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 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, sensor having a power source within the container, comprising the steps of:

a. sensing the temperature by the sensor in the interior of the container when the insulated closure member is in place to close the receptable, the data monitor adapted to generate a temperature data signal; and

b. transmitting the temperature data signal from the sensor to a central receiver located at a location remote from the container and the monitor.

2. The method of claim 1, in which the step of transmitting the temperature data signal to the central receiver is performed using wireless communication.
