the bottle until the cap seals against the stationary member flange 37 however the float 51 is made sufficiently rigid so as to impress sufficient sealing load on the upper plug 59 to seal against the stationary member 39 s upper seat 48 regardless of bottle attitude be it upright upsidedown or in any other position fig4 depicts a second embodiment of dispensing device 27 39 in cross section this configuration will also limit interflow by providing a 34 pop 34 action to the valve in its upward transit a stationary member 36 39 of this embodiment is much the same as that of the first embodiment regarding its fitting and sealing within a lower bottleneck 35 39 it also possesses a supporting bulkhead 43 39 leading inwardly to a hollow reservoir portion 44 39 the upper portion of the said reservoir being formed by an upward cylindrical extension 45 39 of the said bulkhead the lower portion of the reservoir is also formed by a separate tightly fitting and sealing lower seat portion 46 39 however the stationary member 36 39 of this embodiment possesses a second upward extension 64 which may be snap fitted or otherwise mechanically retained to the top of the first cylindrical extension 45 39 by for example snapping over an annular lobe portion 65 of the first extension 45 39 this second cylindrical extension 64 tapers upwardly and inwardly to a fixed restriction inlet 66 below said inlet 66 a hollow chamber 67 is formed leading to an inwardly tapering conical upper seat 48 39 the innermost.
