Improvements in and connected with Bottle Stoppers.
I, LOUIS ADOLPHUS EBERHARDT, of 227 Pearl Street, New York, County
and State of New York, United States of America, Chemist, 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 a bottle stopper which permits a free discharge from
the bottle, but prevents re-filling. Thus spurious replenishing of genuine bottles
is avoided.
In the accompanying drawing:
Fig. 1 is a side view of a bottle provided with my improvement.
Fig. 2 is a longitudinal section through the bottle neck.
Figs. 3, 4 and 5 are cross sections of Fig. 2 on the lines, x, y, y, I, I,
respectively.
The letter A, represents a bottle, within the neck of which there is secured a
plug d, preferably made of glass. This plug is somewhat narrower than the bore
of the neck, and is secured in place, on top by a cement or similar packing a,
and at the bottom by an annular soft rubber cap b, that engages a head d', of the
plug and is received by a groove A¹, in the bottle neck. Between the cap b, and
the plug is interposed an annular hard rubber disk c. The plug d, is provided in
its lower part with a valve chamber d², open at the bottom and containing a
suitable valve e. From the chamber d, horizontal ports d³, lead to the annular
space between the plug and the bottle neck. The upper part of the plug is con-
nected to the lower part by a set of legs a. This upper part is provided with a
central upright perforation d³.
When the bottle is tilted to pour out the liquid, the valve e, will be thrown off
its seat c, and the liquid will flow into valve chamber d, thence out of ports d³,
between the legs d', and out of opening d³.
As the valve e, closes the opening in the lower part of the valve chamber, when
the bottle is in an upright position, it is evident that liquid cannot be filled into
the bottle. Nor can the valve be raised by a hooked implement because the
openings d³, d, are out of line.
I prefer to surround the bottle by a suitable band or label, that becomes partly
destroyed or injured when subjected to the action of the liquid for which the bottle
is used. This prevents the bottle from becoming surreptitiously filled by being
placed horizontally within a bath.
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. The combination of a bottle with a plug having a valve chamber d², laterally
extending ports entering the same and a valve within the chamber, substantially as
specified.
2. The combination of a bottle with a plug having a valve chamber d², laterally
extending ports entering the same, legs d, and an upright perforation do, substan-
tially as specified.
3. The combination of a bottle with a plug having valve chamber d², laterally
extending ports d³, and with a valve e, an annular disk c, and a cap b, substantially
as specified.

page_text: 4. The combination of a bottle with a plug that prevents re-filling and with a
destructible label surrounding the bottle, substantially as specified.
