Description

Applicator {APPLICATOR}

The present invention relates to an applicator for fixing an application material such as a porous core or an application core made of hardened fibers that can guide the application liquid through capillary action. will be.

In the applicator, the means for fixing the application core has conventionally been to provide a concave part in the application core, provide a convex part on the axis, and fit the convex part to the concave part, or to firmly tighten the application core. There was something to fix it.

In the former method of providing a concave portion in the coating core, the cross-sectional area of the coating core is reduced, and in the latter method of tightly tightening the coating core, the flow path is blocked due to tight tightening. However, there is a problem that smooth liquid feeding becomes difficult.

Therefore, in the applicator described in Patent Document 1, the above-mentioned problem is solved by fixing a plurality of application cores by driving pins into the resin line shaft. In the applicator described in this patent document 1, a plurality of application cores are arranged on the same plane by inserting and passing through an application core insertion hole formed in the line axis, and needle-shaped pins are driven into the line axis side. In this way, the plurality of application cores are fixed to the linear axis by sequentially passing identical pins through the plurality of application cores approximately perpendicular to the longitudinal direction.

However, the applicator of Patent Document 1 is difficult to manufacture because it is necessary to force the pin through the coating core of the resin molded product and drive the pin straight with high positioning accuracy. Specifically, if it cannot be driven in like that, the pin a will be driven in at a displacement with respect to the coating core b, as shown in Fig. 10 (a), so the coating core b can be driven into the line axis c. ) cannot be securely fixed. The misalignment that occurs at that time includes misalignment of the pin a due to positioning failure (represented by symbol "a1") and misalignment due to driving in at an angle (represented by symbol "a2"). In order to eliminate the misalignment, it was not possible for workers to assemble it by hand, so a dedicated facility was required, which hindered workability.

In addition, as shown in Figure 10 (b) near the pin hole, when the pin (a) is driven in, the application core (b) bulges, and the application core (b) caught between the pin (a) and the inner wall of the axis (c) Since the distribution path of the coating core (b) is limited to the portion (b1) of b), there is a problem that sufficient supply of the coating liquid is impeded.

In the present invention, the fixing force of the coated material in the groove is 10 N or more. More preferably, the holding force is 20N or more.

According to the applicator of the present invention, the fixing member is fixed to the core support while the protrusion of the fixing member is pierced into the applicator, thereby fixing the applicator to the core support, and in the fixed state of the applicator, Since the applicator is mounted on the line shaft, it can be easily positioned and fixed by fixing the fixing member to the core support compared to the conventional structure in which the applicator is fixed by driving a pin into it. In addition, compared to the method of piercing a protrusion into the coated material, the bulge of the coated material is less than in the method of penetrating a pin, so it is difficult to restrict the flow path of the coating liquid, and the flow path can be secured.

Therefore, it is possible to achieve the excellent effect of being able to provide an applicator that can easily fix the coating material and secure a flow path for the coating liquid.

In addition, if the fixing member and the core support have a structure in which a pin body is provided on one side and an attachment hole is provided on the other side, and the pin body is inserted into the attachment hole, thereby fixing the fixing member and the core support to each other, the pin body is inserted into the attachment hole. By inserting it into the , the fixing member can be fixed, making it easy to fix the coated body.

In addition, if the core support and the brush body are integrated, assembly efficiency can be improved.

Additionally, if the sum of the outer diameter of the coated material and the outer diameter of the projections is larger than the width between the grooves on the coated material side of the fixing member, the applied material bulges and fits tightly within the grooves, thereby improving the fixing force.

[Application unit (12)]

In the applicator according to the embodiment, as shown in FIG. 3, the applicator 12 having a plurality of coated bodies 10 is installed on the core support 16 in a row of the plurality of coated bodies 10. Then, the core support 16 is sandwiched between the two sides in the thickness direction by the fixing members 18, and the projections 14 are pierced and fixed to each coated body 10. FIG. 4 shows the assembly of the applicator 12, FIG. 5 shows the core support 16, FIG. 6 shows the fixing member 18, and each part diagram is shown. Figure 7 shows a parts diagram of the line shaft 28.

[Applying body (10)]

The coated body 10 has a rod shape, and the liquid holding power of the coated body 10 described in Japanese Patent No. 4726439 can be applied. As an example of the material of the coated body 10 of the embodiment, a sliver pen core, a felt-like material, an open-cell sponge-like material, etc. are preferable.

