Complete Specification for the Invention entitled:

"SPRAY CONTAINER DELIVERY DEVICE"

The following statement is a full description of this invention, including the best method of performing it known to mo'us

This invention relates to containers which have

spray devices for application of compositions such as de-

odorants or antiperspirants to the axilla.

In recent years pressurized or aerosol products

for underarm use, such as antiperspirants and deodorants, have become extremely popular. Aerosol sprays have been

found far superior in many respects to the squeeze bottle

sprays and gel-type products which are applied by contact of a gel stick to the axilla. The problems associated

with the course spray of the squeeze bottle spray product

and the problems associated with the direct contact of the stick gel product are well known. Therefore, aerosol spray products, which eliminated the contact of stick

gels and the cpurse spray and dripping associated with squeeze bottle sprays, were well received and continued to be widely used.

However, there are problems associated with de-

vices used for pressurized delivery of underarm spray 2 products. One primary problem is misdirection of product 20 and another is excessive overspray or wasted product. S• These problems have been widely experienced by users of

such products.

Another problem associated with the well known

and widely used aerosol underarm products is difficulty

in obtaining an even application of the product to the

underarm are. For example, a heavy concentration is ap-

plied to one particular area while a very small amount is

applied to another area. Product is wasted in many cases

due to uneven application. Another significant problem associated with such packages and sprays is related to ease of applica- tion. It often would be required to assume an unnatural hand and arm position to obtain a proper application of an aerosol product of the prior art.

Accordingly, the invention provides a container-

delivery device for an underarm spray product, comprising: recervoir mcans to contain said product, said means having

a lateral wall configured to be readily grasped in hand, said reservoir means including a discharge port; valve

10 means connected to said reservoir means to control the o 0

flow of said product through said port; actuator means connected to said valve means; elongated head connected to and extending from said reservoir means, said head

forming an elongated concave surface extending therealong to form a substantial mirror-image of an axilla, said head defining a passageway terminating through said sur-

face; and conduit means connected with said port and ex-

tending in said passageway, said conduit means terminat- *2 ing in a spray orifice defined therein near said concave

20 surface. In one form of the invention, an elongated de-

livery head extends from the container body and includes

an elongated concave surface surrounding a spray orifice.

The concave surface approximates a mirror-image of the

axilla. The elongated head can readily be positioned underneath the arm with the concave surface facing toward

the underarm area at fairly close range, such as with the

boundary line of the concave surface touching or close to the approximate boundary line of the axilla. This device

provides directional control, even application of product and ease of application. Tt prevents or drastically re- duces misdirection, overspray and product waste. In preferred embodiments, an actuator trigger is located near the surface of the container body and/or in a particular location relative to the concave surface to provide improved ease of application. In other pre- ferred embodiments, the concave surface is of a certain shape or orientation to provide improved ease of applica- *0 tion.

o 10 The invention advantageously provides a pres- surized delivery system for underarm spray products which 0*

*avoids the problem of overspray and product waste, which

provides directional control and even application of such

products and which allows application of a product to the axilla from one position, avoiding the necessity of

.moving the package during application.

In the accompanying drawings:

Figure 1 is a perspective view of an embodiment of the container-delivery device;

20 Figure 2 is an enlarged top plan view of the device of Figure 1;

Figure 3 is a fragmentary sectional view taken

along section 3-3 as indicated in Figure 2; Figure 4 is a fragmentary view as in Figure 3,

but showing the actuator means in depressed position

whereby the valve means is actuated; and Figure 5 illustrates the method in which the

device is used. Figure 1 is a perspective view of a preferred

container-delivery unit 10 of this invention. Package has a reservoir means 12 which is a cylindrical body of greater length than width. Reservoir 12 may be a two or three piece metal can. Contained within reservoir 12 is an underarm spray product such as an antiperspirant or deodorant. Also included within container 12 may be a liquid or gaseous propellant which is used to expel the underarm spray product through port 14 which is defined in reservoir means 12 and which is centered in one end of the cylindrical container. o

10 Connected to container 12 is a delivery head 16

which extends therefrom and which is elongated generally

in the direction of the axis of container body 12. Head 0**

16 is preferably a molded plastic piece which is friction

or snap fitted to container body 12 as shown at numeral 18.

Delivery head 16 forms an elongated concave surface 20 defined by a boundary 22 which forms a gener- ally elliptical loop falling substantially in a single plane. Delivery head 16 defines an aperture or passage- 20 way 24 through concave surface 18 and aligned with port

14. Passageway 24 is located in a generally central por-

tion of concave surf ace 20. Delivery head 16 will be de-

scribed in greater detail further herein.

