Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation-in-part application that
claims the benefit of the filing date of the U.S. application
entitled "CELLULOSE BASED RECYCLABLE CONTAINER," filed on Apr. 13,
2009 and assigned application Ser. No. 12/422,725.
BACKGROUND
[0002] A portable icebox, or what is commonly called a "cooler," is
an apparatus that has become commonplace in today's society. A
cooler, generally, is any container operable to prevent, or at
least substantially retard, the transfer of energy into, or out of,
the contents contained within a space defined by its walls. When
one thinks about it, the applications for a container having the
requisite properties to keep its contents at a given temperature,
especially a cold temperature, are seemingly without limit.
[0003] In years past, portable coolers often took the form of a box
with a lid, hinged or otherwise, having walls comprised of tin,
aluminum, or some other metallic material of construction that
could be fashioned around a rigid component having some modicum of
insulating value, such as wood. The result was a somewhat
waterproof shell fastened around an otherwise wooden box such that
ice, water, and any contents having a requirement to be kept cold
could be transported or stored without spoiling.
[0004] While the basic concept, and primary purpose, of a portable
cooler hasn't changed much, the construction and preferred
materials of construction certainly have. With the availability of
Styrofoam (i.e., expanded polystyrene), the waterproofing aspects
and insulating aspects of a cooler can be had with a single
material of construction. Styrofoam is easily molded and
inexpensive to the point that a user doesn't think twice about
discarding the cooler after its use. Of course, the lack of
durability for Styrofoam coolers greatly increases the probability
that a user will, in fact, discard the product after only one or
two uses. Further, presumably due to cost considerations, Styrofoam
coolers usually have separable tops that are not hinged to the main
body of the cooler, thus having a propensity to lose their tops
and, simultaneously, their usefulness. At the inevitable point that
a Styrofoam cooler has outlived its short, useful life, therein
lays the main problem--responsible disposal.
[0005] From a technical standpoint, Styrofoam is recyclable. From
practical and economical standpoints, however, Styrofoam products
cannot be recycled. With current recycling technology, the cost to
recycle Styrofoam products exceeds the value of the reclaimed raw
material. Further, the process of recycling some Styrofoam products
may cause the environmentally detrimental release of CFCs.
Consequently, very few recycling programs, municipal or private,
bother to accept Styrofoam products. As a result, Styrofoam
products, such as Styrofoam coolers, find their way into landfills
after being discarded and such is not desirable as Styrofoam is not
biodegradable. Therefore, what is needed in the art is an
inexpensive portable cooler being comprised of an environmentally
responsible material that is accepted in a majority of community
recycling programs. Further, what is needed in the art is a
portable cooler comprised of a material that is generally known to
biodegrade during prolonged exposure to the elements, should the
cooler not be recycled by its user.
[0006] At the price point of a Styrofoam cooler, but far more
environmentally suitable for disposal, is what amounts to a basic,
single walled box structure made of waxed corrugated cardboard.
Comprising an inexpensive, single use cooler device out of waxed
cardboard is well known in the art. Similarly, a cooler device
comprising a cardboard box with a separable waterproof liner
component is also well known in the art. Promotional companies
seeking to provide a cooler product with customized artwork and
logos for specialized events often make use of printed cardboard
boxes having either a wax treatment, or some other surface
treatment, or separable liner for added resistance to water egress.
The problem with such products, however, is that by the virtue of
their single layer cardboard walls and/or thin separable liner,
they lack durability and are prone to failure when used multiple
times. Also, the insulating capabilities of typical cardboard
coolers are inadequate as the R-factor associated with a given
cooler is limited by the cardboard used in construction. As the
overall thickness and design of the corrugated cardboard used to
construct the box is limited by manufacturing and cost constraints,
coolers made of a single layer of cardboard can only minimally
inhibit the transfer of energy. Therefore, what is needed in the
art is a cooler design that employs cellulose based recyclable
materials of construction, or other recyclable materials of
construction, and offers a means for providing R-values that exceed
that of single walled cardboard based coolers already known in the
art. Further, what is needed in the art is a cooler made of
recyclable, cellulose based materials of construction, or other
recyclable materials of construction, having an overall durability
that makes it suitable for repeated use.
[0007] At the other end of the spectrum from Styrofoam coolers and
basic corrugated boxes are the more expensive, and durable, plastic
coolers with foam based insulating cores. Coolers that fall into
this class are generally purchased for prolonged, repeated use and
are available in a range of sizes and shapes with myriad features.
Consequently, plastic coolers with all the associated features and
designs are predictably expensive. Also, such coolers are not
practical to customize with artwork for special events or
promotions as the hard plastic exteriors are not well suited for
printing. Further, while some types of plastics are accepted by
typical recycling programs, plastic coolers are generally comprised
of plastic types that are not considered economical to recycle.
