These products include: mixed drinks, food, medicine, cosmetics, milk formula, nutritional products, supplements, mixed-use gums, etc. The products used after mixing these products cannot maintain the activity, stability, effective usability and strength for a long time after mixing. If they are isolated separately, they can be stored for a long time. This requires a packaging and storage device that can not only realize separate packaging, but also allow users to carry conveniently and easily in the process of use. As a carrier for packaging and storage of the above products, storage bottles that are easy to mix and carry are favored by many manufacturers. In storage bottles, storage bottle caps are usually used to seal storage bottles, but existing storage bottles The cap has the following defects: poor sealing, which causes the contents of the storage bottle to agglomerate due to moisture; the assembly process between components is complicated, resulting in increased costs; the overall structural design is complicated, and the user is difficult to use; for example: a. Pressure resistance Too large, it is difficult to use; b. During use, it is necessary to unscrew the bottle cap, and then open the storage bottle cap, and pour the contents of the bottle cap into the bottle. This process is complicated, and the Substances are easy to leak out, and ultimately cannot reach the predetermined ratio; c. Operation is unstable.

Summary of the invention

The present invention relates to a storage-type bottle cap with anti-misoperation, which solves one or more of the above technical problems.

A storage-type bottle cap with anti-misoperation includes: an upper cover body 1, a lower cover body 2, and a sealing sheet 3; the sealing sheet 3 is heat-fixed in the upper end sealing sheet receiving recess 11 of the upper cover body 1. Or, the sealing sheet 3 and the upper end of the upper cover body 1 are an integrally formed sealing structure, and the upper cover body 1 and the lower cover body 2 are threadedly connected; the upper cover body 1, the lower cover body 2, and the sealing sheet 3 are enclosed by a formula material ( The formula object can be a storage cavity of powder, solid, or liquid). The upper cover includes an outer cover cylindrical cover 12 and an inner ring-shaped piercing structure 16 connected by a planar connection bridge 13. 11 is located inside the connecting bridge 13. The lower end surface of the cylindrical cover 12 of the upper cover is connected with a tearing C ring 15 through a small connecting column 14. The lower end edge is provided with puncturing teeth 161; the lower cover 2 includes an inner connection ring 21, an outer lower cover cylindrical cover 22, a spacer 23 sealed and fixed at the lower end of the connection ring 21, and an upper portion of the connection ring 21 is processed outside The lower cover is externally threaded 211, the inner side of the lower end is sealed and fixed with a spacer 23, and the lower cover cylindrical outer cover 22 The inner thread of the lower cover 221 is processed on the side; the upper part of the connecting ring 21 in the lower cover 2 is inserted into the inside of the upper cover cylindrical cover 12 in the upper cover 1 and the position between the annular piercing structures 16 passes through the upper cover. The thread engagement of the thread 121 and the outer thread 211 of the lower cover realizes the connection of the upper cover 1 and the lower cover 2 and at the same time seals the storage cavity for storing the formula substance; the assembly of the upper cover 1 and the lower cover 2 is completed. Next, the tearing C-ring 15 is located above the upper end face of the lower cylindrical cover 22 (the tearing C-ring 15 may or may not be in contact with the lower cylindrical cover 22).
