Description

The present invention relates to insulated shipping containers. More particularly, the present invention relates to an insulated shipping container for transporting temperature sensitive goods such as seafood in an out-of-cold chain.

Known packaging for the storage and transportation of temperature-sensitive items such as seafood includes expanded polystyrene (styrofoam) boxes and polyethylene-coated or wax-impregnated corrugated fiberboard boxes, which are made of cooling materials such as ice. The packaged product is kept cool within the recommended temperature range (usually 2°C to 8°C for seafood) during out-of-cold chain storage and distribution.

The disadvantage of using expanded polystyrene boxes is that they have a limited lifespan due to decomposition of the box during use. In addition, expanded polystyrene poses an environmental hazard because polystyrene can break down into smaller pieces that are not very biodegradable. Furthermore, this type of packaging material tends to have poor barrier properties and, as a result, can be susceptible to contamination by its contents. Additionally, they typically require single-use plastic liner bags that are environmentally unsustainable.

Additionally, boxes have fixed dimensions and are not collapsible, which can make them bulky to transport and store when not in use, thus limiting their efficiency in use. Additionally, the dimensions are fixed, so for non-standard sized items, especially if the item cannot be divided to fit into the container (for foods such as fresh fish, restaurants do not like product separation) Its usefulness is limited.

Many countries around the world have banned polystyrene in the food and grocery sector, including Australia's large seafood trading partners, the United States and Hong Kong. Airlines are reviewing the approval status of Styrofoam air cargo due to a number of product leaks that require planes to be cleaned and inspected.

It would therefore be advantageous to be able to provide an improved insulated container, or at least one that ameliorates the aforementioned problems.

Where a publication of prior art is referred to herein, this reference does not constitute an admission that the publication forms part of the common general knowledge in the art in Australia or any other country. It is clearly understood that

The present invention is directed to an improved insulated container that can at least partially overcome at least one of the aforementioned disadvantages or that can provide useful or commercial advantages to consumers.

In view of the above, the present invention relates to insulated containers for use in housing and transporting temperature sensitive items such as seafood. Temperature-sensitive goods can be delivered "out-of-cold chain" through sustainable means while maintaining product quality. The insulated containers of the present invention provide a reusable and sustainable alternative to polystyrene.

In view of the above, one form of the present invention generally comprises:
an inner lining, the inner lining being manufactured from a thermally insulating sheet material;
an outer box layer, the outer box layer being manufactured from a water-resistant insulating sheet material;
Here, the sidewalls of the outer box layer are in an insulated shipping container connected to adjacent sidewalls of the outer box layer by at least one locking tab.

Insulated shipping containers may be used for any suitable purpose. In embodiments of the invention, insulated shipping containers may be used to transport perishable items. As used throughout this specification, the term "perishable" refers to an article whose potency, freshness, value, safety to the consumer, etc. is temperature sensitive, temperature sensitive, or a combination of the two. That will probably be understood.

For example, perishable items may include meat and meat by-products, fish and seafood, dairy products, fruits and vegetables, flowers, pharmaceuticals, chemicals, organs for transplant, and the like. Preferably, insulated shipping containers can be used to transport temperature sensitive goods. However, in use, insulated shipping containers can be used to transport any form of article where shipping and environmental conditions can adversely affect the article's quality, safety, appearance, shelf life, etc. over time. is assumed.

Insulated shipping containers may be used to transport perishable items by land, air, train, or ship. However, it is understood that the type of transport can vary depending on many factors, such as the goods being transported, whether a refrigerated container is required for the transport, and the destination of the goods. That's probably why.

