Why Is It So Difficult For Children To Open Our Childproof Glass Jar Caps?

Why is it so difficult for children to open our childproof glass jar caps?

  1. The caps inner has been designed a wheel gear instead of some line.Through do this, there will be more tight seal and won't be opened by a child's easy rotation.

  2. In order to maintain the rigidity of the sealing ring, we matched hundreds of materials, and finally made the inner ring hard but not easy to break.
