Definitions

  • This invention relates to liquid spraying devices a more particularly to devices for spraying paint and other liquids from a container or receptacle by means of a pressurized propellent gas carried within and released from a separate container.
  • aerosols are of 3, 6, 12 or l6-ounce capacity.
  • Paints are among the substances which have been extensively packaged, sold and used in aerosol cans and many colors of paint have been packaged in aerosol cans.
  • aerosol cans containing a mixture of propellent and liquid to be sprayed have not been usable in those instances wherein the propellent and the liquid are not compatible or miscible or the liquid corrodes or otherwise attacks the metal container in which the propellent is confined.
  • an improved liquid spray device which is particularly adapted for use with standard aerosol cans; which supports and holds both the aerosol can of propellent and a separate container for the liquid to be sprayed; which sprays without mixing and/ or retention of the propellent and liquid to be sprayed in a common container; which is easily and economically manufactured from plastic, as by molding, in a single unitary structure, except for fittings; which provides for ready and positive operation of the discharge valve of the aerosol can; which provides a simple, eflective and efficient sealing engagement and positioning means with the aerosol can whereby to provide for ready attachment and removal of an aerosol can While substantially preventing accidental leakage of propellent therefrom or accidental interference with the functioning or operation of the valve mechanism; which is pleasing in appearance and safe and efficient in use and operation; which is compact and provides a relatively short passage for the propellent between the aerosol can and container of liquid to be sprayed; which does not interfere with the spray pattern of the aerosol as it issues from the de atent O" 3,044,713 Patente

  • FIGURE 1 of the drawings A complete spraying device embodying my invention is indicated generally in FIGURE 1 of the drawings, and comprises a spray head 1, an aerosol can 2 and a container 4 for the material, such as paint, to be sprayed.
  • Container 4 is preferably a small glass jar having a threaded top 5, FIGURE 3, although the spray head 1 may be used with containers made of other materials and having other kinds of tops.
  • Aerosol can 2 is of well known type comprising a body 7 having a cylindrical side wall 8 to which a concave bottom is secured, FIGURE 1.
  • body 7 In order to provide for closing can. 2 and mounting a discharge valve mechanism therein, the upper end of body 7 is shaped to provide a cylindrical wall 11 of lesser diameter than wall 8 and connected therewith by an integral conical portion 13, FIGURE 3.
  • a second, flatter conical wall portion 14 extends upwardly and inwardly from wall 11 and is crimped and doubled back at its top, as at 16, to define the mouth 17 of the can, FIGURE 4.
  • the mouth 17 is closed by a dished cover 19 which is crimped to the top of the can as at 22 and extends slightly under the doubled portion 16 as at 20.
  • the cover is embossed as at 23 to provide greater strength and is provide-d with a cylindrical central boss 25 having an apertured flange 26 through which the valve mechanism, indicated generally at 28, extends.
  • Valve mechanism 28 is of a well known type and includes a nipple 29 having a stepped cylindrical bore 31 therein, the step forming a valve seat 32, facing toward the can 2.
  • a ball type valve 34 is disposed within the inner (lower as viewed) end 35 of bore 31 and is urged into sealing engagement with seat 32 by a spring 37 which seats upon an inturned flange 38 formed at the inner end 40 of nipple 29.
  • Valve 34 is preferably provided with a projection 41 which extends into spring 37 and centers the valve and spring. The released propellant exits through the open end 42 of nipple 29 or the orifice 43 which intersects the outer (upper as viewed) end 44 of bore 31.

