CAN-CLOSURE.

No. season.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed January 18,1906. serial in. 296,600.

To all 'uihovn it may concern:

Be it known that I, Eminx o ,lEoKAin'r, a. citizen of the United Stan's and a resident of N ew Rochelle/Westchoster county, State of New York, (whose post-oflice address is Bill East Forty-second street, borough of Manhattan, New York city, NewvYorlg) have invented certain new and useful Improvements in Cair-Closures, of which the following is a specification.

I My invention relates to means for closing cans or receptacles for liquids, or solids in powdered form, in such a manner that the said cans or receptacles shall be closed air-tight and water tight, and may at the same.

, thereto. As shown in this instance the inner edge portion of the part 13 is bent, first downward, and then upwardly, so as to form a groove C, and is then bent.inwardly at D and lownwardl v, so as to provide a frictional Contact portion E.

The sheet metal cap F is provided with a wall G, an outwardly bent portion H, a backward turn or bend I and a downwardlyextending spring portion K.

In Fig. 2 the can is shown closed, with the cap in place. It will be seen that the cap is'lrictionally held by the Contact of its wall G with the part E 01 the can, and of its spring piece K with. the inner wall of the groove 0 on the 01.11. The position of the spring portion K is indicated in dotted lines in Fig. 3. The relation between the positions respectively assurned by the part K is shown in an exaggerated manner for the sake of clearness. i

It will. be noted thatthe lower edge of the portion K is not headed or upturned as in many cans now on the market, the necessary point oi application or the lever "used in opening the can being located, at the upper V edge, thus leaving the entire portion K springy.

When the parts are properly constructed, the can,

when closed, will be watertight andairtight. The cap may be removed by prying it up by means of a coin, in the usual. manner, the coin being fulerumed 'on the outer edge of the can, and bearing upon the lower portion of the bend I.

The structure of my can-closure may be varied in many details without departingfrom the spirit of my invention as expressed in my claims. l

Therefore, without limiting myself to theconstruction shown and-described or enumerating equivalents, I '1 claim 1. A can closure comprising a lid, a cross section of the edge of which lsshaped like an inverted that the 'outer arm of which is located 'a'springy-flange, the said U-shaped part being adapted to fit over an annular rim on the top of the. can having a simllaricross-section, producing thus a double annular sealfwith the edge only of: the outer springyjlange of the lid fitting against -a rigl d flange of the rim on the top of the can, substantially as, described. 2. A can closure comprising-a lid across-section of the edgeof which is shaped like'an inverted U, at the outer arm of which is located a springy flange, thesaidfU-shaped part being adapted tofit over a similnr'annular rim on the top of the can sothatjhe edge only of the spriligy flange of the can fitslagninst n rig id flange on the. can and the rigid flange offthe cover, fits against the innermost free flange of the'can, substantially as described.

In testimony'whereof I have'signed rny name to this specificzitiondn the presence of two subscribing witnesses;

EDMUND ECKART.
