DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0045] Referring to the figures, a drum and insulative quilt
adapted for insulating a container with temperature sensitive
contents from the surrounding environment is shown.
[0046] The drum quilt 10 can include: a substantially tubular
open-bottom body 12 having an open-bottom 14 including a sidewall
section 16 and a top section 18 having a slit portion 20; the
sidewall 16 includes a predetermined diameter 22 defined as a
distance from one side 24 of the sidewall to an opposite, other
side 26; and a diameter adjusting device 28, whereby the sidewall
diameter 22 is adjustable from a wide diameter position to a narrow
diameter position.
[0047] Some of the major advantages of the drum quilt 10, can
include the following. It substantially improves the maintainance
of a consistant temperature inside the drum quilt, and is less
subject to wide temperature variations, as compared to an
uninsulated drum. This structure provides a secure and tight fit to
a drum 38, for improved insulation. A tight fitting quilt 10, can
provide an insulation air pocket and barrier for minimal
temperature loss or exposure to the outside environment. More
particularly, the quilt 10 provides an inflatable, air barrier
insulation provided by the body 12, substantially enveloping the
drum 38 and contents from the outside environment. The drum quilt
10 is adjustable to fit conventional or unconventional (irregular)
drum or keg sizes. The open-bottom 14 provides for simplified
installation and removal.
[0048] Additionally, the drum quilt 10 is adaptable to being
folded, placed in a package, and can then be express courriered
back to a desired location, after use, such as by UPS. And, the
drum quilt can be made of a durable material which is adapted to
providing some cushioning around the drum during transportation, as
well as insulation of the drum contents (temperature sensative)
from the elements on a loading dock, or on or in a truck, for
example.
[0049] In FIG. 1, a fastening belt is shown for attachment to a
drum truck 60, for improved transportation and maneuvering of
drums.
[0050] In one embodiment as shown in FIG. 2, the diameter adjusting
device 28 includes at least one outwardly facing interconnectable
structure 30 positioned substantially vertically and extending
substantially from the top 18 to the bottom 14 on the sidewall 16.
A flap section 32 attached to the sidewall 16 can have an inner
portion 34 having an inwardly facing interconnectable structure 36,
adjustably, interconnectable with the outwardly facing
interconnectable structure 30. This structure provides a secure and
tight fit to a drum 38, for improved insulation. A tight fitting
quilt 10, can provide an insulation air pocket and barrier for
minimal temperature loss or exposure to the outside
environment.
[0051] More particularly, the quilt 10 provides an inflatable, air
barrier insulation substantially enveloping the drum 38 and
contents from the outside environment.
[0052] As best shown in FIGS. 2 and 3, the drum quilt 10 can
include at least one of the top 18 and the sidewall sections 16
having a substantially clear window 40, adapted to receive a
document viewable through the window 40. This structure
advantageously provides a clear plastic window, to view a bill of
lading on top 18 and when on the sidewall 16, for presenting a
Department of Safety placard, a MSDS sheet or the like.
[0053] Referring to FIG. 6, the top section 18 and sidewall section
16 can be bound by an upper binding 42, and the open-bottom 14 and
sidewall section 16 can be bound by a lower binding 44. This
structure provides an outwardly extending resilliant (springy),
open-bottom structure for easy placement over and removal from a
drum 38. Additionally, this structure provides improved conformance
to the drum 38, because the bindings 42 and 44 tend to extend
outwardly, and the adjustment structure 28 improves a tight envelop
and insulation barrier around the drum 38.
[0054] As best shown in FIG. 7, a substantially vertical sidewall
binding 46 can connect the flap 32 with the sidewall section 16,
which is adapted to provide a durable structure, to securely fit
around a wide diameter or narrower diameter drum structure. By
connecting the structure 36 to one of the outwardly facing
structures 48 and 50, for example, a tight fit is obtainable. In a
preferred embodiment, the structures 30, 36, 48 and 50 include
strips of interconnectable structures, such as Velcro and the like,
for easy adjustment.
[0055] As illustrated in FIGS. 6 and 12-15, the body 12 includes an
interior portion or layer 52, an exterior portion or layer 54 and
an insulative portion or layer 56. Advantageously, each contributes
to the body's durability and resistance to abrasion. A tight
fitting quilt 10 with the desired body 12 construction, can provide
an insulation air pocket and barrier for minimal temperature loss
or exposure to the outside environment. More particularly, a
suitable body 12 construction provides a self-inflatable, air
barrier insulation substantially enveloping the drum 38 and
contents from the outside environment.
