Definitions

  • Aerosol materials comprise mixtures of an active ingredient or product and a propellant medium.
  • the product propellant are mutually soluble such that dissolved liquid propellant is present in the emerging stream.
  • the dissolved propellant readily evolves as vapor from the stream upon exposure of the stream to the comparatively low pressure of the atmosphere.
  • the rapid evolution of vapor from the product causes the stream to disintegrate into a spray of fine droplets.
  • a simple orifice will produce adequate sprays.
  • the product and propellant components are not mutually soluble.
  • aqueous products are not mutually soluble with the popular chlorinated-fluorinated hydrocarbon propellants. In such soluble systems, the product stream contains little or no propellant in a liquid state.
  • FlG. I is an elevational view in cross-section of a pressurized dispenser with an aerosol actuator dispensing cap including the mechanical break-up nozzle insert of the present invention
  • FIG. 2 is a perspective view of the pin and cap components of the mechanical break-up nonle of the present invention in disassembled form;
  • FIG. 3 is an elevational view in section of the cap and the pin portions assembled to form a mechanical break-up noule insert means
  • FIG. 4 is an elevational view of the pin component taken from the plane 4-4 of FIG. 6;
  • FIG. 5 is an elevational view in section of the pin component taken along the plane 5-5 of FIG. 6;
  • FIG. 6 is a top view of the pin component portion
  • FIG. 7 shows the nozzle assembly installed in a dispenser actuator similar to that of FIG. 1 except that the entire nozzle assembly including the cap component is received within the dispensing passage.
  • the mechanical break-up nozzle assembly of the present invention is constituted by the assembly ofstem or pin member 10 and cap member 26. This assembly is frictionally retained in the dispensing passage 7 of a valve actuating dispenser cap 1.
  • the actuator cap 1 is snap fitted and frictionally retained on a rolled seam which is conventionally employed to secure a valve counting cup 4 in the mouth of an aerosol pressure container C.
  • the container C contains a product P under pressure provided by a conventional chlorinated-fluorinated hydrocarbon propellant. The product and propellant may or may not be mutually soluble.
  • a valve 5 controls release of the pressurized product P from the container C.
  • a product eduction or dip tube D is employed to convey product from the bottom of the container to the valve.
  • valve 5 is surmounted by a hollow valve stem 6 which fits within a valve stem receiving socket 13 on the underside of actuator cap 1.
  • the valve stem receiving socket I3 is in communication with the product passage 7 of the cap.
  • the valve is actuated by downward finger force on hinged tab of portion 9 of the cap 1.
  • the valve 5 is opened to provide a path for product P under pressure which path extends through the valve 5, the valve stem 6 and product passage 7 to the mechanical break up insert assembly pin member 10 and thence through that member to be emitted as a spray of fine droplets through outlet orifice 32 of the cap member 26 of the insert assembly.
  • FIG. 2 shows mechanical break-up insert assembly of the present invention prior to assembly of the cap member 26 on the pin member I0 and FIG. 3 shows the assembly.
  • Pin member I0 includes an axial passageway 12 for How of product.
  • Axial passage 12 terminates in a pair of diametrically opposed lateral apertures 16 and I8.
  • Aperture: I6 and I8 communicate with axial grooves or slots 20 and 22 which are arranged to provide feed paths tangential to an axial swirl chamber 36.
  • Cap member 26 includes an interior bore 30 into which the upper portion of the pin member 10 is received.
  • a discharge orifice 32 extends through the end wall of the cap member to communicate with the swirl chamber 36.
  • An annular collar 24 integral with pin member 10 is received in an annular recess 28 in the cap member 26 to assist in securing the cap member on the stem member.
  • a clearance 34 exists above the upper surface of the annular collar 24 to allow for flush seating of the upper end surface of the pin 10 against the inner surface of the end wall of the cap member 26. This insures that all of the product will flow through the tangential feed portions of grooves 20 and 22 to enter the swirl chamber 36 tangentially.
  • FIGS. 3 through 6 the flow of product through the assembly of pin member 10 and cap member 26 is indicated by arrows.
  • the product traverses the axial passage 12 of the pin member 10 to emerge through transverse apertures I6 and 18.
  • the axial passage 12 is terminated by an end wall 14 which is a part of the pin member.
  • the bore 30 of cap member 26 cooperates with the upper portion of pin member 10 to form with axial slots 20 and 22 of the pin member a pair of axial passageways in communication with apertures I6 and 18.
  • Product traversing these apertures travels axially through the passage formed by slots 20 and 22 and then is directly radially inward along the upper surface of pin member end wall 14.
  • the portion of slots 20 and 22 through which this radial product flow occurs are tangential to a central axial swirl chamber 36.
  • FIG. 6 is an end view of the top of pin member I0 and shows the tangential disposition of the upper portion of slots 20 and 22 and shows by arrows how product flowing through these slots has imparted to it a circular swirling motion as the product enters the swirl chamber 36.
  • Discharge orifice 32 in cap member 26 is co-axial with swirl chamber 36 of pin member I0 and in communication therewith.
  • Product emerging from the discharge orifice 32 retains the swirling motion imparted to it by the tangential feeds and swirl chamber.
  • the emergent swirling product centrifugally radiates as a conical spray of fine droplets.
  • FIG. 7 illustrates the application of mechanical breakup insert assembly of the present invention to conventional dispenser cap having a large diameter discharge passage 7.
  • dispenser caps are common for dispensing foam products.
  • the exterior diameter of the cap portion 26 of the insert assembly is sized to permit the admission and frictional retention of the insert assembly in the discharge passage 7. This is an alternative manner of application to that shown in FIG. I wherein only the stem portion 10 is received and frictionally retained in the discharge passage.
  • the present invention provides a mechanical spray breakup means which can be adapted to be fitted to a wide variety of standard dispensing buttons, caps and actuators. It provides a simple economical means for converting many existing caps to provide for mechanical break-up of the product. It permits the conversion of existing caps intended for dispensing viscous or foam products into caps suited for spray dispensing. Both of the pieces which constitute the insert assembly are easily molded from conventional plastic using dies having minimal complexity.
  • valve actuator for a pressurized aerosol dispenser, the valve actuator having a discharge passage, a mechanical nebulization noule assembly insert positioned in the discharge passage, said nebulization nozzle assembly insert including a hollow pin member of molded plastic dimensioned to be received in the discharge passage and a cap member of molded plastic fitted over the outer end of the pin member.
  • the cap member including an axial discharge orifice
  • the pin member including a central axial product passage terminated by a transverse wall near the outer end of the pin member, the outer face of said wall having formed thereon a central swirl chamber depression and feed grooves tangential to said swirl chamber, the central axial product passage being in communication with the radial extremities of the feed grooves, said cap member being in the form of an inverted cup with the discharge orifice in the end wall of the cap and coaxial with the swirl chamber, the cap interior surface cooperating with the feed grooves and swirl chamber depression to form a discrete chamber and passages.
  • cap member is adapted to be frictionally retained in the discharge passage of the valve actuator such that substantially all of the insert assembly is interior of said discharge passage.
