To all whom it may concern:-

Be it known that I, CHARLES FRANCIS JENKINS, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and .useful Improvements in Foldin Boxes, of which the following is a specification, reference-being had therein to the accompanying drawing. 7

The general object of this invention is to produce a box structure having all its parts connected and adapted to lie flat when not desired for use, and to be folded into the form of a closed box, preferably self-sealing, when desired.

The invention, although not limited, is more especially intended for producing paper boxes for small articles or merchandise 'or materials usually delivered in cartons,

where hermetic scaling is not essential, and where it is .desirable to have somewhat greater strength and durability under rough handling than are found'in ordinary cartons, and where at the same time convenience in use and lowcost are indispensable' In the accompanying drawings: Figure 1. shows the entire structure in fiat form. Fig. 2 is a section on the line 22, Fig. 1. Fig. 3 is an end view of the closed box. 'Fig. t

i is a section on the line 4-4=, Fig. 3. Fig. 5

is a front elevation of the closed box. Fig. 6 is a perspective view showing a modification of the flat sheet. Fig. 7 is a section between the ribs of Fig. 6. Fig. 8 is a perspective View of a modification of the corrugated member shown in Fig. 6.

In these views, A represents a sheet of heavy paper or paper board after .it is formed by creasing it transversely at A, A to divide it'into rectangular sections A A A A A, which are to serve as the sealing flap, the top, theside, the bottom, and another side, respectively, of the complete box, and further formed by embossing each section, except the flap, to form parallel, slightly separated ribs, B, B near and parallel to the parallel free margins of the several sections. The ribs are preferably beveled at each end so that when adjacent sections are so folded as to be perpendicular to each other, the beveled ends of the ribs are pressed together. In order that the ribs may be 'held against spreading or flattening, and to form strong hinges between the sections, as well as to bind the box at each end and 1mprove its appearance, textile tapes or strlps F of tough paper wide enough to cover the grooves, are cemented to the margins of the sheet A.

The ends of the box are plates 0, each of which is secured to one of the sections by a hmglng strip D in such manner that the end may lie fiat upon the section as shown in Fig. l, or may be swung to perpendicular position and thereby have its hinged edge seated in the space or groove between the adjacent ribs. In this latter position each end lies in the plane of the corresponding grooves in the other sections, and when the latter are properly folded the remaining margins of the end are seated and securely held in the corresponding grooves, the seating being aided by the rounded form of the ribs. The goods to be inclosed may be placed in the, box before the cover is folded down, and the cover being closed, the package may be sealed by moistening and pressing down the flap, WhlCh is provided with gum at E.

In Fig. 6 I have shown the modification of omitting the tapes or strips and the embossing of the sheet A and securing to the face of the sheet strips G of paper or equally rigid material provided with ribs G analogous to those of the other figures and similarl located with respect to the margins of the sheet, the latter in this case being a plane sheet simply scored or grooved along the folding lines. If the strip G be of paper, it is conveniently secured to the sheet by paste, but if it be of metal it may be formed with tongues or spurs H or I, as shown in Figs. 7 and 8.

What I claim is:

l. A folding box body consisting of a paper sheet weakened along parallel bending lines and having near each margin transverse to said lines two slightly separated, parallel embossed ribs adapted to receive and hold,

between them, box end pieces, when the sheet is folded to box form.

2. A folding box having a body sheetend to end 'of the same, and spanning, re- I gle paper sheet weakened along parallel bending lines and embossed to form near each margin transverse'to said lines two parallel end-retaining ribs each notched at the folding lines, substantially as set forth.-

4. A box body sheet having on one face near each of two opposite margins an endreceiving channel and u on the corresponding parts of its opposite Face permanently attached bands transversely bridgin the entire channel formation, substantia ly as set forth. I V

In testimony whereof I afiix my signature in presence of two witnesses.

JAMES L. CRAWFORD, WALLACE GREENE.