[0056] In FIG. 6, the drum quilt 10 has a slit portion 20
preferably positioned on the top 18 adjacent to a portion of the
sidewall 16, adapted to receive a hook portion 58 of a drum truck
60, for facilitating transportation of a drum with temperature
sensative contents. The placement near the sidewall 16, helps to
facilitate connection and removal of the hook 58, from the slit 20
and drum 38. Another feature of the drum quilt 10, is that the slit
20 has an automatic closing at rest feature, or self closing
feature (when not in use), to substantially maintain the desired
insulation and temperature in the drum, as shown in FIG. 4.
[0057] The slit 20 can include a reinforcement layer or area 60,
for improved integrity. More specifically, the slit portion 20 and
reinforcement area 62, include a normally closed condition
(action), to allow manipulation of the drum 38 in use during
transportation, and will spring back closed after removal of the
hook portion 58 of the drum truck 60.
[0058] In FIG. 8, the sidewall section 16 has an open-side portion
64, for simplified placement and removal in certain
applications.
[0059] As shown in FIG. 9, the sidewall section 16 can include one
or more interconnectable structures which are adjustably connected,
for simplified diameter adjustment. This structure can accomadate
one of many different diameters and configurations, ie. two or more
different diameter drums or kegs, for example.
[0060] In a preferred embodiment, the sidewall section 16 includes
at least one substantially adjustable securement device,
substantially as shown in the figures. More particularly, the
securement device can include a plurality of strap and ring
securement devices, substantially as shown in FIG. 9.
[0061] In this embodiment, four equi-spaced securement devices,
identified as items 66, 68, 70, and 72, are shown securely
attached, such as sown directly to the sidewall section 16. This
embodiment provides independant adjustment along various heights,
for improved insulating and enveloping around the drum. Moreover,
the strap and ring securement devices 66, 68, 70, and 72, provide
for: (i) improved securement; (ii) ease of adjustment for a tighter
and a firmer fit to a drum; and (iii) an improved system of
insulating the temperature sensitive material in a keg, drum,
container or the like. Additionally, the drum quilt 10 provides a
self inflating air pocket and barrier, for further insulation
between the temperature sensitive contents and the outside
environment.
[0062] The diameter adjusting devices 66, 68, 70, and 72, include a
number of vertically spaced belts and adjacent loops for individual
adjustment of the diameter of the sidewall section, to accomodate
standard or irregularly configured drums. More specifically, a
first securement device 66 includes a first strap 74 with proximal
and distal interconnectable structures 76 and 78, and adjacent
anchor ring 80. The second securement device 68 includes a second
strap 82 with proximal and distal interconnectable structures 84
and 86, and adjacent second anchor ring 88. The third securement
device 70 includes a third strap 90 with proximal and distal
interconnectable structures 92 and 94, and an adjacent third anchor
ring 96. And finally, the fourth securement device 72 includes a
fourth strap 98 with proximal and distal interconnectable
structures 100 and 102, and adjacent fourth anchor ring 104. The
securement devices are generally sewn or appropriately attached to
the sidewall 16.
[0063] In a preferred embodiment, the securement devices 66, 68, 70
and 72, comprise Velcro, which is a commonly known interconnectable
material. However, other structures can be used, such as but not
limited to snapable belts, zippers, button and hole arrangements,
and the like, as should be appreciated by those skilled in the
art.
[0064] In FIG. 10, a top view of the drum quilt 10 in FIG. 9 is
shown, with a window 40, center seam 106 and slit 20, for
simplified replacement, in the event of damage to the top section
20. Another benefit to the drum quilt 10, is that it is
substantially modular or made with replaceable components, for ease
assembly and/or replacement and repair of component parts, if
needed.
[0065] In FIG. 11, a cross-sectional view of a bottom portion 108.
It can be made of an insulative material for improved insulation.
Also, the bottom portion is adapted to minimize damage to the
bottom of a drum when abruptly set down, for example. The bottom
108 is configured to receive a substantially conventionally shaped
drum in an upperwardly facing receptacle section 110. In one
embodiment, the bottom 108 comprises recycled tires or rubber.
[0066] Referring to FIGS. 12- 15, various body 12 and insulative
quilt constructions are shown. In FIG. 12, a single trip,
substantially recyclable body construction is shown, as detailed
previously, with interior layer 52, exterior layer 54 and
insulative layer 56.
[0067] In a preferred embodiment, the body 10 includes: an interior
layer 52 comprising a coated spun bonded polypropelene, preferably
Typar model 3153 from Reemay; an exterior portion or layer 54 also
comprising the same as above (a coated spun bonded polypropelene,
preferably Typar model 3153 from Reemay); and an insulative portion
56 comprising a polypropelene, polyester, or the like, preferably a
Dupont 808 material, also known as Hollofil. This is believed to be
made of a polypropelene material. This construction provides for
improved consistancy and self-inflatable body structure, after
being crushed and folding during its life. The combination provides
a self-forming and resilient, configuration and structure, which
helps to keep the temperature sensitive material warm, hot or cold,
as desired.
