Definitions

  • the Closure [58] Field of Search ..222/402.1, 402.1 1, 402.12, member is responsive to the movement of the actuator and is ZZZ/40113, 402,14 displaceable thereby between open and closed positions and, for the sake of safety, also an intermediate temporary position [56] References Cited impact abutment.
  • the invention relates generally to pressurized fluid containers such as aerosol cans and more particularly to improved actuating means for the valve stem thereof.
  • aerosol can refers to those containers having a pressurized fluid that is used to dispense the contents of the container.
  • the prior art provides a valve stem extending upwardly from the container.
  • An actuator is used to engage and axially depress or otherwise displace the stem in order to open the valve.
  • the actuator includes a passageway fluidly communicating with the valve stem and terminating in a nozzle or suitabledispensing orifice. When the actuator is depressed, the contents of the container flow first through the valve stem, then through the passageway and are discharged from the nozzle.
  • Still another disadvantage of the prior art is that generally no means are provided for positively indicating the dispensing direction of the nozzle. Frequently, because the user is not careful, or is not aware that the nozzle is not properly pointed, the contents may completely miss the intended target. This is, of course, both messy and wasteful. Further criticism of the prior art construction is that frequently the top of the can did not readily lend itself to price marking while the cans were still in the shipping carton. Thus additional handling was required at increased costs. It has also been found that the shape of the top of many examples of the prior art did not permit safe stacking. Finally, it has also been found that much of the prior art required greater effort to actuate the valve stem than does the present invention.
  • the present invention provides a lever or actuator or actuator lever for an aerosol can valve stem as well as a closure member that responds to the movement of the actuator lever. That is, when one portion of the actuator is depressed, the nozzle is raised into an operative position and the closure member that initially covered the nozzle in the nonoperative position is also depressed and thus uncovers the nozzle.
  • the actuator and the closure member cooperate with each other to provide automatic exposure of the nozzle when the aerosol can is in use. Further the actuator and the closure automatically cooperate with each other to protect the nozzles dispensing orifice from contaminants when the aerosol can is not in use.
  • the actuator lever is floatingly" supported in the cap or base or base member that is snapped on to the aerosol can.
  • One portion of the actuator lever is resiliently supported by the nozzle closure member.
  • Another portion of the actuator lever includes laterally extending tabs that are guided in and retained by inverted, openended slots formed in the base member.
  • the actuator lever is displaced angularly about integral pivots that project into another pair of inverted, openended slots in the base member while in another embodiment the angular movement of the actuator lever is about laterally extending lugs that mate with similarly shaped, inverted and open-ended slots in the base member.
  • Each lug has a surface that acts as a fulcrum and, in effect, provides a camlike action.
  • both embodiments allows the actuator lever to float" in the slots of the base memberv Means are also provided in the present invention to prohibit the casual or unauthorized tampering with the actuator lever.
  • a tab is formed integrally with the actuator lever and cooperates with a portion of the base that is mounted on the can to prevent the actuator lever from being depressed. The tab may easily be lifted up and snapped off by the purchaser prior to the first usage of the aerosol can. The actuator lever can then be depressed in the usual manner, there being sufficient clearance, for the tilting of the actuator lever, between the lever and the base once the tab is removed.
  • the present invention also overcomes other deficiencies of the prior art mentioned above.
  • the actuator lever is formed with converging sidewalls whereby the lever is narrowest at the end thereof which contains the nozzle. This construction provides for an inherent indication of nozzle and spray direction.
  • the substantially flat top surface of the base is flush with the planar, upper surface of the actuator lever thus permitting price marking of the cans while they are still in the shipping container.
  • the flat, substantially continuous surface of the combined lever and base allows safe stacking of the aerosol cans.
  • lt is yet another object of the invention to provide means prohibiting unauthorized or accidental movement ofi the actuator lever.

  • An edge 52a of the body portion 52, the side portions 50 and the base leg 46 define an opening 54.
  • a notch 56 is formed in each of the side edges of the body portion 52 such that they cooperate with the inwardly projecting tabs 34 of the walls 26 and function in a manner to be described later.
  • the plate 14 is molded with, or otherwise formed and assembled to, the base 12 with a suitable clearance between the converging sides of the plate 14 and the walls 26 which converge at substantially the same angle. Clearance is also provided between the respective notches 56 and the tabs 34.

It will be appreciated that the offset portion 84 between the extension 82 and the face 80 is positioned over the edge 86 of the skirt and thus will prevent the downward movement of the end 66 of the actuator 16. Thus the aerosol can cannot accidentally be used.
  • the first authorized user must lift up and break off the tab 82 including the offset portion 84 before the actuator can be depressed. This construction will prevent the casual user from sampling and thus depleting the contents.

  • This construction provides for angular displacement of the actuator 16 about the axis of the cylindrical members 70.
  • the present invention is not limited to this precise construction and may, in fact, take the form shown in FIG. 9. With the exception of the fulcrum arrangement to be described hereinafter, the remainder of the components are the same as in the first embodiment and will not be described again.

  • both the top surface of the extensions 90 and the mating edges of the recess 92 can both be arched. Regardless of which combination is selected the extensions perform as a fulcrum for the actuator lever 16. The lever then moves angularly about the fulcrum with the extensions 90 providing, with the recesses 92, a cam action.
  • the inherent resiliency of the plastic material is utilized to permit the actuator 16 to be introduced into the channel 24 formed on the top of the base 12. It should be noted that when assembled the tabs 68 at the wider end of the actuator 16 are positioned in the recesses 30 at the wider end of the channel 24 and the lateral extensions or fulcrums 70 or 90, respectively, about which the actuator 16 moves, are in their mating recesses 32 or 92, respectively. Also, the inwardly extending projections 34 at the narrow end of the channel are positioned in the notches 56 at the side edges of the resilient plate 14.

  • the actuator 16 may then be depressed at the wider end 66, with the narrow end 68 pointed at the target.
  • FIGS. 4 and 5 it will be seen that as the right hand or wider end of the actuator 16 moves downward and in a clockwise direction about the pivot or fulcrum, the boss 72 on the underside of the actuator 16 seats itself on the aerosol valve stem V. Further movement in this direction will axially depress or otherwise displace the valve stem V.
  • the dispensing nozzle 78 of the actuator is thereby placed in communication with the interior of the container.
  • the resilient plate 14 will move in a counterclockwise direction from the nonoperative position shown in FIG. 4 where the nozzle cover 58 is in front of the dispensing nozzle 78 and the body portion 52 of the plate 14 is in surface-to-surface contact with the underside of the actuator.

  • the opposite angular movements of the actuator lever 16 and the plate 14 occur substantially simultaneously and, in the embodiments illustrated, the movement of the valve stem V occurs only slightly thereafter.
  • the scope of this invention also includes the seating of the boss 72 directly on the valve stem, even in the nonoperative or rest position. It will be evident that, due to the resiliency of the plate 14, a release of the finger pressure on the wide end 66 of the actuator lever 16 will allow the plate 14 to return from the operative position of FIG. 5 to the nonoperative or rest position of FIG. 4.
  • the actuator lever 16 moves angularly about a pivot axis, while in the other embodiment illustrated (FIG. 9), a fulcrum arrangement provides a camlike angular motion for the actuator lever 16.
  • the actuator 16 is floatingly supported by the resilient plate 14 because the fore-and-aft lateral extensions 68, 70, of the actuator lever 16 are contained in elongated, open-ended slots 30, 32, 92.
