The present invention relates generally to shipping systems for storing and/or transporting temperature-sensitive materials and relates more particularly to a novel such shipping system.
It is often desirable to store and/or to transport temperature-sensitive materials, examples of such materials including, but not being limited to, pharmaceuticals, biological samples, foods, and beverages. As a result, various types of shipping systems for storing and/or transporting such materials have been devised, some of these shipping systems being parcel-sized shipping systems and some of these shipping systems being pallet-sized shipping systems. Typically, such parcel-sized shipping systems include an insulated container having a cavity for receiving a temperature-sensitive material. Often, the temperature-sensitive material is housed within a product or payload container, the product or payload container (with the temperature-sensitive material disposed therewithin) being placed in the cavity of the insulated container. Such shipping systems often also include a phase-change material disposed within the insulated container for maintaining the temperature-sensitive material within a desired temperature range. In many instances, such as when the desired temperature range for the temperature-sensitive material is below the ambient temperature outside the insulated container, the phase-change material is refrigerated or frozen prior to being placed in the insulated container so that the phase-change material can act as a coolant.
An example of a parcel-sized shipping system of the type described above is illustrated by U.S. Pat. No. 6,868,982, inventor Gordon, which issued, Mar. 22, 2005, and which is incorporated herein by reference. According to this patent, there is disclosed an insulated shipping container and a method of making the same. In a preferred embodiment, the insulated shipping container comprises an outer box, an insulated insert, an inner box, and a closure member. The outer box, which is preferably made of corrugated fiberboard, comprises a rectangular prismatic cavity bounded by a plurality of rectangular side walls, a closed bottom end, and top closure flaps. The insulated insert is snugly, but removably, disposed within the outer box and is shaped to define a rectangular prismatic cavity bounded by a bottom wall and a plurality of rectangular side walls, the insulated insert having an open top end. The insulated insert is made of a foamed polyurethane body to which on all sides, except its bottom, a thin, flexible, unfoamed polymer bag is integrally bonded. The bag is a unitary structure having a generally uniform rectangular shape, the bag being formed by sealing shut one end of a tubular member with a transverse seam and forming longitudinal creases extending from opposite ends of the seam. The inner box, which is snugly, but removably, disposed within the insert, is preferably made of corrugated fiberboard and is shaped to include a rectangular prismatic cavity bounded by a plurality of rectangular side walls and a closed bottom end, the top end thereof being open. The closure member is a thick piece of foam material snugly, but removably, disposed in the open end of the inner box. In use, a temperature sensitive material is placed in the inner box, together with dry ice or some other temperature-stabilizing material.
Another example of a parcel-sized shipping system of the type described above is illustrated by U.S. Pat. No. 9,045,278, inventors Mustafa et al., which issued Jun. 2, 2015, and which is incorporated herein by reference. According to this patent, there is disclosed an insulated shipping container and method of making the same. In a preferred embodiment, the aforementioned shipping container includes an outer box, an insulated insert, an insulated cover, a payload container and a plurality of coolant members. The insulated insert is snugly, but removably, disposed within the outer box and is shaped to include a plurality of sides and a top. The top includes a raised peripheral edge and a recessed shelf. A large rectangular prismatic cavity surrounded by a plurality of smaller cavities extends downwardly from the recessed shelf. The large cavity of the insulated insert is adapted to receive a payload container. Each of the smaller cavities of the insulated insert is adapted to receive a coolant member, the smaller cavities having a “top hat” shape when viewed from above that includes a crown portion and a brim portion.

System 11 may be used to maintain a payload within a desired temperature range for an extended period of time. Solely for illustrative purposes and not to be limited thereto, system 11 may be configured to maintain a parcel-sized payload within a temperature range of +2° C. to +8° C. for a period of up to 96 hours or longer or, alternatively, may be configured to maintain a parcel-sized payload within a temperature range of +15° C. to +25° C. for a period of up to 96 hours or longer or, alternatively, may be configured to maintain a parcel-sized payload within a temperature range of −15° C. to −25° C. for a period of up to 96 hours or longer.
System 11 may comprise an outer box 13. Outer box 13, which may be, for example, a conventional corrugated cardboard box or carton, may comprise a rectangular prismatic cavity 15 bounded by a plurality of rectangular side walls 17-1 through 17-4, a plurality of bottom closure flaps (not shown), and a plurality of top closure flaps 19-1 through 19-4. Adhesive strips of tape or other closure means (not shown) may be used to retain, in a closed condition, the bottom closure flaps and top closure flaps 19-1 through 19-4.
A tab 21 may be secured, for example, by adhesive or similar means, to an interior face 22 of top closure flap 19-1, and tab 21 may be situated on interior face 22 so as to extend across a free edge 23 of top closure flap 19-1. In this manner, a user may swing open top closure flap 19-1 from a closed state by pulling generally upwardly on tab 21. Tab 21 may be made of a sheet of polymeric material, such as a polyvinyl chloride or similar material. Instead of being secured to closure flap 19-1, tab 21 may be secured to an insulated lid assembly mounted on closure flap 19-1.
A plurality of fasteners 25-1 through 25-4 may be secured, for example, by an adhesive or similar means to interior face 22 of top closure flap 19-1. As will be discussed further below, fasteners 25-1 through 25-4 may be used to removably couple a vacuum insulated panel (VIP) to top closure flap 19-1. In the present embodiment, fasteners 25-1 through 25-4 may be hook (or loop) fasteners, with complementary loop (or hook) fasteners being secured, for example, by adhesive or similar means to the vacuum insulated panel; however, it is to be understood that other types of fasteners, such as adhesive fasteners applied to one or both of the vacuum insulated panel and top closure flap 19-1, may also be used. Also, although four fasteners 25-1 through 25-4 are shown in the present embodiment, it is to be understood that a greater number or lesser number of fasteners 25-1 through 25-4 may be used without departing from the present invention.

System 11 may additionally comprise a board 43, which is also shown separately in
Although not shown in the present embodiment, system 11 may also include a foam pad, which may be made of a polyurethane or the like, positioned between board 43 and the bottom closure flaps of outer box 13. Such a foam pad may serve to keep the components that are contained within outer box 13 from jostling up and down, despite tolerances, and may also provide some shock absorption to protect the contents disposed within outer box 13.
System 11 may further comprise an insulation unit 51. Insulation unit 51, which is also shown separately in
Insulation unit 51 may additionally comprise a support 61, which is also shown separately in
Insulation unit 51 may further comprise a plurality of plastic binding straps 69-1 through 69-3. Straps 69-1 through 69-3, which may be conventional binding straps, may be wrapped around the four sides of support 61 and may be used to help retain vacuum insulated panels 53-1 through 53-5 in an assembled state.
