Improvements in Stoppers for Bottles, Jars, and like Vessels for
Containing Liquids.
We, JOSEPH DURAND of No. 17 Rue du Ruisseau Paris, in the Republic of
France, Clerk, and FREDERICK GRAEF-BEAUMONT of No. 203 Rue Lafayette,
Paris, in the Republic of France, Civil Engineer, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :—
The subject of the present invention is a safety stopper for all classes of bottles,
jars and like vessels for containing liquids, and notably for bottles containing
beverages or other liquids of which it is desired to prevent the adulteration. This
system of stoppering allows of the liquid contained in the bottle, or other vessel,
being poured out, but it renders the introduction of any other matter, liquid or
solid, impossible.
The accompanying drawing represents our system of safety stoppering or safety
stoppers.
Figure 1 represents a vertical section of the stopper ;
Figure 2 represents a transverse section on -y.
Figure 3 represents a vertical section of a modified stopper, and
Figure 4 gives a transverse section of it on u-r.
Figure 5 is an elevation of the tapering plug.e.
Figures 6 and 7 are a plan and elevation respectively of the valve or plug c.
Figure 8 is a plan of the float or diaphragm b.
This
The stopper properly so-called A is hollow and consists of two halves a the
vertical joint of which is soldered or joined in some suitable manner.
stopper A is of any suitable material, preferably of glass, and its lower part a¹ can
be soldered into the neck of the bottle after the introduction of the liquid, in such a
way that the bottle and the stopper form one single piece.
The orifice a³ which establishes the communication between the interior of the
bottle and the hollow interior a² of the stopper A is closed by an elastic float or
diaphragm b, preferably, of india-rubber; this float covers the bottom of the
hollow a. On this float b, there is placed a flat glass valve or plug c of
substantially cylindrical shape actuated by the spring d; a tapering plug e, shaped
like a spigot, closes the exterior orifice a* of the stopper.
The action of the new system of stoppering is as follows:-
In order to pour out the liquid, contained in a bottle, jar or other vessel fitted
with this safety stopper, the plug e is first removed. On inclining the bottle the
spring d is compressed by the weight of the liquid bearing down upon the valve and
diaphragm c, b, which opens under this pressure and allows the liquid to flow out at
the orifices a³, a², a*.
On raising the bottle up again, the spring d again exerts its action upon the
valve and diaphragm c, b, which immediately hermetically closes the orifice a³, thus
preventing the introduction of any other liquid. The bottle when quite empty is,
therefore, useless.
The valve c, being of glass, it is quite impossible to pull it upwards by means of
a cork screw or any other similar appliance, and this gives a further guarantee for
the impossibility of refilling the bottle.
Should any special circumstances render it necessary to pour out the liquid more

page_text: quickly than is possible by this means, arrangements can be made to admit air into
the stopper. Such an arrangement is shown in Figures 3 and 4.
A small glass tube, starting from the bottom of the bottle, traverses the lower
part of the stopper A, passes by the valve c and through it and communicates with
the exterior air by means of the hollow interior a² of the stopper A, and by means
of the small orifice g in the stopper A. The special arrangement of the tube f, and
of the orifice g, represented in Figure 3, prevents the introduction of any liquid,
but allows the air to enter the bottle whilst the liquid therein contained is being
poured out.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A stopper for closing bottles, jars, and like vessels, characterised by a hollow
stopper enclosing au elastic float or diaphragm upon which presses a hard
cylindrical valve held in position by a spring constructed substantially as herein
described and set forth.
2. In combination with a stopper for closing bottles, jars, and like vesse's,
characterised by a hollow stopper enclosing an elastic float or diaphragm upon
which presses a bard cylindrical valve held in position by a spring, of a side tube
or vent adapted to admit air to the contents of the bottle, constructed and operating
as and for the purposes herein described and set forth.
