Abstract
A bottle with an electrically-operated pump. The boxed cover containing dry cells, a motor and a switch, and the fistulous plug for stopping a mouth of a vacuum bottle are composed separately. The boxed cover hinges the upper and rear part of the vessel. The fistulous plug connects an inner pipe extending downward to an outer pipe extending laterally. A propeller shaft having a propeller at the lower end passes through the fistulous plug and the inner pipe. The rotation of the motor is transmitted to the propeller shaft by a clutch assembly.