Moreover, plastic coolers known in the art are not biodegradable
and, even if the components comprising a plastic cooler are
technically, if not practically, recyclable, doing so would require
deconstruction and separation of the components prior to
transferring each to disparate recycling processes. Therefore, what
is needed in the art is a portable cooler comprised of materials
that are not only readily accepted by recycling programs, but are
also easily customizable and printable. Further, what is needed in
the art is a portable cooler having all components comprised of
materials that may be recycled in a single recycling process.
[0008] Prior art for portable coolers are inadequate. They do not
provide for a durable product that can withstand repeated uses,
substantially inhibit energy transfer, be recycled by most
recycling programs, and biodegrade if exposed to the elements for a
prolonged time. The cellulose based recyclable container provides
for these needs in the art, as well as other needs in the art, and
is described in detail herein.
BRIEF SUMMARY
[0009] A cellulose based container that is suitable for providing a
level of thermal insulation is presented. Although exemplary
containers are referred to as ice boxes or coolers throughout this
description, it should be understood that the container may also be
utilized to keep items warm or simply stable. The disclosed
recyclable container is a portable cooler device comprised of
recyclable materials. Some embodiments comprise components
constructed entirely of, or substantially of, cellulose. Other
embodiments may be comprised of recyclable materials not classified
as cellulose such as, but not limited to, cotton, bamboo, hemp, or
other natural fibers.
[0010] Unlike wax treated corrugated boxes already known in the
art, a cellulose based recyclable container is operable to provide
insulating factors that exceed those associated with single layer
construction techniques. By combining an outer shell and inner
shell with a substantially rigid, cellulose based pressed board or
bat sandwiched in between, a cellulose based portable container may
be provided in configurations useful for prolonged maintenance of
the temperature of contents stored within its defined space.
Further, and unlike plastic and foam core portable cooler designs,
a cellulose based portable container may be recycled by most
community based, or private, recycling programs without the need
for deconstruction and separation of its components. Also, a
cellulose based portable container in lieu of being recycled,
whether comprised of cellulose or some other natural fiber, may be
reasonably expected to biodegrade with prolonged exposure to
natural elements in a landfill. Additionally, because embodiments
of a cellulose based portable container are comprised of cardboard
inner and outer shells and, further, are easily constructed via
conversion techniques readily known in the art, shapes and artwork
for various embodiments are easily customizable.
[0011] One embodiment of a cellulose based portable container is
generally comprised of an inner shell having water resistant
properties, an outer shell with a communicable lid, and insulating
boards. Each component of such an embodiment is primarily
constructed from a cellulose based material such as, but not
limited to, corrugated cardboard, recycled newspaper, kraft board,
or the like. As a result, the entire product, although comprising
multiple components, may be recycled in a typical community based
recycling program.
[0012] Each component of the exemplary embodiment may be designed
and converted from "sheet" forms per techniques currently known in
the art. The outer and inner shell components may be cut from a
flat sheet of cardboard, for instance, and creased such that each
may communicate with the other to form a box-like shape with an
integral lid, although it is envisioned that other embodiments may
have a separable lid or a lid that is connected to the main body of
the embodiment by way of a hinging means. Likewise, the insulating
board components may be cut in panels from a larger sheet of
pressed cellulose such that each panel is operable to fit between
the outer surface of the inner shell and the inner surface of the
outer shell when the shells are nested. Notably, the components of
some embodiments of a cellulose based portable container may be
comprised of 100% recycled and/or 100% recyclable materials, but
such is not required of all embodiments of a cellulose based
portable container and, therefore, specific percentages of
recycled, recyclable or reclaimed material should not be construed
to limit the scope of that which is claimed.

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS
[0034] The present disclosure of various embodiments of a
container, as well as features and aspects thereof, is directed
towards providing a portable container operable to substantially
retard the transfer of energy from contents contained within its
defined space, and/or the transfer of energy from outside its
defined space, i.e. a cooler or thermally insulated container, and
being comprised of multiple layers with each layer constructed from
substantially similar materials such that the entire device is
classified as biodegradable or recyclable without a requirement for
deconstruction.
[0035] Generally, a cellulose based recyclable container is a
portable device comprised of recyclable materials. Some embodiments
comprise components constructed entirely of, or substantially of,
cellulose. Other embodiments may be comprised of recyclable
materials not classified as cellulose such as, but not limited to,
cotton, bamboo, hemp, or other natural fibers. Although embodiments
may be used to maintain any temperature level, temperature range or
simply to slow temperature decay or escalation, embodiments will
generally be referred to as a cooler.
