JOHN L. CHRISTENSEN, or German, tumors.-

FIBER-BO i 11 BOX.

To all whom it may concern:

Be it known that I, J OHN L. CHRISTENSEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Fiber-Board Box, of which the following is a specification.

The invention relates to boxes -.or receptacles such as are commonly employed in retail selling establishments as containers for articles of merchandise. One type of such receptacles is generally known as suitboxes but the invention pertains to all boxes of this general character irrespective of the particular use to which they may be putand also, in its broad aspects, irrespective of size.

Boxes of this general class now in general use are usually constructed in two separate sections and are supplied to the user in the form of fiat blanksso as to occupy a minimum amount of space in shipment and in storage, and hence must be assembled by the user. My invention is directedto a boxer receptacle which is capable of being made from a single sheet of fiber board or other suitable material and which while assembled at the factory is nevertheless capable of being folded or knocked down so as to permit of its shipment and storage in a flat form, occupying a relatively small amount of space more than that occupied by the flat blanks.

The primary object of the present invention is to provide a box of this character panying drawings forming part hereof wherein I have illustrated a single embodiment of the invention. I contemplate, however, that various changes in the form, construction and arrangement of the parts may be made by those skilled in the art but without departing from the spirit and scope of my invention as expressed in the appended claims.

Specification of Letters Patent.

Patented July 11, 1922.

This application filed may 5, 1922.

Referring now to the drawings, Figure 1 is a perspective view of my improved box inits assembled form. Fig. 2 is a top plan view of the blank folded into the form which it occupies when it leaves the factory.

Fig. 3'is a plan view ofthe blank from which the box is formed andhaving secured thereto a reinforcing stripfor one wide wall of the box. Fig. 4 is a plan view of a portion of the blank used in the construction of a modified form of corner connecting means. Fig. 4 is a fragmentary perspective view of such connecting means. Fig. 5 is a fragmentary perspective view illustrating the method of folding the blank midway between its ends in the operation of closing the box. Figs. 6 and 7 are erspective views showin the positions which the parts occupy at di 1ferent stages in the operationof closing the The box in its preferred form comprises an upper or top section A and a lower or bottom section B formed from a single sheet of material such as fiber board and each comprising a main wall, opposite end walls, an outer side wall and an intermediate or common side wall. Thus the upper section comprises a main wall 11, end walls 12, and

an outer side wall 13. An intermediate side wall 14, which it will be observed, is common to both sections, constitutes a hinge between the two sections. The corresponding end walls 8 and 12 of the two sections are preferably connected together by rectangular intermediate portions 15 which are notched at their free edges as at 16, so as to permit of arelative substantiallyindependent swinging movement of these walls with respect to each other whereby to facilitate the operation of swinging the sections into interfitting relation, as hereinafter more fully set forth. To permit the box to be folded into its flat or knocked-down form, the opposite outer side walls are scored diagonally adjacent their opposite ends as shown at 17 and 17.

The preferred manner of forming the various walls of the box as above set forth and as herein shown, consists in cutting and scoring a rectangular blank along longitudin'al transverse and diagonal lines, as shown in Fig. 3, to form the various portions of the blank including two rectangular main portions 8 and 11; opposite end portions 9'and 12; outer side portions and 13; and an intermediate portion 11. Between the corresponding end portions 9 and 12" of the two Sections are rectangular portions 15, and at the corners of the blank are corner portions or flaps 10 and 12", respectively.

In connecting the opposite end portions 9 of the upper section with the outer side portions 10, the latter in the construction shownin Figs. 1 to 3, 6 and 7, is cut at its opposite ends, preferably on diagonal lines 19, and is: severed from the adjacent corner portions along longitudinal lines 20. By reason of the. severance of the corner ,por-

, tionsfromthe portion 10, when the end portions 9 and the side portion 10' are the ends of the corner portions lie inside the opposite ends of the side portion.- The specific construction which is thus .simpllfies the assembling operation.

provided Upon the free end 'of the outer side portion 10, there is preferably provided a flap 21 (Fig. 1) which is of a length equal to the length of said side portion at its upper edge and which is capable of being folded upon" a transverse score 22 inwardly and downwardly upon the inner face of the side portion 10 to form a reinforcing or stiffening strip 21 (Figs. 2 and 3). Preferably thls flap folds over the overlapping. corner portions 10. In providing for the flap 21, the blank is obviously made of sufliciently greater length and preferably in so doing the corner portions 1O are also made of a correspondingly greater length, and it will be observed that by reason of such increased length of the corner portions when the latter are swung into perpendicular relation to the main portion 8 and the end portions ,9, they serve to reinforce or brace additionally the outerside wall 10 against vertical strains.

