BOX.

Application filed March 11, 1924. Serial No. 698,520.

To all whom it may concern:

Be it known that I FREDERICK A. Rose, a object of the King of Great Britain, residing at Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Boxes, of which the following is a specification.

'lvlysaid invention relates to a collapsible paper box and it is an object of the same to provide a box which can be shipped 1n collapsed or knock-down position but which whenopened is practically as rigid as any stiff box on the market.

Another object of the invention is to provide a collapsible box with a bottom which when once forced into place will hold its position firmly and which bottom cannot be folded again or is at least so nearly impossible to refold as to insure that the box will not collapse by accident.

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts,

Figure 1 is a perspective of my improved device,

Figure 2, a vertical section of the same in partly open position,

Figure 3, a section at a corner next to one end of the joint in the bottom of the box with parts broken away.

Figure 4, a perspective of the bottom in operative position with parts broken away to show the construction more clearly,

Figure 5, afragmentary plan of the bottom, and

Figure 6, a fragmentary perspective at one corner.

In the drawings reference character 10 indicates the outer wall of a box having a bottom consisting of duplicate sections 11 and 12 each forming one-half of the bottom. These sections have downwardly extending flaps which are rigidly united as indicated at 13 and a strip of material 14 is inserted between such downwardly extending flaps said material terminating short of the ends of the joint as clearly shown in Figures 4 and 5. A staple 15 is indicated by Figure 5 as providing means for uniting the flaps 13 and the strip 14 but any other desirable or conventional means may be provided for this purpose. The top edges pf S de 1? are preferably reinforced by inturned flanges which stiffen and brace the structure when the box is closed.

At the sides parallel to the joint of the bottom sections the lower ends of sections 11 and 12 are crimped to form flaps 16 which extend beneath a flap 17, the latter flap being continuous about the bottom of the box or substantially so to provide a strong bottom rim or edge for supporting the box. The outer crimped edges 16 of the bottom sections 11 and 12 are secured to the flap 17 and to the outer wall of the box by rivets or glue or in any other convenient manner. At the remaining sides of the box the outer crimped edges 16 of the side sections slip behind the flap 17' when the bottom is forced downward into operative position.

The outer wall of the box preferably consists of two duplicate sections having in.- wardly folded flaps secured together by glue or the like to form guides 18 for the spaced-apart projecting outer ends 19 of the flaps 13 by which the bottom sections are connected to each other, (Fig. 5), these flaps being secured together by glue or the like and held apart at the ends by means of the strip 14 for convenience in position ing the bottom in relation to the guides 18. It will be seen that the spaced outer ends 19 can slide freely down along the guides 18 in opening the box.

Extensions 19 are preferably cut back at 20 (Fig. 4) for convenience in sliding the bottom to position since otherwise the cor- 11ers might catch against the wall of the box. The guides 18 are cut away at the level of the bottom as indicated at 21 in Figure 6 so that the ends of strip 14 will slide past and underneath the shoulder thus formed thereby locking the parts together since the end of the strip 14 cannot pass the shoulder in the reverse direction. Preferably this look is so strong that it is necessary to damage the box before the strip can be disengaged from the shoulder, this making it a very satisfactory device in use due to the absence of accidental collapse of parts. It will be obvious to those skilled in the art that various modifications may be made in my device without departing from the spirit thereof and therefore I do not limit myself to what is shown in the drawings and described in the specification but only ;as indicated in the appended claims.

Having thus fully described my said incorners for guiding the sections of the bottom, and means at said corners for locking the bottom in position when fully opened,

substantially as set forth.

A collapsible box comprising collapsible side members, a folding bottom, flanges projecting inwardly from opposed corners of the box at the ends of certain of said joints for guiding the bottom sections said flanges being cut away adjacent their lower ends to provide shoulders adapted to extend over the bottom sections to lock the bottom in place, substantially asset forth.

3. A box comprising collapsible sides, a folding sectional bottom, guides projecting inwardly of the box at opposite corners said guides engagingbetween sections of the bottom, and a strip of cardboard or the like separating the sections of the bottom and terminating short of saidopposite corners said strip being of substantially equal thickness with said guides, substantially as set forth.

4. A box comprising collapsible sides, a folding sectional bottom, guides projecting inwardly of the box at opposite corners said guides engaging between sections of the bottom, a strip of cardboard or the like separating the sections of the bottom and terminating short of the corners said strip being of substantially equal thickness with said guides and said guides having shoulders adjacent their lower ends adapted to engage over the strip when the box is fully open substantially as set forth.

In witness whereof, 'I have hereunto set my hand and seal at Memphis, Tennessee, this 1st day of March, A. D. nineteen hundred and twenty-four.

FREDERICK ARTHUR ROSE. [L. s.]
