RIVER FOREST, ILLINOIS, ASSIGNOR TO BE CORPORA- TION OF mRICA, OI CHICAGO, ILLINOIS, A. CORPORATION OF DELAWARE EBAY Applicetlon filed November 22, 1980. Ierial No. 487,400. r

The invention relates to trays we: of paper, paper board or like flexible moteriel, particularly adapted for holding bread and similer edible products. The object of the invention is to provide e simple tray which moy be mennfectured etlow cost, and which may be shipped flat in a collapsed condition, and which, when orrived st its destination, may M readily set up to receive the desired article, such as e loaf of breed.

According to the preferred embodiment of my invention, the trey may be formed from a single blenk, which may be readily formed into a box or trey adapted to be shipped list, end wbicli may be set up by merely pushing inwardly on the end wells,

thereby opening up the side wells, whereupon locking reps, preferably formed integral with the end walls, ere folded inwardly over the end walls, thereby holding the box in' assembled or set up position. The loclrin flaps are readily opereted by a simple folding oration, and firmly hold the box in assemled position without the necessity for fitting tabs into slots, or the employment of complicated fastening means, end may be as resdily opened 11 to again ermit collapsing of the trey. lhe collapsing operation is mode possible by dingo-eel scoring of the end ilaps. ".lhe locking flops, when inlolded, brece the end flops to bending along diegonel lines, but :93 the locking ilops are opened up, bracin efiect is removed end the box may then be collapsed elong the lines of weakness. t llhile according to the herein disclosed embodiment of the invention, the ends oi": the tray are diagonally scored and the loosing dens applied thereto, it obvious that s similer errengement might be applied to the sides oi the trey. Accordingly, in the present specification it will be understood thet the terms ends end sides mey be interchanged one for the other, es referring to opposite wells of the trey.

The invention will be more readily understood by reference to the accompanying drawing and the following detailed description Isettin forth an illustrative embodlment, it being understood that the'detalls may be varied without departing from the spirit of the invention,

In the drawing, 7 Fig. l is o perspective View of the trey showing one looking flap folded in place to hold the tray in assembled position and shipped e trey mey be formed from paper, paper boord, or other suitable flexible mote rial, end is preferably manufactured from a single blank which may be cut away in one stamping operation and suitably mored to provide him ed flaps by means of which the blank may be assembled into the form of a tray. The blank is shown i'ragmentarily in Fig. 2 and since both ends of the troy ere alike, one end only is shown in the figure.

The blank comprises a bottom portion 10 having sides 11 hinged thereto alon fiexi ble lines l2. Ends 13 tire hinged to t e bottom portion elong flexible lines M, these ends being provided with side extensions or tleps 15, which are adopted to be folded inwardly along lines it end posted to the sides ll when the box is assembled. The flaps 15 are preferably separated Lironi the sides ll by sniteble cut-sway portions ll, herein shown as stroight at the edges of the sides ll end es fiering at the edges of the flaps 15. The purpose or" the out-sway portions is to facilitate folding and essembling of the box. Extending beyond the ends 13 ere locking dope 18, preferably of the some till Mill

ill

inner ends of the slits diagonal score lines 21 extend outwardly to oints 24, where the score lines 12 and 14 m. The purpose of the diagonal slits 20 and score lines 21 is to facilitate collapsing of the tray, as will be ap arent hereinaiter.

To form t e blank into a tray or box, the sides 11 are folded upwardly alon the score lines 12, the ends 18 are folds upwardly along the lines id and s 15 are folded inwardly eionr lines 13. the he s 15 are then glued to t e sides 11, as clear y indicated in m 1.

The box may be collapsed for shipment in the form shown in Fi 8. The cells sing is accomplished by pressing the ends 1 outwardly, causin the triangular port ons 22 thereof to fo inwardly alon diagonal lines 21, the triangular rtions 'n sepa! rated from the remain er of the en flaps alon the slits 20. Folding the ends 18 outwar y draws the sides 11 inwardly by reason of the connection between the two through the lued flaps-15. The locking fla s 18 may either folded outwardly as in icated at the rightin Fig. 3, or fo ded over the ends 13 mclndin the trian lar portions 22, as indicated at t e left in Eng. 8.

Obviously the containers may be shipped in large quantities and occupy a minimum of space when collapsed in the manner shown in Fi 3. When the trays have arrived at their destination they may be assembled for use by merely pressing upwardly and inwardly on the end walls 18, forcing the side walls 11 outwardly. The tra maythen be locked in assembled position y folding the flaps 18 inwardly so as to overlap the ends 13, covering the diagonal slits 20 and score line 21, thus preventing collapsing along these weakened lines. It will be noted that the locking flap 18 extends the full length and width of the end 13, so that a reinforcement along its entire area is provided. The

fla s 18 fit in position, and due to the added th ckness caused by the glued fia s 15, a sli ht outward pressure is exerts on the sid es of the box. Thus when once the flaps 18 have been folded into locking position, there is no tendency for them to again fly open, althou h they may be readily opened manually. onse uently no tabs and slots are required in or er to retain the parts in assembled relation. A loaf of bread or other like article may now be readily inserted within the tray. I t

The locking flaps 18 constitute one of the important features of the invention. They are preferably of such dimensions as to frictionally engage both the sides and bottom of the container, when infolded in lockin osition. This frictional en agement is en cient to retain the flaps in e locking position and to maintain the container upright until the locking flaps are manually released.

The frictional engagement with the side walls of the container is increased by the added thickness of the glued ilaps 15.

While in the above described embodiment of the invention the diagonal score lines are provided in the ends 13 and the locking ape are provided as extensions thereof, it

is obvious that a similar arran ement could' side walls, diagonal score lines extending from the ends of the lines of juncture beitweenthe bottom and ends partially across the end walls, and diagonal slits extending from the ends of the score lines outwardly to the edges of the end walls, whereby the tray may be collapsed along the diagonal score lines by pressing outwardly on the end flaps, and means for locking the tray in upright position comprising locking flaps hmgedly connected to the end walls and of equal length and width with the end walls, Said locking flaps when infolded completely overlapping the scored and slitted ortions of the end walls and serving to rein orce the same, to prevent colla wing and at the same time preventing infol ing of the side walls.
