OVERWRAP PAD TRAY
A tray to support a plurality of containers includes a base portion, a first pair of opposing side walls extending upwardly from the base portion, and a second pair of opposing side walls extending upwardly from the base portion and interconnecting the first pair of opposing side walls to form a shallow tray body. The first and second pairs of opposing side walls have non-linear profiles to conform to outer contours of the containers. A sheet of plastic is wrapped around the containers and tray body to securely hold the containers within the tray.
This application claims priority to U.S. Provisional Application No. 61/221,136, filed Jun. 29, 2009, and U.S. Provisional Application No. 61/251,327, filed Oct. 14, 2009.
TECHNICAL FIELDThe present invention relates to a plastic pad tray that supports, stores, and transports beverage containers, such as bottles for example, in an overwrap configuration.
BACKGROUND OF THE INVENTIONPlastic bottles are widely used as containers for beverages such as soft drinks, juice, water, etc. These bottles are often stored and transported in a shallow cardboard box with a plastic overwrap extending underneath the box and around the top of the bottles to securely hold the bottles in the box. The cardboard box includes a bottom surface and first and second pairs of opposing side walls that cooperate to form a shallow cavity. The bottles are placed with the cavity and then are wrapped by a plastic sheet of material to secure the bottles in place. While the cardboard box provides one known inexpensive packaging solution, even more inexpensive solutions are continually being sought.
SUMMARY OF THE INVENTIONA tray to support a plurality of containers includes a base portion, a first pair of opposing side walls extending upwardly from the base portion, and a second pair of opposing side walls extending upwardly from the base portion and interconnecting the first pair of opposing side walls to form a shallow tray body. The first and second pairs of opposing side walls have non-linear profiles to conform to outer contours of the containers.
In one example, the base portion and first and second pairs of opposing side walls are comprised of a single sheet of material. In one example, the single sheet of material comprises a molded plastic body.
The base portion includes a plurality of pockets where each pocket is to receive one container. In one example, each pocket includes a locating feature to locate the container within the pocket. A sheet of plastic material is wrapped around the containers and tray body to securely hold the containers within the pockets.
These and other features of the present invention can be best understood from the following specification and drawings, the following of which is a brief description.
A pad tray 10 according to the present invention is shown in
A top perspective view of the pad tray 10 is shown in
The base portion 18 is configured to include a plurality of shallow pockets 24 that are discretely located relative to each other. Each pocket 24 defines a location for one beverage container 12. Each pocket 24 includes a flat surface portion 26 and a curved wall portion that extends upwardly around the flat surface portion 26 to form the respective pocket 24. The curved wall portions include the opposing side walls for side and corner pockets. The flat surface portion 26 includes a raised circular disc portion 26a extending upwardly from the flat surface portion 26. The raised circular disc portions 26a provide support for the bottle sitting within the associated pocket 24 and reduce the possibility of the containers bouncing relative to the pad tray 10, which could occur during transport. The circular disc portions 26a also provide locating features such that each beverage container 12 is properly located and retained within an associated pocket 24.
In between adjacent rows of pockets 24, a plurality of supports 28 are formed as part of the pad tray 10. In the example shown, six supports 28 are formed as part of the pad tray 10. The supports 28 help to prevent the pad tray 10 from flexing near the center where less structural support is provided by the side walls 20, 22. The supports 28 are comprised of a raised boss portion 30 that extends upwardly from the base portion 18 at a center location between groups of four pockets 24. The raised boss portion 30 includes curved side walls that form a portion of pocket walls for the centrally located pockets.
The raised boss portion 30 includes an upper surface 32 having a recess 34 (
Also as shown in
For the pockets 24 at the corners, this protruding lip portion 44 extends around a significant portion of the outer circumference of the pocket 24, i.e. extends around more than 50% of the outer circumference. For the remaining pockets along the side walls 20, 22, the protruding lip portion extends less than 50% around the outer circumference. Further, in the example shown, the protruding lip portions 44 for these remaining pockets are positioned radially inward and closer to a center of the respective pocket 24 (as indicated at 48) in comparison to the protruding lip portions 44 for the corner pockets 24, which is best shown in
Also as shown in
In this example, the centrally located pockets 24′ include protruding ribs or lip portions 64 (
In this example, the side pockets 24′ also include protruding lip portions 44′ that are similar to those described above with regard to
Also, as shown in
In this example, a bottom surface of the pad tray 10″ includes protruding ribs 70 (
Each of the ribs 70, which extend downwardly from a bottom surface of the pad tray 10″ as shown in
The pockets 24″ along the side walls 20, 22 also include protruding lip portions 44″ that are similar to those described above with regard to
Also, as shown in
In one example, the pad trays 10, 10′, 10″ comprise a plastic or other similar material that is molded as a very thin sheet of material into any of the configurations described above. Any type of molding process can be used to form the pad tray, such as by injection molding for example. The result is a very thin, plastic pad tray that provides a cost savings over cardboard boxes previously utilized to transport and store beverage containers, while still providing adequate strength and stiffness for supporting the containers.
In accordance with the provisions of the patent statutes and jurisprudence, exemplary configurations described above are considered to represent a preferred embodiment of the invention. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
Further, although a preferred embodiment of this invention has been disclosed, a worker of ordinary skill in this art would recognize that certain modifications would come within the scope of this invention. For that reason, the following claims should be studied to determine the true scope and content of this invention.