Insulation unit 51 may further comprise a plurality of corner boards 71-1 through 71-4. Corner boards 71-1 through 71-4 may be identical to one another (corner board 71-1 being shown separately in
Insulation unit 51 may be assembled as follows: First, support 61 may be folded and then placed in a fixture (not shown), whereby side portions 65-1 through 65-4 may be maintained in a generally perpendicular orientation relative to central portion 63. Next, panel 53-1 may be positioned with its bottom major surface flush on top of central portion 63. Next, panels 53-2 through 53-5 may be positioned on top of panel 53-1 in a “pinwheel” arrangement. (Preferably, the seams of panels 53-1 through 53-5 face outwardly towards support 61.) Next, corner boards 71-1 through 71-4 may be placed around the exterior four corners of the support 61. Next, straps 69-1 through 69-3 may be wrapped around support 61 and corner boards 71-1 through 71-4. (Preferably, each of straps 69-1 through 69-3 provides a tension of at least 10 psi.) The resulting structure is a five-sided unit defining a cavity bounded by a bottom and four sides and having an open top. As can be appreciated, in the absence of the combination of support 61, straps 69-1 through 69-3, and corner boards 71-1 through 71-4, there is nothing keeping panels 53-1 through 53-5 in an assembled state.

System 11 may further comprise a plurality of foam pads 97-1 through 97-4. Pads 97-1 through 97-4, which may be identical to one another, may be made of an open cell urethane or similar material. Pads 97-1 through 97-4 may be fixedly mounted, for example, with an adhesive (not shown), on the outside surfaces of side walls 87-1 through 87-4, respectively, of liner 81, preferably on upper portion 93 of side walls 87-1 through 87-4. Pads 97-1 through 97-4 may serve to keep liner 81 from moving laterally relative to the remainder of insulation unit 51. In this manner, damage to outer box 13 by flange 96 may be reduced. Pads 97-1 through 97-4 may also provide some nominal thermal insulation.
System 11 may further comprise a product box 99, in which the temperature-sensitive materials (not shown) may be disposed. Product box 99, which may be a conventional corrugated cardboard box, may be appropriately dimensioned to be received within cavity 83 of liner 81. In the present embodiment, product box 99 may be dimensioned to hold a payload volume of approximately 6 L.
System 11 may further comprise a plurality of temperature-control members 101-1 through 101-3. Temperature-control member 101-1 through 101-3, which may be identical to one another, may be appropriately dimensioned to be received, along with product box 99, within cavity 83 of liner 81. Materials suitable for use as temperature-control members 101-1 through 101-3 are exemplified by, but are not limited to, conventional ice packs, conventional gel packs, or refrigerant packs of the type disclosed in U.S. Pat. No. 9,598,622 B2, inventors Formato et al., issued Mar. 21, 2017, and U.S. Patent Application Publication No. US 2018/0093816 A1, inventors Longley et al., published Apr. 5, 2018, both of which are incorporated herein by reference.
According to one embodiment, temperature-control members 101-1 through 101-3 may be in the form of flexible mats having a plurality of discrete sealed pouches, each pouch containing a quantity of a phase-change material (PCM). The phase-change material may be any phase-change material including any water-based or organic phase-change material. For example, if the phase-change material is water-based, the phase-change material may be water, a mixture of water and a thickener (e.g., a polysaccharide thickener) to produce a gelled water mixture, or a water/salt solution with an optional thickener.
Alternatively, if the phase-change material is an organic phase-change material, the phase-change material may be a gelled organic phase-change material, such as is disclosed in U.S. Pat. No. 9,598,622 B2 and U.S. Patent Application Publication No. US 2018/0093816 A1. More specifically, a suitable gelled organic phase-change material may comprise one or more n-alkanes, such as n-tetradecane (C14), n-pentadecane (C15), n-hexadecane (C16), n-heptadecane (C17), n-octadecane (C18), or combinations thereof, together with a gelling agent in the form of a styrene-ethylene-butylene-styrene triblock copolymer and/or a styrene-ethylene-propylene-styrene triblock copolymer. Solely for purposes of illustration, where, for example, system 11 is designed to keep a payload within a temperature range of +2° C. to +8° C., the gelled phase-change material may comprise a mixture of n-tetradecane (C14) and KRATON™ G1654 styrene-ethylene-butylene-styrene (SEBS) tri-block copolymer. Alternatively, where, for example, system 11 is designed to keep a payload within a temperature range of +15° C. to +25° C., the gelled phase-change material may comprise a mixture of n-hexadecane (C16) and KRATON™ G1654 styrene-ethylene-butylene-styrene (SEBS) tri-block copolymer. Each pouch of temperature-control members 101-1 through 101-3 may contain suitable masses of the phase-change material and the gelling agent for the particular application to which system 11 is put. For example, for the particular applications described above, each pouch may contain approximately 150-200 g of the n-alkane(s) and approximately 12-18 g of the gelling agent.
In the present embodiment, there are three temperature-control members 101-1 through 101-3, and each of temperature-control members 101-1 through 101-3 has four generally rectangular, trough-shaped pouches 102; however, it is to be understood that the number of temperature-control members 101-1 through 101-3 and the number and shape of pouches 102 in temperature-control members 101-1 through 101-3 are merely illustrative. Consequently, the number of temperature-control members 101, as well as the number and shape of pouches 102 therein, may be varied while still coming within the scope of the present invention. Moreover, while, in the present embodiment, each pouch 102 of temperature-control members 101-1 through 101-3 contains the same quantity and type of phase-change material, this need not be so as some of temperature-control members 101-1 through 101-3 may contain different phase-change materials than others of temperature-control members 101-1 through 101-3 and/or different pouches of the same temperature-control member may contain different types of phase-change materials.
