WILBUR L. .w'ruen'r, or FULTON, NEW YORK. I
ART OF RENDERI'NG PAPER AN D OTHER FIIBROUS MATERIAL IMP ERVIOUS '10 GREASE.
To all whom it may concern: I
Be it known that I, VVILBUR L. WRIGHT, a citizen of the United States of America, and resident of Fulton, county of Oswego', State of New York, have invented certain new and useful Improvements in and Relating to the Art of Rendering Paper and Other Fibrous Material Impervious to Grease, of which the following is a specification.
This invention relates to the art. of rendering paper andother fibrous material impervious to grease and the objects and nature of the invention will be readily understood by those skilled in the art in the light of the following explanation of what I now believe to be the preferred ex pression and embodiment of the invention.
The object of. the invention is to provide paper or other fibrous material either impregnated with or having a coating of improved material that establishes a barrier against the passage of grease, material that is not soluble in grease, and that can be applied to the paper or other material, either hot or cold,,and composition for such purpose. x With these and other objects in view, the invention consists in a composition, or in paper or.otherfibrous material impregnated.
with or having a'coating of such composition, where suchcomposition embodies casein.
- The basis of the composition of my invention is characterizedby a body, adhesive, or gelatinous solution composed of a casein whether or not other ingredients are included to control the flexibility and hardness of the coating formed by the com-' position, or to render the same waterproof, or to attain other qualities not inherent in the casein solution.
The casein solution can various methods well known in the art.
For instance, I ing of water casein is dissolved in the presence of heat.
As an example, a grease proofing composition embodying my invention can be composed of. say two hundred parts, more orfless be formed by to those skilled can use a solvent consist- Appl ication filed May 12,
. a coating to provide an improved u'cts such as and ammonia by which the 1920. Serial No. 380,752.
of casein; ammonia, ten parts more or less; water one thousand parts more'or less; and
glycerine (or some other ingredient to mixture at a suitable temperature (say about 175 Fah.) and stir until the casein has dissolved. Before using the composition,
I usually filter or decant the same to remove any possibility of remaining undissolved portions of casein.
This composition can .be applied to the paper or other material, eitherJhot or cold. I
This is a material advantage in practice. Thev composition is usuallyapplied to form is of particular advantage for coating the inner surfaces of paper containers .for
grease-like products particularly food prod lards and artificial lards and' Theiproportions stated can ,begreatly 'varied and various other ingredients can be added to the composition and other ingredients can be substituted, for glycerine all without departingfrom my invention, 1. e. utilizing casein to form the body or basis of the composition.
What I claim is 1. A paper container for food products interiorly grease-proofed by a composition of casein containing a smal percentage of flexibility ingredient.
2. A paper material containerfor food' products, grease-proofed by a 1 layer .of
casein composition.
' 3. A paper material container.. having an internal grease-proofin layer composed of a composition of dis so ved casein rendered flexible by glycerine.
