OPERATING DEVICES FOR AEROSOL DISPENSERS Filed Sept. 28, 1959 FIG. 2

INVENTOI? Gt'OFFRfY H. WOOD By 2A TTO/PNEYS United States atet 3,028,055 OPERATING DEVICES FOR AERGSOL DISPENSERS Geolfrey H. Wood, Toronto, Ontario, Canada, assignor to G. H. Wood and Company Limited, Toronto, On-

tario, Canada Filed Sept. 28, 1959, Ser. No. 842,797 4 Claims. (Cl. 222-180) This invention relates to an operating device for an aerosol dispenser of the type comprising a container and a cap mounted on the container to be movabl relatively thereto, movement of the cap towards the container operating the dispenser. A dispenser of this type conveniently comprises a substantially cylindrical container having a hollow valve stem projecting axially from one end thereof. A substantially cylindrical cap, closed at one end, fits over said one end of the container to be slidable relatively thereto and the hollow valve stem of the container is received within a sleeve at the closed end of the cap; the sleeve being in communication with a nozzle projecting from the side of the cap. Movement of the cap towards the container depresses the valve stem allowing the aerosol within the container to issue through the hollow valve stem and be directed out through the nozzle.

An object of the present invention is to provide a simple and efficient device for operating such a dispenser.

The invention will be described by way of example with reference to the accompanying drawing in which:

FIGURE 1 is a perspective view of a domestic garbage can having a device according to the invention secured to the inside of its lid, parts of the can being cut away to show the location of the device,

FIGURE 2 is a side elevation of the device in an inoperative position with the dispenser secured in the device, and

FIGURE 3 is a view similar to FIGURE 2 showing the device in its operative position.

Referring now to the drawing, a garbage can has a body indicated generally at and has a bottom 11 and a hinged lid 12; the lid is hinged to the body 10 by a hinge 13. A device for operating an aerosol dispenser is indicated generally at 14 as secured to the underside of the lid 12.

The device 14 includes a clamping body having a base 15 and a double-armed spring clip 16 secured to the base. At one end of the base 15 is provided a first flange 17 having an aperature 18 therein. An angled lever 19 passes through the aperture and is provided with a second flange 20, the portion of the lever 19 which is horizontal in FIGURE 2 constituting an operating arm. The first flange has a lug 21 formed therein and an arcuate spring 22 extends between the lug 21 and the lever 19 and is riveted to the lever at 23. An operating knob 24 is also secured to the lever 19 by rivet 23 and projects through an aperature 25 in the lid 12 on the garbage can. The spring 22 urges the lever 19 to a position such that the first and second flanges are held in contact with one another as shown in FIGURE 2,

An aerosol dispenser comprising a container 26 and a cap 27 is shown as held in position in the device. The container 26 is held by the spring clip 16 and is located at one end by a down turned flange 28 integral with the base 15. A nozzle 29 is formed in a side of the cap 27 and the end of the cap remote from the container is in contact with the second flange as shown in FIGURE 2. The first flange 17 has an extension 30 extending generally perpendicularly from the flange and this extension is provided with a slot 31, see FIGURE 1, which receives the nozzle 29. The base 15 of the device is spot welded to the lid of the garbage can 12 as at 32.

The operation of the device is as follows, in FIGURE 2 it is shown in its inoperative at rest position. It will be seen that the second flange 20 is forced into contact with the first flange 17 by the arcuate spring 22 and furthermore that the second flange 20 is interposed between the first flange 17 and the end of the cap 27 which is remote from the container. Moreover, the nozzle 29 of the dispenser is received in the slot 31. If now the operating knob 24 is moved downwardly in the direction of the arrow A in FIGURE 3, the lever 19 will pivot about a fulcrum provided by the walls of the aperture 18 and the second flange 20 will move in the direction of the arrow B and away from the first flange 17. Movement of the second flange in the direction of the arrow B will move the cap of the container in the direction of the arrow C and will operate the dispenser so that aerosol is dispensed through the nozzle 29. The nozzle 29 will slide in the slot 31 as the dispenser is operated. When pressure is removed from the operating knob 24 the spring 22 will return the parts to the position shown in FIGURE 2. The slot 31 ensures that the aerosol discharged by the dispenser will be directed downwardly into the garbage can,

It will be seen that the invention provides an extremely simple and eflicient device for operating an aerosal dispenser and that such a device has particular application to the lid of a garbage can or similar container.

It will be understood that the form of the invention herewith shown and described is a preferred example and that various modifications may be carried out without departing from the spirit of the invention or the scope of the appended claims.

What I claim as my invention is:

l. A device for operating an aerosol dispenser of the type comprising a container and a cap mounted on the container to be movable relatively thereto, movement of the cap towards the container operating the dispenser; the device comprising a body, a first flange of the body for mounting adjacent to, but spaced from, the end of the cap remote from the container, said flange having an aperture therein and a lug remote from said aperture and extending away from said end; an angled lever mounted in said aperture, said lever having an operating arm and a second flange for interposition between the first flange and said end of the cap; and an arcuate spring interposed between the first flange and the lever to normally hold the lever so that the second flange is in contact with the first flange, said spring being secured at its one end to the operating arm of the lever remote from the second flange and at its other end engaging said lug on the first flange, pivoting of the lever against the spring and about a fulcrum provided by the walls of the aperture moving the second flange away from the first flange to move the cap to operate the dispenser.