[0068] More specifically, the insulative portion 56 can comprise a
plurality of individual layers of materials, for improved isolation
of the temperature sensitive material from the environment.
[0069] In FIGS. 13 and 15, a multi-trip, (commonly referred to as
therma-grade construction), multi-layer construction 120, body 12
is shown. This therma-grade construction 120 can vary widely. In a
preferred embodiment, the individual layers include a first layer
122, preferably of a vinyl coated polyester or nylon, most
preferably Imperial 600 from Nassimi Corp., in N.Y., N.Y.; second
and fourth layers 122 and 128 of preferably a spun bonded material
such as Typar; a third layer 126 of a holofil or spun bonded
material, most preferably a Dacron Dupont 808 polyester material;
and a fifth layer 130 comprising a coated polyester, such as a
vynal coated nylon, such as Imperial 200 from Nassimi Corp. This
construction provides a durable, self inflatable and resilient
(springy) body 12, for improved placement and removal.
[0070] In FIG. 14 and 15, a seven layer body construction 140, is
shown with layers 142, 144, 146, 148, 150, 152, and 154, from the
exterior to interior layers. In a preferred embodiment, the
individual layers include a first layer (exterior) 142 and seventh
interior layer 154, each comprising a vynal coated polyester,
preferably Imperial 600 (denier) and vynal coated nylon material
preferably Imperial 200, respectively; the second layer 144, fourth
layer 148 and sixth layer 152 can, comprise a spun-bonded or Typar
material; and the third and fifth layers 146 and 150, can comprise
a spun bonded material or holifil, preferably Dacron Dupont 808
polyester holifil, for providing a recycleable drum quilt, which
can contribute to saving fuels and the like, by improved
insulation.
[0071] The multi layer constructions provide improved insulation,
and self inflating constructions which facilitate placement and
removal, because of the resillient nature of the body 12, made with
these constructions. A Nylon interior layer helps to facilitate
placement on a drum, and a Vynal outer layer provides a durable
exterior.
[0072] In one embodiment, pull down means, preferably in the form
of opposite and interior pull-down straps 112 are utilized, as
shown in FIGS. 5 and 8, for facilitating placement over a drum or
keg, for example.
[0073] Thus, the drum quilt 10 is particularly adapted for
insulating a container with temperature sensitive contents from the
surrounding environment. In one application, it includes: a
substantially tubular open-bottom body 12 having an open-bottom 14
including a sidewall section 16 and a top section 18 having a slit
portion 20; the sidewall 16 includes a predetermined diameter
defined as a distance from one side 24 of the sidewall to an
opposite, other side 26; and a diameter adjusting device
(securement device) as shown in the figures, whereby the sidewall
diameter is adjustable from a wide diameter (at rest) position to a
narrow (pulled taunt) position.
[0074] In FIGS. 16-21, a drum quilt in the form of a keg quilt 210,
is shown. It is adapted for insulating a container/keg 238 with
temperature sensitive contents, such as pop or beer from the
surrounding environment . It can comprise: a substantially tubular
open-bottom body 212 having an open-bottom 214 including a sidewall
section 216 and a top section 218 having a slit portion 220; the
sidewall 216 includes a predetermined diameter defined as a
distance from one side 224 of the sidewall to an opposite, other
side 226; and a substantially upwardly extending, upper binding 242
having a port 243 connectable to a resevoir 247 for receiving
liquid.
[0075] In one embodiment, the open-bottom 214 and sidewall section
216 are bound by a lower binding 244. The keg quilt 210 contributes
to minimizing waste by catching spilled liquid. The outer layer can
include a substantially reflective layer to reflect the sunlight
and the like, for improved insulation.
[0076] The difference between the drum quilt in FIG. 1 and the keg
quilt 210, is the placement of the slit 220 in a substantially
middle portion of the top section, and preferably includes first
and second interconnectable sections 221 and 223 to adjustably
close the slit 220, to maximize insulation. Most of the rest of the
keg quilt 210 is substantially similar to the structure of the drum
quilt 10, and thus the item numbers are similar but include two
hundred, for simplicity ( ie. drum quilt 10 and keg quilt 210,
etc.) In FIGS. 12-15 and 22, various embodiments of an insulative
quilt body are shown.
[0077] The insulative quilt body in its simplest form, can
comprise: interior and exterior layers having a coating of at least
one of polypropylene and polyester; an insulative portion
comprising a batt of staple fibers being sandwiched between inside
sides of the interior and exterior layers; and a binding structure
along perimeter edges of the interior and exterior layers securing
the insulative portion therebetween. This construction is a cost
effective improvement to insulate and minimize temperature
fluctuations of temperature sensitive materials.
[0078] In one embodiment, the insulative portion or batt of staple
fibers comprises a layer of at least one of spun bonded material
and Hallofil placed between the interior and exterior layers to
provide a predetermined thickness and density, to provide a desired
insulation. Moreover, the batt of staple fibers herein provides a
self-inflatable construction for improved insulation. It is
believed that the insulative portion or batt of staple fibers
includes a plurality of fibers each with hallow portions that trap
air. Additionally, the batt also has air between each fiber. Thus,
this construction provides at least two individual air pockets or
insulation barriers made of air.
[0079] The exterior layer can include a substantially clear window
adapted to receive a document viewable through the window. The
window could include a shiping destination document, for
example.
[0080] In a preferred embodiment, the interior and exterior layers
comprise a coated, spun bonded material, the coating comprising at
least one of polypropylene and polyester. The coating provides a
substantially air-tight construction, for good self-inflating
properties and improved insulation. In more detail, the interior
and exterior layers comprise at least one layer of Mylar, Nylon and
Vinyl, for a cost effective and suitable air-tight
construction.
[0081] The body includes an interior portion, an exterior portion
and an insulative portion, which comprise durable materials that
can substantially withstand abrasion and severe environments.
Various costructions are possible, depending on the application and
requirements.
[0082] In one body construction, between the insulative portion and
the interior and exterior layers are intermediate layers of a spun
bonded material, defining a five or more layer construction, for
improved durability and resiliance (or a springy construction).
[0083] In one example, the insulative portion comprises one or more
layers of a spun bonded material and one or more layers of a
polyester Hallofil or generic Hallofil material, depending on the
desired density and insulation properties. The term Hallofil is a
term of art and has its ordinary meaning. In a preferred
embodiment, the Hallofil is Dacron Hallofil polyester 808/908 from
DuPont. It should be understood that other Hallofils may be used
depending on the requirements and specifications.
[0084] In a preferred embodiment, an insulative quilt body is
constructed, to substantially enclose a body with a temperature
sensitive material. The body can include: a first and a second cell
each including: interior and exterior layers comprising spun bonded
material each having a coating of at least one of polypropylene and
polyester; an insulative portion comprising a batt of staple fibers
of at least one of a spun bonded material and Hallofil material
being sandwiched between the interior and exterior layers; and a
binding structure comprising a seam along perimeter edges of the
interior and exterior layers securing the insulative portion
therebetween, defining a multi-layer insulative quilt body.
Adventageously, this construction can provide two insulative and
substantially springy, uniform, and resilient constructions. More
specifically, each cell can define a self-inflatable and
substantially springy insulation body.
[0085] In one embodiment, the batt of staple fibers includes a
substantially intimate blend of fibers with a substantially
consistant and uniform density. This contributes in providing a
substantially springy, and more uniform construction. More
particularly, each of the cells is substantially self-inflatable
and provides at least some independant insulation.
[0086] More specifically, there are two preferred processes by
which polyester high loft insulation can be stabilized. The first
is spray bonding. A bonded baft is produced by polyester batting
being sprayed with a resin (glue) and then dried typically in a
three pass oven. On thicker battings, the spray may not fully
penetrate into the middle of the batting, resulting in much of the
resin laying on the exterior surfaces of the batting. This can
create a stiffer, harder to mold batting. The middle fibers, can
become unstabilized prematurely, which means they can loose their
loft and some insulation properties prematurely.
[0087] The second process involves the use of intimate blend of
fibers with different melting temperatures. For example, taking
fibers that melt at low temperatures with regular fibers that do
not melt at such low temperatures a more intimate batt can be
produced. When this batting enters a one pass oven, the low melt
fibers liquify, and flow over the other regular fibers, and when
they leave the oven they cool down and solidify. This process
provides a strong bonding between the two different fibers in the
middle as well as the surfaces. The use of an intimate blend of
fibers can provide a more resilient and better insulative material
than the spray bonded process. In a preferred embodiment, the
intimate blend of fibers include a high quality Dacron Hallofil
polyester Hallofil 808/908,

[0089] which is made as detailed above, and it can be purchased
from DuPont. It is particularly adapted for use in insulative
quilts as detailed herein, which demand a high level of
performance.