The insulated shipping container may be of any suitable size, shape or form. Preferably, the size and shape of the insulated shipping container is determined at least in part by the type of perishable item being transported. For example, if a large whole fish (or multiple fish) is being transported, a larger insulated shipping container may be required than if fish fillets are being transported. However, the size, shape and configuration of an insulated shipping container will depend on commercial considerations, the type and destination of transportation, and whether the perishable goods are live, fresh, refrigerated, or frozen. It will be understood that this may vary depending on many factors, such as:

The insulated shipping container includes an inner lining. The inner lining can be manufactured from any suitable type of material that has thermal insulation properties. Preferably, the inner lining may be manufactured from sheet material. Preferably, the inner lining may be manufactured from a flexible sheet material. In embodiments of the invention, the inner lining may be manufactured from a thermally insulating sheet material. Any suitable insulation sheeting material can be used. However, it is envisioned that, in use, the insulation sheeting material can reflect radiant heat, thereby reducing or minimizing the temperature rise to objects at least partially surrounded by the insulation sheeting material. Preferably, the insulation sheet material reflects a significant portion of the radiant heat. In some embodiments of the invention, the insulation sheeting material can reflect at least 50% of radiant heat. More preferably, the insulation sheeting material is capable of reflecting at least 75% of the radiant heat. Most preferably, the insulation sheeting material is capable of reflecting at least 95% of the radiant heat.

Preferably, the insulation layer may be encapsulated between at least one top layer and at least one bottom layer, such that the insulation layer may be substantially encapsulated by at least one top layer and at least one bottom layer. . The thermal barrier layer can be manufactured from any suitable material. For example, the thermal barrier layer may be made from extruded polymers, expanded polymers, foamed polymers, or combinations thereof. Therefore, the thermal insulation layer may be made of polymers (and especially foamed polymers) such as polyethylene, ethylene vinyl acetate, ethylene propylene diene terpolymer, neoprene, nitrile, polyvinyl chloride, silicone, fluoroelastomer, urethane, etc., or any suitable combination thereof. ), but is not limited to these. The insulation layer may be manufactured from closed cell foam insulation material or open cell foam insulation material. In preferred embodiments of the invention, the insulation layer may include a closed cell foam material.

In one embodiment of the invention, the reflective layer may be metallized polyethylene. Although the layers may be disposed in any suitable orientation, it is envisioned that the reflective layer may be disposed in contact with or in close proximity to the outer box layer. Thus, in this embodiment of the invention, the reflective layer forms the outer facing of the inner lining. In another embodiment of the invention, the reflective layer forms the inner facing of the inner lining. In one embodiment of the invention, the insulation sheeting material includes a foam layer encapsulated between two or more layers of reflective material.

Preferably, the insulation sheet material includes at least one layer of antimicrobial material. The antimicrobial layer may be made from any suitable material including, but not limited to, antimicrobial polymers, silver nanoparticle coated polymers, and the like. In one embodiment of the invention, the antimicrobial layer may be antimicrobial polyethylene. Although the layers may be disposed in any suitable orientation, it is envisioned that the antimicrobial layer may be disposed in contact with or near the perishable article. Accordingly, in this embodiment of the invention, the antimicrobial layer forms the inner surface of the inner lining. In an alternative embodiment of the invention, the antimicrobial layer forms the outer surface of the inner lining. In one embodiment of the invention, the insulation sheet material includes a foam layer encapsulated between two or more layers of antimicrobial material. Preferably, the antimicrobial material may be a food grade antimicrobial material.

In one embodiment of the invention, the insulation sheeting material includes a foam layer encapsulated between one or more layers of reflective material and one or more layers of antimicrobial material.

Preferably, the inner lining may be manufactured from a flexible insulating sheet material. The insulation sheet material may be of any suitable thickness. However, it is understood that the thickness of the insulation sheet can vary depending on many factors, such as the requirements of the perishable goods being transported, the environmental ambient temperature, and the degree of flexibility required of the sheet material. Probably.

Preferably, the inner lining can be constructed from food grade approved thermal insulation sheet material. For purposes of this specification, the term "food grade" means an inner lining that is capable of contacting food for human or animal consumption.

