' Application filed May 27, 1924. Serial No. 716,275.

7 '0 all whom, it may concern Be 'it known that I, GONZALO -ANo1RA GARCIA, a Mexican citizen,,residing at San Antonio, in the county of Bexar and State of Texas, have invented certain new and useful Improvements'in Folding Containers,

, of which the following is a specification.

This invention relates to folding containers or boxes, and more particularly to fastening means therefor.

An object of the invention is to provide a folding paste-board box adapted to be closed in such a'mannerthat it cannot be opened without detection.

A further object of the invention is the provision of a box having flaps adaptedto be interlocked whereby the box may be securely closed without the use of glue, fastening elements, or the'like.

A further object of the invention .is the provision of a blank having the above men-' tioned characteristics with an attendant saving of material. v

In the accompanying drawings, I have shown one embodiment of the invention. In this showing:

Figure 1 is a plan view of the blank,

Figure 2 is a perspective View of one end of the blank in the process of folding.

Figure 3 is a similar view showing the folding more nearly completed,and,

Fi ure 4 is a similar view showing the l 0 0 box 1n closed posltlon.

Referring to the drawings, the reference numeral 1 designates the sides of ,the box and 2 the end wallsh One of the end walls is provided with a side flap 3, adapted to be secured totheifree end of one of the sides'in assembling the box by means of adhesive. As shown, the blank is provided with scorings or perforations 4, extending transversely thereof to permit proper folding of the side and end walls. The side walls are provided with flaps 5 at the top and bottom and the end walls are similarly provided with flaps 6. At the point where the flaps join the body, the blank is provided with scorings or perforations 7.

The flaps 6' are provided with substantially triangular recesses'8 on one of their.

side edges, the recess of one flap being. formed on the op osite side from the recess of the opposite -ap whereby each of the recesses A gwill face the same side of the box when the box is in folded position. The side flap 5.

between the end flaps 6 is provided with triangular recesses 9 at each end and the other side flap 1s prov ded with an irregular recess at its outer edge. As shown, tlns recess is formed by cutting inwardly at-an' angle,

forming the inner side 10 of the recess, the bottom of the recess being at a point from the edge of the flap substantially .equal'to the depth of the recesses 8 and 9. The .flap is then out along the line 11 parallel to its outer edge and then cut diagonally along the line 12 for a short distance. From the line '12, the flap is cut substantially parallel to theside wall of the flap, as at 13, forming a tab-14.

In assembling the box, it is first folded alon the perforated lines or scorings 4 and the aps bent over along the perforated lines or scorings 7. Theflap 6 of the end wall 2 between the two side walls is then extended over the endflap 5, entering the recess'in its outer face. The pointed wing of the flap 6 formed by the recess 8 is inserted under the flap with the bottom of the recess 8 coin-. ciding with the meeting point of the edges 10 and 11. The flap 6 is then locked in position. The flap 5 of the other side is the folded over the gfirst flap 5 and the flap 6 an the wings of the recesses .9 inserted beneath the first flap 5. The bottom of each of the recesses 9 will coincide with the points formed by the meeting edges 10 and 11, and 11 and 12 respectively.

The other end flap e is then folded under y the adjacent end of theadjacent flap 5, and the tab 14 of the first flap 5 is then lnserted beneath the other flap 5 along the line 13 at the bottom of the recess 9.

When the box is folded in this manner it cannot be opened without tearing one of the flaps'or cutting one of the scored lines 4 or 7. Directions may be given to open'the box along one of the scored lines 4.

It is to be understood that the form of my invention herewith shown and described is to' be taken as a preferred example of the same, and that'varidus changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined, claims.

I claim:

1. A folding box formed of a blank comprising side and end walls, and flaps connected to said walls, each ofthe flaps .hav-

ing a recess forming a. projecting tab, the

tab of each flap'bemg adapted to engage with the body was of the adjacent flap and the tab of the flap which is located at one end of the blank being adapted to be inserted in folded position underneath the flap of the other end of the blank and to become unfolded inside of the box, and interlocking the intermediate flaps between them.

2. A folding box formed of a blank comrising side: and end walls, and foldable aps connected-to said walls, each of the v f'flaps being provided with a recess forming a projectin tab, the space between the upper face one flap and the lower face of another being ada ted to receive the body interior of the box when the folded tab is released from its folded position to interlock with the tab of the o posite flap.

4 3; A folding box forme of a blank scored into sections so as to form side and end walls, and flaps connected to said walls, the

'ing projecting tabs, the deepest point; of the incision of the first flolded flap substantially intersecting the deepest point of the incision ofthe next flap, these two flaps forming a, space between the upper face of one flap and the lower face of the other adapted to receive and interlock the "tab of the next flap, and these folded flaps forming another space ada ted to receive the body portion of the fina 1y folded flap, the tab of said flap being initially arranged in folded position and being adapted when inserted to unfold inside of the box and to engage the tab of the opposite flap, preventing disengagement of the flaps. i In testimony whereof, I aflix my signature.
