　前記筆記具本体２には、ペン先３２を被覆保護するキャップ４が装着されている。前記キャップ４は、透明樹脂製のキャップ本体５と、その頂部に装飾部材として設けられる頭冠７と、ペン先（ボールペンチップ）３２の先端を被覆するゴムシール８により構成される。 The writing instrument body 2 is equipped with a cap 4 that covers and protects the pen tip 32. The cap 4 includes a cap body 5 made of a transparent resin, a crown 7 provided as a decorative member on the top, and a rubber seal 8 that covers the tip of a pen tip (ballpoint pen tip) 32.
　前記キャップ本体５は、下端を開口した本体部５０と、軸方向に延び出すようにして本体部５０の上端に設けられた取付凸部５１及び環状筒部５２と、を有している。キャップ本体５は、透明なポリカーボネート樹脂からなる略筒状成形物であり、本体部５０と取付凸部５１と環状筒部５２とが一体に形成されている。 The cap main body 5 has a main body portion 50 having a lower end opened, and an attachment convex portion 51 and an annular cylindrical portion 52 provided at the upper end of the main body portion 50 so as to extend in the axial direction. The cap main body 5 is a substantially cylindrical molded product made of a transparent polycarbonate resin, and the main body portion 50, the mounting convex portion 51, and the annular cylindrical portion 52 are integrally formed.
　詳細には、キャップ本体５の本体部５０上端の外縁から環状筒部５２が上方に延び出るように設けられるとともに、該環状筒部５２の内部となる位置に、略円錐台形状の取付凸部５１が本体部５０上端から延び出るように設けられている。取付凸部５１の頂部が環状筒部５２の上端面よりも上方に位置するように、言い換えると、取付凸部５１の頂部が環状筒部５２の上端面よりも本体部５０から軸方向に離間するように、取付凸部５１が本体部５０から突出している。また、取付凸部５１の外面の下方に、頭冠７の乗越え嵌合用の環状リブ５３が形成されている。環状リブ５３は、環状筒部５２の上端から軸方向上方側に突出しない位置に設けられている。つまり、環状筒部５２の上端は、環状リブ５３よりも、軸方向における上方に位置し、本体部５０から軸方向に離間している。 Specifically, the annular cylindrical portion 52 is provided so as to extend upward from the outer edge of the upper end of the main body portion 50 of the cap main body 5, and a substantially frustoconical mounting convex portion is provided at a position inside the annular cylindrical portion 52. 51 is provided so as to extend from the upper end of the main body 50. In other words, the top of the mounting convex portion 51 is separated from the main body portion 50 in the axial direction from the upper end surface of the annular cylindrical portion 52 so that the top portion of the mounting convex portion 51 is positioned above the upper end surface of the annular cylindrical portion 52. As shown, the mounting convex portion 51 protrudes from the main body portion 50. An annular rib 53 for fitting over the head crown 7 is formed below the outer surface of the mounting convex portion 51. The annular rib 53 is provided at a position that does not protrude upward in the axial direction from the upper end of the annular cylindrical portion 52. That is, the upper end of the annular cylindrical portion 52 is located above the annular rib 53 in the axial direction and is separated from the main body portion 50 in the axial direction.
　更に、前記取付凸部５１の頂部（即ち、円錐台の上面）は、表面が平滑な平面、とりわけ図示された例では軸方向に対して垂直な面となっている。そして、取付凸部５１の頂部をなす平面には、加飾層６が設けられている。尚、前記頂部は、平面を斜面状に形成することや、凸状、凹状、立体状等の非平滑面とすることもでき、形状に応じた加飾層６を形成することで様々な意匠性を付与できる。 Furthermore, the top portion of the mounting convex portion 51 (that is, the upper surface of the truncated cone) is a flat surface having a smooth surface, in particular, in the illustrated example, a surface perpendicular to the axial direction. And the decoration layer 6 is provided in the plane which makes the top part of the attachment convex part 51. As shown in FIG. In addition, the said top part can also form a non-smooth surface, such as a convex shape, a concave shape, and a solid shape, in the shape of a slope, and various designs by forming the decoration layer 6 according to a shape. Sex can be imparted.
