BEULAH L. DOZIER, OF EAGLE PASS, TEXAS.

COLLAPSIBLE BOX.

Application filed September 13, 1922. Serial No. 588,023.

To all whom it may concern:

Be it known that I, BEULAH L. DozIER, a citizen of the United States, residing at Eagle Pass, in the county of Maverick and State of Texas, have invented certain new and useful Improvements in Collapsible Boxes, of which the following is a specification.

My invention seeks to providea collapsible or foldable box which may be produced from. a single integral piece of material and which will provide a. complete closure and handle. I also seek to provide a box which will retain its form when in use but which may be collapsed when not in use so that a large quantity may be stored within a small space and a used box may be easily returned to a shipper for further use. The stated objects and other objects WhlChWill incidentally appear in the course of the following description are attained in such a structure as is illustrated in the accompanying drawings, and the invention resides in certain novel features which will be particularly pointed out in claims following the description.

In the drawings Figure 1 is a. perspeotiy e view of my improved box as it appears when fully closed and in use;

' Fig. 2 is a similar view showing the box partly opened;

Fig. 3 is an enlarged edge view of the box in collapsed condition;

Fig.4 is a perspective View of the box with the closing flaps in opened pos1t1on;

Fig. 5 is a. plan view with the walls in horizontal section;

Fig. 6 is a detailsection on the line 6-6 of Fig. 5; j

Fig. 7 is a plan view of the blank;

Fig. 8 is a detail section on the line 88 of Fig. 7.

In carrying out my invention, I employ a blank of paper, leather, cloth, or any other desired material which may be easily folded. Theblank is shown in Fig. 7 and comprlses a central rectangular portion} having a plurality of tongues or flaps pro ecting from its longitudinal edges Along one longitudinal edge at the center of the same is a rectangular fla 2 which is scored transversely, as in dicate at .3, the scoring being disposed nearer the outer than the inner end of the flap so that in the completed box the score or crease will be disposed centrally of the somewhat beyond the free edge of bottom thereof. Of course, the flap may have I the full dimensions of the bottom of the box in which event the scoring will be midway the inner and outer ends of the flap. Between the flap 2 and the ends of the central body 1 of the blank are shorter flaps 4 which, are duplicates inform and dimensions and are scored, as indicated at 5, so as to be divided into two equal sections, and it will be noticed that the said scoring 5 extends across the main body of the blank and to the ends of the alined flaps at the opposite edge thereof. At the ends of the blank are additional flaps G which are not scored but which are of less length than the flaps 2 and i. The longitudinal edge of the main body is defined by scoring 7 which extends from end to end of the blank at the bases of the several flaps 2, 4 and 6. The blank is further scored transversely, as indicated at 8, the said scoring 8 being alined with the edges of the flaps 2, 4 and 6, as clearly shown, and the spaces between the said lines or scoring forming the sides of the completed box. At the upper longitudinal edge of the blank, there is formed centrally a. flap 9, the width of which is equal to the distance between the lines of scoring 3 and 7 so th'at the edge of this flap 9 will be disposed centrally across the top of the completed box. From the end or free edge of the flap 9, a. substantially semi-circular loop 10 projects and this loop 10 will form a handle in the completed box. The flap 9 is further provided adjacent its side edges with slots 11 which are alined and are disposed p'arallel with the free edge of the flap. The adjacent side edge of the body portion of the blank is defined by a line of scoring 12 which is parallel with the free edge of the flap 9 and extends the full length cf the blank. From the edge of the blank immediately adjacent one end of the flap 9, extends a rectangular flap 13. This flap 13 has its free edge beyond the free edge of the flap- 9 and is provided with slots 14 disposed at a right angle to the adjacent side edge of the blank and located between the lines of its own free edge and the free edge of the flap '9, as clearly shown in Fig. 7. These slots 14 'are also disposed midway between the side edges of the flap and the scoring 5 which extends across the flap. A djacent the opposite end edge of the flap 9 is a flap 15, the free edge of which projects and is longitudinally' slit, as indicated at 16,

whereby to form tongues 17. In the completed box, the tongues 17 are engaged in the slots 14 and will frictionally engage. the walls being efined by a slit 22 cut inwardly from the free end edge of the flap.

