PACKAGE FOR MEDICINES, 8&(2.

SPECIFICATION fort-ling part of Letters Patent N 0. 668,273, dated September 18,

Application filed mam 24. 1960. semi No. 6.9552; (Nd model.)

To all whom it may concern:

Be it known that I, LUTHER EMBRY Moonn, residing at Marietta, in the county of Cobb and State of Georgia, have made certain new and useful Improvements in Packages for Medicines, &c., of which the following is a specification.

My invention has for its object to provide a package for medicinal salts, powders, and granulations of an effervescent or deliquescent nature injuriously affected by atmospheric conditions, by heat, or bycontact with acids or alkalies.

It is well known that many drugs or chemicals in themselves very useful for pharmaceutical purposes are so unstable that they become practically worthless by exposure to the atmosphere, and when they are kept in the druggists stock for any length of time, shipped from one place to another, or sold to a customer in packages containing more than one dose, necessitating the leaving of one or more doses in a broken package, they deteriot-ate. stances difficult to handle, and myinvention is designed to overcome such difficulties.

The invention consists in certain details of construction and arrangement of the parts, which I shall hereinafter fully describe and claim. 7 7

Reference is to be had to the accompanying drawings, forming part of this specification, in which like characters of reference indicate corresponding parts in all the views.

Figure l is a perspective view of two layers of paper and their intervening layer of oement preparatory to pressing and cutting into the shape shown in Fig. 2. Fig. 2 is a perspective view of a completed section of the package. Fig. 3 isa similar viewof the package complete, and Fig. 4 is a transverse section of the same.

To form my improved package, I take two sheets of paper or other suitable fibrous material, cut them to the desired size, depending upon the size of the dose which the package is intended to contain, and stamp them into the dished form shown in Fig. 2. As

illustrated, A designates the outer layer,composed of an absorbent fibrous material, preferably paper which is soft and porous, and B designates the inner layer, composed of These conditions make these subpaper or like material having a smooth firm fih'ishFaTtidTlTerefore repellant. The two layers A and B are secured together by a cement Dwhich is a poor conductor of heat and im-' pervious to paraffin and with which the contacting face of the layer B is coated, and one section of my improved package is thus formed, as shown in Fig. 2. Each package consists of two sections or parts prepared in the manner just described above, placed one upon the other and inclosing the dose, their abutting flanges or rims 0 being glued together. The package is then hermetically sealed by dipping it into a melted mixture E of paraffin, spermaceti wax, and resin, when the article is complete.

It is to be especially noted that I do not merely employ a package ofpaper hermetically sealed with paraffin, wax, &c., for I have found that such a package is practically worthless for the purpose for which mine is intended, because the paraffin when hot will penetrate the pores of paper, thus causing many effervescent drugs to become soft and form an adhesive mass which is slow to effe'rvesce. Furthermore, if the paraffin is applied to the sections of the package before they are sealed pressure and heat will be required to seal it, thus giving rise to the same difficulty and being very troublesome; but, on the other hand, each section of my package is composed of an outerlayer of coarse or porous fibrous material and an inner layer of a smooth firm surface with an intervening sheet or coat of cement impervious to the heat and sealing mixture, and consequently the sealing mixture will penetrate the package as far :as the outer layer, but will be checked by the cement, which confines the saturation to the outer coat and reduces the degree of heat to which the contents of the package are subjected. It is also to be noted that the impervious coating on the outside of the package, completely inclosing'the same, renders permanent all printing on the outside layers A, identifying the contents and the manner of using.

I do not confine myself to the exact size or shape of the package illustrated, as it may be changed in these respects without departing from the scope of my invention.

Having thus described myinvention, what 2 Y saevs 2. The herein-described package for efferv vescent. or deliquescent drugs or chemicals, comprising dished sections each formed of an outer layer of absorbent fibrous material and an inner layer of repellent fibrous material, a

layer of cement between the layers of fibrous material, said sections being connected together, and a coating of parafiin inclosing the said connected sections,- as and for the purpose set forth. v
