The present application is directed to a display tray assembly. More specifically, the present application is directed to a freezer tray assembly for use in the display of products in a retail environment.
Current shelving systems, specifically freezer shelving systems, are designed to accommodate one or only a few varying product offering and/or shelf sizes. Universal shelving systems having a base and adjustable side walls for use with product packaging of any size and dimension, are not currently available. Such current systems also do not offer such functionality with a pusher having a forward bias for keeping product faced to the front of the shelf.
The system of the present application includes a display tray assembly having base and center tray sections that are configured to form a gap that receives a side tray section on either side. The side tray sections are configured such that they may move laterally with respect to the base and center tray section in order to adjust the width of the entire display tray assembly to accommodate any size product in a retail environment. In lieu of side tray sections, the display tray assembly may include union tray sections that may engage two separate base and center tray section assemblies in order to create a continuous display tray assembly with adjustable widths.

In the illustrated embodiment of
In one exemplary embodiment, the ribs 22 are spaced apart by a distance (as measured between the peak 25 of two adjacent ribs 22) of between about 2% and about 6% of the width of the center tray section 20. In one embodiment, the ribs 22 are spaced apart by a distance of about 4% of the width of the center tray section 20. In still further non-limiting embodiments, the ribs 22 are spaced apart by a distance of between about 10% and 20% of the width of the center tray section 20. It is understood, however, that the ratio of the width between the ribs 22 and the width of the center tray section 20 may vary according to the parameters of the containers or packages, including weight, bottom footprint, configuration of the portion of the container or package that rests on the ribs, etc. The ribs 22 are spaced so as to minimize the number of contact points with the container, which minimizes friction and facilitates sliding of containers along the plurality of ribs 22. In addition, the spacing between the ribs 22 makes it easy to clean the glide strip. Specifically, the concave configuration of the valleys 27 and the convex configuration of the ribs 22 provide a smooth cross-section, without sharp corners or crevices, within which contaminants can be trapped. This feature provides for easy cleaning of embodiments of the freezer tray assembly 10.
In the illustrated embodiment, the height of the ribs 22 is between about 0.01 inch and about 0.1 inch, and more preferably, about 0.06 inch although the height of the ribs may vary for different containers or packages. The distance between the ribs 22 is between about 0.2 inch and about 0.5 inch, and more preferably, about 0.3 inch although again the spacing of ribs 22 may vary for different containers or packages. In an embodiment, the convex top of each rib 22 is preferably rounded, having a radius of curvature between about 0.05 inch and about 0.125 inch, which in a further embodiment is about 0.06 inch. The concave rounded side walls of the ribs 22 exemplarily have a radius of curvature between 0.05 inch and about 0.2 inch, and in one non-limiting embodiment, about 0.125 inch. As further depicted in
As disclosed above, and in further detail herein, the plurality of ribs 22 minimizes the surface area that is in contact with a bottom surface of a container supported by the plurality of ribs 22. In particular, the radiused peak of each rib 22 provides point-type contact that significantly reduces contact surface area, while not digging into or otherwise damaging the material of the container, and without the package or container digging into, or otherwise damaging the material of the ribs 22 themselves, as could occur with ribs that have a more pointed construction. The radiused peak of each rib 22 functions to deflect or route pressure or stress on the rib 22 from the package or container radially downwardly to the valleys 27, much in the same manner as is accomplished by a Roman arch design. This cross-sectional configuration of the ribs 22 functions to dissipate the force and pressure from the container or package into the valleys 27, and decreases pressure and rib deformation or creep from the weight of the container or package, which greatly enhances the ability of the containers or packages to move along the ribs when a force is applied. Creep is undesirable because it presents increased friction between a container and its supporting surface and thereby can inhibit the sliding movement of the containers along a shelf or other support structure. By eliminating creep, as mentioned above, the center tray section 20 as disclosed reduces the force required to translate containers or packages along the center tray section 20.
At least an upper surface of the center tray section 20 as disclosed herein may be formed of a low friction material, which further facilitates the forward sliding movement of containers along the plurality of ribs 22. Exemplarily, the upper surface of the glide strip 10 may be formed of a Teflon material such as a DuPont Teflon® grade 7B granular compression molding resin or an ABS plastic material incorporating a low friction agent such as Siloxane, although it is understood that any other satisfactory low friction material may be employed. The center tray section 20 may be over-molded, coated, sprayed, or simply made of low friction material. Alternatively, the center tray section 20 may be made of a material that includes a low friction additive such, but not limited to, Teflon.
This disclosed embodiment of the center tray section 20 is, in embodiments, dimensioned particularly for the types of containers or packages with which the freezer tray assembly 10 will be used. This design provides optimal operation by including any number of ribs 22 greater than two to be in contact with the bottom of the container or package, according to container variables including container type (flexible or rigid), weight, surface area, material, and finish.
Embodiments of the center tray section 20 as disclosed herein provide additional advantages for use in retail merchandising applications. The plurality of ribs 22 are easy to clean by virtue of the ungulate wave-like concave-convex configuration of valleys 27 and ribs 22, without the presence of sharply angled corners, cracks or crevices within which dirt, spillage, or bacteria tend to be trapped. The design of embodiments provide a superior low drag surface that provides further advantages as will be described in further detail herein.