[0036] Unlike wax treated corrugated boxes already known in the
art, a cellulose based recyclable container is operable to provide
insulating factors that exceed those associated with single layer
construction techniques, i.e. waxed corrugated boxes for example.
By combining an outer shell and inner shell with substantially
rigid, cellulose based pressed insulating board or bat sandwiched
in between, a cellulose based portable container may be provided in
configurations useful for prolonged maintenance of the temperature
of contents stored within its defined space. Further, and unlike
typical plastic and foam core portable cooler designs, a cellulose
based portable container may be recycled by most recycling
programs, public or private, without the need for deconstruction
and separation of it components. Also, a cellulose based portable
container, in lieu of being recycled, whether comprised of
cellulose or some other natural fiber or material, may be
reasonably expected to biodegrade with prolonged exposure to
natural elements in a landfill. Additionally, because embodiments
of a cellulose based portable container are comprised of cardboard
inner and outer shells and, further, are easily constructed via
conversion techniques readily known in the art, various shapes and
artwork for embodiments are easily customizable by techniques known
in the art.
[0037] One embodiment of a cellulose based portable container is
generally comprised of an inner shell having water resistant
properties, an outer shell with a communicable lid, and insulating
boards, slats or panels. Each component of such an embodiment is
primarily constructed from a cellulose based material such as, but
not limited to, corrugated cardboard, recycled newspaper, kraft
board, or the like. As a result, the entire product, although
comprising multiple components, may be recycled in a typical
community based recycling program.
[0038] Each component of the exemplary embodiment may be designed
and converted from "sheet" forms per techniques currently known in
the art. The outer and inner shell components may be cut from a
flat sheet of cardboard, for instance, and creased such that each
may communicate with the other to form a box-like shape with an
integral lid Likewise, the insulating board components may be cut
in panels from a larger sheet of pressed cellulose such that each
panel is operable to fit between the outer surface of the inner
shell and the inner surface of the outer shell when said shells are
in communication. Alternatively, in lieu of cutting, some
embodiments of a cellulose based portable container may comprise
insulating board components having physical properties that enable
the component to be creased and/or shaped with means similar to the
inner or outer shell components.
[0039] It should be noted that the particular shape of a cellulose
based portable container is limited only by techniques known in the
art and, therefore, while techniques and methodologies for
construction of a cellulose based portable container may be novel
in and of themselves, the particular shape of a cellulose based
portable container or the process used to manufacture a given
embodiment thereof should not limit the scope of the present
invention. As non-limiting examples, the cellulose based portable
container may be square, rectangular, cylindrical, etc.
Additionally, embodiments of the cellulose based portable container
may include multiple compartments or sub-spaces defined within the
overall space of the container such as, but not limited to, an ice
tray like arrangement having multiple pockets operable to receive
contents or a lunch box like arrangement having a dedicated
interior compartment for drink storage.
[0040] Another non-limiting example of an embodiment for a
cellulose based portable container may take a form as described
herein but additionally comprise contents within its defined space
such as, but not limited to, canned liquids, foodstuff, dry ice,
ice, etc. An embodiment comprising such contents may be sealed with
a disposable or biodegradable seal such as, but not limited to, a
starch based plastic. Such an embodiment could be used as a
prepackaged cooler already filled with consumable product and
conveniently ready for use. Still other variations may not require
a sealing component.
[0041] Notably, the components of some embodiments of a cellulose
based portable container may be comprised of 100% recycled and/or
100% recyclable materials, but such is not required of all
embodiments of a cellulose based portable container and, therefore,
specific percentages of recycled, recyclable or reclaimed material
should not be construed to limit the scope of that which is
claimed. Further, while some embodiments of a cellulose based
portable container are primarily constructed of cellulose based
materials, the particular title chosen for the invention should not
be construed as to limit materials that may be used in the
construction of embodiments of the invention. Moreover, it is
anticipated that those skilled in the art may construct a cellulose
based portable container from any naturally occurring fiber or
material with biodegradable properties or recyclable value. A
non-exhaustive list of possible alternative materials of
construction for a cellulose based portable container includes
biodegradable starch based plastics or other non-petroleum based
plastics, polylactic acid, sugar cane fiber (bagasse), wool,
cotton, or hemp.
[0042] As has been described, an advantage of a cellulose based
portable container is that it may be easily recycled by most
recycling programs. Embodiments are comprised of multiple layers of
distinct components that combine to provide superior insulating
properties that exceed other cellulose based products known in the
art. Further, by virtue of using multiple layers, embodiments of a
cellulose based portable container are structurally sound and
operable to withstand repeated use. Moreover, the interior wall of
the inner shell component of a cellulose based portable container
may be water or liquid resistant or even waterproof in some
embodiments and, further, even air-tight or substantially
air-tight. Further, embodiments of a cellulose based portable
container may be compostable, biodegradable, photodegradable,
recyclable, or constructed of recycled content, though all
embodiments may not exhibit all such properties.
