Improvements in Stoppering Bottles, Flasks, and other Receptacles
for Containing Liquids and similar Materials.
I, HENRI CHOSSEFOIN, Chemist, of No. 31 Rue Duret, Paris, in the Republic
of France, 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 :-
This invention consists in a form of stopper for bottles, flasks and other
receptacles, with the object of protecting the liquids or similar materials which
are contained therein from being replaced, altered or mixed.
For this purpose the stopper in question is so formed that the liquid originally
contained in the flask may be easily withdrawn, but that it then becomes
impossible to introduce new liquid.
The stopper in question is constructed in the manner hereinafter described with
reference to the accompanying drawing, in which :-
.
Fig. 1 shows a bottle or flask A constructed for effecting the desired object.
Fig. 2 shows the tube C which is placed in the neck or mouth of such flask.
Fig. 3 shows the movable stopper B.
Fig. 4 shows the bottle closed or stopped after the liquid has been introduced.
The bottle A shown in Fig. 1, which is generally made of glass, is constructed
so as to suit the object in view, and has its neck divided into two portions, the
upper part being rather bigger than the lower part, so that such neck has an
inwardly projecting shoulder at the point indicated by the line 1-2.
neck is further drawn in or narrowed towards its base so as to form a kind of
funnel.
Such
In the lower part of the neck after the bottle has been filled with any desired
liquid or similar material, a part B, called the "movable stopper" (shown in
Fig. 3) is introduced, the base of such stopper being in the form of an elongated
cone, and having at the iniddle of its height a circular recess, and in its upper
part vertical alternating grooves and projections, with a hollow in the centre.
Above this stopper a glass tube C (shown in Fig. 2) is introduced into the
upper part of the neck of the bottle, where it fits with a frictional contact and
is cemented or otherwise stuck to the neck, the inner wall of such tube being
conical towards the bottom, so that its lower orifice is much narrower than the
upper opening. The insertion of this glass tube into the neck is regulated or
limited by the inwardly projecting shoulder at the point 1-2.
A cork is then used to close the bottle in the ordinary manner, and the bottle
thus fitted presents the appearance shown in Fig. 4.
In this condition, the liquid or other contents may be readily poured out of
the bottle or flask, by simply tilting same when uncorked. The movable
stopper B being forced by the liquid or other material towards the top of the
flask abuts against the base of tube C, which limits its movement, and the liquid
or other material then passing round the base of such movable stopper and
through its vertical grooves ruus through the tube C to the outside of the flask.
When once the liquid or other similar material has been poured out it becomes
impossible to introduce a new liquid or similar material into the same flask, bottle,
or other receptacle. The movable stopper B in combination with the tube C
prevents this.
The respective arrangement of these two accessory fittings of the flask or other
receptacle is calculated so that it will be impossible either to remove or to raise

page_text: the said movable stopper B with the object of facilitating the introduction of a
new liquid or similar material.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In a bottle, flask or other receptacle made of glass, porcelain, or other analogous
or suitable material:-
--
1. The special construction of the neck or mouth of such receptacles comprising
the narrowing in the form of a funnel towards its base and an inwardly projecting
shoulder towards the middle;
2. A movable stopper of glass, porcelain, or other analogous or suitable material
which is hollowed out and grooved, and which is placed in the lower part of the
neck or mouth, in which it is capable of vertical movement;
3. A glass tube having its internal wall or surface conical towards the base,
and which is forced into and secured in the upper part of the neck or mouth,
the inwardly projecting shoulder of the neck or mouth limiting the extent of the
insertion;
The whole substantially as described and shown and for the purpose specified..
Dated this 4th day of December 1893.
