s eles.

The object of my invention is to provide a sheet metal sardine, can of a simple and ellieient' Construction, adapted to be rapidly and cheaply manufactured, and to have its cover soldered on the body after the can is filled without danger of produein leaks in the soldering operation. or of snort-hing or injuring the contents of the tan. and which also may be conveniently opened.

My invention consists in the means I employ to practically accomplish this object or result, the same comprising certain novel constructions of-parts and devices and novel combinations of parts and deices herein shown and described and more partirularly specified in .theg laims.

In the accompanying drawinglorming a. part of this specification, Figure l is a pew speetive view of a sheet metal can for saw dines or other articles embodying my invention. Figs. 2, 3 and 4 are seetions on lines 2--2. 3 3 and 4 4 respectively of Fig.1. Fig. :3 .is a plan View of the body of the can before the cover is sean'uiwil and soldered thereto. Fig. l is an enlarged sew tion on line 6 6 of Fig. i

In the drawing. 1 represents the body of a sheet metal sardine can embodying my invention, the same being preferably .a one piece seamless, drawn body of generally reetangularshape with rounded corners 2 unit ing its upright sides 3 with its upright ends 4. The integral bottomh of the body is preferably upwardly paneled or counter sunk, the marginal walls 6 of the countersink serving to materially strengthen the body.

The can body 1 is provided at its upper end with an outstanding or right angle seam flange 7. This seam flange 7 of the body has relatively .wide portions at the transverse and longitudinal sides of the can body and relatively narrow portions 9 at. the four rounded corners of the can hotly. The outstanding or right angle'seam flange 'firmly clamping and 7 of the ean body provided with a solder film or (eating 1t. on its upper surface; this routing heir-r9; tusibly united to the tin (out surface ol the ("an ll()ll V flange at the factory where the run is inamllactured and beforethe run tilled or the cover applied thereto,

lhe purpose of ll solder Coating 10 is to enable the seam tlal'ige of the eoi'er to be soldered or tusihly united to the seam flange of the can body by a simple fusing operation or subjection of the. seam flanges of the (an body and cover to the neeessary heat to fuse the solder film or coating 10.

Th cover ll Whieh is of tin plate. the same as the body of the can, is provided will a marginal seam flange 12 to lit flat. against and in snug metal to metal eontaet with thrsolder coated seam flange. of the can h tly. The cover ll is also provided with a downwardly extending registering wall 13 adapted to tit snugly within the. upper end or mouth portion of the can body to reirister the cover inposition on the can boil eralily be f rmed by providing the cover with downwardly projecting head 14 instead of by oountersinlting'the cover.

The ela-tively wide portions 8 of the seam flange 7 at the longitudinal and transverse sides of the ean body are folded over the seam flange of the (.(Yitl' after the (.2111 has been filled and the cover applied, thus holding the seam ilange of the (over in tight (-lose metal to metal eontaet with the SOltlQl coated seam flange 7 of the ean body. As the told 15 of the van hotly seam flange 7 firmly embraces the seam flange of the rotor for the greater portion of its extent, that is to say, excepting: at the rounded corners. the seam flange of the cover is very firmly ("lamped to the seam tlange of the body during the soldering or fusing operation, and thus enables the cover and body to be soldered together by perfectand hermetieally tight solder joints or seams free from pin holes or leaks, and this with certainty and uniformity. And as the seam flanges of the body and cover are outstanding or outwardly projecting, the some may he subjeete-cl'to the necessary heat to etleot fusing of the. solder withoutdanger of seorrhing or injuring the contents of the can.

To enable the can to he readily opened by rolling oil the cover by means of a key in of the ean body flange does not embrace the rover flange at the rounded corners of the can, but only at the transverse and longitudinal side portions of the can body, the can is thus adapted to be readily opened by rolling the cover about; a key without the necessity of providing the cover with any scores or weakened lines. The cover, however, may, if desired, be provided with a marginal score or weakened line extendingtroin the side edges of the key lip or tongue 16.

After the can has been filled with fish orother articles and the cover has been applied and the outer fold portions 15 of the can body seam flange 7 folded upwardly over and around the outstanding seam flange 12 ol the cover 11, thus firmly clamping the seam flanges of the body and cover together and holding the same in close metal to metal contact. the rover is then soldered to the body, preferably by application ot'heat to the outstanding seam flanges of the cover and body, thus fusing the solder film or coating between said seam flanges and thereby forming a hermetically tight soldered seam or joint.

In practising my invention, it is preferred to provide the upper surface of the seam flange of the body with 'a coating of solder tusiblv united thereto before the can is filled as I consider this preferable either to coating the under surface of the seam flange of the cover with the solder or to applying molten solder to the seam flanges of the body and cover during the'soldering or heat applying operation. I11 my invention, however. the cover may be soldered to the (an body in any known or suitable way.

As the outstanding seam flange of the can body has relatively narrow portions at the rounded corners of tljmreetangular sardine can, and as these relatively narrow portions are not folded or clenched upward over and around the outstanding seam flange of the cover, this obviates all tendency to cramp the corners of the can, and also all tendency to separation between theseam flanges of the body and cover at the rounded corners. such as would be liable to result if it were at tempted to fold a body flange of even width upwardly ver and around the cover flange at the. rounded corners of the can as well as seam flanges at the rounded corners of the can are. relatively short.

I11 my invention also, the narrowing of the seam flange of the body at the rounded corners of the drawn can body also results in material saving of stock, as it materially increases the size of the scrap portions of tin plate between the corners of adjacent cans out and drawn from the sheet of tin plate.

I claim z 1. In a sheet metal can, the combination with a rectangular can body having longitudinal and transverse upright sides and rounded corners and provided at its month end with an outstanding seam flange having relatively wide portions at the longitudinal and transverse sides and relatively narrow portions at the rounded corners of the can body, of a roll top sheet metal cover having an outstanding relatively narrow seam flange eorrespomling to the relatively narrow portions ot said body flange, the relatively wide portions of the can body flange having folds embracing the "over flange, said cover flange having an integal tongue foldd ed under the relatively narrow portion of the body flange at one of the rounded corners of the can, substantially as specified.

9. In a sheet metal can, the combination with a can bodyhaving an outstanding integral seam flange extending at substantially right angles to the sides of the can, said flange having wide and narrow per tions, of a roll top cover provided with a tongue and having an outstanding seam flange of substantially uniform width around the entire edge, the cover'flange and narrow portion of the body flange being substantially of the same width and soldered together entirely around the can,

the wider portion of the body flange being bent over and around the cover flange, whereby the folded over wide portion of the body flange is adapted to firmly clamp and hold the cover and body seam flanges 120.

in close metal to metal contact and assist in preventing the same from springing apart, substantially as specified.

3. In a sheet metal can, the combination with a drawn, rectangular can body hav- 12a 111g rounded corners and having an integral outstanding seam flange provided with: 'a narrow and wide portions, the narrow por tion being located at one corner of the can body, of a rectangular roll top cover haviuig 1m unfing: swam flange, being pmvid v mum (i HINT-WW p the wide 101M01 0f the tmdy seaw 3. being: UHF Hg) and ir fhe (over fin: mm and both of sub mm width at Hm'cnrners, 05 'nm'iug wide portions i(1% umn'xnodiaiu the corners, xpuz-i xmw'lmng fuided mm and 'irx'ifl' and body scum ml! \rumiwt and mum from spring a spcvified.
