CONSTRUCTION OF METALLIC CONTAINERS.

Application filed March 6, 1922. Serial No. 541,301.

To all whom it may concern:

Be it known that I, HENRY S. RnYNoLDs, a citizen of the United States, and a resident of the borough of Brooklyn, in the city of New York, county of Kings, and State of New York, have invented an Improvement in the Construction of Metallic Containers, of which the following is a specification.

Thi invention relates to construction for metallic containers and the like, particularly to fluid-tight closures for the same and to the art of securing bail members to such containers.

One of the objects thereof is to provide a construction of the above nature which is.

inexpensive and easily made. Another object is to; provide a strong and dependable construction of the above nature which is well adapted to meet therequirements of hard, practical use. Other objects are to provide a construction of the above nature formed of sheet metal and in such a manner that the metal is not severely strained and is economically used to'provide a maximum containing capacity.

Another object is to provide a method of fastening bails to such containers that may be simply and inexpensively carried out. Other ob ects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements, arrangements of parts, and in the several steps and relation and order of such steps all as hereinafter pointed out, and the scope of theapplication of which will be in dicated in the following claims.

In the accompanying drawing in which is shown one of the various possible embodiments of this invention,

Figure 1 is a view of the top portion of a metal container showing the cover removed;

Figure 2 is a sectional view through the top portion shown in Fig. 1 with the cover secured in position;

Figure 3 is an enlarged view showing the means of inserting the bail shown in Fig. l; and

Figure 4 shows the bail secured in position.

Similar reference characters refer to similar parts throughout the several views of the drawing.

Referring now to the drawing in. detail, there is shown a container shell 10 preferably of cylindrical form. The open end or top portion only of the container is shown since it is principally within this portion that the invention resides. The shell is preferably made of one sheet of metal shaped to cylindrical form and with its vertical seams secured by a suitable means such as welding. The closure for the bottom of the shell may consist of a metal sheet properly welded into place.

Shell 10 has areferably stamped or rolled on the outside thereof a depression or groove 11 extending circumferentially around the shell near its open end. Groove 11 is preferably formed with a gradually curved con tour avoiding sharp bends in the metal and the resultant danger of overstraining and cracking the same. The depression or groove 11 thus forms a circumferentially extending shoulder 1a of rounded contour on the inside of the shell. Above groove 11 the portion 12 of the shell extends vertically in substantial alignment with the rest of the shell wall below the groove and terminates in a plurality of normally upstanding tongues 13 shown in this position in Fig. 1.

The cover 15 is preferably stamped from sheet metal and is of an outside diameter equal to the inside diameter of the shell. Its edges are preferably curved upwardly to a slight extent and then over and downwardly to form an upstanding flange 16 at its periphery of substantially the width of portion 12 of the shell. At the bottom of flange 16 the metal is bent inwardly and downwardly to form a curved flange 17 adapted to mate with the curved shoulder 14 on the inside of the shell.

In Fig. 2 the cover is shown in place in the open end of the shell. A packing ring 2 1 of felt or other suitable material is preferably clamped between flange 17 of the cover and shoulder 14k of the shell; and the upstanding flange 16 rests snugly against the portion 12 of the shell. Tongues 13 are bent into place over the top of flange 16 and the cover is thus securely fastened in position. The curved portion of shoulder 14: joining shell wall 12, and the curved flange 17 fit the'contour of packing 18 and a maximum bearing surface between the metal and the packing is provided thus insuring a positive liquid-tight closure.

It will be seen that the container as above set forth is particularly economical in the amount of metal used in its construction and provides a maximum interior volume relative to its external dimensions. The exterior walls being in alignment throughout permit packing of a number of the containers closely together without waste of space. Furthermore, the metal is not weakened by undue distortion of the same in forming the various shoulders and flanges ol' the shell and cover. Also there. are no sharply projecting shoulders onthe inside of the container to interfere with the removal of material therefrom.

A bail 18 isshown secured to the walls of the shell by an attaching device which preferably takes the form of strip of metal 19 secured to shell 10 by means of rivets 20. Strip 1 9 is preferably bent outwardly at a: portion intermediate of rivets 20, as at 21, so that this portion is spaced from the wall of the shell, This spaced portion is provided with an opening to receive bail 18 and its portion below the opening is cut as at 2:2 (see Fig. d) preferably in line with verticalj side of the opening. T hus there is provided a portion 23 which, may be bent outwardly, as shown in Fig. 3, to permit the insertion of the curved end of the bail and may then be bent back to the position shown in Fig. 4; to lock the bail end in place. Thus the end ofbail 18 may be sharply hooked or headed before attaching and after insertion is securely held in place so that it cannot slip out of its fastening.

As many changesmight be made in the above arrangement and as many variations might be made, in the art above described without departing tromfthe scope of the invention, it isintended that all features herein described or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

I claim as my invention:

1. In construction for metallic containers, in combination, acontainer shell having adjacent its open end an. inwardly extending shoulder, and a cover for said shell having formed, at its periphery a substantially upright flange, adapted to rest against the wall ot' said shell. above said shoulder, said up right flange terminating at its lower end below the body of said cover in an inwardly directed lip adapted to, rest upon said shoulder and support said cover thereon.

2, In, construction for metallic containers in, combination, a container shell having adjacent its open end an inwardly extending shoulder, and a cover for said shell having formed. at its periphery a substantially upright flange adapted to mate with the wall ofsaid shell. above said shoulder, said upright flange terminating at its lower end in an inwardly and downwardly extending lip adapted to rest upon said shoulder and sup,-

port said cover thereon.

3. In construction for metallic containers, in combination, a container shell having acen't its open end an inwardly directed shoulder or rounded contour, and a cover for said shell having formed at itsv periphery a substantially upright flange adapted to mate with the wall of said container above said shoulder, said upright flange terminating at its ower end in a portion rounded inwardly and downwardly to mate with said rounded shoulder and support said cover thereon.
