Description

【０００１】
【発明の属する技術分野】
本発明は、特に、化粧用ペンシルの先端部をその長手方向に沿ってスライドさせることによりペンシルの先端部をスライド方向で刃体の刃先に交差させて削るペンシル削り器に関するものである。
【０００２】
【従来の技術】
この種の化粧用ペンシル削り器としては、下記特許文献１の図５にも示されているように回転式のものが一般的であった。しかし、この回転式ペンシル削り器では、化粧用ペンシルの芯に平坦部を形成することができないので、下記特許文献１で示す化粧芯用削り器が提供されている。
【０００３】
この化粧芯用削り器（特に下記特許文献１の図３，４参照）においては、ホルダ部７に取り付けられた削り部５に刃物部４が設けられている。この化粧芯用削り器では、化粧用ペンシル２の先端部１３にある化粧芯１２を刃物部４側へ接近させる前進向きとこの刃物部４側から離間させる後退向きとへ化粧用ペンシル２の長手方向に沿ってスライドさせることにより、化粧用ペンシル２の先端部１３をスライド方向で刃物部４に交差させて削る。

【０００５】
【発明が解決しようとする課題】
しかし、化粧用ペンシル２を前進向きと後退向きとへ往復動させる際、その往復動作が不安定になって削りにくくなる欠点があった。特に、化粧用ペンシル２を前進向きへ移動させる際、化粧芯１２に対し平坦部を形成し過ぎて化粧芯１２が折れ易くなるおそれがあった。
【０００６】
この発明は、ペンシルの先端部に平坦部を形成し得るペンシル削り器を提供するとともに、その平坦部の形成範囲を制限して平坦部を適切な面積にすることを目的としている。
【０００７】
【課題を解決するための手段及び発明の効果】
後記実施形態の図面（図１〜５に示す第一実施形態、図６に示す第一実施形態の別例）の符号を援用して本発明を説明する。

