Disclosed is an integrated spray machine which comprises a shell, a sprayer assembly, an air pump motor assembly, a battery, a circuit board and a switch, wherein the sprayer assembly comprises a housing, a container and a spray mechanism; the housing is matched with the shell, the container and the spray mechanism are mounted in the housing correspondingly, and the container communicates with a liquid inlet of the spray mechanism; the air pump motor assembly, the battery and the circuit board are all arranged in the shell, the switch is arranged on the wall of the shell, the air pump motor assembly, the battery and the switch are all electrically connected with the circuit board, and an air outlet of the air pump motor assembly communicates with an air inlet of the spray mechanism through an air pipe.

A battery-operated dispenser includes a shell with a moveable slider for extending a barrel of the dispenser to allow targeted application of a fluid or product from a container to which the dispenser is attached.

An apparatus for accurately coating discrete patches of coating on a moving substrate is described. The coating system applies coating to a moving substrate using a coating distribution device. A flow pump pumps the coating from a reservoir into the coating distributing device where a portion of the coating is deposited and the remainder is allowed to returned back to the reservoir. The coating distribution device selectively meters a portion of the coating it receives from the flow pump onto the substrate at a variable rate. When the coating distribution device transitions from metering to not metering and to reverse metering, it induces a vacuum in the coating distribution device. The induced vacuum causes a portion of the coating being distributed onto the substrate to flow in reverse quickly breaking the deposition of the coating.

A spray gun cup receptacle is disclosed comprising an open end for receiving a liner within a cavity and a base end opposite the open end. The sidewall comprises at least one aperture through which the cavity is visible from outside the spray gun cup receptacle. The apertures are divided one above the other by a brace member, at least a portion of which is disposed at a brace member angle relative to the base plane. Also disclosed are receptacles comprising one or more tactile feedback members positioned adjacent an aperture.

An electrically powered, portable fluid dispenser that includes a main housing and extendable wand that when used in conjunction with an electric motor, a self-feeding tentacle pumping spinning element, tentacle feed tube, and focusable vibrating backstops, is able to pump, atomize, and dispense, low and high viscosity fluid with controlled directionality and droplet size.

A spray gun cup receptacle is disclosed comprising an open end for receiving a liner within a cavity and a base end opposite the open end. The base end is positionable with respect to a work surface with the open end facing upwards such that a base plane passing through the base end is parallel to the work surface. A sidewall surrounds the cavity and connects the open end to the base end. The sidewall comprises two apertures through which the cavity is visible from outside the spray gun cup receptacle. The two apertures are divided one above the other by a brace member, at least a portion of which is disposed at a brace member angle relative to the base plane.

A dispenser or applicator of garden liquids such as herbicides and pesticides. It is a long tube, preferably translucent, that has an applicator tip assembly at the base that dispenses a quantity of the liquid to one plant at a time in an exact spot while the user remains standing comfortably (without having to bend or stoop over). The device also has a spray nozzle so that a larger area can be sprayed, if desired. Finally, it has a top cap that has a small opening in it that allows a user to invert the device and apply the liquid to a larger area by simply moving the device around and sprinkling the liquid where desired. Because the tube is long, the user can remain standing comfortable and the liquid is dispensed at ground level. The device also comes with a small mounting bracket for securing it on a wall.