[0043] Construction or design of a cellulose based portable
container will be known to those skilled in the art and, therefore,
particular shapes, sizes, or construction techniques associated
with particular embodiments are not factors that may appropriately
limit the scope of the invention. Creasing, folding, and adhesion
techniques are typical in the construction of cellulose based
products and, while possibly novel in and of themselves, are
anticipated techniques for manufacture of a cellulose based
portable container. For example, embodiments of the cellulose based
portable container may be constructed such that the inner and outer
shells are laminated, or otherwise bonded, to the insulating
component. Additionally, embodiments may be designed such that the
components are collapsible and operable to be communicated at the
point of use to create a cellulose based portable container. Still
other collapsible embodiments may be comprised such that the
various components are pre-communicated and a cellulose based
portable container may be configured at the point of use. Moreover,
communication between the multiple components in various
embodiments may be mechanical or chemical in nature as such is
known in the art of cellulose based product manufacture.
[0044] Additional features and aspects that may be included in some
embodiments of a cellulose based portable container include, but
are not limited to, straps, handles, rope features, exterior
treatments, locking mechanisms, separable lids, hinges, tethers,
wheels, drain ports, feet, and viewing portals. The particular
aspect or feature may be novel but the inclusion, or exclusion, of
any such feature is not considered a limiting factor for the
various embodiments.
[0045] Turning now to the figures, where like labels represent like
elements throughout the drawings, various aspects, features and
embodiments will be presented in more detail. The examples as set
forth in the drawings and detailed description are provided by way
of explanation and are not meant as limitations. The various
embodiments thus include any modifications and variations of the
following examples as come within the scope of the appended claims
and their equivalents.
[0046] FIG. 1A is a perspective, front view of one embodiment of a
cellulose based portable container, also referred to as an icebox
100 having an integrally hinged lid and cut out handles. While a
cellulose based portable icebox is not limited to a box-like shape,
the embodiment illustrated in FIG. 1A is comprised of an inner
shell, outer shell, and insulating component that communicate such
that a box-like embodiment is formed. Each panel or wall 110A-F of
the embodiment has an interior surface, which represents a portion
of the inner shell, an exterior surface, which represents a portion
of the outer shell, and an insulating board or panel. In FIG. 1A,
the exterior surface of walls 110A and 110D can be seen while the
interior surface of walls 110B, 110C, 110E, and 110F are shown.
Further, the particular embodiment depicted in FIG. 1A comprises a
cut-out handle 115 such that the portion of the exterior shell
representing walls 110D and 110B (not shown) as well as the
insulating board communicating with the interior surfaces of said
exterior shells are cut so that an operable handle feature is
provided.
[0047] Also featured in the illustrated embodiment of FIG. 1A is a
hinged (not shown) lid aspect. The lid of the embodiment is
represented by panel 110F and is communicable via a creased hinge
to the exterior surface of wall 110C. Unlike walls 110A-E, wall
110F (lid) is constructed such that a lip 120 extends out over an
insulated panel 125. When the lid 110F is in full communication
with the top edges of walls 110A-D, the lip 120 may be in contact
with the top edges of walls 110A-D while the insulated panel 125 is
recessed within the space defined by said walls. Advantageously,
when the lid 110F is in full communication with the top edges of
walls 110A-D, an enclosed, watertight, or water resistant, space is
defined by the inner shell component and exposed surface of the
lid's insulated panel 125.
[0048] FIG. 1B is a perspective, rear view of the same embodiment
of a cellulose based portable icebox 100 having an integrally
hinged lid and cut out handles that is depicted in FIG. 1A. In the
FIG. 1B, however, the exterior surface of walls 110C, 110D and 110F
can be seen while the interior surface of walls 110A and 110B are
shown. Also shown in the FIG. 1B illustration is the hinged 130
feature of the lid 110F. As has been described, the lid 110F in
some embodiments, such as the one depicted herein, may be
constructed such that its outer surface may be a continuation of
the outer shell component and connected via a creased hinge 130
technique known in the art of cardboard box construction. Even so,
it is important to note that the particular hinge 130 feature may
vary with embodiments and, therefore, while possibly novel in and
of itself, should not be construed as a limitation. As a
non-exhaustive list of examples, it is anticipated that the hinge
130 aspect of a cellulose based portable icebox may be comprised of
a strip of fabric, a series of rope loops, a ring, a spiral wound
component, etc.