Temperature-control members 101-1 through 101-3 and product box 99 may be appropriately dimensioned and arranged within liner 81 as follows: First, temperature-control member 101-1 may be arranged within liner 81 so that two of its four pouches are positioned within lower portion 83-1 of cavity 83 and so that two of its four pouches are positioned in upper portion 83-2 of cavity 83 on top of intermediate portion 91 and along side wall 87-3 of liner 81. The two pouches sitting within lower portion 83-1 of cavity 83 may be dimensioned to fit snugly therewithin. Product box 99 may then be positioned on top of the two pouches of temperature-control member 101-1 positioned within lower portion 83-1 of cavity, with the bottom of product box 99 substantially aligned with the bottom of upper portion 83-2 of cavity 83. Temperature-control member 101-2 may then be positioned between liner 81 and product box 99 so that two of its four pouches are positioned on top of intermediate portion 91 of side wall 87-1 and so that two of its four pouches are positioned on top of intermediate portion 91 of side wall 87-4. Temperature-control member 101-3 may then be positioned within liner 81 so that two of its four pouches are positioned on top of intermediate portion of side wall 87-2 and so that two of its four pouches are positioned on top of product box 99. Preferably, liner 81, product box 99, and temperature-control members 101-1 through 101-3 are dimensioned so that temperature-control members 101-1 through 101-3 fit snugly around product box 99 within liner 81. As can be appreciated, the method described above is exemplary; accordingly, the order in which temperature-control members 101-1 through 101-3 are placed around product box 99 and the positioning of temperature-control members 101-1 through 101-3 relative to product box 99 and liner 81 may be varied without departing from the present invention.
System 11 may further comprise a vacuum insulated panel 111. Vacuum insulated panel 111 may be similar in construction to vacuum insulated panels 53-1 through 53-5. A plurality of fasteners (not shown) that may be complementary to fasteners 25-1 through 25-4 may be secured, for example, by adhesive or similar means to vacuum insulated panel 111 and may be arranged on vacuum insulated panel 111 so as to permit detachable mating with fasteners 25-1 through 25-4. In this manner, vacuum insulated panel 111 may be detachably secured to top closure flap 19-1 of outer box 13.
System 11 may further comprise a cover 121. Cover 121, which is also shown separately in
Vacuum insulated panel 111 is preferably positioned on top closure flap 19-1 and cover 121 is preferably positioned on vacuum insulated panel 111 so that liner 81 may be closed simply by the closure of top closure flap 19-1. In this regard, cover 121 and vacuum insulated panel 111 may be collectively regarded as a lid assembly 122 for insulation unit 51.
System 11 may further comprise a temperature indicator 127. Temperature indicator 127, which may be a conventional temperature indicator, may be positionable on top of product box 99 below the top two pouches of temperature-control member 101-3 and may be used to give a real-time indication of whether or not product box 99 is within a desired temperature range. For example, temperature indicator 127 may indicate a positive condition (e.g., by displaying a particular color or symbol) if the temperature is within the desired temperature range and may indicate a negative condition (e.g., by displaying a particular color or symbol) if the temperature is outside of the desired temperature range. Alternatively, temperature indicator 127 may provide a real-time temperature reading. As can readily be appreciated, temperature indicator 127 may be replaced with or may additionally have the capability to measure or to detect shock/movement, global position, moisture/humidity or another environmental parameter.
System 11 minus temperature-control members 101-1 through 101-3 may be referred to herein as a shipper.
One may assemble system 11 as follows: First, outer box 13 may be formed from blank 27, and the bottom closure flaps of outer box 13 may be closed and, preferably, sealed. Next, data logger 41 may be inserted into opening 45 of board 43, and the combination of data logger 41 and board 43 may be placed in the bottom of outer box 13. Next, liner 81 (with pads 97-1 through 97-4 secured thereto) may be placed in insulation unit 51, and the combination of insulation unit 51 and liner 81 may be placed in outer box 13 on top of board 43. Next, cover 121 may be secured to vacuum insulated panel 111, and the combination of cover 121 and vacuum insulated panel 111 may be secured to closure flap 19-1. (Tab 21 may be secured to closure flap 19-1 prior to securement of cover 121 and vacuum insulated panel 111 to closure flap 19-1.)
Next, temperature-control member 101-1 may be placed in liner 81, with two pouches 102 of temperature-control member 101-1 lining the bottom of liner 81 and with two pouches of temperature-control member 101-1 lining one of the side walls of liner 81. Product box 99 (with the temperature-sensitive materials loaded therein and with temperature indicator 127 positioned on top of product box 99) may then be placed in liner 81 on top of the bottom two pouches 102 of temperature-control member 101-1. Temperature-control members 101-2 and 101-3 may then be placed in insert 81 around the remaining exposed faces of product box 99. Next, top closure flaps 19-1 through 19-4 may be closed, the closure of top closure flap 19-1 causing lid assembly 122 to be swung down on top of liner 81 and insulation unit 51.
The product load and temperature-control members 101-1 through 101-3 may be preconditioned at appropriate temperatures prior to being loaded into insert 81 and may be loaded into system 11 at a particular temperature. For example, to maintain the temperature-sensitive materials within a temperature range of +2° C. to +8° C., the product load may be pre-conditioned at +5° C.±3° C., temperature-control members 101-1 through 101-3 may contain a phase-change material having a phase-change temperature of +5° C. and may be pre-conditioned at +3° C.±3° C., and the above-described steps for assembling system 11 may be conducted at +5° C.±3° C. Alternatively, to maintain the temperature-sensitive materials within a temperature range of +15° C. to +25° C., the product load may be pre-conditioned at +20° C.±5° C., temperature-control members 101-1 through 101-3 may contain a phase-change material having a phase-change temperature of +17° C. and may be pre-conditioned at +20° C.±5° C., and the above-described steps for assembling system 11 may be conducted at +20° C.±5° C. Moreover, as discussed above, in other embodiments, it may be desirable to have different pouches of the same temperature-control member or of different temperature-control members contain different types of phase-change materials. For example, according to one embodiment, some of temperature-control members 101-1 through 101-3 may contain a first type of phase-change material, for example, a phase-change material having a phase-change temperature of +17° C., and some of temperature-control members 101-1 through 101-3 may, instead, contain a second type of phase-change material, for example, a phase-change material having a phase-change temperature of +24° C. Alternatively, according to another embodiment, one, some or all of temperature-control members 101-1 through 101-3 may have some pouches 102 (e.g., two of four pouches 102 of a given temperature-control member) containing a first type of phase-change material, for example, a phase-change material having a phase-change temperature of +17° C. and may have some pouches 102 (e.g., the other two of four pouches 102 of the same temperature-control member) containing a second type of phase-change material, for example, a phase-change material having a phase-change temperature of +24° C. Where two different types of phase-change material are each present in two of four pouches 102, the two different types of phase-change material may or may not be present in an alternating sequence of pouches 102 (e.g., A/B/A/B). Furthermore, in certain embodiments, whether the same phase-change materials or different phase-change materials are used, it may be desirable, in certain instances, to precondition all of the temperature-control members at the same preconditioning temperature and, in other instances, to precondition some temperature-control members at a first temperature and to precondition other temperature control-members at a second (i.e., different) temperature. For example, where some temperature-control members contain a first type of phase-change material having a first phase-change temperature and where some temperature-control members contain a second type of phase-change material having a different phase-change temperature, it may be desirable, in certain instances, to precondition the two types of temperature-control members at different preconditioning temperatures.
