Product transport containers
Product transport containers are disclosed. Such containers can provide one or more advantages compared to existing containers. For example, product transport containers described herein can maintain a product at a desired temperature for an extended period of time, including without the use of an active heating or cooling component. Such product transport containers described herein may also provide improved breathability, thermal insulation, and/or mechanical strength or dimensional stability. Such containers can include a plurality of walls defining an interior volume and a selectively openable side permitting movement of the product into and out of the interior volume of the container. The walls can be formed from a thermoformed non-woven fabric.
1. A product transport container comprising:
a plurality of walls defining an interior volume, which walls are attached to one another in a reversible manner; and
a selectively openable side permitting movement of a product into and out of the interior volume of the container;
wherein the walls are formed from a thermoformed non-woven fabric that is a dimensionally stable fabric; and
wherein the container is collapsible and stackable and comprises a phase change material.
2. The container of claim 1 , wherein the interior volume of the container includes a receptacle in which the phase change material is contained.
3. The container of claim 1 , wherein the interior volume of the container includes receptacles in each of which the phase change material is contained.
4. The container of claim 1 , wherein the phase change material is not an integral part of the container.
5. The container of claim 4 , wherein the phase change material has a phase transition temperature between −50° C. and 0° C. at 1 atm, between 0° C. and 10° C. at 1 atm, between 2° C. and 8° C. at 1 atm, or between 5° C. and 10° C. at 1 atm.
6. The container of claim 4 , wherein the phase change material has a phase transition temperature between 50° C. and 95° C. at 1 atm.
7. The container of claim 1 , wherein the container further comprises an internal heating or cooling source other than the product.
8. The container of claim 1 , wherein the container further comprises an electrical power supply and/or electrical connector to provide active heating or cooling of the interior volume of the container.
9. The container of claim 1 , wherein: the walls defining the interior volume of the container define one or more holes; and the one or more holes are covered by a film.
10. The container of claim 1 , wherein one or more of the plurality of walls comprise a handle.
11. The container of claim 1 , wherein the container comprises one or more fasteners comprising one or more pairs of magnets.
12. The container of claim 1 , wherein the fabric comprises one or more polyesters, polyolefins, and/or polyamides.
13. The container of claim 1 , wherein the product comprises a food product and the container maintains the food product at a temperature between 65° C. and 75° C. for 60 minutes or a temperature between 90° C. and 150° C. for 2 to 8 hours.
14. The container of claim 13 , wherein the food product comprises pizza, fries, and/or chicken.
15. The container of claim 1 , wherein the product comprises a medical product and the container maintains the medical product at a temperature between 2° C. and 10° C. for 60 minutes.
16. A method of transporting a product, the method comprising: placing the product in the interior volume of the container of claim 1 ; transporting the product from a first location to a second location; and removing the product from the interior volume of the container.
17. The method of claim 16 , wherein the method does not comprise attaching the container to an electrical power supply.
18. The method of claim 16 , wherein the method does not comprise cooling or heating the interior volume of the container with a cooling or heating source other than the product.
19. The method of claim 16 , wherein the method further comprises heating or cooling the phase change material above or below a phase transition temperature of the phase change material prior to placing the product in the interior volume of the container.
20. A method of transporting product in a collapsible and stackable product transport container having a plurality of walls formed from a thermoformed non-woven fabric that is a dimensionally stable fabric, which walls are attached to one another in a reversible manner and define an interior volume of the product transport container, and which product transport container comprises a phase change material that is not located within the interior volume of the product transport container, the method comprising:
(a) charging the phase change material of the product transport container by heating the phase change material above a phase transition temperature of the phase change material;
(b) after charging the phase change material, placing a product in the interior volume of the product transport container by opening a side of the product transport container and inserting the product into the interior volume of the product transport container;
(c) transporting the product transport container with the product contained within the interior volume of the product transport container while passively heating the interior volume of the product transport container by the phase change material; and
(d) after transporting the product, opening the side of the product transport container and withdrawing the product from the interior volume of the product transport container; and
after performing said steps (a)-(d),
(e) again, charging the phase change material of the product transport container by heating the phase change material above the phase transition temperature of the phase change material;
(f) after charging the phase change material again, placing another product in the interior volume of the product transport container by opening the side of the product transport container and inserting the other product into the interior volume of the product transport container;
(g) transporting the product transport container with the other product contained within the interior volume of the product transport container while passively heating the interior volume of the product transport container by the phase change material; and
(h) after transporting the other product, opening the side of the product transport container and withdrawing the other product from the interior volume of the product transport container.
