Definitions

  • vaporizable products such as liquid insecticides, hair spray, deodorizers and soluble materials are easily dispensed.
  • Suitable carriers which are miscible with the vaporizable products or which are capable of dissolving the soluble materials are packed in the container along with a propellant, such as a compatible gas or Freon, and caused to pass through a simple orii e in the spray head.
  • a propellant such as a compatible gas or Freon
  • paints and enamels have been successfully dispensed from pressurized containers through the use of a valve mechanism which includes a spray tip having a depending stern provided with a slot at the bottom of the stem. This stem enters the socket of a valve member and the slot is placed in communication with the interior of the container as the valve member is unseated from the bottom surface of an annular gasket through which the stem extends.
  • Such spray heads are provided with external discharge orifices of more or less conventional construction, but for the most part paints and enamels have the pigment materials finely ground and carried in volatile vehicles easily vaporized and carrying the paint particle with them. Although practically liquid when reaching the orifice, the paint and its carrier practically explode out of the discharge orifice due to the sudden expansion of the volatile carrier.
  • the invention herein provides the solution to these problems by rapidly rotating the mixture as it passed through and out of the spray head, whereby to produce the swirling spray.
  • Many known spray heads have been devised whose purpose has been to produce swirling sprays, but so far as known, these have not been successful in the dispensing of heavy materials with proper dispersion and control, and without having the passageways of the spray head clog and render the same useless.
  • a pressurized mixture or to a propelled mixture By this it is intended to mean the total of the material and vehicle with proellant, if any is occluded, that passes through the valve structure and through the spray head.
  • proellant if any is occluded
  • Such a propelled mixture for example might consist of a suspension of fine wax particles and an abrasive in a water vehicle with gas or compressed air to a small extent occluded in the water.
  • the propellant is in a gaseous state above the vehicle and heavy material and the mixture which is forced out has none of the propellant.
  • a small quantity of propellant may be introduced directly through the valve to give added drive to the mixture passing to the spray head.
  • Still a further object of the invention is to provide a spray head for use with a pressurized container that enables the dispersion of pressurized mixtures carrying heavy materials, the said spray head being constructed of a minimum of simple and economically produced parts, easily assembled.
  • Still another object of the invention is to provide a spray head which will produce a discharge in the form of a swirling spray for the dispersion and nebulization of pressurized mixtures of heavy materials in which the spray head may readily be constructed to be associated with different constructions of valve mechanisms.
  • FIG. 2 is a similar view, but somewhat exploded, showing the insert out of engagement with the spray head.
  • FIG. 3 is a median sectional view through the spray head, with the insert poised in exploded relation thereto, the section through the insert being taken generally along the line 33 of FIG. and in the indicated direction.
  • FIG. 5 is a rear view looking into the insert, the flat face to be described being considered the front thereof.
  • FIG. 6 is a sectional view through the spray head insert taken generally along the line 6-6 of FIG. 5 and in the indicated direction.
  • FIG. 7 is a fragmentary sectional view of the spray ahead with the insert in permanent connection therewith taken generally along the line '77 of FIG. 4 and in the direction indicated.
  • FIG. 8 is a sectional view similar to that of FIG. 4 but on a reduced scale and illustrating a modified form of the invention.
  • FIG. 9 is a front-on elevational view of the spray head of FIG. 8 but with the insert removed.
  • the invention is characterized by the provision, in a spray head for use with a pressurized container for di pensing a pressurized mixture including a heavy material, of a horizontal post formed in the spray head coaxial with an annular cavity and having an insert or face piece engaged in the cavity upon the post and cooperating therewith to provide passageways leading to a first swirl chamber which gives an initial rotative motion to the propelled mixture.
  • This chamber is called the swirl-forming chamber.
  • the rotating mixture passes to a second swirl chamber which smooths out or filters the rotative motion and discharges the same at a high velocity to the atmosphere by way of an externally opening orifice.
  • the second chamber is called a swirl-smoothing chamber herein.
  • the chambers and orifice are coaxial with the post.
