Application August 22, 1951, Serial No. 243,153

13 Claims. (Cl. 299-825) The present invention relates to a spraying device including a valve controlled outlet. More particularly a spraying device having a pressurized supply of a substance to be sprayed or atomized.

The present invention specifically relates to a deodorizing or atomizing device that is actuated in consequence of the opening and closing movements of a door.

More particularly, the invention is an improvement over the arrangements disclosed in my prior Patents 2,534,464 and 2,534,465 patented December 19, 1950.

The present invention specifically relates to the actuation of the valve embodied with the container having the deodorant or other material therein that is to be disseminated into an enclosed space such as a room or cupboard.

This invention additionally relates to an attachment for a conventional aerosol type dispenser including a valve actuator for the control valve of such dispenser.

Accordingly the invention has for an object to provide in a deodorizing device of the type referred to above a valve actuator including an element embodied with the supporting structure for the container and additional means embodied with the container for cooperation with said first mentioned element to effect movement of the control valve to permit an atomized discharge of the contents of the container.

The invention has for an additional object to provide a compact valve actuator embodied with the deodorant container including a biased lever swingably mounted with respect to a reciprocable plunger to reciprocate this plunger and which lever is so constructed and arranged that the biasing means therefore maintains the lever in position to be actuated by a reciprocating member which reciprocates responsive to the opening and closing movement of a door.

It is an additional object of the present invention to provide a cam type valve actuator for the control valve of an aerosol type dispensing container.

In connection with the present invention the same is applicable to those aerosol type containers of the type similar to the disclosure of prior patents Rotheim 1,892,750 and Mobley 1,614,532. Additionally, my prior Patent 2,534,465 discloses an operative control valve arrangement for an aerosol type dispenser.

Further and more specific objects will be apparent with reference to the accompanying drawings in which Figure l is a front elevational view of the invention as embodied with a supporting means and applied to a door;

Figure 2 is a partial plan and partial sectional view on an enlarged scale taken along line 2-2 of Figure 1;

Figure 3 is a partial view similar to Figure 2 with the door shown in open position;

Figure 4 is an enlarged view of the valve actuator means embodied with the container and including a modified biasing means;

Figure 5 is a sectional view of a modification of the arrangement shown in Figure 4;

"ice

Figure 6 is a view similar to Figure 5 and showing the cam lever in a different position; and

Figures 7 and 8 are modifications of the biasing means for the cam lever.

In connection with Figure 1, a supporting means denoted generally by 1 is mounted on the exterior of a door 2 and includes the resilient clamping arms 3 which retain an aerosol type container 4 within the supporting means or housing 1. In connection with the housing, the same is illustrated as being open on one side although it is readily appreciated that a suitable closure having an aperture therein can be embodied with the arrangement disclosed. The aperture will be in alignment with the discharge orifice in the atomizing nozzle of the container 4. The particular type of housing or supporting means for the container shown is merely illustrative and side walls can be eliminated since as far as the operability of'the device is concerned it is, of course, evident that there must be a rear wall or portion 6 that can be secured to a door 2, at least a portion of a bottom wall 8 for supporting the base of the container and a top wall portion 9 including a depending outer flange 10 to support and house the part of the valve actuating means that reciprocates in a common plane responsive to opening and closing movements of the door. The top of the extension of the neck or upper portion of the container denoted generally at 7 is slotted to receive a cam lever 11 pivotally mounted about an axis provided by a pintle or pin 12 transversely disposed with respect to the extension 7.

Biasing means for the cam lever 11 are provided which can be of dilferent form as hereinafter set forth but which must have the resilient characteristics referred to hereinafter. In the drawings, particularly Figures 1 to 3, one form of biasing means is the spring member 13 which at its upper and lower end is bifurcated to fit in notches provided respectively in the pin 12 and the cam lever 11. The spring member 13 can have integral bi furcated ends or have the ends attached thereto in any suitable fashion. A modification of the biasing means is illustrated in Figure 4 in which a spring wire 13 passes through slots provided respectively through the pin 12 and the cam lever 11. The free ends of the spring wire are flattened and bent as indicated at 13a and 13b to prevent withdrawal from the slots. To provide the proper spring action the area of the wire that is within the slots is also flattened. The flattening of the spring wire provides the purchase to eifect the resilient swinging movement of the cam lever 11 about the pin 12.

