ture, such as certain food products, 'cer. tain drugs and chemlcals, and gun powder,`

which shall be light in weight, inexpensive to manufacture, especially as compared with metal containers, sufficiently strong to retain its shape in handling and to protect the contents, and wholly impermeable to moisture. In accordance with the invention and inner lining or casing, of suitable form and dimensions, iscovered with an interliner of metal foil, yverythin and light but impervious to moisture, with contact of metal to metal at all joints, and an outer casing. The inner lining or casing is suficientlystrong and stili' to furnish a reinforcement for the interliner of metal foil, which preferably has its seams sealed or soldered, and the outer casing protects the rather delicate interlining of metal foil from abrasion. The invention will be more fully explained hereinafter with reference to the accompanying drawing in which it is illustrated as embodied in Va container of suitable form, and in which- Figure l is a view of such a container 1n longitudinal section.

Eig. 2 is a detail view/,also in longitude the metal foil to the innerl and outer casings.

'lhe inner lining or casing a is made of any suitable material, preferably paper board wound upon a mandrel until the desired thickness of wall is secured, the several plies or layers being united by any suitable adhesive, preferably a waterproof adhesive, such as asphalt. rThis tubular inner lining or casing d is provided at each end wlthan inset cap b which stifl'ens the inner llnlng or casing and assists in preservingits shape. The inner lining or casing is preferably shouldered internally, as atI af, ateach end, for the purpose of receiving the cap b and each cap, if desired,

may be held in place by an adhesive. The i cutting away of the inner liningv or casing e to receive theV cap not only furnishes a proper seat for the cap but permits the inner face of the wallto be perfectly smooth.

4It will be understood that one of the caps b is secured in place at one end of the linin or casing a, the goods to be shipped,i o

whatever character they may be, are then introduced and the other cap is forced into place. The two caps b, b, may be secured in placewithin the lining or casing a by means of anyl suitable adhesive.

When the inner lining or reinforcing or supporting form has thus been provided, there is a plied to it, externally, an inter lining c o thin metaly foil, such as thin lead foil.- This isl applied about the body of the inner lining or casing as a rectangular sheet with edges abutting, 4as at c', and secured and sealed by solder,as at 02. Each end is then covered by a cap d of metal, also rela tively thin, and stamped or pressed up, se# curedf and sealed at its edge by solder, as at al', to the metal interlining c with which it is'in contact. The metal 'foil can be very thin, so far as its permeability is concerned, and should be thin for the sake of lightness. It becomes necessary, therefore, to protect` this relatively thin and delicate interlining from abrasion and for this purpose there is provided an outer lining or casing e, also preferably made of paper or paper board by winding the same on a mandrel, with the plies securedby a suitable adhesive, preferably a waterproof adhesive, such as asphalt. At each end-iis then applied a cap f of any suitable material, preferably secured in place by a suitable adhesive or crimped on.

Contact of the metal cap d with the metal v interlining c may be secured in any suitable manner. As shown in the drawing the metal interlining c is carried to the end of the tubular inner lining a and the metal cap d' is extended beyond and pressed down over and into Contact therewith and secured by solder. ln this manner the metal interliningrr is made continuous over the ends 4as well as the sides and seamless and the container becomes, as it is intended to be, impermeable at all polnts, air, moisture and gases being completely excluded from the contents.`

Reliance being placed for impermeability upon the interlining ofmetal foil which, for the sake of lightness, is made so thin as to be very delicate and incapable of retaining its shape, even under its own weight, it is necessary that the inner liner or inner lining or casmg a be relatively strong and stiff so as to provide a proper form and support for the relatively delicate metal foil, so as to reinforce the same and make it possible toA form it,'as well as to make it possible to fill and seal this part of the container before it is introduced into the outer casing. Notwithstanding the provision of adequate support and reinforcement for the metal foil,

such metal foil, if exposed, would be liable to injury, with a loss of its desirable characteristic of complete impermeability and it l is therefore necessary to provide an exterior protect the tected absolutely against penetra/tion of moisture from without. It will also be observed that with a- -proper treatment of the condition.

j It will be understood that the form and dimensions of the container and the character of material employed for the inner and outer casingsas well as the relations of the several parts from the point of thickness may be varied as desired and will be determined in each instance by the character of the goods to be shipped in the container.

I claim as my invention:

1. A container comprising a relatively rigid inner lining or casing of nonmetallic material, relatively stiff and light, a continuous and seamless interliner of metal'foil laid upon the inner lining and coverin the inner lining completely and having al itsl joints hermetically sealed, and an outer protective casing.

2. A container comprising a relatively r1g1d inner linlng or caslng of nonmetalllc material having inserted end caps, a continuous, hermetical interliner of metal foil laid upon the inner lining or casing with end caps of like material in Contact therewith and hermetically sealed thereto, and an outer protective casing also provided with end caps.
