Application May 6, 1937, Serial No. 141,064 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 Fig. 9 is a perspective view of an end showing tion, which when torn loose from the can forms a a different embodiment of the invention from that CI pouring opening, and which are also provided shown in Fig. 1; 5 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. be pointed out in the appended claims. ` , Fig. 1 is a perspective View of a can end showing one embodiment of my invention; Fig. 2 is a section through the can end on the line 2_2, Fig. 1 showing in dotted lines a can body to which the can end is to be attached; Fig. 3 is a section on the line 3-3, Fig. 5; Fig. 4 is a section similar to Fig. 3 but showing 50 the can opened; Fig. 5 is a perspective view of a can embody ing my invention; m Ul end is to be applied; Fig. 11 is a section on the line lI-I I, Fig. 13; Fig. l2 is a sectional view similar to Fig. 11 but showing the can opened; Fig. 13 is a fragmentary perspective View of the can shown in Fig. 11; Fig, 14 is a perspective View of a can showing still a different embodiment of the invention and before the cover member is applied to the can; Fig. 15 is a perspective view of a completed can showing the construction illustrated in Fig. 14; Fig. 16 is a section on the line 16-1 6, Fig. 15 but showing the can opened; 20 Fig. 17 is a fragmentary sectional view show ing a different embodiment of the invention; Fig. 18 is a section on the line Iii-I8, Fig. 1'7. 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 vIn order to give an understanding of the inven tion I have illustrated some embodiments there of in the accompanying drawings which will now ‘10 be described after which the novel features will In the drawings: Fig. 10 is a section on the line Ill-l0, Fig. 9 showing in dotted lines the can. to which the can Fig. 6 is a perspective view of the cover member; Fig. '7 is a section on the line '1_-1, Fig. 3 ; 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 2 2,105,445 as by means of spot Welding indicated at IU, Vand the cover member is of suiììcient stiiîness or strength so that the tear-out portions can be re Cn 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 I9 and 23. The cover member 25 is then applied 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. . The assembled can end I4 and cover member 25 .are then attached to the can body I3 by roll portion 5, and with this arrangement the appli ing the seaming ñanges I6, I'I together to form cation of a prying or pulling force to the end II of the cover member 9 will result in tearing the tion the end of the tab 21 is rolled into the dou tear-out portion 5 completely loose from the 'can and in also tearing thetear strip 6 free from the can along the line of Weakness 4. Since the the double-lock seamV I5, and during this oper - ble-lock seam, thus permanently connecting the cover member to the can. When the can is' to be opened a prying or pull line of weakness 4 is U-shaped, said tear strip-6 Y ing force is applied to the end 29 of the cover will remain permanently connected to the can -suiiicient to tear the tear-out portions 2|, 22 free from the raised portion I8 of the can end thereby end and this tear strip then forms a hinge con nection I2 between the cover member 9 and the Vforming the pouring opening 23 and the vent opening 24. The tab portion 21 of the cover, With this construction the can may=be readily which is permanently connected to the can body, opened by applying the prying or pulling force constitutes a hinge for the cover member. The ' Ato the end II of the cover member, as stated provision of the vent opening provides for freely above, and after the can has'once been opened pouring liquid contents from the can without it will be'provided with a hinge cover which- 'can any gurgling action, and vif vit is desired to dis be used for closing both the pouring opening charge a portion only of the contents of the can, can. Y and the Vent opening. In Figs. 1 to 7 I have shown another embodi then after the desired amount has been poured 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. 20 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 the can end and permanently secured to both tear-out portions, and means permanently but hingedly connecting said cover member to the be spot welded to the tear-out portions 39, 46 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 manently secured to each tear-out portion and hingedly connected to the can, whereby the ap 50 4.
