Description

Technical Field

[0001] The utility model particularly relates to a storable bottle cap with a compact structure. Background Art

[0002] Most beverage bottles on the market are equipped with bottle caps. Consumers can drink the beverage by unscrewing the bottle cap after purchasing it. However, some beverages require auxiliary materials such as seasonings. Therefore, detachable bottle caps have emerged. Separate beverage bottle caps usually place seasonings in advance in the internal cavity of the bottle cap. Consumers can blend the seasonings with the solution to form a beverage by themselves after opening the bottle cap. The inventor has previously developed a detachable 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. By moving the storage barrel, its bottom end is separated from the bottom of the outer sleeve, so that the auxiliary materials stored in the storage barrel flow out and flow into the beverage in the beverage bottle. The specific structure can be referred to the patent scheme with patent number CN202120700091.5 and the name of a detachable bottle cap. However, during this separation, the bottle cap cooperates between the storage barrel and the outer sleeve through the spiral groove and the protrusion, so that the storage barrel can move up and down when it rotates. However, this bottle cap has a complex structure and a large volume, and the cooperation structure of the spiral groove and the protrusion is exposed, which is easy to cause pollution.