As denoted in the drawings the door frame, indicated generally at 15, includes the stop member 16 against which the door abuts in closed condition. As is apparent from Figure 2 the supporting means 1 is provided with a slot 17 in the rear wall 6 through which projects an actuating member 18 which includes a downturned end portion 19, the member 18 crosses the top of the door so that when the door closes, the end 19 abuts the door stop 16 thereby reciprocating the actuating member in one direction. Within the casing or embodied with the supporting structure is a rod 20 slidably receiving an inverted U-shaped bracket member 21 having apertured legs 22 and 23 and embodied with the base of this bracket member 21 is an apertured striker element or depending plate portion 24 that contacts the lever 11 responsive to the reciprocating movement of the actuating member 18. The bracket member 21 is secured to the member 18 and moves with the same. A spring 25 is biased between the depending end 22 of the bracket 21 and the front wall or flange 10 of the supporting member. It is clearly seen, therefore, that as the door moves from the position shown in Figure 2 to the position shown in Figure 3 the spring 25 which has been compressed expands and reciprocates the actuating memberlS outwardly ofthe housing so that the down-turned end 19 thereof moves outwardly from the door toward the frame thereby eifecting reciprocable movement of the plate portion 24 in an opposite direction to engage the lever 11 to pivot the same to actuate the valve of thecontainer 4 to effect an atomized discharge through the discharge orifice 26, Figure 4, of the container nozzle. As shown the supporting means for the actuating member are mounted to project slightly above the upper edge of the door since there is usually a slight space between the upper edge of the door and the adjacent face of the door jam'or frame. However, in the event of a close fitting door the upper face of the door can be recessed to accommodate the reciprocating actuating member 18.

It is to be pointed out that the arrangement is operative if the device is mounted on a shelf or bracket and the door moves relative to the down-turned end 19 of the actuating member so that the door will engage this end to compress the springs 25 in a manner similar to the arrangement shown in Figures 2 and 3.

Referring now to the specific movement of the parts to efiect a discharge, and as indicated in Figures 4 to 6, the extension member 7 has a slot 27 extending therethrough transverse to the pintle 12. The lever 11 rotatable on the pintle 12 moves in this slot and the lower end of this lever contacts the upper end 28 of a plunger indicated by dotted lines in Figure 4 referring to one type of plunger for an aerosol container, or the upper end 28 of another type shown in Figures and 6. In connection with Figure 4, one type of aerosol bomb presently commercially available includes a hollow reciprocable stem 29 and the lower end of this stem actuates a valve to permit fluid that is under pressure in the container to flow under the stem and out of the discharge orifice 26 when the stem is pushed toward the container proper. in Figure 4 the cylindrical push button type element 28 surrounds this stem 29. The stem 29 projects through a fitting 30 carried by the top of the container and which fitting is usually cylindrical. The extension member 7 is provided with a cylindrical aperture therein, at least extending inwardly of the bottom thereof. The inner wall 31 of this aperture embodies means cooperable with the fitting 30 to retain the extension in position on the container so that a slot 32 provided in the wall of the extension is in alignment with the discharge orifice means 26 formed in the end of the stem 29 and embodied in the push button 28. As shown in Figure 4, the extension member 7, which can be of metal or plastic material, is provided with lugs or protuberances 33 that are snapped into recesses 34 provided on the face of the fitting 30. These mating protuberances and recesses are on diametrically opposite sides of the slot 32 and in vertical alignment with the pintle 12 so that when the extension 7 is snapped in place the axis of the cam lever 11 and the orifice 26 are in respective alignment. It is clear that other means of fastening the extension 7 to the container can be embodied and as shown in Figure 5 the lower end of the extension is provided with an annular recess 35 which is snapped over an annular rim or head 36 provided on the fitting 30. In the construction shown in Figure 5, the stem 29 having a discharge orifice 26' is of slightly different structure than that embodied in Figure The movement of the striker element or dependent portion 24 of the actuating member 18 is illustrated in its cooperative relationship with the lever 11 in Figure 5. As shown, the striking portion 24 reciprocates in a plane denoted generally at A. The lower end of the striker element in moving from left to right as denoted by the arrow B, swings the lever 11 from the position shown at a to the position shown at c during which time the lever has passed through the vertical position indicated in Figure 6 and the lower end of the lever has cammed down or pushed the plunger 29' toward the container body 4 a distance sufiicient to actuate the valve so that a part of 4 1 the contents of the container are discharged through the Of course the lever in its swinging motion from position a to position c has been passed by the dependent portion 24 as shown in Figures 2 and 3 wherein.

the portion 24 is respectively on opposite sides of the lever 11. The biasing spring 13 or 13, embodied with the extension 7 must be so calibrated that it is not strong enough to snap the lever back to a vertical position but is of suflicient resiliency to retract or snap the lever 11 back to the position denoted at d in Figure 5 wherein the end face 37 can be engaged by the dependent portion 24 on the next reciprocation from right to left or in other words, when moving in the direction of the arrow F. When moving in a direction from the position shown in Figure 3 to the position shown in Figure 2, that is the direction shown by arrow E, the end of the dependent portion 24 abuts the face 38 of the lever, The particular physical disposition of the dependent portion 24 and the faces 37 and 38 are illustrative. The outer end of the lever is angled ofi to provide the faces 37 and 38 so that the dependent portion 24 can slide past the same during its reciprocation. Whether the length of the lever is such that the lower end of the dependent portion initially engages the same below the juncture of the angle surfaces 37 or 38 with the side face of the lever is immaterial so long as during the reciprocating movement the dependent portion 24 moves past the lever to permit the spring or biasing means 13 or 13' to snap the lever back upwardly into position to be engaged by the dependent portion 24 on the next reverse reciprocable movement. As stated, the biasing means is not sufficiently strong to swing the lever back with sufiicient power to depress the plunger 29 so that the swinging movement of the lever occasioned by the reciprocation of the dependent member 24 responsive to opening and closing movements of the door must be of a substantial full stroke of the actuating member 18. As indicated, the spring 25 is of greater size and strength than the biasing means 13 or 13' so that when the door is opened the pressure of spring 25 is sufiicient to reciprocate the actuating member 18 to eifect the swinging movement of the lever 18.