　また、筆記具本体２をペン先３２がキャップ４の開口部に挿入されて、筆記具本体２とキャップ４とが嵌合する。このため、キャップ４の内部には、開口部近傍に嵌合用突起が形成されるとともに、筆記具本体２との嵌合時にチップ先端を被覆することができる位置にカップ状のゴムシール８（ゴム製チップ被覆部材）が複数の取付リブ５４により支持された状態で配設されている。更に、開口部側の空間からキャップ本体５の上端（取付凸部５１と環状筒部５２の間）を貫通するように、複数の空気通路が形成されている。 In addition, the pen tip 32 of the writing instrument body 2 is inserted into the opening of the cap 4 so that the writing instrument body 2 and the cap 4 are fitted. For this reason, the cap 4 has a fitting projection formed in the vicinity of the opening, and a cup-shaped rubber seal 8 (rubber tip) at a position where the tip of the tip can be covered when fitting with the writing instrument body 2. The covering member) is disposed in a state of being supported by the plurality of mounting ribs 54. Furthermore, a plurality of air passages are formed so as to penetrate the upper end of the cap body 5 (between the mounting convex portion 51 and the annular tube portion 52) from the space on the opening side.
　前記加飾層６は、文字や図柄模様、着色、光輝性材料（金属光沢やプリズム効果を発現する材料）等の装飾が施された部分であり、印刷、転写、蒸着等の方法で形成される。尚、加飾層形成時には、取付凸部５１の頂部（加飾層６を設ける面）が、外周の環状筒部５２の上端面よりも突出しているため、環状筒部５２の端面等に付着することなく頂部全面に渡って容易且つ確実に形成することができる。本実施形態では、前記加飾層６として金属光沢層が形成されている。具体的には、金属蒸着フィルムを熱加圧することで頂部端面に金属光沢層が転写されており、外部からの入射光が高反射率にて反射し得るように構成されている。転写によって加飾層６を形成する際、頂部端面が環状筒部５２の上端面よりも突出しているため、環状筒部５２やキャップ本体５に金属光沢層が付着することなく、取付凸部５１の頂部全面に渡って均一な金属光沢層を形成することができる。尚、金属光沢層以外の光沢層としてホログラムや干渉フィルム等のプリズム層を用いることもできる。この場合、視覚される輝きが虹色となるため、別種の高貴な装飾効果が得られ、特に有用なものとなる。 The decorative layer 6 is a portion provided with decoration such as letters, a design pattern, coloring, or a glittering material (a material that exhibits a metallic luster or a prism effect), and is formed by a method such as printing, transfer, or vapor deposition. The At the time of forming the decorative layer, the top of the mounting convex portion 51 (the surface on which the decorative layer 6 is provided) protrudes from the upper end surface of the outer annular tubular portion 52, and therefore adheres to the end surface of the annular tubular portion 52, etc. It can be easily and reliably formed over the entire top surface without the need to do so. In the present embodiment, a metallic luster layer is formed as the decorative layer 6. Specifically, the metallic gloss layer is transferred to the top end face by applying heat and pressure to the metal vapor-deposited film, so that incident light from the outside can be reflected with high reflectivity. When the decorative layer 6 is formed by transfer, the top end face protrudes from the upper end face of the annular cylinder part 52, so that the metallic luster layer does not adhere to the annular cylinder part 52 or the cap body 5, and the mounting convex part 51. A uniform metallic gloss layer can be formed over the entire top surface of the substrate. In addition, prism layers, such as a hologram and an interference film, can also be used as gloss layers other than a metallic gloss layer. In this case, since the brightness that can be seen is rainbow, a different kind of noble decoration effect can be obtained, which is particularly useful.
　前記加飾層６は、装飾部材となる頭冠７によって被覆されており、該頭冠７は、前記取付凸部５１に外嵌される透明性を有する樹脂成形物である。そのため、加飾層６が外部に接触して剥がれることを防止することができる構造になっている。また、前記装飾部材７を透明樹脂材料（即ち、無色透明、着色透明、乳白色透明等の光透過性を有する材料）により成形することで、装飾部材７を介して内部の加飾層６が外側から視認できるため、加飾層６と装飾部材（頭冠７）との相乗効果によって高い意匠性が得られる。特に、頭冠７の内側や外側にカット面を施した場合には、乱反射による明るい装飾物となり、頭冠７の頂部を半球形にした場合には、レンズ効果が得られるため、加飾層６に拡大や湾曲等の視覚的な効果を付与することができる。 The decorative layer 6 is covered with a crown 7 serving as a decorative member, and the crown 7 is a resin molded product having transparency that is fitted around the mounting convex portion 51. Therefore, it has the structure which can prevent that the decoration layer 6 contacts the exterior and peels. Further, the decorative member 7 is formed of a transparent resin material (that is, a material having light transmissivity such as colorless and transparent, colored and transparent, milky white transparent, etc.), so that the internal decoration layer 6 is disposed outside through the decorative member 7. Therefore, high designability is obtained by the synergistic effect of the decorative layer 6 and the decorative member (head crown 7). In particular, when a cut surface is applied to the inner side or the outer side of the crown 7, it becomes a bright ornament due to irregular reflection, and when the top of the crown 7 is hemispherical, a lens effect is obtained, so that the decorative layer 6 can be given visual effects such as enlargement and curvature.
