Benefits of technology

The invention is a better insulating container that solves certain problems or provides benefits for the consumer.

Problems solved by technology

The disadvantage of using expanded polystyrene boxes is that they have a limited lifespan due to disintegration of the box during use.
In addition, expanded polystyrene poses an environmental hazard as polystyrene can break down into small pieces which are not appreciably biodegradable.
Additionally, this type of packaging material tends to have poor barrier properties and consequently may be subject to contamination by its contents.
In addition, they typically require a single use plastic liner bag which is environmentally unsustainable.
In addition, the efficiency of use is limited as the boxes have fixed dimensions and can be bulky to transport and store when not in use as they are not collapsible.
Further due to the fixed dimensions their usability is limited for items of non-standard size especially when it is not possible to break items up to fit the container (for food

RE AND HUMIDITY MONITORING USING DIFFERENT TRANSPORT CONTAINERS

[0112]A data logger was placed in with the whole fish inside a 100 micron polyethylene bag and goose neck cable tied closed. This package resided inside a second 100 micron polyethylene bag that contained the cooling gel packs, it was also goose neck cable tied closed (maintaining separation of fish and gel packs). Both fish and gel packs resided inside the thermal lining which was fitted inside the test transport containers (see FIG. 22). The test transport containers included an airfreight approved, corrugated cardboard container, a transport container fabricated from plastic corrugated twin wall sheets (“Fluted PP transport container”) and the thermal insulating transport container of the present invention. The Fluted PP transport container and the thermal insulating container of the present invention were placed inside an airfreight approved, corrugated cardboard container for transport in order to comply with the ap...

THE THERMAL RESISTANCE OF AN EXPANDED POLYSTYRENE BOX AND A THERMAL INSULATING TRANSPORT CONTAINER OF THE PRESENT INVENTION

[0123]An airfreight approved, expanded polystyrene box and the thermal insulating transport container of the present invention were provided with data loggers and sealed. The boxes were placed in an environment having a temperature of 4° C. and when equilibrated were transferred to a second environment having a temperature of 30° C. The temperature of the interior of the empty boxes was monitored over a time period of approximately 90 minutes at one minute intervals. The results are shown in FIG. 14.

[0124]The internal temperature of the polystyrene box reached 25° C. after 30 minutes and 30° C. after approximately 65 minutes. In contrast, the container of the present invention required approximately 43 and 83 minutes respectively to reach the same temperatures.

[0125]This result clearly shows that the container of the present invention has a higher thermal resist...

THE THERMAL RESISTANCE OF DIFFERENT TRANSPORT CONTAINERS

[0126]An airfreight approved, expanded polystyrene box and the thermal insulating transport container of the present invention were provided with data loggers and sealed. Two of the thermal insulating transport containers were provided with a metallised oriented polypropylene film on the outside surfaces of the lid.

[0127]The boxes were placed in an environment having a temperature of 4° C. and when equilibrated were transferred outdoors having an environmental temperature of 33° C. and exposed to sunlight. The temperature of the interior of the empty boxes was monitored over a time period of approximately 90 minutes at one minute intervals. The results are shown in FIG. 15.

[0128]The internal temperature of the polystyrene box reached 25° C. after 20 minutes and exceeded the environmental temperature (33° C.) after approximately 25 minutes. The transport container of the present invention (without metallised oriented polypropyle...

Abstract

A thermal insulating transport container comprising an inner lining, wherein the inner lining is fabricated from a thermal insulation sheet material; and an outer box layer, wherein the outer box layer is fabricated from a water resistant thermal insulation sheet material, wherein a side wall of the outer thermal insulation box layer is connected to an adjacent side wall of the outer thermal insulation box layer by at least one locking tab.

Description

TECHNICAL FIELD[0001]The present invention relates to a thermal insulating transport container. More particularly, the present invention relates to a thermal insulating transport container for transportation of temperature sensitive items, such as seafood, out of cold chain.BACKGROUND ART[0002]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 fibreboard boxes which are packed with a chilling material, such as ice, to keep the items chilled whilst out of the cold chain storage and delivery within the recommended temperature range (which for seafood is usually 2° C. to 8° C.).[0003]The disadvantage of using expanded polystyrene boxes is that they have a limited lifespan due to disintegration of the box during use. In addition, expanded polystyrene poses an environmental hazard as polystyrene can break down into small pieces which are n...
