A system includes a conversion sleeve having a first mounting feature and a second mounting feature. The first mounting feature is configured to couple the conversion sleeve to a fluid connection of a first spray component. The second mounting feature is configured to couple the conversion sleeve to an adapter. The adapter is configured to be coupled to a second spray component.

An airbrush that sprays liquid in a mist form. A supply of a compressed air and a supply of the spray liquid can be controlled at the same time only using a spray button included in a spray head. Accordingly, a loss of the spray liquid can be minimized, the airbrush can be maintained clean, and usability of the airbrush can be enhanced.

Container assemblies (100) that transition between a sealing state and a retained venting state are described. The container assemblies each include a body portion (110) having an open end (113), and a lid portion (120) adapted to cover the open end of the body portion to create an enclosed volume, e.g. reservoir, and additionally comprise a venting feature (140). When the fluid pressure within the enclosed volume is less than a threshold pressure, the lid portion is in a sealing state such that the lid portion and the body portion cooperate to maintain a substantially fluid-tight seal against fluid leaving the enclosed volume. When the fluid pressure is greater than or equal to the threshold pressure, the lid portion is in a retained venting state such that the excess fluid pressure from the enclosed volume vents through the venting feature while retaining the lid portion on the body portion.

Presently described are components of a spray application system. At least one component comprises a liquid repellent surface layer. The liquid repellent surface (e.g. layer) may comprise a porous layer and a lubricant impregnated into pores of the porous layer; a fluoropolymer; a fluorochemical material and an organic polymeric binder; or a fluorochemical material melt additive and a thermoplastic polymeric material component. The component is typically a liquid reservoir, a liquid reservoir liner, a lid for a liquid reservoir or liner, or a combination thereof. In some embodiments, the component comprises a thermoplastic polymeric material. In some favored embodiments, the component is a removable liquid reservoir or liner. In some favored embodiments, the component is a collapsible liquid reservoir or liner. The spray application system typically further comprises a gravity-fed spray gun. Also described are spray application systems, methods of using a spray application system, as well as methods of making a component of a spray application system wherein the component has a liquid repellent surface.

The present disclosure involves apparatuses and methods for coating a lapping plate with an aqueous composition. The apparatus can be configured and the aqueous composition can be formulated so that the aqueous composition can flow to a spray nozzle device solely due to gravity in a batchwise manner.

The invention relates to a paint spray gun, comprising a tubular main body and a handle which is provided on the main body and has an actuatable trigger, wherein the main body has a spray opening on a first end face. The paint spray gun comprises a nozzle part arranged in the main body and a nozzle needle which can be moved in the nozzle part, wherein actuation of the trigger causes the nozzle needle to move in the nozzle part. The paint spray gun also comprises an air inlet opening and a fan which is driven by an electric motor for producing an air flow from the air inlet opening to the spray opening. The invention is characterised in that the electric motor and the fan are arranged in the main body and the air inlet opening is arranged on an end face of the main body opposite the first end face.

A connector system for a liquid container system for a spray gun includes a lid that includes a liquid outlet and an adapter. The adapter includes a spray gun end and a lid end. The ends are connected with a liquid-tight passageway. Further, the spray gun end is adapted for releasable engagement with a liquid inlet port of the spray gun and the lid end is adapted for releasable engagement with the liquid outlet. The connector system also includes a plurality of interlocking tab assemblies for releasably attaching the adapter to the lid. Each assembly includes a first tab and a second tab, wherein an end of the first tab is adapted to secure the adapter to the lid when the first tab and the second tab are interlocked.

A fluid reservoir for a spray gun, which fluid reservoir has a material outlet which is configured for the direct and/or indirect connection to a spray gun. The fluid reservoir includes a material container which is closed at least at one end face by a disk-shaped closing wall. A ventilation device is arranged on the outside of the closing wall. Advantageously, the closing wall is provided with a concavity which uniformly extends over the closing wall.

A spray gun fluid reservoir has a material outlet which is configured for the direct and/or indirect connection to a spray gun. The fluid reservoir includes a material container and a screw cap closing the material container. During a detachable and fluid-tight connection of the material container and the screw cap and the forming of a screw connection, an edge region of the material container is to be arranged in a receiving groove at the screw cap. Advantageously, a central region of the screw cap, which adjoins the receiving groove, is designed as a continuation of at least a predominant part of an inner limb of the receiving groove.

An adapter for communicating a fluid from a fluid reservoir can to a fluid applicator is disclosed. The adapter includes an inlet port, an outlet port, and a tapering central section. The inlet port includes an internally-threaded hollow cylindrical structure. The outlet port includes an externally-threaded hollow cylindrical structure coupled to and in fluid communication with the inlet port. An internal diameter of the inlet port is larger than an internal diameter of the outlet port. The tapering central section fluidly couples the internal diameter of the inlet port to the internal diameter of the outlet port and creates a fluid flow path there between. The inlet port is adapted to be fluidly coupled to an externally-threaded cap of the fluid reservoir can and the outlet port is adapted to be fluidly coupled to an internally-threaded fluid intake port of the fluid applicator.