The several portions of the blank are secured in their folded relative perpendicular position with .the corner portions flat against.

the inner face of the outer side portion 10 at the opposite ends of the latter and with the flap E21 folded inwardly upon the-inner face of the portion 10, in any suitable way. Preferably a suitable number of staples 23 are em loyed for this purpose, but it willbe obv ous that the parts may be secured together in any other suitable or preferred manner, as by means of a suitable adhesive.

It may be seen that the diagonal fold at 17 in the outer side wall 10 of the box is facilitated by a diagonal score 24 in each of the corner portions 10 and by the shape of the ends of the side portion 13*- cut on the lines 19 approximately coinciding with the. scores 24 in the corner flaps when the latter are secured in position upon the side portion 10.

In forming the lower section B of the box, the corner portions 12 are severed from the adjacent ends of the end portions 12 to permit the end portions and the outer side portion 13 to be swung into perpendicularrelation with reference to the main portion 11. Preferably the corner portions 12 in this instance engage the outer faces of the end portions 12 and are secured in position by suitable means, such as staples 23 v This arrangement of the corner portions 12 enables the twosections of the box to be assembled more readily than would be possible if they were secured to the side wall portion 13*, since as hereinafter. set forth, the end walls of the lower section are swung into an inwardly inclined position in the assembling operation, out of alinement with the endwalls of the upper section. Moreover, the double thickness provided by the overlapping of the corner portions upon the outer side wall, in the case of the upper section, and upon the opposlte end walls in "the case of the'lower section, adds strength vided with diagonalscores 24 near the oppositeends thereof. v

In Figs. 4 and 4? I have shown another methodof connecting the outer side walls .with the opposite end'walls: This method,

while somewhat more expensive from a manufacturing standpolnt, is preferable where a more rugged construction 1s desired. In the present instance I have shown this method of fastening the end and sidewalls, in connection with the upper section only, although it will be apparent that such Walls of the lower section may be similarly connected. 1 V

The means which,I employ in this form of the box comprises rectangular corner portions 10 which are formed integrally with both the side and end walls to be connected.

These corner portions are .swung bodily into an upright perpendicular relation to the end walls and to the main wall, against the outer sidewall and secured thereto. .To this end the outer side wall is scored diagonally near each end, as at 17, as well as lon itudinally as at 20,and in the operation 0 swinging the corner portion into such perpendicular relation, it flexes with reference to the side wallalong the longitudinal line 20 and the side wall doubles upon itself along the diagonal line 17 (Fig. 1). The corner portions may be secured in position in any suitable manner, as by means of staples 23; and they are scored diagonally at 24 as in the construction first described to enable the side walls to bend outwardly as the end walls swing inwardly flat upon the main wall.

It will be observed that when the corner portions are thus swung bodily into upright position, they constitute stays which serve to resist vertical strains and thus impart strength to the box.

The intermediate side wall 14 of the box, it will be observed would normally be only of single ply as compared with the double ply construction formed by the overlapping walls 10 and 13 when the box is closed. For the purpose of strengthening this intermediate wall, there may be secured upon its inner side a reinforcing stri 25 of a length approximately equal to the length of the box. This strip is of a width slightly less than the width of the intermediate wall so as not to restrict or interfere with the swinging movements of the sections A and B into interfitting relation. The strip may be secured in position as by means of adhesive or in any other preferred manner.

he operation of swinging the two sections of the box into interfitting or closed relation from the flat form shown in Fig.

2, is substantially. as follows: The operator grasps with one hand the outer side wall 10 of the upper section A, swinging it upwardly toward a perpendicular position relative to the main wall 8 while swinging the top section bodily upwardly toward the bottom section. As the side wall 10 is thus swung upwardly the connected end walls 9 are forced outwardly, (Fig. 6) and it may be observed that this latter operation is facilitated and insured by reason of the reinforcement of the side wall 10 by means of the strip 21. Through the operation of such reinforcing strip, the portion of the. end wall between the diagonal folds 17 remains approximately rigid and straight. Consequently as it swings into upright position, the ends of the wall 10 beyond the folds 17 are carried into alinement, and the latter acting upon'the adjacent connected end walls 9 force them into upright or perpendicular position with respect to the main wall.

At the same time, the operator places his free hand upon the outer side wall 13 of the lower section 8 and presses ('lownwardlp thereon. This tends to restrain the opposite end walls from swinging upwardly notwithstanding the upward swinging movement of the end walls 9 of the upper section. Such relative movement between the end walls 12 of the bottom section and the end walls 9 of the upper section, is permitted by reason of the presence of the notches 16 in the rectangular connecting portions 15 between the end Walls 9 and 12 of the two sections, as above set forth. N ow, as the upper section A is brought forwardly and downwardly over the bottom section B, the end walls 9 occupy a position into or slightly beyond' perpendicular relation to the main wall 8 of the top section, and on the other hand the end walls 12 occupy an inwardly inclined relation with respect to the inain wall 11 of the lower section. It will be evident, there fore, that the. end walls 9 and 12 are caused to assume, in a semi-automatic manner. their proper relation with respect to each other to insure'that they will not interfere as the two sections are brought together with the bottom section within the top section.

To permit the end walls 9 and 12 thus to be swung into overlapping relation, the connecting rectangular portions 15 in addition to having the notches 16 therein, are scored diagonally along lines 26 approximately in continuation of the edges of the notches. As shown in Fig. 5, as the end walls 9 and 12 are brought together. opposite triangular portions overlap forming a substantially closed joint.

As the top section in its forward and downward movement approaches the bottom section, the lower edges of the end walls 9 engage with the outer side faces of the inclined end walls 12. and the lower edge of the outer side wall 10 rests upon the upper edge of the outer side wall 13 at the opposite ends thereof. As shown in Fig. 7, these ends are inclined upwardly and inwardly from the upper ends of the diagonal scores 17 and the extreme outer corners of the lower section by reason of such inclination of the ends of the outer side wall and of the inclination of the opposite end walls, are positioned well within the upper section. In the final operation, therefore, of closing the box, it is only necessary for th'e'operator to force the upper edge of the outer side wall 13 of the lower section inwardly from the position shown in Fig. -7 until it clears the lower edge of the outer side wall 10 of the upper section. Thereupon the two sections Ina be forced into telescoping relation.

f desired. the box may now be tied by a single strand 26 around the central portion thereof to maintain the two sections in closed relation. and it will he observed that the reinforcement provided by the flap 21 upon the outer side wall 10 of the upper section insures that the portions of such outer wall upon opposite sides of the cord will not bulge but will be held firmly in position against the adjacent inner wall 13; also that such outer wall will not become torn or broken by reason of the presence of the tie,

as frequently happens in boxes of this general class.

I obtain a distinct advantage in the arrangement of the corner portions so that in the case of the upper section they form part of the outer side wall, and in the case of the lower section they are made rigid with the end walls. It facilitates substantially the operation of assembling the two sections, and imparts strength thereto. In the case of the construction shown in Figs. 4 and 4, it provides vertical stays both upon the sides and the ends of the box.

It will be apparent that the box thus provided is of a very advantageouscharacter. Its simplicity enables its manufacture on an economical basis; it lends itself readily to shipment and storage in large quantities and at a relatively low cost; the entire operation of assembling the box from its flat knocked-down form into closed condition, requires only a few seconds; and when the box is thus completely closed, it presents a neat appearance and is of substantial strength capable of resisting heavy vertical strains.

In compliance with the statute, I have illustrated and described my invention herein as embodied in a box of the preferred form. Certain details of this box are'the invention of one Albert Dreyfus and myself, jointly, and claims directed to such features are contained in a copending application Serial No. 553,246 filed April 15, 1922.