It is, of course, obvious that the several flaps are to be folded inwardly relative to the main body of the blank to form the completed box and the flaps at the lower side of the drawing will constitute the bottom of the box, while the flaps at the upper side of the drawing will constitute the top or closure for the box. To reinforce the upper flaps and guard against tearing or other injury to the same through careless handling, I provide a lining 23 which may be of thin cloth or textile material or may be of any material possessing the requisite strength and flexibility. This lining is, of course, cut

to correspond exactly with the shape of the several flaps 9, 13, 15 and 18 and is secured to the inner surfaces of said flaps by any suitable adhesive. As shown-in Fig. 7, the inner edge of thelining is preferably carried over onto the main body of the blank so that the fold or joint between the main body of the blank and the respective flaps will be reinforced and splitting of the same prevented.

In manipulating the blank to produce the box, the flap 2 is first folded to assume a position at right angles to the inner surface of the main body of the blank. The blank is then folded along the lines of the innermost scoring 8cso that the panels carrying the flaps 4 and 13 and 4 and 15 respectively will be brought into position at right angles to the central panel of the blank and the flap 2. The flaps 4 will thus be brought against the outer surface of the flap 2 and will be secured thereto by adhesive, the end portions of the scoring 5 coinciding with the scoring 3 so that the completed bottom. of the box may be folded inwardly, as shown in Fig. 3. The end panels of the blank-are then folded upon the outermost lines of scoring'8 so that they will assume an overlapping relation and lie at right angles to the intermediate panels and parallel with the central panel of the blank. The flaps 6 will be thereby caused to overlap portions of the respective flaps 4 and the ends of. the said flaps 6 will overlap. The flaps 6 may then be secured to the flaps 4 and to each other and to the portion of the flap 2 beyond the scoring 3 by adhesive so that the bottom of the-box Will be completed. It is to be panels of the blank are of such width that their meeting edges will overlap somewhat and these overlapped edges are joined by adhesive, as will be readily understood. he overlapped edges are shown at 24 in The box completed as so far described will have the form shown in Fig. 4, but the lines of scoring upon the intermediate panels of the blank will permit the box to be collapsed,

as shown in Fig. 3, so that the prepared boxes may be stored in quantities within a small space and no time is lost in preparing the box When the use of the same is needed. The box, as shown in Fig. 4, is set up on end when the use of the same is desired, as indicated in Fig. 6, and the article to be carried is deposited in the box through the upper end of the same. The flap 13 is then folded over across the open top of the box and the flap 15 brought over upon the said flap 13, the tongues 17 being thereby brought into such/position that thev may be readily engaged in the slots 14 and thereby hold the flaps 13 and 15 together. When the box is formed, as shown in Fig. 4, the flaps 18 will partly overlap just as the end panels of the blank overlap and the overlapped portions of the said flaps 18 are secured together by adhesive. The notches or openended slots 19 will thus be brought into alinement and will constitute a slot having closed ends through which the loop or handle 10 may be inserted. To complete the, closing of the box, the handle or loop 10 is inserted through the completed slot 19 and the flaps 9 and 18 folded down onto the flaps 13 and 15, the tongues 21 being thereby brought into position to engage the slots 11 through which they are inserted, as shown in Fig. 1, after which the loop or handle 10 is bent upwardly so as to project from the completed box. It will be readily seen that I have provided a box which may be easily assembled for use and which may be stored in a very compactspace and which may be produced at a low cost. The device is intended more particularly for use in delivering hats but it ma of course, be used for various purposes. TTotwithstanding the inexpensiveness of the box, it will be strong and durable and may be repeatedly used.

Having thus described the invention, what is claimed as new is:

1. A blank for a box consisting of a single integral sheet of foldable material comprismg a central rectangular body portion, and flaps extending from the longitudinal edges of said body portion, the central flap at one side edge of the bodyportion being provided at its free edge with an outwardly projecting loop and having slots adjacent 1ts side edges disposed parallel with the adjacent edge of the body portion of the blank, a flap adjacent one side edge of the said central.