  • the post is provided with an extension thereof of reduced diameter that extends through the center of the swirl-forming chamber and part way into the swirl-smoothing chamber to define the inner face of the latter chamber and likewise to define the restricted entrance to the swirl-s
  • FIGS. 1 and 2 there is illustrated a spray head 10 constructed in accordance with the invention, here shown mounted upon a valve structure designated generally 12 (FIG. 4) that is carried within a pressurized container 14.
  • the container 14 consists of a canister or bottle having a cover member 16 secured over the top thereof.
  • the cover member 16 is of sheet metal suitably stamped and shaped to provide a central boss or pedestal formation 18 having a coaxial central aperture 20.
  • An annular rubber gasket 22 is clamped in position inside of the pedestal formation 18 with its central opening 36 coaxial with the aperture 2'3.
  • the valve structure 12 includes a valve plunger 13 that is normally biased upward by means of a coiled spring 24 contained within the valve housing 26.
  • the upper flanged end 28 of the valve housing is crimped as at 30 to the bottom of the gasket 22.
  • the valve member 13 is intended to ride up and down inside of the valve housing 26, and has a shoulder 34 formed on its upper end which engages the bottom of the gasket 22 about its central opening 36 in valve seating relationship.
  • the spray head it? has a depending stem 38 which slidingly and yet sealingly engages through the said central opening 36 of the gasket 22 in operating the valve structure.
  • the bottom end of the stem is provided with an axially extending slot 44 that is open through the wall of the stem and extends upward into the gasket 22 a slight distance, short of the upper face of the gasket when the valve member is seated.
  • the slot 40 may have a strengthening web formed therein as at 42.
  • the stem 38 is hollow, as shown, providing a central conduit 44.
  • the shoulder 34 will be unseated from the bottom of the gasket 22 and access will be had for the propelled mixture coming up from the bottom of the container 14 by way of the dip tube as into the interior chamber 47 of the valve housing 2d.
  • the mixture will pass up alongside of the valve member 13, past the shoulder 34 into the slot 4t) and up into the conduit 44 to be dispensed.
  • the spray head 10 may be used with mixtures other than having heavy materials, and in such case the conduit 44- serves as an initial expansion chamber. Otherwise the mixture passing through the conduit will probably be in liquid condition.
  • the arrows of FIG. 4 shows the path taken by the propelled mixture, although the valve is closed in this view and it should be understood that the unseating of the shoulder 34 is necessary before any material may be dispensed.
  • additional drive for the propelled mixture may be provided by introducing a small quantity of propellant to the chamber 47 by Way of a small opening 45.
  • the construction of the spray tip or spray head 10 comprises the essence of the invention.
  • the body 43 of the spray head 1% may have portions thereof hollowed out as at St to lighten the same and so as to minimize the amount of material needed to mold the same, but this is not essential.
  • the conduit 44 continues well up into the head almost to the top thereof as shown at 52 and opens to a horizontally arranged elongate annular cavity 54 with which it communicates at the entrances 56 and 58.
  • the cavity 54- is formed by virtue of a central cylindrical post all integral with the spray head coaxial with the cavity 54, the said post 60 having a small cylindrical extension or projection 62 located at its outer end coaxial with the post 649.
  • This extension or projection 62 is an important element of the invention and may take various forms. While shown integral with the post 60 and the post being shown integral with the head, these parts may be molded or formed separately and assembled to the head it It is most economical and preferable to mold the head with the post 6d and the projection 62 in a single step as an integral piece.
  • the projection 62 is called a mandrel herein for reasons which will appear.
  • a cup-shaped piece or insert as it will be mentioned hereinafter, is designated generally as 64, the same being frictionally engaged within the cavity 54, with the open end engaged upon the post 6%.
  • the open end is considered the rear of the insert while the closed end is considered the front or face of the insert.
  • the insert 54 has a base wall 66 and an annular side wall 68 whose dimension in diameter is so related to the inner diameter of the cavity 54 as to form a tight fit in the cavity.
