Case ready stackable tray designs

Abstract

A shipping system for packing and transporting products, such as case ready food items, in which the products require a certain amount of separation between layers. The shipping system comprises a shipping unit, formed by at least one substantially open-topped tray, preferably two or more, that are stacked atop one another, with a cover placed atop the uppermost tray, and held together by banding or strapping. Preferably, the tray(s) and cover are fabricated from corrugated paperboard material.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention is directed to trays that are used for the packing and shipping of products for sale, in particular products that are prepared, packed and shipped in a condition in which they can be transferred directly from the shipping tray to a display case (“case ready” food products). The present invention is directed in particular, to packing and shipping methods and structures, for facilitated handling of plural ones of such trays, which can be stacked and maintained in a stacked configuration during shipping.

[0003] 2. Prior Art

[0004] Primary package trays, such as those constructed of molded plastic, molded foam, or paperboard, configured for the shipping of products, such as food products, in which the trays are configured to be stacked and maintained in a stacked configuration during shipping, are known. Such trays are used in the shipment of food products, such as case ready meat products, produce, etc.

[0005] Such products are in the prior art, shipped in corrugated package designs typically including an outer shipping container carton (e.g., “RSC”, “Bliss”, Die Cut Wrap or Lidded Tray configurations, as those are known as and referred to by those of skill in the art of food packing and shipping), and multiple pieces of inner packing, usually consisting of corrugated layer pads and “U”-pads (scored sheets, configured in a “U” shape and placed inside the shipper, one per shipper when used, with the legs in a downward direction so that it may serve as a shelf, dividing the amount of weight the layers of stacked trays must support). When the layers of product are added to the container, the separating layer pads and/or a shelf are used to displace the weight of the layers over a larger area, but this does not eliminate each of the lower layers from carrying some of the weight of the layers above. Because none of the inner packaging provides any real stacking support in a unitized (palletized) load format, this usually requires the outer box to be constructed of a heavy weight and costly corrugated substrate.

[0006] These and other desirable characteristics of the invention will become apparent in light of the present specification, including claims, and drawings.

SUMMARY OF THE INVENTION

[0007] The present invention is directed to a shipping system for the facilitated packing and transportation of items, wherein the items are of a type requiring separation between vertically stacked layers. The shipping system comprises at least one shipping unit.

[0072] FIGS. 13-21 are plan views of blanks for trays that may be used with the shipping unit system according to the invention. The blanks that are shown are all readily understood by those of ordinary skill in the art of corrugated shipping trays. By way of example, the manner of converting the blank shown in FIG. 13, into a tray, e.g., tray 21 of FIG. 2 is as follows.

[0073] Referring to FIG. 13, blank 90 includes bottom wall 91; end walls 92, 93 connected to bottom wall 91 by fold lines 94, 95; outer sidewalls 96, 97 connected to bottom wall 91 by fold lines 98, 99; inner sidewalls 100, 101 connected to outer sidewalls 96, 97 by fold line pairs 102, 103; first minor flaps 104, 105, 106, 107 connected to outer sidewalls 96, 97 by fold lines 108, 109, 110 and 111; gussets 112, 113, 114 and 115 connected to inner sidewalls 100, 101 by fold lines 116-119; and second minor flaps 120-123, connected to gussets 112-115 by fold lines 124-127. Blank 90 also includes apertures 128-133, and die cut stacking tabs 134-137.

[0074] To erect a tray 21 from blank 90, inner sidewalls 100, 101 are folded inward about fold lines pairs 102, 103, to overlie outer sidewalls 96, 97. Next, end walls 92, 93 are folded up about fold lines 94, 95 to be perpendicular to bottom wall 91. Outer sidewalls 96, 97 are then next folded up perpendicular to bottom wall 91. Depending upon the folding sequence, first minor flaps 104-107 may be positioned to the inside or the outside of end walls 92-93, and adhered thereto. Second minor flaps 120-123 may, depending upon the location of first minor flaps 104-107, be adhered to the insides of end walls 92-93 or alternatively, to the insides of first minor flaps 104-107. Gussets 112-115 will then be positioned perpendicular to bottom wall 91, and extend diagonally across the respective four corners of bottom wall 91. When stacked, the stacking tabs 134-137 will be received by the apertures 128 and 129, 132 and 133 of a like tray stacked above.

[0075] FIG. 14 illustrates a blank 140 that is generally similar to blank 90, except that no corner gusset panels are provided, and is erected in a substantially similar manner to that described for blank 90, except that the first and second minor flaps are connected to one another by double score lines.

[0076] FIG. 15 illustrates a blank 150 that is generally similar to blank 140, and is erected in substantially similar manner, in that the first and second minor flaps are connected to one another by single score lines. The stacking tabs are formed by cutting material from the inner sidewalls, and incorporating fold lines offset from the fold lines separating the inner and outer sidewalls, so that the stacking tabs are exposed, when the inner and outer sidewalls are juxtaposed to one another.

[0077] FIG. 16 illustrates a blank 160 that is generally similar in operation and manner of operation as blank 150 of FIG. 15. FIG. 17 illustrates a blank 170 that is also generally similar in form and operation as blank 150 of FIG. 15. FIG. 18 illustrates a blank 180 that is generally similar in form and operation to blank 140 of FIG. 14, except that single fold lines connect the first and second minor flaps. FIG. 19 illustrates a blank 190 that is generally similar in form and operation to blank 90 of FIG. 13, but includes a substantial number of ventilation apertures. Blank 200 of FIG. 20 also includes locking panels that emanate from the top edges of the end walls, which locking panels include sideways extending tabs that are received in slots formed between the inner sidewalls and the second minor flaps, so that blank 200 forms a self-locking tray that does not require adhesive. Blank 210 of FIG. 21 forms a tray having inclined sidewalls, without corner gussets.

