Abstract
Abstract In a refrigerating container of the present invention, an inner lid with freezing material is slidably and closely engaged in the inside wall of an inner box, the inner lid and the inner box being made of closed-cellular synthetic resin foam. The inner lid is pressed down to touch the contents to minimize the space between the inner lid and the contents and to increase freezing effect.