　本実施の形態では、装飾部材である頭冠７は透明なポリカーボネート樹脂からなる略円蓋状成形物であり、外面には複数のカット面７１による多面カット（すなわち、略三角形や略四角形等の略多角形面を複数形成してなる所謂クリスタルカット）が施されている。より具体的には、装飾部材７は、取付凸部５１を側方から周状に取り囲む筒部７３と、筒部７３に接続し且つ取付凸部５１の頂部を上方から覆う頭部７４と、を有している。そして、頭部７４は、半球状に形成されている。 In the present embodiment, the crown 7 that is a decorative member is a substantially cap-shaped molded product made of a transparent polycarbonate resin, and a multi-faced cut by a plurality of cut surfaces 71 (that is, a substantially triangular shape, a substantially rectangular shape, or the like) on the outer surface. A so-called crystal cut formed by forming a plurality of substantially polygonal surfaces is applied. More specifically, the decorative member 7 includes a cylindrical portion 73 that surrounds the mounting convex portion 51 from the side, a head portion 74 that is connected to the cylindrical portion 73 and covers the top of the mounting convex portion 51 from above. have. The head 74 is formed in a hemispherical shape.
　また、装飾部材である頭冠７の内面には、取付凸部５１外面の環状リブ５３と嵌合するための嵌合部７２が形成されている。前記嵌合部７２は、取付凸部５１と装飾部材（頭冠７）との嵌合位置が環状筒部上端面から突出しないように位置している。すなわち、キャップ４の環状筒部５２の上端面が、取付凸部５１と装飾部材（頭冠７）との嵌合位置あるいは嵌合部７２よりも軸方向における上方に位置している。言い換えると、キャップ４の環状筒部５２の上端面が、取付凸部５１と装飾部材（頭冠７）との嵌合位置あるいは嵌合部７２よりも、本体部５０の上端から軸方向に離間して位置している。このような配置によれば、取付凸部５１と装飾部材（頭冠７）との嵌合箇所が視認されないようになっているため、意匠性が向上するとともに、頭冠７が上方に引き抜かれることがない構造となっている。頭冠７を外側から視認した際、外側から頭冠７を介して金属光沢層６に到達した光が高反射率で反射し、頭冠７のカット面７１で乱反射するため、より輝度の高い光沢が視覚される。よって、意匠性に優れた筆記具を形成できる。 Also, a fitting portion 72 for fitting with the annular rib 53 on the outer surface of the mounting convex portion 51 is formed on the inner surface of the crown 7 that is a decorative member. The fitting portion 72 is positioned so that the fitting position between the mounting convex portion 51 and the decorative member (head crown 7) does not protrude from the upper end surface of the annular tube portion. In other words, the upper end surface of the annular cylindrical portion 52 of the cap 4 is positioned above the fitting position of the mounting convex portion 51 and the decorative member (head crown 7) or the fitting portion 72 in the axial direction. In other words, the upper end surface of the annular cylindrical portion 52 of the cap 4 is axially separated from the upper end of the main body portion 50 rather than the fitting position of the mounting convex portion 51 and the decorative member (head crown 7) or the fitting portion 72. Is located. According to such an arrangement, the fitting portion 51 and the decorative member (the crown 7) are prevented from being visually recognized, so that the design is improved and the crown 7 is pulled upward. It has a structure that never happens. When the head crown 7 is viewed from the outside, the light reaching the metallic gloss layer 6 from the outside through the head crown 7 is reflected with high reflectivity, and is irregularly reflected by the cut surface 71 of the head crown 7, so that the brightness is higher. Gloss is visible. Therefore, a writing instrument excellent in design can be formed.
　これとは別に、前記構成のキャップに対して加飾層６として、金属光沢層以外の光沢を呈するプリズム層を、ホログラムを用いることで形成した場合、頭冠７を外側から視認した際には、外側から頭冠７を介してプリズム層に到達した光が高反射率で反射するときに虹色に輝き、頭冠７のカット面７１で乱反射するため、複雑な色相の光沢が視覚される。よって、別種の輝きを放つ意匠性に優れた筆記具を形成できる。 Apart from this, when a prism layer exhibiting gloss other than the metallic luster layer is formed by using a hologram as the decorative layer 6 with respect to the cap having the above-described configuration, when the crown 7 is viewed from the outside, When the light reaching the prism layer from the outside through the crown 7 is reflected with high reflectance, it shines in rainbow color and diffusely reflects on the cut surface 71 of the crown 7 so that a gloss of complex hue is visually perceived. . Therefore, it is possible to form a writing instrument excellent in design that emits another kind of brightness.
