ALEXANDER w. nnnns, 0F BAToNNn, new JERSEY;

KNOCKDOWN PAPER Box.

SPECIFICATION forming part of Letters Patent No. 738,516, dated September 8, 1903.

I Application filed March 13, 1903. erial No. 147.554. (No modeld To all whom it may concern:

Be it known that I, ALEXANDER W. Bnnas, a citizen of the United States, residing at Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Knockdown Paper Boxes, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide an improved knockdown pasteboard or cardboard box of the class used by tailors and others for packing clothes and other articles and for shipping the same; and with this and other objects in View the invention consists in a box of the class specified constructed as hereinafter described and claimed.

In the drawings forming part of thisspecification, I have shown only one member of the box, said member being the bottom portion or box proper; but in practice the top or cover of the box is made exactly in the same way and is made large enough to go over the bottom member or box proper.

The invention is fully disclosed'in the following specification,of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of said views, and in which- Figure l is a plan view of a blank from which my improved box is made; Fig. 2, a perspective view of the bottom member or box proper; Fig. 3, a plan and side view showing the box or box member knocked down or folded together for shipment in quantities; Fig. i, a plan View showing the process of knocking down or folding the box into the position shown in Fig. 3; Fig. 5, a view similar to Fig. 1, showing a blank of modified form; Fig. 6, a plan View showing a box made from the blank shown in Fig. 5, knocked down or folded together,v and Fig. 7 a perspective View of a box made from the blank tion a are dotted or scored lines d, and between the side members 0 and the body portion a are similar lines e, and these lines are projected across the end members h, as shown at 6 The ends of the folding endl members are extended to form flaps b the outer side edges of which are cut off at an angle or inclination, as shown at 19 and the extensions 6 of the end members I) are separated from the folding side members 0 by slits or slotsf. The ends of the folding side members 0 are provided with heavily creased or scored diagonal lines 0 at an angle of about forty-five degrees to the dotted lines or scored lines c, whereby triangular flap members 0 are formed and the inner surface of these triangular flap members are preferably gummed over a portion thereof, as shown at g,}in order that the flap members 11 of the folding end portions 1) may be secured thereto, as hereinafter described.

Each of the folding side members a is provided with two locking-clips h, preferably of the form shown, and formed by means of slits h cut in said folding side members, and these slits and corresponding locking-clips are arranged at approximately equal distance from the ends of said folding side members and from each other, the distance between said slits and clips being slightly greater than the distance between said slits and clips and the ends of said folding side members.

In makingithe box or box proper shown in Fig. 2 from the blank shown in Fig. 1 the end members 17 are folded into an upright position, and the end flaps 19 thereof are folded inwardly, as shown in Fig. 2. The side members a are then folded into an upright position and that portion of the flap c which is gummed, as shown in Fig. 2,is sealed. to the end flap members I) of the folding portions 6, or this connection may be made in any desired manner by means of stitching or otherwise, if desired; but the edges of the flap members a of the folding side portions 0 of the blank and the inner. ends or adjacent ends thereof should be left clear in order to facilitate the operation of these parts, as hereinafter de- ICO scribed. When all the corners of the box have been secured in this manner, the sides of the box are bent or forced inwardly, and the locking-clips h are bent inwardly, and the in- 5 clined edges of the flap members 13 of the end portionsb are caught under said locking clips, as shown in Fig. 2. This securely holds the parts of the box or box proper in proper form, and in order to knock down the said box or box member or fold it up, as shown in Figs. 3 and 5, the end flap members b of the folding end members I) are detached from the locking-clips h, and the sides of the box are folded inwardly, this process being clearly in- 15 dicated in Fig. 4, and as the sides of the box are forced inwardly the flap members b also turn inwardly, the sides 0 fold flat on the central portion a or on the bottom of the box and the end portions 1) fold over said side por- 2o tions, as clearly shown.

parent that two box members made in this way, one of which serves as a box proper and the other for the cover, will constitute a strong and substantial box, both members of which may be folded together, as shown in Figs. 3 and 5, Whenever desired for packing or similar purposes. Any suitable flexible material may be employed .in the making of this box or box member, and the said box member may be made oblong, square, or of any desired shape.

