<p>PROBLEM TO BE SOLVED: To obtain a refill bottle wherein a liquid can be refilled quickly without being scattered around and production is easy with a simple structure by providing, on a lower portion of an outer periphery of a neck, a projecting flange which can be locked in contact with an upper surface of a mouth of a container to be refilled in an inverted state and by providing an exhaust path for exhausting substitution air on the flange. SOLUTION: A neck 4 of a bottle A can be inserted into a mouth of a container, a flange 6 which can be locked in contact with an upper surface of the mouth of the container in an inverted state is made to project at a lower portion of an outer periphery of the neck 4, and while the bottle A is in an inverted state with the neck 4 inserted into the mouth of the container, the flange 6 can be locked in contact with the upper surface of the mouth of the container for allowing a liquid to be refilled. An exhaust path (a) for exhausting substitution air is provided on the flange 6, so that the substitution air can be discharged outside through the exhaust path (a) from a gap between the outer periphery of the neck 4 and an inner periphery of the mouth of the container in place of the liquid injected into the container to be refilled. Thus the liquid can be quickly refilled into the container without being dripped.</p> |
