doing. Therefore, in this state, the pump knob 2 is erroneously
Even if 1 is pressed, the pump device 2 does not operate. On the other hand, when using this liquid applicator, for example, to apply a coating liquid to a window glass of an automobile, as shown in FIG. 4, the upper side 4a of the coating portion 4 is pressed against the window glass G to make a stopper device 8 Then, the pump knob 21 is pushed down a proper number of times to drive the pump device 2. Then, the pressurized air from the pump device 2 is supplied to the container body 6.
The coating liquid W is blown into the inside of the container body 6 and is discharged from the discharge port 33a through the series of liquid discharge passages 3 (reference numeral Wa). The discharged coating liquid Wa successively permeates into the felt material 41, and after the felt material 41 is in a proper wet state, the window glass G is rubbed with the felt material 41, whereby the window glass G The coating solution can be applied to the. Further, when the amount of the coating liquid impregnated in the felt material 41 decreases, the pump knob 21 may be pressed while the upper end portion 4a of the coating portion 4 is pressed again (the stopper device 8 is unlocked).

Further, since the liquid applicator of this embodiment has the cover 5, as shown in FIG.
After covering one portion with the tissue paper T, the remaining portion of the tissue paper T can be sandwiched between the cover 5 and the applicator body 1 for use. Since the tissue paper has a high water absorption rate, the coating liquid of the felt material 41 portion immediately penetrates into the tissue paper. When the front surface of the felt material 41 is covered with the tissue paper T as described above, the application liquid in the felt material 41 can be applied to the window glass G through the tissue paper T, and the window glass is dirty. However, since the dirt can be wiped off with a tissue paper, the felt material 41 does not become dirty for a long period of time. If the tissue paper becomes dirty, it can be replaced with a new one.

[0028]

According to the liquid applicator of the present invention, the pump device 2 can be driven because the stopper device 8 functions even if the pump knob 21 is accidentally pressed when not actually used. Therefore, the coating liquid W in the container body 6 will not be accidentally discharged. Accordingly, the pump device 2 can be driven to supply the coating liquid to the coating part 4 (felt material 41) only when the user intentionally operates (with the intention of using), and the careless liquid can be supplied from the coating part 4. There is an effect that the drool can be prevented and the coating liquid is not wasted because the liquid does not drip.

When the liquid coating device is used to coat the coating liquid on the surface (window glass) G to be coated, the upper side 4a of the coating section 4 is placed on the surface G to be coated. After pressing the pump knob 21 in the pressed state, the coating part 4 (felt material 41) can be slid on the surface G to be coated as it is, and even if the stopper device 8 is provided, it is possible to perform the liquid discharging operation. Since the coating work can be continuously performed, there is also an effect that the coating work can be simplified.
