ELHER LUPTON, OI BALTIMORE, MARYLAND, ASSIGNOIR TO THE BARTGIS BROTHERS (70., OF BALTIMORE, MARYLAND, A CORPORATION OF MARYLAND.-
rommet Box.
Application filed August 23, 1927. Serial No. 214,968.
This invention relates to folding boxes, made of paper stock and suitable for containingsuits, coats, etc. The purpose of the invention is to provide a box with attached cover-which can be quickly set up or knocked down, which will fold flat for shipment, and which will occupy small space on the counter while the goods are being packed inthe boxes.
The box comprises top and bottom portions which are made separately from similar blanks, the blankfor the topor cover portion being slightly larger than the 'blank for the bottom portion of the box. Each blank comprises a substantially rectangular to provide walls for the box part and creased diagonally at itscorners so that the latter may fold against opposing walls, and also having flaps projecting from two of its opposite edges, adapted to fold over the adjacent walls and corner pieces. These flaps, on the bottom portion of the box, are secured in their central portions to the adjacent walls, the ends of the flaps being free. A blank of this general character and a box part made therefrom are illustrated in patent to Bachmann, No. 855,746, although in the patent referred to, the flaps are at the ends of an oblong box," where the extra thickness caused by the flaps and corner pieces on both parts of the box is undesirable; whereas, in my oblong box I arrange the flaps on the side walls to strengthen the box longitudinally. The bottom portion of the box of my invention is made with the cured to the side walls; whereas on the top or cover portion only one flap is turned inwardly and secured to the adjacent sidewalls and the other flap is creased so that it may fold either inwardly or outwardly with respect to its side wall, and this fla is secured by stitching, or otherwise, to the, ase or bottom of the bottom part of the box, withthe crease running parallel with the side of said part. In this way, the two parts of the box are permanently secured together and the one part will fold flat against the other. In setting up thebox, the bottom portion is first set up by pulling both of its side flaps out-- wardly, and the top part is set up by pulling one side flap outwardly, after which the top part is swung over the bottom part to make the complete closed box.
In the accompanying drawing,
Fig. 1 is a plan view of a blank, suitable for body portion, creased parallel with its edges,
flaps at both sides turned inwardly and see,
forming either the top or the bottom of a box;
Flg. 2 1s a perspective View of the box folded for shipment;
F g. 3 is a section on the line 33 of Fig. 2.-
Fig. 4 is a perspective view of the box with the'bottom part set up for filling, and the top part folded;
Fig. 5 is a similar view, with the top part set pp and ready to be closed over the bottom P Fig. 6 is a transverse section through the closed box; and,
Fig. 7 is a perspective View of a. corner of the box,showin the manner in which the corner pieces fold under the side flaps.
Referring to the drawing, the top and bottom portions of the box are each made from a blank of the form shown in Fig. 1, the blank for the top part of the box being, of course, slightly larger than the blank for the bottom part, since the former part fits over the latter. The blank comprises a substantially rectangular body portion a and side flaps a. As shown, the blank has creases 1 extending across it parallel with its ends, and creases 2, extending lengthwise parallel with its sides, and-it is also creased longitudinally in line with the sides of the body portion, as shown at 3. The flaps a may bend with respect to the body portion along the creases 3, and these flaps end substantially at the creases 1. The
corner portions 4 of the blank are diagonally creased, as indicated at 5. The parts .6 of the blank, between the creases 1 and the ends of the blank, constitute the end walls, and the parts 7, between the creases 2 and 3, constitute the side walls of one part of the completed box; In making the bottom part b of the box from ablank, the end walls 6 are turned inwardly over the main part ofthe blank, as shown in Fig. 2, and the fla s a .are'turned inwardly over the side wa ls 7,
.wall' 7 in the same way that the corresponding parts are folded in the bottom part .7) of the box. The flap a of the top 0 is, however secured to the bottom 1 of the bottom part of the box by suitable means, such as stitches 9. The crease 2, which divides the flap a from the adjacent side wall 7 b of the top portion of thebox, constitutes a hinge joint which liesparallel with the lower edge of one of the sidewalls of the bottom part of the box, as shown in Fig. 5, so that the top 0 may fold flat under the bottom I) of the box, as shown in Figs. 2, 3 and 4. As shown in Fig. 5, one
fold 4c" of each corner piece on the top, adjacent the side wall 7", is secured to said side wall by a stitch-or staple 10. This is not essential', but is desirable for the urpose of effecting automatic folding oi the corner 5 pieces.
In practice, when it is desired to set up a box, the folded structure is laid with the top or cover part 0 upon a table or counter, and by pulling outwardly on the end walls 6 of the part b, thecorner pieces 4 fold partly, as indicated in Fig. 7. .The side walls 7 are then raised and the free ends of the flaps thereon are swung over the corner pieces and the bottom part of the box is then set up, as
showninFig.4,andthebox may then be filled. The setting up of the bottom portion 7) of the box may be done Ver quickly, and it the top portion isleft folde under the bottom portion, very little space will be required on the counter or table while the box is being set up and filled. After the box has been filled, it is lifted and the top portionp is swung outwardly and its end walls 6 and the side wall 7 a are raised, as'shown in Fig. 5, the flap on the latter wall covering the adj aeent corner pieces. The cover may then be swung over the bottom part of the box. In this movement, the cover bends along the hinge joint formed by the crease 2 and the ad'acent cor- 40 ner pieces automatically fold along their diagonal lines. When the box is closed, the
top or cover part of the box extends completely over the bottom part and the side walls 7 and 7" of the formerlie close to the sidewalls 7 of the latter. The sides of the box are thus very much strengthened by the several thicknesses of material, which is an advantage, particularly in relatively long boxes, such as are used for holding coats, suits, etc.
To knock the box down, it is merely necessary to swing the cover outwardly, as shown in Fig. 5, and press the side walls of the parts outwardly, thus releasing the corner pieces from the flaps, and the end walls will then fold'inwardly.
What I claim is:
Afolding box comprising top and bottom parts formed from similar blanks, each blank comprising a rectangular portion creased parallel with its edges to form walls and creased to form flaps on two opposing walls, and the corners of said portion being creased diagonally to fold against said opposing walls, said flaps, on the bottom part of the box, being folded inwardly and secured at their central portions to their adjacent walls, the end portions of the flaps being free, to permit the adjacent corner pieces to fold thereunder, one flap on the top part of the box being similarly folded and secured at its central portion toits adjacent wall and the other flap on the top part of the box being secured to the bottom part of the box with the crease forming said latter flap extending along a lower edge of the bottom part and forming ahinge joint permitting the top part to swing on said joint over or under the bottom part.
In testimony whereof I hereunto aifix my signature.
