[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 11, an applicator for applying a cosmetic agent such as lip gloss, eye shadow, or nail polish to a predetermined portion has been generally widely used. In FIG. 11, R has a total length of 3 cm to
It is a rod made of synthetic resin set to about 6 cm, and a brush head H (tip) on which flock f made of short fiber synthetic polymer is planted is provided at the tip thereof.

As shown in FIG. 12, the rod R is a hollow shaft, while the brush head H has a mandrel e whose one end is inserted into the tip of the rod R and a flock f which is adhered to the outer circumference of the other end of the mandrel. Composed of. The mandrel e is a short shaft mainly made of synthetic resin, and an adhesive is applied to the outer periphery of one end of the mandrel e, and then a flock f is fixed to the applied portion by a flocking machine (flocking machine).

Although the flock f is attached to the adhesive application portion by utilizing static electricity, it may be sprayed on the adhesive application portion by vibration or sprayed with a spray gun.

In the brush head H of that kind, after flocking, one end of the mandrel e is inserted into the tip of the rod R and fixed with an adhesive. As shown in FIG. 13, a wire may be used for the mandrel e as the brush head H, but the mandrel e also made of wire is inserted into the tip of the rod and fixed by an adhesive or heat welding.

[0006]

However, in the conventional makeup applicator as described above, the rod and the brush head, which are individually made, are combined, so that the number of working steps and materials used are large and the cost is high. Since the head is a small component with a total length of less than a few centimeters, it was very cumbersome and time-consuming to attach it to the rods one by one.

Further, when the brush head is attached to the rod, a fixing adhesive adheres to the flock to solidify the fibers into a bundle, or the brush head falls off due to lack of the adhesive. was there. Furthermore, when fixing the flock to the mandrel, the adhesive applied to the mandrel may flow and the flock may not adhere evenly, resulting in uneven fur.

The present invention has been made in view of the above circumstances, and its purpose is to manufacture a high-quality makeup applicator with a uniform coat and to efficiently manufacture it at a low defect rate and at low cost. To provide a method.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, application examples of the present invention will be described in detail with reference to the drawings. First, FIG. 1 shows a side view of a makeup applicator according to a preferred embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a round shaft-shaped rod having a total length set to about 3 to 8 cm. This rod 1 is made of, for example, polybutylene terephthalate (PBT) or polypropylene (PBT).
P), polystyrene (PS), polyethylene terephthalate (PET), or synthetic resin such as acrylonitrile butadiene styrene resin (ABS).

A cylindrical grip portion 2 having a diameter larger than that of the rod 1 is integrally formed at one end portion of the rod 1, and the tip end outer periphery on the opposite side has a length of 1 cm to several cm. Flock 3
Is provided with a flocked part 4 which is directly bonded.

The grip portion 2 is a portion to be a knob when applying a cosmetic agent, and the length thereof is set to about several cm, but it is used for a liquid cosmetic agent such as nail polish and the grip portion 2 is used. A screw-type cap that covers the mouth of a container filled with such a cosmetic agent is integrally fixed to the.

On the other hand, the flock 3 forming the bristle portion 4 is
A short fiber having a fiber diameter of several μm to several tens of μm and a fiber length of 0.1 mm to several mm, which is mainly composed of a polyamide-based synthetic polymer such as nylon, rayon, acrylic, aramid, or polyethylene. In addition to plant fibers such as cotton, animal fibers can also be used.

Next, FIG. 2 is an enlarged view showing the tip of the rod, and FIG. 3 shows a cross section taken along line XX in FIG.
As is apparent from these figures, in this example, the outer periphery of the tip end portion of the rod 1 is a spline shape as the fixing region of the flock 3. 5 is a width of 0.1 mm extending along the axial direction of the rod 1.
It is a ridge of about 0.5 mm, which is 90 in this example.
Depth is 0.1 mm between each of the ridges 5.
Groove-shaped recesses 6 of about 0.5 mm are formed at equal intervals.

The concave portion 6 is a portion on which an adhesive for fixing the flock 3 is placed, and the elongated ridges 5 sandwiching this are provided.
Serves to prevent the adhesive in the recess 6 from flowing in the circumferential direction and locally concentrating. Then, the rod 1 in which the concave portion 6 is filled with the adhesive is sent to a flocking step and subjected to flocking.

The manufacturing method will be described in detail below.
As shown in FIG. 4, such an applicator generally starts with application of an adhesive to the tip of the rod, undergoes a flocking step, a drying step, and a static elimination step, and is finally finished by blowing dust in an air blowing step.

