The bottle cap (10) and the bottle neck (20) are connected by a cap connecting member and a neck connecting member. The bottle cap (10) comprises a cap top and a cap wall. Inside the cap wall are provided the cap connecting member and a cap sealing member under the cap connecting member. The bottle neck (20) comprises a neck wall. Outside the neck wall are provided the neck connecting member conjugated with the cap connecting member and a neck sealing member under the neck connecting member. When the connection between the bottle cap (10) and the bottle neck (20) is accomplished by the cap connecting member and the neck connecting member, a cap top closed plane (4) is closed by a neck top face (14) to make up a first sealing ring and the cap sealing member is closed by the neck sealing member to make up a second sealing ring. The outer edge of the bottle neck after closing the bottle cap keeps out dust and bacteria, thus ensuring hygienic bottle neck during usage condition.
