Substances, and Process for Preparing same.
We, EDUARD MAY, of IV Rubensgasse 13, and EMIL KÜHNE, of IX Kolengasse 17,
both in Vienna, Austria, Rentiers, do hereby declare the nature of this invention to
be as follows:-
This invention relates to a new article or medium, which when employed as a
wrapper or cover for meat, fish, butter, game and other articles of consumption, will
ensure the preservation of same in a fresh condition for a considerable time.
The object of the invention is to produce an extremely cheap, easily handled and
reliable preservative preparation for general use. ·
The following substances namely: paper, pasteboard, textile fabrics, bladder, the
intestines of cattle, etc. may serve for this purpose the property of acting as a
preservative being imparted to them by dipping and so impregnating them in a
solution consisting of
About litre of methyl alcohol
About litre of pure spirit
About
litre of glycerine, and
About 10 grammes of a fluorine compound or antiseptic.
In the case of paper in continuous lengths it is sufficient to unwind the paper
from one roller, pass it through the vessel containing the impregnating liquid and
immediately wind it round another roller.
The method of employing the preservative medium consists in applying the same
closely to the piece of meat etc. to be preserved, or rolling it tightly once or twice
around the latter and then covering this wrapper with a layer of ordinary paper or
textile fabric.
The material in question derives its preservative action by impregnation with
the above mentioned liquid, from which the spirit evaporates and the glycerine
or filling or sealing material and fluorine compound or antiseptic remain behind in
a fine state of division in the paper or material.
:
Practical experiments have shewn that meat, fish, butter, etc., wrapped in the
preservative paper prepared in the manner described above, remained perfectly fresh
and edible for a long time, so that no doubt can be raised with regard to the
commercial advantages and also the innocuous nature of the material.

We, EDUARD MAY, of IV. Rubensgasse 13, and EMIL KÜHNE, of IX Kolengasse 17,
both in Vienna, Austria, Rentiers, 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 new article, or medium, which, when employed as a
wrapper or cover, for meat, fish, butter, game, and other articles of consumption,
will ensure the preservation of same in a fresh condition for a considerable time.
The object of the invention is to produce an extremely cheap, easily handled and
reliable preservative preparation for general use.
The following substances namely: paper, pasteboard, textile fabrics, bladder, the
intestines of cattle, etc., may serve for this purpose, the property of acting as a
preservative being imparted to them by dipping and so impregnating them in a
solution consisting of about litre of methylalcohol, about litre of pure spirit such
as alcohol, about litre of glycerine, and about 10 grammes of a fluorine compound
or antiseptic. The fluorine compound may be a mixture of fluorine with radicals for
The antiseptics
instance ammonia, the mixture being more or less soluble in water.
may be a coinpound of boron and benzoin.
In the case of paper in continuous lengths, it is sufficient to unwind the paper from one
roller, pass it through the vessel containing the impregnating liquid and immediately
wind it round another roller.
The method of employing the preservative medium consists in applying the same
closely to the piece of meat, etc., to be preserved, or rolling it tightly once or twice
around the latter and then covering this wrapper with a layer of ordinary paper or
textile fabric.
The material in question derives its preservative action by impregnation with the.
above mentioned liquid, from which the spirit evaporates and the glycerine or filling
or sealing material and fluorine compound or antiseptic remain behind in a fine state
of division in the paper or material.
Practical experiments have shewn that meat, fish, butter, etc., wrapped in the
.preservative paper prepared in the manner described above, remained perfectly fresh
and edible for a long time, so that no doubt can be raised with regard to the
commercial advantages and also the innocuous nature of the material.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what.
we claim is
.1. The improved: preservative article or medium for meat, game, fish, poultry,
butter, and other articles, consisting of paper, pasteboard, textile fabrics, bladder,
intestines or suitable material, treated or impregnated with glycerine and an
antiseptic substance (a fluorine compound) which is incorporated therein in a very
fine state of. division by impregnation, by means of a solvent such as alcohol,
substantially as described.
2. A process for preparing a preservative article or medium, consisting in
immersing paper, pasteboard, textile fabrics, intestines, and, bladder, or like suitable
material in a liquid containing antiseptic and filling or sealing materials dissolved in
alcohol, substantially, as described.
3. As an impregnating preparation for the production of the preservative article or

page_text: material described in the first claim, a solution consisting of methylalcohol, spirit,
glycerine and a fluorine compound in substantially the proportions specified.