[Core support (16), fixing member (18)]

As shown in FIG. 5, the core support 16 has a thick plate-shaped main body 16b of a roughly rectangular shape with a plurality of plate-shaped combs 22 extending linearly. The central portion in the longitudinal direction of the main body 16b has a rectangular cross-section, and a plurality of insertion holes 16c are formed along the longitudinal direction. And at the rear portion of the main body 16b, a wall portion 16d is formed across a groove provided by cutting. The groove is continuous with the insertion hole 16c and has a bottom portion whose inner diameter is substantially the same as that of the insertion hole 16c. A through hole 16d2 that penetrates the front and back is formed at the bottom. In addition, an attachment hole 16d1 is formed through the wall portion 16d in the thickness direction of the core support 16 through which the guide pin 24 is inserted and passed. When viewed from the front, as shown in Fig. 5 (a), the insertion hole 16c is located between the bits 22, and when viewed from the rear, as shown in Fig. 5 (g), the insertion hole 16c is located in the wall portion. It is located between (16d, 16d).

As shown in FIG. 6, the fixing member 18 is provided with two guide pins 24 standing upright in a column shape from the main body 18a of a flat rectangular plate portion, and the projection 14 also protrudes and is formed as one piece. It is done. In addition, the main body of the fixing member 18 is formed with an insertion hole 18b into which the guide pin 24 of the opposite fixing member 18 is mounted. At the tip of the guide pin 24, a bulging neck 24a with a slightly larger diameter is formed to prevent it from falling out when inserted into the insertion hole 18b.

Additionally, the core support 16 and the fixing member 18 can be made of various resins (polypropylene, polyethylene, polybutylene terephthalate, etc.).

The applicator 12 is assembled by attaching a plurality of applicators 10 to the core support 16, as shown in FIG. 4 .

First, the coated material 10 is inserted into the insertion hole 16c of the core support 16 along the longitudinal direction (direction of arrow F). In this case, a plurality of coated bodies 10 are aligned in the thickness direction, and a plurality of coated bodies 10 are placed into the insertion hole 16c of the core support 16 in the column direction. Therefore, the core support 16 achieves the function of a jig for aligning and inserting the applied material 10.

Next, the fixing members 18 from the upper and lower sides are mounted on the core support 16 on which the coated material 10 is mounted so as to fit from both sides in the thickness direction (arrow G direction). By this mounting operation, the plurality of projections 14 of the fixing member 18 are respectively fixed to the plurality of coated bodies 10 from the radial direction, and the plurality of guide pins 24 of the fixing member 18 are fixed. is inserted into the plurality of mounting holes 16d1 of the core support 16 to attach and secure the fixing member 18 to the core support 16, and thus the applied body 10 is tightly fixed to the core support 16. I order it.

Then, the tip of the guide pin 24 is installed in the insertion hole 18b of the fixing member 18 on the opposite side (when mounting, it is mounted by pressing vertically with a toggle press, etc.). At this time, the bulge neck portion 24a of the guide pin 24 fits into the insertion hole 18b of the fixing member 18, thereby preventing it from falling out.

Therefore, the fixing member 18 functions as a fixture for the applied body 10.

In addition, as shown in FIG. 4, during assembly, the guide pin 24 is inserted into the mounting hole 16d1, so that the positioning of the fixing member 18 with respect to the core support 16 is accurate, and the protrusion Since (14) can be pressed into the width direction center of the coated body (10), it can be easily and precisely assembled.

The state in which the applicator 12 is assembled is as shown in FIG. 3 . The tip of the coated material 10 goes slightly inside the tip of the brush 22, so that the coated material 10 does not come into contact with the skin when applying.

Moreover, as shown in FIG. 4, the sum of the outer diameter ϕD of the coated body 10 and the outer diameter x of the projection 14 is equal to the spacing w2 (coated) between the wall portions 16d of the core support 16. It is set to be larger than the width of the groove on the sieve 10 side (D+x>w2).

As a result, the mounted coated material 10 expands within the groove, abuts against the inner wall of the wall portion 16d, and fits into the groove, thereby improving the fixing force of the coated material 10. do.

As explained above, according to the applicator of the embodiment, by attaching the fixing member 18 to the core support 16, the protrusion 14 is pierced into the applicator 10, and the application is applied to the core support 16. After fixing the sieve 10, the applicator 12 is mounted on the line shaft 28, as shown in FIG. 2.

