OF CHICAGO, ILLINGIS.

` BOTTLE cnr.

Application led June v21, 1922. Serial No. 569,956.

To all whom it may concern.'

Be it known that I, WILLIAM C.y BUTTNER, a citizenof theUnited States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented certain newy and useful Improvements in Bottle Caps, of which the following is a description.

My invention relates to improvements in bottle caps and has for an object the production of a valved cap whereby bottled liquid may be charged witha gas after said cap hasv been placed in position thereon, without the removal of said cap.

.The invention has among yits other objects the production of a device of the kind described which will be simple, convenient, compact, durable, reliable, efficient and satis factory for use wherever found applicable.

lMany other objects and advantages of the construction herein shown and described will be obvious Vto those skilled in the art fromthe disclosure herein given.` I

To this end my invention consists in th novel construction, arrangement and combination of parts herein shown and described, and more kparticularly pointed out in the claims.

In the drawings, ywherein like -reference characters indicate like kor corresponding parts, l

Figure 1 is a side elevation of a cap as applied to a bottle;

FigureV 2 is a section ,taken on the line 2 2 of Figure 1;

Figure 3 is a section taken substantiall on the line 3-3 of F igure 1;. y

Figure 4 is a plan view of the cap as seen from its under side;

F igure 5 is a section illustrating a modi-y fied form. of cap; p .y

Figure 6 is a section taken substantially I on the line 6 6 of Figure 5;

Figure 7 is a section similar to that shown in yFigure 5 and having a different or crown form of cap; y

Figure 8 is a section similar to that shown in Figure 2 but illustrating a different or crown form of cap.

Figure 9 is a section similar to Fig. 7 showing Aa slightly different construction;

Fi ure 10 is a sectional view takensubstantially on the line 10-10 of Fig. `9.

In the drawings, wherein Ihave illus trated the preferred embodiments of my in-y vention, 1 indicatesl a bottle or any other suitable container adapted to `have liquids or the like therein. The bottle is adapted to be closed by, a cap comprising an outer member 2, having a flat top 3, and flanged over,

asat 4. The flanged portion 4 is adapted to encircle the neck of the bottle and resiliently engage it thereat. Circumferentially spaced lugs 5 are lformed at'the freeend of the angular flange .4 and extend radiallyin-v wardly thereof so as to engage the threads f formed on the bottle and vhold the capin placethereat The top .of the cap .is providedk with a port or opening 7 therethrough, preferably centrally thereof, and through which the liquid contained in the bottle may be charged withV a gas, in a manner to be hereinafter described. l i.

A sealing member or washer 8preferably of cork, rubber, or othersuitably compressible resilient material, has a central aper* ture or opening 9 therethrough in registry with the opening' 7 through the cap, and also has another aperture l0 therethrough to one side of said central aperture `9, where themember 8 is of rubber, I have found the opening .9 may be omitted if preferred. 'Bef tween the cap and the washer, ther-eis arranged a valve member 11, preferably of rubber or other suitable resilient, elastic, or iiexible material', having an imperforate portion covering. the openings 7, 9 and 10,'vr

but having an aperture therethroughy to one side of said openings. y A In order to chargethe contents of the bottle, a gas under pressure is appliedyto the cap, without remo-ving said cap from the bottle, the pressure of the 4charging gas causing the valve 11 to be pressed inwardly of the bottle at the central portion thereof, whereby said gas will enter through the port 7 and through the opening 12 and pass into the bottlethrough the opening 10. AS soon as the liquid in the bottle has been suffi-k ciently charged with gas, the gas Ypressure,

10o is released and the pressure within the bottle f is sufiicient to press the washer,y and valve y upwardly to close the port k7 and` maintain it closed thus eifectuallyA sealing the bottle.

, In the form shown in Figures 5 and 6 the cap 13 is similar to that shown in Figure A2 eXcept thatk it has a central depressed portion 14 with the port 7 therethrough. The y I recessed ortion 14. In the recessed ortion l@k '14 there is arranged an elastic valve member 15 having no apertures whatsoever therethrough and closing the registering port 7 and port 9 is provided, but oiz such a diameter that it does not close the port 10. Thus it is seen that the recess 14E holds the valve 15 in a predetermined position between the cap and washer. `When the bottle is charged, JChe pressure of the inilowing gas will cause the valve and ,washer to be pressed inwardly permitting said inllowing gas to pass through port 7 and between the valve and capI into the bottle through the aperture 10. As soon as the gas pressure is released the pressure Awithin the bottle will cause the washer and valve to be pressed upwardly into their normal posit-ion, as shown in Figure 5, leffectually shutting off the passage ot gas outwardly of the bottle.

