METALLIC CONTAINER.

-Application filed. April 12,

This invention relates to a metallic container and particularly to a metallic container of an improved type which may be readily made by the general method described in my United States Letters Patent No. 1,556,651, of October 13th, 1925.

It is an important object. of this invention to provide a metallic container, such as an ice cream can, wherein the bottom is joined to the body portion in such a manner as to afford a strong, durable and inexpensive construction which is smooth and regular in contour both inside and outside.

Other and further important objects of this invention will be apparent from the disclo-. sures in the specification and accompanying drawings.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described. \I

Onthe drawings:

Figure 1 is a fragmentary sectional view illustrating the first step in the construction of a metallic container embodying the principles of'this invention.

Figure 2 is a similar View showing the second step in construction.

Figure 3 is an enlarged fragmentary detail vertical section showing the completed joint between the bottom and body portions of the container. I

As shown on the drawings:

The reference numeral 1 indicates the cylindrical body portion'of a metallic ice cream can or similar container. As will be noted, the lower edge of said body portion 1 is scarfed or bevelled as at 2 and abottom portion 3, which is initially upwardly dished as ically engaged inside the lower end of sai body portion. Said bottom portion 3 is provided with a de-' pending flange 4 which is reversely bent at 5 to form a rounded'bottom support. Said reversely bent (portion extends upwardly as at 5 contiguous to the flange 4 and isscarfed at its upper edge to form asmooth joint with the scarf. dodge 2 of the body portion 1. The bottom and body portions are secured together preferably by electric welding as in-, dicated by the heavy line 6, this welded portion extending entirely around the container and, of course, being of any desired width to properly secure said portions together. 7 After the bottom and body portions have thus been secured in' themanner previously durable,

1926. Serial No. 101,337.

referred to, the upwardly dished bottom portion 3' is forced into the downwardly dished position indicated in Figures 2 and 3 by a method such as shown in by aforesaid Patent No. 1,556,651.

The container is preferably dipped in a coating of metal such as molten tin or the like,

prior to effecting the latter operation so that the effect of an entirely seamless structure.

By providing the rounded portion 5 at the beginning of the reversely bent portion 5 a smooth durable bottom support for a con tainer is afiorded, and by providing a smooth jointat the scarfed edges of the body portion 1 and the upwardly extending part5 of the reversely bent portion,,it is possible to provide an ice cream can having an entirely smooth exterior which facilitates the withdrawal thereof from an ice chest in which it may be packed entirely surrounded by ice.-

The construction which neat in appearance, and may be economically manufactured.

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted, otherwise the body and shorter than the full length of the bottom, bringing the bottom and bbdy members together and then welding the upper extremity of said exterior layer to the lower extremity of said body.

2'. The method of making a container WlllCh consists in forming in an open-ended sheet I have provided is metal body a sheet metal bottom having a shorter than the teleseoped portion, and then joining the upper extremity of the exterior layer to the lower extremity of the body.

3. The method of making a container which consists in forming a sheet-metal bottom member of two portions, one being of less diameter and longer than the other, making an open-ended sheet metal bod telescopically inserting the longer of sand portions within the open-ended sheet metal body until the upper extremity of the other portion abuts the lower extremity of said body, and then joining both portions to said body.

4;. A container including a sheet metal body, and a sheet metal bottom formed to define-two portions, one of which is of less diameter and of greater length than the other, said portion of the bottom of least diameter being inserted within the body andthe portion of greatest diameter abutting the lower extremity of the .body at theupper extremity of said portion of greatest diameter,said portion of greatest diameter being joined to said body.

5. A container including a sheet metal body, and a'sheet metal bottom formed to define two portions, one" of which is of less diameter and of reater length than the other, said portion of the bottom of least diameter being inserted within the body and the portion of greatest diameter abutting the lower extremity of the body at the upper extremity ofsaid portion of greatest diameter, said portion of greatest diameter being welded to said body.

6. A container including a sheet metal body, and a sheet metal bottom having a depending annular portion partially telescoped within the body-and folded on itself with the exterior layer of the same diameter as the external diameter of the body, the upper extremity of said external layer abutting the lower extremity of the body and being joined thereto.

7. A container including a sheet metal body, and a sheet metal bottom formed to define two portions, one of which is of less diameter'and of greater length than the other, said portion of the bottom of least diameter being inserted within the body and the portion of greatest diameter abutting the lower extremity of the body at the upper extremity of the portion of greatest'diameter, said portions being joined to said body.

In testimony whereof I have hereunto subscribed by name.

JAMES P. WALKER.
