Abstract

A multi-component package is provided which enables simultaneous heat cooking of a food product which does not require a long cooking time and a food product which requires a longer cooking time. The multi-component package includes a lower container having a bottomed, lower container main body for containing a first food product. The container further includes an upper container having an upper container main body for containing a second filled food product. A flange of the lower container main body and a flange of the upper container main body are engaged with each other so that the lower container and the upper container are combined integrally. A vapor vent is provided in a lower container lid material, whereby water vapor generated upon heating of the first food product heats the second food product in the upper container.