According to another aspect of the invention, system 11 may be used as follows: First, system 11 may be assembled by a first party in the manner indicated above, except that temperature-control members 101-1 through 101-3 may be omitted from the assembly of system 11. (In addition, product box 99 may be devoid of product.) Then, system 11—minus temperature-control members 101-1 through 101-3—may be shipped from the first party to a second party. Concurrently with the shipping of system 11—minus temperature-control members 101-1 through 101-3 (or therebefore or thereafter), temperature-control members 101-1 through 101-3 may also be shipped from the first party to the second party. Next, the second party may precondition temperature-control members 101-1 through 101-3. Next, while in a temperature-controlled environment, the second party may open system 11, insert the preconditioned temperature-control members 101-1 through 101-3 into insert 81 of system 11, and then re-close system 11. Next, the second party may transport system 11 to a third party, the transport preferably being performed using a refrigerated vehicle. The third party may then use system 11 immediately or may keep it refrigerated until the third party is ready for its use. When ready for its use, the third party may open system 11 and may check temperature indicator 127 to see if the current temperature of product box 99 is in the desired range. If temperature indicator 127 indicates that the current temperature is not within the desired range, system 11 is returned to the second party for reconditioning and no product is shipped therein. If temperature indicator 127 indicates that the current temperature is within the desired range, the third party may remove temperature indicator 127 from system 11 and may pack a product in product box 99. (The removed temperature indicator 127 may then be shipped back to the first party or the second party.) The third party may then ship system 11, minus temperature indicator 127 but with the product, to a fourth party. The fourth party may then remove the product from product box 99 and then return system 11 to the first party for cleaning, refurbishment and reuse.
Alternatively, in another embodiment, the roles of the above-described second and third parties may be performed by a single party, and the role of the fourth party may be eliminated. More specifically, system 11—minus temperature-control members 101-1 through 101-3—may be shipped from a first party to a second party. Concurrently with the shipping of system 11—minus temperature-control members 101-1 through 101-3 (or therebefore or thereafter), temperature-control members 101-1 through 101-3 may also be shipped from the first party to the second party. When the second party wishes to ship a product, the second party may precondition, if needed, temperature-control members 101-1 through 101-3. Next, the second party may load the payload into payload box 99, then may open system 11 and insert temperature-control members 101-1 through 101-3 and payload box 99 into insert 81 of system 11, and then may re-close system 11. Next, the second party may transport the thus-loaded system 11 to a third party. The third party may then remove the product from product box 99 and then return system 11 to the first party or to the second party for cleaning, refurbishment and reuse.
The cleaning and/or refurbishment of system 11 for reuse may comprise the following (or some portion thereof): Removal of temperature-control members 101-1 through 101-3 from liner 81, inspection of temperature-control members 101-1 through 101-3 for damage, and replacement of any damaged temperature-control members 101-1 through 101-3; removal of lid assembly 122 from outer box 13, separation of vacuum insulated panel 111 from cover 121, inspection of cover 121 and vacuum insulated panel 111 for damage, and replacement of any damaged parts; removal of liner 81 and insulation unit 51 from outer box 13, separation of liner 81 from insulation unit 51, inspection of liner 81 and individual components of insulation unit 51 for damage (and checking that tension of straps 69-1 through 69-3 is acceptable), and replacement of any damaged parts; removal of board 43 from outer box 13, inspection of board 43 for damage, and replacement of board 43 if damaged; and replacement of outer box 13. If one or more of liner 81, cover 121, and temperature-control members 101-1 through 101-3 are soiled, but are not otherwise damaged, these items may be cleaned (e.g., wiped with 70% isopropyl alcohol solution) and reused. Such cleaning and reuse of these items may take place even if there is no discernible soiling of these items. Payload box 99 may also be replaced if soiled or damaged.
System 11 possesses a number of advantageous features. One such advantageous feature is that liner 81 may protect vacuum insulated panels 53-1 through 53-5 from becoming soiled, such as by the items that are placed within cavity 83 (e.g., product box 99 and its contents, temperature-control members 101-1 through 101-3) or otherwise. This is particularly the case where liner 81 is made of a liquid impermeable material and does not contain any seams, such as may be the case, for example, where liner 81 is made by thermoforming a single sheet of plastic.
Another advantageous feature of system 11 is that liner 81 may be removably mounted on insulation unit 51. In this manner, after system 11 has been used, liner 81 may be removed from insulation unit 51 and may be cleaned (assuming that liner 81 is made of a material that lends itself to being cleaned) or replaced, with a cleaned or replacement liner 81 then being mounted on insulation unit 51 for a subsequent use. In this manner, problems like cross-contamination, resulting from multiple uses, may be minimized.
Still another advantageous feature of system 11 is that liner 81 may protect vacuum insulated panels 53-1 through 53-5 from damage, such as may occur due to contact with product box 99 and/or temperature-control members 101-1 through 101-3. Relatedly, cover 121 may protect vacuum insulated panel 111 from damage.
Yet another advantageous feature of system 11 is that liner 81 may be sized and shaped relative to product box 99 and to temperature-control members 101-1 through 101-3 so that temperature-control members 101-1 through 101-3 may be snugly and correctly positioned around product box 99, with little available volume for temperature-control members 101-1 through 101-3 to move during shipping. This feature is attributable, at least in part, to the shape of liner 81, whose lower cavity 83-1 is smaller in footprint than its upper cavity 83-2. As a result of this shape, a shelf is formed upon which the side pouches 102 may be seated. This shelf keeps the side pouches 102 aligned with the sides of payload box 99 and prevents some of the side pouches 102 from sliding down relative to the payload box 99 (which could occur with a cavity of uniform cross-sectional area along its height).
Still yet another advantageous feature of system 11 is that lid assembly 122, which includes vacuum insulated panel 111, may be coupled to one of the top flaps of outer box 13. As a result of this integrated construction, the closing of top flap 19-1 of outer box 13 automatically results in the correct placement of vacuum insulated panel 111 on top of liner 81 and insulation unit 15, thereby creating a closed volume for containing product box 99 and temperature-control members 101-1 through 101-3. Moreover, because vacuum insulated panel 111 is detachably secured both to top flap 19-1 and to cover 121, vacuum insulated panel 111 may be periodically inspected (for example, after each use) and replaced if damaged.
Still yet even another advantageous feature of system 11 is that system 11 may include data logger 41 and/or temperature indicator 127. Data logger 41 may be used to provide environmental data, such as ambient temperature, that is encountered by system 11 during its use to transport temperature-sensitive materials. By contrast, temperature indicator 127 may be used to provide an indication to a shipping party as to whether the temperature within product box 99 is at an appropriate temperature at the time of pack-out.
