Definitions
- the present disclosure relates in general to liquid spray systems and methods of using liquid spray systems, particularly, although not exclusively for spraying paint.
- a surface to be painted is painted by hand using a brush, pad or roller (conventional applicators).
- painting by brush in particular, can be accurate, the application of paint onto a surface in this manner is slow.
- the use of a pad or roller helps to speed-up the painting process compared to the use of a brush (albeit at the cost of some accuracy).
- all of the aforementioned approaches require paint to be frequently absorbed onto the specific conventional applicator before the paint can be transferred to the surface to be painted.
- Another conventional paint application approach is to spray the paint toward a surface. Spraying is more efficient than direct contact of the applicator to the surface because the sprayed paint is typically applied in a continuous or semi-continuous manner from a reservoir. Furthermore, the coverage of paint onto a surface is generally more consistent than a brush, pad or roller application and possible accumulation of paint (i.e. unwanted lumps) are avoided.
- the spraying technique relies on the adhesion properties of the paint to the surface, some spray systems lead to splashback (also known as bounce back) of the paint. This is because not all of the sprayed paint is capable of adhering to the surface and is consequently repelled away from the surface.

- kit of parts for a liquid spray system comprising:
- the liquid spray system comprises a receptacle for holding liquid.
- the receptacle is suitably a container for storing liquid.
- the receptacle includes a main body and a displacement member movable within the main body.
- the displacement member is therefore suitably a moveable member.
- the main body is suitably an outer part of the receptacle and encloses the displacement member.
- the receptacle comprises a reservoir having a reservoir outlet, suitably adapted to allow release of the liquid from the reservoir.
- the displacement member is suitably configured to move relative to the main body in order to vary the capacity of the reservoir.
- the displacement member comprises a liquid contacting side and an air contacting side.
- the liquid contacting side and the air contacting side may be permanent in that, when liquid is present in the receptacle, the liquid is always present on the liquid contacting side.
- the receptacle further comprises an air inlet.
- the air inlet is communicable with the air contacting side of the displacement member. That is, the air inlet is in fluid communication with air contacting side of the displacement member.
- the spray system further comprises a support structure for supporting the receptacle. That is, the support structure suitably restricts movement of the receptacle relative to the support structure. Therefore, when the receptacle is coupled to the support structure, the receptacle and support structure are suitably provided as one body.
- the spray system comprises a spray applicator.
- the spray applicator is suitably configured to release liquid from the spray system in the form of spray.
- the spray applicator comprises a liquid inlet for receiving liquid from the liquid outlet of the reservoir, a liquid outlet, a liquid outlet valve for controlling the release of liquid via the liquid outlet and a trigger for controlling the outlet valve. That is, the outlet valve is suitably a trigger-operated valve, wherein activation of the trigger (which may comprise movement) may produce movement in the outlet valve.
- the spray system further comprises an air pressurising device.
- the air pressurising device is in fluid communication with the air contacting side of the displacement member and is arranged to be operable to move the displacement member, in use.
- the air pressurising device is also arranged to be in fluid communication with the liquid outlet valve of the spray applicator and is arranged to be operable to propel liquid out of the liquid outlet valve of the spray applicator, in use.
- the air pressuring device may be operable to provide a driving force to move the displacement member so that liquid is expelled from the reservoir and out of the spray applicator.
- the air from the air pressurizing device suitably atomises the liquid.
- the receptacle is provided as a cartridge.
- the receptacle is easy to install and the risk of liquid loss is reduced.
- the cartridge may be a refillable cartridge rather than a one-time use cartridge. Refilling the cartridge may only be possible by allowing air to be released from inside the receptacle to allow the displacement member to move.
- the receptacle or cartridge may comprise a tamper-proofing means such as a tamperproof seal.
- the cartridge may comprise a one-way valve for restricting liquid flow into the cartridge.
- the air inlet of the receptacle may be the one-way valve.
- the one-way valve may be overridden to release air from the air contacting side of the displacement member.
- the receptacle may comprise a pressure relief valve for equalising pressure on the air side of the displacement member with ambient air. That is, the effect of a one-way valve may be overcome by the pressure relief valve.
- the spray system may comprise a plurality of receptacles.
- the spray system may comprise a single receptacle that is in use at any one time and space for accommodating another receptacle that is not in use (i.e. liquid is not transportable to the spray applicator).
- the reservoir of each receptacle may have a different volumetric capacity.
- a plurality of receptacles may be in fluid communication with the spray applicator or only one receptacle at any one time may be in fluid communication with the spray applicator.
- An inner wall of the main body that is configured to contact air rather than liquid may comprise a non-stick coating to allow the displacement member to contact the inner wall without sticking thereto.
- the non-stick coating may be a sprayable non-stick coating.
- the term non-stick refers to a reduction in tackiness such that abutting parts are prevented from being bonded to each other.
- the non-stick coating applied to the inner wall may have the effect of reducing the adherence of the displacement member to the main body such that the displacement member can move freely.
- the displacement member comprises a flexible membrane
- the main body may comprise a coating arranged on an air contacting side for preventing adhesion of the flexible membrane with the main body. The coating is therefore suitably a non-stick coating.
- the main body may be cylindrical.
- the main body may comprise a neck within which the liquid outlet of the reservoir is arranged.
- the main body may be a pressure vessel to allow the reservoir to be under pressure. That is, the main body may resist deformation under liquid and/or air pressure.
- the main body may define part of the reservoir.
- the portion of the main body forming part of the reservoir may be variable depending on the varying capacity of the reservoir.
- the displacement member alone may define the reservoir such that when the reservoir contains liquid the liquid is not configured to come into contact with the main body.
- the reservoir outlet may also function as an inlet but may only be operable when air is releasable from the air contacting side because air between the displacement member and the main body may prevent the reservoir from filling and/or refilling.
- the displacement member may be slidably arranged relative to the main body. That is, the movement of the displacement member is suitably a sliding movement.
- the displacement member may be generally rigid or generally flexible.
- the displacement member may comprise a flexible membrane that is operable as a bladder.
- the bladder may contract and expand. Expansion of the bladder may cause a reversible thinning of the membrane.
- the main body may determine a limit of expansion of the bladder, particularly an inner wall of the main body.
- the flexible membrane may be coupled to the main body of the receptacle at a portion of the air inlet and a portion of the liquid outlet. This ensures that the flexible membrane is held relative to the main body.
- the liquid outlet portion of the reservoir and air inlet portion of the receptacle are arranged at or towards opposite ends of the receptacle.
- the liquid outlet portion may be arranged in a neck of the main body.
- the support structure comprises an accommodating part for receiving the receptacle.

