Description
BACKGROUND OF THE INVENTION
The present invention relates generally to the field of painting
accessories and more particularly, is directed to a removable paint
can agitator and pouring top.
Prior workers in the field have sought to develop paint agitators
for use with paint containers and prior designs of which I am
familiar have included agitators adapted to be affixed to a usual
paint container by utilizing spring clips to detachably engage the
rim of the paint can. These prior art mixers have included a bent
metal agitator but have not included a complete container cover and
pouring arrangements.
Other workers in the field have designed combined containers with
stirrers therein which are integrally fabricated at the time of
container manufacture. This type of prior art design proved to be
quite costly in use inasmuch as the entire container and mixer
combination had to be discarded once the liquid contents of the
container had been consumed. Other workers in seeking to solve the
problem of agitating the fluid contents of paint containers have
developed other mixer designs of complicated construction and
configuration, all of which resulted in mixing devices that were
more or less satisfactory in operation but all of which proved too
costly in construction and use to achieve general acceptance by the
purchasing public.
SUMMARY OF THE INVENTION
The present invention includes a removable lid of design to tightly
close directly upon the container opening configuration of the
usual paint can. The lid may be fabricated of plastic or metallic
construction and includes a pair of diametrically opposed openings
of similar design, one of which is employed as a pouring opening
and the other cooperates during the pouring operation as a venting
opening.
A central boss axially positions in the removable lid and is
provided with a bearing to receive a portion of the agitator in
rotatable engagement therein. An external crank connects to the
agitator above the boss to provide easily turnable means to rotate
the agitator from without the container. The crank may be designed
as a separate article to remove from the agitator exteriorly of the
container when it is so desired.
By providing a combination lid and agitator, all of the
difficulties experienced by prior workers in the art can readily be
overcome. Specifically, by providing a removable lid, the invention
may be utilized a number of times with a plurality of paint
containers. The repeated use of the device renders it economically
feasible inasmuch as the manufactured cost can be distributed over
a large number of repeated periods of operation.
It is therefore an object of the present invention to provide an
improved paint can agitator and pouring top of the type set
forth.
It is another object of the present invention to provide a novel
paint can agitator and pouring top which incorporates an agitator
for mixing the paint within the container and which further
includes an integral pouring spout so that the mixed paint can be
conveniently poured from the container.
It is another object of the present invention to provide a novel
paint can agitator and pouring top including cooperating pouring
and venting openings whereby the liquid contents of the container
may be precisely poured without gurgling, spilling or dripping.
It is another object of the present invention to provide a novel
paint can agitator and pouring top which incorporates a freely
rotatable agitator extending through the top, the lower end of the
agitator being receivable into a paint can for agitating the paint,
and the upper end having a crank attachment for rotating the
agitator either by hand or by an electric power tool.
It is another object of the present invention to provide a novel
paint can agitator and pouring top that is inexpensive in
manufacture, simple in construction and trouble-free when in
use.
Other objects and a fuller understanding of the invention will be
had by referring to the following description and claims of a
preferred embodiment thereof, taken in conjunction with the
accompanying drawings wherein like reference characters refer to
similar parts throughout the several views and in which:

DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION
Although specific terms are used in the following description for
the sake of clarity, these terms are intended to refer only to
particular structure of my invention selected for illustration in
the drawings and are not intended to define or limit the scope of
the invention.
Referring now to the drawings, I show in FIG. 1 a paint can
agitator and pouring top 10 combined in a unitary assembly 11 for
use in conjunction with a conventional paint container 17 which is
usually of one gallon capacity. The paint can agitator and pouring
top assembly includes a lid 12 which is preferably formed of a
single sheet of material having sufficient strength and pliability
to co-act with the configuration at the top closure of the paint
container 17, and may be formed of polyethylene plastic material.
The lid 12 forms to a generally circular configuration and includes
flat top 13 which terminates outwardly in a peripheral construction
14 including the downwardly extending flange 15 which is sized to
closely overfit the top of the paint container 17. The lower end of
the flange 15 terminates downwardly in an inwardly extending bead
16 of suitable dimensions to snap upon and lock the pouring top 10
upon the upper end of the paint container 17. A downwardly
extending, annular lip 18 integrally forms in the bottom of the lid
12 inwardly from the flange 15 and is sized to fit within the usual
circular groove normally formed in the top of the conventional
paint container 17 about the top access opening thereto.
