Description

tr er FREDERICK COATES,- OF CINCINNATI, OHIO, AS SIG-NOR TO FEDERAL PRODUCTS,
COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO- PAPER-COATING COMPOSITION.
1,414,256. a No Drawing. I
More particularly the invention relates to,
a paper oil-proofing composition and the method of manufacturing the same.
It is a well understood fact that paper cans or containers which are used for the packing or storing'of certain classes of substances such as butter, lard and other greases, as well as for storing and packing various other commodities, must be rendered proof against action by oil or the like.
One important object of the present invention ,is to provide an improved composi-' tion for oil-proofing paper.
A second important object of the invention is to provide an improved composition for coating the interior or exterior of paper containers such as cans, or cartons. 1
A third important object of the invention is a provision of an improved composition for this purpose which'dries very slowly, does not sour or decompose readily and forms ,a superior preservative for the container.
A fourth important object of the invention is to provide an improved composition of this character which is elastic in its nature so that it will not crack, or spall off from the container as do brittle compositions.
Vith the above and other objects in view as will be hereinafter understood the invention consists in general of a certain novel composition of matter and an improved manner of manufacturingthe same. a
In the preparation of this composition there is taken one part of gelatin and two parts of water. The gelatin is immersed in the Water, both being at the ordinary atmospheric temperature and the gelatin and water arethen allowed to stand for two hours, remaining during this period at substantially the same temperature as the atmosphere. At the end of the two hours heat is applied and the temperature is raised to 120 Fahrenheit. When this temperature has been i one part of acetone.
reached there is added to the mixture one part of glucoseand one-half part of glycerine. This mixture is kept at 120. In the meantime a second mixture is made which consists of two parts of water, one and oneseparately and then merging the two the resultant compound dries very slowly and remains sweet, and having practically no tendency to sour. It is also found that this composition, formed in this manner, makes a highly efficient preservative which possesses such an amount of elasticity, as to render it peculiarly adapted for coating paper cans and other containers.
Having thus described the invention, what is claimedas new, is
1. The process of forming a paper oilproofing composition which consists 'in merging two mixtures, one of said mixtures containlng water, gelatin, glucose and glycerine and the other of said mixtures containing water, glucose, glycerine and acetone. if 2..The processof forming a paper oilproofing composition which consists in mergtin, one part of glucose and one-half part of glycerine, the other of said mixtures containing two parts water, one and one-half parts glucose, one-half part of glycerine, and
3.,The process of forming a paper oilproofing composition which consists in merging two mixtures, one of said mixtures being formed by mixing two parts of water with one part of gelatin at normal atmospheric temperature and allowing the same to stand for two hours, raising the temperature of the water and gelatin to 120, adding one part of glucose and one-half part of glycerine thereto and maintaining the mixture at 120, the other of said mixtures being Specification of Letters Patent.
