Definitions
- Spray guns are widely used to apply a liquid to a substrate in a variety of industries.
- the liquid is contained in a reservoir attached to the gun from where it is fed to a spray nozzle.
- the liquid On emerging from the spray nozzle, the liquid is atomised and forms a spray with compressed air supplied to the nozzle.
- the liquid may be gravity fed or suction fed or, more recently, pressure fed by an air bleed from the compressed air line to the reservoir or even from the spray gun itself.
- the present invention is intended to improve further our existing system and provide additional benefits and advantages for the user.
- the paint pot 106 includes an outer container 108, a disposable liner 109, a disposable lid 110 and a collar 111 that are assembled in similar manner to the previous embodiment.
- the lid 110 has a central opening 130 bounded by an external tubular spigot 131 and a separate cap member 132 is provided for connecting the pot 106 to a spray gun (not shown). By locating the opening 130 centrally, the size of the opening 130 can be maximised for a given available space.
- the cap member 132 comprises a base 133 having a socket 134 with an internal screw thread 135 engageable with a complementary external screw thread 136 on the spigot 131 to secure releasably the cap member 132 to the lid 110 in a fluid-tight manner. It will be understood that additional sealing means may be provided to prevent leakage if required. For example the outer end of the spigot 131 may engage an O-ring (not shown) located within the cap member 132.
- the internal diameter of the spout 115 is considerably smaller than the diameter of the central opening 130 in the lid 110 of the reservoir.
- the spout 115 has an internal diameter of 10-15mm (approximately 1 ⁇ 2") and the central opening 130 has an internal diameter of 53mm (approximately 2").
- the spout 115 is coaxial with the central opening 130 so that, when connected to the spray gun, the reservoir is aligned with the central longitudinal axis of the spray gun. As a result, the weight of the reservoir and the liquid therein is evenly distributed so that balance, handling of the spray gun is not adversely affected.
- the opening 130 is oversize relative to the required flow when the reservoir is connected to the spray gun and permits fast-filling of the reservoir with liquid added through the opening 130 when the pot 106 is disconnected from the cap member 132.
- the pot 106 can be detached from the cap member 132 by unscrewing the connection between the spigot 131 and the cap member 132 to provide access to the opening 130. Liquid can then be added to the reservoir through the opening 130 and the pot 106 re-connected to the cap member 132 on the spray gun 101.
- the central opening 130 may be used to add liquid to the reservoir either when topping up the reservoir in use or when first filling the reservoir prior to commencing spraying.
- the opening 130 may also allow insertion of a tool to stir the contents of the reservoir allowing mixing to be carried out in the reservoir after the pot 106 has been assembled to secure the lid 110 to the liner 109. In this way, the risk of spillage is further reduced.
- a removable filter may be located in the central opening 130 when adding liquid to the reservoir.
- the filter may be of any type and preferably has a large surface area so that the addition of liquid to the reservoir is not significantly reduced. In this way, provision of a filter in the cap member 132 may be dispensed with thereby reducing the risk of interruption or reduction in the flow of liquid to the spray gun due to blockage of the filter in use.
- FIG. 13 there is shown a second embodiment of the present invention in which like reference numerals in the series 200 are used to indicate parts corresponding to the previous embodiments and the construction and operation of similar parts will be readily understood from the description already given and will not be further described in detail.
- the liner 209 and lid 210 are permanently joined together.
- the liner 209 and lid 210 may be formed integrally in one piece by blow moulding.
- the liner 209 and lid 210 may be formed separately by moulding and connected together by welding, adhesive or other suitable means of forming a permanent join therebetween.
- the reservoir formed by permanently joining the liner 209 and lid 210 may be used without the outer container and collar of the previous embodiments.
- some form of external support for the liner 209 may be provided to protect the liner 209 and to improve stability when adding liquid to the reservoir and in use when the reservoir is connected to a spray gun (not shown).
- the support (not shown) may comprise an outer container and collar as described previously.
- the lid 210 may be formed with an external flange (not shown) or similar formation onto which a support sleeve or cage may be releasably secured to surround the liner 209.
- Pre-filling may be advantageous for liquids that can be stored without degrading and/or which do not require accurate colour matching such as primer paints or clearcoat lacquers. It may also be possible to store temporarily any unused liquid on removal of the reservoir from the spray gun by re-sealing the opening 230 in the lid 210 with the screw cap 238 (where provided) or any other suitable closure. This may allow the liquid to be used later by re-attaching the reservoir to the spray gun and is of potential benefit for liquids that do not cure and harden within a relatively short period of time after first use. The reservoir may be collapsed to remove any air prior to attaching the screw cap 238. In this way, the life of the stored liquid may be extended.
- FIG. 14 and 15 there is shown an alternative cap member and inlet adaptor for use with the reservoir of the present invention.
- like reference numerals in the series 300 are used to indicate parts corresponding to the previous embodiments and the construction and operation of similar parts will be readily understood from the description already given and will not be further described in detail.
- the cap member 332 for connecting the reservoir (not shown) to the spray gun (not shown) is provided with releasable connector means separate from the spout 315.
- the connector means comprises a pair of hook members 339, 340 arranged on opposite sides and spaced from the spout 315.
- Each hook member 339, 340 is similar and has an enlarged head 341, 342 respectively with a chamfer face 341a, 342a terminating at an undercut rib 341b, 342b.
- the inlet adaptor 318 on the spray gun has an external flange 343 at the outer end for co-operating with the hook members 338, 339 to secure releasably the reservoir to the spray gun with the spout 315 received in the socket 319.
- the spout 315 has external annular ribs 344 that provide a fluid-tight seal within the socket 319. It will be understood, however, that any suitable sealing means may be provided such as one or more O-rings in the socket 319 and/or on the spout 315.
- the flange 343 comprises four arcuate recesses 345, 346, 347, 348 uniformly spaced in a circumferential direction around the outer periphery such that the recesses 345, 347 are opposite each other and the recesses 346, 348 are opposite each other.
- Each recess 345, 346, 347, 348 leads in a clockwise direction (as viewed in Figure 15) via a cam lobe 345a, 346a, 347a, 348a at the end of the recess 345, 346, 347, 348 to a flat 349, 350, 351, 352 that terminates in an abutment 349a, 350a, 351a, 352a.
- the hook members 338, 339 are aligned with a pair of opposed recesses 345, 347 or 346, 348 in the flange 343.
- the spout 315 is then pushed into the socket 319 so that the enlarged heads 341, 342 at the distal ends of the hook members 338, 339 pass through the aligned recesses 345, 347 or 346, 348.
- the cap member 332 is then rotated relative to the inlet adaptor 318 to cause the hook members 338, 339 to ride over the cam lobes 345a, 347a or 346a, 348a and locate locking ribs 341b, 342b of the heads 341, 342 behind the flats 349, 351 or 350, 352. In this way, the cap member 332 is secured to the inlet adaptor 318 and axial separation of the cap member 332 from the inlet adaptor 318 is resisted. The cap member 332 can be detached from the inlet adaptor 318 by reversing the above operation.
- the opening 430 in the lid 410 is provided with an internal screw thread 450 and the base of the cap member 432 has a spigot 451 with an external screw thread 452 that is engageable with the screw thread 450 to secure releasably the cap member 432 to the reservoir.
- the lid 510 and cap member 532 are provided with complementary formations engageable with a snap action to secure releasably the cap member 532 to the reservoir around the opening 530.
- the complementary formations comprise an external rib 560 on spigot 531 and an internal groove 561 in socket 534. It will be understood, however that any suitable formations may be employed.
