United States Patent 50 CARRIER TRAY FOR CONTAINERS Mildred R'Longan, Baldwin Park, Califi, assignor to Renfro-Franklin Company, Baldwin Park, Calif., a corporation of California.

Application October 11, 1957, Serial No. 689,647 8 Claims. (Cl. 220-117) This invention relates to a wire tray for carrying containers, such traybeing particularly adapted ,for use in carrying cardboard cartons and glass bottles ofmilk.

Trays of the class described generally comprise a bottom wire frame having a plurality of cross wires which support the bottom'of the containers, an upper frame having a plurality of cross wires which define the container receiving areas and which also secure the two layerstogether, and a wire handle, which is customarily secured to both frames.

In the past, one weakness of such trays has been the means of attaching the handle to the tray and particularly to the upper frame thereof. Such attachment customarily comprises spot welding the handle to the upper frame at the point where they cross. Since trays of this type are customarily subjected to considerable use and abuse, the handle will sometimes work loose. This can cause the user to drop oneor more glass bottles and possibly injure himselfl causing legal difliculties for the dairy or other company which furnishes the carrier.

It is accordingly an object of my invention to overcome this weakness by providing a novel structure in which the handle cannot become substantially displaced with respect to the upper name, even a spot weld attachment may come loose. ,In essence, my invention contemplates achieving this result by providing a safety ring or loop which encircles thefhandle adjacent its point of attachment to the upper frame. The loop is spot welded to the upper'frarne at two places'dir ecfly adjacent to the point of attachment of the handle and upper frame. With my construction, "a considerable number of 7 different spot welded attachments would have to work loose before the handle could move substantially with respect to the upper frame] It is therefore an object of my invention to provide an improved construction for carrier trays in which the handle is more securely-attached to the tray.

It is another object of my invention to provide a carrier tray which is ,capable of being stacked upon itself. It is more particularly an objectof myinvention to provide such a stacking tray without in, any wayweakening or deforming any of the structurural parts of the tray. In the past, some stacking trays have been made stackable by cutting or bending the wires of which the tray. is formed or, by failing toprovidecontinuous wires. In essence, my invention contemplates a tray which can be stacked because the handle extends through an open area adjacent the center of the tray, such open area being formed without any wires being cut, shortened or deformed in any y It .is a further object of my invention to provide a car- 'rier tray having a handle structure .with a protective ring, with the handle structure being doubled for added strengthand safety, both handles being enclosed within the protective ring. v

It is accordingly among the objects of my' invention to provide a carrier tray having all of the advantages and benefits of the structures set forth above. It is a 2,896,815 Patented Jul 28, 1959 "ice further object of my invention to provide such trays which are simple and economical to manufacture and which are strong and safe to use.

My invention also comprises such other objects, advan: tages and capabilities as will later more fully appear and which are inherently possessed by my invention.

While I have shown in the accompanying drawings preferred embodiments of my invention, it' should be understood that the same are susceptible of modification and change without departing from the spirit of my invention.

, Referring to the drawings, Fig. 1 is a perspective view of a perspective view of a preferred embodiment of my invention.

Fig. 2 is a side view of a pair of trays of the type shown in Fig. 1, stacked one on top of the other.

Fig. 3 is a perspective view of the handle and center portions of an alternative embodiment of my invention.

A preferred embodiment which has been selected to illustrate my invention comprises a substantially rectangular bottom frame 10, which is preferably formed of wire. A plurality of straight support, wires 11 extend longitudinally across the bottom frame 10. The support wires 11 have loops 12 formed at their opposite ends, such loops 12 extending around the ends of the bottom frame 10 and being spot welded thereto.

, An identically formed upper frame 13 is disposed above the bottom frame 10. A pair of spacer wires 14 have their midportions extending transversely across the upper frame 13, with their end portions 15 being'bent at a right angle to provide side members which extend vertically downwardly from the upper frame 13 to the bottom frame 10. The ends of the spacer wires 14 have loops 16 formed at their opposite ends, such loops -16 extending around the sides of the bottom frame 10 and being spot welded thereto. The portions of the spacer wires 14 which cross the sides of the upper frame 13 are spot welded thereto.

A pair of parallel center wires 17 extend longitudinally from one end of the upper frame13 to the other. The ends of the center wires 17 are joined in a pair of safety loops or rings 18', which protrude slightly beyond the ends .of the upper frame 13. The portions of the center wires 17 which cross the spacer wires 14 are spot welded thereto. The end portions of the center wires 17 adjacent the rings 18 are spot welded to the ends of the upper frame, 13. a a a A handle 19 has a pair of loops 29 at its opposite ends which extend around the midportions of the ends of the bottom frame 10 and which are spot welded thereto. Extending vertically upwardly from the loops 20 are a pair of side portions 21, which extend to the upper frame 13, passing through the rings 18 and being'spot welded to the midportions of the ends of the upper frame 13. The handle 19 continues with a pair of angular portions 22 which extend inwardly and slightly upwardly to a point slightly toward the center of the tray from the spacer wires 14. From these points, the handle 19 extends vertically upwardly to provide a pair of parallel upright portions 23, which are joined at their upper ends by a horizontal bail 24. The width of the bail 24 is slightly less than the distance between the spacer wires 14.

While the component parts forming my tray are preferably formed. of metal wire and are preferably integral in the manner shown and described, it should be understood that other suitable materials may be used and that the structural details may be varied or several pieces joined together or combined, to serve the purposes de scribed. i

It will be noted that with this structure, the handle 19 is securely held against displacement from the upper frame. If the spot weld attachment securing the handle 19 to the upper frame 13 should come loose, the ring 18 would prevent any substantial movement of the handle 19. If one or both of the spot welds between the center wires 17 and the end of the upper frame 13 came loose, the center wires would still be held by the welded attachmerits Where they cross-the spacer wires 14Qas well as the attachments at the other end of the frame. It is thus substantially impossible for the handle 19 to come loose without almosttotal destruction of the tray.

Another-advantage of my structure is that the trays can be stacked one on top of another. This is possible because the distance between the upright portions 23 of the handle 19 is less than the distance between the spacer wires 14. Thus, when one tray is placed on top of another, the upper portion of the handle passes through the open space between the support wires 11 of the bottom frame and then through the open portion of the upper frame 13 defined by the spacer wires 14 and the center wires 17. 1

Another embodiment of my invention provides'added strength and safety by including a second handle 19a, which is formed identically with the above described handle 19.' The handles 19 and 19a are both secured to the tray in the same manner and are also spot welded to each other, preferably adjacent the upper end of the upright portions 23 and 23a. A name plate 30 extends between the upright portions 23 or 23a of either of the handles and is spot welded thereto. In use, decalcomania or other label may be applied to the name plate 30 to identify the dairy or other company which owns the tray. The double handle structure provides added strength for carrying heavy loads and makes the tray easier to grip and carry. It should be noted thatboth of thehandles 19 and 19a extend through the safety rings 18 and are held against displacement in the manner described above.
