Abstract: Thermal protection for sensitive items stored for extended periods of time in a passenger vehicle is a requirement that has not been adequately addressed by the industry. A primary object of this invention therefore, will be to provide a convenient and versatile means for forming and integrating a storage container employing appropriate phase change materials to create a controlled temperature environment for heat-sensitive articles inside an automobile, truck, or other enclosed road vehicle. As such, the invention will afford protection where summer temperatures build up to levels inside the stationary vehicle which could exceed safe limits for heat sensitive items that might be stored in the vehicle for an extended period of time; ie an hour or more. An additional optional objective will be to further include a phase change material with a substantially lower melting point to protect sensitive items from freezing during the winter months.