Figures 7 and 8 show modified forms of biasing means both however calibrated to restore the lever to the position a or d corresponding to positions a and d of Figure 5. In Figure 7 the lever is biased by a conical coil spring 39 and in Figure 8 a rubber band 40 is utilized.

It is therefore clear that I have described and illustrated an attachment for an aerosol type container including a control valve and which attachment comprises an extension 7 mounted on the container, a pivotally mounted cam lever 11 carried by the extension and engageable with vthe upper portion of an operating member or push button 28 or 28 embodied with the container and biasing means 13, 13, 39, 40 on the extension and connected with the lever 11 for restoring the lever to a position in alignment with the path of movement of the reciprocating striker portion 24 of the actuating member 18. It is further clear that the combination disclosed clearly illustrates a valve actuation for a control valve for an aerosol type container in which an element 24 reciprocable in a fixed plane eflfects pivoting movement of a cam lever to depress a valve actuator or valve stem depending on the particular structure of the aerosol container and which combination includes means biasing the cam lever for return movement to a degree insufiicient to effect a further discharge but sufiicient to restore the lever to a position within the path of movement of the reciprocable member so as to be engaged thereby upon subsequent reverse, reciprocatory movement.

As indicated this extension 7 and the lever can be constructed of plastic material or the extension may embody a metallic member having a solid slotted upper portion and a sleeved or recessed lower portion. Instead of having cooperating annular beads and recesses or protuberafic'es and recesses on-the' fitting embodied with the container and the extension respectively, the extension can be secured to the fitting by a spiined connection, by soldering or by a force fit. Additionally, the protuberance can be embodied on the fitting and the mating apertures embodied on the extension, that is the reverse arrangement of Figure 4, can be utilized in which the fitting is provided with an annular groove and an annular internal shoulder or head is provided on the cylindrical portion of the extension to be snapped into the groove or recess as the case may be.

It is understood, of course, that the resiliency of the cylindrical end of the extension, when mating protuberances and recesses are employed to securethe same to the fitting is sufficient to permit the snapping into position of the respective parts. If greater rigidity is required, the cylindrical portion can be made of metal or rather heavy gauged plastic and force fit, splined, threaded or otherwise secured to the fitting. Additionally, a separate ring or bushing can be secured to the fitting and the extension 7 secured to this bushing.

As indicated in my prior patents, the support includ ing the container can be mounted either vertically or horizontally since the valve in the aerosol container is normally closed and. there is no leakage when these containers are inverted it being necessary to depress the actuating member to eflfect a pressurized discharge. The results are clear that it is not necessary that the plunger 29 be axially bored and constitute the discharge passage since the structure embodied in Rotheim Patent 1,892,750 in which the nozzle of the aerosol container is provided with a central bore within which is slidably disposed a valve stem can be utilized. In this structure the lower end of the bore of the nozzle is flared to provide a conical seat engaged by a valve head that is integral with or permanently attached to the stem. The valve head has a vertical extension about which is disposed a coil spring which bears against an internal flange of a cap member carried by the bottom of the nozzle. This spring and/ or the pressure of the contents within the container maintain the valve in uppermost position so that it is normally closed. The upper end of the nozzle is provided with an apertured cap and a headed member having a stem which passes through the aperture in the cap and which stem is cooperable with a washer that is carried between the cap and the upper end of the nozzleso that pressure is transmitted through the stem and washer to the valve stem to permit the fluid to be discharged through an orifice in the side wall of the nozzle. With this type of structure the cam lever 11 cooperates with the headed member to push the same downwardly to eifect opening of the valve and permit an atomized discharge through the orifice in the nozzle.

In addition to the foregoing patents which are referred to, an aerosol type container embodying a valve structure as disclosed by Williams Patent 2,452,215 dated October 26, 1948, can also be utilized.

It is therefore clear that I have provided a spraying device which includes an aerosol type container having a pressurized supply of a substance such as a deodorant, fumigant or the like therein, which container includes a valve controlled outlet and a depressible plunger for controlling the valve. The valve is normally closed so that when the plunger is depressed discharge is effected. Attached to or made integral with the neck of the container I have provided an extension member on which a cam lever is mounted to pivot about an axis transverse to the axis of the plunger. The cam lever is pivotal in both directions to depress the plunger and biasing means are connected between the extension and the cam lever to normally move the same in a depressing direction so that the cam lever is always disposed in position to be engaged by a reciprocating actuator. As

indicated, this extension can be of plastic material and I have disclosed various means of mounting the same on the container.