[0049] FIG. 2 is a perspective, frontal view of the same embodiment
of a cellulose based portable icebox 100 having an integrally
hinged lid and cut out handles that is depicted in FIG. 1A, further
illustrating a cutaway outer shell in order to display a portion of
the interior insulating board. As has been described prior, a
cellulose based portable icebox is generally constructed of an
inner shell nested within an outer shell and having an insulating
board sandwiched between. As can be seen in the FIG. 2
illustration, a portion of the outer shell 210 functioning as the
exterior surface of the front panel 110A is shown cutaway. Residing
beneath the outer shell 210 and outside the inner shell is an
insulating board component 200 comprised of a pressed cellulose. As
has been described, the insulating board for some embodiments is
comprised of a material that may be recycled in conjunction with
the inner and outer shell components without the requirement that
the icebox be deconstructed. For example, in some embodiments, the
inner and outer shell components are constructed of corrugated
cardboard and the insulating board is constructed of a pressed,
recycled cellulose board. Further, while the insulating board
component 200 is shown within panel 110A, it should be understood
that the insulating board component 200 is also within each of the
other walls, floor and lid, that operate to comprise the particular
embodiment depicted.
[0050] Also seen in FIG. 2, is a drain plug feature 215 operable to
be sealed or opened such that liquids contained within the icebox
may be either retained or drained. Drain plug features are well
known in the art of portable iceboxes and, while particular drain
plug designs may be novel in and of themselves, the presence or
absence of a drain plug should not be considered a limiting factor
for a cellulose based portable icebox. Further, it is anticipated
that the materials of construction for a drain plug may be
recyclable along with the other components of the container,
however, such is not necessarily required. Drain plugs and other
features in some embodiments may be of an inconsequential mass such
that the presence of such a feature in a non-recyclable form would
not necessitate the deconstruction of the container prior to
recycling.
[0051] FIGS. 3A and 3B are perspective views of an icebox 300 and
lid 320 that combine to depict another embodiment of a cellulose
based portable container. Notably, FIG. 3A is an example of a lid
320 constructed of a corrugated cardboard, or other suitable
material, that is well known in the art of box making. The lid 320
comprises no insulating board component, as shown, though other
embodiments may comprise an insulating board. The illustration is
offered herein as an example that all embodiments of a cellulose
based portable container may not comprise an insulating board
component within all surfaces that define the embodiment. The
particular lid 320 shown in FIG. 3A is equipped with sides that
extend perpendicularly downward from the edges defined by the lid
320 surface such that it is operable to communicate as a lid for
the icebox depicted in FIG. 3B.
[0052] The icebox depicted in FIG. 3B is substantially constructed
per that which has been outlined relative to previous embodiments.
The particular shape of the icebox shown in FIG. 3B, however, is
tapered in nature and offered herein to illustrate one possible
variation in shape that may be a feature of some embodiments.
Advantageously, the tapered inner 310 and outer 305 walls of the
present embodiment are useful for stacking multiple cellulose based
portable iceboxes in a nested fashion. Other variations in shape
are anticipated as associated construction techniques are well
known in the art and, therefore, while shape variations may serve
novel functions such as reduced space requirements for shipping of
multiple units, the specific shape chosen by those skilled in the
art should not be construed as a limitation.
[0053] FIGS. 4A and 4B are offered as examples of possible
variations in handle aspects that may be employed by various
embodiments of a cellulose based portable container. FIG. 4A is a
close-up view of a cutout handle design 400A as has been reference
for previously described embodiments. Seen in FIG. 4A, the outer
surface 430A of the inner shell component is shown intact.
Advantageously, keeping the inner shell component intact operates
to maintain the integrity of the inner shell's water tightness
aspects. Even so, keeping the inner shell intact is not required in
all embodiments. Also shown in FIG. 4A is the exposed insulating
board component 420A and cut outer shell 410A.
[0054] FIG. 4B is an alternative handle design offered herein as a
non-limiting example of a possible variation for a handle feature
400B that may be comprised in some embodiments. In FIG. 4B, a
rope-like component 420B is shown extending from holes 410B cut
into at least the outer shell of the container. Notably, the holes
may be cut just in the outer shell, or through the outer shell and
insulating board, or all the way through the outer shell and inner
shell. Regardless, fastening techniques for a rope-like handle are
known in the art and may comprise, as a non-limiting example, a
washer type component fastened at each end of the rope handle 420B
such that the rope handle 420B ends cannot pull back through the
holes 410B. Further, as has been described, it is anticipated that
the particular choice of material for the rope may vary with the
embodiment and should not be construed as a limiting factor of
scope. The material may be recyclable by the same processes used to
recycle other components in a given embodiment or, alternatively,
the handle component may comprise so little mass that it would be
considered inconsequential in the recycling process such that
deconstruction of the embodiment would not be required for
recycling.
