Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a make-up applicator, particularly a simple cosmetic applicator for use before an in-store beauty treatment, and a method for manufacturing the same.

There are various types of makeup such as lipstick, blusher, and eye shadow, and the applicators for these cosmetics have traditionally been made of hair such as horse hair or goat hair, or foams such as rubber or polyurethane. A suitable applicator is used. especially,
Foams have the advantages of being relatively cheap in material cost compared to hair, being porous and retaining cosmetics well, and being flexible and soft to the touch. Therefore, it has been used frequently in recent years.

On the other hand, when selling makeup cosmetics, there is a strong tendency to actually try it on, and in this case as well, cosmetic applicators are used. However, it is not sanitary to apply cosmetics to an unspecified number of people using the same applicator during trial application, considering the intended location of the application (i.e., lips, lips, etc.). Therefore, when different people try to apply the cosmetic, it is necessary to wipe the applicator with tissue paper or wash and dry the applicator each time.

Conventional applicators are expensive and it would be uneconomical to throw them away after each use. That is, the applicator for applying hair is quite expensive because hair is a natural product. There are also applicator tools that use foam as applicator pieces. Such an applicator can be used by (1) forming an application part by covering the surface of the M plate-shaped synthetic resin core with a foam, and then connecting the application part to the complement with an adhesive; or (2) The thin part that serves as the core and the thick (thick) part that serves as the handle in the application part are formed by integrally molding a hard synthetic resin complement coated with foam, or (3) ) The narrow part serving as the core and the wide part serving as the handle in the application part are formed by integrally molding a short flat plate (constant thickness) made of hard synthetic resin and covered with a foam.

In this way, complement can be attached separately to the application part, (2),
As shown in (3), in order to use complements of a specific shape, each piece must be molded one by one, making it relatively expensive. In particular,
Applicator tools whose core and handle are made of a short flat plate of uniform J9 size as disclosed in Japanese Patent Publication No. 49368 and Japanese Patent Publication No. 52-19502 have the following problems as an applicator. In terms of size, in order to apply Kashiri, it is better for the core to be moderately flexible and easy to swallow, and on the other hand, it is better for the handle to be moderately rigid.However, In the method disclosed in the above-mentioned publication, the handle and the core are formed of short flat plates of uniform thickness, so even though the width of the flat plates is changed, it is difficult to meet the conflicting requirements mentioned above. Difficult to satisfy.

In addition, in the manufacturing method of the applicator as disclosed in Publication No. 11EI'57-4324, a core body molded into a very special shape is used, and the handle is attached later.
The cost is quite high.

Furthermore, in the manufacturing method disclosed in Japanese Patent Publication No. 52-49368, short flat plates must be arranged on the conveyor belt at predetermined intervals, but since the short plates are short, they cannot be easily transferred from the hopper onto the conveyor belt. It is difficult to arrange.

In the manufacturing method disclosed in Japanese Patent Publication No. 52-19502, the short plates must be arranged neatly one by one in the recesses of the stand that supports them, but since the short plates have a special shape, this process is time-consuming. It takes.

The present invention has been made in view of the above background, and its purpose is to provide an extremely inexpensive and easy-to-use coating tool that can be disposable even during in-store beauty guidance, etc. An object of the present invention is to provide a manufacturing method thereof.

The cosmetic applicator of the present invention for achieving the above object is characterized by comprising a rod-shaped handle portion having a substantially uniform cross section in the longitudinal direction, and a flat plate-like core portion continuous with the handle portion; and a core are integral, and the core is covered with a porous coating piece. Further, the manufacturing method of the present defense includes a first step of heating and compressing the end of a rod with a uniform cross section made of thermoplastic synthetic resin and forming it into a flat plate shape, and a flat plate obtained in the first step. a second step of applying an adhesive to both sides of the flat plate-like part; a third process of covering the flat plate-like part with adhesive obtained in the second step with porous sheets from both sides; The present invention is characterized in that it consists of a fourth step of widening and forming the coated porous sheet 1 to a shape larger than the flat plate-like portion contained therein from the upper surface of the coated porous sheet 1 to 1q in the step of step 1.

