The product container assembly includes an exterior frame and an interior container forming a floor and side panels defining an interior region. Openings to the interior region are defined opposite the floor. Airflow paths are defined at an exterior of the panels and are fluidly connected to the interior region via the opening. The thermoelectric assembly includes a thermoelectric device connected to a heat sink that is fluidly connected to the airflow path away from the opening. A fan is positioned to circulate air from the thermoelectric device and into the interior region via the airflow paths.Type: GrantFiled: November 17, 2008Date of Patent: November 9, 2010Assignee: General Mills, Inc.Inventors: George A. Tuszkiewicz, Galen Hersey, Thomas P. Meehan, Mark Bedard

Publication number: 20100186423Abstract: A temperature controlled food storage unit is provided with a Peltier device (18) to effectuate the temperature of food place in a thermally conductive container or basin (24). Air from a fan (52) is passed through an air duct (50) and over a heat sink (22), which is thermally coupled to one side of the Peltier device (18). A hand-operated damper (54, 64) is used to control the air flow through the air duct (50) and over the heat sink (22) thereby controlling heat exchange between the Peltier device (18) and ambient air.Type: ApplicationFiled: January 23, 2009Publication date: July 29, 2010Applicant: PRINCE CASTLE INC.Inventors: LOREN VELTROP, DONALD VAN ERDEN

Patent number: 7764497Abstract: A transit container, such as a rack-mount style container, includes a temperature control system for maintaining a desired temperature within the container such that any cargo within the container remains operational at selected times and possibly in selected locations. The temperature control system includes support or mounting brackets, a temperature control assembly, shock isolation devices for shock attenuation of the temperature control assembly, exhaust assemblies that include exhaust fans and exhaust/intake louvers, and a mounting plate attachable to a lid of the transit container. The temperature control assembly and the aforementioned components may be arranged to have a low-height profile or envelope, which in turn permits the temperature control system to be located in a cavity or chamber of the lid.Type: GrantFiled: February 11, 2009Date of Patent: July 27, 2010Assignee: Environmental Container Systems, Inc.Inventor: Dennis M. Becklin

Patent number: 7748223Abstract: A constant temperature liquid bath using a thermo-module in which even if an article whose temperature is to be controlled exists in the bath, the temperature of the liquid is efficiently adjusted to a constant value. The liquid bath includes an outer bath storing the liquid, an inner bath disposed in the outer bath through a gap, and including holes in its sidewall through which the liquid flows into the inner bath from the outer bath and an opening at a central portion of its bottom, and an agitator that causes the liquid to flow upward from the opening of the bottom of the inner bath between sidewalls of the inner and outer baths by a rotor blade disposed on a central portion of a bottom between the outer bath and the inner bath. The thermo-module is mounted on an outer surface of the sidewall of the outer bath.Type: GrantFiled: September 16, 2004Date of Patent: July 6, 2010Assignee: SMC CorporationInventor: Atsushi Minoura
