DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a cosmetic applicator used for applying cosmetics.

[0002]

2. Description of the Related Art Conventionally, when a cosmetic applicator such as a sponge puff used for applying cosmetics is manufactured, for example, FIG.
As shown in FIG. 1, first, an application part constituent member such as an NR foam is punched into a cylindrical plate shape, and an adhesive 110 is applied around a side surface of the cylindrical plate member 100. And adhesive 1
At this time, the upper and lower peripheral portions of the side surface of the cylindrical plate-shaped member 100 to which the ribbon 10 is attached are bonded together (at this time, the ribbon 1 is attached).
20 is sandwiched simultaneously around a part of the side surface) to manufacture a disc-shaped cosmetic applicator 130 with a ribbon having a rounded side surface.

[0003]

However, in the conventional manufacturing method as described above, since the process of bonding around the side required for attaching the ribbon is performed manually, it takes a long time to manufacture, and the manufacturing efficiency is increased. There was a problem that was bad.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method of manufacturing a cosmetic applicator capable of improving the manufacturing efficiency of a cosmetic applicator such as a sponge puff. And

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a cutting step for making a cut around the side of a plate-like member serving as an application section, and applying a heat to the cut formed by the cutting step. A heat welding material inserting step of inserting a welding material, a ribbon sandwiching step of sandwiching a ribbon in a cut portion formed by the cutting step, and applying the heat and pressure in a state where the ribbon is sandwiched by the ribbon sandwiching step; And a thermocompression bonding step of thermocompression bonding the part.

[0006] Thus, after the ribbon is sandwiched between the cuts around the side surface of the plate-shaped member to be the coating section, a cosmetic applicator can be manufactured only by thermocompression bonding of the cut. The thermocompression bonding here can be performed mechanically, so that the manufacturing time can be reduced.

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 to FIG. 5 are explanatory views for explaining the manufacturing process of the cosmetic applicator of the present invention.

In the manufacturing process of the cosmetic applicator according to the present invention, first, as shown in FIG. 1, an application part constituting member used for applying the cosmetic is punched and formed into, for example, a cylindrical plate shape.
Thereby, the cylindrical plate-shaped member 10 is manufactured. Here, what is punched and formed as a coating member is, for example,
NR, NBR foam, polyurethane, etc.

Next, as shown in FIG. 2, an I-shaped cut is made around the side surface of the cylindrical plate member 10 to form a cut portion 11. The notch in this step is not limited to the I-shape as shown in FIG. 2, but may be, for example, a V-shaped or U-shaped notch 1 as shown in the sectional views of FIGS.
It may be 1a, 11b or the like.

After the notch 11 is formed, next, FIG.
As shown in FIG.
Insert When the heat welding material 12 is inserted in this step, it is appropriate to insert the heat welding material 12 so as not to leak outside the cutout portion 11.

After the heat welding material 12 is inserted, the ribbon 20 is sandwiched between the cuts 11 so as to hang on the upper half of the cylindrical plate-like member 10 as shown in FIG.

Finally, heat and pressure are applied to the whole while the ribbon 20 is sandwiched, and the whole is thermocompression-bonded and drawn to manufacture the cosmetic applicator 1 as shown in FIG.
Here, since the notch 11 is provided in the columnar plate-shaped member 10, the resilience of the columnar plate-shaped member 10 at the time of thermocompression bonding can be suppressed, and mechanical processing by a hot press machine or the like can be performed well. I can do it.

As described above, the cut portion 11 is provided, the ribbon 20 is sandwiched between the cut portions, and the mechanical thermocompression treatment can be performed. Therefore, the conventional manual bonding process can be omitted. Manufacturing time can be greatly reduced.

(Other Embodiments) The present invention is not limited to the above embodiment, and various modifications can be made.

For example, the liquid heat-sealing material 12 in the heat-sealing material insertion step described with reference to FIG. 3 may be in a tape shape.

FIG. 8 is a view showing an example of a double-sided adhesive tape used as a substitute for the liquid heat welding material 12. As shown in FIG.

As shown in FIG. 8, in the step of inserting the heat-sealing material described with reference to FIG.
A ring-shaped double-sided adhesive tape 12a having 0 can be used. Here, the reason why the double-sided adhesive tape 12a is formed in a ring shape is that it is adapted to the shape of the cut portion 11 of the cylindrical plate-shaped member 10. Further, the notch 120 is provided in a part to facilitate insertion into the notch 11.

FIG. 9 is an explanatory diagram of a manufacturing process when the above-mentioned double-sided adhesive tape 12a is used.

When the double-sided adhesive tape 12a is used, two double-sided adhesive tapes 12a are sandwiched between the cuts 11, and a ribbon 20 is inserted between the tapes.
In between. After sandwiching the ribbon 20, the heat-sealing material 1
As in the case of using No. 2, the upper and lower sides are thermocompression-bonded from the outside in a state where the double-sided adhesive tape 12a is sandwiched, and the whole is adhesively fixed.

When the two double-sided adhesive tapes 12a are inserted into the cut portions 11, a double-sided adhesive tape 12a having release paper on both sides is prepared. After the release paper is removed and inserted into contact with the upper and lower surfaces of the cutout portion 11, the remaining release paper of each adhesive tape is removed. This step may be a manual operation or a mechanical operation by a machine robot.

As described above, it is possible to manufacture the cosmetic applicator 1 which can be mechanically processed at the time of thermocompression bonding even if a tape-shaped material is used.

As still another embodiment, FIG.
As shown in FIG. 0, after forming a coating member such as an NR foam into a cylindrical shape by punching and forming the same, the outer periphery of the member is partly shaved.
The cutting may be performed at 0.

The shaving process performed here is performed, for example, by rounding to stabilize the cosmetic applicator 1 as a finished product to a predetermined shape. The cosmetic applicator 1 is manufactured according to the above-described process using the cylindrical plate-shaped member 10 having a rounded peripheral surface. According to this embodiment, a cosmetic applicator with a higher degree of perfection can be manufactured.

As described above, according to the method for manufacturing a cosmetic applicator according to the present embodiment, it is not necessary to perform a bonding operation around the side surface of the cylindrical plate-shaped member 10 by a manual operation related to a conventional ribbon mounting operation. Further, since no skill of the operator is required in each manufacturing process, the manufacturing time can be shortened, and a large amount can be manufactured inexpensively by a machine.

[0026]

As described above in detail, according to the present invention, after the ribbon is sandwiched in the cut portion around the side portion of the plate-like member serving as the coating portion, the cosmetic coating can be performed only by thermocompression bonding of the cut portion. Tools can be manufactured. The thermocompression bonding here is
Since mechanical processing is possible, manufacturing time can be significantly reduced.