[0055] Moving now to FIGS. 5 through 8, a typical design and
construction process that is known in the art and may be applied
for the construction of some embodiments of a cellulose based
portable container is described.
[0056] FIG. 5 is a two dimensional view of an exemplary design for
an outer shell 500 included in some embodiments of a cellulose
based portable container that are cube-like in shape, have integral
lids and cut out handle features, illustrating the crease lines
prior to conversion. In some embodiments, the outer shell component
may be converted from a flat sheet of corrugated cardboard or
another suitable material. Depicted in FIG. 5 is an outer shell
component that has been cut from a flat sheet of corrugated
cardboard but has not yet been converted into a finished outer
shell. The crease lines are represented by dotted lines in the
figure and are operable to provide a bending point during the
conversion process. Once converted, panels 505, 510, 510B, 515, 520
and 520T will function as exterior walls for an outer shell
component.
[0057] To convert into an outer shell, the component depicted in
FIG. 5 is folded along the crease lines. Panel 505B is folded to
define a plane perpendicular to panel 505. Next, panel 505 is
folded to define a plane perpendicular to panel 510 which is, in
turn, folded perpendicular to panel 515. Subsequently, panel 515 is
folded perpendicularly to panel 520 thereby providing for the edge
of panel 505 to communicate with the surface of panel 520. Tab 545
can then be folded to communicate with the outer surface of panel
505 and glued in place, as is known in the art. Next, panel 515B
can be folded perpendicular to panel 515 such that it is in plane
with previously folded 505B. Panel 520B is folded to be in a plane
parallel with previously folded panels 505B and 515B and, finally,
to complete the bottom surface of the outer shell of the exemplary
embodiment, panel 510B is folded into a parallel plane
perpendicular to previously folded panels 505B, 515B, and 520B such
that tab 560 may be received and retained by retention feature 550.
Tabs 530, 535 and 540 are folded and glued such that each
communicates with the underside of integrally hinged lid 520T.
Cutout style handles 525 are depicted in panels 505 and 515. Thus,
an outer shell for an exemplary embodiment of a cellulose based
portable container is constructed.
[0058] Once the outer shell has been constructed for the exemplary
embodiment, the inner shell may be converted. Moving now to FIG. 7,
a two dimensional view of an exemplary design for an inner shell
700 included in some embodiments of a cellulose based portable
container is depicted, illustrating the crease lines prior to
conversion. Using substantially the same methodology of conversion
as described relative to the outer shell in FIG. 5, the inner shell
form may be cut from a flat piece of corrugated cardboard, or some
other suitable material, as is known in the art. The crease lines
are operable to provide a folding or bending point. To convert the
inner shell, which in most embodiments will comprise a water
resistant surface, panels 705L, 705R, 705BK and 705F are folded
upward relative to bottom panel 705B such that each occupies a
plane substantially perpendicular to bottom panel 705B. Once each
panel is folded upward, panels 710 may crease to form triangles
extending diagonally outward from the seams defined by the
vertically communicating edges of panels 705L, 705R, 705BK and
705F. The triangles may then be folded behind the outside walls of
adjacent panels and glued, stitched with a cellulose based thread
or otherwise connected, if necessary. Thus, an inner shell for an
exemplary embodiment of a cellulose based portable container is
constructed. Notably, once the exemplary inner shell is folded per
the above outlined steps, extensions 720 and tabs 715 extend from
the top edges of 705L, 705R, 705BK and 705F. Advantageously, as one
of ordinary skill in the art would recognize, the inner shell may
be suitable for container a liquid without leakage, as the seams
formed from the various creases do not provide an open path for a
liquid to escape the volume defined by the inner shell.
[0059] Once the outer shell and inner shell has been constructed
for the exemplary embodiment, insulating panels can be fitted to
the outside walls of the inner shell. Moving back to FIG. 6,
depicted is a two dimensional illustration of an exemplary pattern
for conversion of a pressed cellulose insulating board 600 into
multiple insulating panels operable to be contained within some
embodiments of a cellulose based portable container. As shown, the
front 605F, back 605BK, left and right side 605L-R, bottom 605B and
top 605T insulating board panels may be converted from a flat sheet
of insulating board per techniques known in the art. Each board,
with the exception of the top board 605T and bottom board 605B, is
placed outside the inner shell such that each communicates with the
corresponding outer wall of the inner shell and the tabs 715 of the
inner shell (shown in FIG. 7) are folded over the associated
insulating board and fastened per techniques known in the art.