[0090] The interior and exterior layers comprise a coating of at
least one layer of Mylar, Nylon, polyester, polypropylene and
Vinyl, for providing a substantially air-tight construction, for
improved insulation.
[0091] In one preferred embodiment, the first and second cells are
substantially independant of each other and define at least a six
layer construction which are simply two cells adhesively or
suitably attached together. In another preferred embodiment, the
first and second cells are substantially independant of each other
and can define at least an eight layer construction. These
constructions are particularly advantageous when used in connection
with, but not limited to, drum quilts, pallet quilts, cargo quilts
and the like.
[0092] Insulated Container
[0093] In its simplest form, an insulated delivery container 500 is
shown in FIGS. 23-28, for insulating temperature sensitive contents
from the surrounding environment. The container 500 can include: a
body 502 including a sidewall section 504, a top section 506 and a
bottom section 508 having at least one of an open-top 510 and
open-sidewall 512; a door 514 pivotably connected to the body 502
for providing an open position for loading and unloading and a
closed position for insulating contents therin, defining an
enclosure; and a temperature control floater 516 for at least one
of sealing temperatures in the enclosure and deviding the enclosure
into at least two compartments, couplable to the body 502.
[0094] The container 500 provides the advantages of being portable,
light weight and easy to carry and made of duarable, washable and
long lasting materials, and is particularly adapted to transport
all hot, chilled or cold or two of the three in the same container.
As should be understood, two or more temperature control floaters
hereafter interchangably referred to as floater or temperature
control floater or device) can be used. In this embodiment, three
tempered items can be stored in the same container 500, with each
enclosure in the container being defined by the dimensions of the
container and each floater. For example, with two floaters three
different tempered items ie. hot, chilled and cold, can be stored
and transported, maintaining the desired temperatures for each
tempered item for hours. The container 500 has many uses, and is
particularly useful in the food, transportation and medical
industries.
[0095] The body 502 in proximity to at least one of the open-top
510 (FIG. 24) and open-sidewall 512 (FIG. 28) includes an outwardly
facing interconnectable structure 518 and the door 514 includes a
flap section 520 attached to at least a portion of an outer
periphery of the door 514 having an inner portion having an
inwardly facing interconnectable structure 522, interconnectable
with the outwardly facing interconnectable structure 518 of the
body 502. This structure defines a closure system. In a preferred
embodiment, upon completion of packing the container 500, the flaps
520 are suitably pulled down completely, to secure the structure
522 of the flaps 520 firmly against the corresponding outwardly
facing interconnectable structure 518, both preferrably Velcro, for
maintaining the desired temperature in the container 500 for a
desired period of time.
[0096] In a preferred embodiment, the inwardly and outwardly facing
interconnectable structures 522 and 518 comprise narrow strips of
Velcro, for simplified opening and closing. Also, at least one of
the inwardly and outwardly facing interconnectable structures 522
and 518 include rigidizers, as shown in FIG. 26, as item 524, to
provide a substantailly flat surface for improved sealing.
[0097] As shown in FIG. 25, the floater is complementarily
configured to be sucurely received in the container 500. In a
preferred embodiment, the floater 516 includes an internal
rigidizer 526, to provide a tight and secure fit within the
container 500.
[0098] As shown in the FIG. 24, peripheral portions of the door,
sidewall and bottom section are bound, as items 528, 530 and 532.
These bindings contribute to providing the desired insulation and
nearly air tight desired construction.
[0099] Referring to FIGS. 25 and 26, the floater 516 is shown
pivotably coupled 534 to the body 502, for ease of adjustment,
loading and unloading. In FIG. 26, the floater 516 is detachably
coupled 536 at one end 538, to the body 502, for certain
applications and ease of cleaning and adjustment. At the other end
of the floater 516 a loop may be included, to facilitate handling
and adjustment of the floater 516.
[0100] As shown in FIG. 25, the body 502 and door 514 include an
interior portion 540, an exterior portion 542 and an insulative
portion 544, for providing the desired insulation and
asthetics.
[0101] The temperature control floater 516 contributes to
minimizing loss of heat or cold depending on the application, and
further helps to maintain a desired temperature for a longer period
of time by seperating the tempered air space form a non-tempered
air space. Thus, the smaller the tempered air space is (where the
temperature sensitive materials are stored in the container 500),
the longer the desired temperature will tend to remain. In
addition, during loading and unloading of temperature sensitive
materials in the container 500, the floater 516 provides a light
weight insulation door that can be easily opened and closed, as
desired, while maintaining and preserving the desired temperature
in a tempered area (where the temperature sensitive materials are
stored) in the container 500. Thus, the user does not have to open
and close the open-top 510 or open-side 512 during loading, for
example.