A pair of diametrically opposed pouring spouts 19 integrally form
into the lid 12 and extend upwardly from the upward surface of the
flat lid top 13 for pouring and venting purposes as hereinafter
more fully set forth. Each pouring spout 19 is preferably
cylindrically formed to the same dimensions and each spout 19 is
provided with a closure 20 which may be a tight, sliding fit
thereon. Each closure cap 20 frictionally fits over its associated
spout 19 for easy removal during the paint pouring operation. It
will be appreciated that either cap 20 may be removed to provide a
passage from the interior of the paint container 17 through the top
13 thereby exiting the fluid contents at either pouring spout 19.
During the pouring operation which is easily accomplished in
well-Known manner by simply tipping the container about its axis,
the fluid pours through the first spout 19 and the second pouring
spout 19 readily serves as a vent by simple removing its associated
cap 20 to thereby allow air to freely circulate inside the
container above the liquid level of the container contents.
The lid 12 is provided with a central, upwardly extending boss 21
which is formed with a central opening 22 in axial alignment with
the lid 12. If desired, a bushing (not shown) may be inserted into
the central opening 22 to provide additional bearing surface for
the agitator intermediate portion 50. The agitator is preferably
formed of metal rod of circular cross sectional configuration with
the intermediate portion 50 of the rod inserting through the
central opening 22 in bearing relation therein.
As best seen in FIG. 1, the lower portion of the agitator 23
includes a top rod section 51 bent at right angles to the
intermediate rod portion 50 and which is arranged to rotate in a
plane substantially parallel to and spaced beneath a plane drawn
through the flat top 13. The top rod section 51 terminates
outwardly near the outer periphery of the container 17 in the
downwardly extending leg 24 which bends at right angles to the top
rod section 51. The downwardly extending leg 24 extends generally
parallel to the container side wall to thereby sweep and agitate
the container contents in a circular manner immediately inwardly
from the container side wall. The downwardly extending leg 24
downwardly terminates in a horizontal leg 25 which extends
diametrically across the lower portion of the paint container 17
near the bottom thereof to thereby agitate and mix the fluid
contents of the container near the bottom upon rotation of the
agitator 23. The horizontal leg 25 terminates diametrically
opposite from the downwardly extending leg 24 and bends to form an
upward diagonal leg 26 which extends generally diametrically
diagonally from the bottom edge of the container to the upper edge
of the container. The diagonally extending leg 26 diametrically
extends so that during the rotational operation of the agitator 23,
the leg 26 serves to sweep across and thoroughly mix a major
portion of the fluid contents retained within the container 17.
THus it is seen that the top rod section 51 agitates the fluid
container contents near the top of the container, the horizontal
leg 25 agitates the fluid contents near the bottom of the
container, the downwardly extending leg 24 agitates the fluid
contents peripherally about the side walls of the container and the
upward diagonal leg 26 agitates the central portion of the fluid
contents of the container 17.
Referring now to FIG. 2, a modified configuration of the pouring
spout 27 is illustrated wherein the upper end 52 of the spout 27 is
provided with a plurality of peripherally spaced, downwardly
extending slots 28 to permit the terminal ends of the spout to be
slightly inwardly collapsed to receive the cap 29. The spout 27 is
provided with an annular bead 31 for cap securing purposes. As
illustrated, the cap 29 is provided with an interior cooperating,
annular, outwardly extending groove 30 near the top thereof to
cooperate with the pouring spout annular bead 31. THus, upon
pushing the cap 29 downwardly upon the spout 27, the cap side wall
53 will overfit the spout 27 and press downwardly and inwardly upon
the extending annular bead 31 to thereby compress the upper end 52
of the spout at the downwardly extending slot 28 thereof. Upon
pushing the cap downwardly, the outwardly extending groove 30 will
seat upon the annular bead 31 to thus secure the cap in sealing
position over the pouring spout 27.
In FIG. 3, I show a second modified spout construction including a
spout body 32 extending from the flat top 13. The spout 32
terminates upwardly in a threaded nozzle which is machined or
otherwise treated to provide an external thread 33. A cap 35 closes
the spout 32 and is provided with internal threads 34 to cooperate
with and threadedly engage the nozzle threads 33 to thereby provide
a positive pouring spout closure.
The agitator intermediate portion 50 terminates upwardly in an
integral, bent crank 54 which bends in right angles to the
intermediate portion and lies in a plane parallel with and spaced
above a plane drawn through the top rod section 51. The crank 54
terminates outwardly in an upwardly bent section 55 which is sized
to receive the handle 36 thereon. The handle 36 is axially drilled
to form an axially extending opening 56 which is sized to overfit
the bent section 55 and to be rotatable thereon. Thus, by grasping
the handle 36, the agitator 23 may be conveniently rotated about
the central bearing opening 22 to thus simultaneously rotate the
top rod section 51, the downwardly extending leg 24, the horizontal
leg 25 and the upwardly extending diagonal leg 26 for paint
agitation purposes.
