COLD INSULATING BEVERAGE CONTAINER

PROBLEM TO BE SOLVED: To provide a cold insulating beverage container which is improved in storage efficiency in a refrigerator and suppresses dew condensation while exhibiting high cold insulating performance. SOLUTION: An outer vessel 1 and an inner vessel 3 fitted into the outer vessel 1 are constituted of materials different in specific heat. The cold insulating beverage container comprises a double wall formed of the outer vessel 1 as an external wall and the inner vessel 3 as an internal wall. A container engaging protrusion 4 is made to protrude in a horizontally radial direction on an external bottom face or an external side face of the inner vessel 3, and a container engagement receive 5 into which the protrusion 4 is inserted from a horizontally circumferential direction is provided on an internal bottom face or an internal side face of the outer vessel 1. The inner vessel 3 inserted into the outer vessel 1 is rotated thereby inserting the protrusion 4 into the receive 5 and having the inner vessel 3 fitted into the outer vessel 1.
