ABSTRACT:
A vacuum bottle container of the kind having an air pump adapted to feed air into the interior of the vacuum bottle to increase the internal pressure in the bottle, whereby the liquid in the vacuum bottle is poured without inclining or holding up the container. The vacuum bottle comprises a cylindrical body member, a vacuum bottle disposed in the body member, a hollow stopper having a downwardly-extending pumping tube and a transversely-extending pouring tube communicated thereto, and a hollow lid body pivotally mounted on the body member, said lid body including an air pump, a motor for operating the air pump, a battery and a switch connected in the motor driving electric circuit, the lid body being provided at its bottom with an air outlet, a vapor outlet, and a chamber communicated to the interior of the vacuum bottle through the air outlet and to the atmosphere through the vapor outlet. The vapor outlet may be closed before or simultaneously with the closing of the motor driving electric circuit by a valve adapted to be operated by a device for actuating the switch. The provision of the vapor outlet makes it possible to prevent the natural outflow and extra pouring of the liquid in the vacuum bottle.