Still a further advantageous feature of system 11 is that system 11 may readily lend itself to being refurbished and/or reused. As noted above, components like liner 81 and cover 121 may be made of cleanable and/or disposable materials. Moreover, the removable mounting of components like liner 81, cover 121, and vacuum insulated panel 111 facilitate the inspection of system 11.
Still yet even a further advantageous feature of system 11 is that system 11 may be adapted for maintaining different payloads at different temperature ranges simply by using different temperature-control members. For example, system 11 may be used, in a first job, to maintain a payload at +2° C. to +8° C. by using a first set of temperature-control members, for example, temperature-control members containing phase-change material having a phase-change temperature of +5° C. and then may be used, in a second or alternative job, to maintain a different payload at +15° C. to +25° C. by using a second set of temperature-control members, for example, temperature-control members containing phase-change material having a phase-change temperature of +17° C. In this manner, a shipping party having an array of different types of temperature-control members may simply select an appropriate type of temperature-control member for a particular job.
Still yet a further advantageous feature of system 11 is that, where temperature-control members 101-1 through 101-3 employ a +5° C. phase-change material of the type described in U.S. Patent Application Publication No. US 2018/0093816, the system can hibernate under refrigeration for up to 5 days without reducing its ability to provide protection for 96 hours.

System 151 may be similar in many respects to system 11. One difference between the two systems may be that, whereas system 11 may comprise temperature-control members 101-1 through 101-3, wherein each of said temperature-control members may have four pouches, system 151 may comprise temperature-control members 153-1 through 153-4, wherein each of said temperature-control member may have two pouches 155. Notwithstanding the above, temperature-control members 153-1 through 153-4 may have a different number of pouches than shown and may include, for example, four pouches.
Another difference between the two systems may be that, whereas system 11 may have the same number of pouches arranged on all six sides of product box 99 (i.e., one pouch), system 151 may have different numbers of pouches on different sides of product box 99. For example, in the present embodiment, three pouches 155, in a stacked configuration, may be positioned over product box 99 (i.e., the two pouches of temperature-control member 153-4 and one of the pouches of temperature-control member 153-3), and one pouch may be positioned over the other five sides of product box 99. The contents of the various pouches 155 of temperature-control members 153-1 through 153-4 may be the same, or some pouches may contain different phase-change materials or may have contents with a different phase-change temperature than the contents of other pouches. Moreover, regardless of the contents of the pouches, the various temperature-control members or even the various pouches of the same temperature-control member may be preconditioned at the same or different temperatures.
According to one embodiment, system 151 may be used to maintain a payload at a temperature of −15° C. to −25° C. for up to 4 days or longer, and each of pouches 155 of temperature-control members 153-1 through 153-4 may contain a salt/water solution having a phase-change temperature of −23° C. An example of a material suitable for use as temperature-control members 153-1 through 153-4 is a 500-ST series KOOLIT® gel pack or saddlebag from Cold Chain Technologies, Inc. (Franklin, MA). In such a case, the product load may be pre-conditioned at −20° C.±5° C., temperature-control members 153-1 through 153-4 may be pre-conditioned at −30° C.±3° C., and system 151 may be assembled at a temperature of +20° C.±3° C.
Also, although not shown, it is to be understood that one or more layers of insulating material may be interposed between product box 99 and an adjacent temperature-control member and/or may be interposed between two adjacent layers of pouches (either of a single, folded temperature-control member or of two discrete temperature-control members) along a common side of product box 99.

System 201 may be similar in many respects to system 11. One difference between the two systems may be that, whereas system 11 may be designed for a payload of approximately 6 L, system 201 may be designed for a payload of approximately 15 L. Accordingly, system 201 may comprise an outer box 203, a board 207, an insulation unit 209, a liner 211, a product box 213, and a lid assembly 215, all of which may be similar in construction to the corresponding components of system 11 but may simply be larger in at least one dimension.
Outer box 201 may comprise a cavity 217 bounded by a plurality of side walls 218-1 through 218-4, a plurality of top closure flaps 219-1 through 219-4, and a plurality of bottom closure flaps (not shown). Board 207 may comprise an opening 221 for snugly receiving an environmental data logger 223, which may be similar to environmental data logger 41 of system 11.

System 201 may further comprise a plurality of temperature-control members 251-1 through 251-5. Temperature-control members 251-1 through 251-5 may be identical to one another and to temperature-control members 101-1 through 101-3, the only difference being that system 201 may include five temperature-control members whereas system 11 may include three temperature-control members. Notwithstanding the above, it is to be understood that the number of temperature-control members 251-1 through 251-5 and the number and shape of pouches 252 in temperature-control members 251-1 through 251-5 are merely illustrative. Consequently, the number of temperature-control members 251, as well as the number and shape of pouches 252 therein, may be varied while still coming within the scope of the present invention. Moreover, while, in the present embodiment, each pouch 252 of temperature-control members 251-1 through 251-5 contains the same quantity and type of phase-change material, this need not be so as some of temperature-control members 251-1 through 251-5 may contain different phase-change materials than others of temperature-control members 251-1 through 251-5 and/or different pouches 252 of the same temperature-control member 251 may contain different phase-change materials. Furthermore, in certain embodiments, whether the same phase-change materials or different phase-change materials are used, it may be desirable to precondition some temperature-control members at a first temperature and to precondition other temperature control-members at a second (i.e., different) temperature.
Temperature-control members 251-1 through 251-5 may be dimensioned relative to product box 213 and liner 211 so that temperature-control member 251-1 may fit snugly in the lower portion of cavity 231, with product box 213 sitting thereon and with temperature-control members 251-2 through 251-5 snugly fitting around the sides and top of product box 213.
System 201 may further comprise a temperature indicator 261, which may be similar in composition and function to temperature indicator 127.
System 201 may be used similarly to system 11.

System 271 may be similar in many respects to system 201. One difference between the two systems may be that, whereas system 201 may comprise temperature-control members 251-1 through 251-5, wherein each of said temperature-control members may have four pouches, system 271 may comprise temperature control members 273-1 through 273-6, wherein each of said temperature-control member may have two pouches 277. Notwithstanding the above, temperature-control members 273-1 through 273-6 may have a different number of pouches than shown and may include, for example, four pouches.
