CLOSURE FOR CONTAINERS
Thomas L. Varker, Wilkes-Barre, Pa., assignor to
Continental Can (Jompany of Pennsylvania
Application May 20, 1936, Serial No. 80,839
1 Claim. (Cl. 220-55)
This invention relates to metal containers and
more especially to containers having closures an apron H) which can extend below bead 2.
Packing II is seated in the channel so as to bear
adapted to be tightly held so as to seal the con
upon bead 2 when the closure is in position.
t‘ainer.
The clips 6 are so shaped and proportioned
5
Heretofore considerable structure has been re
that
after the closure has been placed in posi
quired to provide a quickly detachable closure or
cover which, while in use, could be held tightly tion, they can be pressed over the ?ange of the
10
pressed to its seat on the container.
An object of the present invention is to pro
vide holding clips for lapping and pressing
against the closure when seated, these clips being
mounted in a. new and novel manner so that it
becomes unnecessary to employ separate specially
attached fastening means for the clips.
15
Another object is to provide supports for the
clips adapted to hold the clips so that they can
be used in connection with a closure having a
broad ?ange or apron depending therefrom.
Another object is to provide a structure which
20 can be manufactured readily and at low cost.
With the foregoing and other objects in view
which will appear as the description proceeds,
the invention consists of certain novel details of
construction and combinations of parts herein
25 after more fully described and pointed out in the
claim, it being understood that changes may be
made in the construction and arrangement of
parts without departing from the spirit of the
invention as claimed.
30
In the accompanying drawing the preferred
form of the invention has been shown.
In said drawing
Figure 1 is an elevation of a portion of a metal
container having a closure fastened thereon by
35 means of the improvements constituting the
present invention.
.
Figure 2 is a section on line 2—2, Figure 1.
Figure 3 is a section on line 3-3, Figure 1,
the clip being shown by broken lines in released
40 position.
Figure 4 is a section on line 4-4, Figure 3.
Referring to the ?gures by characters of ref
erence, I designates a sheet metal container the
top edge of which is rolled outwardly to form
45 a tubular bead 2 the bottom portion of which is
cut away at desired points as shown at 3. Fitted
snugly in the bead is a stiff. bead wire 4 and at
those points where the bead is cut away the wire
is formed with depending angular yokes 5.
Mounted to swing on the bottom portion of
each yoke is a clip 6 formed preferably of strong
resilient metal, there being lugs ‘I at one end
of the clip which embrace the yoke so as to hold
the clip thereto.
55
The closure 8 is adapted to ?t down into the
upper portion of the container and is formed
with an annular ?ange 9 constituting an invert
ed channel the outer side wall of which forms
closure and will force it downwardly so as to
compress the packing within the channel and
upon the bead. Consequently the container will
be sealed.
10
The free end portion of each clip forms a seat
l2 which engages the top of the ?ange l0 when
the closure is sealed and as this point of engage
ment is substantially in vertical alinement with
the pivotal center of the clip, there will be no 15
danger of the clip swinging laterally out of en
gagement with the ?ange l0 after the closure
has been fastened. Each clip is of a strong
resilient material and thus constitutes a spring
which holds the clip constantly pressed tightly 20
on ?ange Ill.
The lugs '! on the clips can be made angular
as shown. Thus when a clip is swung outwardly
and downwardly to the position shown by broken
lines, the yoke will yield to allow the angle of the
lug to move upwardly back of the yoke so that 25
a flat face of the lug can come into position where
it will be clamped between the yoke and the
side of the container. Consequently the clip
when thus located, is held against free swinging 30
movement.
To remove the closure the free end of each
clip. ii is sprung upwardly a sui?cient distance to
allow the clip to swing outwardly from engage
ment with ?ange ID. The closure is then free to
be unseated.
By providing depending yokes integral with
the bead wire it is possible to dispense with
special attaching means for the clips requiring
riveting or welding and it is also possible to 40
mount the clips where they will not be interfered
with by the depending apron of the closure.
All of the parts are cheap to manufacture and
easy to assemble.
What is claimed is:
45
A sheet metal container and a closure therefor
comprising a body portion having an outwardly
rolled hollow head at the upper end thereof, said
head having cutaway portions, a wire disposed
within said head and extending around the con 50
tainer, said wire being bent at said cutaway por
tions to form depending yokes extending down
wardly along the outside of the body wall, and a
resilient clip pivotally secured to each yoke and
dimensioned so as to contact with said closure 55
when turned to a position overlying the same for
holding the closure on the container.
