Applicatiomfiledi Decemben- 26, 192 5. SeriahNo. 77,744 V v My, invention relates tofcontainercoyers and processes, -I for: producing the same ,and:

is desirous of obtaining 'accessfto the con-g Pa ticul r y: to covers, capable f h metically sealing,

processes for producing the same.

tached; to a container',.; and: so constructed that its plurality of hermetically sealed members}. may be re dily separated when it .tainer contents.

Container covers of the character de scribed, and especially those adapted for use with preserved food products, must be absolutely air-tight even under, considerable outward pressure, and must be capable of being readily opened when desired. I They economic and efficient and hermetically sealed cover for containers. I

My device comprlses a flanged central member and an outer member having an:

opening of less diameter than the diameter of the central member, the flange being folded into an S-shape with the peripheralpprtions of the outer member opening being within the curves of the S-shaped flange.

The several steps of production of my device, and the device itself, are fully eX-l plained in this specification with its, accompanying drawings which will indicate the novelty, usefulness and effectiveness of my device.

In the accompanyingdrawings illustrat ring my invention, similar parts are desigof my device. 7 s

The particular form of the device of'my invention shown in the accompanying drawe ings comprises two removably attached members 10 and 11. The central member 10 has a downwardly extended flange 12 around its The member ,jhas

The formation. of I the completed is 10 buttof less diameter-khan the diameter oi opening of. the ,member 111-. as. shown gin ur 4-. h rert oi otit e I ge e w h ih .1.- i ;.then pu vo t r y as shown in Figure 5to form a recess in which the inner portion of the member 11 is i positioned. The portion of the flange 12 tween the flange 12 and the member 11 is above the member-11 is then spun outwardly f made complete by pressing the two curved positions of the'flange 12into close abutment with the member 11. The operation shown in Figure 6 may sometimes be omitted and the complete closure between the flange '12 and'the member 11 accomplished by the operation shown in Figure 7, or the two spinning operations of the flange 12 shown in Figures 5 and 6 may be performed si-' multaneously.

It is advisable that member 11, in order to assist in the production of ashermetical jointure between the flange 12*a'nd the member 11. i The cover can then be permanently attached to a can, or receptacle, 15,-by any proper means. j

In order to open the cover, thus'formed, a pointed flat instrument, as a screw driver} so; I

a proper cementitious materlal'l be placed upon'both sides of the. m

chisel; or other suitable device--16 is: forcibly inserted between theflange12- and the mem ber ll and usedas' a lever for displacing the sealing members, allowing of the removal of'the central member 1'0.-

Another suggested means of opening the cover is to spot welda ring 17 to the member 10 near its periphery, the ring 17 carryit which will disengagethe sealing. members.

"From the above, it willvbe noted, thatthe- I "periphery of the opening of the outer mem- [ber 11 is tightly wedged within the S-shaped flange-12 of the, central member 10. 1

I do not limit myselfito the particular I size,shape, number, or arrangement or material of parts,nor to'the particular steps of V procedure shown and described as these are given simply as a means for clearly describ- 7 mg my invention.

. What I claim is :V V

In a container cover device capable of attachment to the sides 'of a container, 'in' combination, a side member capable ofattachinent to the sides of a container and have 7 ring an opening therein; and a removable cover of greater diameter thanthe side member opening, the outer edge of which is bent downwardly, inwardly, downwardly and outwardly forming an Sshaped member, the cover bemg positioned externally of a container to which the device is attached,

ing an opening therein; a removable cover of greater diameter than the side'member vopening, theouter edge of which is-bent downwardly, inwardly, V downwardly and outwardly forming an S-shaped member,

the cover being positioned externally of a container to 'which the device is attached, the aperture defining edge of the side mem-.

her being positioned within and hermetically sealed'to theS-shaped member and the S-shaped member being "so positioned with respect to a jointure between the side memher and a container side, that a lever placed.

within the S-shaped member will fulcrum upon the jointure for the outward removal of the'cover by means of force applied thereto. 7 r V Signed at New York city in the county of -New York and Stateof New York this 21st day of December, 1925.
