In the drawing:

Fig. 1 is an elevation of a fluid container and a dispensing device incorporated therewith;

Fig. 2 is a vertical section, on a larger scale, showing in detail the structure of the dispensing device as incorporated upon a fluid container; m x x.^{ls a vertical} section similar to Fig. 2, and illustrating another form of device; and ,,,®¹?· V^{s a vertical} section similar to Fig. 2, and illustrating still another form of device.

In practicing the invention a dispensing attachment 10 is shown mounted upon the upper portion of a fluid container 12, and includes a casing! 3 haying depending inwardly crimped flange ^^ldns. ^,5.· ^One or more of these sections is provided with an extension 16 to facilitate prying of the casing from the container. Shoul40 ανΓοΓ i“m^{ed by crim}Pm&amp; the flange sections 4U are adapted to snap below the lower flange edge ! 8 of a container cap ί 9, that is employed to seal the mouth 20 of the container.

A resilient annular washer 22 is disposed in the casing against its uper end wall 23 which is slightly spaced from the top of the cap 19. The spacing between the cap and end wall 23 is such that the washer is compressed when the flange shoulders 17 are snapped into position upon the lower edges of the cap ί 9.

A cup shaped portion 25 is pressed outwardly in the upper wall portion of the casing 10 and is provided with a central opening 26 through which a metallic sleeve 27 extends slidably and with so much play as to permit tilting or universal movement of the sleeve in the opening. The upper end of thesleeve 27 has an outwardly and downwardly Γ.11Υ*ηοΗ anmilnw λλ__· « * ~ _Λ -----------1 engages the upper end of a yieldable outer sleeve 30 composed ----------- sucn as compressible rubber. The lower portion on the rubber sleeve 30 5 nnrH^^P« ^SUriaCe °^{f the CUP} Shaped _________ . . --------3 is thus held under closure for the casing opening 26. A series of lateral openings 35 are formed in the sleeve 27 ¹³ adjacent the junction of the sleeve proper and its Af JL^{and provides f}°r the passage or fluid through the sleeve when the valve member is opened. The lower end of the valve member „^a® ? downwardly pointed projection 36 located substantially at the center of the cap 19.

Upon mounting the casing 10 upon the container cap 19, the sleeve 27 can be manually forced downwardly, thereby compressing the resilient sleeve 30 and forcing the projection 36 through the cap 19 to form an opening 37 therein, since, this type of device is designed for application to fluid containers in which the fluid is ®®^aled under pressure, the fluid is immediately released into the casing cap. As soon as the cap 19 is pierced, the fluid under compression in the container is free to pass into a chamber 38 formed by the casing, but the fluid is prevented from leaking by means of the washers 22 and 33. By manually holding the container, as indicated in Fig. 1, and tilting the sleeve 30 from its vertical position, or away from axial alignment with the container, the valve member 32 is unseated, or partially unseated; whereupon the fluid in the container is free to pass through the openings 35 and through the sleeve 27.

°^{f C}x°^{urse be} understood that in drawing fluid from the container, the user turns it to direct the mouth of the sleeve downwardly. That is the container is turned after the manner of pouring fluid therefrom. The contents of the container can be directed into a drinking glass, or the like under the influence of the gas under pressure which was stored in the container when the latter was filled. As soon as the sleeve 27 is released from its tilted position with respect to the contamer, the resilient sleeve 30 closes the valve member 32 against further discharge of the fluid in the form of the invention shown in Fig 3 the sleeve 27 and casing 13 are substantially the’ 55

8,004,018 same In construction at those previously described, and hence, similar reference characters are employed to designate corresponding structural parts. In the construction shown in Fig. 3, 5 however, the washer 33 is omitted, as such, and the lower end of the resilient sleeve 30 is formed with a lower flange 40 and adjacent groove 42 that receives the casing edge forming the opening 26.

When the sleeves 27 and 30 are tilted in the manner described above, the valve member 32 is unseated from one side of the flange 40 to permit the passage of fluid from the casing through the openings 35 and through the sleeve 27.

In this arrangement it is not necessary that the lower flange of the casing be crimped entirely about its circumference, but spaced sections 43 having shoulders 45 substantially the same as the sections 15 are provided to operate in substan20 tially the same manner.

In Fig. 4, a portion 50 of the device which corresponds to the casing 13 is composed entirely of rubber, or other suitable resilient material, somewhat in the form of a nipple and is provided with 25 an inner annular shoulder 52 which is resilient and can be stretched over the cap 19 until it is anchored upon the lower edges ¢8 thereof. A second annular shoulder 53 rests upon the marginal portion of the cap 19 and a cylindrical wall 30 55 joining these shoulders is slightly stretched and remains under tension while the shoulder S3 provides a seal about the cap.

The upper portion 56 of the resilient device 50, which is shaped like the rubber sleeve 30, is pro35 vided with an inner sleeve 57 formed of relatively rigid material and having at its upper end outwardly and downwardly turned flanges 58 engaging the upper end of the sleeve portion 56. A valve member 59 is screw-threaded in fluid-tight rela40 tion into the lower end of the sleeve 57 and is provided with a series of lateral openings 60 to serve the same purpose as the openings 35. The valve member is normally pressed into fluid-tight relation against an annular shoulder 62 of the 45 inner wall of the cap 50 and is provided with a lower pointed projection 63 which serves the same purpose as the projection 36 in puncturing the cap 19. In utilizing this construction the sleeve 57 is tilted in the same manner as that described 50 above to unseat the valve member 59 from the shoulder 62, thereby providing free outlet of fluid from the interior of the casing through the sleeve 57.

From the foregoing description it will be ap55 parent that the invention is adapted to be applied to any type of bottle, and although it is particularly adapted to be used in conjunction with a bottle having a sealing cap 19, it is apparent that the cap might be removed and the device used 60 upon an ordinary unsealed bottle.

Although several forms of the invention have been shown and described in detail, it will be apparent to those skilled in the art that the invention is not so limited but that various changes may 65 be made therein without departing from the spirit of the invention or from the scope of the appended claims.
