This invention relates to paper pulp containers, such as pails, cans, and the like, designed for packaging and shipment of various articles of merchandise, and more par- 5 ticularly, food products containing moisture or grease or both.
The principal object of the invention is to produce a thoroughly practical and inexpensive container of paper pulp or other fibrous substance that will be both water and grease proof.
Paper pulp pails and cans have heretofore been interiorly coated with parafiine with a view to rendering them water-proof, and
it they have also been coated with sodium silicate to render them grease-proof; A paraffine coating, however, is not grease-proof, nor is a sodium silicate coating water-proof. I have found that a pulp container may be 24 rendered grease-proof by coating it with animal or vegetable glue, and it may also be rendered water-proof by applyin to the surface of the glue coating'a very t in coating comprising a solution of cellulose ester, such 25 as cellulose-acetate or nitro-cellulose.
' Such a cellulose coating is water proof and also, when of substantial thickness, grease proof, but is very expensive; hence, to lower the cost, I propose to utilize a gelatin coating to insure the property of imperviousness to grease and oils, and to employ thereon a thin coating of acellulose ester to prevent access of moisture to the gelatin coating.
Accordingly, in preparing-the article, I take an ordinary paper pulp or other fibrous 1 can, pail or the like, and apply, preferably to the interior surface thereof, a relatively thick coating of gelatin, either an anmial gelatin such as animal glue, or a Vegetable coating such as starch or dextrin. This coating may be applied in any of the well-known ways, such as dipping, brushing or spraying. When the gelatin coating is thoroughly dry, I then apply to the surface thereof a thin coating of a solution of a cellulose ester, for example, cellulose-acetate or nitro-cellulose, permitting the same to thoroughly dry. This water-proof coating of a cellulose ester maylikewise be applied in any of the known ways,

hold of and adhere strongly to the underlying I gelatin coating.
By the foregoing process of treating, a
pulp container, I provide a universal container for all substances, solid or liquid, hot or cold, containing either moisture, or oil or grease, or both, which will not permit the contents to seep through the walls of the container.
I claim:
1'. A paper pulp receptacle impervious to hot and cold substances that contain water, oil or grease, the said receptacle having a coating of gelatin applied to the paper and over the gelatin havm a coating of cellulose ester containing a mo lfying agent to render the said coating layers strongly adherent to each other.
2. A paper pulp receptacle impervious to hot and cold substances that contain water, oil or grease, the said receptacle having a coating of gelatin applied to the paper and over the gelatine having a relatively thin coating of cellulose ester containing a modifying agent to render the coating layers strongly adherent to each other.
