METAL CAN.

SPECIFICATION forming part of Letters Patent No. 402,882, dated May 7, 1889.

Application filed March 22, 1889.

' TovaZZ whom t may concern:

Be it known that I, MAX AMS, of New -York city, New York, have invented an Improvement in Metal Cans, of which the following is a specification.

rlhis invention relates to an improvement in metal cans and boxes, and more particularly to the mechanism for opening the same.

The invention consists in the various features of improvement more fully pointed out in the claims.

In the accompanying drawings, Figure l is a side view of the upper part of aV can provided with my improvement. Fig. 2 is a vertical central section through the same; Fig. 3, aside view showing it partly opened; Fig. 4, a section on line cc a, Fig. l; and Fig. 5, a side View of a modification.

Vith particular reference to Figs. l to 4, the lettera represents the body of a metal can or box, of suitable shape in cross-section, and having overlapping upright ends soldered one upon the other. The upper end of the box is preferably enlarged, as shown, it being provided with an olfset, a.

b is the cover provided with a ilange, b', which is received within the upper part of 'the can above the offset a, as shown in Fig. 2.

In order to provide for the ready opening of the can, I interpose a separate strip of metal, c, between the two soldered edges of can a.

- This strip c projects partly outward and partly inward beyond the overlapping ends of t-he can. In manufacturing the can the strip c is placed between such ends before the latter are soldered upon each other, and thus the same operation which joins th e can-ed ges joins the strip c to the can-body.

In order to accommodate the inner or concealed end of the strip c, the body a may be bulged slightly outward above such strip, as at a2 in Fig. 4. After the can-body has been formed with the strip c in place the cover b is slipped into the upper end of the can-body and its flange b soldered thereto. The inner face of that part of strip c that projects into the can-body will also be soldered to flange b by the same operation which connects the cover to the can. It will thus be seen that the proper attachment of strip c involves but a very small amount of eXtra labor. f

Beneath the strip c the body a may be weak- Serial No. 304,334. (No model.)

ened by acircumferential indented line, d,

having a cut-away end, d.

`In use the outwardly-proj ecting part of strip c is grasped by a key or by the hand, and by it the upper part of the can-bodyis torn off, as in Fig. 3. It will be seen that after the overlapping ends of the can-body have been torn asunder above line d the inner end of strip c is still attached to flange b and must be torn from the latter. This prevents the strip from becoming entirely disconnected from the can by reason of the great strain placed upon it during the beginning of the operation. Such strain will not have a tendency to disconnect the strip from body a, but from flange h. After the can has been opened so far that the strip has been torn off the iiange b', Fig. 3, there is no more danger of the strip coming off the body a.

In Fig. 5 the flange b2 of the cover overlaps the upper edge of body a, in lieu of being inclosed by the can-body. In this modiication two indented lines, d2 d3, are formed,

and between them the strip c is secured in such a way as to partly projectbeyond the overlapping ends of body a, as previously described. .The concealed part of strip cis in this modification not soldered to the flange b2,

of the cover, but to the inner face of body a. Of course in this modication the strain on the strip c while opening the can will have a tendency to detach the strip from body a. In this respect the construction shown in Figs. l to 4 is to be preferred. i

An important feature of this invention is that the strips c may be stamped out of small pieces of waste. Heretofore when the cans were opened by a projecting tongue made in one piece with the can-blank a large amount of metal had to be wasted for the purpose of cutting out the tongue.

Vhat I claim is- 1. The combination of a can-body having overlapping upright ends, with a strip placed- -between such ends and projecting outwardly from the same, the ends being soldered 'to each4 other and to the strip, substantially as speci-l fied.

2. The combination of a can-body having overlapping upright ends, with astrip, c, placed between'such ends and projecting partly outwardly and partly inwardly from the same,

IOO

the ends being soldered to eaeh other and to the strip, substantially as specified.

3. The combination of a eau-body having overlapping ends, with cover b, havingilange b', that is received by the can-body, and with a strip, c, placed between the overlappin g ends, the strip c being soldered to flange b' and to the overlapping ends of the ean-body, substantially as specified.

4. The combination of can-body a, having 1o offset a and indented line d, with the cover b, having flange b', and with the strip c, seeured partly to the can-body and partly to flange b', substantially specified.
