Aqb $5 DISPLAY TRAY WITH DEPENDING SKIRT The present invention relates to an improved open top tray of the type finding utility as a container for articles shipped to supermarkets and the like. More particularly, the invention is directed to a collapsible tray fabricated from a single paperboard blank, the tray being shipped in a flat or collapsed form and being readily erectable at the point of use without any need for tools or fastening means of any type.

Storage trays for use in applications of the type in which thepresent invention finds utility have taken many physical forms and have been manufactured using various materials and techniques. These prior art trays, while serving a useful purpose, have not been satisfactory in all respects. In particular, the shallowness of the trays has resulted in a front wall or panel which is relatively short in vertical height and which does not provide an adequate display or advertising area in which properly to describe the product and to promote its sale. Moreover, the trays of the prior art have included no simple means by which undesirable shifting or rearward displacement of the tray on the shelf is prevented. It is the aim of the present invention to provide an improved collapsible tray of unitary construction which obviates the above and other shortcomings of prior art devices.

It is a principal object of the invention to provide a relatively shallow, collapsible tray of unitary construction which, the overall depth of the tray notwithstanding, hasa front or face panel of substantial vertical expanse and in which the front panel still permits a viewing of the articles in the tray.

It is a related object of the invention to provide a collapsible, open top tray which includes a front panel or front wall structure which obviates the trays sliding rearwardly on its supporting shelf.

Another object of the invention is to provide a display tray which, while sturdy and stable in use, is readily collapsible for shipment or storage.

A related object of the invention is to provide a display with an integrally formed front wall placard, the tray being quickly and readily transformed from a substantially flat configuration to a completely selfsupporting' structure, without any need for tools, complex manipulative procedures, or auxiliary aids.

Other and further objects, features and advantages of the invention will become apparent from a reading of the following specification taken in conjunction with the drawing in which: I

FIG. 1 is a perspective view of the display tray of the invention in place on a supporting shelf;

FIG. 2 is a front elevational view of the tray;

,FIG. 3 is a side elevational view;

FIG. 4 is a top plan view;

FIG. 5 is a longitudinal cross sectional view of the tray taken substantially on the lines 5-5 of FIG. 4;

FIG. 6 is a transverse cross sectional view of the tray taken substantially on the lines 66 of FIG. 4;

FIG. 7 is a fragmentary, enlarged cross sectional view taken substantially on the lines 77 of FIG. 4; and

FIG. 8 is a plan view of the blank from which the tray of the invention is made, lines or scores upon which the blank is designed to be folded being shown in broken lines.

The aims and objects of the invention are accomplished by providing, in a display tray, a skirt constituting a downwardly directed extension of the front panel of the tray, the skirt as well as the front panel being an integral extension of the floor panel of the tray.

Referring more particularly to the drawing, there is shown for the purpose of illustrative disclosure, a preferred embodiment of the tray of the invention. In the specific form depicted, the tray 20 illustrated comprises, as best shown in FIGS. 1-3, a floor panel 24, a pair of

opposed side panels

26 and 28 joined to the floor panel along fold'lines 32 and 34 (FIG. 8), a rear panel 36 connected to the floor panel 24 along a fold line 38, and a front panel 42. The front panel 42 constitutes an integral extension of the floor panel 24 and includes a downwardly extending skirt 46 formed by a flange 50 connected to the floor panel 24 along a fold line 52. At its lower extremity, the flange 50 is integrally joined along a foldline 54 to a coextensive upwardly directed web 56 constituting the lower portion of front panel 42 of the tray. That is, the flange 50 and that portion 56 of the front panel which overlies the flange 50 extend below the shelf 60 on which the tray is supported so that the forward edge 64 of the shelf 60 seats within the corner formed by the floor panel 24 and the skirt 46 to prevent rearward displacement of the tray on the shelf.

In the specific form of the tray illustrated, the rear panel 36 includes, at each end, a pair of opposed wings or hinge tabs and 72 integrally joined to the rear panel 36 along

fold lines

76 and 78, the tabs extending inwardly into the tray and perpendicularly to the rear panel 36 to overlie, contiguously, the corresponding end portions of the

side walls

26 and 28.

The rear end portions of the

side walls

26 and 28 are formed with angularly directed

corner fold lines

80 and 82 extending from a lower corner juncture of each of the

side panels

26 and 28 with the floor panel 24 and the rear panel 36, the

fold lines

80 and 82 being angled upwardly and inwardly from each corner juncture to the top edge of each

side panel

26 and 28. Adhesive means 84 secure the

hinge tabs

70 and 72 to the adjacent rear end portions of the

side panels

26 and 28, the attachment of the cooperating elements being restricted to the zones 80a and 82a rearward of the

angled fold lines

80 and 82, whereby inward folding of the

side panels

26 and 28 along the

fold lines

32 and 34 and the

angled fold lines

80 and 82 operates to effect inward pivotal collapse of the

side panels

26 and 28 upon the floor panel 24 and inward pivotal collapse of the

wing tabs

70 and 72 along the

vertical fold line

76 and 78 while obviating any folding of the wing tabs themselves. An important advantage of the structure described is that the

wing tabs

70 and 72 thereby constitute pivoting mechanical stabilizers operable to support the

side panels

26 and 28 of the erected tray 20in an upright position when the

hinged tabs

70 and 72 are in substantially full abutment against their

respective side panels

26 and 28 and the tray is ready for use.

Connected to the

side panels

26 and 28 at forward extremities thereof defining

fold lines

86 and 88 are a second pair of wings or hinge

tabs

92 and 94 which extend contiguously along and are secured to the rear face of the front panel 42. In the preferred form of the invention illustrated, the

wing tabs

92 and 94 are generally L-shaped to add additional strength and stability to the final structure. At their forward ends the

side walls

26 and 28 are formed with upwardly and rearwardly directed

fold lines

96 and 98 extending from the corner juncture formed by the

side walls

26 and 28, the

wing tabs

92 and 94, and the floor panel 24, the

fold lines

96 and 98 in cooperation with the forward

edge fold line

100 and 52 facilitating forward pivotal collapse of the front panel 42 to provide a flattened tray structure.

While the disclosure presented is that of a preferred embodiment of the skirted tray, and while specific details of such features as fastening techniques and tray shapes have been described with respect to a preferred embodiment, it is apparent that numerous modifications and variations in structural details, materials used, and in the final overall appearance may be made without departing from the underlying principles of the invention.

With the teaching of the present invention before them, those skilled in the art will be able to deduce many substantially equivalent variations none of which constitutes a material departure from the present invention. It is, therefore, desired by the following claims to include within the scope of the invention all such variations and modifications by which substantially the results of this invention may be obtained through the use of substantially the same or equivalent means.
