DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pencil type cosmetic having a wooden shaft and a cosmetic core contained in the axial direction thereof, and more particularly to a UV-curable resin (hereinafter abbreviated as "UV resin film") film. The present invention relates to a pencil-shaped cosmetic product formed between a cosmetic core and a wooden shaft, and a method for producing the same.

[0002]

2. Description of the Related Art The main steps of manufacturing a conventional pencil type cosmetic are listed as follows.

[0003] 1. Shaft plate process (1) Lumber (large split, small split, wood cutting), (2) Planer,
(3) cutting, (4) steaming, degreasing, (5) degassing, (6) dye +
Injection of paraffin emulsion under pressure, (7) drying 2. Woodworking process
(4) Drying, (5) Shafts, (6) Trimming 3. Painting process

[0004] In the pencil-shaped cosmetics manufactured according to such a process, the components contained in the cosmetic core, for example, oils, fats, fragrances, and ether-like oils diffuse and penetrate into the wooden shaft. It had the following disadvantages.

[0005] That is, the cosmetic core itself becomes thin because oil is released from the cosmetic core, and as a result, the cosmetic core is detached from the wooden shaft, and the cosmetic core is hardened or fragile due to a decrease in oil content in the cosmetic core. It became difficult to use.

Further, substances contained in the wood shaft (resin,
Lignin and the like) are decomposed by the ether penetrating into the wooden shaft, and as a result, the odor peculiar to the cosmetic is changed, and as a result, the odor is caused.

Heretofore, the following processing has been attempted on the surface of the cosmetic core in order to eliminate such a defect.
(1) Curable resin coating, (2) Metallic powder coating, (3) Immersion coating in thin liquid of chemical glue or synthetic resin, (4) Coated metal coating, (5) Metal foil Adhered or coated

[0008]

However, the cosmetic core is
Soft, susceptible to damage and vulnerable to heat. Therefore, when the above-mentioned processing is performed on such a cosmetic core, the cosmetic core is deteriorated and its outer dimensions are not uniform, and it has been difficult to manufacture a pencil-type cosmetic product having a constant quality.

In order to solve such a problem, a synthetic resin having impregnating property is applied to the wooden shaft during the pressure injection of the emulsion liquid of the dye and paraffin in the shaft plate process. An impregnation layer is formed on the core to prevent the composition of the cosmetic core from penetrating into the wood shaft (Japanese Patent Publication No. 61-18444).

However, the impregnation of the synthetic resin must be performed by mixing the synthetic resin with a dye and paraffin emulsion. For this reason, a step of adjusting the mixed solution is added, which causes an increase in manufacturing cost.

Further, in recent years, since a shaft plate which has already been subjected to the shaft plate process has been imported, it has become virtually impossible to newly form a synthetic resin-impregnated layer.

The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide a pencil-type cosmetic product in which a component contained in a cosmetic core does not diffuse to a wooden shaft, and a method for producing the same. It is to be.

Another object of the present invention is to provide a pencil type cosmetic product in which the cosmetic core and the wooden shaft are not separated, and a method for producing the same.

It is a further object of the present invention to provide a pencil-type cosmetic product which does not deteriorate the cutting ability of a wooden shaft during use, and a method for producing the same.

Still another object of the present invention is to provide a pencil-type cosmetic product in which the quality of the cosmetic core hardly changes, and a method for producing the same.

Still another object of the present invention is to provide a pencil-type cosmetic product in which a cosmetic core is not damaged by the transfer and imprinting of characters and symbols on the painted surface of the pencil-type cosmetic product, and a method of manufacturing the same. It is to provide.

[0017]

A pencil-shaped cosmetic product of the present invention which achieves the above object has a wooden shaft and a cosmetic core contained along the axis, and the cosmetic core, the wooden shaft and UV between
A resin film is formed.

The method for producing a pencil-shaped cosmetic product of the present invention comprises:
(1) a step of forming a groove for inserting a cosmetic core into the shaft plate; (2) a step of applying a UV resin paint to the groove; (3)
Irradiating the applied coating film with ultraviolet rays to form a UV resin film; and (4) applying an adhesive to a portion of the shaft plate where the shaft plates are in contact with each other, and cosmetics in the grooves. The method includes a step of inserting a core and bonding the shaft plates together, and (5) a step of cutting the bonded shaft plate into a pencil shape.

Another method for producing a pencil type cosmetic according to the present invention comprises the steps of (1) forming a groove for centering a cosmetic core on a shaft plate, and (2) forming a shaft plate between the shaft plates. A step of applying an adhesive to a contacting part, inserting a cosmetic core having a UV resin film formed on the surface thereof into a groove, and bonding the shaft plates together, and (3) a bonded shaft plate. A UV resin film is formed by applying a UV resin paint to a cosmetic core and irradiating the applied film with ultraviolet rays.

