Nov- 25,1941 H. G. BERGSTROM 'FOLDING BOX WITH SLOT'IED DIVIDER MEMBERS Filed Oct. 16, 1945 HAROLD G. BERGSTROM Patented Nov. 25, 1947 FOLDING BOX wrrn SLOTTED mvnmn MEMBE Harold G. Bergstrom, New Rochelle, N. Application October 16, 1945, Serial No. 622,546

This invention relates to folding boxes and more particularly to a box which is fitted for use as a filing and shipping container for fiat articles such as flat films, transparency and microscope slides. photoprints, filing cards, fabric samples, and so on.

It is an object of this invention to provide a box formed by folding a single sheet of paper, carton, plastic film, thin sheet metal or other suitable material and presenting coacting rows of slotted holdersfor the insertion, in corresponding slots, of the flat articles to be stored and/or shipped therein.

It is another object of the invention to provide a folding box of the character described, in which the slotted sections are securely arranged in spaced relation to the side walls of the box and in turn serve to reinforce these walls.

With these and other objects in view I will now describe the invention more in detail, having reference to the drawing aflixed to this specification and forming part thereof, in which an embodiment of the invention is illustrated diagrammatically by way of example.

In the drawing:

Fig. 1 is a perspective view of the sheet of foldable material which, when folded, constitutes the box proper.

Fig. 2 is asimilar view of this sheet in partly folded condition.

Fig. 3 is a perspective view of the completely folded box partly projecting from a prismatic slide-on cover.

Fig. 4 is a perspective cross section, drawn on a larger scale, along the line IVIV in Fig. 3.

Fig. 5 is a vertical cross-section.

Referring to the drawing and first to Fig. 1, the main, substantially square part of the sheet to be folded into a box is subdivided by four parallel creases I, 2, 3, 4 into five oblong sections. The middle section 5 is to form the bottom, the two adjoining sections 6 and 1 which may be somewhat narrower than section 5, will form the side walls. The outer sections 8 and 9, are wider than the wall sections, and each of them is traversed by a longitudinal middle crease [0 which allows its section to be folded in such manner that on its free longitudinal edge ll being made to rest, when the respective side wall is set up at right angles to the bottom, in the respective crease I 1 Claim. (01. 229-28) or 4, the two halves of the outer section will form the sides of an obtuse triangular prism with the section B or I as bottom. The two outer sections 8 and 9 are subdivided by cuts l2 extending across and at right angles to their middle creases into rows of juxtaposed strips l3, it. These strips are folded alternately in opposite directions, as shown in Fig. 5, like the warp threads on a loom, the bends of the strips l4 abutting against the side wall 6 or 'I and reinforcing it, while at the same time leaving open slots I5 into which films or cards 16 may be inserted to be held therein in vertical position, as indicated at IS in Fig. 5.

The end wall forming sections are shown in Figs. 1 and 2. At each end of the main part of the sheet are provided three short sections, the outer ones I! and I8 being about squares and extending in line with the side wall sections 8 and I, while the middle ones are composed of a part I 9 as wide as the bottom 5 and as high as the side walls, and two trapezium-shaped parts 20, 2| joined at their shorter sides, their combined heights exceeding that of the part l9. Creases 22, 23 are formed between the parts I9, 20 and 2 I. The ends of the box are closed by first folding the sections l1, l8 at right angles to the side walls, then folding the side walls at right angles to the bottom whereby the two sections I1 and I8 at each end are made to overlap, being held in this position by the turning up of the bottom end parts iii. If the parts 20, 2| are then folded into the same position as the slotted outer sections 8 and 9, their joint 23 will project into the box and their free edge 24 will rest in the crease 25 between the bottom 5 and the part IS. The sections ll, l8 and l 9 now form a closed projecting wall of triangular cross-section.

When completely folded, the box is best protected, for storage and shipping, by a slide-on cover such as shown in Fig. 3.

Obviously the proportional sizes of the different parts constituting the new folding box may differ materially from those shown by way of example in the drawing.

I wish it to be understood that I do not desire to be limited to the details above described and illustrated in the drawing, for obvious modifications will occur to a person skilled in the art.

I claim:

A box comprising a bottom and four side-walls 3 extendlng'at right angles to said bottom, strips of pliable material being fixed by a longitudinal edge to the free longitudinal edge of each wall of a pair of parallel side-walls, said strips being of materially greater width than said walls, a crease being formed near their longitudinal middle line, their free edges extending into the corners between the said walls and the bottom, and parallel cuts formed in each strip extending at right angles to, and across said crease, some or these strip sections between such cuts being folded back towards the side wall. v
