No. 288,665 14 Claims. (Cl. 222-182) This invention is a combined cap and valve operating member for aerosol dispensers of the type which is adapted to be permanently mounted on the top of an aerosol can and embodies a valve operating member, hereinafter referred to as the valve operator, cooperating with a valve stem so that, when manually actuated, the valve of the can is opened and material discharged therefrom. With the valve operator is associated a cap or hood which protects the valve operator against inadvertent actuation during stacking or otherwise. This broad combination is well known, but in every case, so far as I-am aware, the discharge of the spray therefrom is always in the same direction relative to the axis of the can.
The primary object of the present invention is to provide an assembly of the character described wherein the direction of the spray may be varied relative to the axis :of the can in a simple and efficient manner, at the will of the user.
Speaking generally, the valve operator is in the form of a tab provided on its underside with a socket to receive the valve stem of an aerosol can. This tab is integral with and pivotal with respect to the cap which surrounds the tab and a discharge passage leads from said socket to an arcuate surface on the cap. A spray director of arcuate form is seated with respect to the arcuate surface on the cap and is provided therein with grooves communicating with a discharge outlet to the atmosphere. This spray director is manually adjustable, so that the discharge outlet thereof may be adjusted by circumferential movement of the spray director to direct the spray in different angular relations to the axis of the can, whereby the can may be held substantially upright at all times, while directing the spray in different angular directions relative to the horizontal.
Features of the invention, other than those adverted to, will be apparent from the hereinafter detailed description and appended claims, when read in conjunction with the accompanying drawings.
The accompanying drawings illustrate different practical embodiments of the invention, but the constructions shown therein are to be understood as illustrative, only, and not as defining the limits of the invention.
FIG. 1 is a perspective view showing one form of the combined cap and valve operating member of this invention.
FIG. 2 is a central vertical section through the structure of FIG. 1.
FIG. 3 is a top plan view of such structure with the spray director removed.
FIG. 4 is a fragmental view looking from the left side of FIG. 3, as indicated by the arrows, 4, 4 in the latter figure.
FIG. 5 is a side elevation, partly in section, of the spray 3,169,673 Ce Patented Feb. 16, 1965 Referring to the drawings, 1 indicates a valve operating member shown as a pivoted tab provided on its under side with a socket 2, adapted to fit over the tubular valve stem of an aerosol dispenser can. The tab is pivoted at 3 to the top wall 4 of a cap by a relatively narrow in tegral strip, while the remainder of its periphery is spaced from said top wall, as shown best in FIG. 1.
The cap is shown as provided with an inner wall 5 having at its lower end an internal bead to'engage with the curled edge of the mounting cup of the can for the purpose of firmly supporting the cap thereon. Spaced from the inner wall 5 is an outer wall 6 of any desired height, having at one side thereof an external recess 7 in which is formed a substantially semi-cylindrical boss 8 having an exposed cylindrical bearing surface 9 at the opposite sides of which are formed slots 10. Cooperating with this bearing surface 9 is a spray director 12. This spray director is of arcuate form and it is provided at its opposite lateral edges with flanges 13 which extend into the slots 10 and carry at their outer sides horizontally alined trunnions 14 received in horizontally alined indentations 15 formed in the opposing faces of the slots 10.
The inner surface of the spray director 12 is of arcuate form, corresponding to the bearing surface 9 of the boss 8 and the trunnions 14 and indentations 15 are located at the center of curvature of the arcuate surfaces of the boss and spray director so as to maintain the concave surface of the latter at all times in close facial bearing engagement with the bearing surface 9 of said boss, as best shown in FIG. 2. With this arrangement the spray director is supported for pivotal movement about the axis of the trunnions while maintaining the facial relation referred to.
The socket 2 at the under side of the tab 1 is connected to a discharge passage 16 which leads to the bearing surface 9 of the boss 8 and communicates with grooves 17 so that material fed from the can through the passage 16 enters into said grooves 17. These grooves are adapted to communicate with registering grooves 18 formed in the inner arcuate face of the spray director 12 and said grooves 18 lead to an annular chamber 19. Passages 21) lead from the annular chamber 19 to discharge outlet 21 and are tangent to said outlet so that material fed from the can through the passage 16 and grooves 17 and 18 into the annular chamber 19 are discharged from the discharge outlet 21 in the form of a whirling spray.
This whirling spray means is the preferred form of this invention, although, if desired, the chamber 19 may be substantially cylindrical and devoid of the tangential passages 20, so as to produce the usual conventional spray without the swirling action therein.
The grooves 17 and 18 of the boss and spray director respectively are made sufliciently long so that they will communicate with one another as the spray director is pivotally moved on the trunnions 14, so that the discharge outlet 21 will preferably be at all times in communication with the passage 16 and the socket 2, although, if desired, the spray director may have sufiicient overtravel to actually bring these grooves out of registration and thereby seal the discharge passage 16 with respect to the atmosphere. This is optional.
When the structure of this invention is mounted on an aerosol dispenser can C, it will be apparent that the direction of the spray pattern can be vertically adjusted relative to the axis of the can and cap by merely manually shifting the spray director 12 circumferentially of the boss 3. To facilitate this operation, the upper surface of said spray director may be knurled or serrated, as indicated at 22.
The top wall 4 of the cap is shown as concave, but it may be of any other shape without departing from this invention although in practice it is preferred that the uppermost edge or surface of this top wall 4 be at a higher elevation than both the valve operating tab 1 the highest point of the spray director 12, so that a plurality of cans equipped with this invention may be stacked without actuating or bearing upon either of these parts.
In the cap as shown in FIGS. l6, the spray director is of arcuate form and cooperates with a boss having a convex outer bearing surface. In the structure of FlGS. 7-9, the spray director is in the form of a cylindrical body 23 which is received within a socket 24 in the cap. The concave surface of this socket may have direct hearing with the convex surface of the spray director but, in practice, it is preferred to form on the surface of the socket 24 parallel sealing ribs 25 which bear against the convex surface of the spray director and form therewith seals against leakage of material between the spray director and the socket.
The parts described are preferably injection moldings of plastic which is more or less resilient and the socket is preferably initially molded so that it has a'slightly less radial dimension than the diameter of the spray director 23. When the spray director is forced into this socket, it slightly expands the socket radially to thereby insure firm resilient radial engagement between the sealing ribs 25 and the spray director. The spray director may be held in place solely by its partial enclosure within the socket, but, in practice, it is preferably positively held in place by alined trunnions 26 at its opposite parallel ends which project into bearing cavities formed in the cap.
The spray director has a diametric passage 27, the inner end of which is at all times in communication with one of the grooves 28 formed in the base of the socket 24 and communicating with a discharge passage 29 which corresponds to the passage 15. The outer end of the passage 1 7 communicates with a chamber 39, from which passages 31 lead to a discharge outlet 32 formed in an outlet nozzle 33. This nozzle 33 may be used in he of the discharge outlet arrangement of FIGS. 1-6, although the latter construction may be employed instead of a separate nozzle. When a separate nozzle is used, it is adapted to be sprung into an opening in the spray director and held in place therein by a flange 34, as shown in F116. 7. The exposed surface of the nozzle is knurled or serrated as at 34 to facilitate pivotable adjustment of the spray director.
Thus, the main difference between the structures of FIGS. 7, 8 and 9 and that of the preceding figures is that the spray director is received in a socket in the cap, whereas in FlGS. 16, the spray director fits over a boss formed on the exterior of said cap.
The foregoing detailed description sets forth the invention in its preferred practical forms, but the invention is to be understood as fully commensurate with the appended claims. 7
