The present invention relates to a system for stacking archive boxes; more particularly, the present invention relates to a system for stacking at least one archive box on top of another archive box, wherein each archive box includes a fire-resistant drywall support shell that protects the contents being stored therein from fire damage, while at the same time reducing the chance that the lower archive box will collapse under a load imposed by the archive boxes stacked thereon.
Archive boxes are used to store documents, files, office supplies, and other valuable items. An archive box typically includes a bottom container portion and a lid, which may be formed of cardboard or plastic. The bottom container portion is typically filled with items, the lid is placed on top of the bottom container portion to enclose the items within the archive box, and then the archive box placed in storage so that it may be accessed at a later date. It is not uncommon for archive boxes to remain in storage without being accessed for a long period of time.
As archive boxes are placed in storage, they are ordinarily stacked on top of on another in order to conserve storage space. However, due to the cumulative weight of the items contained within the archive boxes being stacked, the bottom-most archive boxes are susceptible to being crushed over time, thereby risking damage to the items contained within those particular boxes. Most existing archive boxes fail to provide adequate structural rigidity to support heavy loads over an extended period of time. In addition, the inadequate thermal resistance of existing archive boxes is a concern in the instance of a fire. The heat produced by a fire will rapidly burn a cardboard archive box and melt a plastic archive box, thereby exposing the items contained within those boxes to high temperatures leaving little opportunity to save the items from being destroyed by the fire.
As such, there is a need for system for stacking archive boxes that will reduce the possibility of the bottom-most archive boxes from being crushed. There is also a need for a system for stacking archive boxes that will also adequately protect the items contained within the archive boxes in the event of a fire. The present invention addresses these needs as well as other needs.
In order to overcome the above stated problems and limitations herein is provided a system for stacking two or more archive boxes on top one another. The archive boxes included in the system comprise an outer shell, an inner shell disposed within said outer shell, a drywall support shell, and a lid. The inner shell has an opening defining a storage compartment, and is spaced apart from the outer shell to form a cavity therebetween. The inner shell also includes a bottom wall and at least one side wall. The drywall support shell is disposed within the cavity and surrounds a substantial portion of the inner shell. The drywall support shell includes a bottom wall positioned adjacent to the bottom wall of the inner shell, and at least one side wall positioned adjacent to the at least one side wall of the inner shell. The lid is configured to be disposed over the opening in the inner shell to selectively enclose the storage compartment. The at least one side wall of the drywall support shell of a first archive box is substantially aligned with the at least one side wall of the drywall support shell of a second archive box whereby the second archive box is supportive of the first archive box.
The system may also be configured so that the at least one side wall of the first archive box is coplanar with the at least one side wall of the second archive box. Further, the first archive box may include at least one support foot extending from the outer shell, and the second archive box may include an indentation in the lid configured for receiving the at least one support foot to properly orient the first and second archive boxes relative to one another.
The bottom wall of the inner shell of each of the archive boxes may include an outer surface, wherein at least one first rib extends outwardly from the outer surface. The at least one first rib is in contact with the bottom wall of the drywall support shell to off-space the bottom wall of the drywall support shell from the outer surface of the bottom wall of the inner shell. The at least one side wall of the inner shell of each of the archive boxes may include an outer surface, wherein at least one second rib extends outwardly from the outer surface. The at least one second rib is in contact with the at least one side wall of the drywall support shell to off-space the at least one side wall of the drywall support shell from the outer surface of the at least one side wall of the inner shell.
The outer shell of each of the archive boxes may include a bottom wall and at least one side wall. The bottom wall of the outer shell of each of the archive boxes may include an inner surface, wherein at least one third rib extends outwardly from the inner surface. The at least one third rib is in contact with the bottom wall of the drywall support shell to off-space the bottom wall of the drywall support shell from the inner surface of the bottom wall of the outer shell. The at least one side wall of the outer shell of each of the archive boxes may include an inner surface, wherein at least one fourth rib extends outwardly from the inner surface. The at least one fourth rib is in contact with the at least one side wall of the drywall support shell to off-space the at least one side wall of the drywall support shell from the inner surface of the at least one side wall of the outer shell.
Each of the archive boxes may further include a thermal reflectant layer, such as, for example, aluminum foil or stainless steel, that surrounds a substantial portion of the drywall support shell, wherein the metallic barrier is positioned between the drywall support shell and the outer shell to reflect heat produced in the event of a fire.
The lid on each of the archive boxes may include a lid bucket defining a fill cavity, a cover coupled with the lid bucket to enclose said fill cavity, and fire-resistant insulation positioned within the fill cavity. The lid bucket may include a bottom wall having at least one fill protrusion extending therefrom. The cover may include an inner surface having at least one brace protrusion extending therefrom positioned to contact the at least one fill protrusion on said lid bucket to increase the rigidity of the lid. Further, the inner surface of the cover may include at least one snap protrusion extending therefrom, wherein the lid bucket includes at least one receiving slot defined therein configured to receive the snap protrusion to fasten the cover to the lid bucket.
In another aspect, there is provided a system for stacking a first archive box on top of a second archive box, wherein the first and second archive boxes each comprise an outer shell, an inner shell, a drywall support shell, a thermal reflectant layer, and a lid. The outer shell includes a bottom wall and at least one side wall, the outer shell including at least one support foot extending therefrom. The inner shell includes a bottom wall and at least one side wall, the inner shell disposed within the outer shell and having an opening defining a storage compartment. The inner shell is spaced apart from the outer shell and defines a cavity between the inner shell and the outer shell. The drywall support shell is disposed within the cavity and surrounds a substantial portion of said inner shell, The drywall support shell includes a bottom wall spaced apart from the bottom wall of the inner shell and the bottom wall of the outer shell. The drywall support shell includes at least one side wall that is spaced apart from the at least one side wall of the inner shell and the at least one side wall of the outer shell. The at least one side wall of the drywall support shell includes an end portion, the bottom wall of the drywall support shell includes a top surface, wherein the end portion is in contact with the top surface. The thermal reflectant layer surrounds either all, or a substantial portion, of the drywall support shell and is positioned between the drywall support shell and the outer shell. The lid is configured to be disposed over the opening in the inner shell to selectively enclose the storage compartment. The lid also has an indentation defined therein configured for receiving the at least one support foot of the first archive box. The at least one side wall of the drywall support shell of the first archive box is substantially vertically aligned with, or positioned inwardly of, the at least one side wall of the drywall support shell of the second archive box whereby the second archive box is supportive of the first archive box.
A further aspect of the invention includes a system for stacking a first archive box on top of a second archive box, wherein the first archive box and the second archive box each comprise an outer shell including a bottom surface, an inner shell disposed within the outer shell, a drywall support shell, and a lid. The inner shell has an opening defining a storage compartment, and is spaced apart from the outer shell thereby defining a cavity between the inner shell and the outer shell. The inner shell includes a bottom wall and first and second opposing side walls. The drywall support shell is disposed within the cavity and surrounds a substantial portion of the inner shell. The drywall support shell includes a bottom wall positioned adjacent to the bottom wall of the inner shell, and at least first and second opposing side walls positioned adjacent to the first and second opposing side walls of the inner shell, respectively. The lid is configured to be disposed over the opening in the inner shell to selectively enclose the storage compartment. The bottom surface of the outer shell of the first archive box is in contact with the lid of the second archive to form at least one load transmission point that is positioned inwardly of the first and second opposing side walls of the drywall support shell of the second archive box whereby the second archive box is supportive of the first archive box.