The present invention will be explained below based on examples.

FIGS. 1(a) to 1(e) are cross-sectional views for explaining the manufacturing process of the applicator of the present invention. Figure 2 (a) to (e)
) are plan views corresponding to FIGS. 1(a) to (e), respectively.

As shown in FIGS. 1 and 2, a rod 10 having a substantially uniform cross section in the longitudinal direction is provided. The rod 10 is formed by extrusion molding a thermoplastic synthetic resin such as polypropylene, polyethylene, polyvinyl chloride, polyester, polyamide, polystyrene, styrene acrylonitrile, acrylnyl-butadiene, or the like.

Note that this rod 10 may be a solid rod or a hollow rod. Although the cross-sectional shape of the rod 10 is not particularly limited,
A circular or regular polygonal shape is preferred.

Next, the ends (one end or both ends) of the shipping rod 10 are compressed using a heating press 20, and as shown in FIG.
Set to 1. This flat plate-shaped portion 11 becomes the core of the applicator.

The portion of the rod 10 other than the flat plate-shaped portion 11 becomes a handle portion 12 (see FIG. 2(b)). At this time, the thickness of the flat plate-like portion 11 is set to a level that provides appropriate flexibility. □ As shown in FIG. 1(C), the adhesive 13 is coated on one or both sides of the flat plate-shaped portion 11 using an adhesive coating device 30.

As the adhesive 13, an emulsion type adhesive or a solvent type adhesive 13 made of vinyl acetate type, acrylic type, urethane type, rubber type, etc. is suitable. Moreover, hot melt adhesive 13 can also be used. The adhesive may be applied by a spray method, a roll coating method, a dipping method, or the like. In either method, it is desirable to uniformly apply the adhesive 13 to the flat plate-like part 11 to enhance the adhesion effect of the porous sheet for applying cosmetics 15 to the flat root-like part 11 in the next step.

Next, as shown in FIG. 1(d) and FIG. 2(d), a long porous sheet for applying cosmetics is attached to the flat plate-shaped portion 11. -15 is supplied continuously or intermittently to bond the flat plate-shaped portion 11 so as to cover it from both the front and back surfaces. At this time, only the IQ flat plate portion 11 is covered so that the porous sheet 15 does not cover the handle portion 12.

Since the porous sheet 15 for applying cosmetics is used as the application piece 16, it is preferable that the porous sheet 15 contains the cosmetics well and has a good texture. Preferred materials include foams such as foamed polyurethane, foamed rubber, and foamed polyvinyl chloride, as well as nonwoven fabrics, woven fabrics, and knitted fabrics made from various types of 111E. In addition, depending on the application, to improve the usability,
It is possible to use a material in which hairs or grains are planted on the surface of the material.

Next, the porous sheets 1 to 15 for applying cosmetics are adhered to the flat plate portion 11 using an appropriate cutting device, such as a punching machine.
is cut by punching or the like in a size larger than the flat root-like part 11 corresponding to each flat plate-like part 11.
An application piece 16 is formed containing the . When the porous sheet 15 for applying cosmetics has heat-adhesive properties, the cutting blade is j13.
It is preferable to carry out inversion heating at the same temperature so that the peripheral edges of the upper and lower application pieces 16 are connected to each other.

Note that the shape of the punch can be freely changed by changing the shape of the punch die depending on the purpose of use.

An example of an apparatus for continuously carrying out the method of the invention will now be described according to FIG. A long rod having a substantially uniform cross section in the longitudinal direction obtained by extrusion molding is continuously supplied, and cut into a predetermined length by a cutter 21 to obtain a short rod 10. Short rods 10 are stored in a hopper 22 and carried out one by one from the lower end of the hopper 22. As shown in Figure 4, there are conveyor bells 1 and 2 below the hopper.
3 is placed. On the top surface of the conveyor held 23,
A large number of rod housing grooves 24 are formed at equal intervals, and the rods 10 discharged from the hopper 22 are transferred to the conveyor bells 1 to 23.
lli' is accommodated in this groove 24 one by one as it moves. The rod 10 is housed so that one end (FIG. 3) or both ends (not shown) protrude from the conveyor bell 1-23.

