Improvements relating to the Manufacture of Aërated Liquids and
to Bottle-stoppers and other Apparatus for Facilitating such
Manufacture.
I, ADOLF KNOOP, of 16, Marienstr; Minden, Westphalia, Germany, Manufacturer
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 relates to the manufacture of aërated liquids, and to bottle-stoppers
and other apparatus for facilitating such manufacture.
In order to bottle mineral water and other aërated liquids, the bottles, according to
the method which forms part of the said invention, are first filled with the liquid to
be impregnated with carbonic acid. When the bottles have been filled, they are
placed in a drum or other receptacle, the latter is then closed gas-tight, and the
carbonic acid is introduced. To enable the carbonic acid to enter into the liquid, the
bottles are provided with stoppers which allow the acid to enter the bottles but not
to pass out. These stoppers are formed with a hole or bore, one orifice of which is
outside the bottle and is free or uncovered, whilst the other orifice is inside and is
normally kept closed by an elastic band, or a flap or other valve.
In the accompanying drawing are represented some forms of bottle-stoppers and
an apparatus for facilitating the aëration of liquids contained in bottles which are
provided with such stoppers.
Figures 1, 3, 5, 7, and 9 are sections of stoppers seated in the neck of the
bottles.
Figures 2, 4, 6, 8, and 10 are views from below of the said stoppers.
Figure 11 is a section of the aërating apparatus.
The lower part of the stopper shown in Figure 1 is provided with an annular
groove a, and the core 6 formed thereby is surrounded by an india-rubber ring.
Through the stopper extends a hole or bore d the upper orifice of which is free
or uncovered and the lower orifice is normally kept closed by the india-rubber ring c.
The lower part of the stopper represented in Figure 3 is made somewhat thinner than
the other part of the same and is surrounded by an india-rubber ring c which covers
the orifice of the passage d.
The stopper represented in Figure 5 is provided below with a circular india-
rubber disc e forced laterally between a protruding lug e¹ and the end of the stopper,
thus closing the lower orifice of the passage d.
In the arrangement shown in Figure 7, the lower part of the stopper is provided
with an annular groove f in which the interior edge of an india-rubber disc formed.
.

ordinarily kept closed by the said india-rubber disc g.
In the modification represented in Figure 9, the hole or passage d is controlled by
means of a valve h.
Instead of providing the stoppers with screw-threads as represented in some figures
of the drawing, the parts of the same which are inserted into the bottle-neck can
be made smooth, the only essential feature being that they are provided with a hole
or passage d and the described means for closing or controlling the latter.
The necessary quantity of liquid having, been introduced into the bottles, these are
closed by my improved stoppers, and then placed in a drum or other receptacle i such
as that illustrated in Figure 11, the man-hole in the said drum or receptacle being
closed in the known manner by means of the cover k and a bridge 7 so as to form a
l
gas-tight and water-tight joint. The said drum or receptacle is supported by journals
in two standards and is adapted to be rotated, for which purpose one of the journals
extends beyond its standard and is provided with pulleys n or a crank, according
as the drum is to be actuated by mechanical means or by hand. The journal on the
other side of the drum or receptacle has a central passage or bore with which a pipe
for conducting carbonic acid into the said receptacle is in communication.
If carbonic acid is introduced into the drum or receptacle it passes to the bottles
and through the holes or passages d in the stoppers into their interior, the
aforesaid means or devices for keeping the said holes or passages normally closed
being opened by the pressure of the carbonic acid, and the impregnation of the
liquid takes place.
By turning or rocking the drum or receptacle i, the carbonic acid becomes in-
timately mixed with the liquid contained in the bottles. After some time the
admission of carbonic acid is stopped and the receptacle is opened. At this moment,
owing to the sudden decrease in the pressure from the outside the india-rubber
rings, discs, or other means for controlling the holes or passages in the stoppers
will close the latter and remain permanently closed. Before, however, opening the.
drum or receptacle, the carbonic acid which has remained in it unused is caused to
return to the holder or reservoir whence it was obtained, so that no loss of carbonic
acid takes place.
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 -
First. For closing bottles filled with aërated liquids, the employment of stoppers
having a hole or bore d which is kept closed by an elastic disc or ring inside of the
bottle, substantially as, and for the purpose, hereinbefore described with reference to
Figures 1 to 10.
Second. An apparatus for aërating liquids in bottles, provided with stoppers such
as are hereinbefore described, consisting of a drum or receptacle i having a man-
hole, an admission passage for carbonic acid, and devices for enabling the drum or
receptacle to be rotated or rocked.
Third. A method of preparing aërated beverages in bottles, which consists in filling
bottles with the liquid to be impregnated, closing the said bottles by stoppers such as
are hereinbefore described, placing them in a drum or receptacle adapted to be closed
gas-tight, to admit carbonic acid, and to be rocked or rotated.
