It is thus apparent that 45 This blank comprises the side wall members In the container is provided with a very sturdy douand H having bottom members'l2 and I3 integral ble ply bottom. therewith and top members l4, I5, I 6 and I1. 'Aside from other features hereinafter set forth The end wall members 18 and- I9 have also inteit is apparent that the partition means 40 divides gral therewith the cover'members 20 and 2|, the container into two sections and providesrein- 50 forcement for the walls as well as the container as a whole. Attention is directed to the fact that the members 20, 2|, 24 and 25 in the blank in Fig. l are provided with slightly more material than is required by them to meet their functions in the final form. This extra material designated as 5| and 52, is employed for reinforcing the end walls of the box as well ,as for providing a flange or lifting handle. -Uponinspection of Fig. 5, it will be seen that the strip 5| is folded back against the end face ofthe container and strip 52 is then reversely folded against strip 5|, thereby providing a double ply lip or flange. This material is then securely stapled to the end wall of the box at 53 and 54, where it provides reinforcement. It is notable that the staples 53 and 54 are suitably spaced so that a gap will be provided, therebetween, so that the folded-over material may be expanded for the purpose of forming a handle 55 underneath which the fingers of an individual may be inserted for readily lifting or transporting the container.

These handles 55 are provided as illustrated, across the top of the end walls of the container, and a similar structure similarly formed'is provided along the lower edge of the end walls thereby affording reinforcements designated 56. It is within the contemplation of the improvements to omit these lower portions 56 thereby saving mate rial to the extent that the flaps 24 and 25 will be stamped without the strips 5| and 52, and accordingly will be hinged inwardly directly from the bottom edge of the end wall members. In this event, the handles 55 only will be provided.

In making the handles '55 in the manner illustrated in Fig. 5, these members are integral with their respective end wall and top cover members which provide a strong and sturdy construction and one which is easily assembled. Obviously, the

handles 55 may be supplied from separate mate rial and the cover members 20 and 2| hinged directly to the end wall members. However, as heretofore set forth in making the cover members 20 and 2| oversize so as to provide for this doubled over flange at the end, added reinforcement and protection at the ends and corners is derived.

In using the container, the members l4 to I! may be folded over the sections of the container where they will meet substantially along the longitudinal center. When thus folded over, the slots 42 will expose the pocket or channel 4| provided by the partition means. The top cover members 20 and 2 I, which hinge inwardly from the ends of the container, may now be folded downwardly and the flaps 2712 and 23 tucked into the pocket 4| formed by the partition, wherein they are held by the close fit and engagement in the walls of the pocket. The end flaps 22 and 23 may be stamped in the manner illustrated so as to be interlocked,

if desired, prior to their insertion in the pocket 4 Furthermore, a removable spring clip or paper fastener may be slipped over the ends of the flaps as they are about to be tucked in. Should the chosen material not lend itself to such means, a

card board container of this character, it has been found that covers hinged from the ends permit a sturdier and more rugged construction in the receptacle as a whole.

In providing a rectangular shipping case of this character, no limit need necessarily be placed upon the capacity thereofi For example, the blank may be stamped so that theside and end .wall members are many times the width of the illustrated embodiment, asishown in Fig. 4, the container will be considerably deeper so as to accommodate thirty-six, one

hundred and forty-four or even a larger amount of fragile articles, such as eggs, and the like. The

present improvements lend themselves admirably to this larger size of shipping case, and may be readily lifted by means of integral handles 55 which insure a firm grip on the case since said handles form an integral part thereof and will not therefore work themselves free of the body of the container.

It will be noted that the illustrated embodiment provides a double ply top and bottom so that the articles will be well protected, regardless of which surface of the container happens to be uppermost.

Various modifications within the scope of the present improvements will be apparent to those skilled in the art and may be made without de-. parting from the purview of the invention.

We claim:

l. A box comprising bottom members, side members, end cover members integral therewith, and centrally disposed partition means defining a pocket for receiving depending portions of said cover members, said portions being carried by the edge of said cover and in opposed relation to said side members.

.2. A box comprising bottom members, side members, end cover members integral therewith, and a centrally disposed partition comprising spaced members adapted to receive portions of said cover members, said portions being carried by the edge of said cover and in opposed relation to said side members.

3. A rectangular box folded from a blank comprising side wall members having integral top and bottom members, end wall members having integral cover members, transverse partition means secured to said side members dividing said box into two sections, said partition means comprising spaced wall members defining a channel for receiving portions of said cover members.

4. In an elongated shipping container, cover members hinged at each end thereof, members forming a pocket transversely of the container, and flaps on said cover members adapted to be tucked into and held in said pocket.

whereby upon assembly .5. A shipping container comprising upright side and end wall members, bottom wall members attached to said side and end members and disposed horizontally for providing a bottom for the space enclosed by said side and end wall members, means defining an upstanding pocket between the side wall members of the container, cover members hinged to different upstanding wall members, and the container, said cover members having flaps along the edges remote from their hinges, the cover members extending from their hinges to the position of said pocket means whereby said flaps may be removably nested within said means.

6. A container comprising side, end and bottom walls, means defining an upright pocket extending between said side walls and substantially foldable to provide the top of parallel to saidend walls, cover members hinged to said end walls, said cover members being provided at the edges remote from said end walls with flaps having interlocking means, which, when the covers are in closed position, are interlocked and located within said pocket.

'7. A container comprising side, end and bottom walls, means defining an upright pocket extending between said side walls and substantially parallel to said end walls, cover members hinged to and carried by said end walls, said cover members being provided at the edges remote from said end walls with flaps having interlocking means, which, when the covers are, in closed position, are interlocked and located within said pocket.
