<P>PROBLEM TO BE SOLVED: To provide a cap capable of changing a pouring flow rate from a pouring bore by guiding a relative axial position between an inner cap body and an outer cap body in multi-stages. <P>SOLUTION: The cap has an inner cap body 20 equipped with an inner cylindrical part 23, and an outer cap body 30 mounted so as to be elevated and lowered axially to the inner cylindrical part 23 and to be rotatable circumferentially. Peripheral guide parts 12 for guiding peripheral positions each other and axial guide parts 11 for guiding axial positions in accordance with the peripheral direction positions are respectively provided on the inner cap body 20 and the outer cap body 30. The peripheral guide part 12 is equipped with a projecting part 38 and a plurality of locking parts 27 for engaging with the projecting part 38 and guiding the peripheral position. By rotating the outer cap body 30 to change the axial position between the inner cap body 20 and the outer cap body 30, the flow quantity of discharging from a spout 34 is switched at least by three steps. <P>COPYRIGHT: (C)2008,JPO&INPIT |
