The invention provides a liquid spray gun connectable to a fluid reservoir through a fluid outlet. The spray gun comprises a socket geometry arranged for engagement with a co-operating connector for releasable connecting the spray gun with the fluid outlet. The socket geometry comprises a bore having an opening on one end, an end surface surrounding the bore's opening at least partially, and a lug portion spaced apart from the end surface in an axial direction parallel to a central axis of the bore. The lug portion has a lower surface being adapted to engage with the connector and to retain the connector in the axial direction. The end surface comprises a first keying geometry that is adapted to restrict rotation of the connector in at least one direction.

Liquid spray gun, connector ring, liquid spraying apparatus and adapter system

Fluid liners and container assemblies for a spraying apparatus and related methods of use are provided. The disclosed liners include a side wall defining a fluid-containing portion and an open end, a flange extending outwardly from the side wall, and a latching member coupled to the flange, where the latching member includes a retaining feature for releasably coupling the side wall to a lid compatible with the liner. Disclosed fluid containers include a lid having a fluid outlet adapted to couple the lid to the spraying apparatus and a collapsible liner, where either the liner or lid comprises a latch that releasably couples the liner and the lid to each other. Advantageously, the fluid liners and fluid containers can provide enhanced storage options for container contents between spraying operations.

Container for a spraying device

A spray gun cup lid is disclosed comprising a modular lid base and a modular liquid outlet that is formed independently of the modular lid base and is connected at an interface to the modular lid base. The modular liquid outlet comprises an outlet connection member to allow connection to a compatible spray gun.

Modular spray gun lid assemblies and methods of design and use

Securement for paint dispensing system

A spray gun and a detachable liquid reservoir releasably attached to the spray gun by engagement of mateable, non-threaded formations provided on the spray gun and the reservoir. The spray gun has an integral connector boss with a socket for reception of a connector tube of the reservoir. The boss has an external flange at the distal end and the reservoir has hook members separate from the connector tube. The hook members are co-operable with the flange when the connector tube is received in the socket to secure releasably the reservoir to the spray gun. In another arrangement, the connector tube is an interference friction-fit in the socket to secure releasably the reservoir to the spray gun. In yet another arrangement, the connector tube has bayonet lugs co-operable with bayonet grooves in the wall of the socket when the connector tube is received in the socket to secure releasably the reservoir to the spray gun. In a still further arrangement, the reservoir has an integral spout received in the socket integral with the spray gun and provided with a helical projection co-operable with the underside of a radial lug externally of the socket to secure the reservoir.

Spraygun with built-in quick-fit connector

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.

Spray gun and nozzle assembly attachment

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 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 a relative to the base plane. Also disclosed are improved lids for spray gun cups, and improved connections between the lid(s) and spray gun cup receptacles.

Spray gun cups, receptacles, lids, and methods of use

Container lid

The present invention relates to a fluid delivery assembly for a spraying apparatus. The assembly comprises an outer cup, a lid having a fluid outlet adapted to couple the lid to the spraying apparatus, and a liner for holding paint. The fluid delivery assembly comprises an interlocking keyed geometry adapted to prevent rotation of at least one of the lid and the liner with respect to the cup. The interlocking keyed geometry comprises at least one of (a) at least one protrusion of the cup extending into at least one recess of the lid, and (b) at least one protrusion of the lid extending into at least one recess of the cup, wherein the liner is trapped between the protrusion and the recess. The invention also relates to liners for such fluid delivery assemblies, which may be provided as a set of liners having different inners volumes.

Fluid delivery assembly for a spraying apparatus

Spray gun reservoir components are disclosed. The spray gun reservoir component includes a liquid outlet and an outer face, and defines a centerline plane and an attachment plane. The liquid outlet surrounds a longitudinal axis. The outer face extends away from the liquid outlet. The centerline plane passes through the longitudinal axis. The attachment plane is defined orthogonally to the longitudinal axis and the centerline plane. The outer face further comprises a retention feature extending away from the centerline plane and generally parallel to the attachment plane. In some embodiments, the spray gun reservoir component further comprises a bearing surface formed on the outer face along the attachment plane to engage with a corresponding bearing surface on a liquid spray gun attachment point, with the bearing surface comprising the retention feature.

Connector system for hand-held spray guns

Provided are devices for coating a contoured surface or a three-dimensional structure, and methods of making and using the same. The devices have geometries that are in point contact with the contoured surface. The geometries are substantially rigid and are provided by a flexible applicator. In this way, the flexible applicator permits conformance to the surface contours, along with rigid point contact that provides uniform and consistent coverage of liquid material. Specifically, the devices comprise a handle and an applicator pliantly affixed to the handle, the applicator comprising a plurality of spaced geometries. The devices meter film-forming coating liquids onto contoured surfaces or three-dimensional structures to form uniform coatings and resulting uniform films.

Devices for coating contoured surfaces

Container

A barrel for use with a liquid spray gun platform to provide a liquid spray gun comprises a main body and an inseparable nozzle. The main body comprises at least one center air delivery passage and at least one liquid-handling passage. The inseparable nozzle defines a liquid-emitting orifice that is in fluid communication with the at least on liquid-handling passage of the main body, and defines a center air orifice that is in fluid communication with the at least on center air delivery passage of the main body.
