Claims
What is claimed is:
1. A protective apron for use over the opening of a container,
comprising:
a vertically-disposed internal portion having a central
opening;
a mid-portion, integrally formed with said internal portion, for
disposal over the rim of the container;
an annular rim disposed below said mid-portion, for frictionally
engaging the rim of the container; and
an external portion, comprising a downwardly sloping,
conically-shaped surface coupled to said mid-portion, said surface
providing a protective hood over the side walls of the container,
and an upwardly extending flange joined to the edge of said
conically-shaped surface for forming an annular catch basin for the
contents of the container.
2. The protective apron as recited in claim 1 wherein said external
portion further comprises an extending annular finger for
engagement with the side walls of the container.
3. The protective apron as recited in claim 1, wherein said
conically-shaped surface coupled to said mid-portion comprises an
annular ring-shaped flange, affixed at one end to said mid-portion,
and disposed at an obtuse angle with respect thereto, for providing
a downwardly and radially outwardly extending annular surface
around the opening of the container.
4. The protective apron as recited in claim 3, wherein said
upwardly extending flange comprises a conically-shaped, upwardly
and radially outwardly extending annular ring-shaped flange,
affixed at one end to the end of said annular flange affixed to
said mid-portion, said downwardly and upwardly extending flanges
forming a substantially L-shaped annular catch basin disposed at an
angle with respect to the side of the container on which it is
disposed.
Description
This invention relates to a protective apron for use with a
container.
More specifically, this invention relates to a protective apron
which can be placed over or coupled to the top rim of an opened
paint can.
In applications where paint is applied to surfaces with a brush
which is dipped into a paint can, it has been found that the paint
fills in the top rim of the paint can and also partially covers its
outside label or surface. It therefore becomes difficult for the
user to properly replace and secure the lid to the paint can, or
identify its contents from the label which becomes partially
covered with paint.
In order to overcome the above described disadvantages, several
conventional devices have been utilized which consist of funnel
shaped members which are inserted onto the top rim of the paint can
so as to enlarge the can opening and provide a surface for wiping
the brush during the painting process. Since many of these
conventional devices only partially fit into the rim of the paint
can, paint has still been found to contaminate the internally
exposed edge of the rim which serves to retain the funnel-shaped
device in place.
Accordingly, the present invention provides a protective apron
which overcomes many of the disadvantages of conventional type
devices in covering over the entire top rim of the paint can or
other type of container, and further provides a portion which
partially extends into the internal part of the can. The apron of
the invention also extends downwardly over the outside of the can
to serve as a hood or shield to prevent paint or other contents in
the can from contacting the external surfaces. The external portion
of the apron also includes a catch basin or well which serves as a
reservoir for catching any of the contents of the can which flow
across the outside surfaces of the apron. The external portion of
the apron thus holds any paint on its periphery while its internal
portion drains the paint back into the contents of the can.
The protective apron of the invention may be inexpensively
manufactured so that it will be disposable after each use, and can
be provided in a variety of sizes to fit conventional paint cans or
other types of containers.
It is therefore an object according to the present invention to
provide a protective apron for a container which mounts to the
opening of the container to permit its contents to be either
drained back into the container or be collected along the
apron.
It is another object according to the present invention to provide
a protective apron for a paint can which is disposable after each
use.
It is still a further object according to the present invention to
provide a protective apron for paint cans which is simple in
design, easy to manufacture and reliable in operation.
Other objects and features of the present invention will become
apparent from the following detailed description considered in
connection with the accompanying drawings which disclose the
embodiments of the invention. It is to be understood, however, that
the drawings are designed for the purpose of illustration only, and
not as a definition of the limits of the invention.
In the drawings, wherein similar reference characters denote
similar elements throughout the several views:
FIG. 1 is a perspective view of the protective apron according to
the invention.
FIG. 2 is a cross-sectional view taken along section 2--2 of FIG.
1.
FIG. 3 is a further cross-sectional view of an additional
embodiment of the invention.
Referring to FIGS. 1-3, there is shown a container 10 which is
preferably a cylindrically shaped paint can having its lid removed
to expose its top or opening and contents 11. The top or opening of
container 10 is surrounded by a U-shaped rim 12, and an upwardly
extending external flange 13 as shown in detail in FIGS. 2 and 3.
Inserted into U-shaped rim 12 is the protective apron according to
the invention consisting of a vertical internal portion 17 which is
open to contents 11 within container 10, and mid portion 16 which
in one embodiment includes an annular rib 19 for engagement into
U-shaped rim 12. The protective apron according to the invention
further includes a conically-shaped downwardly sloping external
portion 15 which forms an annular catchbasin by its connection with
upwardly sloping flange 14.
The protective apron is preferably constructed from a single piece
of material such as plastic, metal and the like, and is designed to
be disposable after each use. Mid portion 16 of the apron not only
completely covers over the rim of container 10 but also serves as
shown in FIG. 2 as a detachable connector through the use of its
annular rib portion 19, engaging into U-shaped rim 12.
Referring to FIG. 3, there is shown another embodiment of the
present invention wherein annular rib portion 19 has been omitted
from mid portion 16 since the mid portion, and internal portion 17
firmly engage rim 12 of can 10. It is also not necessary to include
the annular extending finger 18 in this embodiment. An additional
embodiment taken from that shown in FIG. 3 may also include annular
extending finger 18 disposed below mid portion 16 and urged along
the bottom surface of flange 13 so as to further retain the
protective apron on to the top of the can. Extending finger 18 is
curved backwards, away from the opening of the can to permit it to
be easily inserted over flange 13 when the protective apron is
mounted on to the top of the container.
In actual use, a receptacle such as a paint brush can be inserted
into the central opening of internal portion 17 and into contents
11, and can then be wiped against its vertical wall surface to
remove the excess paint. None of contents 11, such as paint, can
contaminate the rim or sidewalls of container 10 due to mid portion
16 and external portions 15 and 14 of the protective apron. Any of
the paint which flows outside of internal portion 17 will be
retained within the annular well or basin formed by portions 15 and
14 so that it can be reused.
The protective apron according to the invention has been known to
be highly successful in protecting the rim and sidewalls of
containers. In painting operations, the protective apron has been
found to greatly reduce the wasting of paint which normally occurs
with conventional types of paint aprons and with containers not
having any types of aprons.
While only a few embodiments of the present invention have been
shown and described, it will be understood that many changes and
modifications may be made thereunto without departing from the
spirit and scope of the invention.
