Unauthorized re-?lling of the bottle is prevented in The sharp-edged circumferential lip 9 on the valve 70 any position including the horizontal position of the bot body 5 and the circumferential portion of the disc 12 cf tle through thrust exerted on the valve member 14 by a aoagsaa 3 liquid tending to ?ll the bottle.

It will be seen from FIGURE 4 that A; The valve member is rotated in its seat 3a by means of the cover 19 and its stem 20. The frusto-conical head 16 is formed on its larger circumference with a tooth 31 projecting radially and outwardly. The tooth 311 is of the thrust of liquid on the inner surface of an annular recess 25 between the valve head portion 16 and stem 15 such a length that on rotation of the valve member 14 in its seat 3a the tooth abuts the inner edge of the near est rib it} (FIGURE 8). presses the valve member 14- against the seat 351.

This is su?'icient to break the seal Even in the limit case shown in FIGURE 3, in which the valve is at its maximum lift and abuts in a centered position the tubular extension 11, the liquid friction on the outer wall on the head portion 16 is' sut?cient to slightly remove the valve from the said. position, where' pon the valve falls back closing the seat 3a. To prevent the valve 14 from being stuck-up to the disc I12 by sugary or similar deposits, the tubular stem 15 is provided at its free end with a ragged edge 17. FIGURES 6 to 8 show a modi?ed valve construction. Parts common to the previously described embodiment are provided with the same reference numerals. The washer 3 is formed on its top surface with an annular ex tension 28 which becomes engaged on ?tting of the valve body 5 to the washer by a plurality of notches cut in the base of the ribs 10'. The extension 28 is formed with an annular groove 29 adapted to receive by snap action a matching rib 29a on the inner wall of the bottom sleeve portion 6 of the valve body 5. The head portion '16 on the valve member 14 is made frusto-conical. The end Bil on the stem 29 on the cover 19 is of cruci form cross section and is adapted to engage a comple mentary seat 21 in the tubular stem 15 on the valve mem ber 14 on pressing of the latter onto its seat 3a. The cover 19‘ can be depressed to cause its bottom flange 22 to bear on the ?ange '7 on the valve body 5. The length of the stem 20 is such as to press in this posi tion the valve member 14 onto its seat 3a, thereby afford ing a tight seal through the slight resilient deformation of the latter. In this position of the cover 19, or if the latter is slight ly lifted from the valve body 5, provided the stem end 30 is still engaged by the seat 21, the stem 15 on the valve member 14 remains coupled with the cover 19, which obviates a de?ciency which might arise in thefem and equalize the pressure within and without the bottle. Upon upsetting of the valve member ‘.14, the closure operates like the embodiment described with reference to FIGURES 1 to 5. What I claim is: l. Valved bottle ‘closure adapted'to prevent unauthor ized re-?lling, comprising a valve body and a valve seat both ?xed to the bottle neck and a mushroom valve mem ber comprising a cylindrical stem and a hollow head por tion the outer surface of which is a revolution surface adapted to engage sealingly the valve seat, the said valve member being movable within a valve body and guided therein by guide means comprising an inner tubular ex tension of the valve body having a substantially larger diameter than said cylindrical stem and a plurality of ribs extending radially and inwardly from said valve body to de?ne a cavity having a substantially larger diameter than said valve head portion.

Device as claimed in claim 1, wherein the head on the valve member is formed with an axial recess facing, the bottle inside which, on leaning of the bottle, becomes ?lled with liquid, thereby facilitating unseating of the valve member from its seat. 5. Device as claimed in claim 1, wherein the free end of the stem on the valve member is formed with a pris matic seat, a cover being provided comprising a stem, the free end of which is engageable by the said seat to couple in rotation the cover‘ and valve, the head on the valve member being provided with a radial tooth adapted to abut on rotation of the valve in its seat radial ribs on bodiment shown in FIGURES 1 to 5. the valve body to unseat the valve member from its seat.
