Bottle 'l isprovided with a` capV having av metal- .Two typesbf gasket may be provided., to comel inside of shell 8. Grasket .IIL shown. in `Fig...4, is waterproof and gasetight and sufficientlysoft .so` that when shell 8,Uis crimpedovertheneck of the, bottle it 4will vhermetically seal theA contents of the bottle. A suitable material would be rubber, either the natural,..product.or synthetic. .SQftior sealing. yet .the rubber should Abe .sti-1T enough not .to ,bulge out appreciably through While 4sufficiently each otherv by ay hinge I9. qparts' are fastened toeachother by .abolt with ya `winged nut 20. A ange 2l is provided on one .end-of clamping ring I8. 4Within limits said. ring can bemounted `on bottles havingnecksand opening 91due to the gas pressure inthe bottle. The gasket shown in FgfS comprises two parts, the usual cork layer II and a washer I2^above it of Vaffstiif waterproof lpaperI which can however be readily vpierced by the point I3of tube I4. A paraffin impregnated paperwould be-suitable for Washer I2. l

Thedispensing mechanism comprises a` tube I4, having'a tip I5 with -a point I Sjand-slotsjone `of which isV shown at I6. `Tube I4 eisinserted into the bottle through the opening 9 inshell 8, point` I3 piercing the gasket. In Fig. 5,is shown tube I4 afterl it has Vbeen inserted into bottle 'I `and pierced gasket I IJ.

Fitting over the usual Vbulge I'I formed on the neck of albottle with a crimped cap, is clamping ring I8 which consists oftwo `partslattached to The other end ofsaid bulges of -diierent diameters, hinge I9 andthe boltwith wing `nut 1ZEI ,providing adjustability When ring I8l is clamped on the bottle, flange 2I comes under the `lower edge-of bulge I'I preventingsaid ring4 from being' pulled up oi thefbottle. On each part lof -ringl is provided va lug 22. `Engaging thelower edge of each `lug-Risa hooked arm 23. The upper ends ofsaid arms are riveted to -anexternally threadedsleeve 24 which ts slidably over a flange 25 formed on` 1a tubular member 26. A rubber block Y21-1ts `over the lower endwof member .26 under flange 25. Above fla-nge 25,@member 26 isprovided'with an external annular groove 28. A flange formed on the upper edge'of internally threaded sleeve 29 rides in said groove. Sleeve `29 is provided` with capstan'arms 3D. The threading inside of-sleeve 29 vengages with the threading onthe outsidev of sleeve 24. The rotation of sleeve 29 manually by meansof arms 30 may be used to raise or lower sleeve 24 `with respect to` member .26 and its flange 25. When sleeve 29 is rotated so `-asto raise sleeve .24 relatively to i member 26, Athe hooked lower ends of arms 23 pull up on lugs 22, causing-flange 25V topress down rubber block 21 hard against the top of 'shell r8. Lugs 22are T-shaped with a bulb 5I) at-the bottom -of the stern. -This permits the hooks of varms 23.tobe slid horizontally into position on the lugs past the. bulbs, the. heads of the T preventing the arms from going too far.

Tube I4 passesup. through member 26, `a clearance 32 being provided between the outside `of ance 32. and has a block 34 of rubber or the like set said tube and the inside of said member. Above groove 28 is a tube 3| whose bore is in communication with clearance 32. Connected to tube 3| is a hand air pump 33 for forcing air into clear- Above tube 3|, clearance 32 is enlarged expand and tightly grip tube I4 and press against the inside of member 26, effectively sealing 01T the upper end of clearance 32. i

A branch pipe 45 leads off sideways from the upper end of tube i4 and is provided at itsvouter end with a faucet 39, thedischarge from which is controlled by a valve 40.

`In, using my system, tube |4 is set in member 26 so that its tipv I5 is raised up to come inside member 2S. Sleeve 36 is set so that its flange 38 compresses block 34 sufficiently that there can be no appreciable leakage of air or gas from clearance 32 yet the block will permit tube I4 tofbe pushed throughit as desired. Clamping ring |8 is fastened on the neck ofthe bottle by tightening wing nutu2. Y The yhooks on the bottom ofarms 23 are slid over1 lugs 22. Sleeve 29 is rotated to pull up on sleeve 24V and arms 23 compressing rubber block 21 on the top of shell 8 making an airtight chamberabove and around the edgesofopening in said shell. Said chamb er isin communication with clearance 32. Tube I4 is thenpressed downward so that its point i3 passes through opening 9 and pierces gasket In thisv operation no appreciable amount ofggas isvlost from the bottle, whatever leakage there is past tube I4 where itpierces gasket I0 is stopped by block 34. The liquid` in bottle will enter tube I4 through openings I6 (only one being shown) in tip I5. If there is sufiicient gas pressure inthe bottle the liquid will rise to valve 40. vOperating valve 40 will allow liquid to be dischargedfrom faucet 33. If the gas pressure is notsufiicient pump 33 is used to get up suiiicient pressure. Whenr a quantity of liquid has been discharged from the bottle and no Vmore liquid will come out rwhen valve 4Q is opened, pump .33, is operated again. Pump 33Vforces air intQthe bottle through clearance 32, opening 9 and Vbetweenthe pierced gasket and tube I4 where it passes through. With the air pressure thus obtainedthe liquid is discharged from faucet 39 when valve 4 0 is opened.

The type of apparatus shown in Fig. 6 is especiallyV/adapted for bottles having thin necks closed Vby corks instead of crimped caps. The partiularbottle 4| shown has no bulge on its neck only alip I42st its top. To suit this condition clamping ring I8 `is set on the neck with its nflange Zion top comingV under lip 42. The

ing the cork into the bottle and out of the way. From here on the operation of the apparatus is the `saine as described above for Figs. 1 and 2.

While the crimped cap, oiten called a crown cap, is my preferred form, other types of cap, with a gasket inside their outer shell, may be used such as a screw cap with the neck of the bottle correspondingly threaded. A screw cap lends itself readily to having its tough outer shell of other material than metal such as a phenol condensation product.

The term bottle as used in the claims is intended to be broad enough, except where it is clear by the context that a bottle is meant, to cover in addition to the usual glass bottle, a gas- `tight container. with some form of bead, enlargement or irregularity with which the adjustable detachable clamping ring can engage. I claim:
