FOLDING BOX.

Specification of Letters Patent.

Patented Sept. 19, 1911.

To all whom it may concern Be it known that I, JOHN G. REBER, a citizen of the United States, residing at Chicago, in the county of 'Cook and State of Illinois, have invented certain new and useful Improvements in Folding Boxes, of which the following is a specification.

My invention relates to folding boxes made of paper board or thelike, and the general object thereof is to provide a simple and efficient box of this character, possessing features of advantage and utility which will be apparent from the description hereinafter given. 7

My present invention is an improvement upon that described and claimed in an application for patent filed by me on March 19, 1906, Serial No. 306,854, in which form of box I employed flexible strips of wood or the like at the top edges of two of the opposite sides for the purpose of not only strengthening such sides but also of holding the box in its erect or assembled condition. My present invention pertains more particularly to the means for and manner of holding or securing these strips to the box and also relates to certain features of box construction to cooperate with said strips.

In the drawings, Figure 1 is a plan View of a blank from which the particular box herein illustrated, known as a suit box, is formed; Fig. 2 a perspective of one corner of the box showing. method of folding; Fig. 3 an enlarged sectional elevation on the line 3-3 of Fig. 4; Fig. 4 a perspective of the box in its assembled or erect form; Figf 5 a perspective of one end of the box with its flexible strip removed; Fig. 6 a section on the line 66 of Fig. 3; Fig. 7 an elevation of a portion of one end of the box; Fig. 8 a plan view of one end of a blank of modified form; Fig. 9 a perspective of one end of abox made from themodified form of blank illustrated in Fig. 8; Fig. 10 a section on the line l0-10 of F ig. 9; and Fig. 11a perspective on a somewhat larger scale than in Fig. 9 illustrating one end of suchmodified form of box but with its flexible strip-removed.

My invention is applicable to different forms and types of boxes, such as hat boxes, suit boxes and the like and, although in the present instance I have shown my invention in connection with the particular form or type of box known as a suit box, yet it will be understood that I do not intend to limit myself to such special form of box,

particularly as the proportions of the box may be obviously changed to produce a great variety of boxes intended for different special purposes.

Referring'to the present embodiment of my invention; which is in the form of the well-known suit box, the blank from which such box is formed comprises a rectangular bottom A, two opposite side walls B, two end walls C 0, all of which are hinged to the bottom A, and also corner folds I) and E. These corner folds are substantially triangular, the same being arranged in four pairs at the four corners of the box, of

which the folds D are hinged to the ends 1 walls C, and as a matter of convenience in description, I prefer to call theformer the side walls and the latter the end walls, al though they all may be considered side walls.

To the outer edges of the end walls G of the box are hinged extensions or flaps which are hinged upon each other and adapted to be folded over upon or wrapped around strips F of flexible material, such as thin strips of wood or wood veneer, such folding being done in the particular manner hereinafter explained. As shown the innermost flaps or extensions 0 are continuous or entire but by preference, thc'outermost ones only of these flaps are severed, the same being transversely out along the two lines 0 so as to form the end portions 0 and the central or intermediate portions or extensions 0?. As shown in Fig. 1, the lines o are oblique for the purpose of cutting the outer corners of the flaps a on a bias, thereby forming on the inner adjacent corners of the extensionsc the tongues or points having the'ofli'c'e or function hereinafter ex- 7 plained.

' In pra'etlce, the strips F which are flexible and afford a torsional strain. or pressure when twisted, are folded or wrapped within the extensions or flaps, the extensions 0 being tucked behind the strips with their outer faces lying against the inner faces of the end walls of the box. The intermediate or short flaps 0 are merely folded over the strips and positioned flat against the inner faces of the end walls of the box as shown in Fig. 4., instead of being folded underneath and around. the strips, as is the case with the .extensions 0. The intermediate extensions are secured to the end walls of the box in any suitable manner, as for. -instance by means of a staple G passing through such end walls and through the extensions 0 as clearly indicated in Fig. 4. b v

The box as thus far described represents the construction as produced at the factory,

the box being shipped. to the customer or by the customer or user to put the box to use the same is brought to erect form by merely raising the end walls and folding them together toward each other and then lifting and slightly twisting the ends of thestrips in order to permit such'strips to slip over the upper edges of the corner folds and to take their position on the inner sides or faces thereof. In. this lifting of the strips, the latter are twisted, but owing to the fact that they are .flexible and resilient, the same spring back into normal condition after they have been slipped over the upper edges of the corner folds to thereby lock and maintain the box in erect form.