In preferred embodiments, the inner lining may be provided with resistance to one or more environmental factors. For example, the inner lining may be water resistant, waterproof, UV resistant, chemical resistant, impact resistant, fire resistant, or a combination thereof. In a preferred embodiment of the invention, the inner lining may be at least water resistant. Preferably, the inner lining may be substantially waterproof, so that when the cooling material melts or the frozen product thaws, the resulting water does not leak out of the inner lining.

Any suitable means of imparting water resistance to the inner lining can be used. For example, the inner lining may be formed from a substantially water-resistant insulating sheet material, may include a water-repellent coating, may include a lining with a high moisture barrier, or the inner lining may at least partially It may be constructed to be water tight or water resistant, or a combination thereof. Preferably, the insulation sheet material can have sealed edges. In this way, the thermal insulation capacity of the material is improved and the water resistance of the sheet material is improved. Any suitable technique for sealing the edges of the sheet material can be used. However, it is understood that sealing techniques can vary depending on many factors such as the type of sheet material to be sealed, the thickness of the sheet material, and the degree of sealing required. That's probably why. For example, the edges of the sheet material may be sealed by using an adhesive or adhesive tape, heat treatment, chemical treatment, mechanical treatment (ultrasonic welding, compression, etc.), or a combination thereof.

In one embodiment of the invention, at least a portion of the periphery of the sheet material may be sealed.

In an alternative embodiment of the invention, the dimensions of the inner lining may be such that substantially all of the inner lining is held in contact with and in close proximity to the inner surface of the outer box layer. The inner dimensions of the outer box layer are substantially the same, as may be the case.

In one embodiment of the invention, the inner lining may be held close to the inner surface of the outer box layer, but may not be attached. It is envisioned that, in use, the air gap formed between the inner lining and the outer box layer may form a thermal barrier between the inner lining and the outer box layer. The inner lining may be held proximate the inner surface of the outer box layer by any suitable means. In embodiments of the invention, a thermally insulating material may be disposed between the inner lining and the outer box layer. In an alternative embodiment of the invention, the inner lining may be at least partially supported by at least one support member attached to the inner surface of the outer box layer, such that the at least one support member Provide separation between the inner surface of the box layer. In a further embodiment of the invention, a cooling material such as ice or a gel pack may be placed between the inner lining and the outer box layer.

In alternative embodiments of the invention, the inner lining can be attached to at least one inner surface of the outer box layer. It is envisioned that, in use, attaching the inner lining to at least one inner surface of the outer box layer can reduce movement of the contents of the insulated shipping container and reduce potential damage. The inner lining may be attached to the inner surface of the outer box layer by any suitable means.

Alternatively, at least one sidewall of the inner lining may be formed by folding a blank or die-cut sheet material along pre-formed lines to create a sleeve.

One or more sheets of material can be used to form the inner lining. In one embodiment of the invention, more than one sheet of material may be used to form the inner lining. The inner lining may have any suitable shape when viewed from above. For example, one or more sidewalls of the container may define a substantially circular, square, rectangular, hexagonal or octagonal void in which perishable items may be placed. In an embodiment of the invention, the side walls of the inner lining may be formed by bending a flexible sheet of material along pre-formed lines and closing the ends longitudinally using aluminum tape. Preferably, the side walls of the inner lining may be formed by bending a flexible sheet of material along pre-formed lines and fastening adjacent side edges together.

Overlapping or abutting side edges of the sheet materials may be fastened together using any suitable technique. However, it is understood that fastening techniques can vary depending on many factors such as the type of sheet material to be sealed, the thickness of the sheet material, and the degree of sealing required.

However, it is understood that sealing techniques can vary depending on many factors such as the type of sheet material to be sealed, the thickness of the sheet material, and the degree of sealing required. That's probably why. For example, the edges of the sheet material may be sealed by using an adhesive or adhesive tape, heat treatment, chemical treatment, mechanical treatment (ultrasonic welding, compression, etc.), or a combination thereof.

In one embodiment of the invention, at least a portion of the periphery of the sheet material may be sealed.

