RIM PROTECTOR AND PAINTING IMPLEMENT CONTAINER FOR PAINT CANS
Abstract
A plastic ring is provided at its outer edge with a flange or
other clamping means to fit over and to attach securely to the
circular rim of an open paint can. The clamping means serves to
hold the ring securely in place by tightly engaging the exterior
side wall of the paint can at the rim, and yet allows the ring to
be readily removed from the can. The open center of the ring is of
sufficient dimensions to permit the dipping of a brush into the
paint in the can while the ring is attached. At least a portion of
the inner edge of the ring defining this open center provides a
scraping edge for removing excess paint from the brush. A small
container for holding the brush in upright position is retained
against the exterior side wall of the can by an arm secured to the
clamping means. A screen is mounted in and at least slightly above
the bottom wall of the container to act as a resting surface for
the tip of the brush while in use, to allow excess paint to drip
free thereof.

Description
This invention relates to a detachable rim protector for paint
cans, in combination with a container for holding paint brushes or
other implements.
In the past, various painting aids have been proposed for use with
paint cans for the ease and convenience of the painter. In one such
proposal, a ring member adapted to be fitted over the mouth of an
open paint can is provided with a striker bar for cleansing a paint
brush over the mouth of the can. One configuration of this type of
device is a ring having a bar extending between the sides of the
ring over the mouth of the can to allow a paint brush to be stroked
against the bar to drip excess paint back into the can. Another
prior art type of striker blade includes an extended portion of the
lip of the ring itself which reaches over the opening of the
can.
The purpose of these painting aids is to prevent the use of the rim
itself as a convenient stroking edge to remove excess from the
brush, because that practice would result in a buildup of paint in
the rim sealing channel. When such a buildup occurs, it becomes
quite difficult to obtain a tight reseal of the paint can lid upon
completion of the job, without first cleaning out the channel. The
cleanup job itself can be quite tedious, particularly if the paint
in the rim channel has dried or caked. A further problem
encountered in use of the rim itself as a stroking edge is that as
the rim channel fills, the paint drips down the side of the
can.
The prior art painting aids of the aforementioned type have been
generally unsuitable for accomplishing the desirable purpose of
preventing the clogging of the rim channel and spillover of paint
down the side of the can. Usually only a relatively small striker
blade or bar is provided, and depending on the position of the
painter relative to his paint can, he may often find it more
comfortable to use the rim rather than awkwardly reach around to
draw the brush against the bar, or change the position of the paint
can.
Another paint can feature which has been proposed as a convenience
to the painter is the provision on the can of a clamping or
gripping device for holding the brush on those occasions when the
painter desires to set down his brush. The principal purpose of
such devices is to hold the brush in position which allows wet
paint to drip from the bristles, back into the paint can, and which
permits convenient grasping of the brush handle when the painting
is continued. Otherwise, the brush is usually simply laid flat on
the rim of the can, leading to clogging of the rim channel and
dripping of paint along the side of the can or on the surface on
which the can rests. Another frequent practice of the painter is to
avoid the paint can when the brush is to be set down, and instead
to lay the wet brush flat on a paper or cloth covering the surface
to be protected. Of course, if the brush holds an abundance of
paint when it is laid down in that manner, the paper or cloth may
absorb enough paint to allow it to mar the surface to be protected.
At the very least, the latter practice leaves a wet paint spot
which is all too often stepped on or leaned on to cause the paint
to be undesirably transferred to other surfaces or items.
Nevertheless, the gripping devices provided in the past have been
vastly unsuitable. By their very nature such devices have usually
required the painter to use his free hand to open the clip or clamp
while placing the brush therein or removing the brush therefrom.
This may lead to losing the grip on the brush before it has been
secured or removed, allowing it to fall into the paint can, onto
the floor, or onto any other surface over which it is disposed.
Furthermore, since the gripping device is usually arranged to
retain the brush with the bristles disposed over the mouth of the
can, the device must project from the can itself and is subject to
being accidentally struck which could cause overturning of the
can.
The present invention provides a useful adjunct for paint cans,
which avoids the limitations and disadvantages noted above with
respect to the prior art aids, while accomplishing their desirable
goals. Briefly, according to a preferred embodiment of the
invention, a circular ring-shaped member has a flange portion at
its outer edge to permit attachment over the mouth of a paint can.
