PROBLEM TO BE SOLVED: To hold liquid contents left in spout passages after pours less liable to cool down. SOLUTION: A delivery passage 25 is defined to extend in a vacuum space 9 of a vacuum double container 3, to extend along the external surface of the shell of the vacuum double container 3 which does not form the vacuum space 9, to be exposed to the internal or external surface of the shell of the vacuum double container 3 to which it joins to form a part of the shell, or to extend along the internal surface of an inner cylinder 4 of the vacuum double container 3. The heat of liquid inside the inner cylinder 4 is thus transferred by radiation or conduction to liquid left in the delivery passage 25.
