United States Patent F 3,331,537 RING TYPE FINGER SUPPORTED DEFENSIVE SPRAY DISPENSER Elmer M. Benedict, 506 State St., Schenectady, N.Y. 12305 Filed Aug. 13, 1965, Ser. No. 479,525 1 Claim. (Cl. 222-211) This invention relates to an improved type of defensive spray dispenser.

An object of the invention is to provide an improved ring-type finger supported defensive spray dispenser whereby a liquid spray or gas with an incapacitating agent may be directed from a distance into the face or eyes of an assailant temporarily incapacitating him and giving the possible victim a chance to escape.

Another object of the invention is to provide a ring supported, compressible, defensive spray dispenser which would be engaged over a finger of the user with the compressible bulb or dispenser held concealed in the palm of a hand, whereby if attacked by a possible assailant, a stream of fluid or gas with an incapacitating agent could be directed at a distance of from ten to fifteen feet into the face or eyes of the possible assailant, thus incapacitating him while the possible victim made his or her escape.

A further object of the invention is to provide an improved ring supported aerosol-type defensive spray dispenser which would be supported on a finger while the aerosol dispenser with adjustable nozzle would be concealed in the palm of the hand, whereby the same could be instantly operated to eject a liquid stream or gas with an incapacitating agent from a distance into the face or eyes of a possible assailant, thus incapacitating him temporarily while the possible victim made his or her escape.

A still further object of the invention is to provide an improved ring-type defensive spray dispenser which would be highly efiicien-t in use and relatively inexpensive to manufacture and produce.

Other objects will appear as the description proceeds.

In the accompanying drawings which form a part of this application:

FIGURE 1 is a side elevation, partly in section, of a hand holding my improved ring-type defensive spray dispenser;

FIGURE 2 is a sectional view taken on the line 22 of FIGURE 1;

FIGURE 3 is a partial sectional view of an adjustable nozzle arrangement;

FIGURE 4 is a side elevation of the ring support and nozzle; and

FIGURE 5 is a side elevation, partly in section, of an aerosol-type defensive spray dispenser.

Like characters of reference are used throughout the following specification and the accompanying drawings to designate corresponding parts.

In carrying out my invention, I provide an improved ring-type or finger supported defensive spray dispenser 3,331,537 Patented July 18, 1967 comprising a compressible bulb or container 1 having an air valve 2 therein and a hub portion 3 having a discharge passage 4 therethrough, to the inner end of which is connected a curved outlet tube 5 extending into or adjacent the bottom inner wall of the said bulb or container 1, so that liquid or gas may be discharged from any position from the bulb or container when held in a hand 6 and compressed.

A hollow ring support 7 is provided with a threaded nipple 8 which will be screwed into the apettured hub portion 3, and an apertured nozzle 9 will be supported by and attached to the ring support 7 diametrically op posite the nipple 8, whereby when the bulb is compressed after inserting a finger through the ring support 7, a stream of liquid or gas with an incapacitating agent may be directed from a distance of from ten to fifteen feet into the face or eyes of a possible assailant. If desired, a compressible extension tube 10 may be supported between the ring support 7 and a bushing 11 which supports the adjustable nozzle 12, which would be threaded to squeeze the extension tube 10, as clearly shown in FIGURES 2 and 3, to selectively vary the size of the stream of liquid or gas being discharged.

In lieu of the compressible bulb or container 1, an aerosol container 13, as shown in FIGURE 5 of the drawings, may be used with any desired type of controlling valve.

Many minor changes in detail of construction may be resorted to without departure from the spirit of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

A ring-type or finger-suported defensive spray dispenser comprising a compressible container for holding a liquid or gas with an incapacitating agent, an air valve in said container, a hollow finger-engaging ring attached to said container, an elongated compressible tube within said container and forming a fluid passageway from said container to said ring, and an adjustable nozzle connected to said finger-engaging ring to vary the size of the stream of liquid or gas with the incapacitating agent being discharged when said compressible container is squeezed, said container being completely enclosed within the closed hand with only said ring exposed when said device is ready for use.
