Description

Applicator

The present invention relates to an applicator, which fixes an applicator such as a smear core formed by curing a porous core and fibers that can be induced by capillary action to induce a smear liquid.

In the applicator, the conventional means for fixing the applicator core is to provide a concave portion on the applicator core, provide a convex portion on the front axle, fit the convex portion into the concave portion, or fasten the applicator core tightly.

In the former, the cross-sectional area of the applicator core is reduced because the applicator core is provided with a recess, and in the latter case, the applicator core is tightened and the flow path is blocked due to the tightening, which has the problem that the liquid cannot be fed smoothly.

Therefore, in the applicator of Patent Document 1, the above-mentioned problem is solved by fixing a plurality of applicator cores and pins into a resin-made front axle. The applicator described in Patent Document 1 inserts a plurality of applicator cores on the same plane through an applicator core insertion hole formed in the front axle, and drives a needle-shaped pin into the side of the front axle to move toward it. A structure in which the same pin is continuously penetrated through the plural coating cores substantially perpendicular to the longitudinal direction, and the aforementioned plural coating cores are fixed to the front axle.

However, in the applicator of Patent Document 1, in order to penetrate the pin through the coating core of the resin molded product quickly and forcefully, and to improve the positioning accuracy, it is necessary to drive the pin straightly, which is difficult to manufacture. Specifically, when such driving is not possible, as shown in Fig. 10(a), the pin a is driven away from the coating core b, and therefore the coating core b cannot be reliably fixed to the front shaft c. The deviations that occurred at that time included the deviation of pin a caused by positioning failure (shown by the symbol "a1") and the deviation caused by tilting (shown by the symbol "a2"). In order to eliminate the deviation, since the operator cannot handle it by hand installation (assembly by manual operation), special equipment is necessary, which hinders workability.

In the vicinity of the pin hole, as shown in Figure 10(b), when the pin a is driven in, the smear core b will swell, and the portion b1 of the smear core b pinched by the inner wall of the pin a and the front shaft c will restrict it. The flow path of the smear core b has a problem of preventing sufficient supply of the smear liquid.

In the present invention, the fixing force is 10N or more. More preferably, the fixing force is 20N or more.

According to the applicator of the present invention, since the protrusion of the fixing member is pierced into the applicator body, the fixing member is fixed The applicator is fixed to the core base, and the applicator is fixed to the core base. In the fixed state of the applicator, the applicator is installed on the front axle, so it is fixed with the conventional applicator by driving a pin into it. In comparison, the fixing member can be easily positioned and fixed by fixing the fixing member to the core base. In addition, compared to a case where the application body is penetrated by a pin when the protrusion is inserted into the application body, since the application body has less swelling, the flow path restriction of the application liquid is less likely to occur, and the flow path can be ensured.

Therefore, the application body can be easily fixed, and an excellent effect of providing an application tool that secures the flow path of the application liquid can be achieved.

In addition, the fixing member and the core pedestal have a structure in which a pin body is provided on one side and a mounting hole is provided on the other side. The fixing member and the core pedestal are fixed to each other by inserting the pin body into the mounting hole. The fixing member can be fixed by inserting the body into the mounting hole, and the fixing of the applicator body becomes easy.

In addition, if the core base and the comb are integrated, the assembly can be more efficient.

In addition, if the total outer diameter of the applicator body and the outer diameter of the protrusion is larger than the width of the groove on the applicator side of the fixing member, the applicator body expands and fits tightly in the groove to improve the fixing force.

[Core pedestal 16, fixing member 20]

As shown in Fig. 5, the core base 16 has a plurality of plate-shaped comb-shaped bodies 22 extending forward from a substantially rectangular thick plate-shaped main body 16b. The central part 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. In the rear portion of the main body 16b, a wall portion 16d is formed so as to sandwich the cut groove. This groove is continuous with the aforementioned insertion hole 16c and has a bottom having almost the same inner diameter as the insertion hole 16c. A through hole 16d2 penetrating the front and back is formed at the bottom. In addition, in the wall portion 16d, a mounting hole 16d1 for inserting the guide pin 24 in the thickness direction of the core base 16 is formed to penetrate in the thickness direction. Viewed from the front, as shown in Figure 5(a), the insertion hole 16c is located between the comb-shaped bodies 22, and viewed from the rear, as shown in Figure (g), the insertion hole 16c is located A position pinched by the walls 16d and 16d.