In Fig. 5 I have shown a modified form of the blank shown in Fig 1 and in Fig. 7 a perspective view of a box or box member made from this blank, and in Fig. 6 the said 4obox or box member is shown in a knockdown or folded condition.

The blank shown in Fig. 5 is exactly of the same general form as that shown in Fig. 1, the only difference being that the slits which 5 separate the parts b and c and which in the form of construction shown are designated bythe reference character m are formed in the flap members 19 of the folding end portions 5, whereby the flap members 0 of the folding side members 0 are provided with supplemental flaps m which are gummed on their inner side. In making a box from this blank the end members I) and the flaps b thereof are folded exactly as in Fig. 4, after which the supplemental flaps m are folded around the end members and secured thereto. This leaves the folding flap members 79 entirely free, and they are engaged with the locking-clips it exactly the same as in the 6': construction shown in Fig. 4, when the box or box member is in condition for use. When this box or box member is knocked down or the separate parts thereof folded together, the flap members 19 0f the end portions b are detached from the locking-clips h and folded fiat against the end members I), and the sides 6 may be bent outwardly, as shown in Fig. 6.

This form of box or box member, however, may be folded exactly as shown in Figs. 3 and 4, if desired, in which operation the side membe'rs c are folded inwardly.

My invention is not limited to either of the forms herein shown and described for securing the side portions 0 to the end members I), all that is necessary in this connection being to provide means whereby the said side members and end members may be secured together at the corners of the box or box member, and this may be done by stitching, if desired. In either form of construction the flap members b? of the folding end members I) serve to brace the box or box member and to give the same strength and stiffness, and these flap members 12 may be left free or they may be secured to the flap members 0 of the folding side members 0, as shown in Figs. 2 and 4, and as hereinbefore described. When secured to the flap members 0 they have no motion or folding capacity independent of said flap member 0 but when the corners of the box are connected in any other way these fiap members b are free to swing either inwardly or outwardly when not connected with the locking-clips h, and when this form of box is knocked down or folded, as shown in Fig. 6, the creased or scored line 0 bends outwardly instead of inwardly, as

shown in Fig. 4.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A box or box member composed of a blank of flexible material comprising a central body portion having folding end portions and side portions, the end portions being of a length equal to the combined width of the body portion and the side portions, and the ends of the folding end portions being separated from the ends of the folding side portions by slits or slots whereby the ends of the folding end portions are provided with folding flaps, and the outer corners of said flaps being cut away at an acute angle to said slits or slots, the ends of the folding side portions being also creased or scored at an angle of forty-five degrees to the lines on which said side portions are folded so as to form triangular flaps and said side portions being also provided with inwardly and outwardly directed locking-clips formed by slits out therein below or within said creasing or scoring and which extend in the direction of the central end portions of the blank and with which the flaps of the end portions are adapted to engage so as to hold the sides and ends of the box or box member in an upright position, substantially as shown and described.

2. A box or box member composed of a bottom portion and folding side and folding end portions, the folding side portions being creased or scored at the ends and at an angle of forty-five degrees to the folding lines thereof to form triangular flaps and said portions being also provided within or beneath said flaps with inwardly and outwardly directed locking-clips formed by slits cut therein and which extend in the direction of the end portions of the box, the folding end portions of the box being also provided with inwardlydirected flaps adapted to engage said looking devices and the upper inner corners of Which are cut off at an acute angle to the top of the sides of the box, and the ends of the side portions and end of the folding end portions being connected to form the corners ,of the box, substantially as shown and described.

3. A box or box member composed of a bottom portion and folding side and folding end portions, the folding side portions being creased or scored at the ends and at an angle of forty-five degrees to the folding lines thereof to form triangular flaps and said side portions being also provided Within or beneath said flaps with inwardly and outwardly directed locking-clips formed by slits out therein and which extend in the direction of the bers at the ends of the end portions being also secured together, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 12th day of March, 1903.
