DETAILED DESCRIPTION OF THE INVENTION

(9) While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the description in conjunction with the drawings. As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention which can be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the inventive arrangements in virtually any appropriately detailed structure. Further, the terms and phrases used herein are not intended to be limiting but rather to provide an understandable description of the invention.

(10) As described throughout this document, the term “complementary shape,” and “complementary dimension,” shall be used to describe a shape and size of a component that is identical to, or substantially identical to the shape and size of another identified component within a tolerance such as, for example, manufacturing tolerances, measurement tolerances or the like.

(11) As described herein, the term “removably secured” and derivatives thereof shall be used to describe a situation wherein two or more objects are joined together in a non-permanent manner so as to allow the same objects to be repeatedly joined and separated. This can be accomplished through the use of any number of commercially available connectors such as opposing strips of hook and loop material (i.e. Velcro®), magnets, and/or compression fittings such as locking pins, clamps, nut/bolts, tethers (e.g., zip ties), snaps and buttons, for example.

(12) FIGS. 1-7 illustrate one embodiment of a pallet cover and transport container 10 that are useful for understanding the inventive concepts disclosed herein. In each of the drawings, identical reference numerals are used for like elements of the invention or elements of like function. For the sake of clarity, only those reference numerals are shown in the individual figures which are necessary for the description of the respective figure. For purposes of this description, the terms “upper,” “bottom,” “right,” “left,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention as oriented in FIG. 1.

(13) As shown in FIGS. 1 and 2, the container 10 can include a generally rectangular-shaped body having an open bottom end 11, a closed top end 12, and a plurality of side walls 13, 14, 15 and 16 that define a hollow interior space. As the container is designed to be used with commercial shipping pallets, the open bottom end 11 will preferably include dimensions that are complementary to the dimensions of a shipping pallet. Optional handles 17 can be provided along the outside of the container to aid in manual lifting of the same.

(14) In various embodiments, the top end 12 of the container 10 can be flat. Owing to the rigid structural support provided by the side and top walls of the container when secured to a pallet, the inclusion of a flat top allows a user to stack a second pallet of material vertically onto the first pallet and container. Such a feature advantageously allows a shipper to utilize all vertical space in a trailer which is typically not able to be utilized.

(15) In other embodiments, the top end of the container can include a pitched or non-flat shape so as to explicitly prevent stacking. Such a feature being particularly advantageous when shipping volatile or hazardous materials, for example. In either instance, any number of channels can be positioned along the main body of each container so as to receive metal strapping bands for securing multiple pallets and/or containers together during transport.

(16) In the preferred embodiment, the side walls can be tapered wherein the dimension of the container along the open bottom end is greater than the dimension of the container along the closed top end 12. Such a feature allowing multiple empty containers to be stacked inside each other so as to reduce the space required to store the containers when not being used.

(17) As described herein, the container 10 can be constructed from any number of different materials and can include any number of different shapes and sizes. In the preferred embodiment, the container can be constructed from recycled plastic so as to be lightweight, resistant to water, and environmentally friendly. In some embodiments, the plastic material may be blended or lined with fire retardant additives so as to be used in the transportation of hazardous materials. In another embodiment, the container can be insulated—either through incorporation of insulation within the plastic construction or by having a cloth blanket liner, for example. The ability to independently insulate an entire pallet of materials advantageously prevents damage to sensitive components that are temperature sensitive.

(18) Of course, other embodiments are contemplated wherein the container may be constructed from other materials that are, for example, relatively strong and stiff for their weight. Several nonlimiting examples include but are not limited to various metals or metal alloys (e.g., aluminum, steel, titanium, or alloys thereof), plastic/polymers (e.g., high-density polyethylene (HDPE), rigid polyvinyl chloride (PVC), or polyethylene terephthalate (PET)), and/or various composite materials (e.g., carbon fibers in a polymer matrix, fiberglass, etc.). Moreover, each container may be manufactured to include any number of different markings or colors, so as to designate the contents or class of contents secured within the container.

