Claims

[Claims for Utility Model Registration] 1. A container consisting of a container body and a lid made of foamed synthetic resin, one of which has a fitting structure at the joint between the container body and the lid, and this fitting structure at the other. The other side of the fitting structure is provided to be fitted to one side of the container, and a ventilation gap of a required length is provided in the longitudinal direction of this fitting structure between one side of the fitting structure and the other when the container is closed. An inner opening is opened from inside the container toward this ventilation gap, and a through hole is bored from the top surface of the lid toward the ventilation gap by displacing the inner opening. A cold storage container for vacuum precooling, which has an opening on the outside, and when the lid of the container is closed, the inside and outside of the container communicate through the opening on the inside, the ventilation gap, and the opening on the outside. 2. The vacuum precooling cold storage container according to claim 1, wherein the ventilation gap is formed from a groove provided in one and/or the other of the fitting structure. 3. A claim that the cross-sectional area and length of the ventilation gap are formed to such an extent that when there is almost no pressure difference between the inside and outside of the container, free flow of air is substantially blocked by viscous resistance and film frictional resistance. Item 2. A cold storage container for vacuum precooling according to item 1 or 2.