  • the cavity 54 may be provided with a very small annular bead 76 so that when the insert 64 is forced into position, the bead 70 will dig into the side wall 68 and through cold flow eventually permanently seat therein forming a very effective seal. Obviously the pressures of the propelled mixture might otherwise blow the insert 64 out of the cavity 54.
  • the cavity 54 is slightly enlarged at 71 to facilitate entrance of the insert 64.
  • FIGS. 3, 4, 5 and 6 illustrate the insert.
  • the base wall 66 of the insert has a blank or flat front face 72 with a center opening 74 that forms the exterior metering orifice. The mixture will be sprayed or nebulized out of this orifice 74.
  • the chamber 76 is shown here as generally square but has four tangential branches or channels as shown at 79, 86, 82 and 34.
  • the chamber '78 is annular and communicates directly with the chamber 76. Both chambers 76 and 78 are formed in the base wall 66 during the molding of the insert 64.
  • the construction described gives rise to four triangular formations 86, 88, 90, and 92 at the bottom of the insert presenting flat transverse surfaces to the rear open end of the insert 64.
  • the hypotenuses of these triangular formations are extended substantially throughout the length of the insert 64 in an axial direction, considering the axis of the external metering orifice 74 and the swirlsmoothing chamber 78 so that the resulting walls have a cross section somewhat like the chorded segments of a circle, and the overall cross-sectional configuration on the interior of the insert is square with slightly angled corners.
  • the wall surfaces resulting from this structure are designated 94, 96, 98 and 160.
  • these walls are flared outwardly producing chordsegment-shaped slanted surfaces 162, 104, 166 and 168.
  • the slanted surfaces present guiding surfaces to flow of propelled mixture.
  • the chamfered edge 169 assists ready installation of the insert 64.
  • the post 60 is of an external diameter which is substantially the same as the distance across the flats of the square, that is the distance between opposite walls 94 and 98 for example.
  • the extension 62 passes fully through the chamber 76 and partially into the chamber 78. Propelled mixture entering the entrances 56 and 58 into the cavity 54 will be passed along the four irregularly shaped passageways 110, 111, 112 and 113 to the grooves '79, 8t), 82 and 84. It will be appreciated that these grooves will be covered or enclosed adjacent the chamber 76 by virtue of the end face 114 of the post 60 engaging upon and substantially overlying the triangular surfaces 86, 8%, 9i and 9?...
  • the propelled mixture will enter the swirl-forming chamber '76 at four points tangential to the chamber thereby causing a rotative movement of the propelled mixture within the chamber 76 in a counter-clockwise direction as shown by the arrows and at considerable speed because of the small volume of the chamber 76.
  • This swirling will occur around the extension or projection 62.
  • this projection 62 is a swirl-forming mandrel and it promotes the swirl by providing a definite center about which the rotation is forced to occur.
  • the pressure of continuously entering mixture will force the swirling mixture immediately to pass into the chamber 6 78 which is preferably smaller in volume.
  • the mandrel 62 will define an annular entrance 116 (FIG.
  • the swirl-smoothing chamber 78 itself is perfectly annular in configuration whereby a mechanical filtering or smoothing out of the swirl will occur.
  • the speed of the swirl is increased because of the decreased size of the smoothing chamber 78 and therefore the material will be ejected through the external metering orifice 74 in a high speed swirl. This will result in a thorough dispersion and nebulizing the heavy material carried by the mixture.
  • the communication between the swirl-forming chamber and the swirl-smoothing chamber is at :116 which is an annular opening about the mandrel 62. It will therefore be seen that the discharge of the rotating mixture from the swirl-forming chamber occurs at locations radially spaced from the center of rotation of the swirl so that said mixture is introduced into the swirl-smoothing chamber at a considerable circumferential velocity. This is believed to be promoted by the existence of the mandrel, because the absence of the mandrel would result in a substantial quantity of mixture leaving at the center of the swirl-forming chamber in which case the actual circumferential velocity would be materially less.
