I I INVENTOR. LOUIS F. KUTIK F|6.12 BY ATTORNE United States Patent Office 3,138,331 Patented June 23, 1964 3,138,331 ACTUATOR FOR PRESSURIZED DISPENSING CANS Louis F. Kutik, 5601 SW. 56th St., Fort Lauderdale, Fla. Filed July 30, 1962, Ser. No. 213,424 10 Claims. (Cl. 239-337) This invention relates to spraying devices, and more particularly to a device adapted to be fitted upon the top of a pressurized or spray can to spray the contents thereof.
In many cans of this kind, such as those which are used for containing insecticides, deodorants, liquid soaps and many other liquid preparations, a plun er is provided at the top which, upon its depression, opens a valve and causes the spraying out of the can contents. The ease with which these cans can be sprayed often causes them to be taken from the shelves in stores and test sprayed by customers. This results in the reduction of the can contents so that many of the cans when purchased, are partially emptied or do not contain the required full amount of contents. Also, some of these cans are so constructed that the possibility of them being accidentally sprayed is likely.
It is an object of the present invention to provide a spraying device which will prevent the unauthorized or accidental spraying of a cans contents; which can be made economically, and if desired in whole or in part of a plastic material; which will be provided with closure means preventing accidental spilling; which will aid in directing the spray toward the desired area of dispersion; which can be made either as a removable or non-removable attachement to a spraycan, and which will possess numerous other advantages apparent to those skilled in this art.
More particularly, the invention contemplates the provision of a cup-shaped cap member fitted over the plunger of a pressurized container or spray can, and which cap member is provided with a hinged lever extending across the top of the cap member, the cap member being provided in its top wall with an aperture for permitting access to the plunger, and the lever carrying a bodily-shiftable element capable of movement to either align it with the aperture and permit it to engage the plunger, or else be moved to disalign it with the aperture so that the plunger will not be moved when the lever is moved downwardly.
With these and other objects to be hereinafter set forth in view, I have devised the arrangement of parts to be described and more particularly pointed out in the claims appended hereto.

Referring to the drawings, and more particularly to FIGS. 1 to 6 thereof, there is therein shown at 1, a part of a can or pressurized container upon which the improved spray device or head is adapted to be fitted. Such a can is provided at the top with a neck, not shown, but which is formed with a bead adapted for interengagement with an annular groove 2, formed at the bottom part of a cupshaped cap member 3. The improved spray head, of which the cap 3 forms a part, is preferably, but not necessarily made of molded plastic material and if desired the other parts of the device may also be composed ofa suitable plastic. A plastic such as polypropylene is suitable for the purpose since such material is resistant to the eitects of acids, paints and chemicals.
By the attachment of the cap 3 to the top of the can, the spraying device is securely fitted in place. The cap 3 includes a centrally-located open bottom chamber 4 within which a head 5 is slidable, said head being provided with an outlet opening 6 in its side wall, and through which, when the head is depressed as shown in FIG. 5, the fluid in spray form will be forced out through a frusto-conical outlet passage 7 provided in the side of the cap. The frusto conical passage 7 when aligned with the opening 6 permits the contents of the can to be discharged in a conical spray and the passage 7 causes the material from the can to be mixed with air and a turbulence is created in the passage .7 wheerby the insecticide or other material is discharged in a more efficient manner. The lower end of the head 5 is provided with a stem 8 which extends down into the can I. On its upper end, the head 5 is provided with a square shank 9 guided in a complementarily-shaped opening 10 provided in the top wall 11 of the cap. The parts 5, 8 and 9 co-operate in forming a plunger which, upon its depression, causes the ejection of the liquid contents of the can out of the aligned outlets 6 and 7.
The opening 10 in the cap 3 is normally closed by a membrane or diaphragm which prevents leakage or evap oration of the can contents. The diaphragm 12 requires rupturing to permit of access to the shank 9 by a depressing pin or similarly-operating element to be presently described.
At 15 is indictaed a pivoted lever, provided at one end with a down-turned finger piece 16, which may be roughened or serrated as shown at 17 for facilitating finger engagement with the lever. The finger piece 16 extends downwardly alongside the body 3 which greatly increases the leverage with respect to the lever 15 and allows the operator to actuate the lever in a balanced position with the hand grasping the can while the operator depresses the finger piece 16 with the thumb. As clearly seen in FIG. 3, the lever 15, including the finger piece 16 thereof, is of channel shape in cross section, with the channel opening downwardly, and at its forward end it is formed with a groove 17 for snap engagement with a cylindrical head 18 formed integrally with and on the top of the cap 3. By this interengaging arrangement of the parts 17 and 18, a hinged connection is established between the lever 15 and the cap 3.
Extending downwardly from the lever 15 and projecting out of the channel thereof, is a guide finger 19 provided with a slightly hooked end 20, and said finger is slidable through a guide opening 21 provided in the top wall 11 of the cap 3. In its raised position, the finger has its 'tOOkfid end 26 engaging under the top wall lit adjacent to the guide opening 21 so that the limited upward swing of the lever is determined.
Normally extending laterally of the lever 15 as shown in FIG. 1 is a tab or flap 22, and extending from the then upper face of the tab or flap is a pin 23, which pin constitutes a depressing pin which, when properly positioned in axial alignment with the shank 9, will, upon downward depression of the lever 15, depress the shank 9 down to the position shown in FIG. 5, wherein the outlet opening 6 in the head will be properly aligned with the outlet passage 7 and the spray will accordingly be ejected from the can.