Therefore, the applicator is easy to position compared to the conventional structure in which the applicator is fixed by inserting a pin into the applicator. Additionally, although the protrusion 14 is pierced into the coated body 10, compared to penetrating a pin, the coated body 10 does not bulge, so the flow path of the coating liquid is less likely to be restricted, and the flow path can be secured.

Therefore, it is possible to achieve the excellent effect of providing an applicator that can easily fix the coated body 10 and secure a flow path for the coated liquid.

In addition, since the core support 16 and the brush body 22 are integrated, assembly efficiency can be improved.

In addition, since the sum of the outer diameter D of the coated material 10 and the outer diameter ) is inserted to improve the fixing force.

Regarding the improvement of the fixing force of the coated body 10, the effect will be explained using a specific structure as an example. Regarding the core support 16 whose appearance is shown in Fig. 8 (a), a comparative example is shown in (b) and an example is shown in (c) with respect to cross sections along lines B, C-B, and C.

8(b) and 8(c) show comparative examples and examples where a coated body 10 of specific dimensions is fixed by the core support 16 and the fixing member 18 (by piercing the projection 14). It shows the bulging and fixed state of the coated body 10 when applied. 9 is an explanatory diagram of the pressure on the inner wall of the groove created by the coated body 10 during fixation in comparative examples and examples.

In the applicator (applicator) of the comparative example shown in FIG. 8 (b), the core support 16 has a groove width (between the walls 16d and 16d) W of 3.7 mm, depth H of 2.4 mm, and an application body ( The diameter ϕD of 10) was set to 2.55 mm, and the width x of the projection 14 was set to 0.8 mm.

As shown in Figure 8 (b), in the above comparative example, when the coated material 10 is pierced with the protrusion 14, the coated material 10 bulges 0.8 mm, which is x the width of the protrusion 14. It was almost 3.35 mm, as shown in the image shown by the dashed line. Since the width w1 of the groove was 3.7 mm, the coated material 10 did not contact the inner surfaces of the wall portions 16d and 16d of the groove, became loose, and the coated material 10 could not be tightly fixed.

In contrast, in the example shown in Fig. 8(c), the width w2 of the groove (between the wall portions 16d and 16d) in the core support 16 was w2 = 3.0 mm, unlike the comparative example. Otherwise, the depth H is 2.4 mm, the diameter phiD of the coated body 10 is 2.55 mm, and the width x of the projection 14 is 0.8 mm.

In the example, when the coated material 10 was pierced with the protrusion 14, the coated material 10 bulged by 0.8 mm, which is x the width of the protrusion 14, and was approximately 3.35 mm as shown in the image shown by the broken line. Since the width w2 of the groove was 3.0 mm, the coated material 10 came into contact with the inner surfaces of the wall portions 16d and 16d of the groove, and the coated material 10 was able to be firmly and tightly fixed.

For the above comparative examples and examples, the pressing force against the coated body 10 in the groove is shown in Fig. 9. Additionally, the dimensions of the protrusion 14 were 0.8 mm in width x, 1.5 mm in vertical length y, and 3.6 mm in length z in the protruding direction. In detail, the length z1 to the tip wedge portion is 2.9 mm, the length z2 of the wedge portion is 0.7 mm, the wedge-shaped angle θ is 59.5 degrees, and the tip width t = 0.5 mm.

As shown in Fig. 9, in the comparative example (see Fig. 8(b)), the groove width w1 was wide and was 3.7 mm, so the coated body 10 was not distorted and the fixing force was 9.5 N (Newton).

On the other hand, in the example (see Fig. 8(c)), the groove width w2 was 3.0 mm, so the amount of crushing of the coated body 10 was 0.35 mm, and the fixing force was 28 N (Newton).

From the above, it is understood that in the comparative example, the coated body could not be fixed because it was loose, but in the example, it could be strongly pressed and tightly fixed.

In addition, the embodiment is an example, and it goes without saying that various modifications can be made.

In the above embodiment, the coated materials 10 are arranged in four rows of two each, mounted on the core support 16, and provided in the applicator 12. However, the arrangement of the coated materials 10 in the applicator 12 is as follows. Of course, it is not limited to this. You may arrange one or more coated bodies, or you may provide the coated body on one side of the core support and fix it with a fixing member.

In addition, it is not limited to the applicator according to the above embodiment, and can be used for various applicators other than those for hair. In addition, the structure of the applicator, such as the structure of the applicator and the shape, material, number, and arrangement of the applicator, is not limited to the embodiment and can be modified in various ways.

The applicator of the present invention can be used in cosmetics such as a hair applicator, and can also be used in general writing instruments.
