What Is The Make Method Of Silicone Bottle Caps?

It consists of a silicone cap with a flared bottom end and two or more rings on the inside of the cap, which are threaded together with the bottle mouth on the outside.

As the cap is made of silicone, which is soft and flexible, it can be used to seal the liquid inside the bottle by pushing down the cap directly on the mouth of the bottle, and in addition, the ring-shaped sealing ribs on the inside of the cap can bite together with the threads on the outside of the mouth of the bottle, which not only makes the cap won't fall off easily, but also further enhances the sealing effect; when you need to remove the cap, just flip the lower end of the cap outward and push upward at the same time, then the cap and the bottle can be separated from the contact, which is very convenient to use.
