Description

[Detailed Description of the Invention] The present invention relates to an improved camellia-shaped eyebrow material, specifically, "eyebrow applied to a technical salmon mechanical pencil,
The present invention relates to bar-shaped cosmetics such as eye shadows and lipsticks.

Conventionally, in mechanical pencil type twilled IQ ship charges,
Retractable types using cellulose acetate, polyvinyl chloride, etc. are commonly used as covering materials, but since the strength and hardness of these covering materials are greater than the inner core of the rod-shaped cosmetic core, they can be easily used in case of inconvenience. Although it is possible to protect the inner core, it is inconvenient because the container's unwinding mechanism is insufficient, and once it has been unwound, the inner core cannot be returned to its original position unless it is touched directly by hand. The inner core is easy to break from the part where it is fed out, and when the core is shaved with a cutter, the coating material is difficult to scrape, resulting in damage to the inner core or twisting of the salmon material. It is often said that the economy is satisfactory.

In order to solve these problems, we applied the outer coating material (inner core protective material) used in pencil-shaped cosmetic bars, for example, a mixture of polystyrene and polyethylene mixed with wood such as incense fern or glass fiber. Some studies are considering using it as a covering material for mechanical pencil-type twilled salmon materials. However, if wood is mixed in, it is currently technically impossible to mold it into a tube with a thickness of less than 1 inch, and if glass fiber is mixed in, Because of its own high hardness and strength, when the inner core is cut with a core sharpener, the inner core becomes threaded, which not only makes it less pleasant to look at, but also impairs its external shape. Additionally, cut-type mechanical pencil-shaped cosmetic sticks with an inner core coated with a hardening resin have been exceptionally found, but the bending strength is low and the inner core cannot be adequately protected when applied in a normal amount. .

Therefore, in order to increase the bending strength, a method of increasing the thickness of the coating film by, for example, overcoating has been considered, but this method is not only uneconomical but also has the disadvantage that the coating film becomes non-uniform in thickness. The present invention solves the problems of such a conventional structure, and not only does it prevent the inner core from breaking during transportation, use, and replacement, nor does it stain hands when replacing it, but also eliminates the phenomenon of blooming. The object of the present invention is to provide a mechanical pencil-shaped twilled sharpening material that is free from scratches, can be easily sharpened with a lead sharpener, and can be decorated to give a beautiful appearance and increase product value. It is something.

That is, in order to achieve the above-mentioned object, the rod-shaped IQ core of the present invention has the outer periphery of the rod-shaped IQ core mainly composed of one or more of olefinic polymers, wax, and inorganic powder. It is characterized by being covered with a village-like covering material.

Hereinafter, specific examples of the present invention will be explained with reference to the drawings. 1 is about 1 to 4 ribs in diameter, which is applied to a cosmetic mechanical pencil;
A comb-shaped cosmetic core for eyebrows, eyeliners, eye shadows, lipsticks, etc. with a length of about 20 to 40 ribs, the outer periphery of which is coated with olefin polymers, waxes, inorganic powders, and ethylene-vinyl acetate copolymerization if necessary. Thickness of 0.1 to 2.5 mm, the main material is one or more of fatty acids, higher fatty acids or their metal salts, and esters. It is covered with a pipe-shaped covering material 2 about the size of the ship's side.

To explain the coating material 2 constituting the present invention in more detail, olefin polymer 25-70, wax 5-30, inorganic powder 10-50 (wt%), ethylene-pynylacetate copolymer 5-30, It is made by adding 5-2 higher fatty acids, 5-1 higher fatty acid metal salts, 1-15 (wt%) Festers, and further adding appropriate amounts of colorants and fragrances.
Examples of the olefin polymer include high-pressure or low-pressure polyethylene or polypropylene, and waxes include paraffin wax, microcrystalline wax, ceresin wax, ozokerite, beeswax, and wood wax (hydrocarbon wax is preferred). Examples of inorganic powders include talc, kaolin, stepmother, bennite, calcium carbonate, magnesium carbonate, and calcium silicate. In addition, the ethylene-vinyl acetate copolymer preferably contains 14 to 4% by weight of vinyl acetate, and the higher fatty acids include ethylene-vinyl acetate copolymers having 16 or more carbon atoms, branched fatty acids,
Either saturated or unsaturated fatty acids may be used, but straight-chain saturated ones are preferred, and the higher fatty acid metal salts are preferably metal salts of the higher fatty acids, particularly calcium, magnesium, zinc, and aluminum metal salts of palmitic acid and stearate. Examples of the esters include isopropyl myristate, isopropyl/gremitate, dioctyl phthalate, and octyl stearate. Other additives used include epoxy resin, stearamide, silicone, colorants, and fragrances. The coating material components listed here are selected and used as appropriate depending on the properties of the desired comb-like cosmetic, but for the hakama, polyethylene is used as an olefin polymer, ceresin wax, microcrystalline wax, and inorganic powder are used as waxes. Mica, calcium carbonate, a copolymer containing vinyl acetate ig~2% by weight as the ethylene monovinyl acetate copolymer, calcium stearate and magnesium as the higher fatty acid metal salts, and in addition to this, an appropriate coloring agent, When perfumes are combined, an ideal coating material can be obtained which is satisfactory in terms of free machinability, strength, temperature resistance, etc., by adjusting the content thereof.

The rod-shaped salmon material according to the present invention is produced, for example, as follows.

That is, first, an olefin polymer alone or a mixture of this and ethylene monovinyl acetate copolymer is put into a kneader and melted at 120 to 150°C, and then the temperature is lowered to 110 to 115°C and other coating material components are added. In addition, the mixture is thoroughly dispersed by flooding for 30 to 90 minutes, and then formed into a plate shape, cooled, and then pulverized, or formed into pellets using an extruder.
Next, by ordinary molding means such as injection molding or extrusion molding, the wall thickness is preferably 0.1 to 2 mm, preferably 0.1 to 0.5 mm, and the inner wall is 1 mm.
A pipe-shaped covering material 2 of about 4 ribs is formed into an appropriate length,
Inside the tube is heated and molten, and the core material for inspection materials such as blue, eyeliner, lipstick, etc., which is in the heating and softening female machine, is injected into the tube. The fee shall be paid. The core of the above-mentioned IQ-hoko material may be those used in ordinary salmon material, such as waxes, pigments, hydrocarbons, fats and oils, higher fatty acids, etc., which are appropriately selected.

As detailed above, the present invention provides the outer periphery of the rod-like I○ shipboard core using one or more of olefin polymers, waxes, and inorganic powders, optionally ethylene-pynylacetate copolymer,
Since it is coated with a coating material containing higher fatty acids, their metal salts, esters, etc. as the main material, it prevents the core from breaking during transportation, use, and replacement, and also prevents the core from breaking during replacement. Not only does it prevent your hands from getting dirty, it also eliminates the blooming phenomenon, and it can also be decorated with letters, designs, etc. by printing or other means on the outside, giving it a beautiful appearance and significantly improving the product value. It can be easily and comfortably sharpened, especially with a core sharpener.

Furthermore, by forming a thread-like insert at the base of the covering material, it can be attached to a mechanical pencil for eqsa without fear of falling off. Next, examples of the covering material of the twilled straw hat material according to the present invention will be shown.
