SHEET-METAL GAN FOR SARDINES.

Specification of Letters latent.

Patented Sept. 29, 1914.

Application led October 1, 1910. Serial No. 584,788.

` Sardines,- of which the following is a specification.

My invention relates to improvements in sheet metal cans for sardines or other articles. rllhe object of my invention is to provide a sheet metal sardine-can of a simple and efficient construction, capable f beingcheaply manufactured, which may have its cover soldered on the body after the can is filled and without danger of scorching or injuring the contents of the can or the flavor thereof. f A further object is to rovide my improved can with means or conveniently opening the same.

My lnvention consists in the novel `construction of parts and devices and inthe novel combinations of parts and devices herein shown and described, and by which'I accom lish this object or result, the same being partlcularly set forth in ,the claims.

In the accompanying vdrawing forming a part of this specification, Figure 1 is a perspective view of a sheet metal can for sardines or other articles embodying my invention. Fi 2 is a plan view. Fig. 3 is a section on l1ne 3-3 of Fig. 2. Fig. 4 is 'a section across Fig. 1 and Fig. 5 is an enlarged detail vertical section through the soldered seam. Fig. y6 is a similar vlew, showing a di'erent shape' of cover.-

In the drawin 1 represents the body of a my 1nvention, the same bein preferab y a one piece seamless drawn bo y. The can body 1 is provided lat its up er end with'an outstanding or right ang e flange 2, the up er surface of which is preferably furnis ed with a solder film or coating 3, fusibly united thereto at the can factory where the can is manufactured. l

The cover 4 is preferably provided with an inwardly or downwardly projectln bead 5, the inner wall'6 of which is adapte to fit snuglyl within' the mouth of the can bbdy and thus register the coverin position in respect to the body. The .cover 4 is further rovided with a laterally projectin seam ange 7, 'the outei` portion 8 of w ich isfolded around and under the outstanding flange -2 of the can body, thus forming it lnto an inturned flange which tightly embraces the outstanding {iange of the can body andsnugly clamps the cover on the can body with lts seam flange 7 in close metal to metal Contact with the solder coated seam flange 2 of the can body.

To enable the can to be readily opened, the cover 4 is further preferably'provided with a projecting lip or tongue 9, preferably at one corner which is carried on the free and unsoldered folded portion 8 independent of l the seam, so that it is not united to the under slde of the seam element 2. by solder or by any 1nterlockin bends, and is folded down against the upright wall of the can body, as will be readily understood from Figs. 1 and 3 of the drawing. Thel cover 4 is further providedwithra score or weakened line 10 extending Yfrom the edges of the tongue 9 diagonally across 'the seam flange 7 and along one end and one or both sides of the cover adjacent to the 'bead 5, as will be read- 'ily understood from Figs. l, 2 and 5 of the drawing.

After the can has been filled with fish or other articles and the cover has been applied and its seam ange'? folded at its outer portion 8 around the outstanding seam flange of the body, thecover is soldered to the body preferably by application of heat v to the outstanding seam flanges of the body and cover, thus fusing the solder film or coating between said seam flan es and thereby forming a hermetically tight soldered seam or joint. `As the seamin flanges of the body and cover are outwar lyprojecting, the soldering may be readily done without in an way injuring the contents of the can.

n ractlsing my invention, I prefer to provi e the seamv Han e of the bodyv with a coating of solder fusi ly united thereto before the can is filled, as thisrenders it unnecessary to apply. any molten solder to the seam flanges of the body and cover during the solder or heat applying operation, and thus'materially simplifiesthe closing of the -cans by hermetically tight solder joints or seams.

In the modification illustrated in Fig. 6, the cover 4 of the can is of a countersunk type and has an u ri ht or countersunk wall closing the soldered edge of said outstandin v ange of the body, substantiall asspecilie 2. In a sardine can, the com ination with a can body having-an loutstanding seam flange, o-f a' cover having an outstanding seam iangesoldered to said seam flange of the body and provided with an unsoldered inturned and free flange at its outer portion folded around said outstanding flange ofA the body, said cover having a projecting tongue carried on the said free and unsoldered folded portion independent of 'the seam, and scores or weakened lines extending from the edges thereof across the seam flange and along the sides and end of the cover.

3. In a sardine can, the combination of a can body having an outstanding seam flange, and a cover having an outstanding seam ange soldered to the seam flange of the body, one of they said flanges being longer than the 'other and extending beyond the soldering and the edge of the shorter flange and being Abent around the soldered edge o the llatter so as to be substantially parallel with the shorter flange, and to inclose the same, thefsaid longer flange beyond the outer edge 4of the shorter flange being unconnected with and'free from the shorter flange; sub- 40 stantially as set forth.
