The present application is a continuation-in-part of U.S. patent application Ser. No. 11/665,762 which is the U.S. National Stage Application under 35 U.S.C. 371 of International Application No. PCT/US2005/009400, which is the non provisional of U.S. Patent Application Ser. No. 60/554,559 filed Mar. 18, 2004, the disclosures of which are incorporated herein by reference in their entirety.
BACKGROUND OF THE INVENTIONThe present invention is broadly directed to containers. Particularly, the present invention is directed to shipping containers useful for transporting parcels between senders and recipients. More specifically, the present invention is directed to reusable shipping containers suitable for shipping expensive or fragile item(s) that may comprise separate parts or components.
There are a wide variety of containers useful for holding, storing, and shipping goods. Such containers include a large variety of tote containers, cartons, and boxes, all of which are known in the art and each having particular features that make the container suitable for desired applications. Containers are commonly used, for example, in the shipping industry. Indeed, there is a fundamental need for containers in commerce-based societies so that goods may be shipped from merchant to customer.
Perhaps the most common type of container employed by the shipping industry is a one-time use only carton constructed, for example, of paperboard. The item to be shipped is placed within the interior of the carton that is filled with cushioning materials, such as styrofoam “peanuts”, shredded paper or other paper based filler, to name a few Thereafter, the carton is sealed with packaging tape, staples, twine or similar mechanism. Once the carton reaches its shipping destination, the recipient typically discards both the container and the cushioning materials.
There are several noteworthy deficiencies associated with the shipping industry's use of one-time use only cartons. First, since the cartons are not constructed of a rigid material, such as corrugated plastic or sheet metal, shippers have been conditioned to excessively cushion items to protect them during shipping. Such excessive packaging leads to increased packing costs and an inefficient use of the parcel carrier's space. Wasted space reduces the volume of shipping capacity of carriers, be it air transport or land-based transport, such as trucks. Second, there is a substantial time investment in packaging that results from the need to carefully pack and seal the paperboard carton and prepare the shipping documents for the same. Third, in addition to the problem of cost, packing waste is one of the leading contributors to landfill waste today. The detriment to the environment is only expected to worsen with the continued rise in internet-driven commerce.
One possible solution that the shipping industry could employ to remedy the deficiencies created by the use of cardboard cartons is to adopt a more highly durable container that is reusable and makes efficient use of the carrier's available space. One such container having both of these characteristics and that is being used for limited shipping needs is commonly referred to as a tote box.
Generally, tote boxes are substantially rigid containers that provide for the safe transportation and storage of goods. Typically, tote boxes are designed to have tapered sides so that the tote boxes can be stacked or mounted in a nested relationship with other tote boxes of the same construction. The ability to stack multiple tote boxes on top of each other makes efficient use of space during the transportation and storage of goods. As a result, many tote boxes are constructed of a rigid material, usually corrugated plastic or sheet metal, to support the weight of a plurality of tote boxes. In addition, many tote boxes are further constructed to include a top rail or rim that is adapted to receive the bottom of another tote box.
Unfortunately, the use of conventional tote boxes, with few exceptions, has not easily translated into a viable use for the shipping industry, due perhaps to various drawbacks associated with their construction. For example, tote boxes are typically constructed as open-top, thin-like containers and therefore usually lack a closure or lid. In addition, tote boxes are typically constructed so as to have two (2) handle hold openings to facilitate lifting and carrying the tote. Depending upon their construction, the hand hold opening may permit intrusion of dirt, dust or even water into the interior of the tote box, which may harm or otherwise destroy the shipping item. Yet another deficiency inherent in the design of the conventional tote box is its inability to efficiently adapt for use with items of varying sizes and dimensions. For example, conventional tote boxes used to package items with conventional cushioning materials, such as those identified above, may result in excessive use of cushioning materials for relatively small items or, perhaps even worse, an insufficient amount of cushioning materials resulting in empty space. Empty space within a rigid container would permit the item to shift therein possibly resulting in damage to the item or its loss altogether.
There has long been a need for strong, relatively inexpensive, reusable shipping containers that provide for the safe transit of items and that also provide for efficient use of the carrier's available space. Such a need is somewhat met by use of conventional tote containers, and only then, for very limited shipping needs. Accordingly, a need remains for a versatile, reusable shipping container that overcomes the deficiencies of a conventional tote box. More particularly, a need remains for a shipping container that is space efficient, provides an effective cushioning environment for the item(s) inside, regardless of their size and dimension, and which is capable of widespread use for a variety of shipping needs. It is, therefore, desirable to provide a new and improved shipping container and shipping system which eliminates shifting of contents during transit, is quicker to pack versus traditional boxing and taping, avoids the risk of components contacting one another during shipment, and is recyclable. A container which is constructed to address one or more, or a combination, of such needs would be beneficial. Of particular benefit also would be a shipping container which is suitably adapted for the packaging and shipment of high value and/or fragile item(s). Further, a need remains for an alternative type of packing material which can be used in a reusable shipping container, wherein the packing material itself is reusable and constructed to facilitate the filling of void spaces within the shipping container to provide a more secure packing environment for the shipped item(s).
SUMMARY OF THE INVENTIONTo address the above needs, provided is a reusable shipping container adapted to receive one or more items for shipment from a sender to an intended recipient. The reusable shipping container is capable of withstanding the rigors associated with shipping parcels in commerce, particularly when the shipping items are fragile or expensive. Advantageously, the shipping container may be packed with usable cushioning materials to accommodate the contents of varying configurations. The ability to manipulate the reusable cushioning materials to conform, as needed, to the dimensions of the selected contents permits the size of the shipping container to be standardized, if the industry so desires. Further, if desired, customized packing solutions, which are beginning to be used with some frequency, can be modified as described herein so as to be used with the reusable cushioning materials to ensure that the items are packed in a manner to reduce the risk of damage or loss of the product.
From the description to follow it will be appreciated that the present invention is also directed to a shipping container ensemble for use in the shipping industry, as well as an improvement to a shipping container which incorporates one or more packing accessories. Also described is a method for preparing a container for shipment.

A second exemplary embodiment of a packing accessory 20 is shown in
With reference to
With the above in mind and with continued reference to
Left and right handles 36(1) and 36(2), respectively, are provided to facilitate lifting and transport, and container includes a hinged lid 38 having egg crate polyurethane foam 39 adhered thereto. Associated with lid 38 is a closure mechanism designed to be a flush mounted closure utilizing left and right ¼ turn bolts 31(1) &31(2) and associated left and right keepers 33(1) & 33(2), as available from Southco Inc. of Condordville, Pa. It is preferred to have a recessed design as shown to eliminate snag hazards. This design is a preferred replacement to the buckles & strap design described in co-pending application Ser. No. 60/554,559 because the buckle/strap is a surface mounted arrangement and both items can become catch hazards when the container travels through the sort equipment in the parcel hubs.
