<P>PROBLEM TO BE SOLVED: To provide a delivering pump which reduces the fluctuation of the amount of delivery and prevents a content from being discharged by an accidental external force. <P>SOLUTION: A pushing-down head 12 attached on a stem 15 so as to be turnable around a central axial line O and provided with a storing room 34 in which the content delivered through the stem 15 is stored, and a screw cap 11 arranged outside in the radial direction of the pushing-down head 12 are provided. A guide channel 35 is formed along the peripheral direction on the peripheral face of the pushing-down head 12, and a guide projecting part 24 which is guided along the guide channel 35 and vertically moves the pushing-down head 12 is provided on the peripheral face of the screw cap 11. The guide channel 35 has a first guide channel 36 which moves the pushing-down head 12 with the stem 15 downward more than a reference height with respect to the screw cap 11 accompanied by the turning of the pushing-down head 12 around the central axial line O, and a second guide channel 37 continuously formed in the peripheral direction with the first guide channel 36 and upwardly moves the pushing-down head 12 to the reference height. <P>COPYRIGHT: (C)2009,JPO&INPIT |
