CONTAINER.

Specification of Letters Paten Patented Feb. 20, 1917.

Application filed June 28, 1913, Serial No. 776,202. Renewed July 3, 1916. Serial No. 107,465.

To all whom it may concern:

Be it known that I, CHARLES W. SHEVLIN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Container, of which the following is a specification.

My invention relates to the provision of a container, or tubular receptacle made from a tissue infused or impregnated with a suitable substance to render the article as a whole'impervious to air, moisture, or liquids,

. so that the receptaclemay be used either for containing liquids and greas substances, the -same being proof against lea age of the most penetrating of such substances; or for conprote'cting same from the action of the exterior air or moisture.

As is known, when fibrous articles are impregnated so as to render them impervious to water, theyare rendered unsuitable for gluing with any of thesubstances now employed for such a purpose. Besides this,

glue or any of the known adhesives arenot desirable substances to use in the presence of moisture, as the moisture with the glue substances, besides impairing their adhesive properties, affords conditions favorable to the growth of bacteria, which growth is ordinarily known as putrefaction. The use of,

such metals as are available is hardly less undesirable than glue, as the available metals in the resence ofair' and moisture undergo oxi ation which is liable to cause variouschemical changes in substances present and subject to such action.

It has, therefore, been one of the problems whicl-r confronted me, and one of the objects of my present invention, to arrive at a method of forming such a container, with- .out using any of the known adhesives-or available metals for securing the outer end of the outer fold or casing, so that it will not be liable to disengagement. It will be understood that the integrity of my packet e in handling largely depends upon "t e strength of the outer casing, as the impre nation of the tissue causes considerab e weakening, and the impregnating materials, while permitting some degree of adhesion between successive layers, are not what are I generally regarded as" adhesives.

I attain the above objects by a preferred form of cc ntainer illustrated in the accompanying drawing, in which' Figure l is a central vertical section through a completed container; I

Fig. 2 is a fragmentary perspective view of the outer casing of the container in position for lo1king, the impregnated liner being shown partially withdrawn; and

Fig. 3 in a fragmental plan of the two ends of the casing portion of the blank.

Similar reference characters designate similar pal ts throughout the several views. In carrying out my invention I take a sheet of fibrous material, as designated by the numerzl 5, preferably a suitable grade of paper, of a length and width commensurate with the size and length of the container required, and, at one end thereof, I form a spear head, 5", preferably of the shape show: 1 in Fig. 3. It will be noted that the edges of the blank are tapered at 5, to

a the inner ortions of the shoulders of the spear head 5, so that when the casing is made into t cylinder, the edges 5 will be disposed sp: rally in the circumference of the cylinder, aid in this way will be caused to remain snugly in position, and will not be liable to be rolled back through handling or accident. It will be seen that this construction will hcld the edges 5}? in place even if no adhesive whatever were used.

At a suita ble distance from the spear head 5", to form a casing'of the desired size, I provide a trans verse slot 5, into which the said spear head 5 is forced, the shoulders 5 of the said spear head binding same in place.

The lining; portion of the blank, 6, having first been impregnated with, in this lease the linin thus causing them to adhere to-' gether. he inner portion or lining is thus impregnated while the outer casing remains only slightly coated and unimpregnated, thus rendering the package walls moisture proof, while, at the same time, the outside wall retains its original strength, the spear being permanently sealed in place between the inner face of the casing and the outer fold of the lining.

I-prefer to make the two end closures, 7 and 8, as follows: A circular sheet of paper or tissue is formed in a die so as to have a turned up outer edge or periphery, 8*,

10 making a cup-shaped member. One of which cup-shaped members, after the same has been impregnated with paraflin, or other suitable impregnating substance, is then inserted or forced into the cylinder from each end, as very clearly shown in Fig. 1. The

form supporting the bottom member, 8, being heated, the parafiin is caused to adhere or unite with the impregnated lining at that point, and, to further insure its stability,

staples, 9, are driven through the cylinder and the flange 8 of the bottom member 8 at suitable intervals upon its periphery. The metal of the staples in this case is sufficiently removed from proximity to the contents of the container as to be free of fear of the contamination thereof. To still further make the union complete between the flange, 8", of the bottom and the inner lining, 6, at their point of contact, a small quantity of melted parafiin is allowed to run into the crevice between the members while they are still hot, and there allowed to cool with them. As the mandrel upon which the top, or member 7, is inserted, is not heated,

the side or flange 7 does not adhere to the lining 6, but is-merely held in. place by a force .fit, thus allowing'its removal without in any way marring or injuring the properties of the "package as a whole. But, in

40 case it is desired to have the package absolutely sealed, the top may be heated and p sealed the same as the bottom after the contents have been placed inthe container.

For further: protection, another cupshaped member, 10, formed exactly like the cup=shaped members 7 and 8, with the exfception that it is sufliciently larger 'in diameter to fit over the ,outside of the cylinder, may thenbe placed over the end holding the cup shaped member 7. Such an additional cover, 10, not only afi'ords greater protection from contamination, .but also provides the space 11, which serves to pro tect the top of the contents ofthe package from radiation, and into which space 11 may be placed directions for use of the contents and advertising material.

Having described my invention, what I claim as new and desire to secure by Letters Patent is 1. A cylindrical container comprising a blank of fibrous material, one end of which said blank is formed into a spear head, a transverse slot being provided in said blank to receive said spear head to form a circn: lar wall or casing for said container, the remainder of said blank being impregnated with an impervious solidifying substance and disposed inside of said casing so as to contact therewith and adhere thereto by reason of the solidification of said substance.

2. A cylindrical container comprising a blank of fibrous material, one end of which said blank is formed into a spear head, a transverse slot being provided in said blank to receive said spear head to form a circular wall or casing for said container, the remainder of said blank being impregnated with wax and disposed inside of said casing so as to contact therewith and adhere thereto by reason of the solidification of said wax.

3. A cylindrical container comprising a casing formed of a blank of fibrous material, one end of which said blank is formed into a spear head, a transverse slot being provided in said blank to receive said spear head to form said casing, and a fibrous lining for said casing being impregnated with an impervious solidifying substance and disposed inside of said casing so as to contact therewith and adhere thereto by reason of the solidification of said substance.

4. A cylindrical container comprising a casing formed of a blank of fibrous material, one end of said blank is formed into a spear head, the edges of said blank being tapered from the broadest part thereof-to the shoulders of said spear head so that said tapered edges will be disposed spirally upon the outside of the finished container, a transverse slot being provided in said blank to receive said spear head to form said casing", and a fibrous lining for said casing being impregnated with vaX and disposed. inside said casing so as tocontact there'witl1 and adhere thereto by reasin tion of said wax I In testimony whereof I/ha've hereunto set my hand in the presence of two witnesses. cnARnns' w. sHEvLm.
