[0002] In the prior art, the bottle cap structure of the liquid preparation bottle is relatively simple, and most of them only have a single shell, and the liquid preparation and the outside air share a passage
When in use, the outside gas will enter the bottle with the backflow of the liquid preparation, and at the same time, bacteria, dust or other substances mixed in the outside air will enter the bottle and contaminate the preparation, causing the liquid preparation to deteriorate or cause the user Adverse symptoms such as allergies and infections appear, which affect the use effect

The invention relates to the field of packaging containers and particularly relates to a bottle cap and a liquid preparation containing bottle using the bottle cap. The bottle cap comprises a shell, a liquid path and a gas path, wherein the gas path and the liquid path pass through the shell and are communicated with the inside and the outside of the shell; the gas path is internally provided with a first one-way valve which enables a medium in the gas path to be transferred to the inner part from the outer part of the bottle cap; the gas path is internally provided with a first filtering device; and the liquid path is internally provided with a second one-way valve which enables a medium in the liquid path to be transferred to the outer part from the inner part of the bottle cap. The bottle cap and the liquid preparation containing bottle using the bottle cap disclosed by the invention can prevent external bacteria, tiny dust or other substances from entering the containing bottle.
Description
technical field [0001] The invention relates to the field of packaging containers, in particular to a bottle cap and a bottle for containing liquid preparations using the bottle cap. Background technique [0002] In the prior art, the structure of the bottle cap of the liquid preparation containing bottle is relatively simple, and most of them only have a single shell, and the liquid preparation and the outside air share a passage. When in use, the outside gas will enter the bottle with the backflow of the liquid preparation, and at the same time, bacteria, dust or other substances mixed in the outside air will enter the bottle and contaminate the preparation, causing the liquid preparation to deteriorate or cause the user Adverse symptoms such as allergies and infections appear, which will affect the effect of use. Contents of the invention [0003] The invention provides a bottle cap and a liquid preparation containing bottle using the bottle cap. [0004] The bottle c...
