TECHNICAL FIELD

[0001] The application relates to the technical field of bottle caps, in particular to a solid-liquid dual-storage separation type multifunctional bottle cap. BACKGROUND

[0002] With the rapid development of the times and the rapid improvement of economic and industrial levels, people's living quality requirements are increasingly improved, and the types of beverage products are increasingly diversified. Currently, the beverages commonly seen on the market are mostly pre-brewed, and have the problems of insufficient freshness and short shelf life. Some new beverage products need to mix solid flavoring agents or nutritional supplements with liquid before drinking, but the existing bottle caps cannot realize solid-liquid separation and storage.

[0003] There are currently available solid-liquid separation type bottle caps and honey separation type bottle caps on the market. The bottle caps pre-store brewing powder or honey, which is separated from the liquid in the beverage bottle, so as to achieve the effect of brewing and drinking at the same time and guarantee the freshness of the beverage. For example, the patent with the publication number CN220375255U discloses a solid-liquid separation type multifunctional bottle cap, which comprises a sealing assembly, a receiving assembly and a storage assembly. The solid in the bottle cap is mixed with the liquid in the bottle by rotating. The patent with the publication number CN118637198A discloses a multifunctional honey water separation type bottle cap. When the bottle cap is used, the adjusting rod is pulled out to reduce the volume of one chamber, increase the pressure and break the liquid bag. The honey flows into the other chamber. The adjusting rod is inserted to reduce the volume of the chamber and increase the pressure. The honey flows into the water.

[0004] However, the above-mentioned separation type beverage bottle caps have certain limitations. Although they are convenient and sanitary, they can only store solid or honey and cannot solve the problem of simultaneous storage of solid powder and honey. Therefore, based on the above limitations, we have developed a solid-liquid dual-storage separation type bottle cap to solve the problem of simultaneous storage of solid powder and honey.
