FOLDING BOX.

Specification of Letters Patent.

Application ined :any s, 1915. serial No. 37,837.'

17 '0 all whom it may concern Be it known that I. FRANK H. HoUGI-r- Lann, a citizen of the United States. residing at Cincinnati, in the county of Hamilt0n and State of Ohio, have invented certain new and useful Improvements in Folding Boxes, of which the following is a specification.

This invention relates to improvements in folding boxes and more particularly to the type of box having` the folded corners, one object of theI invention being the provision of a box of this character which can be made with the least waste of material and which when assembled in`form will be properly reinforced without liability7 to breakage as is eommonlythe case with boxes of this type.

A further object of the present invention is the provision of a box of this type which as it is formed or moved from its 'fiat position to a tray or box forming position will cause the locking members thereof to move toward locking position and thus make such operation a'simple and easy one.

IVith the foregoing and other objects in .View which will be evident as the description proceeds, the present invention resides in the features hereinafter set forth and particularly claimed.

In the accompanyingdrawings: Figure 1 is a perspective view of. the inner corner of one form of box embodying the present invention. Fig. 2 is a similar view thereof just previous to the extension of the side wall and the locking of the corner. Fig. 3 is a similar view to Fig. 2 taken from the opposite side. Fig. -1 is a plan view of one corner of the blank. Fig. l is a similar view of a modified form. Fig.y 5 is a perspective view of another modified form of lock corner. Fig. 6 is a plan view of the blank thereof. Fig. 7 is a perspective view ofanother modified form of lock corner. Fig. 8 is a plan view showing oneend of the blank therefor. Fig. 9 is a detail view of a blank showing a modified form of incision for receiving the lock.

Referring to the drawings, the numeral 10 designates the blank which is scored at 11 and 19. to provide the end wall 13 and the side wall 14, these walls-being further scored as-at 15 and 16 to further provide the fold Ain corner ap 17. This corner flap is scored diagonally as at 17 so that it may be caused to assume the position as shown in Figs. 1,

plemental iiap 1S to lock the corner flap relative thereto so that the box may be collapsedv in a fiat relation or be extended to the various positions shown in Figs. '2 and 1, respectively.

In the modification shown 'in Fig. 4'@ the flap 17 is provided with the angular cut away portion '22, the supplemental flap 18 being cut to the crease line 17a.

In the construction shown in Figs. 5 and 6 the same details as shown in Figs. 1 and 4 are carried out except that the end wall 13 is provided with the fold in edge 22 which is held in place over the edge of the corner flap 17h b v means of the staple 21. By this means the reinforcement is provided the full length of the free edge of the wall 13.

In the construction shown in Figs. 7 and 8 the lock 19 is cut with the least .vaste of material to provide a relatively long staple receiving supplemental Hap 1S', the curved `edge .of the lock being substantially contiguous at the greaterportion thereof with the flap 1S while a portion thereofbetween the crease and the curved edge provides .1 reinforcement that is not so liable to tear at the crease line as the other form.

By forming the curved lock receiving ineision 20 as shown in Fig. 9 it has been found that the lock is more readily guided into position when the end wall is moved toward the side wall and that the normal tension of the hook lock is to permanently seat itself therein. I t also requires no extra time nor effort to press the locking point into or out of position.

From the foregoing ldescription itis evident that with a box uconstructed according to and embodying the present form of folded the lockaccidentally becoming released, and in view of the fact that the staple securing flap is rigidly heldin place no great strain is thrown upon the lock when the box is set up. Itis also apparent that with a box construct- "corner and lock, that there is less liability of invention that there is practically no WasteV of material. I

What is Claimed 15:; l. A tray box made from a single'sheet `of material and scored to provide side and end Walls, one of such walls being provided with a. diago-nally creased corner flap to provide a supplemental attaching `flap, a locking hook carried by'the other Wall, a receptacle for the locking' hook carried by the corner flap carrying Wall, and means for permanently securing the supplemental flap to the hook carrying Wall.

2. A tray box made from a single sheet of material and scored to provide side and end;

walls, one of such walls being provided with a diagonallyA creased corner flap having a supplemental attaching flap, a locking hook carried by the other- Wall, a receptacle for the locking hook carried by the corner flap carried Wall, and fastening device for securing the supplemental flap to the other Wall.

. 3. AA tray box made from a single sheet of l material'and scored to provide side and end Walls, a corner flap formed upon one end of one of the walls and pro-vided With a supplemental flap, means for permanently securing the supplemental flap to the other Wallv` said Acorner iiap being folded diago nally to permit one Wall to be `folded inwardly upon the body otv the box and the other Wall to be simultaneously extended outwardlyj and cooperating locking means carried by the .corner flap and the other wall.

4. A tray box made from a single sheet of material and scored to provide side'and end Walls, a corner flap formed upon one end of one of the Walls andtprovided WithI a supplemental Hap, means for permanently securing the supplemental flap to the other Wall, said corner flap being folded diagonallyto permit one Wall to be folded inwardly upon the body of the box and the other Wall to be simultaneously extended outwardly, a loclc,

ing hook carried bythe other Wall,l and a operation with the Wall carrying the corner flap, asupplemental flap formed upon the corner flap by the severing of the locking hook, and means for permanently attaching the supplemental Hap to the locking hook carrying Wall. A

6. A tray box made from asingle sheet of material and scored to provide side vand end Walls, each corner of the sheet being folded diagonally `from the corner of the main portion and cut to pro-vide" a triangular ap whose base is the diagonal fold, and a locking flap, Whose base is the fold or score line ofcne of the walls, the triangular iiap being disposed to tit coextensively'with the Wall carrying the locking' hook, and its carrying Wall being pro-vided with a slit to receive the locking hook when the box isl set up, and

a permanent fastener for securing the. triangular Hap tol such mentioned Wall.

In testimony whereof I affix my signature.`
