Definitions

  • the invention relates to paint spraying equipment such as used In the car refinishing Industry.
  • Car paint finishes are commonly replaced or renewed by their owners either to change a vehicle's colour or to provide a new finish to palntwork which has suffered damage, discolouration and general wear and tear.
  • paint refinishing operations have employed cellulose paint finishes which are sprayed from a conventional air spray gun and left to dry In the air to a hard finish.
  • Chem I cally-curring finishes have gradually replaced cellulose paint finishes since Introduction of the former some years ago.
  • These finishes comprise materials which cure by chemical change rather than simply by solvent evaporation and offer the advantage of speedy refinishing, hard surface finish and reductions in the level of fumes and vapours compared to that derived from conventional paint vehicles, such as the volatile organic solvents used In cellulose paints.
  • Spraying equipment used In car refinishing usually comprises a nozzled gun head supplied by Venturi effect via a tube from a reservoir of paint or other liquid coating composition contained In a cylindrical cup or pot to which the gun head Is mounted.
  • the supply tube Is disposed In the cavity of the cup with its lowermost end opening within a body of the paint.
  • the tube Is bent towards one side of the cavity so that when the cup is tipped with Its normally vertical axis no longer vertical, the risk that the level falls beneath the tube opening Is minimized.
  • the tube Is of course, also sufficiently long that Its opening is as close as possible to the base of the cup. However, there is commonly sufficient clearance that a fitter body of some kind can be mounted to the terminus of the supply tube In the clearance space.
  • the above practice obviously reduces the volume of paint or other liquid which must remain In the cup to allow spraying to continue.
  • the minimum required volume is obviously important in as much as it determines the amount of paint required to be charged to the cup In excess of that required by the surface to be coated. The amount has particular significance In the context of chemically-curing surface coating materials where the resulting materials wastage would otherwise Involve a real level of unnecessary cost.
  • an apparatus for spraying paint or other liquid material which apparatus comprises a container for said liquid material, said container having an access opening to Its cavity for charging of said liquid material thereto and a removable closure member for said opening, and a fluid supply tube penetrating said container and having an end opening Into said cavity and so disposed as in use to be adjacent the bottom of a body of liquid contained In said cavity, characterized
  • said container has a non-uniform cross-sectional area decreasing to a minimum In the viclnity of the fluld supply tube open end whereby the ratio between volume and depth of liquid material in the container cavity when the level of said liquid material Just reaches the fluid supply tube open end Is preferably minimized but In any event reduced compared to a uniform cross-sectioned container of the same maximum cross-section.
  • the liquid material container will in general take the form of a cavity-defining member supported within a conventional paint sprayer container of, for example, right circular cylindrical form and made from metallic material such as aluminium or aluminium alloy.
  • a conventional sprayer container may, of course, be entirely omitted In some embodiments of the invention.
  • the form of arrangement Just referred to Is much preferred since a simple accessory member, for example, of moulded plastics material, can easily and economically be made to be Inserted Into conventional spray containers so that the existing equipment can be fully relied on for Its proven design of closure and fluid supply tube arrangements.
  • the apparatus comprises a main container of preferably right circular cylindrical form, the main container having a top equipped with a closure member removable to allow access to the container cavity and a base, a vessel supported within the main container cavity and having a cross-section at its upper extremity preferably approximating that of the adjacent cavity-defining walls of the main container, the vessel having a smaller cross-sectional area at the lower extremity of the vessel.
  • the reduced cross-sectional area at the lower extremity of the vessel I (or the minimum area) will I conveniently be not more than 45% of the cross-sectional area of the container at Its base.
  • the ratio will generally be 35% or less (eg. not more than 25%), preferably less than 20% (eg 15% or less, most preferably a figure in the range from 8% to 14% such 10% approximately).
  • the reduced cross-sectional area may, for example, be a circular area not more than 25 or 30 times (eg 10 to 20 times) such as about 12 to 25 times larger In diameter than the opening of the fluid supply tube (typically about 15 times larger), the circular area being measured at the level of a body of liquid Just covering the tube opening.
  • the Internally supported vessel may convenlently be made of a coating composition-resistant plastics material such as a polyethylene or polypropylene (or copolymer).
  • a coating composition-resistant plastics material such as a polyethylene or polypropylene (or copolymer).
  • the vessel is most conveniently made by Injection moulding and thus Its material will preferably be selected with this In mind.
  • the vessel should normally be self-supporting In use conditions when charged with a body of paint so as to be dimensionally and configurationally stable, at least at the lower extremity.