First, the rod 1 is set in a jig (not shown), and the tip of the rod 1 is immersed in an adhesive tank (not shown) by the operation of the jig. As a result, the tip of the rod 1 is filled with the adhesive 7 in the recess 6 as shown in FIG. The adhesive 7 is chloropyrene-based, nitrile rubber-based,
It is made of urethane type, epoxy type, cyanoacrylate type, silicone type, or the like, and is stored in an appropriate amount in an adhesive agent tank (not shown).

Next, as shown in FIG. 6, the rod 1 to which the adhesive 7 is applied is sandwiched between the conveyors 8A and 8B and sent to the flocking step, and a flock is adhered and fixed to the outer periphery of the tip end portion. . Although a known flocking machine 9 can be used in the hair transplanting step, it is preferable to rotate the rod 1 fed thereinto around the axis. In order to rotate the rod 1, it is conceivable to make the traveling speeds of the upper conveyor 8A and the lower conveyor 8B different, but a dedicated jig device may be used for this.

According to this, since the rod 1 passes through the flying region of the flock to which the electrostatic force is applied while rotating, and the adhesive 7 attached to the tip of the rod 1 is kept immovable in the recess 6. The flock 3 is evenly attached to the outer periphery of the tip end portion of the rod 1 by the adhesive 7 in the recess 6 so as to be fixed.

Thus, the rod 1 which has undergone the hair transplanting step is continuously flown to the drying step, where the adhesive 7 in the concave portion 6 is heated and dried, and then the static electricity charged on the floc 3 is removed by the usual method in the static elimination step. After the removal, air is blown to the flocked portion 4 in the air blowing step to remove flock debris and other dusts, thereby obtaining a makeup applicator as shown in FIG.

A preferred example of the present invention has been described in detail above with reference to the drawings. However, the present invention is not limited to the above example. In addition to the fine groove-shaped concave portions, this may be formed in a mesh shape or may be formed as a plurality of hole groups. Further, this may be a spiral groove as shown in FIG. 7, or an annular groove centered on the axis of the rod 1 as shown in FIG.

Further, as shown in FIG. 9, the rod 1 is provided with a step 10 having a small diameter at its tip, and an adhesive 7 is attached to the tip having a small diameter. The flock 3 may be fixed. According to this, since the adhesive 7 attached to the tip portion is prevented from flowing to the other end side by the step 10, the flock 3 can be fixed only to the tip portion, but the tip having a small diameter is also used in this example. It is more preferable to previously form a concave portion in the portion.

Further, as shown in FIG. 10, an annular groove 11 is formed on the rod 1 as a boundary of the tip portion, and the adhesive 7 is applied to the tip portion divided by the annular groove 11, and then a flock is applied to the application portion. The flock 3 may be fixed by a processing machine or the like. According to this, since the adhesive 7 attached to the tip portion is prevented from flowing to the other end side by the annular groove 11, the floc 3 can be fixed only to the tip portion. It is more preferable to form a concave portion in advance at the tip portion divided by 11.

On the other hand, in the step of applying the adhesive, the rod 1
In addition to immersing the tip portion of the above into the adhesive tank, the tip portion may be passed between a pair of gluing rollers.

In the flocking step, the floc 3 is attached to the outer periphery of the tip of the rod 1 by electrostatic force as in the above example, and the tip of the rod 1 coated with the adhesive 7 is placed on the deposition layer of the floc 3. It is also possible to roll it with, or sprinkle the floc 3 on the tip of the rod 1, or spray it with a spray gun.

[0028]

As is clear from the above description, according to the present invention, since the flocs are directly adhered to the outer circumference of the tip portion of the rod, it is more troublesome than the conventional one in which a minute brush head is attached later. Since fine work is not required, workability is greatly improved, production efficiency can be greatly improved, and since the mandrel for the brush head and the adhesive for fixing this to the rod as in the past are not required, Material costs can be significantly reduced, and since no adhesive is used after flocking, there is no risk of it adhering to the flock and binding the fibers together.

By forming a step or an annular groove in the rod that divides the tip of the rod, it is possible to prevent the adhesive applied to the tip of the rod from flowing to the other end, so that the floc is formed only in the tip. Can be properly fixed.

In particular, since the recess is formed on the outer periphery of the tip of the rod and the adhesive for fixing the flock is filled in the recess, the adhesive is locally applied until the flock is fixed. It can be fixed in the recess so that it does not concentrate, and the flock can be fixed evenly, and the root of the flock can be made larger by the depth of the recess, so the floc is hard to come off, and the adhesive will set in the recess. The flocs do not come off together with the adhesive during use.