【００２４】
【発明の実施の形態】
以下、本発明の第一実施形態にかかる化粧用ペンシル削り器について図１〜５を参照して説明する。
【００２５】
図１，２に示す化粧用ペンシル削り器１は、円筒状のホルダ２と、このホルダ２の一端部側に挿着されたスライド式ペンシル削り器３（図３参照）と、このホルダ２の他端部側に挿着された回転式ペンシル削り器４（図４参照）とを備えている。
【００２６】
前記スライド式ペンシル削り器３においては、前記ホルダ２の外周で周方向Ｘへ所定円周角度だけ延びるように形成された切欠部５に沿って案内溝６（案内部）が露出し、この案内溝６及び切欠部５を閉塞する開閉蓋７を有している。案内溝６は、周方向Ｘに直交する面上で互いに直交する左右方向Ｙ（ホルダ２の長手方向）と上下方向Ｚ（ホルダ２の半径方向）とのうち、左右方向Ｙの両側になる左右両内側部８と、左右両内側部８間で上下方向Ｚの下側になる内底部９と、左右両内側部８間で上下方向Ｚの上側になる開放部１０とを有している。この開放部１０の一部は、案内溝６における周方向Ｘの前後両側のうち、案内溝６の後側で挿脱口部１１として開放されている。また、この挿脱口部１１から前方へ離間する案内溝６内の前側では、刃体１２が内底部９及び左右両内側部８に嵌め込まれているとともに、この刃体１２よりも前方で開放部１０の一部が回避部１０ａにより開放されている。この案内溝６内で左右両内側部８間に架設された刃体１２の刃先１２ａは開放部１０側に向けて上向きになっているとともに、この刃先１２ａの延設方向（左右方向Ｙ）は周方向Ｘに対し直角に交差している。
【００２７】
前記案内溝６の開放部１０において前記ホルダ２の切欠部５の左右両側には刃体１２の刃先１２ａに面する移動規制板１３が左右方向Ｙで相対向して突設されている。この左右両移動規制板１３は周方向Ｘに沿って湾曲している。
【００２８】
前記案内溝６おいて挿脱口部１１に面する内底部９には汚れ防止手段を備えた載置部１４が形成されている。この載置部１４においては、左右一対の案内板１５が前記左右両内側部８に沿って延びるように互いに平行に形成されているとともに、この左右両案内板１５間には回避溝１６が形成されている。この左右両案内板１５上の案内面１５ａは前記刃体１２の側面１２ｂに対し鋭角で傾斜するように延び、前記回避溝１６内の汚れ防止空間１７がこの左右両案内面１５ａ間で開放部１０に向けて開放されている。
【００２９】
前記回転式ペンシル削り器４においては、刃体１８に隣接する削り孔１９が前記ホルダ２の端面側に開放され、この削り孔１９の入口１９ａを閉塞する開閉蓋２０を有している。この削り孔１９内においては、前記ホルダ２の長手方向（左右方向Ｙ）に沿った回転中心線Ｃに対し傾斜する内周面２１で囲まれる直円錐状孔部２２を有し、この直円錐状孔部２２の底面２２ａと入口１９ａとの間にはこの回転中心線Ｃを中心とする円形状の内周面２３で囲まれる円柱状孔部２４が形成されている。前記刃体１８の刃先１８ａはこの直円錐状孔部２２の内周面２１を含む面上に配設されている。
【００３０】
前記回転式ペンシル削り器４の削り孔１９に化粧用ペンシル２５の先端部２６を挿入して化粧用ペンシル２５の長手方向を中心に回転させると、化粧用ペンシル２５の先端部２６の外周面２６ａが刃先１８ａに当てがわれてその先端部２６が直円錐状に削られ、この先端部２６で直円錐状に尖った芯２７が露出する。
【００３１】
次に、直円錐状の芯２７が露出した化粧用ペンシル２５をこの回転式ペンシル削り器４から前記スライド式ペンシル削り器３に移し、この化粧用ペンシル２５の先端部２６を挿脱口部１１から案内溝６に挿入して押し込む。その挿入により、直円錐状の先端部２６の外周面２６ａが前記左右両案内板１５の案内面１５ａに載せられるとともに前記左右両移動規制板１３の内側に当てがわれて位置決め状態Ｐとなる。その位置決め状態Ｐで、化粧用ペンシル２５の先端部２６は、左右方向Ｙへの動きが左右両側規制部２８（左右両内側部８の内面）により規制され、下方向への動きが下側規制部２９（案内面１５ａ）により規制され、上方向への動きが上側規制部３０（左右両移動規制板１３の内面）により規制される。しかも、この位置決め状態Ｐで、化粧用ペンシル２５の先端部２６は、前記左右両移動規制板１３の内面であるストッパ部３１に当接するため、化粧用ペンシル２５の長手方向に沿ったスライド方向Ｓのうち刃先１２ａ側に接近する前進向きＳＦへの動きが規制される。このスライド式ペンシル削り器３において左右両側規制部２８と下側規制部２９と上側規制部３０とストッパ部３１とで位置決めされた化粧用ペンシル２５の先端部２６が進入する直円錐状空間３２の形態と、前記回転式ペンシル削り器４における削り孔１９の直円錐状孔部２２の形態とは、ほぼ一致する。すなわち、前記スライド式ペンシル削り器３において左右両案内板１５の案内面１５ａ上に直円錐状空間３２の外周面３２ａが互いに交差する頂点３２ｂでなす角度αと、前記回転式ペンシル削り器４において直円錐状孔部２２の内周面２１が互いに交差する頂点２２ｂでなす角度βとが、互いに一致する。また、前記直円錐状空間３２の頂点３２ｂは、スライド方向Ｓに対し直角で且つ刃先１２ａを通る面Ｑよりもスライド方向Ｓの前進向きＳＦへ離間した位置にある。
【００３２】
その後、化粧用ペンシル２５の先端部２６の芯２７を片側ずつ刃先１２ａに当てがった状態で、その先端部２６を案内溝６の挿脱口部１１側から刃先１２ａ側へ接近させる前進向きＳＦと刃先１２ａ側から挿脱口部１１側へ離間させる後退向きＳＢとへ化粧用ペンシル２５の長手方向に沿ってスライドさせる。そのスライド動作により、化粧用ペンシル２５の先端部２６の芯２７がスライド方向Ｓで刃体１２の刃先１２ａに交差してその芯２７の両側には図５に示す平坦部Ｆが順次形成される。その際、前記ストッパ部３１（左右両移動規制板１３の内面）が化粧用ペンシル２５の先端部２６に当接してスライド方向Ｓの前進向きＳＦへの移動力を受ける。また、そのスライド動作時、化粧用ペンシル２５の先端部２６の芯２７が前記載置部１４で回避溝１６内の汚れ防止空間１７を通る。図６に示す第一実施形態の別例においては、この汚れ防止空間１７に代えて、回避溝１６内には汚れの付き難い材質（例えばガラス）からなる汚れ防止体３３が埋め込まれている。また、前記案内溝６において左右両案内板１５間の回避溝１６を省略して形成された案内面にフッ素樹脂コーティングを施してもよい。

BACKGROUND OF THE INVENTION
In particular, the present invention relates to a pencil sharpener that slides the tip of a cosmetic pencil along its longitudinal direction so that the tip of the pencil intersects the blade edge of the blade body in the sliding direction.
[0002]
[Prior art]
As this type of pencil sharpener for makeup, a rotary type is generally used as shown in FIG. However, in this rotary pencil sharpener, a flat part cannot be formed on the core of the cosmetic pencil, and therefore, a cosmetic core sharpener shown in Patent Document 1 below is provided.
[0003]
In this dresser sharpener (see, in particular, FIGS. 3 and 4 of Patent Document 1 below), the cutting portion 5 attached to the holder portion 7 is provided with a blade portion 4. In this cosmetic core sharpener, the longitudinal direction of the cosmetic pencil 2 is set in a forward direction in which the decorative core 12 at the distal end portion 13 of the cosmetic pencil 2 approaches the blade portion 4 side and in a backward direction in which the cosmetic core 12 moves away from the blade portion 4 side. By sliding along the direction, the tip portion 13 of the cosmetic pencil 2 is cut and crossed with the blade portion 4 in the sliding direction.
[0004]
[Patent Document 1]
Japanese Patent Laid-Open No. 2000-318383
[Problems to be solved by the invention]
However, when the cosmetic pencil 2 is reciprocated in the forward direction and the backward direction, the reciprocal operation becomes unstable and is difficult to cut. In particular, when the makeup pencil 2 is moved in the forward direction, there is a risk that the flat portion is formed too much on the makeup core 12 and the makeup core 12 is easily broken.
