing device, particularly a dispensing device which employs at least one hemispherical domed cannister source of reactants and which uses a color-changing dispensing plastic tip to inform the end-user if the reactants are at a proper use temperature.

A reservoir dispenser for a bidet washing apparatus includes a housing unit having a chamber, wherein the chamber is capable of holding a liquid wash solution; a lid with one or more openings therethrough, wherein the lid is attachable to the chamber; an activator having a proximal handle or a bar, a stem, and a distal stem bottom end piece, wherein activator is located through one of the one or more openings in the lid; and a connecting tube having a water inlet, a choke region, a suction tube, and a water outlet, wherein the connecting tube is permanently or reversibly attachable to the chamber.

A device for dispensing a fluid product, having a body with a dispensing orifice, two removable reservoirs each containing a single dose of fluid product, a dispensing mechanism, and an actuating mechanism. The reservoirs are closed before the dispensing device is actuated. The body has a mechanism for opening each reservoir and adapted to open the reservoirs during actuation of the device. The reservoirs each form a sealed unit which is separate from said body, each reservoir filled with a respective fluid product and hermetically sealed before installed in the body. The body has a receiving mechanism for lateral installation of the reservoirs in the body.

A spray head for atomising fluid ejected from a fluid conduit, the spray head comprising: a body having a longitudinal bore for receiving the fluid conduit such that a distal tip of the fluid conduit extends to a distal end of the longitudinal bore, the body being configured to direct a balanced flow of gaseous medium over the distal tip of the fluid conduit, when received within the longitudinal bore, so as to promote atomisation of the fluid as it is ejected from the distal tip of the fluid conduit, wherein the body comprises at least two radially separable segments, each of which defines part of the longitudinal bore, said at least two segments when combined forming said body having a longitudinal bore, whereby the fluid conduit is received within the longitudinal bore by locating said at least two segments around the fluid conduit.

Systems and methods for spraying a liquid treatment solution include a syringe attachment device and a handheld device. The syringe attachment device can be configured to secure a syringe containing the liquid treatment solution. The handheld device can have a movable slide configured to dispense the treatment solution from the syringe. The spray deposition system can include a cover' positioned to provide an impervious barrier between at least a portion of the syringe attachment device and the handheld device. The cover can be attached to the syringe attachment device prior to coupling the devices together. In an example, the cover can have a generally tubular shape with a closed end and an open end. The handheld device can be inserted into the cover and the cover can enclose the handheld device in the assembled position. In an example, the cover can be sterile and at least a portion of the syringe attachment device can be sterile.
