Infectious diseases may be acquired in public areas such as transportation terminals, shopping centers, schools, hospitals, restaurants and hotels. Large surface areas may be disinfected using a spray system to distribute a suitable fluid such as a disinfectant. Many existing spray systems are large and unwieldy causing operator fatigue. Some spray systems have large, heavy external tanks that provide fluid to the spray system using an external fluid hose. Disclosed is an improved portable spraying system that may be carried by a system operator. The improved system has a tank, a pump, a valve, a nozzle, and a fan all powered by a battery. The tank, the pump, and the battery are arranged to minimize operator fatigue. With the valve set to the priming position, fluid recirculates to prime the pump. Once the pump is primed, the valve is turned to the spray position to begin spraying.

A spraying assembly is provided. The spraying assembly includes at least one nozzle for liquid that is to be sprayed, and at least one active substance injector which is situated directly upstream from the at least one nozzle and to which liquid to be sprayed is supplied by a pump or a pressurized reservoir, with interposition of an obturator on a conduit connecting the pump or the pressurized reservoir to the injector. The spraying assembly also includes an outlet valve for each injector designed to close each outlet orifice. The present invention avoids overdosing or underdosing of the product that is to be sprayed as active substance.

A makeup machine includes a spray head, a main body, an arched track, and vertical support. The spray head has a receptacle to receive a spray cartridge containing a skin spray. The main body houses a controller circuit that controls a position of the spray head with respect to a target of the skin spray. The arched track has a curved shape on a horizontal plane, and the vertical support is attached to the arched track. The controller circuit causes the spray head to slide along the arched track, and adjusts a height of the vertical support to cause the arched track and the spray head to move up and down. The makeup machine also includes a linear track controlled by the controller circuit to adjust a horizontal distance between the spray head and the target.

A dispensing pump mechanism is provided. The pump comprises integrally molded temper-evidence part between a container collar and a spout; said collar has multiple off-centre outlet channel for dispensing one or more products from the container; said collar also comprises an integrated air vent to be blocked and opened by the rotation of the spout. The whole pump can be over-molded one-piece structure with elastic parts as being actuating parts. The pump improves the functions of the pump, such as lower restitution rate, less structural parts, lower cost, water/dust proof, lightweight, easy assembly.

A liquid object detector (160) includes a liquid object dispensing part (500), a sensor (161, 162, 163) configured to detect a liquid object dispensed by the liquid object dispensing part, and a sensor moving part (130, 165) configured to move the sensor in a direction crossing a dispensing direction of the liquid object.

A fluid dispensing gun for 1K-polyurethane foam includes a dispensing tube with a dosing nozzle at its outlet, a spring-loaded needle co-axially moveable in the dispensing tube for opening and closing the dosing nozzle, a trigger actuating the needle to open the nozzle and to dispense the fluid, a regulator regulating the degree of opening of the nozzle outlet and a coupler coupling a pressurized can to the gun. It also concerns a method for dispensing 1K-polyurethane foam. The fluid dispensing gun includes a delivery device delivering a curing fluid essentially parallel to the nozzle outlet that includes a curing fluid reservoir, a curing fluid outlet situated near the nozzle and a curing fluid line connecting the curing fluid reservoir and the curing fluid outlet, the trigger activating the delivery device. The curing fluid delivered in the same direction as the 1K-polyurethane foam and separately therefrom makes the foam cure more rapidly.

A dispensing pump mechanism is provided. The pump comprises integrally molded temper-evidence part between a container collar and a spout; said collar has multiple off-centre outlet channel for dispensing one or more products from the container; said collar also comprises an integrated air vent to be blocked and opened by the rotation of the spout. The whole pump can be over-molded one-piece structure with elastic parts as being actuating parts. The pump improves the functions of the pump, such as lower restitution rate, less structural parts, lower cost, water/dust proof, lightweight, easy assembly.

A liquid object detector (160) includes a liquid object dispensing part (500), a sensor (161, 162, 163) configured to detect a liquid object dispensed by the liquid object dispensing part, and a sensor moving part (130, 165) configured to move the sensor in a direction crossing a dispensing direction of the liquid object.

Tunable thermoplastic polymer powder feedstock formulations and tunable conductive thermoplastic polymer powder feedstock formulations are disclosed for delivery to a high-velocity sprayer are presently disclosed, along with tunable coatings made from the disclosed formulations, and methods for delivering such tunable thermoplastic polymer coatings to substrates.

Dispenser systems including a plurality of containers and an applicator. The plurality of containers are supported together to define a container set. Each container in the plurality of containers includes a dispenser configured to dispense contents within the container. The applicator is operatively coupled to the container set and configured to apply contents from the containers to a target surface. In some examples, the dispenser system includes a cap. In certain examples, the dispenser system includes a cleaning system.