The center tray section 20 is secured to a base 12, which provides stability to the freezer tray assembly 10 and also functions support the freezer tray assembly 10 on a shelf or other supporting structure within a freezer. As shown in
Two examples of side tray sections 30 are shown in
As shown in
Still referring to
In these illustrated embodiments, the center tray section 20 has a plurality of clips 28 that secure the side tray section 30 at a discrete lateral position with respect to the center tray section 20. As shown in
In another embodiment, the side trays 30 are received within the space provided between the base 12 and the center tray section 20. The lugs 14 of the base 12 provide a spacing between the base 12 and the center tray section 20. This space is dimensioned to approximate the thickness of the side tray section 30 so that the side tray section 30 is sandwiched between the base 12 and the center tray section 20. The side tray section 30 is thus infinitely positionable laterally with respect to the center tray section 20 while the engagement of the lugs 14 of the base 12 with the notches 33 maintain alignment of the side tray section 30 and the center tray section 20 as described above.
The side tray section 30 preferably has a fence or side wall 36 that is vertically oriented and extends along a longitudinal axis of the side tray section 30. The side wall 36 helps to secure items on the freezer tray assembly 10, and to guide items as they are moved on the freezer tray assembly 10. The side wall 36 may be integral with side tray section 30, or it may be a separate, removable component.
In the embodiment shown in
In the alternative embodiment described above that includes the functionality of infinite adjustment of the width of the freezer assembly 10, two additional advantages may be observed. First, some infinitely adjustable embodiments provide an improved user experience when setting up and stocking freezer tray assemblies 10 of these embodiments. The infinitely adjustable nature of the embodiment allows the width of the freezer tray assembly to be expanded for receiving containers or packages. After the freezer tray assembly has been loaded with product, the side tray sections 30 are adjusted to a minimum or other desired width.
Secondly, other infinitely adjustable embodiments of the freezer tray assembly maximize the use of space when a plurality of freezer tray assemblies 10 are used within a freezer or across a shelf. Since the side tray sections 30 move freely with respect to the center tray section 20 in an infinitely adjustable manner, the width of the freezer tray assembly 10 can be minimized specifically to the dimensions of the products stored within the freezer tray assembly 10. This is to be contrasted with embodiments wherein the freezer tray assemblies are only adjustable incrementally. Since the increments are set to standardized spaces, a user must consistently select a larger freezer tray assembly width than is ultimately needed in order for the product to fit within the freezer tray assembly. The elimination of the incremental adjustments, allows the user to minimize the width of each freezer tray assembly to the product contained within that specific freezer tray assembly 10. Over the course of an entire freezer or shelf, this can add valuable product facings.
In an alternative embodiment, a union tray section 40 may be used between two adjacent center tray sections 20, such as in the place of one or more adjacent side tray sections 30. As shown in
The freezer tray assembly 10 of the present invention may include any desired combination of center tray sections 20, side tray sections 30 and union tray sections 40. These components are modular and interchangeable so that a specific freezer tray assembly 10 may be assembled to accommodate a variety of freezers and products. The various components of the freezer tray assembly 10 may be made of any suitable material. Preferably the components of the freezer tray assembly 10 are made from injection molded high-density polyethylene (HDPE) and, although it is understood that any other satisfactory material may be employed.
The freezer tray assembly 10 of the present disclosure accomplishes a number of desirable objectives in the retail display of frozen products. By providing a solid floor, the freezer tray assembly 10 insures that items are reliably moved forwardly toward the front of the freezer when a forwardmost item is removed. This reduces door opening times, which can result in significant savings in energy costs. The adjustable side tray sections 30 allow the freezer tray assembly to have virtually any desired width, which can accommodate the vast majority of frozen products such as frozen vegetables, frozen potato produces and frozen entrées. Adjacent freezer tray assemblies 10 can be chained together using union tray sections 40, to effectively form a unitary tray structure that can extend any desired width within a freezer. This is particularly advantageous, in that the products supported by all of the interconnected freezer tray assemblies 10 function as ballast to prevent unwanted movement of the freezer tray assemblies within the freezer. The freezer tray assembly 10 is preferably formed of a material, such as HDPE, which is capable of withstanding low temperature environments such as are found in supermarket freezers, and the construction of the freezer tray assembly 10 is such that the various pieces and parts are capable of operating in such an environment. Typically, however, the fence 21 will be formed of a clear material to provide product visibility.

In an embodiment, such as that depicted in
In an embodiment of the freezer tray assembly 10 that combines the disclosed ridges 22 and valleys 27 for reduced friction with the variable force spring 23, the result is that a smaller spring with reduced variable forces at each stage of the variable force spring cannot be used. In some embodiments, a reduction of required force of 20% or more can be achieved with this combination of structural features. The reduction of the force required in the variable force spring may be achieved by adjusting the gauge, girth, or the tightness of the coil in the coil spring.
The practical effect of this embodiment is an improved stocking and consumer experience when interacting with the freezer tray assembly embodiments. Reduced spring force improves the stocking experience as less force is required by store personnel to overcome the pusher assembly 24 in order to fill the freezer tray assembly with product. The consumer experience is also improved as the force applied by the variable force spring 23 can further be reduced such that the products are easily removed from the freezer tray assembly by the consumer. As the pusher assembly 24 places a compressive force upon the product between the pusher 24 and the fence 21, this applied force can make removal of product difficult for some consumers. Furthermore, when the last or one of the last of the products remaining in the freezer tray assembly 10 is removed by the consumer, some embodiments of freezer tray assembly can experience “snapping” wherein the coil spring 23 moves the pusher 24 into a forwardmost position, sometimes in contact with the fence 21. By minimizing the force applied to the pusher assembly 24, this experience can be minimized or eliminated.
