又，將筆記用具本體2讓筆尖32插入蓋子4的開口部，而使筆記用具本體2與蓋子4嵌合。為此，在蓋子4的內部，於開口部附近形成有嵌合用的突起，並在與筆記用具本體2嵌合時在能夠被覆筆尖端前端的位置，以藉複數個安裝凸條54支持的狀態配設有杯狀的橡膠密封件8(橡膠製的筆尖端被覆構件)。此外，形成有複數個空氣通路，以由開口部側的空間貫通蓋子本體5的上端(安裝凸部51與環狀筒部52之間)。 Further, the writing instrument body 2 is inserted into the opening of the cover 4 by the pen tip 32, and the writing instrument body 2 is fitted to the cover 4. For this reason, in the inside of the cover 4, a fitting protrusion is formed in the vicinity of the opening, and when it is fitted to the writing instrument body 2, the position at which the tip end of the pen tip can be covered is supported by a plurality of mounting ridges 54. A cup-shaped rubber seal 8 (a rubber pen tip covering member) is provided. Further, a plurality of air passages are formed to penetrate the upper end of the cover body 5 (between the attachment convex portion 51 and the annular tubular portion 52) from the space on the opening side.
前述修飾層6，為施加了文字、圖案花樣、著色、光致發光材料(表現金屬光澤或稜鏡效果的材料)等裝飾的部分，利用印刷、轉印、蒸鍍等方法形成。又，在形成修飾層時，由於安裝凸部51的頂部(設置修飾層6的面)較外周的環狀筒部52的上端面突出，所以不會附著環狀筒部52的端面等能夠容易且確實地橫跨頂部全面形成。在本實施形態中，形成有金屬光澤層作為前述修飾層6。具體來說，藉熱壓金屬蒸鍍薄膜在頂部端面轉印有金屬光澤層，構造成 能將來自外部的入射光以高反射率反射。在利用轉印形成修飾層6時，由於頂部端面較環狀筒部52的上端面突出，金屬光澤層不會附著至環狀筒部52或蓋子本體5，而能夠橫跨安裝凸部51的頂部全面，形成均等的金屬光澤層。又，作為金屬光澤層以外的光澤層，也可以使用如全像片或干涉膜等稜鏡層。在此情況，由於視覺感知到的輝度會成虹色，可得另一種高貴裝飾效果，而特別有用。 The modified layer 6 is a portion to which a decoration such as a character, a pattern, a coloring, or a photoluminescence material (a material exhibiting a metallic luster or a enamel effect) is applied, and is formed by a method such as printing, transfer, or vapor deposition. Further, when the decorative layer is formed, the top portion of the mounting convex portion 51 (the surface on which the modified layer 6 is provided) protrudes from the upper end surface of the outer circumferential annular cylindrical portion 52, so that the end surface of the annular tubular portion 52 does not adhere easily. And indeed formed across the top. In the present embodiment, a metallic luster layer is formed as the above-mentioned modified layer 6. Specifically, the hot-pressed metal evaporated film is transferred with a metallic luster layer on the top end surface, and is configured The incident light from the outside can be reflected at a high reflectance. When the decorative layer 6 is formed by transfer, since the top end surface protrudes from the upper end surface of the annular cylindrical portion 52, the metallic luster layer does not adhere to the annular cylindrical portion 52 or the cover body 5, and can straddle the mounting convex portion 51. The top is comprehensive and forms an equal metallic luster layer. Further, as the gloss layer other than the metallic luster layer, a tantalum layer such as a full image sheet or an interference film may be used. In this case, it is particularly useful because the visually perceived luminance is an iridescent color, and another noble decorative effect can be obtained.
前述修飾層6被成為裝飾構件的頭冠7被覆，而該頭冠7是外嵌於前述安裝凸部51之具透明性的樹脂成形物。為此，修飾層6成為能夠避免因與外部接觸而剝落的構造。又，因前述裝飾構件7是以透明樹脂材料(即、具有無色透明、著色透明、乳白色透明等光透過性的材料)成形，由於能透過裝飾構件7由外側目視內部的修飾層6，藉修飾層6與裝飾構件(頭冠7)的加乘效果，能夠得到高設計性。特別是，在頭冠7的內側或外側施加切割面的情況，會成為由於漫射而造成明亮的裝飾物，在將頭冠7的頂部作成半球形的情況，則由於可得到透鏡效果，能夠授與修飾層6放大或彎曲等視覺效果。 The modified layer 6 is covered with a crown 7 which is a decorative member, and the crown 7 is a resin molded article which is externally fitted to the mounting convex portion 51 and has transparency. For this reason, the finishing layer 6 has a structure capable of avoiding peeling due to contact with the outside. Moreover, since the decorative member 7 is formed of a transparent resin material (that is, a material having light transmissivity such as colorless transparency, coloring transparency, and milky white transparency), the decorative layer 6 can be visually modified from the outside through the decorative member 7 The addition effect of the layer 6 and the decorative member (head crown 7) can achieve high design. In particular, when the cut surface is applied to the inner side or the outer side of the crown 7, the bright decoration is caused by the diffusion, and when the top of the crown 7 is made hemispherical, the lens effect can be obtained. A visual effect such as enlargement or bending of the finishing layer 6 is imparted.
