【発明の詳細な説明】
本発明は、:r5強度を大幅に向上させた鉛筆型コンテ
、すなわち、2分割された軸とそれに収納すべき石とを
接着剤を用いて一体化したもの。DETAILED DESCRIPTION OF THE INVENTION The present invention is: A pencil-shaped conte with greatly improved strength, that is, a two-piece shaft and a stone to be stored in it are integrated using an adhesive.
に関するものである。It is related to.
従来より、鉛線型コンテの石は、製造方法より「焼成し
た石」と「焼成しない芯」とがあった。Traditionally, there have been two types of stone for lead wire conte, depending on the manufacturing method: ``fired stone'' and ``unfired core.''
前者は、高温で熱処理する為、:r5強度は高いが描き
味が悪く、また、顔料の熱変色の為、有彩色のコンテ芯
は作れなかったなどの欠点があつた0
後者は、描き味は良く、また、有彩色の石を作ることも
可能だが芯強度が低く、描画時はもちろんのこと芯を削
る際にも、芯が折れやすいという欠点があった。その為
描画時にも、芯を削り出す際にも1石を折らないよう十
分注意が必要であり、削り器等による簡便な芯の削り出
し方法は採れなかったものである。この、芯強度が低い
ということは、芯を鉛筆型の軸に収納する際、:r5の
成分が接着剤の溶剤により、膨潤する為に芯本来の強度
が大幅に低化することによるものである。Since the former is heat treated at high temperatures, it has disadvantages such as :r5 high strength but poor drawing quality, and it was not possible to make colored conte cores due to thermal discoloration of the pigment0. Although it was possible to make colored stones, the core strength was low and the core was prone to breakage not only when drawing but also when cutting the core. For this reason, great care must be taken not to break a single stone when drawing or carving out the core, and it was not possible to use a simple method of carving out the core using a sharpener or the like. This low core strength is due to the fact that when the lead is stored in a pencil-shaped shaft, the :r5 component swells with the solvent in the adhesive, which significantly reduces the core's original strength. be.
そこで1本発明者らは鋭意研究の結果、焼成しないコン
テ芯の細孔を利用して、コンテ芯の表面及び表面近傍に
、ワックスを層状に含有させることKより、芯に撥水性
をもたせ、接着剤の溶剤による芯強度低化を防止し、高
温で熱処理しなくても1石強度が十分保てる方法を考え
ついたものである。Therefore, as a result of intensive research, the inventors of the present invention have found that by utilizing the pores of the unfired container wick to contain wax in a layer on the surface and near the surface of the container wick, the wick can be made water repellent. We have come up with a method that prevents the core strength from decreasing due to adhesive solvents and maintains sufficient single-stone strength without heat treatment at high temperatures.
コンテ芯に撥水性を持たせる方法の一つとして+15を
撥水性物質により、コーチ°イングする方法がある。し
かし、この方法は、コーティング層の剥離による芯強度
低化を生じやすく、また、コーティング層の厚みによる
芯径のバラツキにより軸収納時1石折れや接着不良が起
こる。One method of imparting water repellency to the conte core is to coach +15 with a water repellent substance. However, with this method, the strength of the core tends to decrease due to peeling of the coating layer, and variations in the core diameter due to the thickness of the coating layer cause the shaft to break during storage or cause poor adhesion.
又、他の方法として9芯金体にワックス等の油分を含有
させる方法がある。しかし、この方法では、軸収納後の
芯強度低化は防げる代わりに、芯が硬くなりすぎ描き味
が悪くなる。更にはコンテ特有のボカシができ々く々す
1発色も悪くなるという欠点がある。Another method is to add oil such as wax to the nine-core metal body. However, this method does not prevent the lead strength from decreasing after the shaft is stored, but the lead becomes too hard and the drawing quality becomes poor. Furthermore, it has the disadvantage that it produces blur, which is characteristic of Conte, and the color development is also poor.

形状に削られる。これにエリ、本発明の鉛筆型コンテに
おいて描画Vこ用いられる部分は、描画に適した芯内部
の「焼成しない」[ワックスを含まない」部分である。On the other hand, the present invention's container core utilizes the pores of the container core that is not fired to contain wax in a layer on and near the surface of the container core, which prevents peeling of the water-repellent portion and decreases the core diameter. There is no variation, and the majority of :r5 is "unfired" (which is dangerous because it contains wax), so the drawability as a conte is not impaired. This is because when a pencil-shaped storyboard is used for drawing, it is generally used with a knife, sharpener, etc., exposing the shaft from the core. At that time, :r5 is cut into a conical shape or a shape close to it. In addition, in the pencil-shaped conte of the present invention, the part used for drawing is the "unfired" [wax-free] part of the core suitable for drawing.
又、描画に適さないワックスを含んだ部分は制器及びナ
イフ等にて削り落されることになる。Also, the portions containing wax that are not suitable for drawing are scraped off with a tool, knife, or the like.
よって1本発明の鉛筆型コンテは、何ら、コンテとして
の特徴を損わないものである。Therefore, the pencil-shaped storyboard of the present invention does not impair its characteristics as a storyboard in any way.
以上の点から、:r5を高温で熱処理することなく、黒
を始め多くの有彩色の鉛筆型コンテについても十分芯強
度を保った。変色のない鮮やかな発色のものが得られる
ことを見い出し9本発明を完成したものである。From the above points, without heat-treating :r5 at high temperatures, sufficient core strength was maintained for pencil-shaped containers in many chromatic colors including black. The present invention was completed after discovering that it was possible to obtain a product with bright coloration without discoloration.

出来なくなり好ましくない。Also, modified products, mixtures of three or more, machine oil?
It is also possible to use a mixture with a liquid wax such as halaffin oil. Using only liquid wax such as machine oil or rough-in oil is not preferable because the internal Kt of the core will not cause the popping characteristic of conte containing oil force I.

Thereafter, in order to create pores in :r5, the dried product is immersed in wax heated and melted at 90 to 200°C for 1 to 5 minutes. Next, the above-mentioned container core was housed in a key shaft using an adhesive to obtain nine pencil-shaped containers of the present invention.
