The carrying means is composed of a rectangular insertion plate having a width at least substantially the same as the outer diameter of the neck portion and a fitting portion at an end thereof that are integrally formed from a flexible thermoplastic material in an L-shape, the fitting portion having a pair of holding pieces of the same shapes with inner circumference thereof having the same diameter as the diameter of the ring-shaped groove and end opening being narrower than the diameter of the ring-shaped groove.
