Description

bottle cap

【Technical field】

The utility model relates to a matching part of a bottle, in particular to a bottle cap.

【Background technique】

Now, due to the increase in the price of petroleum raw materials, the production cost of bottle caps has increased sharply, so many bottle cap manufacturers have decided to reduce costs, and the most direct way to reduce costs is to reduce the amount of raw materials, but reducing raw materials will inevitably cause the wall of bottle caps to become thinner , strength and quality deteriorate.

【Content of invention】

In order to overcome the shortcomings in the background technology, the utility model discloses a bottle cap, which can achieve the purpose of reducing production cost.

In order to realize the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

A bottle cap, which includes a cap body, the cap body is composed of a cap cylinder body and a cap bottom, the inner wall of the cap cylinder is provided with threads, and the outer wall of the cap body is provided with evenly distributed protrusions.
