7 SPECIFICATION forming part of Letters Patent No. 795,125, dated July 18, 1905.
Application filed NOVG IIB 21, 1904:. Serial No. 233,558.
To ml] whom it may concern:
Be itknown that I, JOHN G. I-IoDGsoN, acitizen of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented anew and useful Improvement in Key-Opening Cans, of which the following is a specification.
My invention relates to improvements in key opening cans.
The object of my invention is to provide a key-opening sardine-can having a drawn or seamless body and adapted to have its top head or cover sealed and secured to the body after the can is filled by a double seam, which may be manufactured at small cost, which may be readily and certainly opened with a key, and in which all parts of the can may be free from scores or weakened lines, such as have heretofore been customarily employed in key-opening cans.
My invention consists in the means I em ploy to practically accomplish this important object or result-that is to say, it consists in a sardine or other can having a seamless body, provided at its month end with an outwardlyprojecting integral flange folded or adapted to be folded into a double seam with the marginal flange of the countersunk cover, and provided at its other end with a sectional or partial integral head and with a marginal inturned integral flange surrounding this end of the can-body and extending across the sectional or integral head of the can in combination with a removable head having a marginal flange or rim soldered or adapted to be soldered to the inwardlyprojecting integral flange on the body and furnished with an integral tongue adapting this removable "head to be readily removed by winding the same around a key.
My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown or described.
In the accompanying drawings, forming a part of this specification, Figure 1 is a plan view of akey-opening can embodying my invention. Figs. 2 and 3 are cross-sections on lines 2 2 and 3 3, respectively, of Fig. 1; and
Fig. 4 is a plan view of the seamless body of the can.
In said drawings, A-represents a drawn or seamless can-body, the same having at its mouth or filling end an integral outwardlyprojecting flange a, interfolded into a double seam a, with the marginal flange 7) of the countersunk head B at the mouth or filling end of the can-body. The seamless can-body A has at its other or opening end an integral head section A and an integral inturned marginal flange (L2. The partial or sectional integral. head A preferably extends over about onethird or one-fourth of the surface of the can and leaves a large opening A, through which the sardines or contents of the can may be removed when it is opened. The integral sectional or partial head A is countersunk and the integral inturned flange c extends at (0" across the end of the integral, partial, or seetional head A. The integral head-section A has a raised flat marginal rim a, which forms a continuation of the inturned flange (4 around this end of the body. The upright wall a of the countersunk head-section A extends all around this head-section A and is of course integral with the body A. D is the removable sectional head, the same having an integral tongue D and a marginal rim or flange (Z, bounded on the inside by aflange or shoulder 0?, which fits inside the opening A This countersink or shoulder d causes the tongued. and removable head or cover I) to be readily kept in position on the seamless can-body A during the operation of soldering the same thereto. In opening the can the integral tongue D is inserted through the slot of the key and the removable sectional head D removed by rolling or winding the same around the key, thus ripping the soldered joint (.Z, which unites the head or cover section I) to the soldering-flange (0 (1 of the seamless body A.
1. In a key-opening can, the combination with a seamless canbody having an integral countersunk head section extending over a portion of one end of the can and a large opening for removal of the contents of the can, a marginal integral soldering-flange extendii'ig around said opening and along the integral head-section, anda removablehead or top provided With a tongue and a soldering-flange, substantially as specified.
2. In a key-opening can, the combination With a seamless body having an integral head extending over a portion of one end of the can and having an inwardly-projecting solderingflange extending around said seamless body and along the edge of said integral headsection, of a removable countersunk head fur nished with a tongue and united by a solderjoint to said seamless body, substantially as specified.
3. In a key-opening can, the combination with a seamless body having at one end ahead secured thereto by a double seam and at its opposite end an integral countersunk headsection extending over a portion of that end of the can, and provided With a large opening for removal of the contents of the can, and a marginal flange extending around said opening of a removable head provided With a tongue and a flange soldered to said marginal gaggeon the can-body, substantially as speci- L. In a key-opening can, the combination with a seamless body having at one end a head secured thereto by a double seam and at its opposite'end an integral countersunk headsection extending over a portion of that end of the can and provided With a large opening for removal of the contents of the can, and a marginal flange extending around said opening and a removable head provided With a tongue and a flange soldered to said marginal flange on the can-body, said seamless body having an integral raised flat marginal rim a forming a continuation of said marginal inturned flange and flush therewith, substantially as specified.
