Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a pencil-shaped cosmetic product comprising a wooden core that has been processed to prevent components contained in the core of the pencil-shaped cosmetic core from diffusing into the wooden core, and a method for producing the same. Regarding.

The main steps for producing such conventional lead shades are as follows.

L Shaft plate process (1) Sawmilling (large split, small split, wood removal) (2)
Planar (5) Cutting (4) Board making (5) Steaming, degreasing (6) Degassing (7) Pressure injection of dye + halaffin emulsion (11) Drying 2, woodworking process (1) Grooving (2) Core insertion (5) Adhesion, lamination (11) Drying (5) Shaft manufacturing (6) Cutting into small pieces i Painting process In the lead shade manufactured according to such a process, the components contained in the core, such as oils and fats, fats, The following drawbacks occurred because perfumes and ethereal oils diffused and penetrated into the wood shaft. That is, the wick itself becomes thin due to the loss of oil from the wick, which causes the wick to fall out from the wooden shaft, and the decrease in oil content in the wick causes the wick to harden and become brittle, making it difficult to use. Furthermore, the substances contained within the wood shaft (resin, lignin, etc.) are decomposed by the ether that has penetrated into the wood shaft, resulting in a change in the characteristic slope of the wood core, which in turn causes a bad odor. Ta.

Conventionally, in order to eliminate such defects and maintain the strength of the core, the following processing has been attempted on the surface of the core. (1) Curable resin coating, (2) Painting with metal powder paint, (5) Dipping coating in a thin liquid of chemical glue or synthetic resin, (Ll) Vapor-deposited metal coating, (5) Metal foil coating. Paste or cover.

However, cosmetic leads are soft, easily damaged, and sensitive to heat, so when the above-mentioned processing is performed on such leads, the outer diameter of the leads becomes uneven, making it difficult to produce pencil-shaped cosmetics with consistent quality. was difficult to manufacture.

Therefore, the present invention was made in order to eliminate such drawbacks, and its purpose is to form a cosmetic core made of a wooden shaft that has been processed so that the components contained in the cosmetic core will not diffuse into the wooden shaft. An object of the present invention is to provide a pencil-shaped cosmetic product and a method for producing the same.

Another object of the present invention is to provide a pencil-shaped cosmetic product in which the cosmetic core and the wooden shaft do not separate.

Furthermore, another object of the present invention is that when cutting a wooden shaft during use,
It is an object of the present invention to provide a pencil-shaped cosmetic with good cutting properties for the above purpose.

-Furthermore, another object of the present invention is to form a cosmetic core with a wooden shaft that will not be damaged by imprinting or transfer of characters, symbols, etc. on the coating film on the surface of the pencil-type cosmetic product. The object of the present invention is to provide a pencil-shaped cosmetic product for the above purpose.

In order to prevent the components contained in the lead for pencil-shaped cosmetics from permeating and diffusing into the wood core, the present invention is designed to prevent the components contained in the lead for pencil-shaped cosmetics from permeating and diffusing into the wood core. The emulsion is injected under pressure into at least the part of the shaft plate that has the core groove to form the wooden shaft, and a synthetic resin layer is formed inside the shaft plate. It is a pencil-shaped cosmetic product that is formed around a shaft.

The formation of this synthetic resin layer will be explained in detail with reference to the drawings.In the above-mentioned normal shaft board process, the (7th step, i.e., the dyeing process) involves forming a shaft with grooves by making an emulsion of dye and paraffin. This is a process of pressurized injection into the plate, and at that time, a synthetic resin is further mixed and injected to form a synthetic resin layer.Figure 1 shows that the above mixed material is injected into a grooved shaft plate by a nozzle. 1 is a shaft plate, 2 is a groove, and 5 is a nozzle. The layer indicated by A is a layer impregnated with synthetic resin.

FIG. 2 shows a state in which a core is placed on a shaft plate impregnated with synthetic resin, and a similar shaft plate is bonded thereon.

What is important here is that the synthetic resin must be impregnated into the shaft plate. In other words, when the synthetic resin is formed as a layer on the shaft plate, as shown in FIG.
When the two shaft plates are put together, a synthetic resin layer is formed around the core, and a synthetic resin layer is formed between the shaft plates.

In this way, the layer causes problems in terms of the compatibility of the adhesive with the shaft plate when the shaft plates are bonded together with adhesive, and the layer also comes into direct contact with the skin during the entire use of cosmetics. As a result, that layer must be removed each time.

1. Therefore, the bevel angle synthetic resin material used in the present invention is as follows:
It must not form a layer on the shaft plate, but must be completely impregnated into the shaft plate. Commercially available synthetic resin materials that achieve the object of the present invention, such as Cypinol, φ220 Clear Lacquer, Polysol L-100, and Sanding Sealer, are most suitable. FIG. 5 shows a cross section of a lead-jar-shaped cosmetic product which is made by cutting the shaft plate shown in FIG. 2 into hexagonal sections, and as can be seen from this figure, A synthetic resin layer completely surrounds the circumference 9 of the core. Table 1 below shows the main components of the above-mentioned materials used in the present invention and their mixing ratios at the time of coating (the actual materials to be coated are an emulsion of materials, dyes, and paraffin in the following proportions). ).

:1 1 Table 1 In order to show whether the above materials are useful for preventing oil penetration,
A penetration test was conducted by dropping liquid paraffin onto the shaft plate impregnated with each material.The results are shown in the table below.

Table 2 No Penetration Flux High Penetration As can be seen from this table, shaft plates treated with the above materials are extremely difficult to penetrate. However, in this test, it was found that the clear treated board and the sanded board had some problems with the compatibility with the adhesive compared to the normal treated board, but this problem was solved because they were formed into a pencil. If there is, it will not cause any problems.

As mentioned above, the processing of the present invention does not require an increase in the number of conventional processing steps, so not only can conventional equipment be utilized, but the manufacturing cost can be almost the same as that of the conventional method.

The synthetic resin that has penetrated and hardened into the wooden shaft has the effect of preventing the oil content of the cosmetic core from penetrating into the wooden shaft, thereby preventing the core from becoming thinner and preventing reactions between the components contained in the wooden core and the oil.

In addition, the wooden shaft impregnated with synthetic resin has improved machinability when used as a product and when cutting the end of the ship, making it suitable for soft cosmetics.

Furthermore, after finishing the pencil shape, metal foil or vapor-deposited foil is heated and stamped or transferred while applying pressure on the coating film on the surface of the anchor chain, but in pencil-shaped cosmetics using a thick lead, However, the thickness of the wooden shaft had to be thinner, and the pressure during stamping and transfer caused the core to break or become deformed. However, according to the present invention, the wooden shaft is reinforced by the impregnated synthetic resin, so it has the effect of sufficiently withstanding the pressure during stamping and transfer.
