Description

Bottle cap capable of storing solid powder

Technical Field

The utility model belongs to the technical field of bottle caps, and particularly relates to a bottle cap capable of storing solid powder.

Background

At present, most of bottled beverages are prepared by pre-mixing all ingredients of the beverage, filling the beverage into a bottle for storage, and unscrewing the bottle cap when the beverage is drunk. However, this approach mostly requires the addition of preservatives to extend the shelf life of the beverage, which would be detrimental to health if the added amount of preservatives is large or if the beverage containing the preservatives is used in large amounts for a long period of time. Based on this, there is an increasing search for healthy products. In the market, a bottle cap capable of independently storing solid powder appears, the solid powder preset in the bottle cap and the liquid in the bottle are separately and independently stored, and the solid powder and the liquid in the bottle are mixed when needed.
