Patent abstract
A mouthpiece of a water bag includes a flexible body with a tunnel therein, a closed end at an end of the flexible body, and an elongated crack on the closed end adapted to communicate the tunnel, whereby the crack is closed at a normal condition and is opened when the flexible body is compressed along an elongated direction of the crack, a cap detachably covering the closed end of the flexible body, which has a strip and a ring fitted to a slot on the flexible body. The cap may isolate dust from the close end of the flexible body that keeps the crack clean. The crack is closed in a normal condition, and the ring fitted to the flexible body may restrict the flexible body to ensure the crack closed.