Notably, when tabs 715 are folded over the installed insulating
boards, extensions 720 extend over the edges of the insulating
boards thereby providing protection to the insulating boards from
exposure. Advantageously, by protecting the insulating boards,
extensions 720 may substantially prevent the insulating boards from
being exposed to liquids that are poured out of the volume defined
by the inner shell of a finished cooler, such as melted ice for
example.
[0060] Once the insulating board panels 605L and 605R (with handle
cutout 610) along with panels 605BK and 605F are in communication
with the inner shell, panel 605B may be placed at the bottom of
previously converted outer shell 500. Next, previously converted
inner shell 700 along with the installed insulating boards may be
nested into the outer shell and secured via techniques known in the
art.
[0061] Moving now to FIG. 8, a two dimensional view of an exemplary
design for a lid insulation wrap 800 included in some embodiments
of a cellulose based portable container is depicted, illustrating
the crease lines prior to conversion. Per the conversion
methodology described prior, the final insulating board 605T may be
communicated with the interior surface 805 of the lid insulation
wrap 800 and secured by folding flaps 810 over the board. The flaps
810 may be fastened via techniques known in the art, such as
gluing. The lid insulation wrap 800 and insulating board 605T
assembly may be fastened to the underside of the integral lid 520T
associated with the outer shell 500, thereby completing the
assembly of an exemplary embodiment of a cellulose based portable
container.
[0062] FIGS. 9A-9B depict the exemplary embodiment 100, shown
closed in FIG. 9A and open in FIG. 9B. As can be seen in FIG. 9B,
the portable container 100 may contain items 905. Advantageously,
the temperature of the items 905 may be maintained or regulated by
virtue of the restricted heat transfer attributable to the portable
container 100. It is envisioned that certain embodiments of a
portable cellulose container 100, may be prepackaged for retail to
include items 905, such as canned beverages. As one of ordinary
skill in the art would recognized, a prepackaged embodiment of a
portable cellulose container 100 may be bought by a consumer,
opened and filled with ice around the items 905.
[0063] FIGS. 10A-10B depict exploded views of the exemplary
embodiment 100. In the FIG. 10 illustrations, he various insulating
boards 201 can be seen positioned relative to corresponding walls
705 of the inner shell. Also, the position of the extensions 720
and tabs 715 of the inner shell component can be seen relative to
the various insulating boards 201.
[0064] FIG. 11 illustrates an exemplary outer shell pattern 1100
that may be folded along the various creases to form an outer shell
component of an exemplary portable container. The method to fold
the exemplary pattern 1100 along the creases is similar to that
which has been described relative to FIG. 5.
[0065] FIG. 12 illustrates an exemplary inner shell pattern 1200
that may be folded along the various creases to form an inner shell
component of an exemplary portable container. The method of folding
the exemplary pattern 1200 along the creases is similar to that
which has been described relative to FIG. 7.
[0066] FIGS. 13A-13B depict an exemplary embodiment 1300 of a
cellulose based portable container configured to contain a wine
bottle or other item of similar size. Advantageously, a cellulose
based portable container such as the exemplary embodiment 1300 will
be suitable for maintaining or regulating the temperature of an
item contained within it. Because the inner and outer shell
components and insulating components may retard the transfer of
thermal energy, the temperature of an item within the container may
be controlled.
[0067] FIG. 14 depicts an exemplary embodiment 1400 of a cellulose
based portable container configured with an insulated chamber 1405
and a non-insulated chamber 1410. Advantageously, for items in need
of temperature regulation such as, for example, a chilled bottle of
white wine, the insulated chamber 1405 may substantially retard
thermal energy transfer to such an extent that the temperature of
the item may be controlled. By contrast, for items that do not
require much if any temperature regulation such as, for example, a
room temperature bottle of red wine, the non-insulated chamber 1410
may serve as a convenient means for containing, protecting and
transporting the item.
[0068] FIG. 15 depicts exemplary embodiments 1500 of a cellulose
based portable container with octagonal outer shell components.
[0069] FIG. 16 illustrates an exemplary outer shell pattern that
may be folded along the various creases to form an outer shell
component of an exemplary portable container according to the FIG.
15 embodiments.
[0070] FIGS. 17A-17B illustrate an exemplary embodiment of a
cellulose based portable container 1700 configured for receipt of a
canned or bottled beverage. Notably, the exemplary embodiment 1700
is depicted without an outer or inner shell component although it
is envisioned that other embodiments may include either or both of
an inner and outer shell component. The exemplary embodiment 1700,
however, is comprised essentially of a single insulating component
1705 formed in the shape of a cylinder with a bottom aspect.
Similar embodiments may be formed in the shape of a tube, without a
bottom aspect. The seam may be formed of stitch, glue, or other
means understood in the art.
