Abstract: A spray gun reservoir has an oversize central opening 130 at one end allowing liquid to be added to the reservoir for fast filling with reduced risk of spillage. A cap member 132 is connectable to the reservoir and has a spout 115 providing a fluid outlet of reduced size relative to the opening 130 for connection to the spray gun. The reservoir can be disconnected from the cap member 132 when it is desired to add liquid to the reservoir. In this way, the reservoir can be re-filled in use.

Abstract: A liquid supply assembly for use with a spray gun (FIG. 1) comprises a reservoir 9 provided with a drop-in filter 10 for removing solid particles from liquid added to the reservoir 9. The reservoir 9 has a lid 12 with an outlet opening 12E connectable via a spout 16 to the spray gun and a separate inlet opening 12D in which a support collar 27 of the filter 10 is located. The filter 10 comprises a tubular mesh body 10A having an open end and a closed end. The open end is connected to the support collar 27 and the mesh body 10A extends away from the inlet opening 12D within the reservoir 9. The mesh body 10A is sized to pass through the filler opening 12D and has a high flow capacity to permit rapid filling of the reservoir 9. The filter 10 may be left in place when the reservoir 9 is connected to the spray gun and the reservoir 9 may be discarded together with the filter 10 after use.

Abstract: A system and method for preparing samples to test an environmental surface for an analyte of interest. The system can include a deformable self-supporting receptacle comprising a reservoir, and a loaded substrate positioned in the reservoir of the deformable self-supporting receptacle. The loaded substrate can include a substrate and a source collected from the surface. The method can include combining the loaded substrate and a diluent in the reservoir, and agitating the loaded substrate and the diluent to form a liquid composition comprising the source and the diluent.

Abstract: A paint reservoir has a fluid outlet 115 connectable to a spray gun 101 and a fluid inlet 131 provided with a removable screw cap 132 whereby the fluid inlet 131 is directly accessible for introducing paint to the reservoir while attached to the spray gun 101. The fluid outlet 115 and fluid inlet 131 may both be provided in an end wall of the reservoir with outlet 115 located on the longitudinal axis of the reservoir or offset to allow the size of the fluid inlet 131 to be increased for easier filling of the reservoir. The outlet 115 can be aligned with the longitudinal axis of the reservoir or it can be inclined relative to the longitudinal axis to provide greater clearance for access to the fluid inlet 131 when the reservoir is attached to the spray gun 101. In an alternative arrangement, the fluid outlet is provided in an end wall of the reservoir and the fluid inlet is provided in a sidewall of the reservoir.

Abstract: A spray gun (1) has a fluid reservoir (11) which contains a removable liner (13). The liner (13), which may be thermo/vacuum-formed from a plastic material, is a close fit within the interior of the reservoir and collapses as fluid is withdrawn from within the liner during operation of the gun. Preferably, the liner has a comparatively-rigid base and is capable of standing, unsupported, outside the reservoir. The side walls of the liner are preferably thin in comparison to the base and can be collapsed for disposal of the liner. The reservoir (11) has a removable lid (15) and is capable of standing, inverted, on its own so that it can be filled with fluid. The lid (15) also functions to secure the liner (13) in the reservoir and, at the end of a spraying operation, the lid (15) and the liner (13) are removed together from the reservoir (11) and discarded, thereby simplifying the cleaning of the spray gun.

The liner (13), which may be thermo/vacuum-formed from a planar material, has a shape that corresponds to and is a close fit within the interior of the container (12) and collapses as fluid is withdrawn from within the liner (13) during operation of the spray gun (1). The lid (15) has an outlet (16) connected to an inlet on the spray gun (1) for transfer of liquid from the reservoir (11) to the spray gun (1) and the container (12) has a vent (12A) in the base end for admitting air between the container (12) and the liner (13) as liquid is withdrawn from within the liner (13).

Abstract: A reservoir (402) for connection to a spray gun has a lid (410) provided with an outlet spout (415) that is rotatably received in a socket of an inlet adaptor (419) connectable to the spray gun. The lid (410) has a spring leg (425) spaced from the outlet spout (415) with a projection (426) at the distal end for self-latching engagement with a flange (423) of the adaptor (419) to secure releasably the reservoir (402) to the spray gun. The engagement of the projection (426) and flange (423) enables the reservoir (401) to be rotated through 360° to adjust the position of the reservoir (402) while attached to the spray gun.

Abstract: 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.

Abstract: A reservoir for use with a spray gun has a body and a flexible diaphragm that define a chamber for liquid to be supplied to the spray gun. The body has an outlet opening leading to a spout connectable to the spray gun and the diaphragm deflects to reduce the volume of the chamber as liquid is withdrawn from the reservoir. The diaphragm gradually conforms to the internal surface of the body as the liquid is withdrawn to prevent pockets forming in which the liquid may be trapped so that substantially all the liquid can be dispensed. The reservoir may be supplied pre-filled with the liquid.

The spray head 150 is releasably secured and can be detached from the spray gun body 102 and thrown away after use. The reservoir 156 is mounted on the spray head 150 and can be removed and thrown away with the spray head 150 after use.
