TRAY AND METHOD OF MAKING SAlVIE George A. Lyon, Jr., 13881 W. Chicago Blvd., Detroit 28, Mich.

Filed Feb. 3, 1958, Ser. No. 712,984

6 Claims. (Cl. 220-74) This invention relates generally to a tray construction and method of making same which tray may be used as a meat platter or for any other suitable purpose.

The tray is adapted to be manufactured from sheet metal stock from which tray blanks are cut and formed As is illustrated, the tray is dished and the margin of the tray has been particularly constructed according to certain features of the present invention. To this end, the margin has a peripheral edge comprised of a double thickness of metal which operates to greatly reinforce the tray structure and to increase its life span. The double thickness of metal at the margin is brought about by reverse bending the material at the periphery of the dished blank with the bent or deflected portion welded to an inner portion of the tray and thereafter abraded or buffed about the weld area to impart to the tray the appearance that the tray was cast or molded, and the like, as opposed to being made from relatively inexpensive sheet stock. In addition to the foregoing, by utilizing a U-shaped double thickness of metal at the tray margin, the peripheral edge of the tray may be ground or otherwise finished in a manner so as not to expose the parting line between the abutted legs of the U-shaped portion of the tray margin. By this expedient, the true construction of the tray may be effectively concealed while the tray margin may be considerably reinforced. Still another advantage of the present construction resides in the fact the extra thickness of metal is here disclosed as being utilized on the top side of the margin so that a greater volume of meat juices and the like may be contained over an enlarged area should they fall upon the tray margin inward of the double thickness of metal.

According to the objects of the present invention there is provided a new and improved serving tray construction and method of manufacturing the same.

According to another object of the present invention, a new and improved serving tray construction has been provided which may be manufactured from sheet stock and yet has the appearance of being cast or manufactured in some other more expensive manner.

A further object of the invention is to provide a new and improved food platter construction and method of manufacturing the same which lends itself to economical manufacture on a large production basis.

Yet another object of the present invention is to provide a new and improved method of manufacturing trays from sheet stock whereby a very low unit cost of manufacture may be vmaintained.

Other objects and features of the present invention will more fully become apparent in view of the following detailed description taken in conjunction with the accompanying drawings illustrating therein a single embodiment and in which:

Figure 1 is a plan view or a top elevation of a serving tray;

Figure 2 is an enlarged cross-sectional view taken substantially on the line IIII of Figure 1 looking in the direction indicated by the arrows;

Figure 3 is an enlarged fragmentary cross-sectional view illustrating the tray in a preliminary stage of formation;

Figure 4 is an enlarged fragmentary cross-sectional view in full and dotted lines illustrating a more subsequent stage of manufacture;

Figure 5 is an enlarged fragmentary bottom plan view of the outer margin of the partially completed tray or platter;

Figure 6 is an enlarged fragmentary cross-sectional view similar to Figure 4 only wherein the peripheral edge of the tray is machined or abraded and where the weld seam has been abraded; and

Figure 7 is an enlarged fragmentary bottom plan view highlighting the underside of the tray margin following the abrading operation whereby the weld line is concealed.

As shown on the drawings:

The reference numeral 10 in Figure 1 indicates generally my platter or tray construction. The platter 10 may be most economically manufactured from sheet stock such as stainless steel and the like. Initially, a dished blank 11 is cut from the strip stock and is formed in a manner hereinafter described in detail.

The dished tray blank 11 includes a central dished area or portion 12 which may be suitably embossed if desired to provide recesses for meat drippings and the like. At the outer periphery of the bowl or dished portion 12 is provided an annular marginal flange structure 13. The flange structure 13 includes an inner marginal portion 14 and an outer prescribed flange structure 15. The peripheral flange structure 15 has a generally U-shaped cross-section when formed to final shape as is apparent from Figures 2, 4, and 5 and wherein the legs are identified at 15a, 15b, and the junction of the legs at 150.

During the formation of the tray blank 11 the leg 15a is partially oflset out of the plane of the marginal portion 14 and is joined therewith by an inclined annular leg 16. Generally at the same time the leg 15b is turned generally at right angles with respect to the leg 15a; The peripheral flange area is particularly divided in a manner whereby the length of the leg 15b is predetermined in a,

manner so that its outer edge 15d will be abuttingly engaged against the inclined annular leg 16 for purposes which will hereafter become apparent. Following the preliminary formation of the marginal area of the tray blank, the leg 15b is turned in a manner whereby it is disposed in a plane common to the inner marginal portion 14 and is abutted against the under surface of the leg portion 15a along parting line 15d so that the edge 15e is abutted against the inclined leg 16 at shoulder 16a along annular junction line 17.

In order to maintain the leg 15b in abutment against the leg 15a and the edge He in abutment with the shoulder 16a, the leg 15b is preferably welded in assembly with the surface area it is abutted against as is shown in Figure 6. The welding process may be eifectuated in any suitable manner such as by an electric arc welding type process and the like.

Either before or after the welding operation, the rounded outer marginal edge disposed at the bottom of the U as indicated at 150, may be suitably ground or abraded flat as indicated at 15 This grinding or abrading operation is controlled in a manner whereby a portion of the bottom of the U is allowed to remain as a link between the legs 15a and 15b and whereby the portion is also allowed to remain to provide means for concealing the parting line 15d.

As is evident in Figure 5, the annular junction line 17 is apparent from the bottom side of the tray and which junction line 17 is subsequently obscured by the weld between the edge 15a and the shoulder 16a (Figure 6). The final operation in the manufacture of my tray involves abrading or bufling the area of the weld in order to impart a smooth unblemished appearance to the underneath surface of the margin 13 in a manner as is shown in Figures 6 and 7. In view of the foregoing it will now be appreciated how a reinforced sheet metal tray may be provided and how the double flange tray margin construction may be eflectively concealed to greatly enhance the overall appearance of the sheet metal tray.

It will be understood that modifications and variations may be effected without departing from the scope of the novel concepts of the present invention.