(19) In one embodiment, a first plurality of grooves 21 can be positioned along the bottom edges of one or more of the side walls 13-16. Each of the grooves 21 can include complementary dimensions and locations as the channels found on a shipping pallet so as to allow the same to be engaged by the forks of a forklift. To this end, the grooves along side walls 13 and 15 can be separated by a first distance D1, and the grooves along the side walls 14 and 16 can be separated by a second distance D2. Depending on the shape of the container 10, distances D1 and D2 can be identical or different.

(20) As shown best in cutout FIG. 3, one embodiment of the container 10 can include one or more connectors 30 that can be positioned along the bottom ends of one or more of the side walls 13-16. In the preferred embodiment, each connector 30 can include a body section 31 that is permanently secured to the wall of the container 10. A hollow channel 32 is positioned along the bottom end of the body, and a planar shaft 33 can slide through the channel. When the shaft is in the closed position (i.e., slid fully into the channel) the shaft body will be positioned under the top surface of the pallet so as to prevent the cover from being removed.

(21) In one embodiment, apertures 34a and 34b can be positioned along the channel 32 and the shaft 33. When the shaft is in the closed position, the apertures can be aligned so as to receive a lock or other such device thereby preventing the connector from being opened or removed by an unauthorized person. Of course, the container is not limited to the use of any particular type of connector, as any device capable of removably securing the bottom of the container to a pallet is also contemplated.

(22) FIGS. 4 and 5 illustrate one embodiment of the container 10 in operation. As shown, a container 10 can be manually lifted and positioned so that the open bottom end 11 is directly above a pallet 1 that is loaded with materials 5. The materials may be stacked onto the pallet without shrink wrap or may include only one layer of shrink wrap.

(23) Next, the container can be lowered over the pallet assembly so that the top 12 and side surfaces 13-16 surround the pallet and materials. When so positioned, each of the grooves 21 will be aligned with the channels 2 of the pallet 1 so that a forklift can be used in the normal manner to lift and move the pallet. Additionally, once the cover is secured onto the pallet, the connector 30 can be locked as described above so as to prevent separation of the cover from the pallet.

(24) FIG. 6 illustrates one embodiment of the container 10 that further includes a plurality of protrusions 61 that are positioned along the closed end 12 of the container. The protrusions forming a second plurality of grooves 22 which can include complementary dimensions and/or locations as the grooves 21 described above. Additionally, grooves 22 can be positioned so as to interlock with grooves 21 when two containers 10 are stacked, thus eliminating the need for the pallet banding described above.

(25) As shown in FIG. 7, the second set of grooves 22 can function to directly receive the forks 6 of a forklift when the container is in an inverted position. Such a feature allowing a shipper to fill the interior portion of the container 10 with any number of different materials so as to utilize the container as a storage or shipping box when not secured to a pallet.

(26) As noted above, the container 10 is designed to be used with palletized materials. As such, in one preferred embodiment, the open bottom end 11 can include a width (e.g., distance between side walls 14 and 16) of 40 inches, and a length (e.g., distance between side walls 13 and 15) of 48 inches, so as to be complementary in shape and size to standard shipping pallets having the same dimensions. Likewise, the height (e.g., distance between elements 11 and 12) of each of the side walls 13-16 can be 60 inches, so as to conform to international freight dimensions of 60 inches. Of course, other embodiments are contemplated wherein the container is manufactured to include dimensions different than those described above. Such features being beneficial for manufacturer of items who routinely ship products having non-conforming dimensions.

(27) Although described above for use with existing shipping pallets, other embodiments are contemplated wherein the container is provided with a new shipping pallet that is constructed for use specifically with the above described container system.

(28) Accordingly, the above noted container advantageously functions to ensure that palletized materials are protected from theft, adverse weather conditions and damage caused from forklifts and other such equipment.

(29) As described herein, one or more elements of the container 10 can be secured together utilizing any number of known attachment means such as, for example, screws, glue, compression fittings and welds, among others. Moreover, although the above embodiments have been described as including separate individual elements, the inventive concepts disclosed herein are not so limiting. To this end, one of skill in the art will recognize that one or more individually identified elements may be formed together as one or more continuous elements, either through manufacturing processes, such as welding, casting, or molding, or through the use of a singular piece of material milled or machined with the aforementioned components forming identifiable sections thereof.
