PROBLEM TO BE SOLVED: To prevent the top surface of the mouth part of a bottle from being damaged while it is being transported after molding or packed in a box because the bottles collide with one another, in the liquid-pouring-out container and further, prevent the internal stopper from forming cracks in the fitting part of the internal stopper cylinder when driving the stopper so as not to leak liquid. SOLUTION: The liquid-pouring-out bottle is constituted of a bottle equipped with engaging protrusions around the upper periphery of the mouth part, an internal stopper equipped with an engaging tube part to be engaged with the protrusions and a pouring-out tube, and a cap, and is characterized in that the angular edge part between the outer periphery of the top surface of the mouth of the bottle and the outer periphery surface of the protrusions is rounded, to give a smooth curved surface. |
