Description
BRIEF SUMMARY OF THE INVENTION
The objective of this invention is to provide a can or container
with an exterior rim adjacent the upper open end of the container
which can be closed by a cover or lid which is resealable to permit
repeated covering and uncovering of the container so that it can be
used repeatedly, and in which the rim is integrally formed with
locking lugs which are bent to secure the cover to the container
and which may be unbent to permit removal of the cover or lid. The
container has a body shaped so that it can be stacked with other
like containers in a telescopic or nested relationship to occupy a
minimum of shipping and storage space.
Another object of this invention is to provide a metal or plastic
container formed with a separate rim which is attached adjacent the
upper open end of the container exteriorly thereof and so
constructed that no portion of the rim extends within the container
so that there is no interference with the upper edge of the
container and this permits the containers to be telescoped or
nested one within the other for storage and shipment.

FIG. 8 is a modified rim.
The can or container generally indicated at 10 is formed preferably
of metal and comprises a cylindrical body 12 closed at the bottom
thereof with a bottom 14. The cylindrical body 12 has a slight
inward taper from the top toward the bottom so that the smallest
diameter or circumference of the container is at the bottom and the
largest at the top. This tapering body permits the containers to be
stacked and nested one within the other, best seen in FIG. 4, to
occupy a minimum of storage and shipment space. The upper portion
of the container is open and is adapted to be closed by the cover
generally indicated at 16, to be hereinafter described.
The cylindrical body of the container adjacent the top thereof has
an inwardly offset annular wall portion 18 which at the lower end
defines a continuous annular shoulder 20. The upper end or mouth of
the container has an outwardly and downwardly turned flange 22
which is spaced from the wall 18 and which defines an inverted
U-shaped top edge 23 which is adapted to receive and retain
therebetween the upper portion of the rim, presently to be
described.
The rim forming this invention is generally designated at 24 and is
formed from a strip of flat stock of sheet metal material and from
the initial flat strip is preshaped or stamped to the configuration
shown in FIG. 5 and then when applied to the container is shaped to
form the annular strip or rim 24. The rim 24 comprises an
intermediate body portion 26 which is curved inwardly as at 28 at
its lower end to form an inwardly extending bottom generally
horizontal wall 30 and then reversely curved as at 32 and continues
downwardly to form a lower vertical wall 34 and is then curved
upwardly to form a bottom lip 36.
The upper portion of the intermediate body portion 26 of the rim 24
is then reversely bent as at 37 to form a downwardly extending
short vertical wall 38 positioned contiguous to the front upwardly
extending portion and then continues inwardly to form a horizontal
wall 39 which then continues upwardly to form the upper end wall
portion 40 of the rim. The upper portion of the intermediate body
portion 26 and the reversely bent portion 37 form a continuous
outer annular top bead 41 of the rim, best seen in FIG. 6.
At spaced intervals and extending upwardly of the outer annular top
bead 41 are upstanding locking lugs 42, best seen in FIGS. 2, 3 and
5, which are formed from the upwardly extending wall portion of the
intermediate body portion and the reversely bent portion 37
contiguous thereto. The locking lugs 42 are the portions which
extend above the annular top bead 41 and said locking lugs are each
shaped so that they have a peak shape in that the opposite sides
42a of the lugs slope upwardly and inwardly toward the top central
portion 42b which is rounded. The intermediate body portion 26 is
therefore offset from the upper and lower end walls 40 and 34 of
the rim. The rim 24 is formed separately from the container and may
be of less expensive steel or material than that of the
container.
