Thermally insulated container

Abstract

A thermally insulated container is provided which includes a tubular inner container part having a closed bottom and an open top end; a tubular outer container part having a closed bottom and an open top end, for receiving therein the tubular inner container part; and a connection member. With the inner container part received in the outer container part, the connection member is disposed between an upper end portion of the inner container part and an upper end portion of the outer container part to define a sealed space having a predetermined size between the outer peripheral surface of the inner container part and the inner peripheral surface of the outer container part.
