14 and flange TED STATES PATENT OFFICE.

JOHN G.'HODGS ON, 0F HAYWOOD, ILLINOIS, ASSIGNORTO AMERICAN CAN COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

FRICTION-TOP can.

Specification of Letters Patent.

Patented Sept. 3, 1918.

Application filed October 27, 1913. Serial No. 797,536.

To all whom it may concern:

Be it known that I, Jonx G. Honosox, a citizen of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful- Improvement in Friction-Top Cans, of which the following is a specification.

This invention relates to improvements in friction top cans.

An object of the invention is to provide a can or other form of container, the opening of which is closed by a triple seal, two of the seals being hermetic and the third a friction seal.

The invention furthermore consists in the improvements in the parts and devices and in the novel combination of the parts and devices as herein shown, described or claimed.

In the drawing forming a part of this specification, Figure 1 is a vertical, diametrical sectional view of a can embodying my improvements and Fig. 2 is a top plan view of-the can shown in Fig. 1, the cover being removed.

In said drawing, 10 denotes the can body, the same being provided with a bottom 11 and top 12, the top having a substantially vertical outer friction seat wall 13, horizontally extending gasket supporting shelf 14:, upwardly extending flange 15 and curved inner edge 16 surrounding the usual central opening. A closing cap 17 is provided and the same as shown is provided with a countersunk central portion 18, upwardly extended curved rib '19 cooperable with the curved edge 16 of the top, downwardly extending flange 20 and a horizontally extending flange 21. Interposed between the shelf 21 is a sealing gasket 22 of paper,rubber or other suitable material and interposed between the curved edge 1t} and rib 17 is a second gasket 23. A fr ction cover 24 is provided, the same hav ng a downwardly extending channel 26, the outer wall 27 of which forms oiiperable with the friction seat wall 13 of the top.. The bottom of the channel 26 is adapted. to engage the flange 21 of the cap to thereby press the latter firmly agalnst the gasket 22 and the central portion of the coverengages the rib '19 of the cap to thereby firmly press the cap against the gasket 23. For convenience in removing the cover the latter is provided with the usual form of pryofl' rim 28.

a friction seat wall From the preceding description it will be seen that the can is sealed by means of three dlstinct separated seals, two of which are hermetic gasket seals and the third a friction seal, 1t being understood that the friction between the walls of the cover and top serve to hold the cover in position when the latter is forced home.

Although I have herein shown and described what I now consider the preferred embodiment of my improvement, yet it will be understood that various changes and modifications may be made without departing from the spirit of the invention, and all such changes and modifications are-contemplated as come within the scope of the claims appended hereto.

I claim:

1. A container of the character described including. in combination: a body provided with a. top. said top having an opening therein. an inner gasket supporting edge. a gasket supporting shelf and a friction seat wall: gaskets disposed on said edge and said shelf respectively; a cap adapted to close the top opening and having portions thereof engaging said gaskets: and a cover having a friction seat wall coiiperable with the friction seat wall of the top and provided also including. in combination: a body provided with a top having an opening therein, and

top having an annular channel surrounding the opening the outer wall of said channel forming a friction seat wall and the upper edge of the inner wall of said channel forming a gasket supporting ledge; a cap having a downwardly extended vertical wall. the lower edge of which is bent outwardly to form a horizontal flange; a gasket interposed between the bottom of said channel and horizontally extending flange of the cap; a second gasket interposed between the cap and said gasket supporting ledge of the top; and means for pressing said cap firmly against the gaskets, said means including a cover'having a downwardly extendiln channel. the outer wall of which forms a friction seat wall cooper-able with the friction seat wall of the top and the bottom of which engages said horizontal extending flange of the cap, substantially as specified.

and having a depending flange extending into the said depressed portion of the top;

and a friction COVQI engaging and pressing down the said cap and having a depending annular portion extending into the depressed portion of the top at the outer side of the depending flange of the cap, and having an exterior friction seat wall which engages the corresponding friction seat wall of the top, substantially as specified.

4. A triple seal containen including, in combination: a body having a top provided with an opening, a flange around said opening and a depressed annular portion having at its inner part a vertical wall and at its outer part an interior friction seat wall,

both of said walls surrounding the said flange; a loose cap covering said opening and having a depending flange extending into the said depressed portion of the top; and a friction cover engaging and pressing down the said cap and having a depending annular portion extending into the depressed portion of the top at the outer side of the depending flange of the cap, and having an exterior friction seat wall which engage-s the corresponding friction seat wall of the top; said container having a hermetic seal between the said flange of the top and the cap, a hermetic Seal between the depend friction walls of the cover and top, substantially as specified.

5. A frictiontop container including, in combination: a body having a top provided with an opening, and an internal friction seat wall surrounding said opening; a hard metal cap covering said opening and having a depending flange; and a cover having an external friction seat wall cooperating with the corresponding wall of the top and having a part which bears down upon the said cap, and having a part which bears inwardly against the depending flange of the cap.

6. A container comprising, in combination: a body having a top provided with an opening, a depressed portion, a wall at the inner side of said depressed port-ion and an interiorfriction wall at the outer side of said depressed portion, said walls surrounding the said opening; a hard metal cap closing the said opening and having a hermetic seal on the depressed portion between the said walls; and a friction member arranged to press down on the capand engaging and held down by the said friction wall of the top.

Signed this 9th day of October, 1913, in the presence of two witnesses.