As shown in FIG. 6, the fixing member 18 has two guide pins 24 standing upright from a main body 18a of a flat rectangular plate portion in a columnar shape, and a protrusion 14 is also integrally formed so as to protrude. In addition, the main body 18a has an insertion hole 18b provided with the guide pin 24 of the fixing member 18 on the opposite side. In the tip portion of the guide pin 24, a bulging portion 24a with a few large diameters is formed in order to prevent slippage when the guide pin 24 is inserted into the insertion hole 18b.

In addition, various resins (polypropylene, polyethylene, polybutylene terephthalate, etc.) can be used for the material of the core base 16 and the fixing member 18.

The application part 12 is assembled by mounting the plural application bodies 10 on the core base 16 as shown in FIG. 4.

First, the applicator 10 is inserted into the insertion hole 16c of the core base 16 along the longitudinal direction (arrow F direction). In this case, the plurality of smear bodies 10 are aligned in the thickness direction, and the plurality of smear bodies 10 are inserted into the insertion holes 16c of the core base 16 in the column direction. Therefore, the core base 16 can achieve the function of a jig in which the applicator 10 is placed in a row.

Next, the fixing members 18 are mounted on the core base 16 separately from the top and bottom so as to be pinched from both sides in the thickness direction (arrow G direction) of the core base 16 on which the applicator 10 is installed. By this mounting action, the plural protrusions 14 of the fixing member 18 are respectively pierced into the plural applicator bodies 10 from the radial direction to be fixed, and the plural guide pins 24 of the fixing member 18 are inserted into the plural mounting holes of the core base 16 16d1 installs and fixes the fixing member 18 on the core base 6, so the applicator 10 is tightly fixed to the core base 16.

In addition, the tip of the guide pin 24 is installed in the insertion hole 18b of the fixing member 18 on the opposite side (when installed, it is installed vertically by a toggle press or the like). At this time, the bulging portion 24a of the aforementioned guide pin 24 is inserted into the insertion hole 18b of the fixing member 18, and is prevented from falling out.

Therefore, the fixing member 18 can fulfill the function of a fixing device of the applicator body 10.

And as shown in Fig. 4, during assembly, the guide pin 24 is inserted into the mounting hole 16d1, so the positioning of the fixing member 18 of the core base 16 becomes correct, and the protrusion 14 is inserted into the width direction of the applicator 10 Center, so it can be easily assembled with high precision.

The state in which the application part 12 is assembled is as shown in FIG. 3. The tip of the smear body 10 is more retracted than the tip of the comb body 22, and the smear body 10 will not come into contact with the skin during smearing.

And as shown in Fig. 4, the total of the outer diameter (ΦD) of the applicator body 10 and the outer diameter (x) of the protrusion 14 is greater than the distance w2 between the wall portions 16d of the core base 16 (on the applicator body 10 side). The width of the groove) is larger (D+x>w2).

As a result, the installed applicator 10 is inserted into the groove by expanding the applicator 10 in the groove so as to abut against the inner wall of the wall portion 16d, so that the fixing force of the applicator 10 can be improved.

As explained above, according to the applicator of the embodiment, by installing the fixing member 18 on the core base 16, the protrusion 14 is pierced into the applicator 10, and the applicator 10 is fixed behind the core base 16, as As shown in FIG. 2, the application part 12 is installed on the front axle 28.

Therefore, the applicator is easier to position than the conventional structure in which the pin is driven into the applicator body to be fixed. In addition, compared with a penetrating pin in which the protrusion 14 is pierced into the application body 10, since the application body 10 does not swell, restriction of the flow path of the coating liquid is less likely to occur, and the flow path can be secured.

Therefore, the application body 10 can be easily fixed, and an excellent effect of providing an application tool that secures the flow path of the application liquid can be achieved.

