without the employment of extraneous fasproximate edges of the 'walls integralj webs w to be-developed into corner folds. Each the fold m may be cut clear web, w, of the blank is cut away on a trans- Verse diagonal line 25, which connects the outer corners of side-walls, and the web is creased on its axial diagonal or median line m, so as to fold inwardly. Thus, each web when set up constitutes a corner fold f which presents two triangular legs, which I will respectively term the endleg, awn-and the side leg, accordingly-as they adjoin the end wall, 6, and the side wall, 8, of the section. For ease in manipulating the blank, the inner end of through the material as indicated at Z.

It will be apparent that whenthe blank is folded on the crease lines indicated in Fig. 5 (creaseson the exterior of the bottom being indicated in dotted lines and the interior. corner creases edge walls will stand at right angles to the body a, and meet at the corner of the sec-- tion, and the folds 7 will be inturned each.

to stand at approximately. an angle of to both the side and end walls, and with its median crease-line mat an ang to the body a," the point p of. each fold, formed by the juncture of the median line m with the cut edge 25 standing midway of the depth of the edge walls. The section A is similarly constructed, parts thereof being designated by the character applied to see; by the expdnent prime It will be noted that when a single blank is thus folded no means are provided therein to maintain the parts in their work- I ing position or to prevent complete or partial return of the blank members to unfolded ororiginal position. In the formation of a receptacle from two such blanks, however, the inturned corner folds ff and f of opposite sections, are capable o mutual coaction to prevent the sides and ends of either-blank from spreading outwardly, and to hold the sections together in proper funce tional relation. This coaction between the in various ways. For many purposes it is preferablethat the end walls of one section and the side walls of the other'section be positioned exteriorly,

but if desired such assemblage may be made that both the end and side walls of'either section may be exteriorly positioned, the walls of the other member being embraced within them. Briefly, the relation of the walls first mentioned may .be secured by arranging the legs of the corner folds 'of one .sectionto alternate with the legs of the corresponding folds of the other section, or

otherwise stated, by straddling the legs ofeach corner fold of one section across one leg only of the corresponding fold of the opposite section. The arrangement with all of the walls of 'one section standing exte- .riorly may be secured by positioning the corner folds of that section to be embraced L posing corner the contiguous endand In the construction shown 1n Fig. 1, the

sidewalls s of the top section, walls 6 of the bottom section are exteriorly presented, and in Fig. 2 is shown the interrelation of the corner folds roductive of such arrangement. In such View, observed that the bottom fold of bottom section A: straddles only the side leg y of the it will be corner fold of the top section A, while said fold f of the top section straddles the end leg as of the coacting fold f. In practically assembling two blanks in this manner, the desired interrelation may facilelfy be secured by superposing end member 6 o the top section-on end member e of the bottom section, raising the end wall e of said bottom'blank part way toward the vertical position, and then pressing the side walls 8 of the bottom section inwardly toward vertical position. As the sides move inward, pressure 'of the leg m of each affected corner fold f against the opposing leg a2,-serves to draw the side walls s of the top section inward after the side walls of the bottom section A, and to throw the side legs 31 of each of the afl ected folds of the top section A into the angle between the legs a: and y of [the corresponding fold f of the bottom section. Assemblage of the box is then completed by workend in the same general fashion. Obviously, when the remote ends are brought close together, theside walls of the partly-assembled sections all stand in. substantially raised position, and the remaining end members are easily brought together in proper relation by pressingin the end wall e of the bottom section A,'so causing legs'y' of the affected foldsof the top section to press upon the legs y .of the opposing folds of the bottom section, so raising'the end wall 6 of the bottom section with its fold-legs m embraced in the angle between legs w and y of the topsection. It will be obvious that when the box is fully closed and the opposing corner folds f and f are fully interlocked, the free or and t of each fold will substantially coin- .cide with the median line on or m constithe crease-edge of the opposingfold, 7

