Multi-layer container bottle with vacuum pump

Abstract

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.

Description

technical field [0001] The invention belongs to a liquid container, in particular to a multilayer container bottle with a vacuum pump. Background technique [0002] Liquid containers are widely used in various industries, agriculture, medicine, cosmetology, teaching instruments and other fields. The liquid contained in the liquid container includes various chemical raw materials, chemical reagents, pesticides, liquid fertilizers, medicines, beauty and skin care agents, disinfectants and other products. The liquid container bottle of the present invention includes various container bottles, container jars, container barrels and the like widely used in modern society. [0003] Existing liquid container bottle is generally single-layer bottle body, adds the plug or cover of a sealed container to form. For the convenience of liquid outflow, people often install vacuum pumps on liquid containers, such as various perfume bottles, shampoo bottles, disinfectant bottles, and the li...

AI Technical Summary

Problems solved by technology

The disadvantage of the prior art is: when the vacuum pump works, bacteria and dust in the air outside the bottle enter the container bottle with the air, which brings the following consequences:

[0006] (3) The liquid in the bottle is polluted by dust in the air; reduce the quality of the liquid and reduce the use effect

[0009] The invention provides a liquid container bottle with a multi-layered body and a vacuum pump without air entering the container bottle when the liquid in the container flows out, thereby overcoming the liquid in the bottle being oxidized by air, changing the chemical composition, and affecting the use effect of the liquid ; shorten the effective life of the liquid; the liquid in the bottle is polluted by bacteria in the air; the liquid in the bottle is polluted by dust in the air; the disadvantages of reducing the quality of the liquid and reducing the use effect
