BOX-BLANK.

` Specification of Letters Patent. Patented NOV. 23, 1920.

Application led April 12, 1920. Serial No. 373,197.

To all whom may concern.'

Be it known that I, JESSE Snom, of Cincinnati in the county of Hamilton and State of hio, have invented certain new and useful Improvements in Box-Blanks5 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.

The industry of making cardboard boxes is being seriously retarded at this time because of the shortage of paper stock. In consequence it is necessary to effect as much saving of material as possible in the manufacture of cardboard containers.

My present invention has this object in View. Primarily it relates to candy boxes and contemplates improving the formation and assembling of the receptacles.

In the drawings, Figure l shows the box blank flat. Figs. 2, 3, l and 5 show the successive steps of folding and locking the parts at one end. Fig. 6 is a perspective of the bon with its trays and candy, and Fig. 7 shows one of the trays.

I have shown the blank formed with flaps l, 2, 3, at each of its end edges and cut at the lines 4 between the flaps. The blank is scored at the `lines 5. Flaps 3 are each shown formed with a tongue 6 by cutting the flap on a substantially semi-circular line.

The flaps 2 are each scored at the lines 7, 8, and cut to form a slot 9 at about the center of line 8. This slot is U-shaped at its center to form a lip 9a.

The blank being folded on the side lines 5 the end flaps are manipulated as in Fig. 2,

. flap 3 being first turned inward, its tongue 6 having been bent to protrude slightly inward. Flap l is then bent over the outer face of ldap 3, and liap 2 is bent upward as in Fig. 3 over the outer face of flap l. As seen in Fig. 4, the flap 2 is bent on the scored lines 7 and 8 so that the body portion of the flap may contact with the outer surface of flap l while its free edge is passed downward beneath tongue 6. The margin of the tongue 6 then enters slot 9, being Iguided by lip 9a, the slot readily opening because of its lying in the scored line 8 on which flap 2 is bent as it is turned inward. Fig. 5 shows the flaps fully closed and united, withthe edge of `iap 2 extending fully to the base of tongue 6 and over the inner face of flap 3 at each side of the tongue and with the tongue inserted in the slot and held by lip 91L pressing against its inner face, thus securely locking the parts.

It will be noted that there are no projecting surfaces, especially no upwardly pro-- truding parts. Consequently a cover made in the manner described may be placed over the box without encountering any resistance. It will be especially noted by those skilled in the art that I effect a substantial saving in material as compared with the commercial hardware box as receptacles of this character are known.

. In Figs. 6 and 7 I have shown the box con taining trays l0. As seen in Fig. each tray is of width greater than the box and is scored longitudinally on the four lines 12. Intermediate the outer pairs of lines the blank is cut to form a series of round holes 13. rI he material is bent upward between these lines causing the surfaces 14 between the holes to bend. In this formationthe tray fits snugly within the box and its ridges 15 comprise a pair of racks having circular notches to receive sticks of candy 16. The candy units are kept separated and the tray has just enough resiliency to allow of its yielding when jarred without breaking the candy sticks.` The filled box will of course contain a series of superposed trays.

I claim as my invention:

A box blank having end flaps on its sides and bottom, one of said' side flaps being folded inside the other, said inner flap having an upward projecting tongue, said bottom flap being scored on two transverse lines near its free edge and having a slot in the outer of saidscored lines, said slot forming a U-shaped lip, said flap being adapted to be lfolded over the upper edges of said side flaps and to receive said tongue in its slot, said lip acting as a guide for said tongue and lying against the inner face thereof.

In testimony whereof I have signed this specification.

JESSE SROFE.
