<P>PROBLEM TO BE SOLVED: To provide a pump type pressure ejector capable of controlling the contact of a resilient member with the content which biases the upper part of the nozzle head while reducing the number of component required for composition. <P>SOLUTION: The pump type pressure ejector includes the pump 3 suspended by a base cap 1 screwed and fixed in the mouth portion of the container and pumps up the content, and the nozzle head 4 driving the pump 3 drive and discharging the content to the external field. The ejector is provided with an adapter 2 integrally and separably connected to the base cap 1, detachably engaged with the nozzle head 4, and holding the nozzle head 4. A peripheral wall 2d surrounding a stem 3f at a spaced interval, and making its lower end as the upper stopper of the piston 3d, in the attitude of the nozzle head 4 capable of being pushed in, is formed at the adapter 2, and the resilient member S for urging the nozzle head 4 upwards between the stem 3f and the peripheral wall 2d is arranged to bias upwards. <P>COPYRIGHT: (C)2012,JPO&INPIT |
