Abstract (en)
[origin: US6380524B1] The microwavable shipping and/or retail package described here for heating food includes a material suitable for use in a microwave oven. The food disposed in the package is preferably at least partially raw. Taking into account the water content of the food, enough liquid is present in the package for the food to be cooked in a steam atmosphere which develops in the package when heated in a microwave oven. The package has a one-way valve in a wall, which opens automatically to the outside when there is an internal excess pressure, then closes again automatically after the pressure drops, thus limiting and/or reducing the vapor pressure that develops in the package during heating in a microwave oven. The valve membrane may automatically open and automatically close until the membrane deforms during heating, thereby causing said valve to remain open.