In further embodiments of the invention, the outer box layer and/or lid may be manufactured from a water-resistant insulating sheet material, and the overlapping or abutting side edges of the sheet material may be sealed with adhesive waterproof tape. . In this case, it is believed that sealing using waterproof tape abutting the side edges of the outer box layer and/or the lid can improve the water resistance of the outer box layer and/or the lid. Preferably, the water resistant insulation sheet material can have sealed edges. In this way, the thermal insulation capacity of the material is improved and the water resistance of the sheet material is improved.

The water resistant insulation sheet material may include at least one layer. In embodiments of the invention, the water-resistant insulation sheet material may have a multilayer structure.

In one embodiment of the invention, the outer box layer and/or the lid may be provided with a coating in the form of a UV-resistant film, such as a metallized plastic film. In a preferred embodiment of the invention, the outer box layer and/or the lid may be provided with a metalized polypropylene film. Preferably, the outer box layer and/or the lid may be provided with a metalized stretched polypropylene film. It is envisioned that in use, the metallized plastic film may improve the thermal performance of the outer box layer and/or lid when exposed to sunlight.

The outer box layer and/or lid may be formed by forming the base side and end panels by any method known in the art, such as by folding blank or die cut sheet material along preformed lines. It can be formed by lifting it off the panel. One or more sheets of material may be used. In one embodiment of the invention, a top wall integrally formed as part of the outer box layer blank may be folded to form a lid. In this case, it is envisaged that the top wall may be an extension to one or more side walls of the outer box layer blank. Alternatively, the lid in the form of an open box structure may be formed from a blank. In this case, it is envisaged that the lid may be fitted onto the outer box layer such that the side panels of the lid extend at least partially over the side panels of the outer box layer. In further embodiments of the invention, a sheet of material can be attached to the upper rim of the outer box layer to form a lid or closure.

One or more sidewalls of the outer box layer and/or lid may be attached to adjacent sidewalls by any suitable technique. For example, overlapping or adjacent side edges of sheet materials are fastened using adhesives, adhesive tape, aluminum foil tape, or mechanical fasteners (stitching, staples, etc.), or any suitable combination thereof. Good too. Alternatively, the edge of the sheet material may at least partially attach one or more locking tabs disposed on the edge of the sheet material to one or more tab retention slots disposed on the opposite edge of the sheet material. may be fastened together by inserting the Alternatively, the edges of the sheet material are connected to the first portion of the sheet material such that the one or more folded locking flaps extend at least partially across the edges of adjacent portions of the sheet material. may be fastened together by folding over one or more locking flaps located on the edges of. It is envisioned that, in use, one or more techniques may be used to fasten the edges of the sheet material. In one embodiment of the invention, overlapping or adjacent side edges of the sheet material may be sealed with adhesive waterproof tape. In this case, it is believed that sealing using a waterproof tape abutting the side edges of the inner lining may improve the water resistance of the inner lining.

The outer box layer and/or the lid may be provided with one or more straps. The strap may be of any suitable size, shape, and configuration. However, preferably the straps have sufficient size and mechanical properties (strength, stiffness, shape, etc.) to move and lift the insulated shipping container. It is envisioned that, in use, one or more straps may secure the lid to the outer box layer.

In one embodiment of the invention, the insulated shipping container further includes a cardboard outer container. In an alternative embodiment of the invention, the insulated shipping container further comprises a cardboard sleeve. Any suitable cardboard outer container or cardboard sleeve can be used. In use, it is envisaged that company branding, sender details, recipient details, information regarding perishable goods, etc. can be printed on the outer cardboard container or on the cardboard sleeve. In this way, the insulated shipping container may be reused by different companies.

