CONTAINER.

Specification of Letters Patent.

Patented Mar. 22,1921.

Application filed February 21, 1919. Serial No. 278,335.

To all whom it may concern:

Be it known that I, FRANK B. DAVIDSON, a citizen of the United States, residing at Marseilles, in the county of La Salle and State of Illinois, have invented new and u seful Improvements in Containers, fof which the following is a specification.

`This invention relates to foldable boxes and-other containers having a portion provided with marginal flaps on the side and front edges thereof, and more particularly to that ortion of the container forming the hinged id or cover thereof.

Among the objects of my invention 1s to connect the Side Aand front marginal iiaps of the lid or cover together at the corners thereof by interfolding parts so that said flaps will be held relatively7 rlgid with re spect to each other and to the box portion of the container, whereby said flaps will avoid striking the box portion in the repeated closing of the cover. Another object of my invention is to provide as a part of the front flap of the cover a structure whereby portions of the front flap will yieldingly bear against the front wall of the box when the cover is closed and thus hold the latter against opening accidentally. l

The invention consists further in the matters hereinafter described and more particw. y larly pointed out in the appended claims.

In the accompanying drawings-- Figure 1 is a erspective view of a box or container having a hinged lid or cover embodying the features of my invention, the lid being shown in partially open position,

Fig. 2 is a bottom plan view of the blank portion of said lid;

Fig. 3 is .a perspective view of the lid, fully open, with the parts forming the marginal flaps around three sides of the lid partially set up Fig. 4 is av perspective view of the hd, fully open, with one corner of it broken away to illustrate the resilient holding feature to be described; and

Figs. 5 and 6 are transverse sectional views, taken on lines 5- and 6, respectively, of Fig. .1.

I The box or container shown in the drawings 1s preferably made of fiber-board or other non-metallic, relatively rigid, but light material, and is formed from a flat' blank so cut and scored that when set up it provides the box with four joined upright walls 1, 2, 3, and 4, the latter having at one corner of the boxa vertical flap 5 secured to the wall 1 by any suitable means, such as metal fasteners 6, as shown. The bottomv of the box is preferably formed of interlocking H aps (not shown) integral with said uprlght walls. The box has a lid or cover 'l'V hinged at its base to the up er edge of the rear wall 4, the Ylid being ormed integral with said rear wall and being a part of the blank of the entire box. Said lid is provided at the sides thereof with marginal flaps 8, 8 extending the full length of the lid, and at the front edge with a marginal flap 9 extending across the lid between the side flaps 8, 8; all of said flaps overlapping the box walls on the out-side thereof when the lid is closed.

In Fig. 2 is shown, spread out flat, that portion of the blank of the box constituting the lid, and it will be noted that the same has a flat rectangular body portion 10, integral at its base with the rear wall 4, such parts being divided by a fold or score line 11, which forms the line of hinge between the lid and said rear wall. The flaps 8, 8 at the opposite sides of the lid are divided from the body portionl() thereof by parallel score or fold lines 12, 12. Each side flap 8 is provided at its forward end with an integral` extension 13, divided from the flap 8 by a score or fold line 14 extending across the flap to the score line 12 and atV right-angles thereto. Said body portion 10 is provided with two integral sections 15, 16 extending across the lid between the extensions 13, 13 and being divided from each other by a score or fold line 17. The section 15 is integral with the body portion 10 and is divided. therefrom by a score or fold line 18 parallel to the score line 17 and at right-angles to the score lines 12 and being in effect va continuation of thescore lines 14, 14, The sections 15, 16 are cut from the corner sections 13, 13 by lines of severance 19 at right-angles to the scorel lines 17, 18 and in alinement with the score lines 12;,the lines of severance extending inward to the score lines 14. The section 16 is provided at a point between its ends, preferably at thecenter.7 with an integral cut-Hardly pro3ecting locking tongue 20 made rigid therewith and adapted to be inserted into a locklng slot 21 cut in the blank of the lid in the score or fold line 18. In the box shown, the corner flaps 13 are of the same size and so are the sections 15 and 16.