[0078] FIGS. 22-23 illustrate blanks 220, 230, respectively, for die cut lids. These blanks are configured to accept stacking tabs, as well as having finger openings on the ends of the blank. FIGS. 24-25 illustrate blanks 240, 250, respectively, for shoe box type lids. These blanks are also configured to accept stacking tabs. The die cut lids and the shoe box type lids may alternatively not have apertures or notches for stacking tabs, if it is known that no stacking tabs will be used in the trays, for which the covers will be provided.

FIG. 34 illustrates a blank 430 for a tray, according to an alternative embodiment of the invention, which results in a tray having stacking shoulders 435, 440, 445 and 450, extending diagonally across the corners of the tray.

[0081] FIG. 35 illustrates a blank 460 for a tray, according to an alternative embodiment of the invention, which results in a tray having inclined side walls, due the inclined fold lines 465, 470, 475, 480, between the outer end panels and their respective minor flaps. Blank 460 also produces a tray having corner gussets formed by panels 485, 490, 495 and 500.

[0082] FIG. 36 illustrates a blank 510 for a tray, according to an alternative embodiment of the invention, which results in a tray having inclined side walls, created by the acute angles between the outer side wall minor flap fold lines 515, 520, 525, 530, and the bottom edges 535, 540, 545, 550 of their respective outer side wall minor flaps. Blank 510 also produces a tray having corner gussets formed by panels 555, 560, 565 and 570.

[0083] FIG. 37 illustrates a blank 580 for a tray, according to an alternative embodiment of the invention, which results in a tray having inclined side walls, formed by created by the acute angles between the outer side wall minor flap fold lines 585, 590, 595 and 600 and the bottom edges 605, 610, 615, 620 of their respective outer side wall minor flaps. Blank 580 also produces a tray having inclined end walls, created by the acute angles between the outer side wall minor flap fold lines 585, 590, 595 and 600 and the fold lines between the bottom wall 625 and the outer side walls 630, 635. Blank 580 also produces a tray having corner gussets formed by panels 640, 645, 650, 655.

[0084] FIG. 38 illustrates a blank 660 for a tray, according to an alternative embodiment of the invention, which results in a tray having a stacking shelf created by increasing the width of the bridge between the two vertical end or “depth” panels. In addition, the angled minor flaps 665, 670, 675, 680 coming off the ends of the inner end or “depth” panels, causes the interior volume of the tray to have a truncated pyramidal shape, in that the inside distance at the bases of the end or “depth” panels is greater than the inside distance between the tops of the end or “depth” panels.

[0085] FIG. 39 illustrates a blank 690 for a die cut lid, having downwardly foldable end flaps, according to another embodiment of the invention, suitable for use with trays with or without stacking tabs.

[0086] FIG. 40 illustrates a blank 700 for a shoe box type lid, according to another embodiment of the invention, suitable for use with trays with or without stacking tabs, in which the lid has its own stacking tabs 705, 710, 715, 720.

[0087] FIG. 41 illustrates a blank 730 for a shoe box type lid, according to another embodiment of the invention, suitable for use with trays with or without stacking tabs.

[0088] In a preferred embodiment of the invention, a complete shipping system is created, when each of the blanks produces a tray having the same “footprint” and locations for the stacking tabs and receiving apertures (if used), with all of the covers (whether pads or shoe box type) having suitably located slots, to receive the stacking tabs from any of the trays, so that a maximum degree of flexibility is attain to the extent that non-identical trays can still be stacked atop one another, covered by a suitable pad or shoe box lid, and banded or strapped as required.

[0089] The shipping unit system of the present invention is intended to provide substantial flexibility, in providing for the packing and transportation of items that require a certain degree of separation. This system uses a number of single layer trays to replace the present package designs. Each layer tray carries a single layer of product or primary containers and is capable of providing the necessary stacking strength for each layer of the stack as well as through the unit and the palletized load of collected packages. This provides substantial flexibility as multiple layers of trays, each carrying layers of products can be stacked on top of each other. To enclose the pack, a single cover (die cut pad, tray or scored sheet) is needed to enclose the products in the top tray; as the bottom of each of the lower trays provide the cover for the tray below. To establish specific case pack quantities, stacked layer trays are combined together, with the use of plastic strapping, tape, or a wider band of a variety of materials, that can be either printed or plain, any color, or in the case of plastic film, may be clear, translucent or opaque.

[0090] This system has economic advantages through minimizing the number of different, usually exclusive, packaging components found in prior art systems, as well as improving the stacking contribution of the individual components. This system can also permit the reduction of the overall material usage in the package. Furthermore, whereas prior art containers have been limited to manual packaging means, the shipping system of the present invention provides the opportunity to employ automated methods, reducing the labor requirement involved in the packaging process.

[0091] The foregoing description and drawings merely explain and illustrate the invention, and the invention is not limited except insofar as the appended claims are so limited, as those skilled in the art who have the disclosure before them will be able to make modifications and variations therein without departing from the scope of the invention.
