12 Claims.

This invention relates to le boxes and it is an object of my invention to provide an inexpensive book-like file box for periodicals, maps, newspapers and the like, which may be shipped flat and subsequently easily assembled into a rigid le of attractive appearance.

In general, these objects are accomplished by providing a file box formed of moderately stiff cardboard consisting of two elements. The inner element is formed from a rectangular piece of cardboard into a rectangular box-like structure having open ends by creasing the cardboard parallel to its shortest dimension at suitable points and gluing the ends together. The outer element is formed of similar material and is creased to fold around the inner element. The ends of the outer element are provided with flaps adapted to be tucked into an open end of the inner element. The inner element does not have rigid reinforcements at the corners and may, therefore, be collapsed. After assembly, however, collapse of the inner element is prevented by the action of the flaps on the outer element. My le m-ay, therefore, be shipped at and easily assembled at its destination without the use of glue or special tools into a rigid le box.

Other objects will become apparent from the following detailed description and from the drawing, in which Fig. 1 is an exploded view showing the general configuration and relationship of the component parts;

Fig. 2 is a perspective view of my assembled file box; and

Fig. 3 is a horizontal section taken along the line 3-3 of Fig. 2.

My le box consists of an inner element generally designated II, and an outer element generally designated I2, which may be formed from a variety of semi-rigid materials such as solid kraft or ordinary cardboard, lined cardboard, cloth covered cardboard or covered corrugated paper board. The inner element I I is formed from a rectangular blank of such material and comprises a' flange section i3, a side I 4, a top I5, a side I6, and a base I'I. To construct this element, the blank which is originally flat, is creased along a line designated I8, parallel to an end I9 and spaced therefrom a distance approximately equal to one half of the desired width of the inner element. Another crease 2l is formed parallel to the first crease I8 and spaced therefrom a distance equal to the desired height of the inner element. A third crease 22 is formed parallel to the second crease 2| and spaced therefrom a distance equal to the desired width of the inner element II. A fourth crease 23 is formed parallel to crease 22, the distance between creases 22 and 23 being substantially equal to the distance between creases I8 and 2l. The distance from crease 23 to end 2e is made substantially equal to the distance between creases 2I and 22,

The inner element I I is assembled into its final form by folding the blank inwardly at each of the creases and fastening the flange section I3 to the base I l by glue or other suitable means. As no reinforcement is used at the corners, the inner element may be folded into a llat section by moving the side I6 parallel to the side I4 until the two sides are in contact, thereby permitting shipment in a flat condition.

'.Ihe outer element I2 is also formed from a substantially rectangular blank, the width of this blank being purposely made somewhat greater than the overall height of the inner element so that the assembled file will closely resemble a book. The width of the blank adjacent to each end, is reduced to dene, in conjunction with creases 26 and 21, flaps 28 and 29, the Width of the blank being made substantially equal to the distance between creases I8 and 2I on the inner element. The creases 26 and 2l are spaced inwardly from the respective ends of the blank, a distance slightly in excess of the width of the inner element and are parallel to the ends of the blank. Another crease 3l is formed parallel to crease 26 and spaced therefrom a distance equal to the depth of the inner element, dening a side 32. A crease 33 is formed similarly with respect to crease 2'I, dening another side 34 of the outer element. Greases 3l and 33 are spaced apart a distance substantially equal to the overall Width of the inner element II, and denes the back 3S, which may be decorated or treated upon its external surface to closely resemble the back of a book.

The outer element I2 is preferably covered or printed with some design on its o-uter surface to present a pleasing appearance after assembly. The exterior portion of the back 36 may be printed, embossed, decorated by the silk screen process or provided with a suitable label to indicate the contents of the le, or an opening may be formed therein suitably positioned to reveal the title of the book or magazines within the le, the outline of such an opening being designated by the dot-` ted line 35 in Fig. 1.

In shipment, the inner element may be collapsed in a manner previously described and the outer element folded at, thereby making a compact parcel for shipment. Upon arrival at its destination, the file may be easily assembled by placing the nap 23 in an open end of the inner element II, folding the outer element I2 around the inner element il and finally inserting the other nap 29 in the same open end of the inner element as flap 2B. As the naps 28 and 29 are purposely formed with a width in excess of the Width of the inner element, unintentional withdrawal of the naps is prevented. These naps, after being folded into the inner element, prevent collapse of the le and impart rigidity to the structure. It is to be noted from Fig. 3 that the flaps 28 and 29 are of suicient length that, when they are brought together inside the inner element Il, an acute angle is formed between the flaps on the side facing the open end of the box. The naps also hold the sides 32 and 34 of the outer element I2 snugly against the sides I4 and I6 of the inner element II, providing in effect a double wall section which greatly increases the strength and durability of my file.

Due partially to the inherent resiliency of the materials used to form the outer element I2, and partially to the Width of the sides of the inner element I I the naps 28 and 29 Will tend to spring inwardly towards each other within the inner ele.. ment, except, of course, when the le is completely filled. As shown in Fig. 3, this action of the naps tends to hold the contents of a partially lled le in a vertical position and also tends to hold the contents in place when the le is accidentally tilted.

Certain of the details mentioned in the foregoing description may be modified. For example, it is not essential that the outer element I2 have a height greater than that of the inner element, although it is believed that this contributes to the appearance of my iile. Likewise, the aps on the end of the outer element I2 are not necessarily integral therewith, but may be attached by tape or other suitable means.

The utility of my le appears to be obvious from the foregoing description. Magazines, books, maps, papers, bulletins, recipes, pictures, correspondence, and the like, which would ordinarily be piled on library shelves in horizontal position may be placed in my file and be retained in vertical position, thereby greatly increasing the accessibility of the material, economizing on storage space and improving the appearance. It is also apparent that my file is not only economical to manufacture, but also is easily assembled by unskilled purchasers and users, Without the use of glue or other fastening means. Economy of materials is effected by the use of rectangular blanks, which may be cut and formed Without waste.

The foregoing detailed description has been made in compliance with section 4888 of the Revised Statutes, but I do not wish to be specifically limited to all of the details herein set forth, as obviously certain modifications may be made therein without departing from the true spirit and scope of my invention as defined in the appended claims.

I claim:
