A vacuum insulated, heat retaining, liquid dispensing bottle which can readily dispense or supply water comprises an outer bottle body, a bottle cover, an internal bottle installed within and spaced from the outer bottle body providing the function of precluding heat loss, a siphon pipe extending deeply into the internal bottle, a discharge pipe with an end connected to the siphon pipe and a lower end extending out of the outer bottle body. The lower end of the discharge pipe is equipped with a discharge valve. The bottle is further equipped with a stopper having a compressed air mechanism. After liquid stored within the internal bottle fills the siphon pipe and the discharge pipe, liquid may be dispensed or not dispensed from the bottle by switching on or switching off the discharge valve provided outside of the bottle body.
A vacuum insulated, heat retaining bottle which can readily supply water from an erect position comprises an outer bottle body, a bottle cover, an internal bottle installed within the bottle body and spaced therefrom to preclude heat loss therefrom, a siphon pipe extending deeply into the internal bottle, a discharge pipe extending substantially entirely inside the outer body with an upper end connected to the siphon pipe and a lower end extending out of the outer bottle body, said lower end having a discharge valve, and said bottle having a stopper with a compressed air mechanism so that after the internal bottle is filled with water to the extent that the siphon pipe and the discharge pipe are filled, the bottle is enabled to discharge or stop discharging water when the discharge valve provided outside of the bottle body is switched on or switched off, wherein the bottle stopper is designed to be a centrally spaced ring housing, having an opening on its top side and air holes on its bottom side, said ring housing being equipped within its inner side with a ring shaped member closely engaging with the housing and extending upward as a pressing portion and including a coil compressed spring set on the bottom side of the ring shaped member within the housing.
A vacuum insulated, heat retaining bottle which can readily supply water from an erect position comprises an outer bottle body, a bottle cover, an internal bottle installed within the bottle body and spaced therefrom to preclude heat loss therefrom, a siphon pipe extending deeply into the internal bottle, a discharge pipe extending substantially entirely inside the outer body with an upper end connected to the siphon pipe and a lower end extending out of the outer bottle body, said lower end having a discharge valve, and said bottle having a stopper with a compressed air mechanism so that after the internal bottle is filled with water to the extent that the siphon pipe and the discharge pipe are filled, the bottle is enabled to discharge or stop discharging water when the discharge valve provided outside of the bottle body is switched on or switched off, wherein the inner side of the bottle cover is filled with insulation material precluding heat loss.
