Propst, Ann Arbor, Mich., assignor to Herman Miller Inc., Zeeland, Mich., a corporation of Michigan Filed June 10, 1968, Ser. No. 735,801 Int. Cl. B65d 21/00 US. Cl. 211-126 11 Claims ABSTRACT OF THE DISCLOSURE The disclosure relates to an article handling tray with an open top and an open front for top loading and front dispensing. The tray is formed of a back wall, two oppositely disposed side walls, and a bottom. A stiffening and gripping rim extends around the top of the 'back and side walls, downwardly along the front of the side walls, and across the front edge of the bottom. In one embodiment, the tray is an open mesh structure and the rim is attached to the top of the back and the front of the bottom thereby leaving a free gripping area at the top and front of the sides. In another embodiment, the tray is integrally formed from a plastic material. Preferably, the stifiening and gripping rim has an outwardly extending portion at the back of the side wall to permit the trays to be used asdrawers with the gripping rim engaging rails in a cabinet or the like.

This invention relates to article handling trays.

It is an object of this invention to provide an article handling tray for linens and the like which is easily loaded and unloaded.

It is a further object of this invention to provide an article handling tray with integrally formed grips for easy handling.

It is a further object of this invention to provide an article handling tray which is nestable so that the trays can be transferred in a minimum amount of space.

It is yet another object of this invention to provide an article handling tray which can be used as a drawer, and which article handling tray has a means to prevent inadvertent removal of the tray from the drawer.

It is another object of this invention to provide a sturdy and easily washable tray for linens and the like.

Other aspects, objects, and the several advantages of this invention are apparent to one skilled in the art from a study of this disclosure, the drawings, and the appended claims.

According to the invention, a nestable tray has an open top and open front. The tray is formed from a pair of side walls, a back wall, and a bottom which are joined together to form the tray. The side walls, and preferably the back wall, slant inwardly and downwardly to permit nesting of empty trays for storage and transportation. A continuous stiffening and gripping rim extends throughout the open top and front of the tray. Preferably, the stiffening and gripping rim extends outwardly of the side walls at least at a back portion thereof to provide a means for supporting the tray in a rail in a cabinet, for example. Stop means are also provided on the stiffening and gripping rim for preventing inadvertent removal of the tray from the cabinet.

In one embodiment, the tray is made in an open mesh structure to facilitate washing, and the stifiening and gripping rim is attached to the tray at the top of the back wall and at the front of the bottom to leave a free gripping area at the top and front of the side walls.

In another embodiment, the tray is integrally formed from plastic material.

The invention will now be described with reference to the accompanying drawings in which:

Patented June 30, 1970 FIG. 1 is a perspective view of a first embodiment of the invention;

FIG. 2 is a top view of the tray shown in FIG. 1, illustrating how the tray can be used as a drawer;

FIG. 3 is a front elevational view of the tray shown in FIGS. 1 and 2;

FIG. 4 is a side elevational view of the tray shown in FIGS. 1 through 3;

FIG. 5 is a perspective view of a second embodiment of the invention; and

FIG. 6 is a side elevational view similar to FIG. 4, showing a plurality of trays in nesting position.

Referring now to the drawings and to FIGS. 1 through 4 in particular, an article handling tray 12 is shown with sides 16 and 18, a back 20, and a bottom 22. In FIG. 1, the tray 12 has linen 14 stacked within it. As can be seen from the drawings, the tray has an open top and open front so that the linen 14 can be easily removed and easily stacked within the tray.

In the first embodiment shown, the tray is formed with an open mesh structure. The side walls 16 and 18 are formed by a plurality of parallel U-shaped wires 24 which extend across the bottom 22 of the tray. The back wall 20 is formed from a plurality of parallel L-shaped wires 28 which extend downwardly and across the bottom. The L-shaped wires and the U-shaped wires are joined at the bottom. A rim wire 26 extends around the sides and back of the tray. This rim wire 26 is attached to the U-shaped wires 24 at the top portion thereof and is attached to the L-shaped wires 28 at a top portion thereof.

A top rim 30 is provided for gripping and rigidifying the tray structure. The top rim 30 extends around the back wall, the top of the side walls, down the front of the side walls, and across the front of the tray. Thus, the top rim 30 has a back portion 32 which joins forwardly extending side portion 34. The side portions extend inwardly at 36 and then forwardly again at 38. Thus, at the side walls, the top rim 30 extends outwardly of the plane of the side wall so that the tray can be supported on rails such as 48 in a cabinet such as 46. These forwardly extending side portions 34 extend outwardly further than the forwardly extending portions 38 so that a stop can be provided at 36 to permit the tray to be retained Within a cabinet structure as illustrated in FIG. 2 In this way, accidental removal of the tray from the drawer can be prevented. The rim extends inwardly again at 40, downwardly at 42, and across the front at 44.

As illustrated in FIG. 4, the back Wall 20 slopes downwardly and slightly inwardly. As seen in FIG. 3, the side walls 16 and 18 also slant downwardly and slightly inwardly.

As can be seen from FIG. 6, the structure of the tray provides an efficient stacking with each subsequent tray on the stack positioned upwardly and forwardly of the lower tray by a distance equal to the thickness of the rim 30. The trays, however, have a box-like appearance, with very little space lost in slanting walls.

Referring now to FIG. 5, an integrally molded plastic tray 50 is provided with opposite sides 52 and 54, a back 5 6, and a bottom 58. Holes 60' are provided in the side wall for drainage so that the tray can be easily washed.

An outwardly extendingrim 62 is provided to surround the open areas of the tray. This rim provides a gripping area for carrying the tray and permits the tray to be used as a drawer in the same manner as has been show in FIG. 2.

The outwardly extending rim '62 has a back portion 64 which joins the forwardly extending side wall portions 66. The side walls extend inwardly at 68 and then forwardly at 70. The rim extends inwardly again at 72, downwardly at "74, and across the front at 76.

The side Walls 52 and 54 slant inwardly in the same manner as has been shown for the first embodiment of FIGS. 1 through 4. Preferably, the back wall 56 also slants inwardly as the baok 20 of the tray 12. In this manner, the tray shown in FIG. 5 will stack in the same manner as the tray shown in FIGS. 1 through 4.

It will be appreciated from viewing FIG. 6, that the open mesh tray of the invention can be formed with vertical side walls without losing the compact nesting qualities. With vertical side walls, the rim 26 can be eliminated and the upstanding legs of the U-shaped members 24 will be aligned in a plane parallel to the side walls when the tray is nesting. To provide added strength, the top of at least some of the U-shaped members 24 can extend to and can be fixed to the gripping rim portion 38 in the same fashion as the L-shaped members 28 are fixed to the rim portion 32.
