PROBLEM TO BE SOLVED: To provide a rubber stopper for a medicinal/medical container, wherein a bottom of a recess of a stopper leg, which is brought into contact with a liquid medicine, can be favorably washed even in the case where the stopper is small in size, in a rubber stopper for a medicinal/medical container, which has a top cover and a projecting cylindrical stopper leg provided on the underface of the top cover. SOLUTION: The rubber stopper for a medicinal/medical container has at least three openings which are defined in a stopper leg having a recess in the center thereof and which are provided at substantially equal angle intervals toward a top cover from the top end portion thereof. When the stopper is washed in a washing bath, a wash liquid stream is produced which reliably reaches a bottom of the recess of the stopper leg irrespective of not only a posture of the rubber stopper but also the direction of the wash liquid stream, and a washing effect can be thereby heightened. It is most preferable to provide four openings in number. |
