Therefore, the flange portion 15 of the rubber plug 12 can be pressure-bonded with sufficient strength between the tubular portion 9 and the top thin film 11 of the mouth portion 5 and the step portion 20 of the outer frame member 13. As a result, the rubber stopper 12 can be firmly held by the flange portion 15.
