The nozzle 2 is constituted with a discharge tube part 2a provided on the end side thereof and a wider diameter tube part 2b provided on the root side thereof. The cap 4 includes at least a fitting cylinder part 4a for externally fitting to the wider diameter tube part 2b of the nozzle 2 and a top plate part 4b for covering the upper end side of the fitting cylinder part 4a. Protrusion(s) 5a for sealing is/are circumferentially provided near the upper end of the outer circumference of the wider diameter tube part 2b and/or near the lower end of the inner circumference of the fitting cylinder part 4a. |
