The valve member is rotated in its seat 3a by means

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.
' 2. Device as claimed in claim 1, wherein the diam
eters of the larger base of the valve head portion and tu
bular extension are substantially the same.
3. Device as claimed in claim 1, wherein the free end
of the stern of the valve member is of ragged pro?le pre
venting sticking thereof to a disc fast with the tubular
extension of the valve body.
4. 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
