Because it has a vacuum.
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.

It will become vacuum sealed, and opening the bottle will cause a sudden release of low pressure, where higher pressure air from it's surroundings is 'sucked' into the bottle, equalizing the pressure.
just get a vacuum water bottle !!! cheers >.<
why are vacuum flasks called vacuum flask
The main idea is to reduce the heat transfer out of the vacuum bottle, or into it. A vacuum greatly reduces the transfer of heat by conduction and convection, while the mirror reduces heat transfer by radiation.
because there is is a pressure difference between the inside of the bottle and the outside. the pressure is lower in the bottle the egg gets sucked in. when the oxygen is burned there is less matter in the bottle then at first and that results in less pressure[vacuum]
Found it myself; the answer is thermos.
