A safety mechanism system for double vacuum bottle construction to prevent liquid contained within the inner bottle element from escaping when the system is upset or overturned and including a cover portion disposed directly above and in contact with the body portion of the bottle, a bellows to serve as a pump provided inside the cover with the lower portion of the bellows in communication with the inside part of the cover and in further communication by an air valve and air vent with the inner portion of an inside bottle of the double bottle vacuum system, with a cylinder in vertical arrangement with the bellows and inner bottle member and located within a plug member for the mouth of the inner bottle, and adjacent to the cylinder a chamber connected by apertures to the inside of the inner bottle, as well as a receiving portion adjacent to the cylinder and in vertical relation therewith and containing therein blades projected therefrom and having a closing element adapted to cooperate with said receiving portion and the blades for opening and closing the receiving portion in contact with a liquid-draw-up pipe and a liquid pouring pipe such that, in operation, the weight and arrangement of the closing element is so oriented as to function in a manner to permit passage of a liquid due to pressure exerted thereon unless the system is upset or overturned.