[0102] The containers shown in FIGS. 23 and 28, can be used to
carry various materials, and are particularly adapted for use in
connection with temperature sensitive materials , chemicals, and
the food and medical industries, for example. The container 500 in
FIG. 28, is adapted for use with flat materials, foods and the
like, such as a lightweight pizza carrier.
[0103] In one embodiment, a light weight carrying tray, preferably
a polymeric coated ( ie. Michem coated) card board with a series of
heat (or cool) exchange ports, is used for improved dense loading
in the container.
[0104] In one embodiment, the floater 516 is a passive element
defining an additional insulation layer, or an active element
providing a heat, chill or cold source. As used herein, passive
element means that the floater is free of a temperature source, and
active element refers to a floater with a compartment, pocket or
the like for helping to provide a desired temperature in proximity
thereto. For example, the floater could include a pocket or
enclosure for holding hot, cold or chill elements or sources, phase
change materials, and the like. For example, when used in the food
industry, cold drinks could be stored in the bottom below the
floater 516 and hot hamburgers and fries above.
[0105] In another embodiment, the interior of the container 500 can
include compartments, pockets and the like, for holding ice,
packages of phase change materials, etc., for providing a desire
temperature in the container. For example, in a preferred
embodiment, one or more packages 554 of phase change materials can
be placed in a pocket 556 in an interior sidewall or floater, for
preserving a desired temperature for a longer period of time, as
shown in FIG. 25.
[0106] As used herein, a phase change material (PCM) refers to
materials that reversably absorb and release heat at a constant
temperature during melting and freezing. PCMs have been used over
the years and can be obtained from Phase Change Laboratories in San
Diego, Calif. PCMs can be obtained for hot and cold medical therapy
and food serving ware, for example. A package of PCMs generally
include water and silica dry powder for cold medical therapy. The
water/silica dry powder is charged (frozen) by placing the package
containing the dry powder in a freezer compartment of a
refrigerator for two to four hours prior to use. The powder remains
soft and conformable even after freezing.
[0107] In more detail, these water/silica powders make use of high
latent heat of fusion and crystallization of water (80
calories/gram) and, therefore can supply cold temperatures at about
zero degrees centigrade for several times as long as liquid water
and gels on the market that use the much lower sensible heat of
water (one calorie/gram/degree centigrade), according to the
literature.
[0108] PCMs can be used as hot or warm supplies as well. For
example, a hot package can be charged by heating for about four
minutes in a conventional microwave oven. Likewise, hot packages of
dry powders also remain conformable above and below use
temperature. As should be understood, these PCM are preferred, and
other similar temperature sources or active temperature elements
are availabe as hot, chill or cold sources, and can be used in
connection with this invention.
[0109] As shown in FIGS. 23 and 24, the body 502 includes
reinforcement sections 546, preferably in the form of straps, at
least partially around the body 502 and handles 548 connected
thereto, to simplify carrying. More particularly, the handles 548
are adjustable carrying straps, which can include an extended
position 550 providing dual shoulder straps and a retracted
position 552 adapted to provide independent handles ( carrying
straps), for carrying heavier loads.
[0110] As detailed herein with respect to the insulative body, the
body 502 can include: interior and exterior layers 540 and 542
having a coating of at least one of polypropylene and polyester; an
insulative portion 544 comprising a batt of staple fibers being
sandwiched between inside sides of the interior and exterior
layers; and a binding structure 528, 530 and 532 along perimeter
edges of the interior and exterior layers 540 and 542 securing the
insulative portion 544 therein. In one embodiment, the batt of
staple fibers comprises a layer of at least one of spun bonded
material and Hallofil. This construction provides a light weight
yet effective insulated container for many applications. In a
preferred embodiment, the interior and exterior layers 540 and 542
comprise a coated, spun bonded material, with the coating being
polypropylene, polyester, blends thereof and the like. For example,
the interior and exterior layers 540 and 542 comprise a layer of
Mylar, Nylon, polyester, Vinyl or the like.
[0111] In certain applications, between the insulative portion 544
and the interior and exterior layers 540 and 542 are intermediate
layers of a spun bonded material, defining at least a five or more
layer construction. This construction can provide a desired
insulation value, while being light weight. For example, the
insulative portion 544 can include one or more layers of a spun
bonded material, one or more layers of a polyester Hallofil
material and the like.
[0112] In a preferred embodiment, the batt of staple fibers
includes a substantially intimate blend of fibers with a
substantially consistant and uniform density, for improved
insulation. Thus, when appropriately constructed, the body 502 and
door 514 include a self-inflatable and substantially springy
insulation layer.