The cosmetic core used herein may contain a volatile component, and the cosmetic core may have not only a circular cross section but also a polygonal cross section.

[0021]

[Function] Since UV resin cures and becomes a dense layer when irradiated with UV light, apply UV resin paint to the groove of the shaft plate or the surface of the cosmetic core, and irradiate the applied film with UV light. Thus, a pencil type cosmetic having a dense and strong external resin UV resin film between the cosmetic core and the wooden shaft is formed.

Even if this UV resin film is formed on the surface of the cosmetic core, there is no need to apply heat during the formation, so that the cosmetic core does not deteriorate.

From the cosmetic core in which the UV resin film is formed between the cosmetic core and the wooden shaft, the constituent components do not substantially diffuse and penetrate into the wooden shaft, and the pencil-type cosmetics maintain stable quality. I do. In addition, by having a UV resin film, rigidity is given to pencil-type cosmetics.

[0024]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, a preferred embodiment of the production of a pencil type cosmetic according to the present invention will be described. Subsequent to (or instead of) the step (7) in the above-mentioned ordinary shaft plate processing, as shown in FIG. 1, a UV resin paint is spray-coated on the shaft plate 1 by the nozzle 3 as shown in FIG. .

In the embodiment of FIG. 1, the UV resin paint is applied to the entire shaft plate 1. However, since the composition of the cosmetic core diffuses into the shaft from the groove 2 formed on the shaft, the groove 2 is mainly used. (Or groove
2 only) is desirable. In particular, when the adhesive between the shaft plates to be described below and the UV resin paint are poorly compatible (that is, when the UV resin inhibits the adhesion), the UV resin paint is applied to the grooves. .

Here, the main component of the UV resin used is an ultraviolet curable paint (preferably an allyl-based paint).
Although it is commercially available under the name of resin coating, there is no particular limitation as long as it is cured by irradiation with ultraviolet rays to form a dense film.

The application is preferably performed by a spray method as shown in FIG. 1, and a uniform coating film can be formed. However, the coating method is not limited as long as a desired film can be formed. For example, a coating film may be formed by dip coating.

After application of the UV resin coating, ultraviolet rays are irradiated for 20 to 30 seconds. UV resin is cured by irradiation of ultraviolet light,
A resin film A (see FIGS. 2 and 3) is formed. The thickness of the formed UV resin film is appropriately determined.

After the UV resin film A is thus formed, the cosmetic core 4 is inserted into the groove 2, and the other shaft plate on which the UV resin film is similarly formed is coated with an adhesive. The adhesive is applied through the intermediary (FIG. 2). The adhesive may be applied to portions where the shaft plates are in contact with each other.

In the above description, the UV resin film A is
The UV resin coating is applied to the surface of the cosmetic core to be inserted as described above, and the applied film is irradiated with ultraviolet rays to form a UV resin film. The shaft plates may be centered in the groove 2 and bonded to each other.

In FIG. 3, the laminated shaft plates are individually cut, cut into a pencil-shaped wooden shaft 5, and processed. As shown in FIG. 3, a UV resin film is wrapped around the cosmetic core (in the figure, the UV resin layer is exaggerated for clarity).

Although the cosmetic core 4 used here is circular, a UV resin film may be formed between the cosmetic core 4 and the wooden shaft 5. An oval shape may be used. In addition, the material that can be used as the shaft plate is generally wood, but may be a material whose composition can diffuse from the cosmetic core, a porous synthetic resin, processed paper, or the like.

The UV resin film thus formed is dense and strong despite being a thin film, so that the components of the cosmetic core do not diffuse to the wood shaft, Quality is maintained and the feeling of use is less likely to change.

The pencil type cosmetic of the present invention is used in the same manner as ordinary pencil type cosmetics by shaving the wooden shaft and the cosmetic core at the tip and exposing the cosmetic core. When the UV resin film is formed in the groove of the wooden shaft, there is no UV resin film on the cosmetic core, and even if the UV resin film is formed on the surface of the cosmetic core, From being shaved,
The UV resin film is not substantially exposed to the outside and does not come into contact with the skin during makeup.

[0035]

According to the present invention, the UV resin film formed around the cosmetic core of the pencil type cosmetic according to the present invention is dense and strong. Eliminating the ingredients on the shaft and thinning the cosmetic core are eliminated.

Further, since the UV resin film has good cutting properties,
Sharpness of the wooden shaft when shaving the wooden shaft to cut out the cosmetic core,
It is the same as when there is no UV resin film.

Further, usually, characters, symbols, etc. are transcribed and stamped on the painted surface of the pencil type cosmetic product by stamping.
Since the resin film becomes a protective film that is strong against external force, it does not damage the cosmetic core at the time of engraving. Similarly, when dropped, it becomes a strong protective film, and the cosmetic core is less likely to break.
