SHIPPING AND DISPLAY CARTON Original Filed Sept. 16, 1957 4 Sheets-Sheet 4 INVENTOR. Char/es Todd ECKHOFF 8' SLICK 7 A MEMBER OF THE FIRM United States Patent 4 Claims. (Cl. 229-16) This invention relates in general to a tray and shipping container therefor and more particularly to a tray particularly suited for shipment and display of fresh fruit.

Most shipping containers used for fresh fruit and vegetables are suitable only for this purpose and, at the destination, the comestible must be transferred to a suitable display package. It is obviously desirable, however, to employ a container which obviates the necessity for rehandling the fruit or vegetable on arrival at the retail or wholesale distributing point.

It is therefore an object of this invention to provide a container into which fresh fruits and vegetables may be packed, but which is of such a structure that it may be disassembled into a plurality of containers which may be used for displaying the articles.

It is a further object of this invention to provide an open tray which may be prepared from a single sheet of paper board, corrugated cardboard or similar material and which may be superposed on one or more similar trays and the entire group packed in a larger container for shipment.

Still another object of this invention is to provide a sturdy cardboard or corrugated paper tray which, as part of a larger package, may readily be secured closed so that the contents thereof will not be spilled.

Further objects and advantages of this invention, if not specifically set out, will become apparent during the course of the detailed description which follows.

FIGURE 9 is a perspective view of a modified form of the tray, particularly characterized in that the end panels may be locked in place in a positive manner; and

FIGURE 10 is a plan view of the carton blank from which the tray of FIGURE 9 may be formed.

Broadly, the complete shipping package in its simplest form comprises two or more trays which are superposed within a preferably open ended, tubular container having top, bottom and side panels of at least suflicient size to enclose the longitudinal walls, .top and bottom of the stacked trays. The exterior container, of course, may be of any suitable size but is preferably large enough to allow for receipt of three of the trays. A three-tray package is about optimum in size and weight where in- 'ice dividual trays about 2-3 square feet in base area are used, for use with apples, pears and peaches. Where such use is contemplated, the trays, of course, are ideally of about the depth of the fruit for which the container is intended.

The exterior tubular carton may be constructed of cardboard or corrugated paper board as, with three trays stacked therein, it becomes adequately rigid. Obviously, however, other materials are suitable though not preferred.

Each individual tray is formed from a single folded blank and, in the simplest embodiment, has a rectangular base and a first sidewall panel articulated at right angles to the base along a first score line. The first sidewall panel is joined at either corner of its opposite (uppermost) edge with parallel strips which are spaced from and run parallel to the base of the carton. The parallel strips terminate at the opposite ends thereof in a second perpendicular downwardly depending panel, the dimensions of which are substantially equal to those of the first sidewall. The second panel is provided with means such as a glue tab or flap adapted to lie against the base. Other suitable fastening means may be employed for joining the panel securely to the base of the tray along an edge thereof. As just stated, except for the base and the parallel connecting strips at opposite ends of the two sidewalls, these wall panels are severed from the rest of the carton material. Articulated to the inward longitudinal edge of each parallel strip is another panel; and these panels, when folded downwardly to the base of the tray, form opposed end walls. Preferably these downwardly extending end portions have means for affixing them to the base of the tray. In the preferred embodiment of the invention, the base of the tray is provided with a plurality of slots for receiving tongues which depend from the downwardly extending end walls. In the most preferred embodiment of the invention, each downwardly extending end wall is scored in the middle thereof so that an additional panel may be formed at a right angle relative to the end wall which lies against the upper surface of the tray base and may be secured thereto.

Referring now to the drawings wherein like characters refer to like parts throughout, the exterior shipping carton, generally 10, preferably is formed of a rectangular blank folded to produce a tubular structure having opposed sidewalls 12 and 14 and opposed top and bottom walls 16 and 18. Tab 20 is joined along score line 22 to the base 18. As shown in FIGURE 4, the tab preferably is provided with suitable adhesive so that it readily may be bonded to panel 12 to form the completed tubular shipping carton.

Preferably, shipping carton 10 is provided with partial cut- outs 24 and 26 which may be folded either inwardly or outwardly thereby providing means for grasping the filled shipping container.

A blank from which one of the trays of this invention may be formed is shown in FIGURE 6. The blank comprises a rectangular baseportion 28 joined by means of score line 30 to panel 32. At either end of panel 32 and, more specifically, along score lines 34 and 36, parallel strips 38 and 40 are joined thereto. These preferably are no more than an inch or so in widththat is, they are only of sufiicient width to lend adequate rigidity to the carton. This width, of course, may vary depending upon the thickness and inherent rigidity of the corrugated material or cardboard used. Score lines 42 and 44, spaced from and parallel to the edge of the blank, join panels 46 and 48 to the parallel strips 38 and 40 respectively. Score lines 50 and 52 mark a junction of the parallel supporting strips 38 and 40 and panel 54, this panel being substantially co-extensive with panel 32. At the opposite end of this panel 54 is score line 56 adjacent which is found glue flap 58 which provides means for uniting opposite ends of the blank. The two end panels 46 and 48 are provided with tongues '60, 62, 164 and 566 of a suitable size for reception in and registration with slots 68, 70, 72 and 84 of base 28.