The central opening of the ring is of sufficient dimension to
permit a brush to be dipped into the open can. The ring itself
covers the rim of the can entirely, and at least a portion of the
inner edge of the ring provides a stroking edge against which to
draw the side of the brush to remove excess paint when the brush is
withdrawn from the opening. This configuration ensures that the rim
channel is completely protected against entry of paint therein,
regardless of the extent of any specific stroking edge on the ring
and regardless of the orientation of that stroking edge relative to
the position of the painter.
An open container is secured to the ring against the side of the
can. A screen is mounted in the open container, but spaced somewhat
from the bottom wall thereof, to provide a surface against which
the tip of the bristle portion of the brush may rest when not in
use, while allowing wet paint to drip free of the brush and into
the bottom of the container. Since the brush is held in the
container in a substantially upright (i.e., vertical) position, any
wet paint in the brush does have the tendency to drip toward the
tip of the bristles, and ultimately, free of the brush, rather than
to be retained on the bristles (particularly at the base thereof)
as would be the case if the brush were held in a horizontal
position. Furthermore, because the side of the brush rests against
the side of the open container, there is no need to employ gripping
or clamping devices, and the handle of the brush is readily grasped
for re-use without releasing any gripping members.
Accordingly to the preferred embodiment, the open container is
tapered to permit several such containers to be stacked together in
a mating compact arrangement for shipping, storage and display
purposes. In addition, the open container is preferably not
permanently attached to the ring, but may be temporarily securely
fastened thereto while in use on the paint can.
The above and still further objects, features and advantages of the
invention will be better understood by reference to the following
detailed description, in conjunction with the accompanying

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
with reference now to FIGS. 1-3 of the accompanying drawings, a
first embodiment of the painting aid of the present invention,
generally designated by reference numeral 10, is employed in
conjunction with a paint can 11. This embodiment is constructed and
arranged for use with a paint can 11 having a cylindrical side wall
12 (FIG. 3) with a rim portion 13 that projects radially toward the
axis of the paint can from the upper surface of the cylindrical
side wall. In this type of paint can, the rim has a downwardly
extending circular channel or groove 14 adapted to accept a mating
tongue on the lid or cover (not shown) of the can for sealing the
contents of the can from the outer atmosphere.
Painting aid 10 of FIGS. 1-3 comprises a first member 15 having a
generally ring-like configuration, the outer periphery of which has
a diameter approximately equal to that of the diameter of paint can
11, to provide a tight fit with the outer edge of the rim 13 as
will presently be clear. Projecting perpendicularly (downwardly
relative to the base of the paint can) from this outer periphery of
ring 15 is a flange or lip 16 which is intended to clamp onto the
outer edge of rim 13 (i.e., adjacent the side wall 12 of the paint
can 11) in tight fitting frictional relationship when the ring 15
is aligned with and is pushed down over the top of the can. In this
respect, it should be observed that the painting aid 10 will
generally be utilized in position on the paint can after the can
has been opened to expose the paint inside. Thus, since the lid has
been removed from the can, access to the contents of the can is
available via the hole 17 defined by the inner edge of ring 15.
At least a portion of this inner edge of ring 15 is in the form of
a preferably straight-edged plate 18 against which the side of a
paint brush may be drawn or stroked as the brush is withdrawn from
the can after being dipped into the paint therein. The straight
edge of plate 18 provides greater assurance that the excess paint
in the brush (i.e., that amount of paint which is desired to be
removed before applying the brush to the surface to be painted) is
uniformly removed from the brush rather than merely removing excess
paint from the edges of the brush and leaving the middle portion of
the brush relatively untouched, as usually occurs when the brush is
drawn against a round edge. Preferably, plate 18 has a bar portion
19 extending downwardly at a slight angle therefrom to provide the
stroking edge against which the wet brush is to be drawn. The
inclined surface of bar portion 19 insures that should any paint
accumulate on or near the straight stroking edge, it will tend to
run back into the can along the inclined surface of bar 19, rather
than to further accumulate along the top surface of plate 18 and
eventually drip down the exterior side wall of the can. Moreover,
the width of ring 15 is sufficiently greater than the width of rim
13 such that the rim is completely covered by the ring. Hence, in
the event that the brush should be drawn against the inner edge of
ring 15 rather than against the straight edge of bar 19, the
sealing channel 14 of the rim is protected against entry of any
paint therein.
