CLOSUREFOR REcE 'TAcLEsf Application filed January 18, 1924. Serial 1T6. 686,977.
Toall whom it may concern."
Be it known that I, Htion S. BRADY, a citizen of the United .States, residing at lVheeling, Ohio County, 'West Virginia,
' t have invented a new and useful'Improveclosure embodying my invention 1n the mouth thereof; Fig, 2 is an enlarged sectiolf showing the position of the closure after the jar'has been vacuumized or the closure otherwise applied; and Figs. 3 and 4 are sections showing the application of my invention to a cap with a crimped on band and to a screw cap, respectively.
My invention relates to the sealing of j-ars, tumblers, bottles and other receptacles, by applying thereto caps or covers and gaskets, which are held in position by atmos- My invention in particular comprises a gasket applied ,on-a seat within the mouth of the receptacle and a cover or cap having a bearing againstthe inner surface of the gasket and extending upwardly and outwardly over the gasket to substantially the periphery of the recep VVhen'the cover'has been applied, the atmospheric pressure upon the central .portion of the cover, which has a domeshaped or raised surface, forces the cover against the inner surface of the gasket, wedgingit tightly against the seat in the mouth of the receptacle, thereby forming an effective seal. My invention also com- :prises the various features which I shall hereinafter describe and claim.
Referring to the drawings, 2 indicates a receptacle, preferably of glass or similar material, having within its mouth a recess or seat 3, the face 4 of which has a slight draft to facilitateapplication and-removal of the closure. Arranged in the seat 3 is a rubber gasket 6, preferably of rectangular shape. Thecover or lid has a dome-shaped or raised central portion 7 the normal diameter of which is preferably slightly greater than that of the inner perip eral surface of the receptacle immediately below the recess or seat 3. Extending upwardly from the periphery of the central portion 7 of thecover at an abrupt angle is an annular flange 8; which bears against the inner face 9 of the gasket 6. From the upper edge of the flange 8 a peripheral lip 10 extends outwardly so that its outer edge is approximately flush with the periphery of the receptacle. The outer edge of the lip 10 may, if desiredybe' formed in a bead 11 r to eliminate the raw edge and reinforce the cover.
In applying the closure to the receptacle the gasket 6 may be placed in-the recess 3 or'u'pon the outer face of the flange 8 of the cover, and the cover isthen placed in the position shown in Fig. 1. The receptacle 2 may then be vacuumizedand the atmospheric pressure Wlll draw down the domeshaped or rais'ed central portion 7 of the cover, which will cause the enlargement of the diameter of such portion and force the flange 8 of the cover against the lower portion of the face 9 of the gasket, and the lower portion of the gasket tightly against the lower portion of the face 4 of the recess 3', thus causing an effective sealing of the cover against the gasket 6, and
the gasket against the surface 4 of the recess. The intersection-12 of the central portion 7 and the flange 8 of the; cover is the point at which :the' greatest expansion 'of' the cover occurs, by reason of the enlargement of the diameter of the cover thereat as a result of thedepression of the central portion 7 of the cover, as is shown in Fig. 2, in which the arrow indicates the component of force. It follows that those portions of the gasket 6 which lie nearest such intersection will be subjected to. the great est amount of pressure, with the result that such pressure will tend to cause the gasket to assume the shape of the wedge as is shown in Fig. 2, in which-the angle between the central portion of the cover and its flange tends to become more acute.
When the cover has been applied a slight space is preferably left between the lip 10 and the top surface 13 of the receptacle, so as to permit the insertion of a tool, and thereby provide for ready breaking of the seal and the easy removal of the closure.
In Fig. 3 I have shown my invention applied to a cover 15 having a crnnped on band 16 which engages the lip -17 of the cover and the shoulder 18 on the exterior of the receptacle. The band 16 assists in holding the cover in position when it has been applied and in maintaining intact the seal between cover, gasket 19 and receptacle.
In Fig. 4 I have shown my invention applied to a jar intended for a screw top 20. As the screw top 20 when applied presses the upper lip 21v of the sealing-cover 22 downon the top surface of the gasket 23, it
forming part of said cover projecting outwardly from said flange covering the gasket and the upper edge of the receptacle and acting as a retainer for the gasket; the cenwill increase the'pressure upon the gasket tral portion being adapted to be depressed and thus render the 'seal between cover, gasket and receptacle more efl ect1ve.
Closures embodying my invention may also be applied without vacuumizing to re ceptacles with hot contents, since the cooling oflof the hot contents of the receptacle will reduce the pressure within the receptacle to' a suflicient extent to enable the normal atmospheri c pressure'on the exterior of the closure to press down the dome-shaped or raised central portion 7 of the cover and force the flange 8 outwardly against the gasket, and the gasket against the seat 3,
and thereby eflectively seal the receptacle.
The terms. and expressions which I have employed are'used as terms of description and not of limitation, and Ihave no intention, -in the use of'such terms and expres' sions, of excluding any mechanical equivalents of the features-shown and described. or portions thereof, but recogn ze that various structural modifications are possible within the 'scope of the invention claimed.
What I claim is: I
1. In aclosure for receptacles, a receptacle having a mouth; a flexible metallic cover having a dome-shaped central portion and an upturned flange extending upwardly 'from the periphery of the centralportion; a gasket seating on the outer face of said flange in the region of the juncture between 7 the central portion and flange and engaging the rece tacle within its mouth;'the central portion eing arranged upon the application of external pressure to expand its peripheral portion and thereby force the gasket firmly against the receptacle.
2. In a closure for receptacles, a receptacle having a mouth; a flexible metallic cover having a dome-shaped central portion; an upturned flange extending upwardly from the periphery of. the centraltacle having 'a' mouth; a flexible metallicv cover having a dome-shaped jce-ntral portion and a-flange acutely angled with regard to the central portion and extending upwardly from the periphery thereof; a gasket gasket engaging the exterior of said flange in the f region of the juncture of said central portion and. flange andhaving a bearing in said mouth; the central? portion beingarranged to be depressed by atmospheric pressure and to exert through the flan e a pressure on the gasket and deform it into wedge shape i in cross-section; the angle between the central portion of the cover and itsiflange 1 is applied.
4. In a closure for receptacles, areceptacle having a mouth; a flexible metallic cover having a dome-shaped central portion and an upturned annular flange extending tending to become less acute as the pressure upwardly from the periphery of the central portion; a gasket seating in said mouth and bearing on the outer face of said flange in the region of the juncture between thev central portion and flange; t e cover also hav-" ing a lip extending radially from said flange forming a reinforcement for the coverand a retainer for the gasket; the central portion being arranged to be depressed by atmospheric pressure and to exert through the flange a pressure on th gasket to effect sealing of :the receptacle; and a supplementary holding member having a bearing on the lip of the coverand on aprojecting portion on the exterior of the receptacle.
