Attachment for grooved-rimmed containers
Abstract
A slightly undersized snap-fitting integrally formed attachment
for grooved-rimmed containers comprises an annular ring which has
furrows or grooves formed therein. The grooves mate with the beads
of the rim of such containers. Integrally formed on the ring is a
tab for facilitating easy removal of the attachment from the
container. Also integrally formed on the ring is a projecting
member. The projecting member comprises two inwardly projecting
parts, the spacing between the two parts defining a slot and a slit
which extends into the slot. The slot is sized and shaped so that
when a conventional stirring stick is inserted in the slot through
the slit, the slot will frictionally hold the stick. The edges of
the slot also serve to squeegee the stick when the stick is drawn
therethrough.

Description
This invention relates to attachments for grooved rimmed containers
such as paint, varnish and shellac cans and the like; and more
particularly, to annular attachments which are adapted to be
readily mounted on and detached from the rim of such
containers.
Persons familiar with the handling of grooved rimmed containers
which contain paints, varnishes, shellacs and the like, are aware
that when such containers are opened it is usually desirable, and
often times necessary, to stir the contents of the container with a
conventional stirring stick. This process usually poses several
problems in terms of avoiding overflow, spilling and messiness.
Most conventional containers are equipped with a detachable lid
having a friction rib keyed in a channel or groove of the annular
rim. By way of example, if the container is a paint can, when the
can is opened and the paint is stirred with a stirring stick, paint
may spill into the channel of the rim. Secondly, when the stirring
operation is completed, many people will draw the stirring stick
against the holding rim in order not to remove the excess paint
from the stirring stick, and thus avoid waste but also to clean the
stick as much as possible in order to avoid a mess when it is put
down after using it to stir the paint. As a result, when the can is
being used, the stirring stick will pose a problem in that it will
be wet from excess paint.
Attachments for grooved-rimmed containers with paint brush wipers
are known such as shown in U.S. Pat. Nos. 2,873,052 and 2,960,257,
and attachments for grooved rimmed containers having paint brush
holders secured to the attachment by screws are known as shown in
U.S. Pat. Nos. 3,016,169 and 3,168,962.
Until the present invention, however, no one has satisfactorily
made an integrally-formed attachment which will keep the channels
of grooved-rimmed containers dry when the containers are being used
as well as hold a conventional painting accessory such as a
stirring stick to allow the excess paint to drip into the can when
the stick is being held and also act as a squeegee when the stick
is drawn through the holding portion of the attachment.
It is therefore, an object of the present invention to provide a
simple, practical, economic can attachment which can be readily
applied and removed, and which enables the user to overcome the
aforementioned problems.
It is another object of the present invention to provide an
integrally-formed attachment for covering the channel of the rim of
the type of containers described herein, and for receiving and
holding a painting accessory.
Still another object of the present invention is to provide an
attachment for grooved-rimmed containers having an annular portion
for protecting the channels when the containers are being used and
having integrally formed on the annular portion, a projecting
member having a slot for receiving and holding a conventional
stirring stick, and functioning as a squeegee for effectively and
efficiently removing the excess material from the stick when the
stick is drawn through the slot.
Yet another object of the present invention is to provide an
attachment for grooved-rimmed containers with a snap fit to provide
a snug fit over the channels of the containers to provide a better
seal and prevent the attachment from slipping off.
Still another object of the present invention is to provide an
attachment which can be easily attached and removed.
Generally, the foregoing and other objects are realized by a
slightly undersized integrally formed attachment which comprises an
annular ring portion formed of requisite size, shape and resilient
material, e.g., rubber or any suitable moldable plastic material.
The annular portion has a channel-type adapter, the flanges or
walls of which aptly and fittingly apply themselves and provide the
desired sealing result. Integrally attached to the annular portion
and projectng therefrom is a member having a slot formed therein.
The slot is of requisite size and shape in order to frictionally
hold a conventional painting accessory such as a stirring stick.
The slot can be designed in such a way as to hold the stick and to
function as a squeegee when the stick is drawn therethrough.
