Improvements in and connected with Drop Bottles or Glasses for
Medicines and other Preparations.
A communication by HERMANN LAMPRECHT, of the Glass Works, Marienhütte,

I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to glasses for pouring by drops, the stopper of which is
fitted in tightly and so made that with the assistance of the passages or channels
made in the neck of the bottle, by a quarter turn it allows the air to enter the
bottle and the liquid contained in the same to flow out drop by drop.
This invention has for its object, to form such a bottle so that only pure air freed
same; the
from all deleterious germs may penetrate into the interior of the
advantage hereby obtained, that is to say the security against infection obtained by
means of this new invention, is of great importance, more particularly for such
bottles as contain injection liquids such as Koch's lymph and the like, and from
which some of the contents are to be removed, whilst the bottle is in an air charged
with the deleterious germs. In front of the opening of the usual dropping bottles,
a glass ball is arranged and this latter is filled with wadding or other like material, and
all the air which passes into the bottle through an opening in the glass ball must
pass through this material leaving there all micro-organisms. It preferable to
form this chamber which contains the wadding or the like in the stopper of the
bottle.
The ordinary conical ground stopper is provided at the bottom with a channel
which extends to about half its length. The whole stopper is hollow, and has
above an opening in its knob which is preferably shaped as a hollow ball, and
below another opening. The whole stopper or merely the upper part is filled with
antiseptic substances or with wadding, moss, felt or the like. The neck of the
bottle has a channel forming an extension of the spout, which extends downwards
somewhat below the upper end of the stopper channel.
Opposite to this channel a second one is arranged commencing at the opening in
the stopper, and this second channel communicates with the interior of the bottle.
It is evident without further explanation that liquid can only be removed from
the bottle or air penetrate therein, when the stopper is turned into a certain
position, the liquid then flows through the passage of the stopper and its continua-
tion the channel of the bottle.
The air on the other hand streaming in to an equal extent enters at the upper
opening of the stopper into the stopper, passes through the substances contained
therein, is entirely purified from the germs contained in it, passes out through the
lower opening of the stopper and flows through the lower channel in the neck of
the bottle into the interior of the bottle.
A second opening may be made opposite the first one, in order to allow of
the substances contained in the stopper being easily changed; the knob of the
stopper may be made of circular, oval or other suitable form, the opening may be
made at the side, top or bottom.

Improvements in and conneoted with Drop Bottles or Glasses for
Medicines and other Preparations.
A communication by HERMANN LAMPRECHT, of the Glass Works, Marienhütte,
near Gnarrenburg, in the Empire of Germany, Manufacturer..
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6. Bank Street,
Manchester, both in the County of Lancaster, and 323 High Holborn in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this inven-
tion 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 glasses for pouring by drops, the stopper of which is
fitted in tightly and so made that with the assistance of the passages or channels
made in the neck of the bottle, by a quarter turn it allows the air to enter the
bottle and the liquid contained in the same to flow out drop by drop.
This invention has for its object, to form such a bottle so that only pure air freed
from all deleterious germs may penetrate into the interior of the same; the
advantage hereby obtained, that is to say the security against infection obtained
by means of this new invention, is of great importance, more particularly for such
bottles as contain injection liquids such as Koch's lymph and the like, and from
which some of the contents are to be removed, whilst the bottle is in an air charged
with the deleterious germs.
On the accompanying drawings:
Figure 1 shows one of the usual drop bottles with inserted stopper, in front of
the opening d however of which a glass ball S is arranged and this latter is filled
with wadding or other like material, and all the air which passes into the bottle
through an opening e in the glass ball must pass through this material leaving there
all micro-organisms. It is preferable to form this chamber which contains the
wadding or the like in the stopper of the bottle, this form of construction is shown
in Figure 2. F represents the bottle and S the stopper.
The ordinary conical ground stopper is provided at the bottom with a channel a
which extends to about half its length. The entire stopper is hollow, and has
above an opening e in its knob which is preferably shaped as a hollow ball, and below
another opening d. All the stopper or merely its upper part is filled with antiseptic
substances or with wadding, moss, felt or the like. The neck of the bottle has a
channel or passage b forming an extension of the spout, which extends downwards
somewhat below the upper end of the stopper channel a.
Opposite to this channel b a second one c is arranged commencing at the
opening in the stopper, and this second channel c communicates with the interior
of the bottle.
It is evident without further explanation that liquid can only be removed from
the bottle or air penetrate therein, when the stopper is turned into the position
shown in the figures, the liquid then flows through the passage a of the stopper and
its continuation the channel or passage of the bottle.
The air on the other hand streaming into an equal extent enters at the upper
opening e of the stopper into the stopper, passes through the substances contained
therein, is entirely purified from the germs contained in it, passes out through the
lower opening d of the stopper and flows through the lower channel c in the neck of
the bottle into the interior of the bottle.
A second opening may be made opposite the first one e, in order to allow of the
substances contained in the stopper being more easily changed; the knob of the
stopper may be made of circular, oval or other suitable form, the opening e may be
made at the side, top or bottom.

page_text: Figure 3 on the accompanying drawing is a section on the line a¹-x² of Figure 1,
whilst
Figures 4 and are sections on the lines x-x, y-y, respectively of Figure 2.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, 1 declare that what I claim is;
1. A drop bottle or glass in which the liquid contained in the same is kept
aseptic, by the outside air which penetrates into the bottle in order to cause the
liquid to run out in drops, being forced to pass through a chamber filled with
wadding or other material arranged in front of the air inlet.
2. A drop bottle or glass of the kind described in Claim 1 the stopper of which
is hollow and is so formed that when the bottle is used the air which penetrates by
the opening e passes through the chamber of the stopper, and only after doing so
can reach the interior of the bottle by escaping through the lower opening d by
means of the channel c in the neck, the stopper which is filled with wadding or
other suitable material serving as a filter for the inflowing air.