[0071] FIGS. 18A-18C depict an exemplary point of sale ("POS")
system 1800 that includes a pair of cellulose based portable
containers 1805A, 1805B. The containers 1805A, 1805B may be
constructed similar to that which has been described above and
include a serious of insulating components sandwiched in a space
defined between the outer walls of an inner shell and the inner
walls of an outer shell. However, it is envisioned that, because
the system 1800 may include exterior system walls such as exterior
side wall 1810S and exterior front wall 1810F, not all embodiments
of containers 1805A, 1805B will necessarily include outer
shells--exterior walls 1810 may suffice to contain the insulating
boards against the inner shells of containers 1805A, 1805B and
serve the functions described above relative to outer shell
components.
[0072] The containers 1805 may include drains 1815 for providing a
point from which liquid held in the containers 1805 can be drained
through a drain system 1820. Notably, as is illustrated in FIG.
18A, the exterior walls 1810 of the system 1800 may be suitable for
display of advertisements, decor or other graphics. A support floor
component 1825 may be included in some embodiments to provide added
support structure and rigidity to the system 1800 for supporting
containers 1805 when loaded with product such as beverages, ice,
etc. It is further envisioned that some embodiments may include
additional support structure 1830 in the lower portion of the
system 1800. The support components of the system 1800, such as but
not limited to floor component 1825 and support structure 1830,
operate to position the containers 1805 at a height above the
ground that may be convenient for presentation of product to a
consumer at a point of sale.
[0073] Although the inner shell and the outer shells of various
portable container embodiments have been described as two separate
components, it will be appreciated that in some embodiments, the
inner shell and outer shell may be formed from a single sheet of
material, that once folded will create an inner and outer shell. In
such an embodiment, the insulating components may be attached or
affixed to the appropriate locations of the sheet prior to being
folded, or at critical junctures in the folding process.
[0074] In other embodiments, rather than using insulating panels,
cellulose based insulation can be sprayed or blown into a space or
cavity defined between the inner shell and the outer shell. Yet in
other embodiments, rather than boards or panels, slats of
insulating material may be used to help maintain the integrity
(such as rigidness) of the container, as well as the shape. The
slats allow the gap between the inner shell and the outer shell to
be separated and thus, air operates as the insulation between the
inner and outer shells. Rather than slats, simple plugs or spacers
may be utilized. In addition, all materials between the inner shell
and the outer shell may be eliminated in some embodiments and
simply air is used as the insulation in the space between the
shells.
[0075] It will also be appreciated that in some embodiments, rather
than having a water tight structure for the inner shell, an insert
or liner may be used to create the water tight structure. For
instance, a structure formed by pressing a cellulose based material
into the appropriate shape may provide the water tight
capabilities, if required. The pressed structure may be constructed
to slide into the interior compartment defined by the inner shell
and either completely wall the interior compartment, only wall the
lower portion of the interior compartment, or simply divide the
interior compartment into two or more chambers.
[0076] In some embodiments, the seams of the outer shell, and
possibly the inner shell, can be perforated to facilitate the
ability to break the container down to a flat form when the
container is retired.
[0077] It will be appreciated that some embodiments may only
include an interior shell with the insulating panels or boards
attached to the outside of the shell. In other embodiments, only an
outer shell may be used with the insulating panels or boards
attached to the interior walls of the outer shell.
[0078] It will also be appreciated that multiple shells may be
utilized to provide even greater thermal characteristics. For
instance, an outer shell, an inner shell and one or more middle
shells may be used in one embodiment. Insulating components can be
included or excluded between the various shells. Advantageously,
this structure can be used to further improve the insulating or
thermal ability of the container.
[0079] It will also be appreciated that the above-presented aspects
and features may also be employed in a bag-type scenario. For
instance, the outer shell and inner shell may be constructed out of
substantially thin material and formed into a multi-layer bag
structure. The insulating material, either as a board or loose form
can then be placed between the layers. When the insulating bag is
not in use, it lays flat or may even be foldable. When in use, the
bag opening can be opened and items placed into the interior of the
insulated bag. Various means can be used to provide a closing
mechanism for the bag opening. Advantageously, such a structure
provides a recyclable insulated bag that can be used for shopping,
grocery transport, fast food transport, etc.
[0080] The various embodiments of a container have been described
using detailed descriptions thereof that are provided by way of
example and are not intended to be limitations. The described
embodiments comprise different features, not all of which are
required in all embodiments. Some embodiments utilize only some of
the features or possible combinations of the features. Variations
of embodiments that are described and embodiments comprising
different combinations of features noted in the described
embodiments will occur to persons of the art.
[0081] It will be appreciated by persons skilled in the art that
the present invention is not limited by what has been particularly
shown and described herein above. Rather the scope of the invention
is defined by the claims that follow.
