Description

  The present invention relates to an applicator in which an application body such as a porous core capable of inducing a coating liquid by capillary action or an application core obtained by solidifying fibers is fixed.

  In the applicator, conventionally, the application core fixing means has been provided with a concave portion on the application core, a convex portion on the front shaft, and the convex portion is fitted into the concave portion, or the application core is fastened and fixed.

  When the concave portion is provided in the coating core as in the former, the cross-sectional area of the coating core is reduced, and when the coating core is tightened as in the latter, the flow path is blocked by tightening, and smooth liquid feeding is difficult in both cases. There is a problem to become.

  Therefore, in the applicator described in Patent Document 1, a plurality of application cores are fixed by driving a pin onto a resin tip. The applicator described in Patent Document 1 is inserted through a coating core insertion hole formed in the tip shaft, and a plurality of coating cores are arranged on the same plane, and a needle-like pin is driven into the side surface of the tip shaft. In this structure, the plurality of coating cores are fixed to the front shaft by passing a series of identical pins substantially perpendicular to the longitudinal direction of the plurality of coating cores.

  However, the applicator of Patent Document 1 is difficult to manufacture because the pin penetrates the coating core of the resin molded product, and therefore it is necessary to drive the pin vigorously and increase the positioning accuracy to drive the pin straight. . Specifically, when such driving cannot be performed, the pin a is displaced with respect to the coating core b as shown in FIG. Cannot be fixed. The displacement that occurs at that time includes a displacement of the pin a due to positioning failure (indicated by the symbol “a1”) and a displacement due to oblique driving (indicated by the symbol “a2”). In order to eliminate the deviation, the operator cannot cope with manual assembly (manual assembly), so that a dedicated facility is necessary, which hinders workability.

  Further, in the vicinity of the pin hole, as shown in FIG. 11B, the coating core b swells when the pin a is driven, and the coating core b is a portion b1 of the coating core b sandwiched between the pin a and the inner wall of the front shaft c. Since the flow path of b is limited, there is a problem that the supply of the coating solution is hindered.

In the present invention, the fixing member is provided with a main body, a lid, and a bending hinge that connects the main body and the lid.
It is preferable that the fixing member be fixed by sandwiching the application body between the main body and the lid portion in a state where the fixing member is bent from the hinge.

  In the present invention, the main body or the lid portion is provided with positioning means for positioning the main body and the lid portion in the facing surface direction when the applicator is sandwiched and fixed by the main body and the lid portion. It is suitable.

  In the present invention, it is preferable that a space is provided in an opposing portion of the protrusion inside the fixed member in the bent state.

  According to the applicator of the present invention, a fixing member having a protrusion and capable of being bent is provided, and by bending the fixing member, the protrusion is pierced into the application body to form an application portion in which the application body is fixed to the fixing member. Therefore, the positioning is easy as compared with the conventional structure in which the pin is driven and fixed to the application body. Further, although the protrusion is pierced into the application body, the application body does not swell compared to the case where the pin is penetrated, so that the flow path of the application liquid is less likely to occur, and the flow path can be secured.

  Therefore, it is possible to provide an applicator that can easily fix the application body and can secure a flow path for the application liquid.

  In addition, since a space is provided in the opposed part of the protrusion inside the fixed member in the bent state, even if the application body stabbed by the protrusion swells, the space in the opposed part is escaped. It can produce excellent effects such as not causing

  Next, Examples 1 to 3 in which the application portion according to the embodiment has various protrusion shapes will be described in comparison with existing products.

  As shown in FIG. 9, Examples 1 to 3 (shapes 1 to 3) were compared with conventional examples (existing products 1 and 2) fixed with pins.

  As comparative conditions, Examples 1 to 3 and existing products confirmed the influence on the coating amount because the core coated body was deformed and fixed.

The coating amount evaluation method was recorded on an industrial paper waste (manufactured by Nippon Paper Crecia Co., Ltd .: 12 plies of 12 plies) and the amount of liquid discharged (liquid consumption) for 10 seconds was recorded (each n = 1, comb was Leave it out). The coating liquid used is an acidic hair dye having a viscosity of 3.4 mPa · s at 25 ° C. with an ELD viscometer (manufactured by Toki Sangyo Co., Ltd.) and a pH of 2.9 measured by a glass electrode pH meter in a conventional manner. The formulation was as follows.
Water-soluble dye Orange No. 205 0.5% by weight
Water-soluble dye Red 227 0.5% by weight
Amphoteric acrylic resin 0.3 wt% (solid content conversion)
Benzyl alcohol 10% by weight
Glycolic acid 5% by weight
Ethyl alcohol 54.7% by weight
Purified water balance

  As shown in FIG. 10 (a), the recorded results show that in Examples 1 to 3, the coating amount per core is 0.0225 to 0.0250 g, whereas in the existing product, 0.0175 to 0.005. 0180 g, and it was confirmed that the application amount of the example product was 20% or more of the existing product.

  Moreover, the drop test of Example goods 1-3 and the existing goods was implemented.

  The misalignment was confirmed when the product was turned upward and dropped onto the concrete floor in the order of 1 m → 1.2 m → 1.5 m → 1.5 m.

The recording result is as shown in FIG.
Example 1 (Shape 1) was the least misaligned.
In practical use, it can be said that Example 1 and Example 2 have a sufficient core fixing force.

Since the applicator is formed with the applicator 12 to which the applicator 10 is fixed, the applicator 12 having the applicator 10 fixed to the fixing member 16 is formed by piercing the applicator 10 with the protrusion 14. As compared with a structure in which a pin is driven and fixed to a simple applied body, positioning is easy. Further, although the protrusion 14 is pierced into the application body, the application body does not swell compared to the case where the pin is penetrated, and therefore, the flow path of the application liquid is not easily restricted, and the flow path can be secured.

  Therefore, it is possible to provide an applicator that can easily fix the application body 10 and can secure and fix the flow path of the application liquid.

  In addition, since the space 32 is provided in the facing portion of the projection 14 inside the fixed member 16 in the bent state, even if the application body 10 stabbed by the projection 14 swells, the space 32 of the facing portion is allowed to escape. Therefore, a sufficient liquid flow rate can be secured because the flow path is not restricted.

  In addition, this invention is not limited to the applicator which concerns on the said embodiment, It can use for various applicators other than for hair. Moreover, the structure of the applicator and the configuration of the applicator, such as the shape, material, number, and arrangement of the applicator, are not limited to the embodiments, and can be variously modified within the scope of the present invention.
