<P>PROBLEM TO BE SOLVED: To provide a new jet head capable of preventing a conventional problem such as dripping. <P>SOLUTION: The jet head includes a base 2 having a passage r continuous to the stem 1 of a container and movable simultaneously with the movement of the stem 1, a head body 3 slidably held by this base 2 and having a discharge space m for the content inside thereof, and a nozzle pin 10 slidably and elastically supported along the shaft core inside the discharge space m of this head body 3, opening the jet port 5a of a nozzle 5 by the rearward slide accompanying the push-in of the head body 3, and jetting the content inside the container through the stem 1 and the discharge space m to the outside. The nozzle pin 10 is constituted of the trunk part 10b having the tip part 10a fit to the jet port 5a of the nozzle 5 to seal the jet port, and the rear end part 10c continuous to this trunk part 10b, slidably linked to a seal member 11, and keeping the inside space m liquid tight. The seal part of the rear end part 10c is set at the cross-sectional area S which is the cross-sectional area S<SB>1</SB>of the tip part 10a or smaller. <P>COPYRIGHT: (C)2009,JPO&INPIT |
