TRAY FOR MUSHROOM PICKING BOXES Filed July 23, 1965 5 Sheets-Sheet 5 TED L. PAXTON.

INVENTOR. M

ATTORNEY.

United States Patent 3,319,799 TRAY FOR MUSHROOM PICKING BOXES Ted L. Paxton, Riverside, Califi, assignor to Eleanor M. Paxton, Riverside, Calif. Filed July 23, 1965, Ser. No. 474,300 4 Claims. (Cl. 211-126) This invention relates to trays for handling a multiple of small light boxes such as berry or mushroom picking boxes and particularly to such trays which are optionally stackable or nestable depending upon their respective positions relative to each other.

It is an object of the invention to provide such a tray which may be injection molded of plastic so as to be relatively light in weight, low in cost and yet ruggedly sustain the shocks and strains to which such a tray is subjected in service.

The manner of accomplishing the foregoing objects as well as further objects and advantages will be made manifest in the following description taken in connection with the accompanying drawings, in which:

FIG. 1 is a fragmentary plan view of a preferred embodiment of the invention.

FIG. 2 is a vertical cross-sectional view of the invention taken on the line 2-2 of FIG. 1 and shows two trays of the invention in nested relation with each other.

FIG. 3 is a vertical longitudinal sectional view of the invention taken on the line 33 of FIG. 2.

FIG. 4 is a side elevational view of a pair of the trays of the invention in stacked relation with portions thereof broken away to illustrate structure otherwise hidden.

FIG. 5 is a vertical transverse sectional view of the invention taken on the line 55 of FIG. 4 and with portions of the structure broken away to illustrate elements thereof which would otherwise be hidden in this view.

FIG. 6 is a fragmentary horizontal detail sectional view taken on the line 66 of FIG. 3.

FIG. 7 is a perspective view of one of the cardboard mushroom picking boxes a multiple of which is adapted to be carried loaded in each of the trays of the present invention.

FIG. 8 is a perspective view of two of said trays in nested relation.

FIG. 9 is a perspective view of two of the trays of said invention in stacked relation.

Referring specifically to the drawings, it is the current practice to pick mushrooms into individual cardboard picking boxes 10, as shown in perspective in FIG. 7 and in dotted lines in the various views of the drawings. Wooden racks are ordinarily provided for carrying nine picking boxes at a time and these racks are used in shipping and storing the picking boxes up to the point of their ultimate sale to the retail customer. The racks are then returned to the packer for re-use.

One of the difficulties in using wooden trays for this purpose is that they are highly absorbent and tend to extract moisture from the product and thu dissipate a substtanial portion of the weight thereof before the product reaches the ultimate point of sale. This defect is largely eliminated in the present invention by substituting for such wooden racks an injection molded plastic tray 11 which is practically non-absorptive of moisture and which may be optionally placed in interfitting or nested relation with each other so as to occupy a minimum of space when being returned to the packer and on the other hand may be optionally assembled in stacked relation as when they are loaded with full picking boxes for the purpose of conveying the latter to market.

The trays 11 are identical and each tray includes end members 12 and 13. The end member 12 includes a horizontal transverse top plate 14 from the outer end por- 3,319,79 Patented May 16, 1967 tions of which corner legs 15 and 16 extend downwardly. These legs have downwardly tapering hollow bosses 17 and 17a extending outwardly therefrom, said bosses having deep tapering pockets 18 and 18a formed therein and opening upwardly through the upper surface of plate 14 and inwardly through corner legs 15 and 16. Extending downwardly from the bottom ends of bosses 17 and 17a are lugs 19 and 19a.

Spaced inwardly from corner legs 15 and 16 and also extending downwardly from plate 14 are interior legs 20 and 21. All of the legs 15, 16, 2t} and 21 are formed of thin material and are cast integral with top plate 14. At points disposed opposite legs 20 and 21 and adjacent their outer edges, the plate 14 is provided in its upper surface with shallow recesses 22 and 22a, within the areas of which said plate is provided with holes 23 and 23a, the purpose of which recesses and holes to be made clear hereinafter.

Tray end member 13 includes an upper horizontal plate 24 from opposite end portions of which corner legs 25 and 26 extend downwardly. Formed in the upper face of the plate 24 in locations opposite the legs 25 and 26, are shallow recesses 27 and 27a, within the areas of which, plate 24 is provided with holes 28 and 28a respectively.

Extending downwardly from plate 24 at locations disposed inwardly from the corner legs 25 and 26 are interior legs 29 and 30, these interior legs having wedge-shaped bosses 21 and 31a which protrude outwardly from said legs and have deep wedge-shaped pockets 32 and 32a respectively which open upwardly through plate 24 and inwardly through said legs. Extending downwardly from the lower ends respectively of bosses 31 and 31a are lugs 33 and 33a.