According to a further aspect of the invention, painting aid 10
also comprises a container 20 for holding and/or storing painting
implements such as brushes and scrapers. It is contemplated that
container 20 will typically be limited to holding a wet brush or
brushes during an actual painting operation, to prevent wet paint
from being transferred to other painting implements. However, the
container is useful for storing a variety of implements at close
hand to the paint can when the can is being stored between painting
operations. In any event, container 20 is secured to the ring
member 15, preferably by means of an arm 21 which projects upwardly
from the upper lip of the container as an extension of the side
wall thereof. Arm 21 is provided at its free end with a hook 22
which is adapted to be received within a hole 23 in an arm 24 that
extends downwardly from ring member 15 as an extension of flange
16. When arms 21 and 24 have been aligned, and hook 22 has been
inserted into hole 23, the hook may be brought over the edge of arm
24 at the hole as a catch to secure the container 20 to ring member
15. Typically, this attachment of the container to the ring member
will be performed prior to attaching the ring to the paint can.
Thus, when the ring member 15 is in position on the paint can, the
container 20 is secured in position directly against the exterior
side wall of the paint can. To assure a snug fit of container 20
against the cylindrical side wall of the can, wall 25 of container
20 may have a concave contour conforming to the cylindrical contour
of the side wall of the paint can.
Since the container 20 is secured to ring member 15, and the ring
member 15 is in turn attached to the paint can, a wet brush 26 may
be conveniently rested in virtually upright position in the
container (i.e., supported against the side of the container) to
hold it close at hand during a painting operation, and to allow any
excess paint to drip free of the brush and into the bottom of
container 20. In order to prevent the accumulation of wet paint at
the tip of the brush while it is resting in upright position in
container 20, which would tend to cause clogging of the tip of the
brush with partially drying paint, a screen mesh or grate 28 is
fastened in container 20 above the bottom well 29 of the container
and generally parallel thereto. Preferably, this screen 28 is
removable from container 20 to permit easy access to the bottom of
the container so that paint may readily be removed therefrom after
the painting operation has been completed. In addition, if the
screen 28 is removable, it may readily be cleaned in a cleaning
fluid of a type that will depend upon the nature of the paint which
has been used. For that purpose, screen 28 closely conforms in
shape to the interior contour of the container 20, for relatively
tight fit therewith, and rests on a ledge or shelf 30 formed along
the interior wall of the container.
Preferably both ring member 15 and container 20, and their
associated parts, are composed of a relatively flexible plastic
material for light weight and for ease of assembly and attachment
to the can. In addition, the side wall of container 20 may be
tapered from a wider dimension at the top or open part thereof to a
narrower dimension at the bottom, as shown in FIG. 4, to permit the
containers to be stored one within another during shipping,
storage, and/or marketing of the containers.
With reference to the container 35 in the painting aid embodiment
shown in FIG. 4, the entire side wall 36 is tapered in the
aforementioned manner except for that portion 37 to be disposed
immediately adjacent the side wall of the paint can. This insures
that container 35 is perfectly stable as it rest in direct contact
with and against the can, and yet permits a multiplicity of such
containers to be stacked together, one within another.
In the embodiment of FIG. 4, a second technique of securing the
container to the ring member 15 is shown. According to that
technique, an arm 38 which projects upwardly from container 35 as
an extension of side wall portion 37 is secured frictionally
between the outer edge of the rim of the paint can and the inner
surface of the flange or lip 16 of the ring member 15. Of course,
any desired technique of securing the ring member to the container
may be utilized. However, where the technique depends entirely on
frictional clamping, as in the embodiment of FIG. 4, it is
desirable that arm 38 be sufficiently long to allow the bottom of
the container to be aligned with the base of the paint can, so that
both may rest on the same surface. This provides additional
protection against the possibilities of the container being
accidentally forced or jarred loose from securement with the ring
member 15, after the painting aid has been attached to the paint
can. However, it is to be understood that in any of the embodiments
of the present invention the base of the painting implement
container may be disposed above the base of the paint can, if
desired, when the entire painting aid is assembled and fastened
into position on the paint can. Such an arrangement is shown, for
example, in FIG. 1.
In use of the embodiments of FIGS. 1-4, after the lid has been
removed from a new can of paint the painting aid 10 is attached to
the can. In the embodiment of FIGS. 1-3, members 15 and 20 may be
fastened together before attachment to the can. Thereafter, the
ring member 15 is placed over the rim 13 of the can and pressed
down so that the flange 16 is forced over and is tightly clamped
about the outer edge of rim 13 and/or the upper part of the
cylindrical side wall 12 of the can. The container 20 is maintained
in snug position against the side wall of can 11, by virtue of the
connection between the ring member and the container. In the
embodiment of FIG. 4, the arm 38 is placed against the side wall of
paint can with the free end of the arm virtually even with the
upper edge of the side wall of the can. Then the ring member is
slipped over the rim of the open paint can with sufficient force to
secure arm 38 in position under flange 16.
