Because it has a vacuum.
No scientists can hardly produce a close to perfect vacuum in a high tec. lab, So I very serously doubt you could make a perfect vaccum in a bottle.
the vacuum bottle works by having a vacuum trapped in between the lays of the bottle elimination 2 forms of heat radiation.
Another word for a vacuum bottle would be flasken.

Understanding the components of the vacuum bottle, one can be in better position of understanding the leakage. Microprocessor monitors leakage in the Vacuum bottle.

Take a metal cylinder, and place a spring in the bottom (as a shock absorber). Inside the metal cylinder, sitting atop the spring is a glass bottle. Between the cylinder and the bottle (around the sides and the bottom of the glass bottle) is a vacuum. Both the vacuum and the glass serve as insulators for anything that is to be stored in the glass bottle. This means that, if you store something warm in the inner glass bottle, it will be very difficult for the heat to conduct through the glass AND the vacuum...and the material will stay warm. If you store something cold in the bottle, it will be very difficult for heat to conduct through the cylinder, the vacuum, and the glass...and the material will stay cold.
just get a vacuum water bottle !!! cheers >.<
A vacuum bottle has a double-wall design with a vacuum between the inner and outer walls. This vacuum layer acts as insulation, preventing heat transfer between the inside and outside of the bottle. This insulation helps to retain the temperature of the food or drink inside, keeping it hot or cold for an extended period of time.
Found it myself; the answer is thermos.
