Definitions

  • buttons for aerosol valves in which the spray orifice of the button is normally blocked or closed in the non-dispensing condition of the valve, there being a diaphragm in the button which is flexed by admission of aerosol fluid under pressure when the valve is opened to unblock the spray orifice and allow discharge of the aerosol fluid, the blocking of the spray orifice reoccurring automatically upon subsidence of fluid pressure when the valve is closed.
  • This invention relates to nozzles for fluid dispensing
  • spray-actuators which provide for finger operation of the typical valve of the so-called aerosol or self-pressurized dispensing packages
  • pump type dispensing packages employing a manually operated plunger pump, to effect discharge of fluid product stored in the packages.
  • Spray-actuators of the type here concerned commonly take the form of molded plastic buttons of various shapes and sizes to permit one-finger operation of the valve or plunger of the dispensing package.
  • the button is provided with a socket for receiving the tubular stem of the typical aerosol valve or plunger pump type, and with a discharge orifice communicating internally of the button with the stem-receiving socket to direct and control the delivery of the fluid product from the container in a desired manner.
  • This delivery of the product may be in the form of a fine spray or mist, drops, foam or solid stream, depending on the nature of the product and the purpose to which it is to be applied.
  • the problem of plugging of the terminal orifice is still encountered under certain conditions and it is a purpose of the present invention to overcome the prior difficulties by a button of new and different design.
  • the invention herein disclosed contemplates a spray button having a main body and an orifice plate preferably formed of molded plastic. Suitable provision is made in the body to secure it to a valve stem or pump plunger tube to effect delivery of fluid to the 3,437,270 Patented Apr. 8, 1969 button from a supply reservoir.
  • An interior passage in the button body leads from the stem or tube to an outlet in a face of the button from which the fluid is to be discharged.
  • An annular abutment is disposed in the well to provide a sharp-edged recessed shoulder therein completely surrounding the center or axis of the outlet and disposed between the center and the point of inlet of the interior fluid passage to the outlet.
  • the orifice plate is of a size and shape to completely cover the outlet, being held therein only by peripheral engagement with its wall to form a fluid tight seal at that point.
  • the plate has a centrally located discharge orifice which coincides with the axis of the outlet, and the surrounding area of the plate is concave-convex and flexible, with the convex surface facing inwardly of the outlet and contacting the sharp-edged recessed annular shoulder.
  • This formation of the plate causes it to act as a Belleville or disc spring with its central portion normally biased inwardly of the outlet but having the special meta-stable characteristic of this type of spring, namely that the force necessary to move the central portion outwardly against its bias increases to a maximum as the over-center position is approached; but once that position has been passed, then a lower force is all that is needed to maintain the spring in its maximum flexed position.
  • a spring thus exhibits something of a toggle or snap action, although it will not remain in flexed, over-center position without continued application of some force.
  • the invention herein disclosed takes advantage of this disc spring principle in a unique construction of spray button wherein the orifice plate takes the form of a disc normally biased as above mentioned to abut on the sharpedge-d shoulder of the annular abutment in the well of the button. It thereby normally seals off communication between the atmosphere and the supply of fluid product to be discarged at a point close to but spaced from the discharge orifice itself. As a result, at most only a drop or two of trapped fluid is left exposed to evaporization, crystallization or polymerization in the nozzle body between periods of dispensing.
  • admission of fluid under pressure to the spray button causes that pressure to be transmitted initially to the outer flexible portion only of the diaphragm or disc, i.e.
  • the unit pressure necessary to hold the diaphragm in its flexed position can be lower than that initially required to snap it over-center. This is desirable to compensate for normal pressure drop as the fluid discharges through the orifice.
  • a peg or pin located centrally of the well in the button body so that it projects axially of, or even freely into, the discharge orifice itself.
  • a peg or pin can serve as a useful mechanical clean-out device, helping further to remove any traces of clogging residue that may be present immediately adjacent the orifice itself, as well as to reduce still further the volume of trapped liquid exposed to atmosphere at that point.
  • Such peg however cannot be used effectively as the fluid sealing member itself in place of the previously mentioned annular abutment in the outlet.
  • the ratio of diaphragm areas exposed to supply fluid pressure is appreciably different from unity in the flexed and unflexed conditions, as by placing the sealing abutment farther away from the discharge orifice in accordance with this invention, the tolerances to be maintained in production of the parts are not nearly so tight and diaphragm oscillation is much more readily avoided.
  • the invention also contemplates the incorporation of mechanical break-up means of the swirl chamber type acting on the fluid product adjacent the discharge point, whereby to effect the delivery of the product as a fine cone of spray.
