PROVISIONAL SPECIFICATION.
Improvements Protective Coverings for Meat Extract and other
Moist or Water-containing Substances.
A communication from abroad by JULIUS MAGGI, of Kempt-thal, Switzerland.
I, WILLIAM LLOYD WISE, of No. 46 Lincoln's Inn Fields, in the County of
London, Consulting Engineer and Patent Agent, do hereby declare the nature of this
invention to be as follows :-
Gelatine and similar glue containing compounds used in the manufacture of
casings coverings or containers (hereinafter called containers) for articles of food, are
very hygroscopic, consequently the substances enclosed in such containers are liable to
rapid deterioration, especially in moist warm weather.
This is particularly the case with neat extract and salt, etcetera, which, enclosed in
gelatine capsules or small gelatine tubos, constitutes an article of commerce under
various designations.
Gelatinous containers filled with water-containing substances have for the purpose
of protection been enclosed in a covering or envelope of tin foil or prepared paper
made air and water tight. But experience has shewn that the protection thus afforded
is inadequate and that consequently the gelatine is liable in time to undergo
putrescent fermentation and the article designed for consumption to become dangerous
to health. Even should the gelatine become decomposed only to a much more limited
extent the ordinary protective covering adheres to the gelatine or, so to speak, unites
intimately with it so that its removal becomes a tedious operation, and an unappetizing
appearance is imparted to the article.
Now this invention has reference to a compound. protective covering designed to
obviate the foregoing disadvantages. For this purpose the extract of meat or other
substance to be protected is enclosed in one or more capsules or small tubes suitable
for consumption as heretofore and this or these is or are in turn enclosed in a larger
casing or sheath made in parts of gelatine colored or not colored so that one part
overlaps the other where they join; the joint is made tight with a closure of fat, and
over the above compound covering is afterwards placed the usual covering of tin foil
or water-proof paper.
In this way not only is the inner capsule or small tube (or each of them if there
be more than one) protected against direct pressure but also there is produced by
these means a thin layer of air which envelops the article of food, and which keeps
away external noisture and also protects the said article from all sudden external
influences of changes of temperature, in a manner similar to that of the influence of
double windows upon the temperature of rooms. A very pleasing appearance can be
given thereby to the goods.
In lieu of covering with tin foil or water-proof paper the casing or sheath that
encloses the inner capsule or tube or tubes the casing or sheath may be protected
directly against external moisture of the air by treatment with chemical agents known
to render gelatine insoluble, or it may be covered by dipping with an outer protective
covering or coating of collodion celluloid wax, or solid fat.

Improvements in Protective Coverings for Meat Extract and other
Moist or Water-containing Substances.
A communication from abroad by JULIUS MAGGI, of Kempt-thal, Switzerland,
Manufacturer.
I, WILLIAM LLOYD WISE, of 46 Lincoln's Inn Fields, in the County of
London, Consulting Engineer and Patent Agent, 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:-
Gelatine and similar glue containing compounds used in the manufacture of
casings coverings or containers (hereinafter called containers) for articles of food, are
very hygroscopic, consequently the substances enclosed in such containers are liable
to rapid deterioration, especially in moist warm weather.
This is particularly the case with meat extract and salt, etcetera, which, enclosed
in gelatine capsules or small gelatine tubes, constitutes an article of commerce under
various designations. Gelatinous containers filled with water-containing substances
have for the purpose of protection been enclosed in a covering or envelope of tin
foil or prepared paper mado air and water tight. But experience has shewn that
the protection thus afforded is inadequate and that consequently the gelatine is liable
in time to undergo putrescent fermentation and the article designed for consumption
to become dangerous to health. Even should the gelatine become decomposed only
to a much more limited extent the ordinary protective covering adheres to the
gelatine, or, so to speak, unites intimately with it, so that its removal becomes-a
tedious operation, and an unappetizing appearance is imparted to the article..
Now-this-invention-has-reference to a compound_protective covering designed to
obviate the foregoing disadvantages. For this purposo the extract of meat or other
substance to be protected is enclosed in one or more capsules or small tubes suitable
for consumption as heretofore and this or these is or are in turn enclosed in a larger
casing or sheath made in parts of gelatine colored or not colored so that one part
overlaps the other where they join; the joint is made tight with a closure of fat, and
over the above compound covering is afterwards placed the usual covering of tin foil
or water-proof paper.
In this way not only is the inner capsule or small tube (or each of them if there
be more than one) protected against direct pressure, but also there is produced by
these means a thin layer of air which envelops the article of food, and which keeps
away external moisture and also protects the said article from all sudden external
influences of changes of temperature, in a manner similar to that of the influence of
double windows upon the temperature of rooms. A very pleasing appearance can be
given thereby to the goods.
In lieu of covering with tin foil or water-proof paper the casing or sheath that
encloses the inner capsule or tube or tubes, the casing or sheath may be protected
directly against external moisture of the air by treatment with chemical agents known
to render gelatine insoluble, or it may be covered by dipping with an outer protective
covering or coating of collodion, celluloid, wax, or solid fat.
In the annexed sheet of drawings Figs. 1 to 7 illustrate by way of example a
compound protective covering according to this invention.
In Figs. 2 and 3 is shown a small gelatine tube filled with meat extract a as
described in my previous specification No. 10229 of 1889, and in Fig. 1 is shown a
larger casing or sheath made in parts of gelatine.
In Figs. 4 and 5 I shew in longitudinal and transverse section the small tube b with
its contents, i.e., meat extract a, enclosed within the larger gelatine casing or
sheath d, so that there remains so to speak a layer of air y between the small tube b
and the casing or sheath d. The joint where the parts of the larger gelatine casing
or sheath d close one over the other can be provided with a closure or seal of fat

page_text: Around the casing or sheath d is or may be arranged an outer protective covering of
tin foil, water-proof paper, collodion, celluloid, wax or solid fat.
In Figs. 6 and 7, the small tube b filled with meat extract etc. as before, is further-
more provided with an envelope f of tin foil or water-proof paper, over which is
placed the gelatine casing or sheath d as shown. In this case also, the joint between
the parts of the gelatine casing or sheath d can be provided with a closure or seal
of fat x.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. A compound protective covering such as hereinabove described for meat extract
or other moist or water containing substance or substances consisting of inner and
outer coverings of gelatine or other similar hygroscopic material, namely a capsule or
small tube (or capsules or small tubes) of gelatine or similar hygroscopic material
filled with the meat extract and salt or other substance or substances to be preserved,
and a covering or sheath of gelatine or the like surrounding and enclosing the said
capsule or tube or capsules or tubes as set forth.
2. The manufacture of the herein described article of commerce, consisting of a
capsule or tube or capsules or tubes of gelatine or other similar hygroscopic material
filled with an article or articles of food such as meat extract with condiments and
enclosed with a surrounding filui of air in a gelatine casing or sheath made in parts
with an air tight joint, the said parts being chemically treated to render the same
insoluble, or provided with an outer protective covering of tin foil or water-proof
paper or of collodion, celluloid, wax or solid fat as set forth.
