SPRAY HEAD FOR AN AEROSOL DISPENSER Filed Nov. 29, 1961 Wlf/l/ hi EDWARD H. GREEN by awmwdifi/zubi $10M United States Patent C) Filed Nov. 29, 1961, Ser. No. 155,731 6 Claims. (531. 239-4193) The present invention relates to aerosol dispensers and, more particularly, toa new and improved spray head for use therewith.
It is the general object of the present invention to provide a new and improved spray head for aerosol dispensers which aids nebulization or atomization of the pressurized product being dispensed therethrough.
An important object of the invention is to provide a new and improved spray head having a discharge orifice and means for imparting a swirling action to the pressurized product being dispensed as it passes through the discharge orifice whereby to aid in nebulization thereof.
A more detailed object of the present invention is to provide a new and improved spray head of the character described having a post centered in the outer end of a discharge passage extending through the spray head, a nose piece having an orifice centered therein closing the outer end of the discharge passage in the spray head and abutting against the outer end of the post, and spiral groove means formed in the outer end of the post and providing communication between the discharge passage and the spray orifice whereby to impart a swirling action to the product as it passes through the orifice.
Certain other objects of the invention will, in part, be obvious, and will in part appear hereinafter.
For a more complete understanding of the nature and scope of the invention reference may now be had to the accompanying drawings wherein:
FIG. 1 is an enlarged vertical central section taken through an aerosol dispenser spray head embodying the invention;
FIG. 2 is a further enlarged front end view looking toward the nose member of the spray head of FIG. 1;
FiG. 3 is a still further enlarged front end View of the outer end of the post of the spray head of P168. 1 and 2;
FIG. 4 is a horizontal section taken generally on the line 4-4 of FIG. 3; and
FIG. 5 is an enlarged vertical section taken generally on the line 5-5 of FIG. 1.
As illustrated in FIG. 1, a spray head It) embodying the invention is characterized by a main body portion 11 having a centrally located depending stem portion 12. A vertically disposed discharge passage 13 extends upwardly through the depending stem portion 12 and into the main body portion 11 of the spray head it The spray head 1% is adapted for use on a valved aerosol container having a -d-ispensing valve assembly of a well known type including a valve cap having an upstanding center island with an opening formed in the 00p thereof, a sealing gasket seated against the underside of the top of the center island and having a central bore aligned with the opening in the top of the center island, and a valve member normally resiliently urged upwardly into fluid-tight sealing engagement with the sealing gasket whereby to prevent the escape of ressurized product from the container. A dispensing valve assembly of this type is fully described and illustrated in FIG. 1 of :cowading application, Serial No. 18,549, filed March 30, 1960, now abandoned, by Edward H. Green. The depending stem portion 12 of the spray head 1! is adapted to be sealingly inserted downwardly through the aligned openings in the top of the center island and the sealing gasket and into an upwardly opening socket formed in the top of the valve member. When the spray head is depressed, the valve member is moved downwardly out of sealing engagement with the sealing gasket whereby to I Patented Nov. 26, 1.953
permit the pressurized product in the container to flow into the discharge passage 13 of the spray head 10 through a vertically extending slot 14 formed in the lower end of the depending stem portion '12 in a manner well known in the :art.
Referring again to FIG. 1, a horizontally disposed discharge passage 16 of substantial diameter extends between the upper end of the vertically disposed discharge passage 13 and the outer surface of the spray head 19 at the front thereof. An enlarged diameter circular recess 17 is provided in the front of the spray dispenser It in centered relationship to the outer end of the horizontally disposed discharge passage 16 for a purpose which will be evident hereinafter.
A generally cylindrical post 2t), which may be formed integrally with the spray head 10 and which may be attached at its inner end to the main body portion 11 thereof by a narrow neck 21, is centered in the horizontally disposed discharge passage 16. The post it is provided with four integral longitudinally extending external ribs 23 which are spaced equidistantly about the circumference thereof and which terminate inwardly of the outer end of the post 20. As best illustrated in FIGS. 1 and 5, the maximum outer diameter of the ribbed post 26 is substantially less than the inner diameter of the horizontally disposed discharge passage 15.