  • FIG. 1 is a fragmentary view in side elevation, partly in section, of a portion of a typical aerosol dispenser and valve incorporating a spray-actuator button of the present invention
  • FIG. 2 is an enlarged vertical cross-section of the discharge orifice portion of the button seen in FIG. 1, parts being broken away for simplification of illustration;
  • FIG. 3 is a cross-sectional view taken on line 33 of FIG. 1;
  • FIG. 4 is a fragmentary cross-sectional view similar to FIG. 2, wherein the nozzle plate is shown in fluid dispensing condition;
  • FIG. 5 is a plan view looking at the inner face of the nozzle plate or insert of the previous figures
  • FIG. 6 is a fragmentary view in cross-section of a dispensing button of modified design incorporating the invention herein;
  • FIG. 7 is a plan view looking at the inner face of the nozzle plate or insert of the button seen in FIG. 6.
  • FIG. 1 there is illustrated a portion of a typical aerosol container to which is secured a valve assembly 22 of known construction having a spray-actuator button 24 incorporating the present invention, the button being mounted upon the visual hollow stem 26 of the valve assembly.
  • the fluid product to be dispensed is normally held under the pressure of a propellant gas within container 20 by means of valve 22, but is released upon actuation of the valve for dispensing from an outlet chamber or well 28 formed in a lateral face of button 24.
  • the button may convenient-1y be molded of plastic and provided with a socket 30 opening on tis under face within which stem 26 is telescopically received to form a fluid-tight connection.
  • a chamber 32 within the button 4 communicates with socket 30 to receive fluid produce delivered through the stern of the valve.
  • Button 24 incorporates an inserted flexible orifice plate or diaphragm member 36, shown in greater detail in FIGS. 2, 3 and 5, having a fine-bore discharge orifice 38 located generally centrally thereof.
  • Orifice plate 36 is of generally circular, cupped configuration and may be formed of suitable molded plastic, or of sheet metal, to provide a central, flexible, concavo-convex portion 40 immediately surrounding orifice 38.
  • member 36 has an inwardly directed flange or wall 42 which is received in and makes a fluid tight fit in outlet 28 of the button.
  • insert 36 is also provided with an inwardly directed hollow boss 44 having a central counterbore 46 concentric with and leading to discharge orifice 38.
  • four slots 48 intersect boss 44 tangentially of counterbore 46 to feed fluid to a central swirl chamber 58 immediately up stream of the orifice in order to provide a cone of fine mist when the fluid discharges.
  • diaphragm 40 Upon release of the actuator button to return valve 22 to closed position, thereby cutting off further delivery of product under pressure to chamber 32, diaphragm 40 returns under its bias to its original (FIG. 2) position to re-establish the seal between the diaphragm and shoulder 50.
  • the diaphragm may be preloaded to a position where it is just short of toggling or snapping over-center, so that a minimum initial fluid pressure is required to actuate it the rest of the way.
  • Button 124 of FIG. 6 has its central peg or pin 154 extended forwardly (outwardly) terminating in a point or conical end face 160. In the normal, nondispensing condition of the button, this point partially enters the dis charge orifice 138. While a fluid seal may be effected at this point in this manner, the main purpose of the pin pro ecting into the orifice is to assist in mechanically dislodging any incrustation, or other blocking of the orifice that might be present, through relative motion of the diaphragm and pin or successive dispensing cycles.
  • FIG. 7 a slightly ditferent swirl-forming configuration is shown.
  • the central post 144 of the orifice insert 136 is intersected by a single pair of diametrically opposed tangential slots or cuts 148 which provide lateral communication between swirl chamber 158 and the source of fluid supply once the diaphragm seal has been removed.
  • the nozzle incorporates means for mechanically cleaning the discharge orifice automatically after each dispensing cycle, such is not essential to the invention in its broader aspects as exemplified by FIGS. 1-5'.
  • the provision of mechanical break-up means or swirl chamber behind the orifice to effect a fine mist type of dispersion is not essential to the basic inventive concept, and may be omitted where other forms of liquid discharge are desired.
  • modifications of other details of construction can be incorporated without departing from the invention.
  • the securing of the orifice plate in the actuator body may be accomplished by a snap ring, or by molding a bead into the body and snapping the orifice plate beneath this bead.
  • Direct sealing by heat may also be used of course where the materials employed permit this.
  • a separate orifice plate one which is integrally formed in the body of the button may be substituted. In the latter case the abutment against which the diaphragm comes to rest would then be formed as a. separate member and inserted into the button from behind the diaphragm, using any of the means for securing it similar to those discussed for the orifice plate.
  • a spray-actuator button for fluid dispensers employing pressure to discharge a fluid product
  • said button comprising in combination a body having a socket for fluid-tight reception therein of a conduit member which serves to deliver fluid product under pressure to said body, an outlet in said body and feed passage means in said body providing communication between said outlet and socket;
  • an orifice plate positioned in and closing said outlet in said body said plate having a discharge orifice passing therethrough and located generally centrally of said outlet, and an annular flexible diaphragm portion surrounding said orifice,
  • a spray-actuator button as defined in claim 1, wherein said flexible diaphragm portion is convexo-concave with the convex face thereof making said sealing abutment with said shoulder in said body outlet in the nondispensing condition of said button.