在本實施形態中，其為裝飾構件的頭冠7是由透明的聚碳酸酯樹脂所構成的略圓蓋狀成形物，在其外面施加有複數個切割面71造成的多面切割(即，由形成複數個略三角形或略四角形等略多邊形面而成的所謂晶體切割)。更具體來說，裝飾構件7具有由側方環狀地包圍安裝凸部51的筒部73，以及連接筒部73並由上方覆蓋安裝凸部51頂部的 頭部74。而，頭部74形成為半球狀。 In the present embodiment, the crown 7 of the decorative member is a substantially dome-shaped molded product composed of a transparent polycarbonate resin, and a multi-faceted cut by a plurality of cutting faces 71 is applied to the outside thereof (i.e., A so-called crystal cut is formed by forming a plurality of slightly polygonal faces such as slightly triangular or slightly square. More specifically, the decorative member 7 has a cylindrical portion 73 that surrounds the mounting convex portion 51 by a side annular shape, and a connecting cylindrical portion 73 and covers the top of the mounting convex portion 51 from above. Head 74. However, the head portion 74 is formed in a hemispherical shape.
又，在其為裝飾構件之頭冠7的內面，形成有用以與安裝凸部51外面之環狀凸條53嵌合的嵌合部72。前述嵌合部72位置成使安裝凸部51與裝飾構件(頭冠7)的嵌合位置不會從環狀筒部的上端面突出。即，蓋子4的環狀筒部52的上端面，較安裝凸部51與裝飾構件(頭冠7)的嵌合位置或是嵌合部72，在軸方向上位置於上方。換句話說，蓋子4的環狀筒部52的上端面，位置成較安裝凸部51與裝飾構件(頭冠7)的嵌合位置或嵌合部72，朝軸方向更離開本體部50的上端。依據這樣的配置，由於使安裝凸部51與裝飾構件(頭冠7)的嵌合處變得不會被目視，從而提高設計性，且頭冠7成為不會從上方被拔出的構造。由外側目視頭冠7時，由於從外側透過頭冠7到達金屬光澤層6的光線會以高反射率反射，並在頭冠7的切割面71上漫射，而會視覺感知到更高輝度的光澤。因此，能形成具優異設計性的筆記用具。 Further, on the inner surface of the crown 7 which is a decorative member, a fitting portion 72 for fitting with the annular ridge 53 on the outer surface of the attachment convex portion 51 is formed. The fitting portion 72 is positioned such that the fitting position of the attachment convex portion 51 and the decorative member (head crown 7) does not protrude from the upper end surface of the annular tubular portion. That is, the upper end surface of the annular cylindrical portion 52 of the cover 4 is positioned above the axial direction in the fitting position of the attachment convex portion 51 and the decorative member (head crown 7) or the fitting portion 72. In other words, the upper end surface of the annular cylindrical portion 52 of the cover 4 is positioned closer to the fitting position of the mounting convex portion 51 and the decorative member (head crown 7) or the fitting portion 72, and is further away from the main body portion 50 in the axial direction. Upper end. According to such an arrangement, the fitting portion of the attachment convex portion 51 and the decorative member (head crown 7) is prevented from being visually observed, thereby improving the design, and the crown 7 is not pulled out from above. When the head crown 7 is visually viewed from the outside, since the light reaching the metallic luster layer 6 from the outside through the crown 7 is reflected at a high reflectance and diffused on the cut surface 71 of the crown 7, a higher luminance is visually perceived. Gloss. Therefore, it is possible to form a writing instrument with excellent design.
除此之外，對前述構成的蓋子，在使用全像片形成除金屬光澤層外用以呈現光澤的稜鏡層作為修飾層6的情況下，從外側目視頭冠7之際，由於從外側透過頭冠7到達稜鏡層的光線以高反射率反射時會放出虹色輝度，並在頭冠7的切割面71上漫射，而會視覺感知到具複雜色相的光澤。因此，能形成放出另一種輝度之具優異設計性的筆記用具。 In addition, in the case of the cover having the above-described configuration, when the enamel layer for forming a gloss other than the metallic luster layer is used as the decorative layer 6 using the hologram, when the crown 7 is visually viewed from the outside, it is transmitted from the outside. When the light of the crown 7 reaches the enamel layer is reflected by the high reflectivity, the rainbow color is emitted, and the light is diffused on the cut surface 71 of the crown 7, and the gloss of the complex hue is visually perceived. Therefore, it is possible to form a writing instrument with excellent design that emits another kind of brightness.
