Patented on. 22, 1935 UNITED, STATES PATENT OFFICE 4 Claims.

This invention relates to boxes such as are made from heavy paper, cardboard, fiberboard, and like materials, and especially to foldable boxes which may be manufactured in a flat or 5 knock-down form and which may be quickly unfolded and erected when required.-

The object'of the present invention is generally to improve and simplify the construction and operation of boxes of the character described; to

10 provide a box which can be folded and assembled froma single blank and the parts secured with a single tab, either glued or stapled; to provide a folding box formed from a single blank which lends itself to great variation in height, width, 5 length and depth; to provide a blank or box of the character described which can be cut with a minimum of. waste; to provide a folding box having'an integral cover, said cover being applicable either to the side or end of the box as conditions may demand; and, further, to provide a folding box which, when assembled, presents double ends and a double bottom and which can be formed from a minimum amount of material.

The construction of the box is shown by way of illustration in the accompanying drawings, in which- Fig. 1 is a plan view of the-blank from which the box is formed.

Fig. 2 is a plan view showing the first folding operation of the blank.

Fig. 3 shows a second folding operation.

Fig. 4- shows the third folding operation.

Fig. 5 shows the fourth folding operation, which completes the folding and assembling of the sections.

Fig. 6 is a perspective view showing the manner in which the box is unfolded or erected from the folded blank shown in Fig. 5.

Fig. 7 is a perspective view showing the box 40 fully unfolded, but before the inner bottom section is folded into place.

Fig. 8 is a plan view showing a modified form of blank in which the cover section is applied to the end of the box.

Referring to the drawings in detail, and particularly Fig. 1, which is a plan vew of the blank forming the box, it will be noted that the blank may be made of any suitable material but is pref erably cut from cardboard, fiberboard, heavy 00 paper, or like material.

The blank is cut from stock by die operation and the shape obtained is that shown. Simultaneous with the blanking operation the paper is also creased along the lines indicated 55 at 1.2.1. 4. 5. .1. a. l9 and The time tab H, which will hereinafter be referred was 5 the glue tab.

The crease line I forms a flap l8, while the section formed between the crease lines I and 2 forms a cover l9. Opposite the cover section l9 and below the crease line 3 is an interior bottom 10 section 20. Above the exterior end section l5 and formed by the crease line 2 is a tab 2|. Below the exterior end section l5 and formed by the crease lines 3, 1 and 8 are a pair of interior end sections 22 and 23 which are folded one 1 upon the other along the crease line I when the boxes are unfolded as will hereinafter be described.

Formed below the side section 14 by the crease line 3 is an exterior bottom section which is divided into two sections 24 and 25 by the crease line 9, extending diagonally across the same. The crease line H) forms an interior end section 26 and the crease line 2 above the exterior end section l6 forms a tab 21. 25

The blank when completed may be said to consist of a central strip composed of the securing tab II, together with the side and end wall sections indicated at I2, I 5, l4 and I6. The other sections forming the inner ends 22 and 26 of the 30 boxand the double bottom sections 24, 25 and 26 are formed on one side of the strip and the cover l9 may be formed on the opposite side of the central strip or as an extension of the end section I6 as shown in Fig. 9.

After the blank has been cut and formed as shown in Fig. 1, it is first folded longitudinally along the crease line 3 and will assume the position shown-in Fig. 2. Thereafter, the interior end section 26 and the section 25 of the interior bottom section are folded upon the section 24 on the exterior bottom section, as shown in Fig. 3. Glue is next applied to opposite sides of the tab l1 and the sections l2, l9 and 20 are folded on the crease line 5 so as to assume the position shown in Fig. 4, and as glue has been applied to both sides of the tab I! the tab II will adhere to the interior end section 26. The last and final operation is that of folding the exterior ,end section l6 on the crease line H so as to overlie the interior end section 26 and the glue tab I! and this position is shown in Fig. 5. This completes the folding and assembling of the blank and the product is a folding box in the flat knock-down form. In this condition it shape the exterior bottom section will flatten out along the crease lines 9 and I 0, finally assuming a flat position such as shown in Fig. '7. The interior bottom section 20 is then folded down over the exterior bottom section formed by the parts 24 and 25 and the box is ready for use.

A box folded in the manner described can be made from a minimum of material. The blank from which it was formed lends itself to great variation in height, width, length and depth when box construction of this character is considered.

The cover section l9, shown in Figs. 1, 6 and 7,

is shown as attached to the side of the box. 7

' However, by referring to Fig. 8, it will be noted that the cover section is attached to the end of the box. This is another advantage as it ,increases the utility of the box by permittingthe cover to be attached either to the side or 'to the end of the box. Also, by attaching the cover section to the end of the box saving in material is obtained during the blanking operation.

comparatively little waste is encountered in the blanking operation as the blank is so shaped that nesting of the blanks becomes possible, the waste being at a minimum when the cover is attached to the end of' the box.

' The box, when assembled, is'exceedingly rigid in construction as double ends are formed by the sections l5 and 2G and a substantial triple-thick end is formed by the sections I5, 22 and 23, and a double bottom is formed by the member 20 overlying the sections 24 and 25. The box, when unfolded and erected, is thus stiff and rigid and it lends itself for the reception of articles of varying nature. For instance, it may be used for a candy box, sandwich box, spools, and also for heavier articles such as toys, small metal parts, and the like.

The assembling operation from the blank form shown in Fig. 1 can be readily accomplished by machine operations, as each folding operation is exceedingly simple and as glue is applied to both surfaces of the tab H the assembling and securing of the several sections with relation to each other is accomplished by the glue tab during the folding operation to which the blank is subjected.

Great quantities of these boxes may be carried in stock as they are received in a flat or knockdescribed, I wish it' understood that various changes may be resorted to within the scope of the appended claims. Similarly, that the materials and finish of the several parts employed may be such as the manufacturer may decide, 5

or varying conditions or uses may demand.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:--
