Description

  The present invention relates to a writing instrument member and a writing instrument using the same. Specifically, the present invention relates to a writing instrument member used as a writing instrument exterior having an image formed on the outer surface, and a writing instrument using the same.

Conventionally, as a means for forming an exterior decoration on the outer surface of a writing instrument, an image of a product name, a company name, etc., an uneven formation by engraving into a molding die, direct printing by screen printing, pad printing, etc. have been widely used. (For example, see Patent Documents 1 to 3).
The image formed by forming the unevenness can be formed without the need for post-processing such as printing because the image can be integrally formed at the time of molding the member by engraving into the mold. However, it was inconspicuous to apply as a decorative part. In addition, it was difficult to obtain sufficient visibility even when the textured surface was textured or textured.

The image by direct printing has high visibility and can be decorated in a colorful manner by using a plurality of printing inks. However, since the printed image formed on the outer surface is easily peeled off by rubbing, it may not be visible after long-term use. In order to solve this problem, a technique for printing on the inside of a transparent exterior member has been disclosed (for example, see Patent Document 4).
By applying the technique of Patent Document 4, it is possible to prevent the printed image from being scratched, and thus the visibility is not deteriorated due to peeling, but the place where it can be applied is limited, such as being unable to form a cylindrical member. End up. Furthermore, even when applied to non-cylindrical members such as clips, it is necessary to assemble the clip member formed separately from the shaft cylinder and cap after printing, which increases the number of parts and requires an assembly process. Become.
In addition, the image formation by direct printing described in Patent Documents 2 to 4 requires a post-processing using a special ink for the writing instrument member, resulting in an increase in manufacturing cost.

  The present invention can form an image without limiting the types of members used as a writing instrument exterior and without increasing the number of parts, and the formed image does not cause peeling due to abrasion or the like, and has long-term visibility. A writing instrument member having a high decorative effect and a writing instrument using the same are provided.

The present invention requires a writing instrument member that constitutes a writing instrument exterior and on which an image having a retroreflective surface is formed.
Furthermore, the retroreflective surface is a wide angle prism type retroreflective surface, and the wide angle prism type retroreflective surface is a full cube corner type retroreflective surface.
Furthermore, it is required that the writing instrument member is a resin molded product, the retroreflective surface is integrally formed on the outer surface when the writing instrument member is molded, and the resin molded product is formed of a transparent resin material.
Furthermore, it is a requirement that the writing instrument member is a kind selected from a cap, a clip, a shaft tube, a crown, and a tail plug.
Furthermore, a writing instrument using any one of the writing instrument members is required.

According to the present invention, it is possible to form an image without limiting the types of members used as a writing instrument exterior or increasing the number of parts, and the formed image exhibits good visibility for a long time without causing peeling due to abrasion or the like. A writing instrument member having a high decorative effect and a writing instrument using the same.
Moreover, since the retroreflective surface is formed by direct processing into the cavity of the mold, an integral image can be formed at the time of molding, so that a highly visible image can be formed at a lower cost.

It is a general-view figure which shows an example of the writing instrument using the writing instrument member (cap) of this invention. It is a principal part enlarged view of the image formation part of FIG.

Embodiments of the writing instrument member 1 and the writing instrument 5 using the same according to the present invention will be described with reference to the drawings, but are not limited thereto.
The writing instrument member 1 is a component used as a writing instrument exterior, on which an image 2 having a retroreflective surface 4 (full cube corner type retroreflective surface 3) is formed on the outer surface.

  The retroreflective surface refers to a surface that exhibits a reflection phenomenon (retroreflection) in which incident light returns to the incident direction again regardless of the incident angle, and is a surface that exhibits a special optical reflection mechanism. . In the retroreflection, unlike the reflection of a mirror or the like having an incident angle equal to the reflection angle, the diffusion of light due to irregular reflection is small, and the light received from the outside is reflected back to the light source as it is. It will be clearly visible.

As the retroreflective surface, a capsule lens type retroreflective surface made of high refractive glass beads, an encapsulated lens type retroreflective surface, an exposed lens type retroreflective surface, or a wide angle prism type retroreflective surface made of a prism element (transparent triangular pyramid) is applied. A wide-angle prism type retroreflective surface that can be retroreflected in many ways is particularly suitable.
The wide-angle prism-type retroreflective surface exhibits reflection toward the light source using three surfaces as compared with glass beads that receive light at a part of the sphere, so that it reflects more intense light and expresses clear visibility. Among them, a full cube corner type retroreflective surface is particularly preferably applied.

The full cube corner type retroreflective surface 3 is a kind of reflective surface using a prism element, and is clearly associated with the contrast between the prism element forming surface and the non-formed surface due to the retroreflective relationship between incident light and reflected light. It imparts visibility.
A trihedral prism element (a shape in which the inside of a triangular pyramid is viewed from the bottom surface side) generally applied as the prism element has a retroreflective surface and a non-retroreflective surface near the corner. The contributing area is partially absent (specifically, the area contributing to retroreflection is about 60%). On the other hand, the full cube corner type retroreflective surface 3 is formed by arranging only the retroreflective surfaces 4 formed on the trihedral prism element (see FIG. 2), so that the entire surface contributes to the retroreflection. In addition, a clearer image can be made visible.

