BACKGROUND INFORMATION

1. Field of The Invention

The present invention relates to the field of aerosol

sprays, such as are used in lubricant oils, air fresheners,

hair sprays, paints, foam cleaners, and compressed air.

2. Background Information

Aerosols are an integral part of our everyday lives

and are a useful way to deliver paint, insecticide,

lubricant oil, air freshener, hair products, foam

cleansers, perfumes, or compressed air. Aerosols typically

work by delivering a liquefied propellant or a compressed

gas in the form of a spray. These sprays can be composed of

small, medium, or large droplets, depending upon the

function of the aerosol.

The product to be delivered in the form of a spray-

typically travels up a "dip tube" into the "valve housing."

There is it propelled up and out through the "spray

actuator" which fits onto the "valve stem" itself. A

problem is commonly encountered in these systems when

the product to be delivered in the form of a spray must be

concentrated into a small area. This requires a nozzle to

be attached to the spray actuator in order to control the

stream of the spray. These nozzles are useful, indeed

necessary, in certain types of aerosol applications, such

as lubricant oils and compressed air, as used to clean

computer keyboards and other electronics.

When using an aerosol product that requires a

concentrator nozzle, manufacturers typically attach a

nozzle extension to the aerosol dispenser for use by the

consumer. The consumer detaches the nozzle extension and

attaches it to the spray actuator of the aerosol dispenser.

This works fine until time to store the aerosol product. At

that time the nozzle extension is removed, or falls off,

and is then very difficult, if not impossible, to find the

next time the product is needed. Some consumers attempt to

solve the problem by rubber- banding or taping the nozzle

extension to the can itself. There is a simpler solution,

and the present invention discloses it: produce a

non-detachable nozzle that is an integral extension of the

spray actuator.

SUMMARY OF THE INVENTION

In view of the foregoing, it is an object of the

present invention to provide a convenient, easy way to

concentrate an aerosol spray.

It is another object of the present invention to

provide an aerosol nozzle extension that does not detach

from the aerosol spray apparatus and become lost when not

in use.

In satisfaction of these and other related objectives,

Applicant' s present invention permits practitioners to

create an integral nozzle extension that will remain

attached to an aerosol dispenser and therefore be more

convenient for the consumer.

Applicant's approach to the problem described above is

certainly simple, but it is equally unobvious. Applicant's

integral nozzle extension permits, for the first time, the

assurance that the consumer will have access to a nozzle ¹

s spray-concentrating abilities when

using an aerosol spray product.

present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to Figure 1, the improved aerosol

dispenser of the present invention is identified generally

by the reference number 10.

Improved aerosol dispenser 10 includes an aerosol

container, not shown in the figures; an aerosol valve, not

shown in the figures,- and spray actuator 12, which fits

over the aerosol spray valve in a manner common in the

field to activate the aerosol valve and cause the

propellant and product within the aerosol container to be

delivered in aerosol form.

In Figure 1, proximal end 14 of elongate nozzle

conduit 16 is integral with spray actuator 12, being

attached by glue, or similar means common in the field.

Conduit 16 is tubular and oriented to have a continuous

passage through which is designed to permit the flow of the

compressed materials held within the aerosol container. In

the preferred embodiment shown in figure 1, corrugated,

flexible segment 20 is medial of proximal end 14 and distal

end 18 of conduit 16. In this embodiment, conduit 16 can be

bent at segment 20, to allow easier storage of the aerosol

dispenser without detaching conduit 16. This solves the

problem of misplacing conduit 16 between uses of the

aerosol dispenser.

In Figure 2 is shown a different attachment means

consisting of proximal end 14 of conduit 16 comprising a

projecting lobe member 22 which is configured to reversibly

interlock with lobe-receiving recess 24 in the aerosol

actuation means, in this embodiment by means of two lobe

receiving members 26 and 28 which fit around lobe member 22

and which fit into lobe-receiving recess 24. As in the

other embodiment shown in Figure 1, this solves the problem

of misplacing conduit 16 between uses of the aerosol

dispenser and yet would allow conduit 16 to be removed for

cleaning when necessary. Of course, although not shown in

Figure 2, conduit 16 in this embodiment could also include

a corrugated, flexible segment 20 as shown in Figure 1.

Although the invention has been described with

reference to specific embodiments, this description is not

meant to be construed in a limited sense. Various

modifications of the disclosed embodiments, as well as

alternative embodiments of the inventions will become

apparent to persons skilled in the art upon reference to

the description of the invention. It is, therefore,

contemplated that the appended claims will cover such

modifications that fall within the scope of the invention.