While the plates 14 and 24 of the end members 12 and 13 lie in the same horizontal plane, all of the legs of said end members extend inwardly therefrom at an angle of approximately 7 from vertical. The lower ends of legs 16 and '26 are connected together by a box supporting bar 34 having a reinforcing and box retaining flange 35 extending upwardly therefrom along its outer edge said flange being integral with said bar and with said corner legs 16 and 26. Legs 21 and 30 are connected at their lower ends by a box supporting bar 36 having a reinforcing and box dividing flange 37 extending upwardly therefrom midway between its opposite edges. A similar box supporting bar 38 and flange 39 connects the lower ends of legs 20 and 29. The lower ends of legs 15 and 25 are connected together by a box supporting bar 40 having an upstanding reinforcing and box retaining flange 41 along its outer edge. Each of these flanges is integral with the bar on which it is formed and with the legs connected by said bar.

In the views showing two trays 11 in nested relation, to wit: FIGS. 2, 3 and 8, the two trays have like ends together. This is the relationship in which the trays are stored and shipped. When the trays are separated and each is loaded with nine mushroom picking boxes 10, and it is desired to stack these trays thus loaded, alternate trays are placed in end-for-end reversed relation with the rest of the trays, whereupon they fit together as shown in FIGS. 4, 5 and 9. When thus stacked in alternately reversed relation, the lower ends of each of the bosses 17 and 17a of each tray extend into the shallow recesses 27a and 27 respectively of the tray therebeneath and the pins 19 and 19a of each upper tray extend respectively into the holes 28a and 28 of the tray therebeneath. In a like manner the lower ends of bosses 31 and 31a of each superimposed tray extend into the shallow recesses 22a and 22 respectively of the tray therebeneath. Lugs 33 and 33a of the upper tray of each pair then extend into holes 23a and 23 respectively of the lower tray. The interlocking means afiorded by these lugs and recesses and holes which are brought into engagement when the trays are in stacked relation, are provided to prevent horizontal displacement of any superimposed tray relative to the tray therebeneath.

The top plates 14 and 24 of each tray 11 are made of sufiiciently heavy material whereby these may be used as handles to lift a tray or several tnays stacked thereon with each of these trays filled with loaded picking boxes 10. Being injection molded from plastic, each tray 11 is relatively light in weight and adds little to the total weight of a stack of loaded trays compared to the weight of the product in the picking boxes. On the other hand trays 11 readily nest together as shown in FIGS. 2, 3 and 8 so as to occupy little space during shipment back to the packer in whose shed they originated.

The interior legs at each end of the tray 11 are preferably two in number but it is to be understood as comprehended by the invention that these may under certain circumstances be advantageously increased or decreased in number.

While only a single preferred embodiment of the invention is illustrated herein, it is to :be understood that this is for illustrative purposes only, and that various changes and modifications may be made in this particular embodiment without departing from the spirit of the invention or the scope of the appended claims.

The claims are:

1. In a picking box tray, the combination of: first and second end members, each of which includes a horizontal plate extending entirely across said tray at the top level thereof, a pair of thin walled corner legs united with inner edge portions of said plate at its opposite ends, and thin walled interior leg means united with said inner edge portion of said plate interiorly of said corner legs and symmetrically related therewith, said corner legs and leg means of both said plates inclining inwardly and downwardly from inner edges of the latter, the corner legs and leg means of said first end member being integrally connected at their lower ends respectively to the lower ends of the corner legs and leg means of said second end member by flat picking box supporting bars disposed horizontally and having vertical flanges extending upwardly from and lengthwise of said bars for retaining said boxes on said bars, said flanges being integral with said horizontal bars and said corner legs and interior leg means respectively to give said tray rigidity; deeply tapering channel bosses incorporated with said first corner legs and said second interior leg means and extending outwardly therefrom, said channel bosses opening upwardly and inwardly whereby two trays will interfit vertically a substantial distance in nesting relation, when like end members are placed together, but will be stackable with said bosses of the upper tray resting on the plates of the lower tray when unlike end members are placed together.

2. A combination as recited in claim 1 wherein interlocking means are provided on lower ends of said bosses and said plates which interengage when two of said trays are in stacked relation to prevent horizontal displacement of said trays from vertical alignment.

3. A combination as recited in claim 2 wherein said interlocking means includes lugs extending downwardly from lower ends of said bosses; recesses provided in said plates for receiving said bosses with holes provided within said recesses for receiving said lugs.

4. A combination as recited in any of claims 1 to 3 wherein each of said first and second interior leg means comprises a pair of interior legs and each of the legs of said second interior pair of legs is provided with a deeply tapering channel boss as recited in claim 1.
