An ice container is provided to remove a spot that has not been heat exchanged and buoyancy and to improve heat exchange efficiency by not making a damping air layer in a filing unit. An ice container comprises a container body(11a), and an expansion unit(20a) wherein a neck unit(22a), an extension unit(23a), and a lower bent unit(24) are integrally formed. The container body has a hollow filling unit(30) where a freezing solution is filled up. The expansion unit is piled in the filling unit of the ice container. The neck unit has an opening where refrigerant is injected. The extension unit is formed at a lower part of the neck unit, bears the expansion pressure when the freezing solution is frozen and is recovered by elasticity when the freezing solution is melted. The extension unit has extension space connected to the opening of the neck unit. The lower bent unit is formed at the lower part of the extension unit to reduce tension. |
