Definitions

  • a micro-emitter for pressure packages comprises an apertured member disposed across the nozzle opening 52 us. c1. 222/189, 222/402.14 through which a fluid Product in the P Package 151 1 Int. Cl B65d 83/14 is eXPellmi
  • the apertured member has at least one p- [58] Field of Search 222/189, 402.14; mm which is from l0 l5 1 diameter- In one 239/575, 5903 stance, propellant pressure is used to force the fluid through the aperture and break it into small drops.
  • the present invention relates to aerosol containers and more particularly to a device for controlling discharge of a fluid product from a pressure package.
  • US. Pat. No. 2,826,453 relates to a seeper valve assembly utilizing a filter material pad in conjunction with a pressure package.
  • the filter material in this case, absorbs the liquid in the package and evaporates the liquid into the atmosphere.
  • the product therefore, goes from a liquid to a vapor state on the surface of the filter.
  • the product to be discharged must have a high vapor pressure to evaporate, e.g., perfume. If the product has a low vapor pressure, it would simply pool on the surface of the filter. Moreover, any nonvolatile solids dissolved in the product would tend to leave a crust on the filter. Accordingly, the device is severely limited as to products which may be used therewith.
  • a microemitter which controls the flow of the fluid from the pressure package and influences the size of the drops exiting therefrom.
  • the term microemitter designates the device of the present invention which controls and influences the discharge of a fluid product from a pressurized package. The above is accomplished by positioning an apertured substrate upstream from the exit orifice of an aerosol container.
  • the apertured member may be filter or membrane material depending on the desired particle size of the expelled product.
  • polycarbonate, glass, sintered silver, sintered stainless steel, sintered high density polyethylene, cellulose acetate, cellulose nitrate, etched stainless steel, etched copper and electrodeposited nickel, tin-lead alloy, rhodium, gold, copper, silver or iron are appropriate.
  • the particle size is controlled from very small drops, e.g., less than 5 p. to large drops in the order of 30 p. simply by changing the diameter of the aperture in the substrate.
  • the flow rate through the aperture is influenced by pressure; viscosity, density and aperture diameter, tortuosity and length and the surface properties of the substrate.
  • the filter or membrane of the present invention does not serve its usual known function, i.e., to remove or separate different sized material from a fluid stream or to absorb and permit evaporation of a fluid.
  • the aperture or apertures in the filter or membrane serve to control the flow of the fluid and to assist drop formation.
  • the present invention operates on the principle ofatomization.
  • the principle is discussed in a publication by W. R. Marshall Jr., Atomization and Spray Drying, Chemical Engineering Progress Monograph Series No. 2, 50, 1950, published by the American Institute of Chemical Engineers.
  • atomization is accomplished either hydraulically or pneumatically.
  • the pressure exerted on the fluid by the propellant forces the fluid from the apertures and breaks the fluid into small drops such as like a garden hose.
  • a high velocity vapor stream is used to assist the break-up of the fluid.
  • the vapor stream is preferably derived from the propellant in the pressure package and impacts the fluid either before or after the aperture and breaks it into small drops.
  • the vapor should come from a second liquid layer.
  • the propellant should be largely concentrated in one of two liquid layers.
  • the number thereof may also be controlled to give a desired discharge.
  • the number of apertures may vary from 1 aperture to 3 X 10" apertures depending on the specific application.
  • the present invention may be constructed integrally as a complete valve assembly or it may be constructed separately as a "top hat which is readily affixed to the valve stem of a standard aerosol valve.
  • FIG. 1 is an elevational view of a pressure package provided with a micro-emitter of the present invention

  • FIGS. l1-16 are enlarged vertical cross-sectional views of alternate embodiments of pneumatic type micro-emitters of the present invention.
  • FIG. 1 there is shown a typical pressurized aerosol container 10 well known in the art.
  • the container is normally filled with a fluid product (not shown) which is to be discharged by opening a valve.
  • Discharge pressure is obtained by a propellant which may be mixed with a product in a single or dual liquid phase system, or may be physically separated from the product in any well known manner.
  • a dip tube 12 and standard valve assembly 14 depend from the top of the container 10 and are mounted thereto by means of a cap 16.