With regard to each of the embodiments of the invention thus far
described, it is to be understood that the ring member and the
container may be permanently fastened together in any desired
manner, such as by heat sealing thereof, rather than being separate
attachable members. However, the separate components are preferred,
because of the ease of packaging, shipping, and storing such
components in comparison to permanently attached members.
With reference now to FIG. 5, the embodiment there shown is adapted
for use with the type of paint can in which the rim portion is a
completely cylindrical configuration and is slightly smaller in
diameter than the side wall of the paint can. That is to say, the
cylindrical rim is stepped slightly back from the cylindrical side
wall of the can. The cover for such a paint can typically has a
flange or lip extending perpendicularly from the outer edge of the
lid portion. This flange is split at several points to facilitate
removal from and attachment to the can. In addition, a clamping
ring is usually provided, for placement over the cover when in
position on the can, to lock the cover tightly in place. In the
embodiment of FIG FIG. 5, therefore, the ring member 40 has a
curved flange portion 41 to permit the flange to be secured to the
exterior side wall of the paint can, and yet to curl over the
upwardly projecting, smaller diameter cylindrical rim. The interior
portion of ring member 40 is inclined downwardly toward the center
of the can to permit paint which accumulates thereon when a brush
is drawn against its cylindrical edge 42, to drip back into the
can. This inner edge 42 is split or serrated to facilitate the
manufacture of the ring and to allow the central portion thereof to
be inclined downwardly without placing undesirable stresses along
inner edge 42. As in the previous embodiments, the ring member is
retained by virtue of the tight fit between its flange and the top
of the exterior side wall (or the rim) of the paint can. Also, the
container 45 may be permanently fastened to the ring member 40 or
may be a separable component of the overall painting aid.
In the embodiment of FIG. 6, a multicompartmented container 48 is
separately fastened to ring member 40 at two (or more) arms 49, 50,
in the same manner as is shown for the embodiment of FIGS. 1-3. The
ring member has the configuration of the embodiment of FIG. 5, and
the container 48 encircles the entire paint can. The multiplicity
of compartments, e.g., 51, 52, 53, are separated by partitions,
e.g., 54, 55, respectively, and permit the retention of a
substantially larger number of painting implements, including
brushes, in readily accessible array about the open paint can. This
embodiment of the painting aid is readily attached to the paint can
by first inserting the base of the can into the central opening in
container 48. Such placement circumvents the need for any special
arrangement to allow the sockets 57 for the handle 58 of the paint
can to slide past the interior side wall of container 48, provided
the container is not of such depth as to extend beyond the handle
sockets. The container 48 is readily attached to ring member 40,
after the base of the paint can has been placed in the central
opening, because the downwardly extending arms on ring member 40
are composed of flexible plastic and may be easily brought under
the hooks on the outwardly extending arms of container 48.
Another embodiment of the invention having a multicompartmented
container is shown in FIG. 7. Referring to the latter FIGURE, the
container 60 is permanently fastened to a ring member 61 having the
general configuration of the embodiment of FIGS. 1-3. In the
embodiment of FIG. 7, this permanent attachment is conveniently
made by extending the flange portion 62 of ring member 61 to
constitute the interior side wall of the compartmented container,
and heat sealing the interior edges of the partitions 63 to flange
62. Oppositely disposed channels 64 and 65 on the container are
provided with open bottom areas to permit the container and the
ring member to slide over the handle sockets when the painting aid
is placed into position on the open paint can, after the handle 66
has been temporarily removed from the sockets. After the painting
aid has been attached to the can, the handle is readily replaced in
the sockets to permit the can to be conveniently carried from one
place to another. As in the previous container embodiments, the
containers of FIGS. 6 and 7 are provided with screens spaced from
the bottom of the container. While a relatively shallow container
is shown in FIG. 7, it is to be understood that the container may
be of any desired depth in practice, up to the depth of the paint
can itself.
While certain preferred embodiments of the present invention have
been disclosed, it will be appreciated that modifications and
variations of the specific details of construction which have been
illustrated and described may be resorted to, after consideration
of the above disclosure, without departing from the spirit and
scope of the invention, as defined in the following claims.
