2 Claims.

Thisf invention relates to trays and I'boxes.

The'primarymbjectofthe invention iswto provide atray or` box-for the. handling of merchandise, particularly inA bakeries-for thedelivery of bread, cake.. doughnuts; cookies and the like bakeryy products,l and which -boxis light; easy` to handle and .to stack rand issanitary.

Thefeatures of our invention :are:

A" light'.skeletonv frame: and i a liningA of= nbreboard or. thelikerheld in the skeleton frame so asrto be easily* replaceable"` and thus.` combining lightness, durability and facility toikeep the: tray in sanitary condition; a light lining preferably ofbreboa-rd which canbestored and 'shipped in collapsed-atfpositioniand' which can vbe extended to fit into the frame of the tray so as to be prevented'from collapsing while in use; a rim or top edge structure which has a limited resiliencyjand which provides a' projection for engagementwith the top edges ofthe sides of the lining .orjremovable` walls;y integralelements on the skeleton frame to facilitate interlocking and stacking; easy adaptation for'various usesr and retaining the facility of'replacing of the inserts;

We are awarethat'some changes may be made in the general arrangements andcombinations. of the several'devices andparts,' aswellga's-V in the details ofthe constructionthereof withoutdeparting from thescope ofthe present invention as set' forth in thefollowing speci'cationandas frame of the tray constructed in accordance with our invention.

Fig. 8 isa liragmental sectional vievvof the tray viewing =a corner thereofl In carrying out our invention we make use of a skeleton frame I and a light andi disposable insert 2.

The skeleton frame; in theA form illustrated in Fig. 1, is particularly adapted: for use as a bread box, arrditincludesvhorizontal*bottom pieces 3. Each bottom pieceA 3f is of substantially. angle constructionso as toprovde a bottomvlange 4 and an upright side-flanged. 'lhese bottom pieces are suitably secured, preferably by spot Welding, to the lower ends of vertical corner-'bars 1. Each vof these corner bars i" is preferably of angle around-'a wire orl rod II; which latter is formed into a rectangular shape parallel with the rec- "ta-ngular shape'dened by the bottom pieces 3. lThe strip offsheet metalthus forms aV tubular wrappinglz around said `wire l I, and it also forms a skirt I3 which extends downwardly from said tubular wrapping I2 and is preferably spot welded to the top portions of the vertical corner bars 1. The rim thus formed 'by the tubular wrapping I2 and the Wire II overhangs or overlaps inwardly of the basket to form a ledge I4 projecting over and above the bottom anges 4 of the respective bottom pieces 3. The insert 2 is pressed under said ledge I4 and is maintained in its upright position.

At each end of the cross bar 9 extends upwardly a vertical brace I6 between the upright flange 6 and the skirt I3.

The skirt I3 at the middle of each end of the tray is folded under inwardly so as to form a rounded grip I1 for the handling of the tray. At each end of the grip I'I is a vertical thumb brace I3 between the respective upright anges 6 and portion of the skirt I3.

The cross bar 9, the brace I6 and thumb braces I8 are formed of the cross section shown in Fig. 3, namely are 'dished so as to form a rib I9 outwardly of the tray thereby to increase the rigidity of the brace.

The insert 2 is preferably made of fbreboard. It includes a bottom 2|. At the longitudinal edges 22 of the bottom are side flaps 23 which are foldable up into the position shown in Fig. 4. At each end edge 24 of the insert bottom 2l is an end iiap 26 which is foldable up into the upright position between the ends of the side flaps 23. Each end ap 26 is cut away at the middle of its top edge to form a grip recess 21 which is located opposite the grip I1 at the end of the tray l. The insert is stored in a flat position, namely the end flaps 26 are folded over the bottom 2l and then the side flaps 23 are folded inwardly. This folded flap is placed into the tray so that the insert 2| rests upon the bottom flanges 4. Then the side flaps 23 and end flaps 26 are unfolded and pressed under the respective ledges I4 to be held in place. The height of the side aps 23 and end flaps 26 is such that they t tightly or snugly between the bottom flange 4 and the adjacent ledge I4. Thus the ledge I4 effectively holds the insert 2 in place when an empty tray is turned upside down, or when in handling a full tray upward pressure is applied to the bottom 4.

For facilitating stacking of the trays, We illustrate in Figs. 1, 5, 6 and 7 the use of generally triangular corner projections 28 at each corner of the tray I. These projections are formed by a generally triangular hollow boss with outwardly extended flanges 29 at each edge thereof which latter are welded to the underside of the bottom flanges 4 at each corner of the tray. The triangular corner projections 28 are so arranged that the right angle sides thereof are spaced inwardly from and parallel with the adjacent sides at the corner of the tray so that when a tray is superimposed upon another, then the corner projections 28 fit into the corners of the top section of the lower tray and prevent the accidental sliding of one tray olf the other.

Another form of stacking projection is illustrated in Fig. 2 and is in the form of ribs 3l pressed downwardly out of the bottom fianges 4 all around the tray I.

We claim:

l. A tray of the character described comprising a base frame, generally vertical corner post members extended from the base frame, a top frame on the tops of said vertical corner post members, a disposable lining fitting into the area dened by said frames, and a generally cylindrical solid rim element on said top frame projecting inwardly of the tray and above the adjacent edges of the lining, said lining including a bottom and sides foldable from a collapsed position over said bottom to an upright position between said base frame and said rim, the spacing between the base frame and said rim being such as to snugly receive said sides of the lining therebetween so as to hold said sides in upright position.

2. A tray of the character described comprising a base frame, generally vertical corner post members extended from the base frame, a top frame on the tops of said vertical corner post members, a disposable lining fitting into the area defined by said frames, and a continuous retaining rim element all around said top frame, said lining including a bottom and sides foldable from a collapsed position over said bottom to an upright position between said base frame and said rim element, said rim element extending inwardly of said tray overlying the top edges of said lining sides and being spaced from said base frame to such an extent as to snugly receive said lining sides therebetween so as to hold said lining sides in upright position, the lining sides at two opposite sides of the tray having handle recesses at their tops, and upright handle braces between the bottom frame and the top frame adjacent each side of said recesses spaced to serve as thumb rests.
