An applicator (200), for applying a glutinous substance (140) to a seam (330) between a first part (310) and a second part (320), comprises a roller (210), comprising a circumferential surface (216), and a housing (220), comprising a delivery port (222), a scraper (232), and a shaper (234). The roller (210) is coupled to the housing (220) and is rotatable relative to the housing (220) about an axis (202). The circumferential surface (216) of the roller (210) is communicatively coupled with the delivery port (222). The intersection of the circumferential surface (216) and a virtual plane, passing through the axis (202), is a non-linear segment (217). The scraper (232) is geometrically complementary at least with the non-linear segment. The shaper (234) is communicatively coupled with the scraper (232).

A threaded adapter device couples a liquid compound applicator, such as a paint applicator, to a liquid compound container in a liquid-tight manner, where the liquid applicator and the liquid container cannot be directly joined because they have incompatible screw-on thread configurations, but the threaded adapter device provides threads compatible with the threads of both the liquid applicator and the liquid container, as well as providing a fluid channel from the liquid container to the liquid applicator.

A spray gun adapter establishes fluid communication between a fluid pump of a handheld airless spray gun and an applicator accessory. The adapter comprises an adapter body, a head attached to the adapter body, and a protrusion. The adapter body comprises an upper portion, a lower portion, a radial inlet located in a sidewall of the adapter body between the upper and lower portions, and an adapter bore having a first diameter in fluid communication with the radial inlet. The head attached to the adapter body is attached at the upper portion of the adapter body. The head comprises a cavity in fluid communication with the adapter bore and having a second diameter larger than the first diameter, an adapter outlet located in the upper portion of the adapter body and in fluid communication with the cavity, and a handle extending radially from the head. The protrusion extends radially from the adapter body between the upper portion and the lower portion of the adapter body.

The invention is a roller liquid compound applicator configured to attach to the threaded neck of a liquid supply container for the purpose of applying a coating of a liquid compound to a target surface, and includes: a U-shaped roller support frame including a substantially cylindrical dispenser coupling cap and a drip guard attached to the dispenser coupling cap, the dispenser coupling cap having a threaded cavity configured for mating with the threaded neck of the liquid supply container; and a liquid compound roller sleeve secured to the roller support frame.

An apparatus for applying a two-component liquid composition to a surface has a housing having an open end, an inner surface and an outer surface, an applicator retained in the housing and projecting through the open end, two containers removably mounted to the inner surface of the housing, each container having a dispensing nozzle extending through an aperture in the housing and arranged adjacent the applicator. There is a cutting device arranged on the housing adjacent the nozzles, the cutting device having at least one blade, wherein pressing the cutting device causes the blades to pierce the nozzles and allow contents of the containers to exit the containers and flow to the applicator.

A device for applying a mixed component includes first and second receptacles configured to receive first and second components, respectively, a static mixing nozzle, an applicator and an operating member. The static mixing nozzle includes a plurality of mixing elements, has a first end and a second end, and is in fluid communication with the first and second receptacles. The applicator includes a spray tip and an input for pressurized fluid, the spray tip is disposed downstream of the second end of the static mixing nozzle and is in fluid communication with the static mixing nozzle. The operating member is disposed on the applicator and is configured to control the pressurized fluid.

A device for applying a mixed component includes first and second component reservoirs, a static mixing nozzle configured to mix first and second components into the mixed component, a component passage disposed between the component reservoirs and the first end of the static mixing nozzle, the component passage disposed to enable the first and second components to flow from the reservoirs to the static mixing nozzle, a spray tip including an air inlet disposed at least partially between the first end of the spray tip and the second end of the spray tip, the first end of the spray tip being disposed adjacent the second end of the static mixing nozzle, a component applicator configured to use air to apply the mixed component through the second end of the spray tip, and a trigger mechanism disposed on the component applicator, and configured to enable application of the mixed component.