[0113] In a prefered embodiment, the insulative body 502 can
comprise: interior and exterior layers having a coating of at least
one of polypropylene and polyester; an insulative portion
comprising a batt of staple fibers being sandwiched between inside
sides of the interior and exterior layers; and a binding structure
along perimeter edges of the interior and exterior layers securing
the insulative portion therebetween. This construction is a cost
effective improvement to insulate and minimize temperature
fluctuations of temperature sensitive materials.
[0114] In one embodiment, the insulative portion or batt of staple
fibers comprises a layer of at least one of spun bonded material
and Hallofil placed between the interior and exterior layers to
provide a predetermined thickness and density, to provide a desired
insulation. Moreover, the batt of staple fibers herein provides a
self-inflatable construction for improved insulation. It is
believed that the insulative portion or batt of staple fibers
includes a plurality of fibers each with hallow portions that trap
air. Additionally, the batt also has air between each fiber. Thus,
this construction provides at least two individual air pockets or
insulation barriers comprising air.
[0115] The exterior layer can include a substantially clear window
adapted to receive a document viewable through the window. The
window could include a shiping destination document, for
example.
[0116] In a preferred embodiment, the interior and exterior layers
comprise a coated, spun bonded material, the coating comprising at
least one of polypropylene and polyester. The coating provides a
substantially air-tight construction, for good self-inflating
properties and improved insulation. In more detail, the interior
and exterior layers comprise at least one layer of Mylar, Nylon and
Vinyl, for a cost effective and suitable air-tight
construction.
[0117] The body includes an interior portion, an exterior portion
and an insulative portion, which comprise durable materials that
can substantially withstand abrasion and severe environments.
Various costructions are possible, depending on the application and
requirements.
[0118] In one body construction, between the insulative portion and
the interior and exterior layers are intermediate layers of a spun
bonded material, defining a five or more layer construction, for
improved durability and resiliance (or a springy construction).
[0119] In one example, the insulative portion comprises one or more
layers of a spun bonded material and one or more layers of a
polyester Hallofil or generic Hallofil material, depending on the
desired density and insulation properties. The term Hallofil is a
term of art and has its ordinary meaning. In a preferred
embodiment, the Hallofil is Dacron Hallofil polyester 808/908 from
DuPont. It should be understood that other Hallofils and insulative
materials and constructions may be used, depending on the
requirements and specifications.
[0120] In a preferred embodiment, the container 500 includes a
Mylar interior layer 540 and Mylar exterior layer 542 off 600
denier polyester block, and an insulation portion 544. The
insulative portion comprises:
[0121] (i) a first cell comprising a layer of Typar, fiber with a
density of one, one and a half or two ounces, depending on the
required specifications, and another layer of Typar, sown (or
suitably attached) together; and a second cell of the same, each of
the two cells sown ( or suitably attached) together; or
[0122] (ii) one cell comprising two layers of Typar with a fiber
sandwiched therebetween, the fiber having a density of one, one and
a half or two ounces, sewn together at the outer peripheries.

[0136] Courier Expressable Cargo Quilt and Method Therefor
[0137] As shown in FIGS. 29-42, a courier expressable cargo quilt
610 is shown. The quilt 610 comprises: an elongated, substantially
rectangular body 612 comprising an insulative material including a
plurality of panels 614 substantially foldably connected 616,
defining an accordian-like structure 618, the accordian-like
structure 618 having an unfolded position 620 (as shown in FIG. 41)
adapted to facilitate placement of the body 612 substantially over
a temperature sensative load or cargo by unfolding the
accordian-like structure 618 and a folded position 622 (as shown in
FIGS. 5, 7 and 39) adapted to provide a courier-expressable cargo
quilt; and an exterior cover structure 624 adapted to at least
partially enclose the accordian-like structure 618.
[0138] FIG. 36 is an enlarged, partial cross section of the quilt
610, and shows foldable connections 616 including an inside fold
area 626 and an outside fold area 628 having a binding 630 around
the outside fold area 628. In a preferred embodiment, the inside
fold area 626 can be substantially free of any structure, to
provide a thin and narrow profile (accordian-like structure 618),
for simplified carrying and shipping.
[0139] FIG. 35 is a schematic, side cross section of a preferred
embodiment of the quilt 610, with the exterior cover structure 624
having a first cover section 634 and a second cover section 640 of
sufficient dimension to substantially enclose the foldable
connections 616 and to be inter-connectable with each other. This
structure is configured to minimize the over all weight and can be
made of a durable material to withstand shipping and the harsh
environment to which it will be exposed. In more detail, the first
cover section 634 is sufficiently dimensioned to substantially
enclose one side 636 of the foldable connections and a top 638 of
the accordian-like structure 618, and the second cover section 640
sufficiently dimensioned to substantially enclose a second side 642
of the foldable connections, opposite the first cover section
634.
