DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an applicator in which an applicator holding a coating liquid by capillary force is covered with a cover having comb-shaped slits. Wearing and dyeing fibrous materials such as hair dyeing tools for hair, bleaching tools for stains and stains on carpets, etc.
Alternatively, those used for decolorization are suitable targets.

No. 1, JP 59-190101, JP 5
As described in JP-A-8-49319 and the like, applicators of the type described above are known. Since it can be applied by the applicator together with combing by the comb teeth forming the slit, it has an advantage that the application to hair and other fibrous bodies can be performed easily and quickly. Further, it has an advantage in terms of the drying resistance of the coated body as compared with the case without the coated body. That is, in a normal applicator without a cover,
If you do not use the product with the cap removed, the coating often dries out, and if you try to avoid this by increasing the amount of coating liquid that can be held on the coating, the coating often drops from the coating. It will be done,
In the above-described applicator, the coating body is difficult to dry because the coating body covers the coating body.

An object of the present invention is to improve the coating liquid dischargeability of the above-mentioned type of applicator having such advantages.

(Means for Solving the Problems) The present invention is an applicator in which an applicator that holds the application liquid by capillary force is covered with a cover having comb-teeth-shaped slits, and the comb-teeth that make up the slit are The gist is an applicator in which an outer wall portion that is curved and rounded serves as an application contact portion, and one end is a free end and the inner wall portion elastically abuts the application body.

(Operation) By the elastic deformation of the comb teeth of the covering body and the elastic deformation of the coating body, the coating liquid held in the coating body is squeezed out. At this time, the comb-teeth portion serving as the application contact portion smoothly contacts the contacted body, and damage of the contacted body is suppressed as much as possible.

(Embodiment) A first embodiment will be described with reference to the attached FIGS. 1 and 2.
The shaft cylinder 1 is a main part of the shaft body, and has a tip attached to the tip thereof. In addition, a coating liquid occlusion body 3 for holding the coating liquid by a capillary force, which is generally called “filling pad”, is housed inside.

The tip 2 forms a part of the shaft body together with the barrel 1, and has a front portion 4a protruding from the tip 2 and a rear portion 4b embedded in the front portion of the coating liquid occlusion body 3. 4 is inserted. The coating body 4 is made of a fiber converging body, a porous body having continuous ventilation holes, or the like, holds the coating liquid supplied from the coating liquid storage body 3 by a capillary force, and is elastically deformable.

Further, the tip 2 has a covering body 5 for covering the front portion 4a of the coating body 4 attached to the front end portion. The cover 5 is made of a synthetic resin such as polyethylene or polypropylene, and has a comb tooth-shaped slit portion 5a at its tip. Here, the comb teeth of the covering body 5 forming the slit portion 5a are not linear but curved, and the tip of the applicator body 4 partially exposed from the slit portion 5a on the inner wall portion of the comb teeth. The part 4c is in contact. Further, the comb tooth has a rounded outer wall portion, and one end (upper end portion in the drawing) is a free end and is elastically deformable. Therefore, when the application pressure is applied to the outer wall portion of the comb tooth during use, the comb tooth elastically deforms, whereby the application body 4 also elastically deforms, and the application liquid held by the application body 4 is squeezed out.
The reference numeral 5b indicates a cutout portion.

Next, a second embodiment will be described with reference to FIG. The coating body 4 in this example is the slit portion 5 of the coating body 5.
A part is located in each slit of a. The tip portion 4c of the applicator body 4 receives the compressive force even in the non-use state, so that the slit portion 5a of the applicator body 4 and the cover body 5 can be obtained.
The contact with the inner wall portion of the comb teeth constituting the above is also good. The applicator 4 is illustrated with urethane in mind.

Next, a third embodiment will be described with reference to FIG. The cover 5 in the present example has comb teeth forming the slit portion 5 whose free ends are alternately located at the top and bottom of the drawing. As a result, gripping symmetry in use can be imparted.

Next, a fourth embodiment will be described with reference to FIGS. This example shows an example in which the entire structure can be appropriately adjusted, and this example has a valve structure in which the inside of the barrel 1 serves as a tank 6 for containing the coating liquid.

The plate rod 9 is mounted on the tip of the valve rod 8 which is biased forward by the spring 7. The plate 9 extends forward through the center of the applicator 4 made of urethane or the like, and the positioning is made by contact with the rear end 5c of the cover 5. That is, the plate body 9 serves as a push plate for inserting the soft coating body 4 into the coating body 5, facilitating the mounting, and
It also serves as a support for the cover 5. Furthermore, the covering 5 is
It is slidable with respect to the tip 2. Therefore, when the cover body 5 is pressed, a force is transmitted to the rod body 8 through the plate body 9 and the rod body 8 retreats against the resilient force of the spring 7. That opens the valve. At this time, the comb-teeth portion of the covering body 5 is elastically deformed and the application liquid held in the applying body 4 is squeezed out.
It is similar to that described above. Reference numeral 2a in FIGS. 5 and 6 indicates a ridge formed on the inner side wall of the chip 2 in order to reduce sliding backlash of the covering body 5, and reference numeral 5d in FIG. A locking projection for the chip 2 formed so that the cover 5 does not fall off the chip 2 is shown. Reference numeral 2b in FIG. 5 is a locking wall for the locking projection 2b.

Although not shown, various other than the above, can be made. For example, the application body 4 may be formed of a plurality of members, such as a molded body having a communicating porous elastic body and a coating liquid conducting path arranged behind the communication porous elastic body. Further, for example, in FIG. 5, the rear portion of the applicator body 4 is enlarged and freely extends rearward so that the coating liquid discharged by opening the valve is temporarily stored. The coating liquid reservoir member which is not so large can be used as a separate body, and the valve structure can be a so-called rear end knock type. In addition, the coating body 4 illustrated as having a rectangular cross section may have a flat elliptical cross section, or the tip 2 and the barrel 1 in the fourth embodiment described above may be attached by screwing. For example, the appropriate member may have an appropriate shape and an appropriate attachment structure.

(Effects of the Invention) The applicator of the present invention is an applicator in which an applicator that holds the application liquid by capillary force is covered with a cover having comb-teeth-shaped slits, and the comb-teeth that form the slit are The curved and rounded outer wall portion serves as a coating contact portion, and the inner wall portion elastically abuts against the coating body with one end as a free end, so that the outer wall portion of the comb tooth is used during use. When the application pressure is applied to the comb teeth, the comb teeth are elastically deformed, whereby the application body is also elastically deformed, and the application liquid held by the application body can be squeezed out. Therefore, the dischargeability of the application liquid is excellent. Here, depending on the type of the coating liquid, there are many cases where the coating liquid component forms a film on the surface of the coating body due to drying, but the elastic deformation of the comb teeth causes the coating liquid to form a film on the surface of the coating body. Since the components are destroyed and a new coating liquid can be discharged, the discharging property of the coating liquid is excellent also in this respect. In addition, in use, it is common to directly contact the portion of the comb tooth, which is the coating contact portion, with the object to be coated, such as the head or carpet, for simple operation. Since the outer wall portions of the teeth come into smooth contact with the object to be coated, damage to the object to be coated can be suppressed as much as possible.