Another difference between the two systems may be that, whereas system 201 may have the same number of layers of pouches arranged on all six sides of product box 213 (i.e., one layer), system 271 may have different numbers of layers of pouches on different sides of product box 213. For example, in the present embodiment, two layers of pouches 277 may be positioned over product box 213 (i.e., the two pouches of temperature-control member 273-2 and one of the pouches of each of temperature-control members 273-3 and 273-4), and one layer may be positioned over the other five sides of product box 213. The contents of the various pouches 277 of temperature-control members 273-1 through 273-6 may be the same, or some pouches may contain different phase-change materials or may have contents with a different phase-change temperature than the contents of other pouches. Moreover, regardless of the contents of the pouches, the various temperature-control members or even the various pouches of the same temperature-control member may be preconditioned at the same or different temperatures.
According to one embodiment, system 271 may be used to maintain a payload at a temperature of −15° C. to −25° C. for up to 4 days or longer, and each of pouches 277 of temperature-control members 273-1 through 273-6 may contain a salt/water solution having a phase-change temperature of −23° C. An example of a material suitable for use as temperature-control members 153-1 through 153-4 is a 500-ST series KOOLIT® gel pack or saddlebag from Cold Chain Technologies, Inc. (Franklin, MA). In such a case, the product load may be pre-conditioned at −20° C.±5° C., temperature-control members 273-1 through 273-6 may be pre-conditioned at −30° C.±3° C., and system 271 may be assembled at a temperature of +20° C.±3° C.
Also, although not shown, it is to be understood that one or more layers of insulating material may be interposed between product box 213 and an adjacent temperature-control member and/or may be interposed between two adjacent layers of pouches (either of a single, folded temperature-control member or of two discrete temperature-control members) along a common side of product box 213.

System 301 may be similar in some respects to system 11. One difference between the two systems may be that, whereas system 11 may be designed for a payload of approximately 6 L, system 301 may be designed for a payload of approximately 59 L. Accordingly, system 301 may comprise an outer box 303, a board 307, an insulation unit 309, and a product box 313, all of which may be similar in construction to the corresponding components of system 11 but may simply be larger in at least one dimension.
Outer box 301 may comprise a cavity 317 bounded by a plurality of side walls 318-1 through 318-4, a plurality of top closure flaps 319-1 through 319-4, and a plurality of bottom closure flaps (not shown). A tab 321, which may be similar in composition and function to tab 21, may be secured to flap 319-4. A plurality of fasteners 325-1 through 325-4, which may be similar in composition and function to fasteners 25-1 through 25-4, may also be secured to flap 319-4. Fasteners 325-1 through 325-4 may be used to detachably mate with complementary fasteners (not shown) secured to a cover or casing 327. Casing 327, which may be made of corrugated cardboard or a similar material, may be used to completely encase a vacuum insulated panel 329. Consequently, vacuum insulated panel 329 may be coupled to and integrated with flap 319-4.
Board 307 may comprise an opening 331 for snugly receiving an environmental data logger 333, which may be similar to environmental data logger 41 of system 11.
Insulation unit 309 may comprise a plurality of vacuum insulated panels 341-1 through 341-5, a support 343, a plurality of corner boards 345-1 through 345-4, and a plurality of straps (not shown), the combination of which may be assembled in a manner analogous to that described above for insulation unit 51.
System 301 may further comprise a protective liner (or shell or insert) 351. Liner 351, which is appropriately dimensioned to be removably mounted on insulation unit 309, may be a rigid structure, either one-piece or multi-piece, comprising or consisting of materials, such as a corrugated cardboard or plastic, polyester paper, expanded polypropylene (EPP), polyethylene terephthalate (PET), plastic corrugate panels, or some combination thereof. Moreover, as will be discussed further below, liner 351 may comprise or consist of a polymer-coated corrugated cardboard, such as a polyurea-coated corrugated cardboard or a polyurethane-coated corrugated cardboard. In the present embodiment, liner 351 may be a one-piece, corrugated cardboard or plastic member shaped to include a cavity 353 bounded by a bottom wall 355 and four side walls 357-1 through 357-4. Each of side walls 357-1 through 357-4 may extend peripherally outwardly at its top end to form a flange 359 and then may extend downwardly a short distance to form an outer wall or extension 361.
Referring now to
Liner 351 is preferably dimensioned so that bottom wall 355 and side walls 357-1 through 357-4 may be inserted into the cavity of insulation unit 309, with bottom wall 355 being positioned over the top of vacuum insulated panel 341-1 and with side walls 357-1 through 357-4 being positioned along the inner faces of vacuum insulated panels 341-2 through 341-5. Flanges 359 may be dimensioned to sit on top of and/or to cover the tops of vacuum insulated panels 341-2 through 341-5, and outer walls 361 may extend downwardly along the exterior faces of support 343. In this manner, liner 351 may cover the exposed inner and top faces of vacuum insulated panels 341-2 through 341-5.
Liner 351 may be maintained in a folded state by insulation unit 309. In other words, if liner 351 is removed from insulation unit 309, there is nothing maintaining side walls 357-1 through 357-4 perpendicular to bottom wall 355. Alternatively, in another embodiment, liner 351 may be maintained in a folded state, independently of insulation unit 309, using one or more strips of adhesive tape (not shown) or using a polymer coating of the type described above (not shown), either of which may be used to secure adjacent side walls 357-1 through 357-4 to one another. Alternatively, in yet another embodiment, liner 351 may be maintained in a folded state, independently of insulation unit 209, by providing blank 370 with suitable mating tabs and slots (not shown). Other ways of maintaining liner 351 in a folded state will be apparent to those of ordinary skill in the art.
Although, in the present embodiment, liner 351 may be a one-piece structure, it is to be understood that liner 351 need not be a one-piece structure and may be formed by the assembly of two or more pieces. For example, liner 351 may be formed by joining together a first structure defining the walls of liner 351 with a second structure defining the flanges and, optionally, outer walls of liner 351. For purposes of illustration, such a first structure defining the walls of liner 351 could be one or more pieces made of corrugated plastic, and such a second structure defining the flanges and, optionally, outer walls of liner 351 could be one or more pieces made of thermoformed plastic.
Also, as noted above, liner 351 may comprise or consist of a polymer-coated corrugated cardboard, such as a polyurea-coated corrugated cardboard or a polyurethane-coated corrugated cardboard. More specifically, for example, blank 370 (
As can readily be appreciated, instead of applying the above-described polymer coating after blank 370 has been folded, the polymer coating could be applied before folding blank 370.
