specification.

My invention relates to improvements in the construction of seamless or drawn cans.

Heretofore 1n the practlcal manufacture and use of seamless or drawnoans ofrectangular or other shapes, such as are commonly used for preserving sardines and other arti-' cles, and in which the body and bottom head of the can are in one piece or integral with each other, the lower rounded corner of the can which unites the slightly tapering body with the integral bottom head is materially thinned and weakened by the drawing operation, and rendered liable to dentin", fracture or other injury; and great difficulty has heretofore been experienced in keeping the labels from slipping off the body owin to the taper shape 0 the drawn body and tie lack of any shoulder at the bottom end of the body to keep the label in place, a difliculty which is accentuated by the unavoidable greasy surface of the body from the sardines or other fish put up in the cans; and the drawing operation also disturbs or roughens the tin coat surface of the can body and destro s its bright tin luster so that the body of t e can not only cannot be practically covered by the label as before stated, but cannot be successfully or practically decorated, and the can as a whole presents a somewhat cheap and unsightly appearance which militates against its use, especially for the finer qualities of goods, owing to the taper shape and unbalanced form of the can as a whole, and to the lack of any efficient decoration or labeling of its body.

The object of my invent1on is to provide an improved construction of drawn or seamless can which will obviate or overcome the difficulties heretofore experienced.

My invention consists in a drawn can having its slightl ta ering body provided with a peripheral ea near its lower end, which serves not only to materially stiffen and strengthen the thinned and weakenedlower corner of the can, but also forms an external fully labeled, and which also serves to substantially overcome the unbalanced or ta ring appearanceof the can as a whole an to make it appear as a can with a straight body, and which marginal bead-also forms a nesting shoulder so that the cans-can be readily nested one on to of anotherathe portion of the can body be ow the peripheral bead of one can fittin within the countersunk cover of the can be ow it when-the cans are nested together. I v

n theaccompanying drawing formin a part of this specification, Figure 1 is a p an view of a drawn can embodying my invention. Fig. 2 is a side elevation. Fig. 3is a section on line 33 of Fig. 1, and showing also a plurality of cans nested to ether.

In the drawing, A represents t e seamless or drawn body and bottom of the can, the same being made in one piece by suitable drawing dies. The body portion a is of the necessary slightly tapering form required for facilitating the drawing operation and the practical manufacture of the cans in thisway. The bottom portion a of the can is provided with a marginal bead a which may be and preferably is formed by the drawing dies in the drawing operation. The slightly tapering body portlon a is furnished at its lower or bottom head end a with a peripheral bead (1 which is formed in the body of the vessel by a separate beading operation after the can is drawn. The seam ess or drawn body and bottom A also has a tapering or flaring corner portion a connecting the body bead a and bottom bead a The seamless or drawn body and bottom A has at its upper end a seaming flange a which is folded. into a double seam a with the seaming flange b ofthe countersunk cover B. The countersunk wall b of the cover B fits within the up or end or mouth of the body portion a an the cover B is also preferably furnished with'an inwardly projecting bead b The used'for sardines. My improved drawn can -may, however, be made of other shapes and used for preserving any articlesdesired.

0 represents the label applied to the body of the can, and'fitting between the upper external shoulder formed b the seam a and the lower external shoulder on the bod formed by the peripheral bead a, and whic l shoulders serve to hold the label in place and prevent it from slipping oil the can. The externally projecting peripheral bead or shoulder a at the lower end of the rectangular body of the can also serves to protect the label surface of the cans from marring or injury by preventing other cans from rubbing against and disfiguring the label when piled or boxed'together for shipment.

claim 1. A drawn can'having an inte ral bottom head and body and an external )eripheral seam shoulder at the upper end of its body, and an externally and laterally rojecting peripheral bead at the lower end of its bod above said bottom head, in combination wit a label held in place by said shoulders, substantially as specified.

2. A seamless drawn can havin gral bottom head and body and its ody provided at its bottom head end with an externally and laterally projecting peripheral bead above said bottom head, substantially as an inte- 3. A seamless drawn can having an integral bottom head and body and its body progral bottom head and bod and its vided at its bottom head end with an externally and laterally projecting peripheral bead, and its integral bottom portion provided with an externally and downwardly projecting marginal bead, substantially as specified.

4. A seamless drawn can having) an inteody provided at its bottom hea end with an externally and laterally rojecting peripheral bead, and its integral bottom portion provided with an externally and downwardly projecting marginal head, said can having a tapering portion uniting said beads on the ody portion and bottom portion, substantially as specified.

5. A seamless drawn can havin gral bottom head and body and its vided at-its bottom head end with an externally and laterallyprojecting peripheral bead, and its integral bottom portion providedwith anexternallyanddownwardlyprojecting marginal head, said can having a tapering portion uniting said beads on the body portion and bottom portion, said can having a countersunk cover with'which the beade body and bottom portion of the can is adapted to nest when a plurality of cans are placed one on top of each other, substantially as specified.
