UNITED STATES PATENT OFFICE.

GEORGE ROERIG. 0E ATLANTA, GEORGIA, .ASSIGNOR TO ATLANTA PAPER COMPANY,

or ATLANTA, GEORGIA, A CORPORATION or GEORGIA.

Be it known that I,.GEoRcE ROEBIG, ,a citizen of the United States, residing at :Atlanta, in the county of Fulton and State of Geor ia, have invented certain new and useful Improvements in Collapsible Flexible Boxes and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements .n flexible boxes, and particularly with relation to that class of flexible boxes which are so, constructedas to fold fiat and be turned or folded up into proper position when they are to be used as a box.

The primary object of this invention is to provide a box formed from a single fiat blank, without slits or projections, which can be folded flat and which can be turned up and the ends and side walls so secured as to form a very rigid structure.

\Vhile the invention not restricted to the exact details and fastening means shown, still for the purpose of disclosure reference is bad to the accompanying drawings illustrating a practical embodiment of the invention, and the particular features of novelty will be more particularly pointed out in the claim.

fragmentary perspective view of the body portion of the box as it appears when the sides are turned up but just before finally securing the end and side walls. Fig. 3 is an interior perspective view of one corner of the body ortion of the box with the side and end wal s firmly secured together. Fig. 4 is a plan view of a rectangular'blank for forming a rectangular box or box top, the dotted lines showing thepositions of scoring or creasing to enable the side and end walls of the box or box top to be turned up,

and Fig. 5 is a detailed View of one of the fastening staples.

It will be understood that the invention is for the construction of a collapsible box member, and that therefore either the body portion of the box or the top member may be used interchangeably with its complementary part even if of different construc- "OLLAPSIBLE FLEXIBLE BOX.

tion, but it is desirable that both portions.

be constructed in thesame way, and in the drawings therefore the cover or top is shown constructed the same as the body portion of the box excepting that it isformed from a blank. the area of which between the scored lines is slightly greater than that of the body portion in order that the top may fit thereover: In the description for brevity i simply refer to the body portion of the 1 designates the base, 2 the side walls, and 3 the end walls. The side walls 2 are separated from the base by the longitudi nal scoring 4 and the end walls are similarly separated by the transverse scoring 5, and where these lines of scoring intersect there is formed the corner ortions diagonally scored as at'fi to provi e for an internal fold when the box is turned up. These corner portions form triangular portions 8 and 9 which register when the box is in its turned up position.

To further describe the invention I will now refer to the blank after'it has been first folded.

Taking the blank as shown in Fig. 4, the side walls 2, in conjunction with the. sections 8 and 9, are-bent inwardly along the scoring lines 4, and are folded flateon the bottom 1 of the box. The triangular portions 8 may then be securely aflixed to the end walls 3 by means of the staples 1G, and similarly the pointed ends of the fastening clips 11 are passed through the end body portion of the box member and'the same triangular sections, as illustrated in Fig. 2. The clips 11 consist of a body portion having pointed ends bent at right-angles and are also provided with projecting.

tongues 12. v

The foregoing paragraph describes the normal position of the knockdown box. When the box is to be folded up the walls 2 are bent outwardly and the end walls 3 are bent inwardly, so that the walls assume a vertical position, as. shown in Fig. 2, with the adjacent faces of the triangular portions 8 and 9 lying against each other. In this position the pointed ends of the staples 11 lie hidden when the box member is struck up, and the projecting. tongues are bent over the portion of the box to which the staple is secured and also over both walls of the triangular sections 9 of the folds, the

side walls being thereby secur 1y aflixed to the end walls, allas shown in 1g. 3. What I claim is A collapsible flexible box, formed from a flat integral blankscored transversely and longitudinally to supply turned up side and end walls; said Walls joined with an mtegral internal fold at each corner of said box member; each of said folds consisting of a pair of substantially triangular por tions having bases flush with the eri pheral edge of thebox member, means ocated on the outside of said box, passing through one of its walls and through one of said triangular portions, and fixedly securing the latter to the former and comprising a member for detachably securing the correspondv to be bent over the body portion of the box member, and also over the base edges of said triangular portionsfor securely holda ing the sad corner folds together, substantially as d scribed.

In testimony whereof, I aflix my signa ture, in presence of'two witnesses.
