"8Claims. (Cl. 93—55.1)
The present invention relates to mechanism
for assembling elements 01' cartons or containers
and refers in particular to a device for assembling
the body portion of a '?brous container with a
metallic rim member which is interlocked with
the upper edge of the body portion.
'
In employing ?exible ?brous containers for
many purposes such as in the packaging of ice
cream and other frozen commodities, it is desirn
.10 able to provide the ends of ‘the body portion of
the container with supporting members such as
metallic rims. In Patent No. 2,009,505, issued
July 30, 1935, is disclosed a container o1’_ this‘ type
and a mechanism for assembling a bottom rim
15 member with a body portion in such a manner as
to' afford support for the same. _In this container,
the bottom of the body portion is inserted in a
metallic rim and expanded to i'ormv an interlock,
the inner ?ange of the rim ?tting about the bot
20 tom edge and extending inwardly in a horizon
tal manner.

the provision of a means ,for mounting a metallic
rim about the topv of the body portion of a con

Fig. 8 is a view similar to Fig. 6 showing a ?nal
stage in the operation of the device; and
Fig. 9 is a cross sectional view, partly broken
away, of ‘a rim member of the type adapted to
be assembled by the mechanism shown in the -
drawings, together with a container.
As 'shown in the drawings, the metallic (rim
member which’ it is desired toassemble with the 10
container includes an annular'vertical wall ill
having a lower inwardly extending channel por
tion H which consists of an inwardly and up
wardly turned ?ange, the upwardly turned por
tion of which is spaced apart from vertical wall 15.
Ill. The top of the vertical wallll? is turned over:
to form a horizontal inwardly extending ?ange
i2 whichis of somewhat less width than the
channel member I I. That is, the upwardly turned
portion of the channelmember H is spaced from 20
the vertical wall in slightly more than the width
of the ?ange l2. This rim is employed on con
tainers having an edge portion of increased thick
ness, such a container being indicated at [3 in

An additional object of the invention is to pro
vide a device of the type described having an out
wardly expansible and inwardly extending guide
‘portion combined with an outwardly expansible
35 inner guide member.
(Still another object of the invention is the pro
vision of a device for, mounting a metallic rim to
an enlarged edge portion of a ?exible container,
the device including an outer and upper funnel~
“40 shaped member for overriding the upper edge of
walls.

The rim and container are assembled in the
form shown in Fig. .8. The vertical wall In of 35
the rim has an inside diameter substantially the
same‘ as the outside diameter of the container l3

distance which is substantially equal to the width
of the strip M. The height of the vertical wall 40

One end of lever 22 is pivotally attached to the
frame structure as shown at 23 and the other
end of the member 22 has a foot pedal 24. It _
will be seen that by depression of the foot lever

of the positioning member is substantially equal

be moved outwardly in a horizontal. direction
into the position shown in Figs. 4 and 5. Each 20
of the expansion members 46 is provided with
a depressed portion 41 which provides a shelf’ 48.
Extending from the shelf 48 is an elongated slot
43 which passes through the expansion member.
' Positioned on the shelf- 48 is an elongated washer 25

particularly; the cut-away portion adjacent the
40 base of the body portion receiving member is of
such size as to receive the metallic rim l0 and
to position it for assembly with the ?bre con
tainer. In this position the projection 26 just
overhangs the ?ange l 2 of the rim member. The
45 body portion receiving member consists of two
split sections 25 having backwardly extending
hinge portions pivoted to a vertical pin as shown
at 28 and supported by a bracket 29 secured
to the platform. Each of the sections 25 is
drilled adjacent the hinge 28 to provide contigu
ous openings 36 into which is inserted an ex—
pansion spring 3|. The expansion spring 3|
tends to spread the sections 25 apart and stops
32 are mounted on the platform to limit their

outer movement.
'
To the jaw of one of the sections 25 is mounted
a catch 32 which is pivoted at 33. A spring 34
presses a rear extension of the catch upwardly,
thereby biasing the hook portion 35 in down
ward position. The jaw of the‘ other section 25

is mounted in the slots 53 and causes the expan
sion units to return to their normal adjacent and
unexpanded position when ‘the plunger I3 is
moved downwardly.
The outer surfaces 55 of the expansion units 45 45