  • the apparatus shown in the drawings comprises a 106mm Internal diameter aluminium pot 1 of right circular cylindrical form, as conventionally used In paint spraying equipment. Supported through the open top of the pot is a 39mm Internal diameter Injection moulded polyethylene vessel 2 having 1mm thick walls. The flanges 3 and 4 of the latter locate over the upper rim of pot 1, cut-out 15 being received over pot lugs 12. A conventional-type lid 6, also of aluminium, sealingly engages by a seal (not shown) the flange 4 of vessel 2. A 10mm Internal diameter fluid supply tube assembly 7 penetrates central opening 8 in lid 6 so as largely to reside In the cavity 5 of vessel 2 and is also conventional for use In paint spraying equipment.
  • Vessel 2 has an external circular cross-section at Its upper end which Is approximately equal to the Internal cross-section of container or pot 1.
  • the cross-section of vessel 2 reduces downwardly until I It Is a fraction of this value at the region of the end opening of tube 7, as will be evident from Figures 2 and 3 In particular.
  • Vessel 2 Is configured to accommodate the bend In tube 7, as best seen In Figure 2.
  • a yolk 9 is received over the top portion of the tube assembly 7 and Is located and restrained against rotation relative to the lid 6 and assembly 7 by diametrically opposed flats 13 of assembly 7 and cooperative parts of the yolk aperture, as will I be evident from Figure 1.
  • Arms 10 of yolk 9 extend downwardly and Include slotted extremities 11 which engage lugs 12 of the container 1, the latter being fixed In the wall of pot 1 by heads of caps 20 present In both the Figure 1 and Figure 4 embodiments but Illustrated only In Figure 4.
  • the lugs 12 are entered Into slots 1 1 by appropriate rotation of 11d 6, assembly 7 and yolk 9 relative to the pot 1, following which operation of cam lever 14 urges the yolk 9 upwardly by cooperation of Its rotating cam surfaces with those of the yolk.
  • the volume of paint or other liquid material In the vessel 2 can, as will I be appreciated, reach a very low level (typically 4ml In the case of the apparatus shown In Figures 1 to 3), whilst remaining above the opening In tube 7. This enables spraying to be effected with little wastage of materials and thus no significant wasted expenditure.
  • the vessel 2 has a front face inclined to the wall surface of container 1, It is thought that a vessel having a vertical I front wall I (ie generally parallel to the container 1 wall) will be easier to make by injection moulding. Such form Is therefore preferred and Is I lustrated in Figure 4 of the drawings in which as compared to Figures 1 to 3 like parts are designated by like reference numerals.
  • the vessel 2 of Figures 1 to 3 is replaced by an alternative vessel of the same material but having an upper relatively thick wailed portion 19 of uniform right circular cylindrical form and a lower relatively thin walled portion 18 of non-uniform cross-section and Inclined axis.
  • Portion 19 has an out-turned flange which seats upon and seals with the top rim of pot 1 In similar fashion to flange 4 of the apparatus shown In Figures 1 to 3 but has no counterpart to flange 3 shown In Figure 1.
  • a recess 21 is formed at each of two diametrically opposed sides in the thickness of portion 19, recesses 21 cooperating with caps 20 of lugs 12 to support the polyethylene vessel within the cavity of pot 1 In similar fashion to the arrangement shown In Figures 1 to 3.
  • Lower cylindrical vessel portion 18 has a flat circular base 22.
  • the remainder of the portion 18 rises from base 22 as a wall which is perpendicular at 17 and increasingly obtusely angled relative to the base 22 with increasing angular separation from the perpendicular wall portion.
  • two spaced parallel axes penetrate the centre of base 22 on the one hand and the centre of the circular open top of portion 19 on the other.
  • Tube 7 Is received In the vessel In similar orientation with respect to the vessel as that depicted In Figures 1 to 3.
  • Base 22 has an area of approximately 25% of the I nterna I area of the opening Into thick walled portion 19 of vessel 2, the latter conveniently being of the order of 50 sq.cm.
  • the invention Includes within its scope a self-supporting container for paint and the like comprising a moulded plastics material member defining a cavity within cylindrical side walls which rise from a generally circular or eliptical flat base, the member having an outwardly flanged lip formed at Its upper extremity and defining a generally circular opening Into the cavity, the base having a surface area Internally of the cavity equal to less than 35% of the cross-sectional area of the circular opening defined at the upper extremity of the moulded member and the cylindrical walls rising perpendicularly from the base at a first Junction of walls and base and rising with an obtuseness of angle at other Junctions which Increases with spacing from said first Junction.
  • Such a container may, for example, be Injection moulded, the cylindrical side walls Including an upper portion adjacent the upper extremity of the moulded member, said portion having a uniform cross-section and being moulded with a pair of diametrically opposed location recesses formed In the thickness of the plastic material of the moulded member on the exterior thereof, the base having a surface area Internal ly of the cavity equal to 15% to 25% of the cross-sectional area of the circular opening defined at the upper extremity of the moulded member.
