DISPENSING ADAPTOR FOR DISPOSABLE AEROSOL UNITS Filed Sept. 6, 1957 INVBNTOR JQYzeZ/Y gar/0w.
United States Patent DISPENSING ADAPTOR FOR DISPOSABLE AEROSOL UNITS Daniel H. Gattone, Drexel Hill, Pa., assignor to Birch & Gattone, Incorporated, a corporation of Delaware Application September 6, 1957, Serial No. 682,506 Claims. (Cl. 128-173) The present invention relates to a dispensing adaptor for use with disposable aerosol units.
Heretofore there have been many dispensing adaptors and buttons for use with valved aerosol units for soaps, detergents, insecticides and event artificial snow and the like. However, these prior dispensing adaptors and dispensing buttons have not been suitable for specialized uses, such as for administering medicaments and the like to body cavities in animals and humans, which special use requires measured dosages, nebulization and proper velocity of each dosage 'with proper control of particle sizes for use in inhalation therapy treatment and the like.
, It is an object of this invention to provide a novel dispensing adaptor for aerosol containers or pressurized units, which is highly efficient for administering the contents of aerosol or pressurized units in a manner to permit proper nebulization and discharge of medicaments for body cavity treatment and/or for inhalation therapeutic uses of solutions, powders or combinations thereof.
Another object is to provide a dispensing adaptor, formed to detachably couple direct to a valved aerosol or pressurized unit.
Still another object is to combine in a single molded unit a dispensing adaptor, a valve actuator, a nebulizer, and an outlet directing nozzle for quick-detachable and indexed connection with a disposable aerosol package.
A further object is to provide in the dispensing adaptor unit, an aerosol projection increasing means for stepping up the velocity of a calibrated metered discharge and known pressure in an aerosol unit used therewith.
A further object is to provide means in the dispensing adaptor for collecting excess medication during use.
Yet another object is to provide interchangeable nozzle means for the dispensing adaptor to provide for individual body cavity application of aerosolized medicaments and the like A further object is to provide index means adapted to position the dispensing adaptor outlet properly for discharge of the aerosol unit through the adaptors nozzle when the same is coupled to an aerosol unit for use and whereby the aerosol unit when empty is disposable and may be replaced with another unit.
With these and other objects in view, the invention consists in the construction, arrangement and combinalion of parts hereinafter described and particularly pointed out in the claims, it being understood that I do not intend to limit myself to the details of construction.
In the drawings like parts throughout the several views are given like numerals and are thus identified in the following detailed description.
Figure l is an elevational view of a suitable pressurized container with a longitudinal cross section view of the novel dispensing adaptor means in position thereon and with several special forms of tips for interchangeable use therewith;
Figure 2 is a bottom plan view of the adaptor means removed from the container;
Figure 3 is a transverse cross section view taken on 2 line 3-3 of Figure 1, disclosing the cooperating index means of the adaptor skirt and the container;
Figure 4 is a detail view of the upper portion of the container with the adaptor means removed; and
Figure 5 is a cross section view of a form of nozzle extension attachable to the nozzle shown in Figure 1.
Referring to the drawings in detail and first with respect to Figure 1, there is disclosed a pressurized container 10 with a longitudinal index key or rib 11. The container may be formed of metal, glass or plastic. These aerosol units or containers are disposable and if made of metal may be interiorly treated or coated, or if glass may be coated with suitable plastic either interiorly or exteriorly.
The top of the container is formed with the usual flange or lip to stake in the valve body 12 from which extends a hollow valve stem 13, with curved tip 14, which acts as a cam follower as hereinafter explained. The valve used may be of any standard type and of either the continuous or the metered type, such as disclosed in prior Patent 2,788,784, issued April 16, 1957, if a continuous or if metered, such as disclosed for example in the patent application Serial No. 647,352, for Means for Administering Pressurized Medicaments, Gases, Combinations Thereof and Liquids Into Body Cavities, Herbert Birch and Daniel H. Gattone, inventors.
For use with the container 10 there is provided a novel nebulizing and dispensing adaptor comprising a hollow pushed out index groove 18. This groove 18 isadapted to slidably receive the index key or rib 11 when the adaptor is placed over the valve end of the container 10.
The interior of the hollow body 15 is formed with a conical plate 19 centrally formed with an eye, at the apex thereof, such as a bushed opening 20, which slidably fits over the valve stem 13. The plate 19 from the bushed' opening 20 slopes downwardly to the sides of the body 15 above the skirt portion 17 and forms an annular trap or collection chamber to catch excess medication during repeated use of the unit.
Above the plate 19 in the Wall of body 15 is an opening 20 see Figure 1, which admits air into the body as the valve 12 is opened. This air opening increases theprojection and velocity of the dispensing means discharging from the nozzle 16 and provides more eifective and more complete nebulization of the medium in the nebulizer chamber 21 of the body 15.
The dispensing adaptor body 15 is interiorly formed with an enlargement 22, which is positioned therein, so as to be indexed with respect to the index rib 11 and groove 18, to thereby in turn position the curved combined cam and nebulizer surface 23 of the enlargement directly above the curved cam follower surface 14 of the valve stem 13. This index feature positively positions the discharge opening of the hollow valve stem toward the outlet of the tapered nozzle 16, to thereby provide maximum efficiency in action as will be apparent from the following description of operation.
As illustrated in connection with Figures 1 and 5, various forms of nozzle extensions may be used such as, the extensions 24 or 25, and may include a final small end seal cap 26 to be applied when the unit is not in use.
Operation In the operation the user first takes a ready prepared pressurized container 10 and inserts the head thereof with the valve stem 13 into the adaptor means skirt portion 17, so that index key or rib 11 slides into the skirt index groove 18.
Then the user decaps the nozzle to be used and, for
example, holding the unit between thumb and forefinger directs the same'toward the cavity, or he may insert same in the cavity, to be treated and thus presses downward upon the. exterior top surface of the enlargement 22. suchdownwardpressure causes 'the combined nebulizer and cam surface 23 to cam or engagewith the curved end 14 of the hollowvalve' stem 13; thereby opening the valve 12 and discharging pressurized'medium against the surface 23 into the'nebulizer chamber 21 from where it is projected through the nozzle 16 with the assistance of the airdrawninto the chamber 21' through opening 20 intothe cavity treated.
Obviously,'any medicament may be discharged from the.container"10, such medicament may be all liquid or a combination of liquid and micronized powderedantibiotics' or a liquid with a gas or combination of gases, asprescribed; Obviously the propellant used depends upon the nature of the medicament.
Thus there is provided a self-nebulizing dispensing adaptor for aerosol throw away units, which are filled with mediums, such as liquid medicaments, or the like, which may be either for ethical or over the counter commercial distribution.
Although only one embodiment of the invention has been illustrated and described in detail, it is to be expressly understood that the invention is not limited thereto. Various changes may be made in the design and arrangement without departing from the spirit and scope of the invention, as will now likely occur to others skilled in the art. For a definition of the limits of the invention, reference should be had to the appended claims.