One benefit of applying a polymer coating of the aforementioned type to the corrugated cardboard of liner 351 is that, as a result of such a coating, liner 351 may be rendered more water-resistant or even water-proof. Consequently, liner 351 may become less susceptible to water damage and may be more easily wiped-down or cleaned between uses. In addition, the polymer coating may even make liner 351 more structurally durable, for example, more crush-resistant and/or more scratch-resistant. Where liner 351 comprises or consists of a polymer-coated corrugated cardboard of the type described above (or perhaps even independently thereof), casing 327 may, but need not, similarly comprise or consist of a polymer-coated corrugated cardboard.
System 301 may further comprise a first plurality of spacers 381-1 through 381-4 and a second plurality of spacers 383-1 through 383-4. Spacers 381-1 through 381-4 and spacers 383-1 through 383-4 may function similarly to pads 97-1 through 97-4 of system 11 and may be made of a corrugated cardboard or similar material. Spacers 381-1 through 381-4 may be secured to the outside surfaces of liner 351, and spacers 383-1 through 383-4 may be secured to the outside surfaces of spacers 381-1 through 381-4, respectively.
System 301 may further comprise a plurality of temperature-control members 391-1 through 391-12. Temperature-control members 391-1 through 391-12 may be identical to one another and to temperature-control members 101-1 through 101-3, the only difference being that system 301 may include 12 temperature-control members whereas system 11 may include three temperature-control members. Notwithstanding the above, it is to be understood that the number of temperature-control members 391-1 through 391-12 and the number and shape of pouches 393 in temperature-control members 391-1 through 391-12 are merely illustrative. Consequently, the number of temperature-control members 391, as well as the number and shape of pouches 393 therein, may be varied while still coming within the scope of the present invention. Moreover, while, in the present embodiment, each pouch 393 of temperature-control members 391-1 through 391-12 contains the same quantity and type of phase-change material, this need not be so as some of temperature-control members 391-1 through 391-12 may contain different phase-change materials than others of temperature-control members 391-1 through 391-12 and/or different pouches 393 of the same temperature-control member 391 may contain different phase-change materials. Furthermore, in certain embodiments, whether the same phase-change materials or different phase-change materials are used, it may be desirable to precondition some temperature-control members at a first temperature and to precondition other temperature control-members at a second (i.e., different) temperature.
Temperature-control members 391-1 through 391-12 may be dimensioned relative to product box 313 and liner 351 so that temperature-control member 391-1 through 391-12 may fit snugly around product box 315.
System 301 may further comprise a temperature indicator 395, which may be similar in composition and function to temperature indicator 127.
System 301 may be used similarly to system 11.
Many of the systems described herein may use identical types of temperature-control members to keep payloads within a particular temperature range. For example, the temperature-control members used by systems 11, 201 and 301 to keep a payload within a temperature range of, for example, +2° C. to +8° C., may be identical, the only difference being the number of such temperature-control members used by these systems and the arrangement of such temperature-control members within the respective systems. As a result, a party may keep inventories of various types of temperature-control members designed for keeping payloads within particular temperature ranges and then may use these temperature-control members, as needed, within the various systems. This is advantageous as it reduces the number of different types of temperature-control members that may be needed by a party using differently-sized systems.

System 411 may be similar in many respects to system 11. Accordingly, system 411 may comprise an outer box 413, which may be similar to outer box 13 of system 11, a board 415, which may be similar to board 43 of system 11, an environmental data logger 417, which may be similar to environmental data logger 41 of system 11, an insulation unit 419, which may be similar to insulation unit 51 of system 11, a protective liner 421, which may be similar to protective liner 81 of system 11, a product box 423, which may be similar to product box 99 of system 11 but may be scaled down in size, and a lid assembly 425, which may be similar to lid assembly 122 of system 11. Although not shown in
System 411 may differ from system 11 in that system 411 may additionally comprise a pad 427, which may be made of foam or a similarly suitable material, disposed in outer box 413 under board 415. Pad 427 may be used to keep the components that are contained within outer box 413 from jostling up and down, despite tolerances, and may also provide some shock absorption to protect the contents disposed within outer box 413. Notwithstanding the above, in some embodiments, pad 427 may be omitted.
System 411 may also differ from system 11 in that, whereas system 11 may comprise three temperature-control members 101-1 through 101-3, system 411 may comprise six temperature-control members, namely, three inner temperature-control members 431-1 through 431-3 and three outer temperature-control members 433-1 through 433-3. In the present embodiment, each of inner temperature-control members 431-1 through 431-3 may have four generally rectangular, trough-shaped pouches 432, and each of outer temperature-control members 433-1 through 433-3 may have four generally rectangular, trough-shaped pouches 434. Inner temperature-control members 431-1 through 431-3 may be arranged around product box 423 so that two pouches 432 of inner temperature-control members 431-1 through 431-3 may face each side of product box 423. Outer temperature-control members 433-1 through 433-3 may be similarly arranged around inner temperature-control members 431-1 through 431-3. Preferably, inner temperature-control members 431-1 through 431-3 and outer temperature-control members 433-1 through 433-3 are dimensioned to snugly fit between product box 423 and protective liner 421. Notwithstanding the above, it is to be understood that the number and/or dimensions of inner temperature-control members 431-1 through 431-3 and outer temperature-control members 433-1 through 433-3, as well as the number of pouches 432 and 434 therein, may be varied without departing from the present invention.
Inner temperature-control members 431-1 through 431-3 and outer temperature-control members 433-1 through 433-3 may be similar to temperature-control members 101-1 through 101-3 in terms of size, shape, and general construction. However, as can be appreciated, the types and/or quantities of phase-change materials used in inner temperature-control members 431-1 through 431-3 and in outer temperature-control members 433-1 through 433-3 may or may not be the same as that of temperature-control members 101-1 through 101-3 and may differ therefrom, for example, by one or more of phase-change temperature, specific heat, chemical composition, and quantity. In fact, the types and/or quantities of phase-change material in inner temperature-control members 431-1 through 431-3 and outer temperature-control members 433-1 through 433-3 may be tailored to a particular application. For example, one, some, or all of inner temperature-control members 431-1 through 431-3 and/or one, some, or all of temperature-control members 433-1 through 433-3 may contain a different type and/or a different quantity of phase-change material than is contained in temperature-control members 101-1 through 101-3. (In fact, the type and/or quantity of phase-change material may even differ among different pouches of the same temperature-control member.) Moreover, the preconditioning temperatures used for inner temperature-control members 431-1 through 431-3 and for outer temperature-control members 433-1 through 433-3 may or may not be the same as that for temperature-control members 101-1 through 101-3 and may be tailored to a particular application. For example, one, some, or all of inner temperature-control members 431-1 through 431-3 and/or one, some, or all of temperature-control members 433-1 through 433-3 may be preconditioned at one or more temperatures different than that used to precondition temperature-control members 101-1 through 101-3. Notwithstanding the above, in certain applications, it may be desirable for inner temperature-control members 431-1 through 431-3 and outer temperature-control members 433-1 through 433-3 to contain the same type of phase-change material and/or to be preconditioned at the same temperature. This may be desirable, for example, where the phase-change material that is needed exceeds that which is contained in a single temperature-control member.