In addition, since the core base 16 and the comb body 22 are integrated, the assembly can be made more efficient.

Moreover, the total of the outer diameter D of the applicator body 10 and the outer diameter x of the protrusion 14 is larger than the width w2 between the grooves on the applicator body 10 side of the core base 16, so in the groove, the fixing force of the applicator body 10 is Can be improved.

Regarding the improvement of the fixing force of the smear body 10, a specific structure is taken as an example to illustrate the effect. For the core pedestal 16 whose appearance is shown in Fig. 8(a), the comparative example is shown in (b) and the embodiment is shown in (c) according to the cross-sections of the lines B, C-B, and C.

Figure 8 (b) and (c) show the application body 10 when the application body 10 of specific size is fixed by the core base 16 and the fixing member 18 (the protrusion 14 is inserted) for the comparative example and the embodiment. The bulging and fixed condition. In addition, Fig. 9 is an explanatory diagram of the pressure against the inner wall of the groove generated by the applicator 10 during the fixation of the comparative example and the embodiment.

In the applicator (applicator section) of the comparative example shown in Figure 8(b), the core base 16 has the width of the groove (between the wall sections 16d and 16d) W set to 3.7 mm and the depth H set to 2.4 mm , The diameter ΦD of the applicator 10 is set to 2.55 mm, and the width x of the protrusion 14 is set to 0.8 mm.

As shown in Fig. 8(b), when the applicator 10 is pierced by the protrusion 14 in the above-mentioned comparative example, the applicator 10 is 0.8 mm of the width x min of the protrusion 14 and the image shown by the dotted line is almost It is 3.35mm. Since the width w1 of the groove is 3.7 mm, the applicator 10 does not abut the inner surfaces of the wall portions 16d and 16d of the groove, but is loosened, and the applicator 10 cannot be tightly fixed.

In this regard, in the embodiment shown in Fig. 8(c), the width w2 of the groove (between the wall portions 16d and 16d) in the core base 16 is different from the comparative example by the width w2=3.0 mm. Otherwise, the depth H is 2.4 mm, the diameter ΦD of the application body 10 is 2.55 mm, and the width x of the protrusion 14 is 0.8 mm.

In the embodiment, when the protrusion 14 penetrates into the smear body 10, the smear body 10 is 0.8 mm of the width x min of the expansion of the protrusion 14, and the image shown by the dotted line is almost 3.35 mm. Since the width w2 of the groove is 3.0 mm, the smear body 10 abuts on the inner surfaces of the wall portions 16d and 16d of the groove, and the smear body 10 is tightly fixed.

Regarding the above-mentioned comparative examples and examples, the pressing force of the smear body 10 in the groove is as shown in FIG. 9. In addition, the dimensions of the protrusion 14 are such that the width x is 0.8 mm, the longitudinal length y is 1.5 mm, and the length z in the protruding direction is 3.6 mm. 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°, and the tip width t=0.5 mm.

As shown in Fig. 9, in the comparative example (refer to Fig. 8(b)), since the groove width w1 is wide (wide) 3.7 mm, the application body 10 is not crushed, and the fixing force is 9.5 N (Newton).

Regarding this, in the embodiment (refer to FIG. 8(c)), since the groove width w2 is 3.0 mm, the crushing amount of the applicator 10 is 0.35 mm, and the fixing force is 28 N (Newton).

It can be understood from the above that although the application body cannot be fixed due to slack in the comparative example, it can be pressed strongly and can be tightly fixed in the example.

In addition, the embodiment is only an example, and of course various modifications can be implemented.

In the foregoing embodiment, the applicator body 10 is installed in the core base 16 in the form of two and four rows in the applicator section 12, but the arrangement state of the applicator body 10 of the applicator section 12 is of course not limited to this. Arrange 1 or multiple Several applicator bodies may be used, and the applicator body may be provided on one side of the core base and fixed by a fixing member.

It is not limited to the applicator of the foregoing embodiment, and various applicators other than hair use can be used. In addition, the structure of the applicator and the structure of the applicator such as the shape, material, number, and arrangement of the applicator are not limited to the examples, and various modifications can be implemented.