Other objects of the present invention will in part be obvious and
in part will appear hereinafter. The invention accordingly
comprises the article of manufacture possessing the construction,
combination of elements, and arrangement of parts which are
exemplified in the following detailed disclosure, and the scope of
the application of which will be indicated in the attached
claims.
For a fuller understanding of the nature and objects of the present
invention, reference should be had to the following detailed
description taken in connection with the accompanying drawings
wherein:
FIG. 1 is a top plan view of the attachment for attachment to a
conventional grooved-rimmed container; and
FIG. 2 is an enlarged sectional view taken on the plane of the
section line 2 -- 2 of FIG. 1, including a cross-sectional portion
of the rim of a container;
FIG. 3 is an enlarged sectional view of another embodiment of the
invention, showing it fitted to a cross-sectional portion of the
rim of a container.
Referring in detail to the drawing, wherein like and related
numerals designate like and related parts throughout the several
views, a conventional container 10 such as the type used to store
paints, varnishes, shellacs and the like is shown having an open
end with a circumferential rim 12. The rim 12 usually comprises a
sheet metal annular body clamped to the upper edge of the container
side wall 14 to form outer bead 20. The rim 12 of the conventional
container further comprises channel 22 defined by a side wall 24,
an inwardly extending annular horizontal ledge 26 at the lower end
of side wall 24, a gutter 28 which is formed by side wall 29 which
extends down from the inner edge of the inner ledge 26, the bottom
inner extending flange 30, the inner side wall 31 which terminates
at horizontal ledge 32. Side wall 33 extends above ledge 32 and
terminates wherein inner bead 34 is formed. The usual paint can
cover (not shown) has depending annular portions which frictionally
engage with the rim 12.
When the contents such as paint is stirred and poured from
container 10, it is usually difficult if not impossible to prevent
some of the paint from spilling into and accumulating in channel
22.
The attachment 40 comprises a preferably solid, integral,
monolithic, flexible and resilient annular non-metallic portion
which has a substantially flat horizontal center portion 42 and
inner and outer rim portions 44 and 46, respectively. The rim
portions are formed in such a manner as to provide furrows or
grooves which are generally spaced from each other by said center
portion 42 and are of such size and shape so as to mate with the
inner and outer beads 34 and 20 respectively as shown best in FIG.
2. The ends of rim portions 44 and 46 are drawn slightly inward
toward center portion 42 as shown at 48 in the drawings, in order
that the attachment 40 may snap-fit onto the rim. The annular
portion attachment 40 is made slightly smaller in diameter than the
diameter of the container rim, so that as a result of its
resiliency and flexibility, the annular attachment can be
resiliently stretched onto the rim and mate with the corresponding
surfaces as shown. This results in a good seal of the channel 22 as
well as a tight fit preventing the attachment from slipping
off.
An additional feature of the attachment 40 is projecting member 50,
which is made of the same material as the annular portion, is
integrally attached thereto and which is composed of two parts 52
and 54.
Parts 52 and 54 are formed so as to provide slot 56 in between. By
way of example, the slot is dimensioned so as to accommodate the
conventional stirring stick, such as 11/4 by 1/8.
A space or slit 58 between the end portions of parts 52 and 54 is
provided in order to facilitate insertion of the stirring stick
into slot 56 and to aid in the prevention of damage to parts 52 and
54 due to stresses thereon when the stirring stick is inserted and
drawn therethrough.
A tab 60 is also integrally formed on the outside of the annular
portion of attachment 40 to facilitate easy removal of the
attachment from container 10, after the contents have been used,
and the user wishes to replace the lid.
The annular portion of the attachment 40 as shown in FIG. 2 may be
modified as shown in FIG. 3. The attachment 70 in FIG. 3 has an
inclined surface 72 to enable excess paint to run off and spill
back into container 10. Attachment 70 has sides 74 and 76 which are
formed to snap fit over beads 20 and 34 respectively insuring the
seal of channel 22.
While a particular embodiment of the attachment has been described,
it will be understood that various changes and modifications may be
made from the foregoing without departing from the spirit and scope
of the appended claims.