By dividing the outermost flaps or extensions in the manner described the. strips are held in proper relationship with the end Walls by means of theintermediate or central extensions, but at the same time are per- I mitted to properly yield or twist even beyond their middle portions, in the operation of applying them over the corner folds. It will be understood that the tongues 0* extend underneath the strips within the lines of the central or intermediate extensions a with the result that the extensions thus wrapped around the strips are locked in place so that in the lifting or twisting'of the strips it is impossible todetach such extensions from the strips. In this simple manner the extensions and strips are held together and at the same time the cutting of the free corners does not detract from the efliciency of-the' central extensions but ratherimp'roves the'appearance thereof. The object of the notches (l in the corner folds D is for the purpose of assembling and locking the box in erect condition without requiring the strips to be raised as far back as would otherwise be necessary. It will be understeod that the score lines running longitudinally through the central extensions 0 are not'essential but are incidental to the formation .of the score lines which divide the extensions c 0' and on which they are hinged.

My invention may be applied to boxes made from different forms'of blanks without departing from the spirit of my invention. For instance, while in the box just described both the corner folds D and E were hinged to the walls of the box, yet if desired only onemember of each pair of corner folds maybe so hinged. Such a modified form of box is illustrated in Figs. 8 to 11, wherein the parts similar to those illustrated in the other figures are provided with the same letters of reference but primed.

As illustrated in Fig. 8 the blank comprises the bottom A,'the side walls B B, and the end walls C, of which only one is shown. Each corner of the box is provided with the corner folds D E hinged on the diagonal line 6, of which the corner folds D are hinged to the ends of the side walls B. However, inthis particular instance the corner folds E. are not hinged to the end walls but are separated therefrom by the cute. Moreover, in this modified form'the corner folds E, instead of being triangular as in the form hereinbefore described, are'trapezoidal in shape, the same being extended as far as the outer line of the extensions of the end walls. As in the form first described, this modified form is providedwith

end wall extensions

0, 0, but in this particular instance both extensions are out and moreover on straight lines 0', there by forming the end portlons or extensions proper marked 0 0 and the central or intermediate portions or extensions =0 In practice the corner folds E are brou ht inwardly withtheir outer faces resting at upon the inner faces of the end walls and after the strips have been applied to the flaps or extensions in the same manner as previously described, the corner folds E are secured tothe end walls in suitable'manner and in the present instance the parts are so secured by the same staples or fasteners H which are'employed to fasten the central extensions c in place, all as clearly indicated in Fig. 9. It is obvious that the central extensions 0 need not be divided by the longitudinal score line which is present as an incident in actual practice to the formation of the score line on which the

extensions

0, 0 are hinged. Likewise the folds E have two the corner folds E. The box is set up or assembled'to its erect form in the same manner as the first form of box described.

It will be understood that where my invention is applied to a suit box, where the top and bottom portions are similar, another box portion of the same character is provided but difl'ering slightly in size so that one portion may be readily telescoped into form of suit boxes. Also where my invention is applied to another form of boxsuch as a hat box any suitable lid or cover, of the same structure as the body portion or otherwise, may be provided.

I claim:

l. A -folding box comprising a bottom, walls hinged thereto, corner folds connected with two opposite walls and foldable into the box, flexible strips for the upper edges of the end walls, and separate extensions on each of said end walls, which extensions are wrapped around the strips; substantially as described.

2. A foldin box comprisin a bottom walls hinged t ereto, corner fol s connected with two opposite walls and foldable-into the box, flexlble strips for the upper edges of the end walls, and extensions on said end walls, which extensions are wrapped around the strips and extendedinwardly on their adjacent edges; substantially as-described.

3. A folding box comprising a bottom,

walls hinged thereto, corner folds connected with two opposite walls and foldable into the box, flexible strips for the upperedges of the end walls, and extensions on said end walls, the outermost one of which extensions is transversely cut in two places, forming two end portions which are wrapped around the strip and an intermediate port-ion which extends over such strip and is secured to its end wall; substantially as described. the other as is the case in the conventional 4. A folding box comprising a bottom,

walls hinged thereto, corner folds connected with two opposite walls and, foldable into the box, flexible strips for the upper edges of the end walls, and extensions on said end walls, the outermost one of which extensions is transversely out in two places, forming two end port ons which are wrapped around the strip and an intermediate portion which extends over such strip and is secured, to its end wall, said end portions being extended inwardly on their adjacent ed as substantially as described. v