In the form shown in Figure 7, the cap parts are identical with those shown in Figure `5 ,except that the outer member 16 is crimped about its annular flange 17, in the well known manner of crown caps in order to lit bottles adapted to receive such crown ca s.

1fligure 8 illustrates another 'form or' the device similar to that shown in Figure 2, except that in this case, as in that illustrated in Figure 7, the external; flanged member 1S is crimped to lit a bottle adapted to receive a crown cap.

In the construction shown in Figs. 9 and 10, 16 represents the crown cap adapted to be gripped on the; bottle 1 in the usual manner, the cap and valve member 15 being similar to that shown in Fig. 7. However, the washer 19,v which is preferably of cork, instead of having holes similar-to holes 9 and 10, is provided with a slit 20; Then the gas is' discharged' into the bottle in the manner previously described, it will enter through the opening` 7 ,pass by the valvey and through the slit 2O intothe bottle. '1`he pressure ofV the gas, however, when the charging lapparatus is disconnected, will maintain the valve 15 tightly in place and prevent the escape of gas and at 'the same time this pressure exerted against the washer 19 may have a tendency to press the washer sothat the slit is more or less closed. There is, therefore, a very effective sealing, and in case the bottle is laid down, the liquid' against the cork will cause the sameto swell toV a slight extent and the bottle will be even more eiiciently sealed. It is immaterial'as toy how the cap is secured on the bottle or container. Generally this is the preferred form of the device, although in so far as service is concerned` they are all effective for the service intended.

In all the forms or" devices illustrated, it will be seen that there is providedA a valved 'cap having means whereby a charging gas may be directed into the contents of thebottle after said bottle has been capped, said cap having means for automatically kclosing the inlet opening therethrough as soon as the charging pressure has been removed. It is a matter :of preference as to whether rubber or cork is employed as set forth, and the particular securing means or the manner of securing the device on the bottle, or removing the same may be as desired.

Having thus described my invention, it is obvious that various immaterial modifications maybe made in the same without departing from the spirit ofl my invention, hence I do not wish to be understood as limiting myself to the exa-ct form'7 arrangement, construction and combination of parts here-v in shown and described or uses mentioned.

That I claim as new and desire `to secure by Letters Patent is 1. A bottle closure constructed to seat on the bottle at the mouth thereof, and provided with a port5 and exible means fixed in position and operable to permit the passage of gas into 'the bottle through said port and prevent its escape throughv the port from the bottle.

2. In combination, a bottle cap, a washer disk 'therein and adapted to engage the rim o' the bottle, said cao and washer having apertures therethroug u, and a pressure-controlled valve'between said cap and `washer for controlling 'the passage of fluid through said apertures.

3. A cap` comprising a disk adapted'v to be positioned over the end of ay bottle, a washer within said cap for sealing therim of the bottle, and Seli-sealing meansI between saidwasher andl disk whereby luid may be admitted into said bottle without removing said cap. 4, A bottle closure comprising a cap having a port, a washeradapted tov` engage the end o'l' a bottle and having an elongated laterally extending opening therethrough, and an elastic valve, disk intermedi-ate said cap and washer for covering said port and eX- Itending to adjacent the outer-"end ofsaid elongated opening` whereby said bottle may be filled with gas through said openings.

5. A bottle closure comprising a cap having a central port, a washer adapted to engage the end ojt a bottle and having an elongated laterally extend-ing radial opening therethrough, and an elastic valve disk intermediate said cap and washer for coyering said port andV extending to adjacent the outer end ol saidl elongated opening, whereby said bottle may be filled with gas through said openings.

6. A bottle closure com}: risinfr a cap having a central port, a washer adaptedto be engaged at its edge between said cap and the endy of a` bottle and having a. radial slit therethrough extending from the center rto adjacent its periphery, and an elastic' valve disk between said cap and Washer, covering said port and the slit of said Washer to only adjacent its outer end, whereby said bottle will be selr1 sealing, but may be charged under pressure through said openings.

7. In combination, a bottle cap, a Washer disk therein and adapted to engage the rim of the bottle, said eap and Washer having apertures therethrough, and a exible member between said cap land washer for controlling the passage of fluid through said apertures. l v

8. In combination, an apertured bottle crap, an apertured Washer disk therein and adapted to engage the rim of the bottle, and a flexible member between said cap and Washer and imperforate intermediate said apertures for Controlling the passage of Huid through said` apertures.
