FOLDING BOX Application filed. January 26, 1932. Serial No. 588,893.

This invention relates to foldable or collapsible card board boxes and has for one of its objects the provision of a box of this character possessing great strength when in use.

Another object 0; the invention is to produce a box of this nature, comprising a bottom section, side and end sections, end section protecting flaps, top flanges on the said flaps, and top or lid sections, all made of a single sheet of card board suitably scored so that the box, when not in use may be kept in flat or unfolded position, and thus save a great deal of space.

A further object of the invention is to provide such a box with releasable joining means at the end sections and with eficient releasable locking means to maintain the protecting flaps, top flanges, and lid sections in closed position when the box is set up and in use.

Another object is to produce a box of the character described in which the maximum simplicity of construction and operation is secured.

Other objects and advantages will appear as the nature of the improvements is better understood, the invention consisting substantially in the novel arrangement and co-relation of parts herein fully described, and illustrated in the accompanying drawings, wherein similar reference characters are used to describe corresponding parts throughout the several views, and then finally pointed out and specifically defined and indicated in the appended claims.

The disclosure made the basis of exemplitying the present inventive concept suggests a practical embodiment thereof, but the invention is not to be restricted to the exact details of this disclosure, and the latter, therefore, is to be understood from an illustrative rather than a restrictive standpoint.

The inventive idea involved is capable of receiving a variety of mechanical expressions, one of which, for the purpose of illustration, is shown in the accompanying drawings, in which- Figure l is a perspective View of my improved box in set up position, showing one of the lid sections in open position.

Figure 2 is a fragment-a1 perspective view of one end of the box with the protecting flap in unfolded position.

Figure 3 is a fragmental top plan View of the end section joining means, and

Figure at is a top plan View of the blank in unfolded position.

Referring now to the drawings in detail 5 indicates the box blank, which comprises a base or bottom section 6, side sections 7 and 8, end forming sections 9, 10, 11 and 12, and section protecting flaps 13 and 14 and lid sections 15 and 16.

The blank 5 is scored along vertical lines 20, 21, 22 and 23 which produce hinges for the base, side-walls and lid sections, and is further scored along horizontal lines 24, 25, 26 and 27, the first two forming hinges for the protective flaps 13 and 14 and the latter two forming hinges for the top flanges 28 and 29 upon which the lid sections 15 and 16 rest when the box is in closed position. v

The blank is severed at 30, 31, 32 and 33 to form the end forming sections 9, 10 and 11 and 12 respectively, the said sectionsbeing cut out at 34, 35, 36 and 37 to provide releasable joining means when the box is set up. Cut outs 38, 39, 40 and 11 are provided 3 at the lines 26 and 27 so that looking tabs 12, 43, 4: 1 and 45 formed at the ends of the sidewalls 15 and 16 may be inserted into the cutouts 38, 39, 40 and 11. The said locking tabs are each provided with inclined locking 55 edges 16 which when the tabs are inserted into their respective openings form eflicient locking means to maintain the lid sections in closed position and prevent same from accidentally opening.

To set up the box, the sections 7 and 8 are first swung up along the lines 21 and 22, then the sections 9, 10, 11 and 12 are swung inwardly to bring the cutouts 3 1 into locking engagement with the cutout 35, and the cutout 36 into similar engagement with the cutout 37. With the box in this position it may be filled with merchandise, after which the protective tabs or flaps 13 and 1 1 are swung 7 up on their hinges 24 and 25 and the flaps 28 and 29 are swung down on their hinges 26 and 27. The lid forming sections are then swung down and the tabs 42, 43, 44 and 45 caused to enter their respective openings 38, 39, 40 and 41. It will be seen that the inclined surfaces 46 on the said tabs will make frictional locking engagement with the inner edges 50 of the openings 38, 39, 40 and 41 and prevent accidental opening of the lid sections 15' and 16.

From the foregoing it Will be seen that I have provided a strong, inexpensive and efficient foldable box, that will withstand a great deal of pressure from the exterior and one in which the lid sections will not open up unless manually operated to do so.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A foldable box made of a single sheet of material, said box comprising a base, side walls, interlocking sections forming end walls, a flap at each end of the box covering the end walls, a horizontally slotted flange On each of the flaps, lid sections extending from the side walls, and a flap at each end of the lid sections, having an inclined edge for lockingly engaging the flange slots.

2. A foldable box made of a single sheet of material, said box comprising a base, side walls, interlocking sections forming end walls, a flap at each end of the box covering the end Walls, a flange horizontally foldable from each of the said flaps, each of the said flan es having a cutout near their line of folding and parallel thereto, a lid hinged along the top of one side wall, and a flap at each end of the lid, the said flaps having an inclined edge for lockingly engaging an end edge of the flange cutouts.

In testimony whereof I hereunto aflix my signature.
