METAL CONTAINER.

Specification of Letters Patent.

Patented Nov. 29, 11921.

Application filed September 23, 1920. Serial No. 412,273.

To all whom it may concern:

Be it known that I, HUGO P. GEIsLER, a citizen of the United States, residing at 720 Riverside Drive, New York, N. Y., have invented certain new and useful Improvements in Metal Containers, of which the following is a specification.

My invention relates to containers with a metal end or ends whose contents are liable to evolve gas, thus causing the walls to swell or the ends to bulge, and which are often rejected erroneously because of a bulging of the tops not due to fermentation but to the shocks or blows given by the contents to the ends or sides, in their transportation, or in the handling of the containers.

Oneof the objects of my invention is to greatly lessen or prevent the bulging and buckling of the ends,.and also to prevent what are known in the trade as springers. or slackers produced by the dropping of the container or case in which the containers are packed for shipment.

Another object of my invention is to enlarge the carrying capacity of the container without enlarging its size where the material within the container is such that will not permit the soldering of the ends to the body of the container.

Another feature of my invention is, to construct a rim or flange on a container that will act as a base or cushion against which the ends rest and press in the event of pressure from within; also to prevent the sides of the container being torn away from the ends of the flange or rim joint of the container, in the event of the container becoming crushed.

Another object is to construct a rim or flange on a container that will be air tight and leak proof without the aid of a gasket.

One or more illustrative embodiments of my invention are represented in the accompanying drawing, viz.

Figure 1 is a side elevation of a container embodying my invention, the top and bottom being the same.

Fig. 2 1s a top or bottom view of the container of Fig. 1.

Fig. 3 illustrates one step in making the flange.

F1 s. 4 and 5 are sectional views showing two onus of flange or rim of the container and the manner in which the ends (top and bottom) are fastened to the side or body of the container and held in place.

' j ected, thus 'causlng Fig. 6 shows a top with a different kind of corrugation.

Fig. 7 is a section of the lower portion of the contalner shown in Fig. 6, on line 1-1.

Shipments of metal containers such as cans of condensed milk are frequently regreat loss, because of the appearance of swelled, bulged or buckled ends on some of the cans, erroneously attributed to spoiled contents due to fer- 'mentation and gas forming inside the container whereas in many cases the buckled or bulged ends arise from the blow givento the ends of the containers by their contents when they are dropped from a height or violently knockedin shipping. Although the containers are stacked upon each other their ends are unsupported and are free to move under the blows and shocks dealt by their metal between the corrugations will not'be' flexed, due to shocks on the ends or crushing of the sides. The entire center of the ends (top and bottom) is ridged and non-flexible when crushed or dented at the sides of the container. The spaces between the ribs are preferably not wider than the ribs. due to spoiled contents and consequent gas formation with resulting high pressure will, however, bulge the sides of the container or even the tops so that they can be readily detected and the cans rejected.

Referring to the drawings, it will be observed that in the construction of the ends from tin or other metal, I, by suitable means, form preferably in ridges straight across as shown in Fig. l, at 1, all or a portion of the metal'forming the ends (top and bottom) surrounded by the flange or rim 2 of the container. I leave a slight space 3 which may be used for cutting purposes between the ends of the corrugations 1 and the flange or rim 2 in such a manner as to give the greatest strength and rigidity to the metal used and serving to anchor the ends of the corrugations therein.

The corrugations 1 in the ends (top and swells I bottom) of the container are to be of suflicient height and of suflicient number so as to give the requisite strengthand rigidity to the metal used, according to the size of the container, and are preferably of uniform width and uniformly spaced. The corrugations are so closely spaced that the metal "between the corrugations will not be flexed, due to shocks on the ends or crushing of the sides. They are of such a height that the outside surface of the ends (top and bottom) 1*, 1 1 will, when the endsare in place on the container, be approximately on a level with the top of the edge of the rim or flange 2 or side. of the container. Or the ends (top and bottom) of the container, may be crimped in any design desired and the ends (top and bottom) slightly bulged outward, sothat the outside surface and center of the ends (top and bottom) will, when the ends are attached to the body of the container, be on a level with the top of the edge of the rim or flange 2 or side of the container (see Fig. 7).

11 either case the outside surface 1, 1 1 of the ends (or center when bulged outward) as well as the rim or flange 2 of the container will be approximately flush with, or resting approximately on the shelf or article on which the container is placed. Or, in shipin when one container is placed on top oft e other, (end to end) the outside surface 1*, 1, 1 of the ends, as well as the flange or rim 2 will be resting against each other,

thereby preventing the ends (top and bottom) from bulging, springing or buckling in the event of rough handlin or being dropped while packed in cases for s ipment.

Where the container is constructed as a receptacle for articles that will not permit the soldering of the ends to the container after filling, as when used to store condensed ceptacle for oils, gelatin like compounds milk, the outside portion 4, 4* of the metal of the ends is suitably bent so as to form a groove (Fig.3) with sides of equal depth to fit and slip over the top 5 of the side 5 (Fig. 3) of the container, Before putting the ends on to the container and fastening them in place, the groove in the end into which the top 5 of the side 5 of the .container is inserted may, or may not, be filled with a proper self cementing substance as for example, paraflin, waxy or resinous compounds of a suitably high melting point; or, when the containers are to be used asa reinsoluble in oil, may be used, the kind depending upon the article the container is to hold. After placing the ends on the container and inserting the top 5 of the side 5 into the groove (Fig. 3) the same is tightly crimped and compressed, and then may be bent outward and crimped as in Fig. 4, but preferably according to the best em- -bodiment of my invention, bent inward and down against itself, and again tightly crimped and. compressed forming the rim or flange 6 of Fig. 5 with top 6 and base 6 The rim or flange so formed more securely fastens the ends to the container, gives a long anti-leakage path, and acts as a base or cushion against which at 6 the ends (top and bottom) rest or press in the event of pressure from within. The rim or flange so formed produces'a more rigid and air tight flange, rim and joint, than present methods; and also prevents the side 5 from being torn away from the flange in the event that the container be crushed; besides reducing the effective diameter of the container at the ends by the thickness of the rim or flange,

if it were on the outside, thus enabling more containers to be packed in the same space.

The flange is free from leakage and does away with the use or necessity of a gasket that is now used and in many cases found objectionable tothe contents of the tins or containers, where an air tight and leak proof joint, flange or rim is required.

In the embodiment of the invention shown -in Figs. 6 and 7 the corrugations 8 start a short distance from the rim, to give a cutting strip which anchor the ends of the corrugations, and run spirally toward the central portion, leaving space for a number or mark. The central portion or topmost portion 9 is on a level with the rim.

Where the container is constructed to act as a receptacle for articles where the ends (top and bottom) of the container, the outside portion of the tin, or metal of the ends surrounding the crimp or corrugation is sufiiciently raised and formed so that when the ends are fastenedand soldered to the container, the outside surface of the ends will likewise be approximately on a-level with the top of the edge or side of the container, the same as containers where the ends are not soldered, as heretofore described.