[0140] FIG. 33 is a perspective view of the courier expressable
cargo showing two interconnected cargo quilts 648 and 650, in a
partially open and laid flat condition, the second cargo quilt 650
is opened and laid on top of the first cargo quilt unit, the first
648 and second cargo quilts 650 are inter-connected, and pull rings
are shown clipped to hook rings. More specifically, in a preferred
embodiment, a fastening structure 646 adapted to facilitate
fastening and unfastening (or connecting and unconnecting) the
first courier-expressable cargo quilt 648 with the second
courier-expressable cargo quilt 650. This structure 646 can include
a hook and ring structure, for example.
[0141] In one embodiment, at least one of a body 612 and exterior
cover structure 624 is disconnectably inter-connectable with at
least one of a second body 612 and exterior cover structure 624,
whereby an elongated cargo quilt comprising two courier-expressable
cargo quilts 648 and 650 is provided. As detailed below with
respect to FIGS. 39-42, this structure can easily be positioned
over a load or cargo.
[0142] In one embodiment, the quilt 610 includes at least one
interconnectable strap 654 and ring 656. In more detail, in FIG. 29
the quilt 610 is shown in a portable and closed condition, and in
FIG. 30 in a partially open condition. This structure can simplify
the use of the quilt 610, by providing a simple structure for open
and closing locking and unlocking the quilt 610. The strap 654 can
include a mechanism 658 for inter-connecting to itself, such as a
Velcro inter-connectable structure, for example as shown in FIG.
38.
[0143] In one embodiment, as shown in FIGS. 29 and 30, the quilt
610 can include a plurality of inter-connectable straps and rings
660.
[0144] Also shown in FIGS. 33 and 39-42, further fastening
structure 662 can be utilized for connecting to a hook 664 with a
chord 666, for moving the accordian-like structure 618 to an
unfolded position.
[0145] In FIGS. 39-41 and 43, a method of placing a
courier-expressable cargo quilt at least partially over a load 670
is shown.
[0146] The method 670 can include the steps of: providing 672 an
elongated, substantially rectangular body comprising an insulative
material including a plurality of panals foldably connected,
defining a substantially portable condition and further defining an
accordian-like structure; at least partially opening 674 a cover
structure of the body to expose an anchor structure connected to at
least one of the plurality of panels; and pulling 676 the anchor
structure and unfolding the plurality of panels over a load,
whereby the body is substantially positioned over a load.
[0147] In more detail, the providing step 672 can include providing
at least a first, top substantially rectangular body disconnectably
connected to a second, bottom substantially rectangular body, as
shown in FIG. 33, for covering longer cargos, such as 53 feet, of
temperature sensitive materials, for example.
[0148] In a preferred embodiment, the pulling step 676 includes
pulling an anchor structure of the first, top substantially
rectungular body substantially horizontally and unfolding
substantially most of the panels from the first, top and second,
bottom substantially rectangular bodies over a load, as illustrated
in FIGS. 40 and 41.
[0149] Also in one embodiment, the at least partially opening step
674 includes unlocking a first exterior fastening structure and a
second interior fastening structure, to expose the anchor
structure.
[0150] The pulling (and unfolding) step 676 can further include
providing a chord structure connected to the anchor structure, for
facilitating the unfolding of the plurality of panels over a
load.
[0151] After the unfolding step, the method 670 can further
include: folding the accordian-like structure 618 as shown in FIG.
42, in a folded position; and closing the cover structure, to
provide a courier-expressable cargo quilt, in the following order,
as shown in FIGS. 32, 31, 30 and 29. In more detail, the closing
step can include fastening interior and exterior fastening
structures, as shown in FIGS. 30 and 29, respectively.
[0152] In a preferred embodiment, the providing step can include
providing an insulative material including at least one of a bubble
pack structure and fiberous material, to provide a desired R value.
In a preferred embodiment, the quilt comprises three layers,
specifically Typar, a Dacron Hallofil polyester 808/908 about one
to about two ounce density, and Typar, with Vynal covers and a four
foot long under cover with folding instructions printed on it. As
will be appreciated by those skilled in the art, many other
constructions can be used in the instant cargo quilt, without
departing from the scope of the invention.
[0153] Although various embodiments of the invention have been
shown and described, it should be understood that various
modifications and substitutionns, as well as rearrangements and
combinations of the preceding embodiments, can be made by those
skilled in the art.
