TEABING-STRIP CAN.

Application filed October 11, 1924. Serial No. 742,999.

This invention relates to tearing strip cans and has for its object the provision of a hermetically sealed can which, when opened by removal of the tearing strip, provides a cover adapted to seat easily and tightly within the can body.

Another important object of the invention is the provision of a tearing strip can wherein the raw edge left on the can body by removal of the tearing strip is, or may be so arranged with respect to adjacent material as to greatly reduce the possibility of a user cutting his handfrom contact therewith.

A further object ofthe invention is the provision of a tearing strip can. of the above character, constructed to provide a stiff open upper end upon removal of the tearing strip.

My invention contemplates the provision of a one-piece body having an internally extending curl or bend for the reception of a friction plug cover, provided also by the removal of the tearing strip, the friction wall of which and the internal dimension of the curl can be readily given accurately like dimension to produce a liquid-tight seal when the cover is used subsequently as a closure. Numerous other objects and advantages of the invention will be apparentas it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof. One of such advantages is that the friction seat on the body is relatively thick in a direction which is horizontal or radial of the can body; another advantage is that such a seat has some yielding and spring action radially, to ad mit the friction element of the cover and tightly conform therewith to make a good closure; another advantage is that such a seat can make substantially a line contact with the friction element of the cover to make a tight closure.

On the drawings,

Figure 1 is a perspective view of a can embodying my invention;

Fi 2 is an enlarged partial section showing t e parts before the cover is seamed in place;

Fig. 3 is a similar view after the cover has been seamed in place;

Fig. 4 is a similar view after the tearing strip is removed; and

Fig. 5 shows the use of the cover as a reclosure.

For the purpose of illustrating my invention. I have shown on the drawing a sheet metal can body 11 of the usualcircular form, although it will be manifest that other shapes may be employed. Bottom and top closures, respectively indicated at 12 and 13 are provided, the bottom closure being of the usual double seamed character. The body is provided with a pair of encircling score lines 1% setting off a tearing strip portion 15, which terminates in the usual tearing tongue 16 at the side seam 17 of the can. Just below the lower score line 14, the material of the can body is bent inwardly at 18, and may be bent thence downwardly at 19, the material of the body wall above and beneath the loops being in the same plane, as may be readily seen from the drawing. The bend thus provided is open so that a rounded internal surface is provided for the reception of the friction plug cover, as will be presently described. The top 21 of the bent portion may extend over into contact, or substantially into contact with the wall of the can above the lower score line and then serves to guard the sharp edge resulting on the can body from the removal of the tearing strip.

The cover 13 is seamed with the usual double seam at 22 and from the usual shoulder or countersink 23 extends inwardly to a shoulder 24 at the top of a depression and downwardly extending friction Wall 25, thus spacing this wall inwardly of the plane of the body wall of the can and ofi'setting it therefrom. The cover thus has an offset or inset from 23 to'2 t inward from the seam 22 and can body wall. The material of y the cover is arranged horizontally below the wall 25 at 26 and therebeyond extends up again-at 27 to the body part 28 of the cover.

The can is opened by engaging the usual key with the tongue 16 and winding up the tearing strip as severance occurs along lines 14. The can thus opened provides body and friction plug parts, as indicated in Fig 4. the form of the curl and the form of the cover permitting accurate relative dimensioning between the friction wall 25 and the 105 inner face of the inward bend 18. It will be noted that the upper score line 14 is substantially at the lower edge of the seam 22, which seam provides a smooth edge, though it is contemplated that this line may be at any suitable place.

It will be manifest that the body, although constructed of a single piece, provides a stiff opened upper end, after removal of the tearing strip, for engagement with the friction plug, and also provides a smooth surface for such engagement and protects the consumer against damage from the raw tin edge at the lower score line.

It is thought that the invention and many of its attendant advantages will be under stood from the foregoing description, and it avill be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. A can, comprising a body having score rial of the body being bent inwardly within the body adjacent said tearing strip, and away from the line of that part of the can wall which is attached to the cover, and a cover seamed to the upper end of the body and having a downwardly extending friction wall arranged inwardly at a distance from the seam between the cover and body a distance equal to the inward extension of the bend of the body, said friction wall being adapted to enter within the bend after the tearing strip is removed to form a tight and readily removable closure.

2. A can, comprising a body having score lines setting off a cireumferentially arranged tearing strip near the top, the material of the body being bent inwardly within the body adjacent and spaced away from said tearing strip, and a cover seamed to the upper end of the body and having a downwardly extending friction wall offset inwardly from the external wall of the cover above the bend of the body in amount equal to the horizontally inward extension of the bent portion of said body.

3. A can, comprising a body provided with encircling score lines setting off a tearing strip, said body being bent, internally near the top to provide an external friction scat wall of accurate dimension at the top of the body when the tearing strip is removed, and a cover seamed to said body and having an inwardly spaced vertically arranged inner friction wall of horizontal diameter equal to the internal diameter of said external friction seat wall.

-1-. A can, comprising a body having encircling score lines setting off a tearing strip and provided with an inwardly extending bent part behind said tearing strip, the inner face of said bent part being curved to form an external friction seat Wall, and a cover having a downwardly extending friction wail, straight in vertical section and spaced inwardly away from the body wall, for engaging the curved wall of the bent portion after the tearing strip is removed.

5. A can comprising a body and a cover double seamed to said body, the cover having the usual countersunk portion adjacent the double seam, and having in said countersunk portion another depression of less diameter than said countersunk portion forming a wall to produce aninternal friction closure element and the can body having score lines around the same setting off a tearing strip adjacent the double seam, and the body wall being bent inward adjacent the lower score line to form an external friction closure element adapted to receive the said friction closure element of the cover.