When inner shell 26 is disposed within outer shell 22, inner shell 26 is spaced apart from outer shell 22 so that a drywall support shell 28 may be disposed within a cavity 60 defined between inner shell 26 and outer shell 22. As such, drywall support shell 28 would be inserted into outer shell 22 prior to inner shell 26 being inserted within opening 34 of outer shell 22. In the event of a fire, the temperature of outer shell 22 would likely increase to a level where it loses the ability to protect the contents contained within outer shell 22. Therefore, drywall support shell 28 is configured to surround at least a substantial portion of inner shell 26 to protect the contents contained within storage compartment of archive box 10 for a period of time in the event of a fire.
Drywall support shell 28 may include a bottom wall 62 positioned adjacent to and between bottom walls 30, 46 of inner and outer shells 22, 26. Drywall support shell 28 may also include at least one side wall 64 positioned adjacent to and between side walls 32, 48 of inner and outer shells 22, 26. It should be understood that bottom wall 62 and side walls 64 may either be separate pieces or one single integral piece. Further, bottom wall 62 is preferably positioned perpendicular with respect to each of the at least one side wall 64. As best seen in

The bottom wall 62 and/or at least one side wall 64 may be formed of gypsum board drywall, such as, for example, GOLD BOND® Gypsum Board manufactured by National Gypsum Company, 2001 Rexford Road, Charlotte, N.C. 28211. The gypsum board drywall may include an outer paper layer 74, an inner paper layer 76, and a core 78 including gypsum disposed between the outer and inner paper layers 74, 76. The core 78 may be formed from gypsum plaster, which is the semi-hydrous form of calcium sulfate (CaSO4.½H2O). Depending on the type of properties that are desired for core 78, when forming the gypsum board, the plaster may be mixed with fiber (e.g., paper, fiberglass), plasticizer, foaming agent, gypsum crystal, starch, and other additives that increase mildew and fire resistance. One or more of bottom wall 62 and at least one side wall 64 preferably have a thickness of about 0.5 inches, but it will be understood that other thickness may also be used depending on the amount of fire resistance that is desired and the desired weight of archive box 10.

Instead of, or in addition to, using thermal reflectant layer 80 to protect drywall support shell 28 in the event of a fire, an intumescent coating 81 may be sprayed, brushed, rolled, or otherwise applied to all, or part, of an outer surface of drywall support shell 28, as best seen in
As mentioned above, archive box 10 may further include a lid 14 that is configured to be disposed over opening 50 in inner shell 26 of base assembly 12 to selectively enclose storage compartment 18. As best seen in

Archive boxes 10a, 10b are oriented relative to one another so that side walls 64a of drywall support shell 28a of archive box 10a are substantially vertically aligned with the corresponding side walls 64b of drywall support shell 28b of archive box 10b. For example, with reference to
In the case where support feet 20a are used on the upper archive box 10a, the point of contact between upper archive box 10a and lower archive box 10b is the interface between support feet 20a and cover 98b, which is hereby identified as the load transmission point 112 (
The system of stacking archive boxes as described above provides a number of advantages. For example, each of the archive boxes that are used in the above-referenced system comprise a base assembly including a drywall support shell and a lid including thermally resistant insulation material, and therefore provide extended protection to contents stored within each archive box in the event of a fire. In addition, the orientation of the drywall support shell in each of the stacked archive boxes allows for a transfer of load from the upper archive box to the lower archive box, which prevents the premature collapse of the lower archive box in the event of a fire, thereby protecting the contents located within the lower archive box. Furthermore, the use of support feet on the upper archive box which are configured to be disposed in indentations formed in the lid of the lower archive box provides proper alignment of the upper archive box relative to the lower archive box, which in turn results in the lower archive box sustaining its structural integrity for a lengthened period of time in the event of a fire.
