LETTERS PATENT to Charles Moise Jacob, of No. 10, Rue Joubert, in the City
of Paris, in France, Merchant, for the Invention of
IMPROVEMENTS IN
CAPSULING OR SEALING BOTTLES AND JARS."
PROVISIONAL SPECIFICATION left by the said Charles Moise Jacob at the
Office of the Commissioners of Patents on the 14th September 1876.
CHARLES MOISE JACOB, of No. 10, Rue Joubert, in the City of Paris, in France,
Merchant. "IMPROVEMENTS IN CAPSULING OR SEALING BOTTLES AND JARS."
This Invention has for its object improvements in capsuling or sealing bottles and
jars. For this purpose I employ a plastic substance which is applied by simple
immersion and which hardens rapidly on exposure to the air and then forms a
perfectly adhering capsule quite impervious to moisture, capable of receiving metallic
or other colour, and whose cost is much smaller than that of metallic foil or capsules.
The compound which I employ for this purpose is composed of about 25 per cent. of
pyroxaline or gun cotton with about 75 per cent. of a mixture of vinous or other
alcohol and sulphuric ether, to which is added about 2 per cent. of gutta percha and
powdered metallic bronze, gilt, &c., if a metallic appearance is desired, or suitable
colouring matters if it is wished to imitate wax or pitch. The moist collodion thus
obtained is concentrated to a degree suitable for use. This degree of concentration
varies according to the thickness it is wished to obtain and the nature of the article
to be capsuled. The article is dipped cold into this composition, and on being
withdrawn the simple evaporation causes the covering to closely adhere to the
surface and forms a hard and durable skin of any desired appearance. When the
skin of collodion is sufficiently thick, any seal, stamp, or trade mark can be applied
to it. A drawing or label may also be placed on the surface and be then covered
with a thin layer of transparent collodion so as to preserve without hiding it.
In some cases to give it greater solidity I cover the collodion with an amber,
resinous, gummy, or gelatinous varnish. It may also be coated with or come after
a wash of the solution of silicate of soda or potass of about 35° Beaumé, which
ensures its adherence to the glass.
It is evident that this method of capsuling or sealing may be employed for many
purposes which it is needless to enumerate.

CHARLES MOISE JACOB, of No. 10, Rue Joubert, in the City of Paris, in France,
Merchant. "IMPROVEMENTS IN CAPSULING OR SEALING BOTTLES AND JARS."
This Invention has for its object improvements in capsuling or sealing bottles
and jars. For this purpose I employ a plastic substance which is applied by simple

perfectly adhering capsule quite impervious to moisture and capable of receiving
metallic or other color. The compound which I employ for this purpose is composed
of about 25 per cent. of pyroxaline or gun cotton, with about 75 per cent. of a
mixture of vinous or other alcohol and sulphuric ether, to which is added about
2 per cent. of gutta percha and powdered metallic bronze, gilt, &c., if a metallic
appearance is desired, or suitable coloring matters if it is wished to imitate wax or
pitch. The moist collodion thus obtained is concentrated to a degree suitable for
use. This degree of concentration varies according to the thickness it is wislied to
obtain and the nature of the article to be capsuled. The article is dipped cold into
this composition, and on being withdrawn the simple evaporation causes the covering
to closely adhere to the surface and forms a hard and durable skin of the desired
appearance. When the layer or skin of this collodion is sufficiently thick, any seal,
stamp, or trade mark can be applied to it. A drawing or label may also be placed on
the surface and be then covered with a thin layer of the collodion, so as to preserve
without hiding it.
In some cases, to give it greater solidity, I cover the collodion with a varnish or
with resin, fatty matter, gum, or gelatine. It may also be coated with or come
after a wash of the solution of silicate of soda or potass of about 35° Beaumé,
which ensures its adherence to the glass, or they can be mixed in the preparation
of the collodion.
It is evident that the method of capsuling or sealing may be employed for many
purposes which it is needless to enumerate.
I claim as my Invention, without limiting myself to the exact mixtures and
proportions indicated, the employment for capsuling bottles, flasks, and other
vessels of glass, porcelain, metal, or other material, of moist collodions employed
either alone or with the addition of coloring or metallic substances to modify its
appearance, and other matters suitable to render it stronger and more durable.
In witness whereof, I, the said Charles Moise Jacob, have hereunto set my
hand and seal, this Tenth day of March, in the year of our Lord One
thousand eight hundred and seventy-soven.