Where, for example, system 411 may be used to maintain a payload at a temperature of +15° C. to +25° C. for an extended period of time, such as 4 days or longer, each of pouches 432 of inner temperature-control members 431-1 through 431-3 and each of pouches 434 of outer temperature-control members 433-1 through 433-3 may contain an equal quantity of a phase-change material having a phase-change temperature of +17° C., with inner temperature-control members 431-1 through 431-3 being preconditioned at +20° C. and with outer temperature-control members 433-1 through 433-3 being preconditioned at +5° C. A+17° C. phase-change material suitable for use in pouches 432 of inner temperature-control members 431-1 through 431-3 and in pouches 434 of outer temperature-control members 433-1 through 433-3 may be, for example, a gelled n-hexadecane of the type described in U.S. Pat. No. 9,598,622 B2 and/or U.S. Patent Application Publication No. US 2018/0093816 A1, which are incorporated herein by reference.
Alternatively, pouches 432 of inner temperature-control members 431-1 through 431-3 may contain a +17° C. phase-change material (which may be a gelled n-hexadecane of the type described above), and pouches 434 of outer temperature-control members 433-1 through 433-3 may contain a +24° C. phase-change material (which may be, for example, a gelled n-hexadecane/n-octadecane of the type described in U.S. Pat. No. 9,598,622 B2 and/or U.S. Patent Application Publication No. US 2018/0093816 A1, which are incorporated herein by reference), with inner temperature-control members 431-1 through 431-3 being preconditioned at +20° C. and with outer temperature-control members 433-1 through 433-3 also being preconditioned at +20° C. Alternatively, the contents of inner temperature-control members 431-1 through 431-3 and outer temperature-control members 433-1 through 433-3 may be swapped, with inner temperature-control members 431-1 through 431-3 containing a +24° C. phase-change material preconditioned at 20° C. and with outer temperature-control members 433-1 through 433-3 containing a +17° C. phase-change material preconditioned at 20° C.
Although not shown, to facilitate assembly of system 411, one or more of inner temperature-control members 431-1 through 431-3 and outer temperature-control members 433-1 through 433-3 may be removably or permanently housed in a sleeve or container (e.g., a corrugate sleeve or container). For example, inner temperature-control member 431-1 and outer temperature-control member 433-1 may be housed within a first sleeve or container, inner temperature-control member 431-2 and outer temperature-control member 433-2 may be housed within a second sleeve or container, and inner temperature-control member 431-3 and outer temperature-control member 433-3 may be housed within a third sleeve or container. In particular, where the inner and outer temperature-control members are pre-conditioned at the same temperature, such pre-conditioning may take place with the inner and outer temperature-control members housed within their corresponding sleeve or container. Instead of using a sleeve or container, one or more inner temperature-control members and one or more outer temperature-control members may be coupled to one another by other techniques, such as, but not limited to, shrink-wrapping, hook and loop fasteners, adhesive tape, glue, and the like.
As can readily be appreciated, a protective liner of the type exemplified by protective liners 81, 211 and 421 may be replaced with a protective liner of the type exemplified by protective liner 351 and vice versa. In other words, for example, protective liner 81, protective liner 211, or protective liner 421 could have an overall shape similar to that of protective liner 351 and/or could comprise or consist of the materials used to make protective liner 351, such as a polymer-coated corrugated cardboard, and protective liner 351 could have an overall shape similar to that of protective liners 81, 211 or 421 and/or could comprise or consist of the materials used to make protective liners 81, 211 or 421.

System 511 may be similar in many respects to system 301. Accordingly, system 511 may comprise an outer box 513, which may be similar to outer box 303 of system 301, a board 515, which may be similar to board 307 of system 301, an environmental data logger 517, which may be similar to environmental data logger 333 of system 301, a temperature indicator 521, which may be similar to temperature indicator 395 of system 301, a product box 523, which may be similar to product box 313 of system 301, and temperature-control members 525-1 through 525-12, which may be similar to temperature-control members 391-1 through 391-12, respectively, of system 301.
System 511 may differ from system 301 in that, whereas system 301 may comprise insulation unit 309, system 511 may instead comprise an insulation unit 531. Insulation unit 531, which is also shown in
One benefit of insulation unit 531, particularly where coating 541 at least encapsulates the exposed portions of vacuum insulated panels 533-1 through 533-5, is that system 511 need not include a liner. In other words, product box 523 and temperature-control members 525-1 through 525-12 may be positioned directly within insulation unit 531. This may be beneficial in reducing the cost and complexity of system 511 and may also permit a larger product box to be used.
Although insulation unit 531 is described above as being made by assembling vacuum insulated panels 533-1 through 533-5, support 535, corner boards 537-1 and 537-4, and straps 539-1 through 539-3 and then applying coating 541 to the assembly, one could apply the coating to the individual vacuum insulated panels 533-1 through 533-5 and then assemble the various components.
Also, where vacuum insulated panels 533-1 through 533-5 are assembled with support 535 and then coating 541 is applied to the assembly, it may be possible to omit corner boards 537-1 through 537-4 and/or straps 539-1 through 539-3. In fact, by applying coating 541 directly to an assembly of vacuum insulated panels 533-1 through 533-5, it may further be possible to omit support 535, whereby the resulting insulation unit may consist merely of vacuum insulated panels 533-1 through 533-5 and coating 541, with the vacuum insulated panels 533-1 through 533-5 being held together by coating 541.
System 511 may further comprise a vacuum insulated panel 551 and a casing 553. Casing 553 may be similar to casing 327 of system 301 but may additionally be partially or completely encapsulated within a coating similar to coating 541. Alternatively, casing 553 may be omitted, and vacuum insulated panel 551 may be partially or completely encapsulated within such a coating.
The encapsulation of vacuum insulated panels 533-1 through 533-5 and/or vacuum insulated panel 551 with a coating similar to 541 may result in improved thermal properties for system 511. Also, such encapsulation may create a seal between vacuum insulated panels 533-1 through 533-5 and vacuum insulated panel 551, for example, when outer box 513 is closed.
The embodiments of the present invention described above are intended to be merely exemplary and those skilled in the art shall be able to make numerous variations and modifications to it without departing from the spirit of the present invention. All such variations and modifications are intended to be within the scope of the present invention.
