Description

Cap of bottle {

The present invention relates to a bottle cap, and more particularly, to a bottle cap that the user can easily check the opening state of the cap after the cap is opened.

In our daily life, a bottle, which is mainly used to contain liquids, is a generic name for a narrow-necked bowl. It is usually a bottleneck of narrow shape as the diameter decreases gradually from the bottom of the tubular body to the upper end. It forms a bottle neck with an open mouth at its end. Therefore, the desired material can be injected and stored through the bottle opening, and the contents can be discharged from the inside of the bottle with the bottle opening facing downward.

On the other hand, the bottle opening of a common bottle is sealed with a bottle cap to improve reliability of storage / preservation and storage of the contents, and the bottle cap may be a crown, a cap, a cover, a lid, or a closure. Also called), it can be classified in various ways based on its material, shape, or use.

By the way, in the case of a general bottle cap, when the bottle is opened again and then repackaged, there is a problem that the user cannot confirm the open state of the bottle.
