Abstract

An advanced thermal container has a thermally insulated open receptacle, a thermally insulated closure member, a data monitoring system incorporated into the container that can send and receive information via wireless communication, and a sealing system to minimize heat transfer and air exchange between the interior and exterior of the container. Hard plastic casing enclosing foam-encased vacuum insulation panels is used to construct the insulated receptacle and closure member. The closure member and receptacle each have an elongated portion with shoulders above and below the elongated portion. When the container is closed, a lower seal and an upper seal are compressed between the mating lower and upper shoulders, respectively. The onboard data monitoring system records important parameters concerning the internal and external environments of the container, particularly temperature information, as well as other significant events such as the number of times the container was opened during transit.

Claims

1. A thermal container comprising:

an open receptacle defining a chamber surrounded by walls formed of thermal insulation material, the receptacle having an opening surrounded by a perimeter, the perimeter having first and second shoulders facing toward the opening and separated by a transition surface that is transverse to the shoulders; and

a closure member having a layer of thermal insulation material for opening and closing the receptacle, the closure member having a perimeter having first and second shoulders that mate with and seal the shoulders of the receptacle and a transition surface located between the shoulders of the closure member that mates with the transition surface of the receptacle.

2. The thermal container of claim 1 in which the thermal insulation material comprises at least one vacuum insulation panel surrounded by a layer of foam insulation.

3. The thermal container of claim 1 in which the first and second shoulders of the receptacle are parallel to each other and the transition surface of the receptacle is substantially perpendicular to the first and second shoulders of the receptacle.

4. The thermal container of claim 1 in which the transition surfaces of the receptacle and closure member each have a dimension from the first and second shoulders of the receptacle and closure member, respectively, that is greater than a width of either the first or second shoulder of the receptacle and closure member, respectively.

5. The thermal container of claim 1 further comprising a data monitor incorporated into the container to monitor physical parameters within the chamber of the receptacle.

6. The thermal container of claim 5 in which the data monitor further comprises a battery for electrical power, a central processing unit to process and output information, a transmitter to transmit the output information to a remote central receiver, a memory storage device to store and record the output information, and at least one temperature sensor to sense the temperature within the chamber of the receptacle.

7. The thermal container of claim 6 in which the data monitor further comprises a receiver to receive information from a remote central transmitter.

8. The thermal container of claim 7 in which the transmitter and the receiver use wireless communication to transmit and receive, respectively.

9. A thermal container comprising:

an open receptacle defining a chamber surrounded by walls comprising at least one vacuum insulation panel surrounded by a layer of foam insulation, the receptacle having an opening surrounded by a perimeter, the perimeter having first and second shoulders facing toward the opening and separated by a transition surface that is transverse to the first and second shoulders;

a closure member for opening and closing the receptacle, the closure member comprising at least one vacuum insulation panel surrounded by a layer of foam insulation and having a perimeter having first and second shoulders that mate with and seal the shoulders of the receptacle and a transition surface located between the first and second shoulders of the closure member that mates with the transition surface of the receptacle; and

a data monitor incorporated into the container having a battery for electrical power, a microprocessor to process information, a transmitter to transmit an electromagnetic signal to a remote central receiver, and at least one sensor to sense temperature within the chamber of the receptacle.

10. The thermal container of claim 9 in which the data monitor can transmit information via wireless communication.

11. The thermal container of claim 9 in which the data monitor further comprises a receiver to receive an electromagnetic signal.

12. The thermal container of claim 11 in which the data monitor can receive information via wireless communication.

13. A thermal container comprising:

an open receptacle defining a chamber surrounded by walls;

a closure member for opening and closing the receptacle;

a data monitor incorporated into the container having a battery for electrical power, a microprocessor to process information, a transmitter to transmit an electromagnetic signal to a remote central receiver, a receiver to receive an electromagnetic signal from a remote central transmitter, and at least one sensor to sense a physical parameter regarding the container.

14. The thermal container of claim 13 in which the data monitor can transmit and receive information via wireless communication.

15. The thermal container of claim 13 further comprising a seal between the closure member and the receptacle.

16. The thermal container of claim 13 in which the sensor senses the warmest temperature within the chamber.

17. The thermal container of claim 13 in which the sensors sense the warmest temperature within the chamber and the number of times the receptacle is opened.

18. A method of maintaining a thermal environment in a container having a thermally insulated receptacle defining an interior and an exterior of the container, a thermally insulated closure member to open and close the thermally insulated receptacle, and an onboard, battery-powered data monitor, comprising the steps of:

sensing the temperature; and

transmitting the temperature sensed to a central receiver.

19. The method of claim 18 further comprising the step of recording the temperature with the onboard, battery-powered data monitor.

20. The method of claim 18 in which the step of transmitting the temperature sensed to the central receiver is performed using wireless communication.