- the support structure is capable of holding cartridges of varying capacity and/or size.
- the receptacle 1a shown in Figure 1 is installed in a support structure 200a.
- the support structure is a floor-standing support structure. That is, the support structure has a predetermined resting position. The resting position equates to a vertical orientation of the receptacle when installed in the support structure.
- the spray system 1a further comprises a spray applicator 300 that is holdable by the hand of the user.
- the spray applicator comprises a trigger 340 for activating the release of the liquid away from a liquid outlet valve (not shown) of the spray applicator.
- the trigger is preferably biased towards a first position that is a non-activating position.
- the biasing means may be a resilient member such as a spring.
- the spray applicator is a spray gun.
- the spray applicator has a liquid outlet 320 that is arranged at an opposite end to a liquid inlet 310.
- the spray system 1a comprises an air pressurising device 400a in the form of a compressor.
- the compressor supplies the receptacle 100 with air pressure so that the liquid can be driven out of the receptacle and towards the spray applicator 300.
- the compressor is shown to be powered by mains electricity and comprises an electrical connector 404 that supplies electricity through an electrical cable 402.
- the air pressurising device may be a canister of pressurised air.
- the canister is advantageous because it is portable and can be easily used outside without the risk of electrical shock.
- the compressor may be powered by a battery rather than mains electricity.
- the spray system 1a is further shown with transmissions lines 410, 420a, 520a.
- the transmission lines are hoses that convey air or liquid around the spray system.
- a first air transmission line 410 provides fluid communication between the compressor and the receptacle 100.
- a second air transmission line 420a and a first liquid transmission line 520a fluidly link the receptacle and the spray applicator 300.
- a three-way connector may separate the first and second air transmission lines so that air supplied under pressure from the compressor is diverted from the first air transmission line towards the receptacle to drive a displacement member 130 of the receptacle and force liquid out of the receptacle.
- control unit 600a with control dials 610a is shown that is attached to the support structure 200a. Although three control dials are shown, at least one control dial may be used to simplify the options for adjustment.
- the control unit is removable from the support structure. That is, the control unit can be coupled and decoupled to the support structure. This allows the control unit to be removed for maintenance, repair or update.
- the receptacle 100 is shown in cross-section in Figure 2 .
- the receptacle comprises a main body 110 that is an outer part of the receptacle.
- the main body may be made from metal.

- the reservoir is provided by the displacement member alone and not the main body.
- the reservoir 120 may be formed by the main body and the displacement member, for example, if the displacement member is provided as a piston.
- the displacement member therefore has an air contacting side 134 and a liquid contacting side 132.
- the main body also has an air contacting side 112 that comes into contact with the displacement member.
- the air contacting side comprises a coating that is a non-stick coating to avoid the adhesion of the displacement member to the main body.
- Figure 2 further shows an air inlet 140.
- the air inlet allows air to enter the receptacle 100 from the compressor.
- the air contacts the air contacting side 112 of the main body 110 and the air contacting side 134 of the displacement member 130 to force the displacement to move.
- the displacement member is a bladder and comprises a flexible membrane allowing the displacement member to be manipulated so that the displacement member can expand and contract by air pressure.
- the air inlet comprises a one-way valve 142 for restricting air flow and preventing air flow out of the receptacle. This prevents the reservoir 120 being filled without circumventing (i.e. overcoming) the one-way valve because the displacement member is prevented from expanding when liquid enters the reservoir.
- the cartridge may not be refillable by the user without a special tool to open the one-way valve.
- the support structure 200a of the first embodiment is shown in more detail in Figures 3 to 5 .
- the support structure is shown with a removable control unit 600a that regulates the flow of air and/or liquid of the spray system 1a. Transmissions lines 420a, 520a are shown to transport the air and liquid around the system.