The insulated shipping container may be provided with one or more monitoring devices. The monitoring device may be of any suitable type and may monitor any suitable parameter associated with the insulated shipping container. However, preferably one or more monitoring devices provide information regarding the condition of the inner lining and/or the outer box layer and/or the lid. For example, a suitable monitoring device may be an electronic monitoring device. Electronic monitoring devices can include electronic chips, Internet of Things (IoT) modules, data loggers, radio frequency identification (RFID) chips, near field communication (NFC) tags, smart tags, and the like. In use, the monitoring device tracks and/or traces the insulated shipping container or its individual components, identifies worn or damaged components, and monitors temperature or humidity at one or more locations within the insulated shipping container. It is envisaged that a combination thereof may be used. In one embodiment of the invention, one or more of the inner lining, outer box layer, and lid may be provided with one or more monitoring devices.

For example, tracking and verification of reusability and recyclability of insulated shipping containers may be accomplished by embedding electronic chips (IoT) at the point of manufacture inside each of the individual components of the container. Each layer may be scanned at the point of manufacture via an electronic chip reader (and may also be scanned at one or more other points in the product lifecycle, such as by the sender, transporter, receiver, recycler, etc.). (often), data from each embedded electronic chip may be sent to a recipient such as the cloud and API of a blockchain platform. Therefore, data may be written to the blockchain. Advantageously, this allows the location of an insulated shipping container to be tracked throughout its lifecycle (eg, from first use to recycling). It is envisaged that this may provide complete verification of reuse and recyclability. Additionally, this information may be used to aid in inventory replenishment.

One or more monitoring devices may be placed on any suitable portion of the inner lining, outer box layer, and lid. However, the location of the monitoring device may vary depending on many factors, such as the functionality of the monitoring device and the transmission frequency (both in terms of the frequency of time that the monitoring device transmits and/or the radio frequency that the monitoring device transmits). That will probably be understood. In one embodiment of the invention, the monitoring device may be placed on the surface of the inner lining and/or the outer box layer and/or the lid. In this case, the monitoring device may be at least partially covered by a polymeric film in order to provide the monitoring device with a protective barrier and to fix the monitoring device to the inner lining and/or the outer box layer and/or the lid. It is assumed that In one embodiment of the invention, the monitoring device may be placed within the structure of the inner lining and/or outer box layer and/or lid.

The inventors have found that the combination of an inner lining, water-resistant outer box layer, and lid as described above provides an alternative to polystyrene as an "out-of-cold chain" shipping container.

For example, the present invention provides improved insulation that provides an effective shipping container suitable for "out-of-cold chain" product transportation. In addition, the present invention improves flexibility in use through customizable construction and folding (flat pack) ability for convenient "cost-effective transportation" and convenient storage when not in use. . The present invention also improves cost efficiency and sustainability through the ability to reuse and recycle materials without destroying them.

FIG. 22 shows an insulated shipping container according to an embodiment of the invention used in shipping tests (see Example 1). An inner lining (301) made of a reflective layer and comprising an inner surface sealed with aluminum tape (307) packages the fish fillets (28) inside the plastic bag.

23-25 illustrate a shipping container manufactured from an approved air cargo corrugated container (FIG. 23), a plastic corrugated twin-wall sheet (FIG. 24), and a container of the present invention, as described in Example 1. 25 shows temperature and humidity changes over 1.2 days during a shipping test for an insulated shipping container (FIG. 25) according to an embodiment; FIG. Surprisingly, the insulated shipping container of the present invention is more effective at maintaining stable humidity and temperature than current air cargo approved packaging options.

Example 1: Temperature and Humidity Monitoring Using Different Shipping Containers A data logger is placed with the whole fish in a 100 micron polyethylene bag and the gooseneck cave is tied and closed. This package resides in a second 100 micron polyethylene bag containing the chilled gel pack, which is also closed by tying the gooseneck cave (maintaining separation of the fish and gel pack). Both the fish and gel pack are inside a thermal lining attached to the inside of the test shipping container (see Figure 22). Test shipping containers include air cargo approved corrugated containers, shipping containers made from plastic corrugated twin wall sheets ("Fluted PP shipping containers"), and insulated shipping containers of the present invention. The grooved PP shipping containers and insulated containers of the present invention are placed within air cargo approved corrugated containers for shipping to comply with appropriate regulations.

