Davis, Fullerton, Calif., assignor to Container Corporation of America, Chicago, 111., a corporation of Delaware Filed Apr. 20, 1964, Ser. No. 361,616 4 Claims. (Cl. 220-97) This invention relates to open top trays adapted to be stacked on one another, and more particularly, to improvide handle means that maintain stacked trays in proper vertical alignment and that increase the load carrying capacity of the tray because of the improved cooperation with the end wall construction of the tray.

Open top trays formed of paperboard are commonly used in the packaging and transporting of berries, fruits, vegetables and other produce commodities. These trays are filled in the fields at harvest time, both the empty and full trays being stacked to considerable heights so as to save space and be readily usable. To minimize tipping of the stacked trays, particularly when they are loaded, it is desirable to maintain all of the trays in proper vertical alignment. It is also desirable that the handles of the tray be securely fastened to the tray so as to permit continued use of the trays without the handles tearing therefrom.

Accordingly, a primary object of this invention is to provide, in an open top paperboard tray, an improved handle-end wall arrangement particularly adapted to facilitate propertly aligned stacking of like trays and to fasten securely the handle to the tray to increase durability of the tray.

A more specific object of the invention is to provide, in a multi-ply end wall tray, a wire handle, the handle having a lower portion adapted to engage the underside of the tray, an upper portion extending above the tray for receipt within a like end wall of an adjacent tray, and a medial portion adapted to engage a portion of the tray end wall to maintain the handle in proper position relative to the end wall.

These and other objects of the invention will be more fully understood and appreciated after reviewing the following specification including as a part thereof the accompanying drawing, wherein:

FIGURE 1 is a top plan view of a tray arrangement embodying features of the invention;

FIGURE 2 is an enlarged partial vertical sectional view of two stacked trays taken on line 22 of FIG- URE 1;

FIGURE 3 is a fragmentary end view of one tray structure illustrated in FIGURE 2, with portions of the structure broken away; and

FIGURE 4 is a perspective view of the wire handle element.

Referring now specifically to the drawing, a typical tray for which this invention forms an improvement is shown. The tray 10 may be formed of corrugated paperboard or the like and comprises a bottom wall 12, and oppose-d pairs of side walls 14 and end walls 16 upstanding from bottom wall 12. Side walls 14 and end walls 16 are interconnected to one another at the corners of the tray 10, and a divider wall 18 commonly extends across the tray between the spaced side walls 14 in general parallel relationship to the end walls 16. As is well known in the art, trays of this type are stacked on one another, and for this purpose enlarged seats 20 are located at the corner junctions of the side walls and the end and divider walls to provide load bearing support for the stacked trays even it they shift slightly transversely of the stack.

For the most part, the specific tray construction is immaterial, so that only the areas of particular interest and importance to the subject invention will be disclosed in detail.

FIGURES 2 and 3, disclose an end wall construction suitable for use with the subject invention. The end wall 16 is multi-ply having an inner panel 22 and an outer panel 24 interconnected at their upper ends by a top panel 26. In the disclosed construction, the bottom wall 12 has a hinged portion 28 that extends between

panels

22 and 24, the hinged portion being bonded by appropriate adhesive to outer panel 24 to form therewith in eflect, a composite outer end wall panel spaced from inner panel 22.

A deflectable tab 36 is hinged at hinge line 37 to bottom wall 12, and provides thereby an opening 38 through the bottom wall adjacent the end wall. A retaining tab 40 is cut from top panel 26 to provide a top opening 42, the tab 40 being integral with and upstanding from inner panel 22. The inner and outer panels are horizontally spaced from one another between the

openings

38 and 42, so that end wall 16 has intermediate its ends a medial channel through which an elongated type wire handle element 44 (FIGURE 4) can be extended.

The wire handle element 44 is formed from a sufficiently strong gauge wire butt welded together, such as at 46, to be endless around its entire length. In its finished form, wire handle 44 has two spaced substantially parallel, elongate-d, side members 48 interconnected at their upper ends by cross member 50 and at their lower ends by cross member 52. Lower cross member 52 further has a pair of relatively short side elements 53 connected at corresponding ends to the side members and connected at the opposite ends by cross element 54.

In its inserted position, the wire handle element fits between the inner and outer panels of the end wall structure until the

lower elements

53 and 54 engage the underside of the tray. Toward the furtherance of maintaining the underside of the bottom wall 16 flat or uniform while still providing a strong handle tray connection, inner panel 22 has its lower edge 65 generally adjacent and in line with deflectable flap 36 spaced from the bottom wall slightly, so that the flap can rotate about hinge line 37 until it abuts the inner panel 22 to form thereafter a solid support with the end wall. The cross element 54 engages the flap slightly outboardly of hinge line 3-7 to cause this flap deflection. The lower member 52 of the handle fits within opening 38 provided after deflection of the flap to provide a substantially flat or uniform underside for the tray 10.

The side members of handle 44 further have between the connected

spaced locations

50 and 52 medial bends 55 extending transversely to the plane defined by the side members. Each medial transverse bend 55 has a lower surface 56 that cooperates with upper edge 58 of inner panel 22 when the handle is fully inserted into the end wall. Further, the sides of the transverse bends 55 engage the opposite sides of the medial tab 40 on inner panel 22. This engagement by the medial bent portions 55 of the handle prevents transverse or vertical displacement of the side members 48 of the handle relative to the end wall on each other. Thus, when the trays are stacked on one another, the handle elements in the lower tray are received within the open end wall structure of the upper stacked tray to fix the trays in proper vertical alignment. The upper portion of each handle 44 at end 50 extends through the opening in its top panel to provide handle means for the tray. In the stack, upper surface 60 of the transverse bends 55 and tab 40 nest within the opening 38 in the bottom wall provided by deflected flap.

It is thus seen that the disclosed handle end wall arrangement securely fastens an otherwise detachable handle to the tray while providing load bearing support on both the bottom and end walls. Furthermore, the subject handle is transversely and vertically locked to the end wall to help maintain proper vertical alignment of the stacked trays, since two cooperating trays in a stack by necessity have to be stacked properly.

While only a single embodiment of the subject invention has been disclosed, it will be obvious to those skilled in the art that modifications can be made therefrom without departing from the inventive concept of the disclosure. Accordingly, it is desired that the invention be limited only by the scope of the claims hereinafter following.
