8 Claims. (C1. 220-27)
This invention relates to cans of that type
Fig. 8 is a sectional view similar to Fig. 3 but
which are formed with a line of weakness in one
showing a modified form of the invention;
wall thereof deñning a tear strip or tear-out por

with a cover member permanently attached to
the tear-out portion and through which force
may be applied to the latter to tear it loose from
the can, said cover member being permanently
l O attached to the can so as to form a hinge cover
or closure for the pouring opening after it has
been formed.
One of the objects of the present invention is
F to provide a can of this type with novel means for
venting the can when the contents are being dis
charged through the pouring opening. This is ac
complished by forming in one Wall of the can a
second line of weakness in addition to the line of
weakness which defines the tear-out portion
for the pouring opening, said second line of
weakness delining a second tear-out portion which
when torn from the can produces a vent opening.
I also propose to provide a cover member to
Which both tear-out portions are permanently
connected and which itself is connected to the can
body through a hinge connection.
With this construction the application of a
prying force to the cover member results in tear
ing both tear-out portions from the can body thus
forming both a pouring opening and a vent open
ing. The cover member is constructed to func
tion as a closure for both openings and as it is
hingedly connected to the can, said cover member,
after the can has been once opened, provides a
35 hinged cover for closing or opening both the
pouring opening and the vent opening.

Referring iirst to Fig. 14 l indicates a can which
has formed in the end 2 thereof two separate lines
of Weakness 3 and 4, each of which defines a tear
out portion. The line of weakness 3 is shown as
an annular line of weakness which defines the
tear-out portion 5 and the line of weakness 4 is
shown as a U-shaped line of weakness defining
a tear-out strip or portion 6.
These lines of weakness may be formed in any
suitable way so that the material of the can end
will be weaker or thinner along the lines of weak
ness than at other portions, and one convenient
way of forming the lines of Weakness is by scoring

the can end.
When the can is to be opened the tear-out por
tion 5 is torn out of the can by tearing the lat
ter along the line of weakness 3, and the tear-out
portion 6 is also torn loose from the can by tearing the can end along the line of weakness 4.
This produces a pouring opening 'I through which
the contents of the can may be discharged and
a vent opening 8 which vents the can and allows
air to enter it as the contents are being discharged
as shown in Fig. 16.
Means are provided for tearing the tear por
tions out from the can, which means also func
tion as a cover member for subsequently closing r
the openings. This cover member is indicated
at 9 (Figs. 15 and 16) and is in the form of a
strip of metal having a length to overlie both
tear-out portions 5 and 6. Said cover member is
permanently secured to both tear-out portions

moved by applying a prying or pulling force to
the end II of the cover. The U-shaped line of
Weakness 4 is situated so that the bent or bight
portion thereof is directed toward the tear-out

to the offset portion and spot welded to the tear
out portions 2|, 22 as shown at 28. The tab 2ï
of the cover member overlies the seaming flange
I6 on the can end.

