1 nIsraNsme car ron BOTTLES.

The present invention relates particularly to dispensing caps for bottles containing carbonated liquid, such as, 'nger ale and the like. When mixing sue a liquid with a base, it is well recognized that a much more palatable drink results if the bottle containing the liquid is well shaken and the liquid forcibly dischar ed in a fine stream under the impetus of t e liberated gas.

su sequent to removing the sealing cap, and

- while the new cap is readily apphcab e and removable, it is so constructe as to form an air tight and rigid connection with the neck of the bottle when in position for o eration. Upon adjusting the cap the bott e may be shaken to liberate the gas, and valve means are rovided so that subseao quently the liquid may be dispensed as neede One embodiment of my invention is illustrated in the accompanyin embodiment being merely il ustrative and in u nosense restrictive. In the drawings Figure 1 is a top plan view of the new cap; Figure 2 is a vertical section on theline 2 -2 of Figure 1, the cap being shown in connection with the neck of the bottle, and Fig- Q ure 3 shows the cap as seen from beneath.

' Referring to drawings, 10 represents the mainbody of the cap, which, as may be 'readily seen from Figure 2, is cupped to produce an annular flan e 11, the margin of a5 whichis desi ed to taround the bead 12 of a standar bottle. For somewhat more than half of its circumference the flange is extended downwardly, as at 13, and bent to fit under and ip the bead 12. Elements m 10, 11, and 12, ust described, are preferably formed integrally of suitably heavy spring metal, and for ease of manipulation the extremities 14 of flange 13 may be bent out- -wardly (be 0nd their semi-circumferential slit inwardly, as at 15 (Figures 2 and 3). Seated in the upper portion of cap 10 i a washer or packing element 16 of such configuration as to secure a snug) fit. The ele- 5o ment 16 is preferably of rub er, this material havin the necessary resiliency and du- 'rability, a though an other suitable material may be used. T e mass of this washer is such that, when the cap 10 is adjusted in operative position, its lower margin will be 'municates by a duct '20 with a liner and The cap according to my invention is d esigped to be applied to a standard bottle drawings, thistles-in other words, it-is a durable accescompressed to"form an air tight packing. Asshown in Figure 2,'w-as her 16 is provided with an axial bore 17 registering with a rforation 18 in ca 10. The bore 17 is enargedas at 19 an this enlargement comspout 2lri idly secured in an aperture in the cap. The inner cross section-pf element 21, or at least o'fits orifice, is very small so as to deliver an extremely fine stream. The inner portion of element 21 servesto hold washer 16 in proper position and to prevent the blocking of the duct upon compression of the washer. 4

A valve disc '22, mounted on a stem 23 which extends upwardly through bore -17 and perforation 18, serves to cover enlargement 19. Stem 23 has a button 24 mountedon its outer extremit and interposed between the button an cap 10 is a return spring 25. V

It will be seen that under normal conditions disc 22 will prevent the escape of any gas through duct 20 while upon depression of button 24, duct 20 will be opened, and upon inversion of the bottle, the contained 1i uid will be forcibly dischar ed.

t is to be emphasized that t e cap according to my lnvention is ada table for repeated application to standar beverage botsory. I also call attention to the fact that the attachment means are substantially positive; that is to say, pure friction is not relied upon, but a positive gripping action is present. It will also be noted that the pressure within the bottle will tend to seat th valve disc the moresecurely.

While I have necessarily described my invention in some detail, it will be recognized as that'various changes within the range of mechanical skill w1ll sug est themselves to those skilled in the art. t is to be understood, however, that I do not limit myself except as in accordance with the following claim.

I claim: A cap for cha'rged-bevera bottles of the type having a top peripherzfl, bead, said cap comprising depen ing opposed gripping means, said gripping means being engageable under opposite portions of said head upon forcedmovement of said cap substantially parallel to the bead, whereby said cap is retamable inoperative relation to said bot- '110
