Claims
What is claimed is:
1. A spray-valve-actuating device comprising a base element of a
configuration for mounting about a top portion of an aerosol spray
product container and the like, said base element being a resilient
annular split clamping member including a resilient extension at
each free end, said extensions being spaced-apart and substantially
parallel, and an actuating lever removably movably connected to
said base element for disposition in respect to the plunger element
of an aerosol spray product container for selective operative
depression thereof, said actuating lever including a
terminal-mounting portion including opposed notches spaced apart a
distance less tan the spacing of said resilient extensions, said
notches removably receiving and holding said resilient extensions
in compressed relation to maintain the said clamping member
operatively in selected position on an aerosol container.
2. The spray-valve-actuating device of claim 1 in which said
extensions include opposed outward extensions and return
extensions, said return extensions having opposed outwardly faced
notches, said outwardly faced notches disposed in said opposed
notches of said actuating lever when said device is on an aerosol
container to maintain said clamping member in clamped relation on
the aerosol container and to provide a pivotal mounting for said
actuating lever for operative movement.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to the spraying art, and
more particularly to a novel spray-valve-actuating device for
aerosol spray product containers.
2. Description of the Prior Art
A variety of snap-on caps with built-in buttons providing a
comfortable grip and reducing soiling are in the prior art, but
none provide a lever ratio which is important in industrial
products used for long periods of time, and are deficient in other
respects. Various snap-on handles and trigger assemblies are
available, but those known to applicant require a relation of
container and hand, resulting in overhang fatigue in use. Many of
these cannot be detached for reuse, once mounted, and include other
disadvantages.
SUMMARY OF THE INVENTION
In brief, the present novel spray-valve-actuating device includes a
split annular wirelike base element or clamp for mounting on the
neck of an aerosol spray container, and the like, and a compact
valve-actuating lever pivotally operatively connected to the base
element and removably securing it in mounted position when the
device is on a container.
Hence, objects of the present invention are to provide a novel
spray-valve-actuating device which satisfies the long existing need
for such an item overcoming the deficiencies of devices in the art;
which reduces the fatigue of forefinger pressure that develops in
use of present such items; which eliminates overspray onto the
forefinger that occurs in use of present structures; which is easy
to attach to and remove from a container without the use of tools;
which is of low cost, permitting a user to discard the item with an
empty container or remove and reuse; which permits convenient
holding of a container for operation, right-handed or left-handed,
with forefinger or thumb; which is a positive identification of
direction of spray without examining the valve, once selectively
mounted right or left handed; which is space saving in storage in
that the lever does not project beyond the upward projection of the
container perimeter; and which otherwise fulfills the objects and
advantages sought.

DESCRIPTION OF A PREFERRED EMBODIMENT
Referring to the drawings more particularly by reference numerals,
20 indicates generally a spray-valve-actuating device constructed
to include the principles of the present invention. The device 20
includes broadly a base element or clamp 22 and an actuating lever
24.
The base element 22 is shown of split annular wirelike form and
includes an annular body portion 26, and integral spaced opposed
extensions 28 and return extensions 30, the extensions 30 being
above the extensions 28. Opposed V-notches 32 are formed at the
ends of the extensions 30. The extensions 28 and 30 are of
resilient material permitting a clamping action of the base element
22 on a container neck, and the like, upon a closing force being
applied at the V-notches 32. Notches 34 are formed in the body
portion 26, providing residual elongation of the annular body
portion 26 for tight fits.
The actuating lever 24 is illustrated as of bridging or wide
V-configuration and comprises a finger or thumb portion 36, a valve
engaging and actuating portion 38, a vertical portion 40, a
horizontal portion 42, and a depending mounting portion 44
including opposed notches 46 and an opening 48. The actuating lever
24 is short, so that the portion 36 does not extend through the
vertically projected plane of the maximum external diameter of the
container to which it is attached to conserve storage space. The
actuating lever 24 is also of light weight to obviate any opening
effect on the valve of an aerosol container.
Referring to FIG. 1, the base element 22 is shown about the neck 50
of an aerosol spray product container 52 having a plunger-type
valve actuated by depressing the plunger 54. The actuating lever 24
has one notch 46 engaging one V-notch 32 preparatory to engaging
the other notch 46 with the other V-notch 32. This is accomplished
by squeezing the extensions 30 together and rotating the actuating
lever 24 into position so that the opening 48 passes about the
other V-notch 32, permitting the latter to engage the other notch
46. To remove the device 20, it is but necessary to squeeze the
extensions 30 together, lift the lever 24, and then lift the base
element 22.
In FIG. 2, the present device 20 is shown operatively mounted on
the container 52, a forefinger 56 of a hand 58 depressing the lever
24 through engagement with the portion 36 to produce spray 60 from
the container 52. Upon release of the actuating lever 24, the valve
of the aerosol container 52 automatically closes and lifts the
actuating lever 24 by the usual spring pressure. Average size
aerosol containers 52 can be grasped by the four fingers of the
hand 58 and the lever 24 actuated by depressing the portion 38 with
the thumb 62, the relationship of fingers and container 52 being
substantially the same as in FIG. 2, or the container 52 can be
rotated 180.degree. for application of the thumb 62 to the portion
36 to spray in the opposite direction. Manifestly, if it is desired
to use the thumb 62 on the portion 36 and spray in the direction if
FIG. 2, the device 20 can be positioned on the neck 50 for regular
left-hand use. This can be accomplished without removal of the
device 20 simply by pushing in the leading extensions 28, 30 to
rotate the device 180.degree..
In FIG. 8 is shown a modified actuating lever 24' which is like
actuating lever 24, except for a reduced portion 38'.
In FIGS. 9 and 10 is illustrated a further modified actuating lever
24" which differs from actuating lever 24' only in having a
longitudinally reinforcing crimp 64.
It is clear that a spray-valve-actuating device has been provided
which fulfills the objects and advantages sought therefor.
It is to be understood that the foregoing description and the
accompanying drawings have been given by way of illustration and
example. It is also to be understood that changes in form of the
elements, rearrangement of parts, and substitution of equivalent
elements, which will be obvious to those skilled in the art, are
contemplated as within the scope of the present invention which is
limited only by the claims which follow.
