BACKGROUND OF THE INVENTION
[0001] 1. Technical Field
[0002] This invention generally relates to storage materials. More
particularly, the invention relates to storage boxes made from
corrugated cardboard. Specifically, the invention relates to
corrugated cardboard storage boxes that have protective materials
incorporated therein.
[0003] 2. Background Information
[0004] Offices and individuals frequently need to store materials
such as files and papers for long periods of time. Typically, these
materials are placed in some sort of storage box for safekeeping.
These boxes may take a variety of forms including plastic tubs or
corrugated cardboard boxes with lids. Plastic tubs are convenient
and protect the materials stored therein from dangers such as
liquid exposure, but can be relatively expensive if large volumes
of materials need to be stored. Cardboard boxes on the other hand
are inexpensive and convenient, but they are vulnerable to dangers
such as water damage, fire, insects and mold.
[0005] There is therefore a need in the art for an improved
corrugated cardboard box that is less vulnerable to threats that
may damage the contents of the box.
SUMMARY OF THE INVENTION
[0006] The device of the present invention comprises a cardboard
box for protectively storing perishable paper products that
includes protective materials that protect the box and its contents
from any of a number of threats including water damage, fire
damage, insects, mold and fungi. The box comprises a bottom wall,
side walls and a lid that surround and define an interior cavity in
which the paper products are stored. Each of the bottom wall, side
walls and lid are made from cardboard. Protective materials are
applied to one or more of the bottom wall, side walls and lids by
either impregnating the cardboard with a suitable chemical,
applying a film over the cardboard or spraying a coating thereover.
Suitable chemicals that produce the desired properties include, but
are not limited to wax, oil, plastic, polybrominated diphenyl
ether, polybrominated biphenyl, brominated cyclohydrocarbons, boric
acid and hydrogen peroxide.

DETAILED DESCRIPTION OF THE INVENTION
[0016] FIGS. 1 and 2 show a corrugated cardboard box 10 known in
the prior art. Box 10 has a bottom wall (not shown) and four side
walls 12 that define an interior cavity 14 for holding a plurality
of files or papers 16. A lid 18 is provided for closing off access
to cavity 14. Lid 18 may take any one of a number of different
forms, such as four panels as shown in FIG. 1, or a single panel
(not shown) or a completely separate lid unit (not shown. The
bottom wall, side walls 12 and lid 18 are all made from corrugated
cardboard. As shown in FIG. 2, the side wall 12 comprises two
planar sheets 20, 22 which sandwich a corrugated cardboard sheet 24
thereinbetween. The cardboard used in box 10 is vulnerable to water
damage, fire damage, may permit mold to grow thereon if it is
subjected to high moisture environments and is susceptible to
paper-eating insets such as silverfish and the like.
[0017] FIGS. 3-5 show a storage box in accordance with the present
invention and generally indicated at 50. Box 50 is similarly formed
to box 10 in that it has a bottom wall (not shown), side walls 52
that surround and define an interior cavity 54 for holding a
plurality of files or papers 56 therein. A lid 58 is provided for
closing off access to cavity 54. Lid 58 shown in FIG. 3 comprises
four panels that are secured together with an adhesive tape of the
like. It will be understood by those skilled in the art that the
shape, size and configuration of box 50, as shown in the attached
drawings, is by way of illustration only. Any shape, size and
configuration of the box and lid may be used without departing from
the spirit of the present invention.
[0018] In accordance with a specific feature of the present
invention, each of the bottom wall, side walls 52 and lid 58 of box
50 are manufactured from a corrugated cardboard that has been
specially treated with one or more of several protective materials
as will are hereinafter described.
[0019] Referring to FIG. 4, there is shown a portion of side wall
52 comprising a first and a second planar sheet 60, 62 of cardboard
which sandwich a corrugated sheet 64 of cardboard thereinbetween.
It will be understood by those skilled in the art, that the bottom
wall, side walls 52 and lid 58 of box 50 may be made up from any
number of a plurality of planar and corrugated sheets that are
layered and bonded together to form a unitary member of the
required strength, without departing from the spirit of the present
invention. The following illustrations show a box wall 52 made from
two planar sheets and one corrugated sheet for the sake of clarity
only. FIG. 4 illustrates a first embodiment of the side wall 52 in
which one or more of sheets 60, 62 and 64 are impregnated with a
protective material as will be hereinafter described.
[0020] FIG. 4A shows a second embodiment of side wall 152 that
includes a layer of protective material 166 therein. In this
instance, layer 166 is applied over second sheet 162 and, because
second sheet 162 forms the exterior surface of side wall 152,
protective layer 166 forms the external surface of the storage
box.