  • a connecting bridge or structural portion 64 extends between the cavities.
  • Bridge 64 provides the body with suflicient rigidity and structural strength to support the can 2 and container 4 and so that the assembly can be readily handled.
  • a transverse bore 66 extends through bridge 64 for conducting the propellant from the can 2 to an orifice 67 through which the liquid to be sprayed is drawn from container 4 by the stream of passing propellant.
  • Orifice 67 is preferably formed in a metal fitting 70 which is pressed into an opening in body 55 and extends into cavity 61 and the liquid to be sprayed is conducted to fitting 70 through a plastic tube 71 extending to a point near the bottom of the container.
  • Bore 66 preferably terminates in a nozzle 73 formed in a separate fitting 75 and adapted to direct a stream of propellent over orifice 67 so that the reduced pressure over the orifice coupled with the atmospheric pressure exerted on the liquid in container 4 through aperture 76 (see FIGURE 2), causes the liquid to flow from container 4 into the stream of propellent by which it is atomized and carried away.
  • a gasket 78 is preferably provided within cavity 61 between the top 79 of the container 4 and a suitable seat 80 formed integrally with body 55.
  • cavity 60 is adapted to engage over the top of the can and is defined in part in body member 55 by a cylindrical straight wall 81, FIGURES 3 and 5, which is of somewhat greater diameter and less height than wall 11 of can 2.
  • the interior of wall 81 is provided with a plurality of radially spaced, axially extending ribs 82.
  • the inner surfaces of the ribs define a diameter slightly less than the diameter of wall 11.
  • the ribs and wall 8 1 are somewhat distortable; thus the spray head body 55 is able to make a proper frictional engagement with cans of propellent even though the walls 11 of the cans are out of round or of varying diameter within ordinary commercial tolerances.
  • Cavity 60 is also defined in part by a conical wall 83, FIGURES 3 and 4, which is complementary to and disposed adjacent to and preferably in slightly spaced relationship with wall 14 of can 2 when the can is properly seated in cavity 60.
  • Cavity 60 also includes an inner shallow cylindrical portion 84, FIGURE 4.
  • Portion 84 of cavity 60 is defined by a cylindrical side wall 86, which surrounds and is preferably slightly spaced from the crimped portion 22 of cover 19.
  • a flat transversely extending wall 87 extends inwardly from side wall 86 and has a depending central boss 89 having a flat seat 90 which is adapted to engage the apertured flange 26 of cover 19 when can 2 is properly seated in cavity 60.
  • Cavity 60 also includes an inner relatively deep cylindrical opening 92 extending inwardly (upwardly as viewed) from seat 90 and defined by side wall 93 and top wall 94.
  • the side wall 93 is adapted to enclose and tightly engage nipple 29 between flange 26 and groove 46 so as to prevent leakage of the propellent from the spray head except along the desired escape path.
  • Bore 66 inter sects opening 92 in approximate lateral alignment with groove 46 and when the valve is open the propellent flows into bore 66 either over the upper end of nipple 29 and through the clearance space between the wall 93 and the upper portion 95 of the nipple 29, which portion is of slightly reduced diameter, or through orifice 43.
  • the top wall 94 above bore 93 is pierced and a push rod 96 is positioned therein.
  • the push rod 96 frictionally engages the pierced opening in the wall 94 so that it remains in place when the spray head is separated from the can tube.
  • the push rod 96 extends into the open end 42 of the nipple 29 to a position where it can engage the valve 34.
  • the push rod is of sufiicient length to extend between the top of the valve 34 and into the notched opening 97 in the projecting top 98 of the spray head.
  • the notch 97 makes the top 98 into what is in efiect a hinged flap so that the user may, without difiiculty, press the top downwardly into engagement with the rod 96 and thus move the rod 96 downwardly to move the valve 34 from its seat and discharge the propellent gas from the can.
  • the movement required to remove the valve 34 from its seat is smallof the order of A; "so that the device can be operated easily and without fatigue on the part of the operator.
  • the fit between the rod 96 and the pierced opening in the top 94 is snug enough to prevent any substantial leakage of propellent around the rod, but the spring 37 is strong enough to overcome the frictional engagement between the rod 96 and the pierced opening and close the valve whenever the flap 98 is released.
  • the upper surface of body 55 above the container 4 is sloped downwardly beyond the nozzle 73 and orifice 67 as shown. It will be noted that the fitting 70 and the tube 71 which carry the material to be sprayed to the orifice 67 are offset from the center of the container 4 toward the can 2. This provides a more compact construction and makes the bridge 64 shorter than would be required if the tube 71 were centrally located in the container 4.
  • the fitting 75 is provided with a metering orifice and a small expansion chamber as shown in FIGURE 6.
  • the fitting 75 consists of a hollow cylindrical member which fits snugly within and projects from the outer end of bore 66.
  • the fitting has a small plastic insert 103 providing a metering orifice 104 at its inner end, an expansion chamber 105 in its central portion, and an end wall 106 through which the orifice constituting the nozzle 73 extends.
  • the provision of the two orifices with the expansion chamber 105 between them results in more accurate outlet metering of the flow of propellent gas and, as noted above, greater efliciency of use of propellent in discharging the material to be sprayed.
  • Efiiciency in operation requires that the nozzle 73 and the orifice 67 be disposed accurately with respect to each other. In the present design this is accomplished easily because the bore 66 and the opening in which the fitting 70 is disposed are accurately located in the molded plastic body member 55 by the die used in the molding operation.
  • the fitting 7t) and the fitting 75 are small screw machine parts that can be formed with a high degree of accuracy.
  • the fitting 70 is provided with a horizontal shoulder 167 surrounding the orifice 67 so that in assembly it is only necessary to insert the fitting 75 into the bore 66 to the correct depth and then push the fitting 70 upwardly through the opening in the body member 55 until the shoulder 107 engages the end of the fitting 75 as shown.
  • the orifice 67 and the nozzle 73 are accurately aligned with respect to each other in both vertical and horizontal directions.

  • Nozzle 73 is then directed at the object or place to be sprayed and the user presses on flap 98 with his thumb or forefinger, as the case may be, to push down 7 on rod 96 and thereby displace valve 34 inwardly against the force of spring 37 to release the propellent.
  • the propellent travels up bore 31, through the end of nipple 29 or orifice 43, and thence along bore 66, expands through orifice 104 into the expansion chamber 105 and issues at high velocity from nozzle 73.
