glued together. The assembled sheets are pressed
in vsuitable dies to form the‘ bottom proper It 55
and. a flange l5 extendingdownwardly therefrom.
In the application‘ of the bottom to the wall
structure of the container the bottom I2 is in
sertedinto the interior of the container. The
?ange I5 of said bottom is of such dimensions 60
2
2,129,793
as to cause the same to ?t tightlywithin the
lowermost marginal portion H of the wall struc
ture II when the lower edge |8 of said ?ange
is substantially ?ush with the lower edge I! of
the wall structure U. Due to the fact that the
?ange I5 is constructed by bending the mate
rial of the bottom, a rounded corner I6 is formed
between. the bottom- proper l4 and the ?ange
l5. This leaves an’ annular crevice 20 which ex
10 tends about said bottom and which is disposed
between the corner “5 and the wall structure II,
as best shown in Fig. 3.
‘
The hoop I3 is constructed from a straight
narrow strip of sheet metal which is folded Ion-'
15 gitudinally along the center thereof to form a
straight U-shaped structure having two spaced
?anges 2| and 22 connected together through a
rounded connecting portion 23 which when the
hoop is applied to the container,serves as a rim on
20 which the container rests. The straight u-shaped
structure so formed is then run through crimp
ing rolls which engage the ?ange 22 and crimp
the same to form corrugations 24 in said ?ange.
By meansv of this method of construction the
25 length of the ?ange 22 is reduced as compared
to the‘ length of the ?ange 2| and the formerly
straight structure converted into a curved hoop.
Thereafter the ends of the ?anges are secured to
gether as by riveting, soldering or welding to
30 form a hoop of desired dimensions. A portion
' of a. hoop so formed is illustrated in Fig. 4.
In applying the hoop l3 to the container the
lowermost marginal portion I‘! of wall structure
U and the ?ange I5 of bottom l2 are inserted
35 into the space 25 formed between the two ?anges
2| and 22 of said hoop. ' The lower edges I9 and
| 8 of these parts of the container substantially
rest upon theconnecting portion 23 of the hoop.
While the parts are so disposed, scoring rolls
40 are applied to the outer ?ange 2| and‘a punch
ing roll applied to the inner ?ange 22. These
rolls are brought toward one another and as
the bottom structure of the container passes be
tween said rolls the outer ?ange 2| of hoop I3 is
45 formed with two inwardly extending beads 26
and Hand the inner ?ange 22 is formed with
a plurality of barbs 28 which extend toward the
beads 25 and 21. At the same time the margi
nal portion I‘! of wall structure U is formed with
50 grooves 3| and 32 which receive the beads 26
and 21 while the bottom ?ange I5 is formed with
indentations 29' which receive the barbs 28. -By
means of this construction shoulders 34, 35, 36
and 31 are formed in the bottom ?ange l5, and
55 other shoulders 38, 39, 40 and 4| formed in the
marginal portion I‘! of the wall structure 'H,
which engage the ?rst-named shoulders. . These
shoulders serve to restrain relative longitudi
most marginal portion II of the wall structure
II. The rim 23 of the hoop l3 serves as a sup
port for the container proper and also functions
as a skid by means of which the container may
be readily slid upon the surface on which it rests.
With a container constructed in accordance
with my invention the bottom is ?rmly and se
curely held attached to the wall structure. Due
to the rib formed on the wall structure the crev
ice ordinarily existing at the rounded corner be 10
tween the wall structure, bottom and bottom
flange is practically ?lled up so as to make the
container more sanitary.. This construction in
addition assists in preventing pulling out of the
bottom. By the particular method used in con
structing the hoop a relatively small amount of
1/5
stretching of the metal is necessary so that an
extremely strong and substa'ntial construction ‘is
provided.
At the same time tinned iron or any
other coated metal may be used without danger 20
if injuring the coating thereof. By means of the
interlocking shoulders formed on the parts of the
bottom and wall structure of the container, these ~
parts are further held from movement relative
to one another. My improved hoop construction 25
‘serves as a hand grip by means of which the
container may be readily manipulated in the
handling of the same. Our invention is extreme
ly neat and attractive in appearance and is rigid
and substantial in construction.
Changes in the speci?c form of my invention,
30
as herein disclosed, may be made within the scope
of what is claimed without departing‘from the
spirit of my invention.
Having described my invention, what I claim 35
as new and desire to protect by Letters Pat
