When the reverse certain angle of rotation of stock solution lid 4, seventh recess 504 extrudees V type shell fragment 4015's non return shell fragment 4017, stock solution bottle 5 is parted by force with stock solution lid 4 to V type shell fragment 4015 in the eighth recess 4014 that leads to stock solution lid 4 is destroyed, thereby influence the sealing connection of stock solution bottle 5 and stock solution lid 4, and then lead to stock solution bottle 5 and stock solution lid 4 unable use, reach disposable purpose, prevent to be counterfeited.

The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics in the embodiments is not described herein. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practical applicability of the present invention. The scope of the claims of the present application shall be defined by the claims, and the description of specific embodiments and the like in the specification shall be used to explain the contents of the claims.