  • one or two of the grooves 79, 8t 82 and 84- may clog without preventing operation of the spray head 10. Under certain circumstances, clogging of all but one groove will not prevent operation. Due to the tangential entry of the aerosol from four different points, the elimination of one or more points does not prevent the others from exerting a twisting or swirling movement about the mandrel 62. It is believed that the mandrel prevents cross currents or turbulence which might equalize the rotative effect caused by the entering mixture. The non-symmetrical formation of swirling mixture in the swirl-forming chamber 76 will not be effective to prevent a swirling dispersion out of orifice 74 due to the smoothing and velocity-increasing action of the chamber 78.
  • the groove ends 79', 86', 82 and 84 are preferably rounded to eliminate pockets. Likewise the outer edge 66 of the post 61 is rounded to present smooth passage for the mixture carrying the heavy material.
  • the spray head 10 thus far described has a depending stem 38 and is suitable for use with a valve structure which is completely below the gasket 22. Such a spray head can readily be removed from the gasket and cleaned or replaced.
  • the invention is not limited to this construction, which is designed for vertical reciprocation. It may be used in structures which are intended for tilting operation and combinations of tilting and reciprocating operation. Also other types of reciprocating valves may be used.
  • the spray head is shown mounted on an assembly including a cover member 16 and valve structure 32. Note that the assembly is shown not associated with a canister or bottle. This is the form in which the structure is sold to packers of pressurized products, either with or without the spray head in place. The curled lip 16' with gasket compound 17 in place will be worked onto the container by the filler.
  • Spray head 150 differs from spray head 10 only in one respect. Instead of an integral stem 38, spray head 150 has a socket 152 and the valve structure 32' has an integral valve member 154 that has a lower plunger portion 13 and an upper tubular part 38.
  • the tubular part 38 protrudes through the aperture 36 in gasket 22 as seen in FIG. 8 and presents a hollow stem above the pedestal 18.
  • the center of the hollow bore 156 is closed at its lower end, and open at its top end.
  • There are one or more transverse passages 158 at the bottom of the bore '15'6'adjacent the closed end which are normally externally blocked by gasket 22.
  • Spring 24 riding in housing 26 pushes on the bottom of the plunger portion 13 to drive the shoulder 34- into valve seating engagement with the gasket 22.
  • Spray head 150 Pressing down on spray head 150 in turn pushes the valve member 154 down relatives to the gasket 22 carrying the passages 153 below the gasket to establish communication between the chamber 47 and bore 156.
  • a small head in socket 152 (not shown) similar to head 70 may be used.
  • the insert 64- and post 64 are identical in construction and operation to those of the spray head 10.
  • the hollow stem 38 may be tilted to cause dispensing of the mixture, although this structure is primarily intended for vertical reciprocation.
  • valve structures are made of metal or plastic.
  • valve housings such as 26 are of metal or plastic; the valve member 16 of FIG. 4 is usually of plastic; the valve member 15'4- of PEG. 8 is of plastic or metal; the gasket 22 is usually of rubber or synthetic rubber.
  • the cover members .16 are most practically of sheet metal to permit easy forming in stamping machines and to enable crimping or other securement processes.
  • the spray heads and 150 ad their inserts are preferably molded of plastic although the use of die cast metals or machined parts is not outside the scope of the invention. The greatest economy is achieved by the use of molded plastics.
  • the swirl-forming chamber 76 and the tangential channels 759, 80, 82 and 84 could be made in such a manner that the channels spiral radially outward and the chamber '76 itself is more rounded so that the flow of the propelled mixture is smoother into the chamber. Dies to make such structures would be more difficult and expensive to make, but would operate in accordance with the theory of the invention.
  • the swirl-smoothing chamber 73 could be a continuation in an axial direction of the swirl-forming chamber 76 with the walls gradually tapering and with no sharp entrance corners, this being a result of more intricate detail in the molding cavities.
  • the mandrel 62 would not necessarily be cylindrical but might more effectively be tapered or follow in configuration the walls of the combined chambers, being suitably spaced therefrom to achieve the desired effects.