  • the micro-emitter is adaptable to a standard depress actuated aerosol valve and comprises a top hat l8 and locking device generally indicated by the numeral 20.
  • the conventional valve is of the type wherein downward pressure exerted on the valve stem 22 opens the valve (not shown) to allow the discharge of the fluid product.
  • a pre-filter 24 Secured between the dip tube 12 and the valve body 14 is a pre-filter 24 through which the product is filtered prior to entering the valve body.
  • the prefilter material may be any well known filtering material which will separate solid particles which would tend to clog the valve parts.
  • top hat 18 Positioned on top of the valve stem 22 is a top hat 18 including a micro-emitter of the invention.
  • the top hat 18 may be constructed of any suitable material and plastic is preferred.
  • the top hat 18 is constructed so that its base will readily slide over the top of the valve stem and give a secure fit. Since valve stems are generally tubular, the top hat would also be tubular with an inside diameter approximately the same as the outside diameter of the valve stem.
  • the top hat upwardly terminates in an exit orifice 26; andbetween the orifice 26 and top of the valve stem there is mounted an apertured member 28, seal 30, filter 32 and seal 34 in descending order.
  • the apertured member 28 may be selected from any of the aforementioned materials depending on the number and size of apertures needed for the desired product and result.
  • the apertured member 28 is preferably in the form of a thin sheet tightly secured between lip 36 and a first annular seal 30.
  • the seal 30 may be any material which would not be degraded by the product or propellant; and flat rubber gaskets or plastic washers are preferred.
  • a second filter 32 is secured immediately preceding the apertured member 28 in relation to fluid flow. As is shown in the drawings a filter sheet 32 is securely positioned between the first seal 30 and a second similar seal 34. In general, any filtering material which has the ability to remove material larger than the diameter of the apertures would be appropriate.
  • the second seal 34 also serves to provide a seal between the top hat and the top of the valve stem 22 to ensure that no fluid can leak therebetween.
  • the top hat also has an exterior annular flange 40 which is preferably moulded integrally therewith.
  • the flange 40 coaets with an on-off feature, more fully described hereinafter, to actuate the valve.
  • the on-ofl' feature or locking device 20 allows the operator to use the pressure package when he desires for the length of time that he desires. It is constructed so that it may be readily affixed to a standard valve cap 16. It comprises a cylinder shaped upstanding member 42 having exterior threads 44, an interior annular flange 46 positioned upwardly of the bottom of the cylinder and detent means such as annular bead 48 disposed inwardly at the bottom edge of the cylinder. The annular flange 46 engages the top of the valve cap 16 and the detent means 48 engages the lower lip of the valve cap 16 so that the cylinder 42 may be snapped onto the cap 16 and securely held thereto.
  • Rotatably threaded onto the upstanding cylinder 42 is a cap 50 having a concave top 52.
  • a central orifice 54 in the concave top 52 permits the top hat 18 to extend therethrough; and the edge of the orifice defines a shoulder 56 engageable with the annular flange 40 of the top hat 18.
  • the shoulder 56 engages the annular flange 40 and depresses the top hat 18 and valve stem 22 to open the valve.
  • the valve may then be left open for as long as needed and may thereafter be closed by simply unscrewing the locking cap 50 to release the pressure on the valve stem 22 to close the valve 14. It is to be noted that the continuous dispensing of the pressurized product is maintained as long as the locking cap is screwed downwardly as is shown in FIG. 3.
  • the top hat 18 includes an apertured sheet 28 having a plurality of apertures 58, although it will be understood that a single aperture could be used. Among other names for the apertures 58 would be micro-orifice, pore or pin hole.
  • the valve is opened, the product fluid is forced up the dip tube 12 by the propellant, through a pre-filter 24 and through the depress type valve 14. The fluid product then is forced through the filter sheet 32 and then through the apertures 58 in the apertured sheet 28. As the fluid is forced out of the apertures 58, it is broken into small drops and expelled into the surrounding air as shown by the arrows.
  • FIG. I 5 An alternative top hat construction is shown in FIG. I 5.
  • an interior shoulder 60 is formed to abut the top of a valve stem upon which the top hat is placed.
