Multi-layer container bottle with vacuum pump

The invention belongs to a liquid container, and provides a multi-layer container bottle with a vacuum pump. Due to the fact that when a liquid outlet pump in the prior art works, bacteria and dust in air outside the bottle enter the container bottle together with the air, and the defects that liquid in the bottle is oxidized, chemical components are changed, and the liquid in the bottle is contaminated by the bacteria in the air are caused. An outer bottle body (4) is made of non-deformable hard materials. A gas hole (5) is arranged on the outer bottle body (4). An inner bottle body (6) is made of shrinkable soft materials. The outer bottle body (4) and the inner bottle body (6) are tightly connected into a whole at the positions of bottle necks. A bottle cover (2) is connected with the bottle neck in a sealed manner. A liquid outlet pump penetrates the bottle cover (2). A pump body (3) and a liquid inlet pipe of the liquid outlet pump are arranged in the inner bottle body (6). The pump body (3) is a cylindrical sealing body. The multi-layer container bottle has the beneficial effects that the liquid in the bottle can not be oxidized by oxygen in the air, the chemical components can not be changed, the liquid in the bottle can not be contaminated by the bacteria in the air, and the effective use period of the liquid in the bottle is prolonged.