- a first liquid transmission line 510b is connected between a liquid outlet portion of the reservoir 120 and a connecting member 210 shown in Figure 7 .
- a second liquid transmission line 520b is configured to transmit liquid away from the connecting member and toward the liquid inlet 310 of the spray applicator 300.
- a second air transmission line 420b is configured to transmit air from the connecting member and toward the spray applicator to propel liquid out of the liquid outlet valve of the spray applicator.
- Both the second liquid transmission line and the second air transmission line comprise a pair of transmission sub-lines.
- a first air transmission sub-line 420b-1 is connected upstream of the control unit 600b and a second air transmission sub-line 420b-2 is connected downstream of the control unit.

- the support structure 200b comprises a telescopic handle for ease of storage.
- the support structure comprises a receptacle holding part 220 (i.e. an accommodating part) and a ground contacting part 230b.
- the support structure of the second embodiment is capable of holding a plurality of receptacles 100 at once.
- Each receptacle may be a different size as shown in Figure 7 .
- the receptacle holding part comprises a door that allows access to the inside of the receptacle holding part (i.e. the region accommodating the at least one receptacle).
- the door does not comprise a window.
- the ground contacting part comprises a plurality of wheels. The wheels may be connected by a common axle.
- the wheels may rotate independently and therefore have separate axles.
- the ground contacting part further comprises a foot provided away from the wheels. The foot does not move relative to the receptacle holding part but is configured to rest against a ground surface when the support structure is in a standing position.
- a spray system 1c according to a third embodiment is shown in Figure 9 .

- the support structure is worn by the user using shoulder straps 260c and the control unit is worn using a belt 270c.
- the air pressurising device 400a of the first embodiment is shown.
- the air pressurising device 400b of the second embodiment can equally be used.
- the air pressurising device is powered by mains electricity and comprises an electrical connector 404 that supplies electricity through an electrical cable 402.
- the first air transmission line 410 of the third embodiment is connected between the air pressurising device 400a and the control unit 600c.
- the control unit therefore acts as a hub about which the network of transmission lines is arranged.
- a second air transmission line 420c comprises a first air transmission sub-line 420c-1 which transmits air towards the receptacle 100 and a second air transmission sub-line 420c-2 transmits air towards the spray applicator 300.
- a first liquid transmission line 520c comprises a first liquid transmission sub-line 520c-1 which transmits liquid rom the receptacle 100 to the control unit and a second liquid transmission sub-line 520c-2 transmits liquid from the control unit to the spray applicator. Therefore, the first and second liquid transmission sub-lines flow in and out of the control unit whereas the first and second air transmission sub-lines both flow out of the control unit since the first air transmission line supplies the control unit with air from the air pressurising device.
- a spray system 1d according to a fourth embodiment is shown in Figure 10 .
- the spray system of the fourth embodiment is similar to the spray system 1c of the third embodiment in that the support structure 200d and control unit 600d (including at least one control dial 610d as shown in Figure 13 ) are both wearable on a user.

- the support structure comprises a plurality of compartments, each for the receptacle and the air pressurising device with battery. A lower compartment is the ground contacting part 230d.
- Figure 12 shows two variations of the shoulder straps 260e, 260f and belt 270e, 270f combination of Figures 9 and 10 . These variations comprise holders for further receptacles 100 or generally pockets for storing other items of use.
- the shoulder straps and belt are comfortable and convenient for a user.
- Figure 14 shows a method 1000 of using a liquid spray system.
- the method includes filling the receptacle with liquid (S100), preferably a coating composition such as a paint or varnish.
- the filling step may be performed using a one-way valve so that an end-user cannot easily re-fill the receptacle because the one-way valve may require a special tool to overcome.
- the receptacle can be loaded into a support structure (S200).
- the receptacle comprises a tamper-proofing means
- the step of loading the receptacle may disturb the tamper-proofing means and allow the liquid to be released from the receptacle.
- gas is supplied to a displacement member of the receptacle from a gas pressurising device (S300).
- the gas pressurising device may be a compressor and the gas may be air.
- the supply of gas under pressure results in the movement of the displacement member relative to a main body of the receptacle (S400).
- the displacement member therefore acts as a bladder and expands and contracts under pressure.
- a trigger on the spray applicator is activated (S600), preferably by hand.
- the liquid is then propelled from an outlet valve of the spray applicator using gas from the gas pressurising device as a propellant (S700).
