Improvements relating to the Stopping of Bottles and Vessels to
contain Liquids.
•
I VICTOR CHARLES MONETTE, Pharmaceutical Chemist, of 23 Boulevard de
Strasbourg, Paris, in the Republic of France do hereby declare the nature of this
invention to be as follows:-
The object of this invention is to permit of the contents flowing out drop by drop,
and also to prevent the withdrawal of the stopper for the purpose of fraudulently
re-filling the vessel.
In carrying out the invention, the plug of the stopper is partially covered with
cork, and the stopper is pierced with a hole in the line of its axis for the escape of
the liquid. This hole is closed by a plate pivotted in a recess of the stopper, and
provided with a serrated outer edge to serve as a hold for the finger of the
operator, and a perforation to form a continuation of the hole under certain
conditions.
The plug is hollow, and receives in its interior an inverted cone, which, when
pushed down by a rod, will force out pins arranged in holes formed in the side of
the stopper.
These pins enter a groove formed inside the neck of the vessel, and the stopper
is thereby locked in the vessel.

COMPLETE SPECIFICATION.
Improvements relating to the Stopping of Bottles and Vessels to
contain Liquids.
I VICTOR CHARLES MONETTE, Pharmaceutical Chemist, of 23, Boulevard de
Strasbourg, 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 relates chiefly to that class of bottle stoppers which permit the
liquid contained in the bottle to be drawn only drop by drop, and has for its object
to render it impossible to draw the stopper from the neck of the bottle or other
vessel to which it may be applied, for the purpose of fraudulently refilling the
vessel.
The improvement, which may be applied with advantage to the device for
measuring out liquids for which I obtained Letters Patent dated January 10th 1890,
No. 478, is applicable to all forms of bottles or vessels.
In the accompanying drawing :-
Fig. 1 is a transverse vertical section of a stopper constructed according to my
invention, ready for insertion into the neck of a bottle.
Figs. 2 and 3 are horizontal sections of the same, taken respectively on the
lines M N and P Q.
Fig. 4 is a transverse vertical section of the stopper in place in the neck of a
bottle.
Figs. 5 and 6 are horizontal sections of the same, taken respectively on the
lines M' N and P'Q¹.

page_text: A is a metal stopper furnished with cork a, and pierced with a hole 6 for the
passage of the liquid contained in the bottle. c is a conical thimble fitted within
the stopper, and pierced with holes d d. e e are pegs arranged radially around the
stopper, four being shown in the drawing,-but any desired number may be
employed.
As shown in the drawing, the arrangement is applied to a drop-counting bottle,
which, as will be seen, is provided at the top with an obturator f, formed of a plate
of metal pivotted at g, and having a roughened or serrated edge at h, which-serves as
a hold for the finger in uncovering the orifice b. Besides this, the obturator is
fitted with a small piece of cork i, pierced with a small hole j
The neck of a bottle filled with liquid, into which the drop counting stopper
thus formed is introduced, is furnished internally with an annular groove y, opposite
the pegs ee, when the stopper is in position.
The obturator is now turned to the open position, with the orifices and ¿ in line;
a rod is then thrust through the opening, driving the thimble downwards, and
thereby pushing out the pegs ee into the annular groove y inside the neck of the
bottle.
It will now be understood that in order to use the bottle, it is only necessary to
turn the obturator to the open position shewn in Figs. 4 and 5, when the contents
the bottle can be poured out, the holes d at the bottom of the thimble & permitting
of the flow of the liquid.
C
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 :-
A stopper for bottles consisting of an outer case and an inner conical thimble,
and a set of radially-projecting-pegs-engaging with the bottle neck, all arranged and
operating substantially as shewn and described, for the purpose set forth.