Humidity and temperature inside each box was monitored every 15 minutes over a period of 1.2 days.

The results for an air cargo approved cardboard container can be seen in Figure 23.

Humidity and temperature within the cardboard container varied considerably. Temperatures varied between 18.6°C and 2.5°C with an average of 6.9°C, representing three "out-of-cold chain" transport situations over different periods of time. Temperature and humidity stabilized only after re-entering the cold chain at approximately 20:53.

This means that air cargo approved corrugated containers are not efficient at maintaining the temperature and humidity required to ensure product quality and are therefore unsuitable as stand-alone "out-of-cold chain" shipping containers. It clearly shows that it is not.

The results for the grooved PP shipping container can be seen in Figure 24.

The insulation quality of the grooved PP shipping container decreased somewhat, but both humidity and temperature changed. Temperatures varied between 15.9°C and 3.2°C with an average of 3.6°C. Humidity varied from 85.2% to 68.9% with an average of 82.1%. The temperature and humidity stabilized only after re-entering the cold chain at approximately 20:53.

This means that shipping containers manufactured from plastic corrugated twin-wall sheets are not efficient at maintaining the temperature and humidity necessary to ensure product quality, and therefore separate "out-of-cold chain" shipping containers It clearly shows that it is not suitable for this purpose.

The results for an insulated shipping container of the present invention can be seen in FIG.

Both humidity and temperature were relatively constant and varied only during operation and deployment during shipment. Temperatures varied between 15.1°C and -0.6°C with an average of 0.2°C. However, once it stabilizes at approximately 06:08, the fluctuations are negligible. Humidity varied between 93.1% and 68.2% with an average of 90.6%. However, once it stabilizes at approximately 06:08, the fluctuations are negligible.

This shows that the insulated shipping container of the present invention is efficient in maintaining the necessary temperature and humidity to ensure product quality.

Example 2: Measurement of Thermal Resistance of Expanded Polystyrene Boxes and Insulated Shipping Containers of the Invention The air cargo approved expanded polystyrene boxes and insulated shipping containers of the invention are equipped with a data logger and sealed. The box was placed in an environment at a temperature of 4°C and when equilibrated was transferred to a second environment at a temperature of 30°C. The temperature inside the empty box was monitored at 1 minute intervals over a time period of approximately 90 minutes. The results are shown in FIG.

The temperature inside the polystyrene box reached 25°C after 30 minutes and 30°C after about 65 minutes. In contrast, containers of the present invention required approximately 43 and 83 minutes, respectively, to reach the same temperature.

This result clearly shows that the container of the present invention has higher heat resistance than the expanded polystyrene box.

Example 3: Measurement of thermal resistance of different shipping containers The air cargo approved expanded polystyrene boxes and insulated shipping containers of the present invention are equipped with a data logger and sealed. Two of the insulated shipping containers are equipped with metalized stretched polypropylene film on the outer surface of the lid.

The box was placed in an environment with a temperature of 4°C and, when equilibrated, was moved outdoors with an ambient temperature of 33°C and exposed to sunlight. The temperature inside the empty box was monitored at 1 minute intervals over a time period of approximately 90 minutes. The results are shown in FIG.

The temperature inside the polystyrene box reached 25°C after 20 minutes and exceeded the ambient temperature (33°C) after about 25 minutes. Shipping containers of the present invention (without metallized stretched polypropylene film) required approximately 30 and 40 minutes, respectively, to reach the same temperature. Shipping containers of the present invention (with metallized stretched polypropylene film) required approximately 30 and 50 minutes, respectively, to reach the same temperature.

This result clearly shows that the containers of the invention have higher heat resistance than polystyrene. The results also show that providing the shipping container of the present invention with an additional reflective layer on the outside of the lid improves the thermal performance of the shipping container when exposed to sunlight.