An alternative structure, and preferred embodiment of the invention, is that shown in FIGURES 7 and 8. As the structure is substantially identical to that shown in FIGURES 5 and 6, it will not be further described in detail except to point out that the modification involves retaining articulated panels, 76 and 78 rather than severing such panels entirely from panels 46 and 48. The 'only points of severance of each pair of panels are those outlined by the tongues. In this fashion, two extra reinforcing panels are provided whiich may be glued or otherwise secured to the base of the tray so as to provide additional rigidity. As a result, in this embodiment, the tongues 60, 62, 64 and 66 may be omitted. Thus, the score lines 82 and 84 may extend the full length of the panels.

However, the use of tongues 60, 62, 64 and 66 is to be recommended as it provides for rapid assembly from the carton blank and ensures proper positioning of end panels 46 and 48. Where the tongues and slots '68, 70, 72 and 74 are provided, there is no possibility of any variation in the angle included between parallel strips 38 or 40 and each respective end panel 46 or 48.

The tray is prepared by folding either the blank of FIGURE 6 or that of FIGURE 8 to form an enclosed rectangle. The leading edge of base 28 and glue tab 58 are held in'close proximity and thereafter panels 46 and 48 are folded in a downward fashion. Tongues 60, 62, 64 and 66 mate with slots 68, 70, 72 and 74 and tab 58 is secured to the base to complete the tray.

Where the preferred embodiment, that shown in FIG- URE 8, is assembled, panels 46 and 48 are folded downwardly at right angles to parallel strips 38 and 40 and panels 76 and 78 are folded in the opposite direction along score lines 80 and 82, so as to cause panels 76 and 78 to lie flat against base 28. Rigidity is assured by the fact that panels 76 and 78 are glued in place. Thus, the function of tongues 60, 62, 64 and 66 becomes largely that of serving as assembly guide'means.

As can be seen from the figures, the preferred embodiment of the invention involves the formation of side panels 32 and 54 in such afashion that indentations are provided at the top thereof. These provide means for readily grasping and removing any individual tray from the shipping carton v10. Alternatively, each side panel is provided with a cut-out arrangement similar to 24 and 26 of shipping carton so that it is possible to readily remove the desired tray, The structure shown in the drawings is to be preferred as against a tab arrangement similar to 24 or 26 since the notched structure shown provides ventilation for the fruit or vegetable within the tray, thus facilitating refrigeration. It further provides means for readily inspecting the contents of the tray.

In that form of the structure shown in FIGURE 9, a rectangular blank generally indicated at 90 is provided, this including a rectangular base portion 91 joined by a score line 92 to a panel 93. Parallel strips 97 and 103 are joined at either end of panel 93 along score lines 94 and 96. Strip 97 carries panels 98 and 99, these being movable along crease lines 104 and 106. Similarly, strip 103 carries panels 101 and 102 movable on crease lines 107 and 108.

Each of panels "99 and 101 is cut as at 114 to provide a tongue 116. A fold line 117 in panel 111 defines a glue flap 118, which enables a blank to be assembled into that form in which it appears in FIGURE 9. 7

Referring again to panel 9, flaps 121 and 122 are formed integrally of 'this'panel, each being of an overall length corresponding to the width of panels98 and 102. 'Also,

. each of panels 121 and 122 is cut out as at 123 to receive a tongue 116.

Upon assembly of the blank, the glue flap 118 is engaged with edge 124 of panel 91, the flaps 121 and 122 are moved upwardly to engage the underside of each of strips 97 and 103. At the same time, panels 101 and 102 and 98 and 99 are moved into position in which panels 98 and 102 are normal to panel 91, panels 99 and 101 rest flatly on panel 91, and flaps 121 and 122 are engaged with panels 98 and 102. The upstanding flaps 121 and 122 provide support for the strips 97 and 103. At the same time, the engagement of panels 99 and 101 with the bottom panel 91 serves to strengthen the container, while the engagement of tongues 114 and 116 with the cut-out portion 123 in each of the flaps provides locks against any end thrust upon the panels 98 and 102.

Obviously, many modifications and variations of the invention as hereinbefore set forth may be made without departing from the spirit and scope thereof, and therefore only such limitations should be imposed as'are indicated in the appended claims.

This application is a substitute for abandoned application Serial No. 684,095, filed September 16, 1957.
