Abstract

A closing member

3 is equipped with a dispensing valve

8 and a filter

7. The valve

8 is deformed resiliently to shift its valve head

82 downstream with its orifice

82

a remaining closed if pressure less than a first predetermined pressure and more than a second predetermined pressure is acted on the inner surface of the valve head

82. The valve

8 returns to its original shape to shift the valve head

82 upstream with its orifice

82

a remaining closed if the pressure is removed, thereby sucking fluid remaining within the passage

10 back to the upstream side of the filter

7. The closing member

3 has a supporter

31

d that prevents the orifice

82

a of the valve head

82 from opening when a negative pressure is generated in the bottle.