To close the outer end of the horizontally disposed dischmge passage 16, a generally cup-shaped nose piece 25 is provided. The nose piece 25 is characterized by an annular wall portion 26 having an outer diameter approximately equal to the inner diameter of the horizontally disposed discharge passage 16 and an inner diameter which is approximately equal to the maximum diameter of the ribbed post 2% and by an enlarged disc-like base portion 27 having an outer diameter slightly smaller than the diameter of the circular recess 17 formed in the front of the spray head 10. The nose piece 25 is tightly fitted in the outer end of the horizontally disposed discharge passage 16 with the base portion 27 thereof being received in the circular recess 17 formed in the front of the spray head 10, with the annular wall portion 26 being tightly fitted over the ribs 23 on the post 24 and with the inner surface of the base portion 27 abutting against the outer end of the post 20. The outer end of the horizontally disposed discharge passage 16tmay be provided with an inwardly projecting head 28 (FIG. 1) which is adapted for fluid-tight sealing engagement with the outer surface of the annular wall portion 25 of the nose piece 25. A discharge spray orifice 39 is centered in the base portion 27 of the nose piece 25. The inner end of the orifice 31 may be slightly enlarged in diameter, as illustrated in FIG. 1.
As best illustrated in FIGS. 2 and 5, the fore-going center post 2t; and nose piece 2-5 arrangement serves to separate or divide the horizontally disposed discharge passage .16 into four smaller circumferentially spaced passages 32 each of which is defined by a pair of adjacent ribs 23, the inner surface of the annular wall portion 26 of the nose piece 25, and by the non-ribbed portion of the outer surface of the center post 2%. In this fashion direct flow of fluid is permitted from discharge passage 13, to the inner end of the horizontal passagelfi, and thus, to the four circumferential passages 32. As the ribs 23 on the post 29 terminate inwardly of the outer end of the post 20, all of the passages 32 open at their outer ends into an annular space 33 (FIG. 1) defined by the outer nonrib-b'ed end of the post 24! and the adjacent inner wall portions of the nose piece 25.
Novel passage means are defined between the outer end of the post 24 and the inner surface of the base portion 27 of the nose piece 25 whereby to provide communication between the annular space 33 provided at the outer end of the post 29 and the discharge spray orifice 39. An annular V-shaped groove 35 is formed in the outer end of the post about the lon itudinal axis of the post as its center, as best illustrated in FIGS. 3 and 4, with the innermost portion of the groove 35 being in communication with the enlarged diameter inner end portion of the discharge spray orifice 34 as illustrated in FIG. 1. The annular V-sh-aped groove 35 is intersected tangentially at four locations spaced equidistantly from each other by four V-shaped grooves 37 formed in the outer end of the post 20 and having their outer ends intersecting the cylindrical surface of the post 253 at the outer edge thereof. Thus, when the spray head 16 is depressed to open the dispensing valve of the valved aerosol container, the pressurized product flows upwardly through the vertically disposed discharge passage 13, through the four horizontally disposed passages 32 into the annular space 33, and then through the four grooves 37 into the annular groove 35 and outwardly through the spray discharge orifice 30. As the grooves 37 intersect the annular groove 35 tangentially, a swirling action is imparted to the pressurized product being dispensed whereby to aid in nebulization or atomization of the product as it passes through the orifice 39, whereby the product is dispensed as a desirable fine spray,
It is noted that the annular groove 35 and the grooves 37 tangentially intersecting the groove 35 may be provided with a configuration other than \'-shaped and that, if desirable, these grooves could be formed in the inner surface of the base portion 27 of the nose piece rather than in the outer end of the post 20.
It will be understood that certain additional changes may be made in the construction or arrangement of the aerosol dispenser spray head disclosed herein without departing from the spirit and scope of the invention as defined in the appended claims.