Referring now to FIGS. 5, 6 and 8, a modified type of agitator 23'
is illustrated wherein the intermediate portion 50 terminates
upwardly in a short vertical extension 37. The extension 37 is
provided with means 40 for selectively attaching either a separate
crank handle 38 (see FIG. 6) or an electric hand drill 39 (see FIG.
8) for rotating purposes. The means 40 are illustrated in a square
configuration end to receive the square configuration opening 41 of
the crank handle 38 for agitator rotation purposes. A set screw may
or may not be included for securing the crank handle 38 to the
vertical extension 37. To render the device operable by power
operation, a tool 42 of usual design for rotation by a usual
electric power drill 39 is provided having a socket 43 of square
configuration of size and dimensions to closely overfit the square
configured end 40 of the vertical extension 37. THus, the socket 43
may position over the square configuration end 40 for power
rotation of the agitator 23 in the usual manner through a
conventional speed reduction mechanism (not shown).
If desired, as illustrated in FIG. 7, the intermediate portion 50
may terminate upwardly in a short cylindrically configured terminal
end 46 which is machined to provide a flat surface 47 for operation
with the modified crank handle 45. The crank handle 45 is machined
at one end thereof to provide a cylindrical opening 44 to therein
receive the cylindrically configured terminal 46. A threaded
opening 49 horizontally communicates with the cylindrical opening
44 and receives a thumb set screw 48 in threaded engagement
therein. The thumb screw 48 serves to rigidly secure the crank
handle 45 to the cylindrical terminal end 46 by engaging the thumb
screw 48 onto the flat surface 47. A crank handle 36 upwardly
projects from the opposite side of the crank in the usual rotative
manner to provide a grasping handle for agitator rotative
purposes.
It is of course to be understood that an electrical power drill 39
may be chucked directly to the end of the vertical extension 37 if
high speed agitator rotation is desired.
It will be noted that the present construction as illustrated in
FIGS. 5-8 permits this device to be packaged with the crank handle
disassembled to thus allow the agitator 23 to be removed from the
lid 12. Thus, the device can be easily packaged as a small, compact
unit.
In operation, the combined paint can agitator and pouring top is
designed for use with the usual 1 gallon paint container as
normally purchased. The conventional lid (not shown) of the usual
paint container should be removed and stored for later clean
replacement to reseal unused liquid container contents after use of
the device. After removal of the container lid (not shown), the lid
12 mounts upon the container 17 with the downwardly extending
flange 15 positioned over the exterior top of the container. The
annular lip 18 circularly fits into the usual top paint container
groove and combines with the flange 15 to provide a liquid tight
seal between the paint container 17 and the assembly 11. With the
paint can agitator and pouring top 10 positioned as illustrated in
FIGS. 1 and 4, the liquid contents can be stirred quickly and
completely by rotating the crank handle 36 to easily stir and
agitate all of the container contents. It should be noted, that the
intermediate portion 50 of the agitator 23 extends high enough to
permit the bent crank 54 to clear the top of the pouring spouts 19
during the stirring operation.
After completion of the necessary paint agitation, the lid 12
remains upon the top of the paint container 17 and both caps 20 are
removed from their respective associated pouring spouts 19. With
the liquid contents thoroughly agitated and the caps 20 removed,
the paint container 17 can then be tilted with one of the spouts 19
in a lower position and the other of said spouts in an upper
position. With the container thus tilted, the liquid contents will
flow outwardly from the lower spouts. It will be evident that
during the pouring process air will enter the interior of the
container through the upper spout which then serves as a readily
accessible vent. The paint pouring operation will thus be neater,
smoother and offer less chance of paint spilling to greatly improve
over prior art practices. It will also be noted that the circular
lip 18 completely seals the upper paint container groove about the
access opening to thereby prevent paint from entering the groove.
It is contemplated that all paint required for the painting
operation will be taken from the second container into which the
contents of the container 17 are poured. Upon completion of the
painting operation, the paint can agitator and pouring top 10
should then be removed from the paint container 17 and cleaned and
stored for future re-use. With the access opening of the container
17 thus exposed, any paint remaining in the second container can
then be poured back into the container 17. The lid (not shown) can
then be re-installed to reseal the paint container 17.