ment ofthe invention wherein the cover member
is constructed so that it not only serves to tear
the tear portions loose from the can, »but after
offset lportion lI8 again thereby closing both the
pouring opening and the vent opening, and since
the can has been once opened also serves to close
both openings with a friction fit. The can shown
in Figs. 1 to '7-is of the type in which the can end
I4 is secured to the can body I 3’through the
medium of a double-lock seam I5 formed by roll
out the cover member 25 may be closed onto the
the cover member fits the oiîset portion with a
tight friction fit the can will be sealed tightly.
In the can shown in Figs. l to 'i the cover
member 25 not only provides the means through
which both tear-out portions -2I and 22 are torn
from the can toV form the pouring opening and
ing together seaming flanges I6 and I'I with
the`vent opening, but said cover member also '
which the can end I4 and ‘can body I3 are ini
functions as a tight fitting cover for closing and
sealing both openings after the can has been
opened for the first time.
The cover member is also hingedly connected
tially provided.
In this embodiment of theinvention the can
end I4 is shown as initially deformed to present
40 an elongated offset portion which maybe either
to the can so that it can never be separated there
a raised portion or a depressed portion, and said
from.
In Figs. 9 to 13 I have shown a different em
offset portion is provided with two lines of weak
ness, one of which deñnes a tear-out portion for
forming the pouring opening and the otherof
which deñnesa tear-out portion for forming a
vent opening.
I
In the construction illustrated in Figs. l to 7,
the offset portion of the can end is a raised por
tion I8 and this raised portion is provided with
the two lines of Weakness I 9 and 20, each of which
is an annular line of weakness. The line of weak
ness I9 defines a tear-out portion 2| which when
removed forms a pouring opening 23, and the
Y line of weakness 20 defines a tear-out'portion 22
which when removed forms a vent opening 24.
`A cover member is provided which frictionally
ñts the offset portion and where the offset por
tion is a raised portion as indicated at I8 I. pro
pose to employ a skirted cover member, such as
shown at 25 in Fig. 6, which frictionally ñts the
side Walls 25 of the'offset portion I8.
If the offset portion were a depressed portion
then the cover member would ñt into the depres
bodiment of the invention wherein the can end
is formed with two offset portions each of which
is provided with the line or"Y weakness defining a
tear-out portion, and the cover member is formed
with two cover portions, one for each oiîset poi'
tion, each cover vportion frictionally fitting the
corresponding offset portion. In the construc
tion in said Figs. Sto 13, 39 indicates the can body
and 3l the can end, said can end being shown as
connected to the'can body in the usual Way by
the double-lock seam 32 formed by rolling to
gether the seaming flanges .33 and 34 on the can
end 'and can body respectively.

`
'
The can end 3l. is deformed Vto `present Ytwo
oifset portions 35, 36 and these'oiîset portionsare
illustrated as in the form of -raised portions al
though they might be in the form of depressed
portions without departing from the invention. iii)
Each offset portion is formed with a line of weak
ness, the line of Weakness on the offset portion
35 being indicated at 3'I and that on »the offset
sion with a friction fit. This cover member is
65 provided with Ya tab 21 which is rolled into the
portion 36 being‘indicated at 38. `Each line of
double-lock seam I5 at the time that the can end
I4 is seamed to the can body I3. The cover
>ness and said lines of Weakness denne tear-out
> member 25 is also permanently secured to the
tear-out portions 2|, 22 and this can be readily
70 accomplished by spotwelding the cover „member
to th`e tear-out portions as indicated at 2B.
In making a can embodying this invention the
Ícan end I4 is first formed as shown in Fig. 1 with
l75
Weakness is shown as an annular line of yweak- " “‘
portions 39 and~4û. In this embodiment of the
invention the cover member, indicated generally
at 4I, is shapedto present two cover portionsV 42
Yand '43, the cover portion 42 being of a size to "
frictionally ñt the offset portion Y35 and the cover
portion 4'3 being of Va size to frictionally fit the
oifset portion 36.
This cover member 5I is also
the seaming ñange I6 and the offset portion I8 Vshownas having a tab‘44 which is adapted to be
.and also with kthe scorelines or lines vof Weakness rolledinto’the double~lock seam-32 inthe-man
'2,105,445
11er above-described with reference to the tab
27 in Figs. 1 to 7.
In making the can the can end is first formed
as shown in Fig. 9 with the seaming iiange 33 and
with the offset portions 35 and 36 and the score
lines or lines of weakness 37, 38, and the cover
member 4| is then applied to the oiïset portions
and spot welded or otherwise permanently se
cured to the tear-out portions 3S, 46 as shown
at 53. The cover member is permanently secured
to the can body in some suitable way and if the
cover member has the tab 44, then when the can
end 3l is seamed to the can body 35 the tab 44
may be rolled into the double-lock seam 32.
The cover member 4l is preferably made sulfi
ciently stiff and rigid so that when a pryingor
pulling force is applied to the end 45 thereof the
cover portions 42, 43 will be removed from the
offset portions 35, 36 of the can end and the tear
out portions 39, ¿i6 will be torn free from the can
end thus producing the pouring opening 45 and
the vent opening 41. The cover member may
be provided with the required rigidity or stiffness
in any suitable way and one simple way is to
employ a reenforcing plate 48 which overlies the
cover member and is provided with openings 49
3
the depression, and said cover member is spot
welded or otherwise permanently secured to the
tear-out portions 59, 66 as by means of spot
welding 63.
In this embodiment the cover member is shown
as permanently but hingedly connected to the
can at one end through the medium of the tab
64. The can may be opened by applying a prying
or pulling force to the end 65 of the cover which
will remove it from the depression and, because l0
the tear-out portions 59, 66 are permanently at
tached to the cover, this operation will tear these
portions out from the can end along the lines of
weakness thereby forming the pouring opening
and vent opening. After pouring out from the
can any desired part of the contents the can may
be closed and sealed again by replacing the plug
cover 6| within the depression 55 and as the plug
fits the depression with a friction fit the can
will be tightly sealed.

