- a stirring ring 15 is movably arranged in a space 44 formed between the middle cylinder 94 and the front shaft 54.
- the stirring ring 15 is disposed so as to surround the middle cylinder 94. That is, by shaking the applicator up and down, the stirring ring 15 also moves up and down, whereby the liquid in the space 44 is also stirred.
- the example shown in FIG. 14 is an example in which the stirring ring 15 in the ninth embodiment is a sphere 16, which can freely move in the space 44, and has a more effective stirring effect than the previous example. It has been improved. ⁇ Eleventh embodiment>
- FIGS. 15 and 16 are longitudinal cross-sectional views of the essential parts showing the eleventh embodiment.
- This embodiment has the same configuration as that of the fourth embodiment, except that a flange portion 56 b inside the front shaft 56 is formed of a radial rib having a cross-sectional shape in the axial direction, and the center shaft 96 has The flange 96 d at the front of the large-diameter portion abuts so that the center shaft 96 can be positioned and fixed to the front shaft 56.
- the valve-equipped applicator of the present embodiment can reduce the thickness of the front shaft, and minimize dimensional variations due to sink marks and the like.
- the valve-equipped applicator according to the present invention includes a shaft cylinder having a coating liquid containing at least a pigment, a solvent, and a surfactant, and a stirrer that stirs the coating liquid, and serving as a coating liquid storage chamber.
- a front shaft having a coating mechanism having a valve mechanism formed thereon is fixed to a front opening of the front shaft so that the coating liquid storage chamber communicates with the space inside the front shaft.
- a valve-equipped applicator having a through-hole in between and a part of the through-hole having a small hole through which a coating liquid does not pass by natural fall, wherein a small hole is provided near the coating liquid storage chamber side of the small hole. Protrusions are provided to prevent the agitator from colliding with the parts. Thus, collision of the stirring body with the small hole of the middle cylinder can be prevented. Therefore, the small holes are not damaged or crushed, and the insoluble substance enters the front shaft and the application destination, and lowers the coating liquid, makes it impossible to discharge, and prevents outflow of the coating liquid. This makes it possible to prevent discharge from becoming impossible.