The annular rim 24 is secured to the container body with the upper
portion 40 of the rim received in the inverted U-shaped top edge 23
of the body of the container and with the lower lipped edge 36 of
the rim resting on the shoulder 20. In the formation of the body of
the container, the rim 24 is applied against the upper portion of
the container and then the upper edge of the container is reversely
bent, as seen in FIG. 3, so that the upper portion of the rim would
be confined between said inverted upper edge. The rim 24 will be
retained secured to the upper end of the container by the reversely
turned flange 22 at the upper end when it is crimped against the
upper portion of the rim, however, the rim 24 may be brazed or
otherwise welded in addition thereto to the wall or body of the
container. The rim will thus be positively and permanently secured
to the top portion of the container and, as clearly seen, no
portion of the rim extends within the body of the container so
there is no interference with the open mouth of the container. This
is important from the standpoint of stacking the containers within
each other and also from the standpoint of providing a resealable
cover or lid which is applied to seal the container.
The rim 24 is provided with a pair of diametrically spaced openings
48, as seen in FIG. 1, which receive the hooked ends of the
carrying bail 49 for carrying the container. The carrying bail as
shown in FIG. 1 is in upright or carrying position, however, the
bail may be rotated so that it extends on either side of the rim or
body of the container in an out-of-the-way position. When the rim
24 is secured to the top of the container it is secured in such a
manner that the wall or body of the container forms the top edge 23
or the mouth of the container.
The lid or cover 16 is of circular shape and comprises a main
central concave or dish-shaped portion 50 which continues outwardly
to form a U-shaped bend 52, with the vertical wall 53 of said bend
continuing horizontally as at 54 and then downwardly to form the
outer peripheral flange 55 which provides an inverted U-shaped
configuration generally indicated at 56. The downwardly extending
flange 55 terminates in an outwardly turned edge or peripheral bead
58. A circular gasket 60 which is of an inverted U-shape in
cross-section is positioned inside the U-shaped portion 56 of the
cover and when said cover is positioned on the rolled-over top edge
23 of the container the gasket 60 rests on the rolled-over edge 23
and is interposed between the cover and the rolled-over edge, as
best seen in FIGS. 2 and 3. The beaded peripheral edge 58 of the
cover when the cover is first applied rests adjacent the top
horizontal wall 39 of the rim 24, as best seen in FIG. 3, and
inwardly of the upstanding lugs 42.
To seal the lid 16 to the container, as in FIG. 2, the upper
portion of the upstanding lugs 42 are bent or curved inwardly as at
42' to extend over the peripheral beaded edge 58 of the cover and
this locks the cover in sealing position to the container. The lugs
42 may be bent to the shape 42' in FIG. 2 by any rolling machine or
manually. When the cover is applied to the container it is
foolproof against leakage or the like.
The lid 16 is removable by bending the locking lugs 42 from the
position shown in FIG. 2 to the position shown in FIG. 3 and this
may be done by any conventional tool. The lid may be reapplied to
the container to close the container opening and if it is desired
to reseal and lock the lid the lugs may be manually bent to the
FIG. 2 position. When the lugs 42 are applied to the cover as at
42' they lock the lid or cover to the rim and the top edge of the
lugs are positioned inwardly of the exterior surface of the rim so
that same cannot be accidentally engaged during shipment, as when
containers are positioned contiguous to each other. With the
locking lugs 42 in either locked or unlocked position and the
containers positioned contiguous to each other, the rims 24 of the
containers will be the only portions of the containers which can
engage each other.
There is thus provided a can or container with a resealable cover
which may be repeatedly resealed. Also, by reason of this
construction when one can is nested within the other, the rims of
the nested containers will be as shown in FIG. 4, where the rims
are positioned slightly spaced from each other but superimposed so
that a plurality of containers can be contained in a small area
during transit and storage.
FIG. 7 shows a portion of a rim 24', similar to that of rim 24,
which has a modified locking lug indicated at 62. The locking lug
62 is formed similar to locking lug 42 except that it is not
peak-shaped as is locking lug 42.
FIG. 8 shows a modified rim having the locking lugs 42a similar to
that previously described and in this modification the rim
generally indicated at 24' has the top inner wall portion 40'
turned over as at 64 to overlap the top edge 66 of the container
68, with the turned over edge 64 then crimped to the edge 66.
