The dispenser D rests uponv a suitable frame or stand 20. The type of Y dispenser chosen for illustration is the Olla type, made of unglazed pottery. When afilled bottle of water Yis v seated in the dispenser ()as shown, water passes from the bottle into the dispenser until the surface 21 of the watervin the dispenser rises to seal,
the open end of the bottle, thereby preventing further passage of water from the bottle to the dispenser. As water is drawn ofi' from thedispenser through its faucet 22, the surface 21 of thel water` in the vdispenser is loweredv from Contact with the bottle, and air VV from the space 23 in the dispenser above the `Water enters the'bottle andfbubbles through the water in the bottle to the space 24 at the top of theV inverted bottle. The purpose of space 23 as required for the above described action. e
The cushion C may be of anycontinuous configuration to conform with the shape of the dispenser and bottle, preferably circular. My preferred form consists of a ring portion edge thereof. The cushion is suitably dimen- 4si'oned tofseatsnuglyin the top rim of the Y `dispenser D, and is shaped to embrace the inverted bottle lrmaling in both 'casesjsub A.
stantially air-tight contact.
A vent passage 27, preferably rectangular Y in cross-section, opens inwardly at the bottom of ring portion 25 to communicate with space 23 within the dispenser D. It extends upward through the ring-portionv25, outwardV throughr annular'flange 26, andv terminally turns downwardly to communicate with the f atmospln-ne at thejunder surface of flange 26. Preferably, a portion of the annular flange 26Vextends radially outward'intlie form of an 'overhanging lip 28". The' purpose of this lip is to vforma body through which the vent aperturer27 may be extended radially from the ring portion 'and by which ythe exterior end of the passage may be effectively shielded from above.V The lip also serves to rdesirably `extend the length of the vent pas`` sade.
Passage 27, preferably near its-outerend,
is normally sealed by a valve V which automatically opens to admit the passage ofair to space23 as required'. Preferably thisvalve is a lflap valve that is opened by external pressure and, as shown in Figs. 4.and5, may be made integral with the cushion. For this purpose l terminate vent passage 27 in a T-shaped opening in lip 28, the head 29 ofmay bepivotally turned or folded inwardly.
Integral with plug-32 is 'an extended Hap e 32a. Plug 32 is so dimensioned that when f folded inwardly, as shown in Fig. 5, it is snugly received and retained by the head portion 29 ofthe T-shaped opening. When the plug is soV ositioned abuttingthe louterl ends of e shoul ers 31, flapv 32a overlies shoulders 31 and extends inwardlyto entirely Vseal the stem portion* 30 of the T-sha-ped opening.' The iap 32a may be `lifted by ya slight preponderance of external pressure. It is evident that the valve .may be cheaply manufacturedy andV quickly assembled to its operative position.
The operation of my invention may be understood from 4the foregoing description. f When water level 21,drops from contact with the bottle', it is restored by water 'passing space 23 passesinto the bottle vto compensate for the loss of water. jWhen air in'space 23 is sufliciently reduced in pressure'by such action, atmospheric pressure opens fiap valve V to admit additional air.
A modified form C of my cushion Figs. 7 to 10, inclusivleis substantially idenshown in' -fromthe bottle to the dispenser and'air from iso l vtical to the preferred form shownl above, ex-V cept in the construction ofthe valve V. All other parts have corresponding numerals.
In this form, passage 27 terminates outwardly in a downwardly presented and preferably rectangular opening 35, theV innerl edge of which is defined by a shoulder 86. This rectangular opening is spanned by two coacting valve lips 37, contiguous edges of which mutually impinge to normally seal off the opening. Lips 37 have an inherent tendency to maintain the seal as shown in Fig. 9,
' but are suitably shaped to be sensitive to external pressure, responding by collapsing inwardly j and momentarily separating, as shown in Fig. l0. Preferably the lips are integral with the cushion, one springing from shoulder 36 and the otherl from the overhanging end 33 of lip 28', but the valve may be formed in a separate rectangular plug designed to be cemented into opening 35. In either case, it is preferred that'the lips be permanently sealed along their lateral edges to the sides of rectangular opening 35. Actuated by external atmospheric pressure the valve V serves the same purpose as valve V inthe preferred form. One advantage of the modified form is that the two lips, when momentarily collapsed inwardly as indicated in Fig. 10, tend, because of their inherent elasticity, to return to the normal position indicated in Fig. 9 with a quick, positive movement. This outward Hip tends to keep the lips free from dust andV effectively dis-` tially air-tight joint between an inverted bottle and a water dispenser, comprising: a
continuous rubber member having a lateral .passage yextending therethrough; and a pressure-actuated valve normally sealing said passage. n
3. A cushion adapted to form a substantially air-tight joint betweenvan inverted bottle and a water dispenser, comprising: a
continuous rubber member having a lateral passage extending therethrough, said passage being downwardly disposed at its outer end; and a valve normally sealing saidpassage.
4. A cushion adapted to form a substan tiallyVair-tight seat for an'inverted water bottle in awater dispenser, comprising: a
rubber member having a ring portion formed with an integral annular flange at the upper edge thereof, said member having a passagev f di therethrough extending from the bottomof the Vring portion-through the annular flange;
and av valve within said passage normally.
sealing the outer end of said passage and adapted to be opened by externalpressure. 5. A cushion adaptedl to form a substanbottle in a water dispenser, comprising: a rubber member having a ring portion formed with an integral yannular flange at the upper edge thereof, said member havinga passage'. therethrough extending from the bottom of the ring portion through the annular flange, the outer end of the passage being disposed downwardly; and a valve within said passage.
