【Abstracts】 An elastic sealed bottle cap with a flange at the top of the bottle is characterized in that the flange is gradually enlarged from the outer end to the root, that is, it is in the form of a cone-shaped circular table, and a circular hole is opened in the center. As a result of the above technical solution, the flange can be used to make the flange elastically receive and release when entering the liquid outlet hole at the top of the bottle body, and through the use of a conical circular table shape, the flange is smaller outside. The end is easier to insert into the outlet hole at the top of the bottle, while the larger inside end improves the sealing of the outlet hole at the top of the bottle body to completely prevent liquid leakage. The utility model has the advantages of simple structure, reasonable design, and good feeling of opening/closing cover body.
