The upper cover (1) connected to the lower cover (2) can be fastened on the lower cover (2), and the lower cover (2) has inner thread suitable to the bottle and is provided with a suction nozzle (3). There is a vent hole (5) on the lower cover (2),which can be sealed by a cone-shaped protuberance on the upper cover (1). A plastic spacer and a pad are located in the inner space of the lower cover (2). The pad impacts the plastic spacer to fix the plastic spacer in the inner space of the lower cover (2). The plastic spacer is configured as a concave ring with a cut. The concavity of the concave ring is a quarter of a semicircle. Holes are arranged on the pad uniformly. There is a lock structure between the upper cover and the lower cover. The bottle closure can avoid the liquid to spill out from the bottle and makes it easy to drink the liquid in the bottle.</p> |