When the conveyor heddle 23 moves and the rod 10 comes to a position corresponding to the heating press 20 consisting of a pair of upper and lower heads, the conveyor bell 23 stops and the heating press 20 is activated. That is, the end of the rod 10 protruding from the conhair belt 23 is sandwiched between the upper and lower heads of the heating press 20 and heated and compressed to form the flat plate-shaped portion 11. When the hot pressing is finished, the compressor belt 23 moves in the same direction again. Thus, in this embodiment, the conveyor belt 23 moves intermittently.

When the rod 10 reaches a position corresponding to the neck adhesive application m HIf¥30, the adhesive 13 is applied to the upper and lower surfaces of the flat plate-shaped portion 11.

Further, when the contact 23 moves, the rod 10 reaches a position corresponding to the foot roller 41.

By the foot roller 41, continuous porous sheets 1-
15, the rod 1 is moved in accordance with the movement of the conveyor bell 1~
0 end intermittently. The feed roller 41 presses the porous sheet 15 against the flat plate portion 11 coated with the adhesive 13. Porous sheet 1-15 is adhesive 13
The coating is firmly fixed to the flat plate-shaped portion 11.

The conveyor belt 23 then moves until the bar 10 reaches a suitable cutting device, such as a punching machine 51 consisting of a pair of heated heads. The pair of heads presses the porous sheet 15. Due to the peeling, the porous sheet for applying cosmetics 15 coated and bonded to the flat plate-like parts 11 is punched and cut into a size larger than the flat plate-like parts 11 corresponding to each flat plate-like part 11 to form a flat plate. Application piece 16 containing shaped part 11
form. Treated porous sheet for cosmetic Fl application 1
The upper and lower application pieces 16 consisting of 5 are connected to each other at their peripheral edges.

In the above embodiment, the conveyor belt 23 was moved intermittently, but it is also possible to operate it continuously.

In that case, the upper and lower heads of the heating press 20 and the cutting device 51 are reciprocated in synchronization with the movement of the conveyor belt 23. Further, the porous sheet 15 is continuously supplied.

Furthermore, the method of the present invention can be carried out in the same manner as the method disclosed in Japanese Patent Publication No. 52-19502. That is, several stages of rod bodies may be supported on a support base, and hot pressing, application of adhesive, adhesion of the short porous sheet 1, and punching may be performed in sequence.

Further, in the above-mentioned embodiment, hot pressing was performed after cutting the long rod to form the short rod 10.
As shown in Figures (a), (b), and (c), cutting and hot pressing can be performed simultaneously. Fig. 5(a) shows a rod body 10 with flat plate-like parts 11 formed at both ends. Cut the center. 5th
In Figures (1) and (C), a flat plate-like part 11 is formed at one end of a rod 10, and the flat plate-like part and the handle are cut into a cut rice cake 1 as shown by the two-dot chain line using a cutting press device. .

The present invention is manufactured through the above steps, and unlike conventional applicators, the core and handle are not separated. Therefore, the labor of manually adhering the complement and the core is eliminated, the manufacturing process of the applicator is simple, and the manufacturing cost is low.

Furthermore, in the present invention, a rod manufactured by extrusion molding can be used as a starting member for the complement.

Therefore, it is cheaper than conventional applicators that are manufactured from short flat plates that are manufactured one by one by molding.

Furthermore, since the present invention uses rods, the ease of rolling of the rods and the lack of directionality make it extremely difficult to arrange them on a conveyor belt or on a support base.
1I, it is possible to produce applicators continuously and automatically or semi-automatically, and mass-produce applicators at extremely low cost.

The handle of the applicator of the present invention is a rod and is rigid, while the core is a thin flat plate and is flexible, so when applying cosmetics, the handle is easy to hold and the applicator strip can be easily held. The adhered core bends to the appropriate mark, making it easy to apply cosmetics. Further, as mentioned above, since the applicator of the present invention is extremely inexpensive, it can be disposed of during in-store beauty guidance.
