GEORGE S. PIGKELL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO J. THOMAS STAVELY, OF SAME PLACE.

PAPER BOX.

SPECIFICATION forming part of Letters Patent No. 246,813, dated September 6, 1881.

(No model.)

To all whom it may concern:

Be it known that I, GEORGE S. PIGKELL, a citizen of the United States, residing inPhila delphia, Pennsylvania, have invented an Improvement in Paper Boxes, of which the following is a specification.

My invention relates to an improvement in what are known as knock down paper boxes-that is to say, boxes which are flattened out for transportation orstorage, but which can be readily made into box form when they have to be filled. The object of my invention is to provide for the secure fastening of the lockingflaps of such a paper box.

In the accompanying drawings, Figure 1 is a View of the blank from which my improved box is made; Fig. 2, aperspective view of the end of the box, showing the method of locking the flaps together; Fig. 3, a view showing the flaps locked, and Fig. 4 a view showing a modification.

The body of the box comprises the four sides, A A B B, and the pasting-flap l), and the ends of the box comprise the inner or closing flaps, a a, and the outer or looking fiaps,b b, the flaps a a forming continuations ot'the sides A A of the body, and the flaps b b forming eontinuations of the sides B B of the same, the blank being scored on the linesw and y, in order that it may be readily folded into box form. In each flap b, parallel with and adjacent to the line of fold 1, are two incisions, d, and the outer portion of each flap b is cut away, so as to form a T-shaped end, e, thereon, the pro-, 35 jections f of said end being adapted to enter .the incisions (Z of the flaps b in looking the flaps together, as shown in Fig. 2, so that when the flaps are locked, as in Fig. 3, they will effectually resist any tendency to open the box by pressure from the inside, sneh tendency being resisted by both projections fof' the T-head ve of the flap, the strain being directly in line with these projections, and tending to lock them more securely to the flaps I). The box can be readily opened from the outside, how- 5 ever, by simply elevating the outer edge of the flap I) and moving the same in a direction the opposite of that indicated by the arrow in Fig. 2. I

In Fig. 4 I have shown a inoditicationot' my invention, in which the flap b has but a single hook. c, with projection f adapted to a single incision, d, in the flap 1). This construction may be adopted in boxes the contents of which are light and not calculated to exert much 5 strain upon the flaps.

I claim as my invention- The combination, in a paper box, of the body comprising the sides A A and B B, the endclosing flaps a a, and the locking-flaps b b, each flap b havii'ig an incision or incisions, 6?, parallel with and adjacent to its line of fold y, and a side of the portionot the flap covered by the stem of the head 0, and each flap Z) having a hook or hooks,f, adapted to enter said in- 65 cision and lock the flap I) to the flap I), as set" forth.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses. GEORGE S. PIOKELL. Witnesses:

HARRY DRURY, HARRY SMITH.
