COMPLETE SPECIFICATION.
Improved Method of Stoppering and Filling Bottles used for Volatile
Liquids.
I, HEINRICH GOETZ, Merchant, of 17, Schleusenstrasse, Frankfort a/Main, in
the Empire of Germany, 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 new method of stoppering and filling bottles
used for volatile liquids, employed in medicine and in industrial operations,
more particularly ethyl chloride and methyl chloride.
Figs. 1 and 2 illustrate the stoppering arrangement in elevation and in
section.
Fig. 2 shows in detail, the several parts of which the same is composed.
Figs. 3 and 4 are clevations of bottles with slightly modified forms of stoppers,
Fig. 5 shows a bottle opened for use, and
Fig. 6 a sectional elevation of filling apparatus.
Into the neck of the bottle which is preferably of cast glass and emery
ground in the form of a cone, a metallic body consisting of two parts a and b
is inserted instead of the ordinary emery ground glass stopper: the part has
two conical surfaces, the lower one being fitted as perfectly as possible into the
cone shape neck. The joint is filled in with any suitable adhesive substance,
the space between the upper cone and the neck of the bottle being also filled
in with some kind of impermeable cement, Figs. 1 and 2.
The two parts a and b shown in section in Fig. 2 are bored through the
part being internally screw-threaded to receive the screw-threaded lower end
of the part a which is employed for pouring out the volatile liquids, a is
furnished with a glass stem f in which is a capillary orifice, and at the bottom,
by which it is connected with the piece b, presses against a leaden ringe. The
capillary orifice is closed by a screw cover g, which is made tight by pressing
against an india-rubber ring placed in the groove h of the piece a.
of an india-rubber ring a leaden one may be employed, in that case the cover g
is furnished with a bar i, which acts as a lever, see Fig. 2ª.
Instead
If it be desired to avoid the loss of time occasioned by the necessity of screw-
ing and unscrewing of the cover 9 this cover is dispensed with the capillary
orifice being hermetically closed by a cap k furnished in the interior with an
india-rubber washer and forming one arm of a lever pivotted in a lug fixed
either to the stopper or to a ferrule m, surrounding the neck of the bottle.
The cap or cover k is pressed against the orifice under the influence of a spring
which acts on the other arm of the lever. The spring is composed of a small
steel plate applied to the edge of a metal plate y attached to the ferrule m,
Fig. 3, or by a U shape metal plate, Figs. 4 and 5, or in any other manner.
this case the ring with the groove h on the piece a is despensed with.
In
The bottle is opened by pressing down the end of the lever arm 1, see Fig. 5.
A slight pressure of the thumb on the cap k brings it back to its former position
and closes the bottle again.

page_text: The orifice n for filling the bottle can be made at the top, see Figs. 3 and 4, or
at the bottom of the same, see Fig. 5.
The apparatus for filling the bottle is shown in Fig. 6. It consists of a cock p
the nozzle of which is turned upwards and is furnished with internal and
external screw threads To the outside a case s is screwed, and in the inside a
small tube t, the top of which extends beyond the case s.
When the bottle is
screwed on to the cock of the vessel o from which it is to be filled, the tube t
forms an abutment in coming into contact with the valve u (placed in the
orifice and closing the same under the pressure of a spiral spring ), pushes
it back and renders it possible for the liquid to enter the bottle. The pressure
If the bottle be un-
screw regulates the quantity drawn from the vessel o.
screwed from the cock, the valve closes automatically in consequence of the
pressure of the spring v.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In a new method of stoppering and filling bottles used for volatile liquids,
a metallic body consisting of two parts a and b, the latter having two conical
surfaces, the lower of which is exactly fitted to the interior of the neck of the
bottle and held by means of a suitable adhesive substance, the space c between
the upper cone and the neck of the bottle being filled in with an impermeable
cement, substantially as described with reference to Figs. 1, 2 and 2.
2. In a new method of stoppering and filling bottles used for volatile liquids,
a cap forming one arm of a lever, mounted on the stopper and actuated by
the spring a substantially as described with reference to Figs. 3, 4 and 5.
3. In a new method of stoppering and filling bottles used for volatile liquids,
the filling means comprising the filling orifice, the valve u forced against the
orifice to close it by the spiral spring v. and forced away to open the orifice by
the tube in the orifice of the cock p employed in connection with the vessel
used for filling the bottles, and which tube forms an abutment at the moment
when the bottle is screwed on to the above-mentioned cock and renders it possible
for the liquid to enter the bottle.
