Be it known that I, EDWARD O. 'lmsmwr, e citizen of the United' States, reeidiugg m -Brooklyn, in the county of Kings tote o of New York, have invented cert-em new and useful Improvements in Joint Stifienem for Folding Conteihem'of which the following'is a specification.

My present improvement relates to a new form of joint stifienin means for preventing the collapse of 01 ing, scored, oints in foldable paste board display containers where scoring is used for predeterminingthe folding points in permitting said container or its component parts to be folded flet.

While my invention is hereih shown in connection with display oontainers, it is noted thatthe invention as claimed is not limited in its use m couteineie ,nor to (115- Another object of my invention is to make such stiffening means integral with the box thereby obviating the necessity of providing 21. separate moons therefor, and at the some 25 time to provide that such a, ilevicehe ve quickly set into and out. of operative posltion. 7

la the drawing spective view 0 herewith, Fig. 'l. is a perecontainer showing the improvement thereon.

Fig. 2 is a. sectional view, slightly enlarged, taken on the line Ab, Fig. 1, looking in the direction of the arrow.

Fig. 3 is a. rear View of said container showing the easel or support portion partly folded. y Fig. l is a. sectional view taken on the line 4-4, Fig. 2, looking in the direction of the arrow. 7

Fig. 5 is a. sectional view taken on the line 5--5, Fig. 4, looking in the direction of the arrow.

. While in Fig. 1, I have shown my etifieningdevice located upon an easel or tilting bottom of a cello, sing or folclehle container generally demo by 2, it is obvious that other euch joimtures es meyhe found to reis of the coed eeeel or tilting ty ole portion 1, which is integrally attached. to the displa. hohteiner, wherciii the container is provi ed with a. lololihg or collapsing easel portion-1, usually cl with a. portion of the hoxstructure, more -emlly foldable against the box stmcture in order to make it as neerly rectangular es phle,

so as to economize in shipping space, as is well known in the customary practice.

However, in conteihers of the type herein disclosed the weight of the m. carried or shipped therein is such tot the portion 1, wheuo encd' out, and the conteiner, placed in fispley position, for exposing the floods, may collapse under the weight of a. ll container thereby defeating the purpose for which the eceel portion 1 was designed.

Usually the collapse of the easel in Mente'iiier of this cleee is also clue to the foot that the scoring, indicated by the dotted lines 3 throughout the drawings herein, may

be rather deeply dome, and thus-weaken the easel or supporting sections. In other instances, cornstent folding and opeiii of the easel portion 1 may further wealzen t e scoringeo that its inherent stifiness' is destroyed and the easel portion will then tend to remain in its folding position rather than in the extended and supporting position as shown in Fig. l.

I have "found in practice that while the K easel portion 1 may be folded in a number of places that there is generally one or more positions out of the plurality of scoring points that may he provided with a stifi'ening means without the necessity of having every scored point provided. In the present instance, I have found that the folding points 4, Fig. 3, formed et one of the scoring oints ,3 when roperly provided with sti' cuing means, will permit the wool to he set up to support any reasonable couditiczc of load, and incidentally permit of a. very large numher'ozl conse uerit collapsing and extending actions wit out undesirolole collopse occurring when the box is set up for. zlieploy.

My improved stifiemihg moons coins in to the line of the provision, treusvorsely scoring, of e bendable hinged, tab or lug '8, Ereterehly of eemi-ciiwuler form, which is looked out of the well of the side upon which the ecoring occurs. lo the petitistance the tel) member ie preterehlye with ltS largest diet/er 1 EN? m lllll to its associated side at a point'i, Fig. 5, so that in efiect, when thistab is bent at a right angle to its inoperative position, it acts to bridge the scored line and thereby stidens the scored member.

Naturally, in the process of manufacture, the cutting of the stifiener into the side wall and transversely to the scored line 3, as above noted, also permits the stidener element to become itself scored so as to permit ready folding at the scored joint when the stidener is in non-operative position, as is disclosed at a, Fig. 3,wherein the easel portion is shown partly collapsed against the bottom of the box 2 When the easel portion as shown in Fig. 3, is fully extended as in Fig l, the stidener member lies in the plane of the wall and partakes of the extending action of its associated wallsection, and after the easel portion 1 is extended into support position, then the stifiener element 6 is pushed inwardly by the finger thereby causing it to take the position as shown 1n Fig. 5, and, owin to the substantially right angle, sheltike projection of the tab 6, across the line of scoring 3, the said scoring is prevented from being bent inwardly or outwardly, due to the transverse truss action caused by the re-argement of the tab 6 at right angles to the sides of the said easel ortion 1 and transverse to theline of scormg 3.

It is obvious that various geometric forms of tabs may be out in the box without despirit of the disclosure made herein, and it is also obvious that, while l have shown the stifi'ener-tab as being integral with the side of the box and blanked therefrom, that other modifications may thus be made for the same purpose, all of which l would consider as being equivaparting from the lent of the structure herein disclosed.

What ll claim is: i. lna device ot the character described,

, a member provided with a, line of told, and

a partially cut-out stiii ening means disposed transverse to said line, said difiening means being bendable upon a score line transverse to saidline of told,

2. lin combination, a supporting device;

and asu oitin member rovided with a Lessors scored line out fold, providing relatively foldahle sections; said member being pro= vided with a stifiening means partially out out of both said foldahle sections, said means being scored at, its base portion and being disposable substantially erpendicularto said line to stiffen saidmeinhe 3. A toldab-le display container having a scoredfoldable easel thereon, and a partially cut-out bendable stihening means located transversely to, the line of scoring, the said bendable means having its bending base developed transversely to the line of said scoring.

4. A foldable display container of the class described, having a scored toldable portion and a bendable cut-out tab located" transversely to the line of the scoring upon said foldabl'e portion, said'tab being adapted to be bent at rightangles to the plane of said foldable portion whereby to bridge and prevent inversion of the score on said portion. Y 1

5. in combination, a supported device, and a supporting member provided with a scored line of told providing relatively toldable sections, and a single tab member being cut out of said ioldable sections on both sides of the fold line thereof, the'said tab being provided with a score line at its base and transverse to the said told lines, and being bendable at right angles to the said told line whereby to hold said foldable sections against inversion.

6. A toldin' support for boxes oi? the class describes. comprising a section of said box being'bendable to cause said support to lie flat to the box when in closed position and provided with a partially cut out tab portion for a single score at itsb portion, the said score being formed at right angles to the line of scoring between sections at said folding mrtion whereby when said tab v is bent upon said score line, it forms an unscored bridge portion located in such posi tion as to prevent inversion of said i ldable portion when the tab is bent .at rightangles to the plane of said folding rtion.
