'23, 1937 PATENT ()FFECE aoraeea NONCORROSIVE LKNED C(QNTAENER Richard S. Rheem, Oakland, fialifi, assignor to Rheem Manufacturing Company, Richmond, Califl, a corporation of California Application September 12,1934, Serial No. 743,679

2 Claims.

The invention relates to heavy duty metallic containers or drums usually formed of sheet steel and designed for use in shipping and storing liquids and the like attendant with a corrosive action on the steel or other metal forming the body of the container, and more particularly the invention relates to containers of this character provided on the interior thereof with a noncorrosive liner.

The use of containers, such as barrels and drums for shipping and storing liquids and the like having corrosive effect on the material of which the drums are constructed, have heretofore been attempted and such containers have been lined on the interior with a protective sheet of some non-corrosive material. The mere provision of such a liner has been more or less satisfactory where all the strain on the liner is outward and thereby such strain may be readily absorbed by the sides and ends of the drum. The problem however arises where it is desired to use the drums for shipping and storing substances such as fruit juices and other edible products, since for this use, the interior of the drums are subjectedto an intense evacuation operation as part of the sterilizing and sealing process. Thus the liners as ordinarily provided on the drums, collapse and become so damaged during the evacuation action, as to render them useless or effect a change in the capacity of the container. It has also been proposed to form the drum with steel walls which have been plated or otherwise formed on one side with a coating or covering of non-corrosive material, but such type of stock precludes welding the drum parts or seams together, since in the welding process the steel body material is forced through the noncorrosive shell. As a result of the foregoing, the storing and shipping of the substances aforesaid in the large drums has heretofore been deemed feasible only with the use of drums having side and end walls entirely of a non-corrosive material throughout. Such a construction however is prohibitive from a commercial standpoint and therefore to date heavy duty steel drums have not been utilized in any appreciable extent for the purpose explained.

In accordance with my invention, and it is one of the principal objects thereof, to construct the drum in a manner insuring complete protection against corrosion while at the same time making possible the production of the drum at a minimum cost. It may be mentioned at the outset that my invention does not involve so much the provision of entirely new elements separately, as it does a utilization of a number of more pr less known elements functioning in a different manner than heretofore and combined in a new and novel form. It is, therefore, another feature of my invention to provide a drum in which various parts thereof known to be practical, are associated in a manner rendering the drum of more improved design and construction than drums heretofore made including said parts.

A further object of the-invention is to provide a drum of the character described in which the parts at the points of connection are of such form that they may be connected in an effective manner.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawing and description may be adopted within the scope of the invention asset forth in the claims.

Referring to said drawing:

Figure 1 is a longitudinal sectional view of a drum constructed in accordance with my invention.

Figure 2 is fragmentary transverse sectional view of the drum.

Figure 3 is an enlarged sectional detail view of the joint between the side and end wall of the drum.

In the preferred embodiment of the invention the container or drum 2 comprises an outer body 3 of ordinary steel, formed as a cylinder and constituting the main supporting element of the sides of the drum. Fitting against the inner side of the body 3 and coextensive therewith both longitudinally and circumferentially is a liner 4 formed of a non-corrosive metal such as stainless steel. Both the body and liner are made from fiat sheets secured together along a longitudinal seam, the joints being preferably efiected by welding the side edges of each of the members together. It is to be understood that the edges of the body are secured together independently of the edges of the liner, and vice versa, and thereby the relatively heavy welding operation required for the body will not effect the relatively delicate liner necessarily so intimately associated therewith.

To retain the liner against the body and at the same time prevent the liner from collapsing under the stress set up during the evacuation process aforementioned, forms an important part In accordance with my invention, there is provided at relatively close longitudinally spaced intervals in the liner a plurality of outwardly extending annular corrugations I which preferably seat in correspondingly formed corrugations I provided in the sides of the-body I. The corrugations I of the liner, as will be seen from the drawing, are relatively large and deep and as a result they not only aiiord general stability to the liner but render the sides of the latter able to withstand collapse in spite of high differentials in pressure that may exist within and without the container or within and without the liner. As will be clear from Figure 1, there is preferably provided on the body I in addition to the corrugations I, circumferential corrugations I! which are located at opposite sides of the center of the body andserve as a means of supporting the drum in rolling. The corrugations I! are even larger and deeper than the corrugations I and are engaged on the inner side by corrugations II of the liner, thereby further materially strengthening the liner against injury or deformation when subjected to the forces tending to induce -collapse. It is also to be noted that.in the design illustrated, a corrugation I is interposed between the rolling corrugations and that another corrugation I is interposed between each rollingcorrugation and the reinforced ends of the liner, thus effectively distributing the collapse resisting areas of the liner over the entire length thereof.

l br closing the bottom opening in the drum I provide a lower head II which is connected to the lower edges of the body and liner by means of a double seam joint II. It will be evident that in order to obtain the necessary protection against corrosion in the drum, the bottom as well as the sides thereof must have a non-corrosive surface to present to the interior of the drum. Heretofore in the use of non-corrosive lined drums, the bottom as well as the sides were provided with separate liners. Such an arrangement, however, proved unsatisfactory for the reason that the inclusion in the Joint between the bottom and sides of the drum,'of both liners in side by side relation prevented the use of a simple joint such as here illustrated. In fact, unless an unproportionately large and expensive'type of joint was used, one or both edges of the liner would invariably quickly become withdrawn from the Joint before or soon after the vacuum in the drum reached any appreciable value. To overcome this difliculty I use in combination with the liner provided body of the drum, a bottom head of the type formedpf a single thickness of metal. "Ihe head used here is formed of black steel with a plating or coating ll of non-corrosive steel integrally associated therewith and provided on the side of the head exposed to the interior of the drum. It will be evident that with this form of head there will be but one separate liner in the joint between the head and body and therefore both head and body will combine to effectively retain the single liner between them. A most effective combination is thus aflorded.

Preferably an upper head II is provided of a type similar to the lower head ll so as to facilitate the proper Joining of the two.

I claim:

1. In a non-corrosive metal container of the character described, a body member of relatively heavy sheet material, an end member of relatively heavy sheet material, a liner of a relatively thin sheet non-corrosive material formed separate of and covering the inner side of one of said members. the other-of said members being metallic and non-corrosive on its entire inner surface, the edges of said members being rolled together to form a double seamed Joint, the aforesaid lining extending into the joint and contacting as a packing the inner surface of each of the aforesaid two members within the joint.

2. In a non-corrosive metal container of the character described, a cylindrical body member of relatively heavy sheet material, an end member of relatively heavy sheet material, a liner of a relatively thin sheet non-corrosive material formed separate of and covering the inner side of said body member, the end member being metallic and non-corrosive on its entire inner surface, the edges of said members being rolled together to form a double seamed joint, the aforesaid lining extending into the joint and contacting as a packing the inner surface of each of the aforesaid two members within the joint.