[0021] Referring to FIG. 4B, there is shown a third embodiment of a
side wall of the box, being generally indicated at 252. Side wall
252 comprises first and second planar sheets 260, 262 of cardboard
which sandwich a corrugated layer 264 thereinbetween. Protective
layer 266 is applied over first sheet 260 and thus forms the
interior surface of the box in accordance with the present
invention.
[0022] Referring to FIG. 4C, there is shown a fourth embodiment of
a side wall for the box, being generally indicated at 352. Side
wall 352 comprises first and second planar sheets 360, 362 of
cardboard which sandwich a corrugated layer 364 thereinbetween. A
first protective layer 366 is applied over sheet 362 and a second
protective layer 368 is applied over sheet 360. The protective
layers 366, 368 therefore form both the exterior and interior
surfaces of the box.
[0023] Referring to FIG. 5, there is shown a fifth embodiment of a
side wall for the box, being generally indicated at 452. Side wall
452 comprises first and second planar sheets 460, 462 of cardboard
which sandwich a corrugated layer 464 thereinbetween. A protective
layer 466 is applied over second sheet 462 and another planar sheet
of cardboard 470 is applied over protective layer 466. Thus,
protective layer 466 is sandwiched between two layers of untreated
cardboard.
[0024] In accordance with one of the specific features of the
present invention, one or more layers of the bottom wall, side
walls 52 and lid 58 of box 50 include protective materials that
impart improved protective properties to the storage box 50. In a
first instance, shown in FIG. 4, any or all of sheets 60, 62 and 64
may be impregnated with a protective material. Thus, any and all of
sheets 60, 62 and 64 constitute a protective layer of box 50.
[0025] With reference to FIGS. 4A-5, the protective layer will be
referred to in the following description as layer 66 for the sake
of clarity, but it will be understood that any and all of the
protective layers 66, 68 through to 466 includes one or more
protective materials that impart improved protective properties to
the storage box. Protective layer 66 may be one of a planar or
corrugated sheet of cardboard that is impregnated with the
protective material. Alternatively, protective layer 66 may
comprise a film that is bonded onto a planar sheet of cardboard.
Furthermore, protective layer 66 may constitute a separate thin
film. Finally, protective layer 66 may constitute a powder or
liquid coating that is sprayed or otherwise deposited onto one of
the sheets in the box.
[0026] The protective layer 66 may constitute cardboard that is
impregnated with a chemical that renders that layer water
impervious or water repellant. The chemical may render the layer
fire resistant or fire retardant. The chemical may be a fungicide
that prevents mold from growing, or a pesticide that kills insects
such as silverfish or that repels such insects because of an odor
or taste associated therewith. A wide variety of chemicals are
known to produce these properties, but have not been previously
applied to corrugated cardboard or have not been applied in
combination with each other to cardboard. So, for instance, a wide
variety of chemicals and chemical components may be used for these
purposes, These include, but are not limited to, a wax, or an oil
may be impregnated into the layer, or a plastic film may be used to
create a water repellant or resistant layer. Chemicals such as
aluminum hydroxide and diammonium phosphate, polybrominated
diphenyl ether, polybrominated biphenyl or brominated
cyclohydrocarbons can be sprayed or otherwise applied to a one of
the layers 60, 62 or a separate cardboard sheet in order to create
a fire retardant layer. Boric acid or hydrogen peroxide may be used
in layer 66 to act as a pesticide or fungicide. So, for example, in
FIG. 4, one or more of sheets 60, 62 and 64 may be impregnated with
a suitable insecticide to repel insects such as silverfish from box
50. Or, in FIG. 4A, layer 166 of a suitable fire-regardant chemical
may be applied over the outer sheet 162 of the box. Or, in FIG. 4B,
a fungicide may be applied as layer 268 over the interior sheet 260
of the box. Or, in FIG. 4C, layer 366 may be a suitable water
repellant and layer 368 may be a fire retardant. Or, in FIG. 5, a
fire-retardant layer 466 may be sandwiched between two sheets 462,
470 of cardboard.
[0027] It will be understood by those skilled in the art that one
or more or all of these and other chemical compounds may be applied
to the cardboard in one or more layers in order to protect the box
from one or more of water, fire, insects and mold. Furthermore, any
other chemical or substance may be applied to the interior or
exterior of box 50, or may be impregnated into the cardboard layers
thereof in order to give the materials thereof the protective
qualities that are desired.
[0028] In the foregoing description, certain terms have been used
for brevity, clearness, and understanding. No unnecessary
limitations are to be implied therefrom beyond the requirement of
the prior art because such terms are used for descriptive purposes
and are intended to be broadly construed.
[0029] Moreover, the description and illustration of the invention
are an example and the invention is not limited to the exact
details shown or described.
