Application June 29, 1933, Serial No. 678,292 4 Claims. (0]. zoo-4am Our invention relates to an improved container as a new article of manufacture, and refers more specifically to a container in which inflammable objects may be stored or transported without appreciable fire hazard.

An important field of use for our invention, and one for which it was primarily designed, is the shipment and storage of cinematographic films. It is well known that such; films are more or less inflammable and that, in consequence, regulations governing the storage and transportation of such films require that they.be enclosed in containers as nearly fireproof as possible. The

containers heretofore employed for this purpose These V drums are. fairly heavy and expensive. Inasmuch are most usually metal drums or cases.

as great numbers of such films are shipped by air transportation and by parcel post for long distances, the weight of the container is a most important factor and any container which will combine substantial safety against fire danger with lightness of weight and cheapness of manufacture presents pronounced advantages over metal containers. I

With the foregoing in mind, the principal object of our invention is to provide a shipping or storage container, mainly although not exclusively for cinematographic films, which is light in weight and substantially fireproof in the sense of being non-inflammable. We accomplish this object by forming the container of fireproofed corrugated board or paper, and if desired the container may contain a lining of asbestos or asbestos lined paper.

The container of our invention may take any form suitable for the purpose'to be served, and by way of illustrating the application of the in: vention we have shown it embodied in a box or i carton for the storage and. shipment ofcinematographic films. 1

In the accompanying drawing, Fig. 1 is a perspective view of such carton with the top flaps open and the contents disclosed; Fig. 2 is a section'on the line 2--2 of Fig. 1, and Fig. 3 is a section of a fragment of the corrugated board of which the carton is made, an asbestos lining being shown in this figure.

The body of the carton is designated generally by the numeral l0 and is provided at the top and bottom with closure flaps H, I2, l3 and H. A permanent bottom closure is formed by applying non-inflammable adhesive to the outer and inner faces of certain of the flaps and then pressing such flaps together in overlapped. or superimposed condition until firm interconnection is established.

carton body HI and preferably held therein by non-inflammable adhesive. Open ends of the boxes I are adjacent the openable top of the carton so that the drums of film I6, within the boxes l5, are easily accessible when the carton top is open.- An intermediate portion of the edge of the wall at the open end of each box is notched as at l1,'the several notches being alined or registered to present a clearance for the fingers of a hand to engage thedrums I6 and withdraw them selectively from the carton.

As shown in Fig. 3, the corrugated board is preferably double walled, consisting of the corrugations ID, the intermediate sheet l0 and the face sheet l0. The car-ton body I I] with the flaps at both ends thereof is made of fireproofed corrugated board and the individual boxes l5 are also desirably, although they need not necessarily be,

made-of fireproofed corrugated board. A face sheet Ill may, if desired, be asbestos protected as shown at lll Although the actual step of fireproofing the.

corrugated board is not a part of our invention, we prefer to employ a board which has been fire- A proofed by the addition of borax and boric acid, or ammonium sulfate to the. pulp from which the board is manufactured, or applied to the paper during or after manufacture.

We have ascertainedby exhaustive tests that a container of fireproofed corrugated board, embodying our invention, complies with all the requirements laid down by the competent authorities for the shipment and storage of inflammable substances; consequently our invention provides a container much lighter in weight and moreeconomical of production and use than prior art containers for similar purposes.
