The present invention while improving the duration of cold effect provides a portable compact cold container capable of preventing the influence on the lid due to the freezing of the refrigerant. A lid 5 has a hollow portion 11, it is arranged refrigerant 13 and the shock absorber 15 in the hollow portion 11. That is, the cover body 5 and the refrigerant 13 and the shock absorber 15 are integrated. The refrigerant 13 in the lower portion of the hollow portion 11 is disposed, the shock absorber 15 is disposed in the upper portion of the hollow portion 11 between the refrigerant 13 and the lid 5. Shock absorber 15 absorbs an impact caused by the volume increase or the movement of the refrigerant 13, and has a heat insulating property. Opening of the container body 3 is closed in a sealed state by the lid 5 of the removable. .BACKGROUND
