  • Water pail equipped with air passageway
    Publication number: 20010019057
    Abstract: A water pail is equipped with an air passageway in a stopper to pass through external air so that contents contained in the water pail are smoothly exhausted out. Since the air passageway is provided to flow the external air into the stopper of the outlet, the contents contained in the water pail are smoothly exhausted out, thereby preventing the contents from being splashed out. Also, the production cost of the water pail can be reduced.