In setting up the lid from the blank, the side flaps 8, 8 are bent in the same direction to positions at right-angles to the body 10 on the fold lines 12, 12, and the corner flaps 13, 13 folded inward toward each other on the score lines 111, 14'to bear edgewise against the bod 10 along-thoe score line 18, as shown in Fig. 3. It will be noted that'the opposed ends of the aps 13, 13

terminate short of each other to clear the locking slot 21. When such arts a're so positioned, the section 15 and 1ts connected section 16 are folded toward the flaps or extensions 13, 13 on the score line 18 until the section 15 bears latwise against the outer faces of the flaps 13, 13. Thereupon the section 16 is folded inward toward the bodyportion 10 over the outer edges of the flaps 13, 13 and brought iatwise against the inner faces of said fiaps. The latter are then between the folded sections 15, 16, with the folded edge between said sections forming the outer edge 'of the front flap 9 of sa1d lid. To hold the parts in such folded positions, the locking tongue 2O is inserted into the locking slot 21 and the marginal flaps of the lid locked together relatively rigid and maintained in a relatively xed position with respect to each other and the bodyl ofthe box so as to avoid striking the box in the swinging of the lid into closed position. When the parts are thus folded and locked, it will be noted that the section 15f constitutes the outermost section and the section 16 the innermost section of the forward marginal iap 9, thus making the latter of a double thickness of sheet material, with the result of stifening and strengthening the same. With the flaps 13, 13 folded between said sections 15, 16 and the latter locked to the-body of the lid by the tongue 20, the marginal flaps 8 and 9 are connected together and held from displacement with respect to each other and espe-A cially when any of said flaps are engaged by the hand of a person in opening said lid. The locking tongue 20 bein located at the center of the section 16 an the' corner flaps 13 terminating short of thelock-v mg tongue, the locking slot may be located at the base of the section 15 and said sections brought close together at such dpoint, with the result that the opposite en ortions a, a of the section 16 flare inwar or away from the fla s 13,' as shown in Figs. 4 and 5. From this it follows that said end portions a, a project into the lid a suiiicient distance to cause them to be flexed or pressed toward the flap 13 when the lid is closed, by the front wall of the box, the result being thatl the end portions a, a of said innermost section yieldably bear against the outside face of the front wall 2 to hold the lid from accidental opening after being closed.

In the t pe of box shown, the side and front wal s are provided at their upper edges with inwardly extending marginal flaps 22, which lie beneath the lid when the latter is closed. While I have shown my invention applied to the hinged lid of a box of the kind mentioned, yet it is to be of course understood that my invention may be equally as well used in other parts or portions of foldable containers.

I claim as my invention:

1. A container having a portion made of relatively thick material provided at its side and front edges with marginal flaps, each side flap being provided with an inwardly foldable extension terminating short of the extension on the other side flap, said front flap being formed of two foldable sections overlapping each other with the extensions on sai -side aps therebetween, and the innermost section of said front iap having a locking tongue between the opposed ends of said extensions and insertible in a locking slot at the line of fold dividing the outermost section of said front fla from the body part of said container portlon and located between the opposed ends of said extensions.

2. A container having a box-like body portion and a hinged lid made of relatively thick material, said lid being provided on its side and front edges with .marginal flaps connected together and overlapping the side and front walls ofthe box on the outside thereof when the' lid is closed, said front flap being formed of two overlapping sections, the innermost one being locked at one point with the bodyI of the lid between the ends of said sect-ions so that the end portions of said innermost section project inwardly and bear yieldably against the outer face of the front wall of the box when the lid is closed.

3. A container having a box-like body portion and a hin ed lid made of relatively thick material, sald lid being provided on its side and front edgeswith marginal flaps, each side flap being provided with an inwardly foldable extension at the -front end thereof and terminating short of the exap being formed of two foldable sections overlapping each other with the extensions on said side flaps therebetween, and the innermost section of said -front flap having an integral locking tongue between the oposedends ofsaid extensions and insertible in e locking sloty formed in the lid at the line of fold dividing the outermost `section Blf of said front flap from the bociy portion o said lid and located between the opposed 10 ends' of said extensions.

In testimony that I `eleiin the foregoing as my invention, I affix m signature, this* 18th day of February, A. 1919.

FRANK B. DAVIDSON.