ds meeting tuting the points 72 and p of the two f0 or coinciding. The resultant few, of which are. capalarge' number of times without deteriorm .tion; absence of projecting partsor tabs ofany description; easy restoration to flat blank form for storage; :and great strength teriorly applied crus'shing strain when assembled. 'Touchin the matterof strength, it will be observe that the interlock ar- -rangement with the plies ofthe folds altercut edge 17' box has many advantageous I to resist internally applied pressure or up nating as described makes it practically impossible for the edge walls to spread at'the corners under internal pressure without rending thematerial apart, because not only do the folds appurtenant to each exterior wall point inwardly behind the. corresponding wall of the other section, at an angle of 45, but, further, each fold appurtenant to an exterior side wall embraces the end leg-of the cooperating fold of the other section.- Furthermore, it will be observed that the interlocked, infolded corners constitute strong trusslike struts or pillars extending in four-fold thickness from the 'top plane to the bottom plane of the box, efie'ctually to resist crushing strains upon the receptacle. I

l/Vhile-I have specifically'described, the arrangement indicated in Figs. 1, 2, and 3, wherein the end walls e of the bottom section A and the side walls 8' of the top. section Aare exteriorly positioned, it will be apparent that such arrangement may be reversed, as diagrammatically illustrated in Fig. 4, the end walls 6' of the top section A and the side walls 8 of the bottom section A being respectively exteriorly positioned.

As a refinement of my invention, particularly advantageous where maximum strength is desired, I find it practical to increase the strength of each corner fold-without the use of any extraneous part by the form of construction illustrated in Figs. 6 to 10. In such embodiment of the invention, I use blanks as shown at A Fig. 6, instead of cutting away the corner web of each blank on its trans. verse diagonal t, I fold the square web w along its diagonal t as shown in the lower right corner of Fig. 6, thereby to double the material to be incorporated into the corner fold F. The blank with its corners thus double may be employed in any of the arrangements shown in Figs. 3, 4, and 5, the arrangement indicated in Figs. 7 to 10 corresponding with that shown in Figs. 2 and 3 of the views heretofore described. Like parts are indicated by the same characters used in Figs. 1 to 5, but with the exponent 2;

The susceptibility of my invention to em bodiment in different forms is herein shown, and in any of its embodiments illustrated, it provides a cheap, strong, durable, and easily manipulated construction, but it will be 'uncorner fold derstood that by such showing of-several embodiments of my invention, I do not intend'to limit its application to the few specific forms shown, but that to the contrary, many other changes might be made in the embodiment of the invention without departure from its spirit and within the scope of the appended claims.

WVhat I claim is:

l. A paper box comprising top and bottom sections providing at corresponding cor ners inturned interengaging corner folds, each fold having its two legs straddling one leg of the corresponding fold of the other section.

2. A paper box consisting of a top section and a bottom section, each having in an integral structure a body, .an end wall, a side wall, and a corner web inturned to constitute a corner fold having its fold edge lying in an axial diagonal of the web, and its free edge not extending beyond the transverse diagonalof said web, said corner. folds of opposite sections interengaging with the folded edge of each fold straddling the free edge of one leg of the opposite fold.

-3. A paper box consisting of a top-section and a bottom section, each having in an'integral structure a body, wall, and a square corner web folded upon itself on its transverse diagonal and folded inwardly on its axial diagonal to form a presenting opposing triangular legs each of double thickness, each said corner fold of a box section interengaging with the opposite corner fold of the other box section to straddle one leg of said opposite corner fold and to have one of its legs strad dled by said opposite corner fold.

4. A paper box consisting of a top section and a bottom section, each having in an integral structure a body, an end wall, a side wall, and a corner web, the corner webs of the two sections of the boxbeing duplicates, each constructed and arranged to straddle one leg of the corresponding web of the op-v posite section.

In testimony whereof I hereunto set my hand in the presence of two witnesses.
