HENRY CLAY GROOKER, OF MILWAUKEE, WISCONSIN.

HERMETICALLY-SEAL ED PAPER PACKAGE.

SPECIFICATION forming part of Letters Patent No. 248,146, dated October 11, 1881. Application filed July 7, 1880, (No modeL}.

To all whom it may concern Be it known that I, HENRY G. GRooKER, of Milwaukee, Milwaukee county, Wisconsin, have invented a new and Improved Hermetically-Sealed'Paper Package, of which the following is a-specification.

The object of my invention is to provide a new and improved package which is hermeticallyclosed,'andis especially adapted forspices, coffee, baking-powder, and the like articles.

The invention consists of a filling of the'ma' terial, afolded paper wrapper pasted together at the joints and inclosing said material, and

' having a superficial coating of paraffine for .both hermetically closing the pores and her metically sealing the joints and an exterior wrapper inclosing this.

The invention also consists in the process of putting up this package, as hereinafter more fully described.

111 the accompanying drawings, Figure l is a perspective view of my improved package,

and Fig.2 is a longitudinal sectional elevation of the same.

sponding parts.

A package, A, is made of any desired kind of paper, and is filled with the desired material, and then sealed in the ordinary manner. The package. is then steeped in abath of melted wax, paraffine, or any other suitable material that will effectually close all thejoints of the package air and water tight. The package is then provided with an ornamental cover or wrapper, B. This package is especially adapted for aromatic substances-such as spices, coffee, tca-and also for powdered and other substances that must be protected from moist. ure-suoh as baking and yeast powders and the like I am aware that packages have heretofore been made of paper treated with wax, paraffine, or like materials, but this I do notclaim. This sort of paper cannot be madeinto a stable package, for the reason that the paper,'when impregnated with paraffiue, will not take the paste, and besides, as the paraffine is onboth sides of the paper, the contents of the package are. contaminated by direct contact with the paraffine. Withmyinventiononlycleanpaper is next to the contents, and the-paper being pasted before the paraffine is applied, a stable package results, while the paraffine closes up all seams and renders the package air-tight.

I am aware of English Patents No. 577 of 158 61, and No. 2419,51, of 1863, and Ido not claim nything described thefieiim My invention is distinctive with respect to the subject-matter of the foregoing patents, in that the package is made complete, as a perfeet mechanical structure, by having its folds permanentlyand securely pasted before it is dipped in the paraffine, so that the packagedoes .not rely upon the paraffine for cementing its join t, but the'paraffine has the special function of preservigg the stability of the pasted joint by rendering'it impregnable to atmospheric influences, in addition to its other advantages of rendering thepaper impervious to moisture and hermetically sealing the package. If the folds were not first 'pasted, the parafiine of itself would not be sufficient, except for a very limited time. The pasting of the edges, therefore, becomes an important step in preceding the treatment of the package by paraffine, in preserving the stability ofthe hermetically-seated package.

Havingthus described my invention, I claim as new and desire to secure by Letters Patent- 1. A package consisting of a filling of material substantially as described, afolded paper wrapper inclosing the same and having a su- HENRY CLAY OROGKER.