While I have illustrated herein some embodi
ments of the invention I do not wish to be lim
ited to the constructional details shown.
I claim:
1. A can having two separate lines of weakness
formed in one wall thereof, one of which deñnes
through which the cover portions 42, 43 project, . a tear-out portion which when removed forms
said reenforcing plate being secured to the cover a pouring opening and the other of which de
member in any appropriate way as by means of
beads 56 formed in the side walls of the cover
portions immediately above the reenforcing mem
ber. In this embodiment also the pouring open
ing and the vent opening are formed by applying
a prying or pulling force to one end of the cover
member thereby to tear out the tear portions
35, 46 and after the can has been initially opened
the cover member will provide two separate cover
members, one for each pouring opening, each
cover member closing its opening with a tight
40 friction fit.
If desired, I may employ a cover member sim
ilar to that shown in Fig. 6 in connection with
the can end having the construction shown in
Fig. 9. This is illustrated in Fig. 8 wherein there
is shown a can 30 having a can end 3i seamed
thereto with the double-lock seam 32, said can
end having the offset portions 35, 36, each of
which is provided with a line of weakness as
shown in Fig. 9. The cover member shown in
Fig. 8 is indicated at 50 and it is similar to the
iines a second tear-out portion which when re
moved forms a vent, and a cover member per
plication of a prying force to the cover member
will separate said tear-cut portions from the can
along the lines of weakness and thus form both a 35
pouring opening and a separate vent opening.
2. A can having in its end wall two separate
lines of Weakness, one of which is annular and
the other of which is U-shaped and each of which
defines a tear-out portion, and a cover member 40
permanently secured to each tear-out portion and
through which force may be applied to the tear
out portions to tear them free from the can along
the lines of weakness, the U-shaped tear-out por
tion forming a hinge connection between the cov
er. member and the can.
3. A can having a portion of one end wall olf
set with relation to the plane of the wall and
formed with two separate lines of weakness, each
of which deiines a tear-out portion, a cover mem
cover member 25 and is of a shape to ñt over the
ber frictionally engaging the oifset portion of
raised portions 35, 36, said cover member having
a tab 52 which is rolled into the double-lock seam.
In this embodiment also the cover member will

can.
as shown at 5I so that when the can is initially
opened the prying of the cover member 50 from
the can end will tear the tear-out portions 39, 46
from the raised portions 35, 36 before forming the
pouring and vent opening. The cover 5!! is con
structed so that its ends Will frictionally engage
the raised portions 35, 36.
In Figs. 1'7 and 18 I have shown an embodiment
of the invention wherein the offset portion in
» the can end is a depressed portion instead of a
raised portion, and the cover member is in the
form of a friction plug fitting the depressed por
tion rather than a skirted member ñtting over
a raised portion. In said Figs. 17 and 18 55 indi
cates the can end, a portion of which is offset to
present the depressed portion 56. The bottom
of the depressed portion is formed with the two
lines of weakness 57, 58 which define the tear
out portions 59, 66. The cover member 6| is in
the form of a plug which frictionally iits within
30
