CONTAINER Filed Jan. 26, 1951 @T7-GEMA??? Patented Nov. 7, 1933 UNITED STATES PATENT OFFICE Application January 26, 1931. Serial No. v511,208 'y 1 claim. V(C1. 22u-54")- This invention Yrelates to containers ofk the type wherein a ortion of the container is torn to unseal and open the container. For example', a sheet metal may be permanently sealed at the top and bottom, and provided With Weak circumferential lines to produce a removable `portion adapted to beitorn from the can body.

One of the. objects is to produce a Ysimple and inexpensive container of this type, having its elements so combined with each other that the container can be easily manufactured, readily scale-:band conveniently opened. The closure is adapted to serve as a lid, or closure, for the een body when the container is sealed and aiso when the removable portion is torn from the container. Y

More specifically stated, an object is to pr0 duce a simple can body having .a closure seat below the removable portion which is torn irom` the body, thereby eliminating the relatively expensive additional elements usually employedtothe removable tearing strip, I eliminate the separate, or additional, elements referred to above.

The spe-cie structure hereafter described includes other advantages which will be apparent to those skilled in this art. Y

With the foregoz'urr and other objects in View, the invention comprises the novel construction., combin ienand arrangement of parts hereinafter more speciiically described and illustrated in the accompanying drawing, wherein is shown the preferred embodiment of the invention. However, it is to be understood that the invention eomprehends changes, variations and modiiicatioils which come Within the scope of the claim hereunto appended.

' Fig. 1 is a side elevation of a sheet metal can embodying the features of this invention.

Fig. 2 is an enlarged horizontal section on Vthe line 2--2 in Fig. 1, showing the vertical seam which extends from the bottom of the Y can to the tearing strip.

.o Fig. 1il isan enlarged vertical section showingv a portion of the can vbody Qand'closure as they appear beforethe closure is connected to the can body. f. Y A

Fig. 5 is an enlarged vertical section Ion the line 5--5 inV Fig. 5, showing `hovv they closure may be permanently unitedqwith the uppe margin of .theCan body. f

Fig.` 6isa View similar to Fig. 5, with the tearingstrip removed and the closure seated onv a portion of `the canV body entirely below the formeilocation of the tearing strip. I-Will now describe the `accompanying drawingvvhich illustratesrone form 'of the invention.

The can body A may be connected to the bottom by means of a seam 6,1in the usual or any seam includes a ilange on the closure interlocked With'a ilange 9 at the upper margin of the can body.

After the can has been filled, the air may be exhausted'to create a vacuum, or partial vac- 180 uum, in the can body. The closure may be applied as shown in Fig. Land the

flanges

8 and 9 may then be'forced to the positions shown byA Fig. 5,so as to forma seal at the junction of the closure and can body. However, the inven. tion is not limited'to these details. Y

` The can body isl weakened in circumferential lines 10 to provide a removable portion 11 adapted to betorn from the Vcan body. As shown by Figures 1 and 3, agfree'tongue 12 extends from this removable portion, said tongue being adapted to receive a key or other device whereby the strip 11 is removed.` Y

The vertical portion of the, can body may bek a single sheet of metal having its vertical edges connected by means of an' interlocking seam 13 (Figures 1 and 2) extending from the bottom of the can to the lower weakened line 10, Where the vertical seam terminates and merges Vinto plain lapped portions 111V and 15 united by solder ,y 16 (Figures land 3). These plain lapped

portions

14 and 15 extend from the closure' B to the upper end of the vertical seamy 13. The free tongue 12 extends from the outer lapped portion 14, and this portionA has an inclined edge 16 (Fig. 1) extending from the upper weakened line 10 to the closure'. Y

A V-shaped recess is thus formed vbetween f the inclined edge 16 and the top ofthe tongue'. 12, and the point of this` V-shaped recess is inV vertical alinement with the outer vertical fold in the seam 13, as shown in Fig. 1. Y

Since the lower edge of the tongue 12 extends from said vertical fold, while the upper edge extends from the point of the J-shaped recess, the tearing operation is positively started at the weakened lines 10.

' I` will now describe the closure and elements associated therewith as shown most clearly in Figures 5 and 6.

The closure includes a top wall 17 and a two-V ply flange 18 connecting said top. wall to the seam '7.' The metal is folded Vat the lower edge of the flange 18 to provide a smooth rounded edge.

When the can is sealed,` the closure extends into the can body and engages the inner face of the upper margin 19 which is permanently united with the closure. In the preferred form of the invention, the closure also engages the inner face 'of the removable tearing strip 11, as shown in Fig. 5.

It will be importantto observe that the can body includes a closure seat 20 belowthe removable strip 11. Aninternal bead 21 is formed below the seat 20. Y

When the elements are'arranged as shown in Fig. 5, the removable tearing strip 1l separates the closure from the seat 20, but when said strip isV removed, the closure fis'detached and may be applied to the canas shown in Fig. 6, wherein it extends `into the can body and frictionally engages said seat 20. The bead 2l then serves asa stop to limit the inward motion ofl the closure. f

- The simple can body includes the upper margin 19 permanently secured to the can body, the removable tearing strip 11 immediately below said upper margin, and the auxiliary closure`-4 seat 20 below the tearing strip. These simple elements can be conveniently made of the same diameter, corresponding to the diameter of the can body, without the use of any additional'elements to receive the closure whenA the tearing strip is removed.

In other words, an ordinary simple can body of uniform diameter may be formed with the novel combination and arrangement of elements to produce a very simple key-opening can, having the advantages of more complex and expensive cans of this type.

I claim:

A container comprising a sheet metal can body having a closure united with its upper margin, `said can body being weakened in circumferential lines to provide a removable portion adapted to be torn from the can body, said can body having an internal closure seat extending downwardly from its upper edge, across the inner face of said removable portion and into an area below said removable portion, said closure being provided with an intergral two-ply flange folded at its lower edge, said integral two-ply iiange being extended downwardly from its upper edge, across the face of and in contact with said removable portion, said integral two-ply flange being separated from the lower lportion of said internal seat when the `container is Vsealed, and adapted to engage said lower portion when said removable portion is torn from the can body, said can body being provided with an internal bead locatedv below said lower portionof the internal seat and serving as a stop for the closure when said removable portion is torn from the can body.