While the filled can remains on the shelves of a store or elsewhere where it is not intended for unauthorized use, the tab or flap 22 is intended to remain positioned laterally of the lever as shown in FIG. 1. When the parts are in the position shown in FIG. 1, lever 15 may be freely depressed, but since the pin 23 projects upwardly and is disaligned from the shank 9, the head 5 will not be reached by the pin and will not be depressed and hence no spraying will take place.
The flap or tab 22 is integrally connected to the lever 15 by means of a flexible web 24 constituting a hinge which, when doubled upon itself as shown in FIG. 3, will perrnit the tab or flap 22 to be swung underneath the channelled under face of the lever and will bridge the channel thereof, as clearly seen in FIG. 3. When the tab or flap 22 is located in this position, the pin 23 thereon will be facing downwardly and will also be in axial alignment with the aperture 18 and the shank 9 located therein. Thus, when the lever 15 is then depressed, the downwardly-projecting pin 23 will puncture the diaphragm 12 and will then contact with the upper end of the shank 9 forcing the head 5 downwardly to the spraying position, substantially as shown in FIG. 5.
In order to hold the tab 22 in its operative position across the bottom of the lever 15 as shown in FIG. 3, a locking arrangement is provided by forming the free end of the tab or flap 2.2 with a hook portion for engagement with a bead or projecting rib 26 formed on the lower end of one of the side walls of the lever 15.
From the foregoing, the operation of the improved spray head will be readily understood. The condition of the parts of the device while the can is in a store or stored elsewhere, is shown in FIG. 1, wherein it will be observed that the tab or flap 22 is disposed laterally of the lever 15 and with its pin 23 projecting upwardly. While the parts are in this position, the lever 15 may be freely depressed without resulting in the spraying of the can contents, since the head 5 will not be depressed. When it is desired to place the spraying device in the required operative position, the tab or flap 22 is then swung downwardly on its hinge 24 to bring it beneath the lever 15 and hold it in such position by causing the interengagernent of the locking parts 25 and 26. Then, when the lever 15 is depressed, the pin 23 being aligned with the shank 9, will puncture the diaphragm 12 and depress the head 5 to cause the liquid contents of the can to be sprayed out through the aligned outlets 6 and 7.
The parts may be left in the operative position just described, or the device can be rendered inoperative by swinging the tab or flap 22 outwar ly to its lateral position as shown in FIG. 1, so that subsequent handling by children for example, and the depression of the lever 35, will not result in spraying.
In the embodiment of FIGS. 7and 8, the ilap or tab therein shown at 22a is similar to that shown at 22 in the first-described embodiment, except that the tab 22a is not provided with a depressing pin. In this embodiment, the shank shown at 9a is increased in length so that it projects above the top wall 11 of the cap 3 and extends into the channel 46 of the lever 15 when the lever is depressed. As long as the tab or flap 22a is extended laterally of the lever 15 as was described with respect to the tab 22, the lever 15 when downwardly moved, will not depress the shank 9a since the shank will fit in the channel of the lever and will not be moved. However, the flap or tab 22a bridges the channel of the lever, as shown in FIG. 8, the tab or flap 22a will, upon the descent of the lever 15, contact with the top of the shank 9a to thereby depress the same bringing the head 5 down to the position to cause spray ejection.
A further embodiment is shown in FIGS. 9 to 11 inclusive. Therein the lever 15 is provided in its top wall with an elongated slot 30 in which a slide 31 is mounted. Said slide is provided with a roughened or serrated upper surface 32 for engagement by the finger of the operator to move the slide back and forth as required, within the limit permitted by the slot. The opposite edges of the slide are grooved as shown at 38 to receive the side edges of the slot 30 and to enable the slide to be easily moved back and forth. When the slide is in its rearward or retracted position, as shown in FIG. 10, any downward depression of the lever 15 will bring the end of a depressing pin 23b, provided on the bottom of the slide 31 and projecting downwardly therefrom, into contact with a clearance groove 34 provided in the top wall 11 of the cap. This inclined groove is effective to guide the pin 2% since the same is of relatively rigid material, causing no damage to the pin. At this time, the pin 23, being disaligned from the opening 10, will neither rupture the diaphragm 12 nor depress the head 5. Therefore, as long as the slide 31 is in its retracted position the device will remain inoperative as far as spraying is concerned. When it is deisred to spray the contents of the can, the slide 31 is advanced forwardly in the slot 30 by pressure of the finger of the operator, to the position shown in FIG. 10, whereupon depression of the lever 15 will cause the pin 23]), then positioned above the head 5 to puncture the diaphragm 12 and depress the head 5 to align the spray outlets 6 and '7 and cause spraying of the can contents.
It will be apparent from the foregoing, that a spraying device is provided which is clean and easily operated. When in the condition shown in FIGS. 1 and 10, the parts are so arranged that inadvertent or unauthorized depression of the operating lever will not cause spray ejection. Because of the fact that the entire device may be made of molded plastic it can be inexpensively made and sold, The large lever 15 and its location provides for easy operation and for the direction of the spray toward the area to be sprayed, and many other advantages are apparent to those skilled in this art.
