chemical solution, a nozzle member (30) coupled with a stem (24) for open operation
of the valve mechanism (20) and having a chemical solution drip nozzle (31), an
operating member (40) provided with an operating piece (41) and attached to the
container body (10), a guide member (51) contained in the operating member (40)
and guiding the nozzle member (30) in the axial direction, and a ball (52) contained