A valve 26 is connected to container 12 and is

used to control the flow of a pressurized underarm prod-

uct from reservoir 12 through port 14. Actuator 28 is a

second class lever, having as its fulcrum a pivoting con-

nection 30 by which actuator 28 is attached at one end

to internal structural element 32 of delivery head 16, Actuator 28 extends from connection 30 across port 14 and and valve 26 in a first radial 'irection and terminates in

II alignment with lateral wall 34 of container 12. This terminating portion of actuator 28 is substantially flush with lateral wall 34. A trigger portion 36, which is ap- proximately the width of the thumb of an adult, is locat- ed near lateral wall 34. Integrally molded with actuator 28, in a posi- tion aligned with port 14 and passageway 24, is conduit

38. Conduit 38 joins with valve stem 40, which forms port 14. When actuator 28 is depressed by application of

10 pressure on trigger portion 36, valve stem 40 is depressed 0* and the product contained within reservoir 12 flows

through valVe stem 40, conduit 38 which is joined thereto,

and exits from conduit 38 by passing through spray orifice

42 which is defined by conduit 38. Spray orifice 42 is

located near conca-. surface 20. Spray orifice 42 is de-

signed to provide a spray pattern which will substantial-

ly cover the axilla, as is described hereinafter.

In the preferred embodiment shown in the figures, trigger portion 36 of actuator 28 is moveable in a direc-

20 tion generally along lateral wall 34 and in a direction generally parallel to the axis of container Referring again to concave surface 20, boundary

22 thereof is generally an elliptical loop of a size ap-

proximately conforming to the boundary of the axilla when the arm is in a lowered position. When the elongated de-

livery head is inserted under the arm and placed in the

area of the axilla as shown in Figure 5, recessed or con-

cave surface 20 forms a substanti l mirror-image of the

axilla area. When the valve is actuated, a spray dis-

charged through orifice 42 will substantially cover the area of the axilla with an underarm product, such as a deodorant or antiperspirant. Because of this method of application, overspray and the attending problems will be eliminated or substantially reduced.

In this embodiment, boundary 22 of surface

is generally within a single slant plane. Preferably,

the spray from orifice 42 will intersect a substantial

portion of that port of the slant plane which is enclosed

within boundary 22. With this sort of wide spray pat-

10 tern, substantial coverage of the axilla may be achieved

without movement of head 16 during application.

In this preferred embodiment, the plane of boundary 22 is slanted at about 45 degrees to a plane

normal to the axis of container 10. This slant orienta-

tion further facilitates convenient application of the oe

unuerrmn product.

In the preferred embodiment shown in the fig-

ures, trigger portion 36 of actuator 28 is near that por-

tion of concave rurface 20 which is closest to the lateral o.

20 wall of reservoir 12. This general arrangement of the

actuator provides very easy application in the manner

illustrated in Figure

While the cylindrical container shape of the

preferred embodiment shown in the drwings is highly pre-

ferred, other configurations may be u3ed. It is neces-

sary only that the lateral wall of the container be con-

figured to be readily grasped in hand in a manner making

application of the contained underarm spray product con-

venient. Metal containers such as standard two or three

piece cans may be used. However, plastic aerosol con- tainers and a wide variety of other types of containers are usable in the container-delivery unit of this inven- tion. The delivery head shown in the figures is pre- ferred from a standpoint of ease and convenience of use. However, there may be significant variations in the con- figu. ation o2 the delivery head without departing from the spirit and scope of this invention. For example, the boundary which defines a concave surface need not fall in one plane but may be arched to some degree. Further, al- though the slanted boundary plane shown in the figures is preferred, other orientations are within the scope of this invention. The delivery head of this invention may be con- o veniently molded in plastic in a form which is readily attachable to the dome of arn aerosol container or some a*

S" other portion thereof. However, the delivery head may be made of other materials and by other methods and may be

attached to a container in a' variety of ways, as will be known to those skilled in the art who are made aware of

this invention. Indeed, the delivery head may be molded

together with the container body as a single piece or may be formed as a single piece with the container body by

some other method.

The actuator arrangement shown in the drawings e o is highly preferred from the standpoint of convenience

and ease of use in the normal position of application to the underarm area. It is convenient to displace trigger

portion 36 in an axial direction generally along lateral

wall 34. However, displacement in other directions along lateral wall 34 may be convenient in other embodiments.

Indeed, the movement of trigger portion 36 may be by a

radial depression or some other convenient motion. Locat-

ing trigger portion 36 near that portion of concave sur-

face 20 or boundary 22 which is closest to the cylindrical

lateral wall of the container makes the application pro-

cedure quite convenient and natural.
