Description

Technical Field

[0001] The utility model specifically relates to a separate type bottle cap leak-proof sealing structure. Background Art

[0002] Most of the beverage bottles on the market are provided with bottle caps. Consumers can drink the beverages by unscrewing the bottle caps after purchasing the beverages. However, some beverages require auxiliary materials such as additives, so separate bottle caps have appeared. Separate beverage bottle caps usually place additives in advance in the internal cavity of the bottle cap. Consumers can blend the additives with the solution into beverages by themselves after opening the bottle cap. The inventor has previously developed a separate bottle cap, which includes an outer sleeve with a closed bottom and a storage barrel arranged in the outer sleeve. The storage barrel is connected to the outer sleeve by a movable connection. In the initial state, the bottom end of the storage barrel is against the bottom of the outer sleeve. The storage barrel is separated from the bottom of the outer sleeve by moving the storage barrel, so that the auxiliary materials stored in the storage barrel flow out and flow into the beverage in the beverage bottle. However, due to processing errors and material deformation, the auxiliary materials in the storage barrel may leak out during transportation or sales, which causes a small amount of auxiliary materials to seep into the beverage, which will affect the actual shelf life of the beverage.

[0003] The utility model is produced based on the above-mentioned shortcomings. Utility Model Content