Formation of the retroreflective surface 4 (full cube corner type retroreflective surface 3) includes integral formation at the time of forming a transparent writing instrument member, formation by pressing a pattern on a transparent portion of the writing instrument member, transfer or pasting of a retroreflective sheet, etc. It can be formed by means.
In particular, a retroreflective pattern (full cube corner type retroreflective pattern) is engraved (engraved) on the cavity surface of the mold (uneven portion where the image is formed), and transparent resin (including colored and translucent) is used. Thus, the image 2 provided by forming the writing instrument member 1 by injection molding or the like is more useful because the visibility of the image 2 is good and noticeable, and the post-processing to the writing instrument member 1 is unnecessary. It is.

  The writing instrument member 1 is a writing instrument exterior component composed of a material such as resin, metal, wood, ceramic, etc., and constitutes a writing instrument exterior such as a cap, clip, shaft tube, crown, tail plug, etc. In addition to those used as the above, parts that are visible from the outside, such as a type covered with a transparent film, an inner cylinder covered with a resin-made transparent outer cylinder, etc.

The writing instrument member 1 in FIG. 1 is a transparent resin cap body having a head crown and an inner plug, and a concave image 2 of “ABC” is formed on the side surface.
On the cavity surface of the mold for molding the cap main body, a convex portion that becomes an image of “ABC” is formed, and on the top surface of the convex portion (that is, the plane in the concave portion of the image 2 to be formed). A full cube corner type retroreflective pattern is formed. Although the top surface of the convex portion of the cavity is formed in a flat shape, it can be curved according to the curved surface of the cylindrical cap, and the obtained character surface can be curved.
The cap body is molded by performing injection molding using a desired resin material (for example, transparent polycarbonate resin) using the mold. At that time, a concave image 2 of “ABC” having a full cube corner retroreflection surface 3 is integrally formed on the surface of the obtained cap body. Therefore, the concave image 2 can be visually recognized as a clear “ABC” character with high visibility.
In this embodiment, the concave image 2 is formed on the side surface of the cap. However, a convex image may be used as long as the full cube corner type retroreflective surface 3 is provided on the surface (outer surface of the protruding portion).
In addition to the image 2 by the retroreflective surface, it is also possible to provide a conventional print form image.

The cap is provided with a bullet-shaped fiber chip at the tip, and is fitted into a marking pen body in which an ink storage body filled with ink is installed, whereby the writing instrument 5 (cap-type marking pen) is configured. The marking pen body was provided with an exterior (shaft body) that was an opaque colored resin molded product, and the image 2 was clearly visible even in the cap-fitted state.
As the writing instrument 5, a writing pen of a general-purpose form such as a marking pen or a ballpoint pen using an exterior made of a material such as resin, metal, wood, ceramic, etc., and a fountain pen or a mechanical pencil can be applied.

  As the marking pen, for example, a pen tip for a marking pen such as a fiber tip, a felt tip, a plastic tip, or a metal processing tip is attached to a writing tip portion, and an ink is stored in an ink occlusion body made of a fiber bundle accommodated inside the shaft cylinder. A structure that supplies ink to the writing tip, contains the ink directly inside the shaft cylinder, and is placed at the writing tip by interposing an ink flow rate adjusting member made of comb grooves or a fiber bundle. Examples include a structure for supplying a fixed amount of ink, and a marking pen for storing ink directly in the shaft cylinder and supplying a predetermined amount of ink to the writing tip by a valve mechanism.

  Further, as the ballpoint pen, for example, it has an ink containing tube filled with an ink composition in a shaft cylinder, and the ink containing tube communicates with a chip having a ball attached to the tip, and further, on the end surface of the ink A structure in which the ink backflow prevention body is in close contact, a tip is connected to the tip of the shaft cylinder, and the ink composition is directly filled in the shaft cylinder, and a structure in which the ink backflow prevention body is in close contact with the end face of the ink. A structure that supplies ink to the chip by impregnating the ink occlusion body made up of the contained fiber bundles, a comb groove-like ink flow rate adjusting member, and an ink flow rate adjusting member made of the fiber bundle intervenes to give a predetermined amount of ink to the chip. A ballpoint pen or the like having a structure for supplying

The writing instrument 5 has a protruding and retracting mechanism such as a knock type, a rotary type, a slide type, etc., in addition to a cap type provided with a cap for covering the nib (tip) as in the present embodiment, and the nib in the shaft cylinder. It is also possible to use a retractable form that can accommodate. In addition, when it is set as a retractable form, it can also be set as not only the type which accommodates one refill, but the duplex type which can accommodate two or more refills and can selectively appear and disappear.
Alternatively, a double-headed form may be used in which different types of pen nibs are mounted, or pen nibs for deriving inks of different hues are mounted.
