Abstract
A single use, disposable reservoir (30) of low volume for use in conjunction with a spray gun (1) for spray painting small areas, for example 'spray out' cards for colour matching a paint mix for spray painting a vehicle. The reservoir (30) is in the form of a syringe body (32) with a plunger (34) having a sealing member (54) slidable within the body (32) for drawing paint (57) into the body (32) via an open end (38). The body (32) has an aperture (42) adjacent to a closed end (36) and the plunger (34) can be moved to position the sealing member (54) between the aperture (42) and closed end (3 6) for releasing a partial vacuum created when the paint (57) is drawn into the body (32) and allow the paint (57) to be withdrawn, in use, when the reservo ir (30) is connected to a spray gun (1) without actuating the plunger (34). In other embodiments, the reservoir (60;80) comprises a concertina-type body (6 6) or a pipette body (82).
Claims (20)
1. A fluid reservoir for a spray gun, the reservoir (30;60;80) comprising a body (32;66;82) having a first, substantially closed end (36;64) and a second, open end (38;68;91), the open end (38;68;91) being connectable, in use, to a spray gun (1), and a vacuum forming element (34;64;84) operable to create at least a partial vacuum within the body (32;66;82) for drawing fluid (57;74;108) into the reservoir (30;60;80) via the open end when disconnected from the spray gun (1) characterised in that means (42;59,59a;66;104) is provided for controlling said at least partial vacuum whereby, when the open end (38;68;91) of the reservoir (30;60;80) is connected to the spray gun (1), fluid (57;74;108) can be withdrawn from the reservoir (30,60,80) via the open end (38;68;91) for supply to the spray gun (1) independently of an actuation force applied to the vacuum forming element (34;66;84) externally of the reservoir (30;60;80).
2. A fluid reservoir as claimed in Claim 1 wherein the body (32) is a syringe body and the vacuum forming element (34) is a plunger having a sealing member (54) resident in the body (32) and a shank (52) passing through an opening in the first end (36).
3. A fluid reservoir as claimed in Claim 2 wherein the sealing member (54) slidably and sealably engages a wall (44) of the body (32) to divide the syringe body (32) into two chambers (40a and 40b), and movement of the plunger (34) away from the second, open end (38) towards the first end (36) creates the at least partial vacuum in the body (32) for drawing fluid (57) into the reservoir (30).
4. A fluid reservoir as claimed in Claim 2 or Claim 3 wherein the means (42) for controlling the at least partial vacuum comprises an aperture (42) through a wall of the body (32) proximate the first end (36) of the body (32) such that, in use, the sealing member (54) can be moved away from the second, open end (38) to a first position between the second, open end (38) and the aperture (42) to draw fluid (57) into the reservoir (30) and to a second position between the aperture (42) and the first, closed end (36) to allow fluid to be withdrawn from the reservoir (30) via the second, open end (38).
5. A fluid reservoir as claimed in Claim 2 or Claim 3 wherein the means (59) for controlling the at least partial vacuum comprises a passageway (59) extending through the plunger (34) from the sealing member (54) within the body (32) to a position externally of the body (32), and a releasable closure (59a) for opening/closing the passageway (59) such that, in use, the passageway (59) is closed by the closure (59a) to allow fluid (57) to be drawn into the body (32) by movement of the sealing member (54) away from the second, open end (38) and is opened by releasing the closure (59a) to allow fluid (57) to be withdrawn from the second, open end (38).
6. A fluid reservoir as claimed in Claim 1 wherein the body (66) is a collapsible concertina-type body (66) of which the first, closed end (64) constitutes the vacuum forming element such that fluid (74) can be draw into the body (66) by the partial vacuum created by movement of the closed end (64) away from the open end (68), and the means (66) for controlling the partial vacuum is provided by the collapsible body (66).
7. A fluid reservoir as claimed in Claim 1 wherein the body (82) is a pipette (82) having a filler (84) at the first, closed end providing the vacuum forming element for drawing fluid (108) into the body (82), and valve means (102,104) for controlling the partial vacuum to allow the fluid (108) to be withdrawn from the body (82).
8. A fluid reservoir as claimed in any one of the preceding claims wherein the second, open end (38;68;91) of the body (32;82) is provided with a mounting (46;70;92) adapted for releasably connecting the second, open end (38;68;91) to a spray gun (1) in use or a closure (118;122;126) for sealing the reservoir (30;60;80).
9. A fluid reservoir as claimed in Claim 8 wherein an adapter (55;55a;55b) is provided for releasably attaching the mounting (46;70;92) to a spray gun (1), in use.
10. A fluid reservoir as claimed in any one of the preceding Claims wherein the reservoir (30;60;80) has a volume of at least 100ml.
11. A fluid reservoir as claimed in any one of the preceding Claims wherein the reservoir (30;60;80) is a single-use, disposable reservoir (30;60;80).
12. A fluid reservoir as claimed in any one of the preceding Claims wherein the reservoir (30;60;80) substantially prevents the escape of solvent vapour from a solution, or mixture, in use.
13. A fluid reservoir as claimed in any one of the preceding Claims wherein the body (32;82) is substantially made of a plastics material.
14. A fluid reservoir as claimed in Claim 13 wherein the body (32;82) is substantially transparent or translucent or has a transparent or translucent window and is provided with a scale marking to indicate a volume of fluid within the body (32;82).
