Year: 1873

page_text: LETTERS PATENT to Paul Hubert, the younger, and Volcy Boissel,
both of Bordeaux, in the Republic of France, for the Invention of
"AN IMPROVED METHOD OF STOPPERING FLASKS, BOTTLES, AND OTHER
VESSELS."
Sealed the 2nd June 1874, and dated the 5th December 1878.
PROVISIONAL SPECIFICATION left by the said Paul Hubert and Volcy
Boissel at the Office of the Commissioners of Patents, with their
Petition, on the 5th December 1878.
We, PAUL HUBERT, the younger, and VOLOY BOISSEL, both of
Bordeaux, in the Republic of France, do hereby declare the nature of
the said Invention for " AN IMPROVED METHOD OF STOPPERING FLASKS, BOTTLES,
AND OTHER VESSELS," to be as follows, that is to say :—
This Invention consists in an improved method of stoppering flasks,
bottles, jars, and other vessels in a simple and effective manner, whereby
an air-tight closing is obtained, such stoppering also serving as a capsule.
To carry out our Invention we fix on the exterior of the neck of the
flask, bottle, jar, or other vessel, either by means of a screw thread formed

page_text: on the neck or otherwise, a cylinder or washer of elastic material, such
as cork or india-rubber, the outer surface of this cylinder being slightly
· conical. A cap or cover of suitable material is applied over the said
elastic cylinder or washer. The interior of this cap or cover is also
made conical, so that when pressed on the said cylinder an air-tight
closing is obtained.
The top of the cap or cover may be printed, stamped, or otherwise
formed with a trade mark or name, and as the said cap or cover is easily
removable it will serve in the case of pocket flasks as a drinking cup,
and it may be-graduated to serve as a measure.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Paul Hubert and Voloy Boissel in the Great Seal
Patent Office on the 4th June 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, Paul
HUBERT, the younger, and VOLOY BOISSEL, both of Bordeaux, in the
Republic of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing, date the Fifth day of December, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors, give!
·and grant unto us, the said Paul Hubert and Volcy Boissel, Her special
licence that we, the said Paul Hubert and Volcy Boissel, our executors,
administrators, and assigns, or such others as we, the said Paul Hubert
and Volcy Boissel, our executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times a
thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "AN IMPROVED METHOD OF STOFFERING FLASKS, BOTTLES, AND
OTHER VESSELS,” upon the condition (amongst others) that we, the said
Paul Hubert and Volcy Boissel, our executors or administrators, by an
instrument in writing under our, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said In-

page_text: evntion; and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Paul Hubert and Volcy Boissel,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and-by the following statement, reference-being had to the Drawing
liereto annexed and to the figures and letters marked thereon, that is to
say :-
This Invention consists in an improved method of stoppering flasks,
bottles; jars, and other vessels in a simple and effective manner, whereby
an air-tight closing is obtained, part of such stoppering serving as a
capsule and as a drinking glass.
To carry out our Invention, we fix on the exterior of the neck of the
flask, bottle; jar, or other vessel, either by means of a screw thread
formed on the neck or otherwise, a cylinder of elastic material, such as
cork or india-rubber. The outer surface of this cylinder is slightly
conical, and may be covered with tin foil pressed into a channel or
groove in the lower part of the neck under the cylinder. A cap or cover
of suitable material and size is applied over the said elastic cylinder.
The interior of the cap or cover is also made conical, so that when
pressed on the said cylinder an air-tight closing is obtained.
The top of the cap or cover may be impressed or otherwise formed
with a trade mark or name. The said cap or cover is easily removeable,
and will serve in the case of pocket flasks as a drinking cup, and it may
be graduated to serve as a measure for taking medicine.
In the accompanying Drawing Figure 1 is a front elevation of a flask
stoppered according to our improved method; Figure 2, section of
same; Figure 8, a part section, shewing the screw thread on the neck
of the bottle for fixing the cylinder; and Figure 4, a detached view of
the cap or cover, serving also as a drinking glass.
a is the oylinder of elastic material fixed on the neck of the flask by
the screw thread b; o is the cap or cover serving when removed as a
glass for drinking the contents of the flask.
In Figure 3 the cylinder a is shewn covered with tin foil d, pressed
down into the groove or channel e, shewn in dotted lines,

page_text: Having thus described our Invention, and the best manner we are
acquainted with for carrying the same into effect, what we claim is, the
employment of an exterior elastic cylinder in combination with a cap or
glass for stoppering flasks, bottles, and other vessels, substantially as
herein-before described.
In witness whereof, we, the said Paul Hubert and Volcy Boissel,
have hereto set our hands and seals, this Thirtieth day of May,
in the year of our Lord One thousand eight hundred and seventy-
