Patented Oct. 7, 1947 CONTAINER Hjalmar Kinberg, Ross, Calif., assigner to American Can Company, New York, N. lY., a corporation of New Jersey Application December 28, 1944, Serial No. 570,161

The present invention relates to sheet metal containers or cans and has particular reference to a hermetically crimped end seam for a raw uniianged edge body to provide a can which is hermetically tight and which will resist high internal pressures.

An object of the invention is the provision of a can of simple construction which may be manufactured economically and which has an end closure which may be attached to a raw unflanged edge body 'in a manner that will be hermetic and yet will resist removal or relative displacement under high pressures withinthe can.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawing:

Figure 1 is a perspective view of a can embodying the -instant invention; and

Figs. 2 and 3 are enlarged vertical sectional views taken substantially along planes indicated by the lines 2-2 and 3 3, in Fig. 1 with Fig. 2 being taken through the side seam of the can, parts being broken away.

As a preferred embodiment of the instant invention the drawing illustrates a can which includes a tubular body II having a side wall section I2 (Fig. 3) and a conventional lock and lap side seam I3. Adjacent its end edges, the body wall section IE is formed with an outwardly extended ofset curved shoulder I5 which merges into a larger diameter body Wall section I6. This larger body wall section slopes or flares outwardly at a slight angle t0 the vertical and terminates in a raw edge I'I which is without hem, flange, or curl of any kind.

The opposite ends of the body I I are closed and sealed with end closures 2|. These end closures are each formed with a countersunk central panel 22 which merges into a surrounding inner flange or upright stepped wall section 23. This 1 Claim. (Cl. 22B- 67) upright wall section extends below and above the channel 21 in which is enclosed the raw edge of the body and the shoulder. The channel carries a sealing compound 28V in which the raw edge I'I is embedded, this construction providing a hermetic seal between the closure and the body.v

The outer cover flange 26 tightly engages the outer surface of the body wall sections I12 and I6 and follows the contour of the body past and under the shoulder. The Bange terminates just below the shoulder and merges into an increased thickness reversely folded hemmed edge having a broad base 3l which perferably is flaton the bottom. The base merges into and terminates in an inner upright flange or edge 32 of the hem which is folded back against the inner surface of the outer flange. This hem extends entirely around the ange, and is interposed between the flange and the can body and tightly engages both.

The hemmed edge 32 extends up along the body wall section I2. The upper end of the hem curves slightly outward, under and against the shoulder I5 and terminates in a raw edge 34 which abuts against the shoulder. One sharp corner of the raw edge is embedded slightly in the shoulder -while the other corner is embedded in the outer flange at a locality adjacent the shoulder, as best shown in Fig. 3. At this point in the outer flange, its thickness is reduced along the curve of the shoulder to bring it into tight engagement with the shoulder. Sealing compound in the channel between the inner and outer ilanges and in the slight space adjacent the raw edge 3Q oi the cover hem provides for and insures a hermetic seal between the body and the outer flange at the shoulder.

At the side seam I3 of the container the same construction of end seam is provided as shown y in Fig. 3 with the exception that there are two thicknesses of body material instead of one. However, these two layers of material are soldered together during forming of the body and thus function as a single or unitary layer.

With such a construction of end seam any internal pressure in the can tending to displace a closure member 2l is resisted by the raw edge 34 of the hem 32 biting into the shoulder I5 of the body. The pressure is transmitted through the hem endwise or longitudinally and is absorbed by the heavy or thickened base 3| at the line of fold between the hem and the outel` flange 26.Y The slightly curved upper end of the hem tends to direct this pressure inwardly toward the side wall section I2 of the body which thus forms a back stop in resisting displacement of the closure member.

simple in construction; and economical ormanufacture.

It is thought that the invention and many of its attendant advantages will be understood from,V

the foregoing description, and it Will be apparent that various changes may be made in the form,- Y

construction and arrangementof the partswithfout departing from the spiritv andscopeofftheinvention or sacrificing all of its material advantages, the form hereinbefore described being,

merely a preferred embodimentthereof:
