Description

  The present invention relates to a writing instrument using a phosphorescent material, and in particular, makes it possible to clearly recognize characters and figures drawn on the surface of a phosphorescent layer coated with the phosphorescent material even in a dark place. It relates to writing instruments that can be demonstrated.

  Writing instruments such as ballpoint pens are highly necessary to be used and can be provided at a low cost, and many of them are distributed free of charge as crude or promotional items for store advertisements. In this case, there is an effect that consumers can widely recognize the existence of the store by printing a company name, a telephone number, a catchphrase, a message, etc. on the side of the writing instrument to be distributed, for example, a ballpoint pen.

  However, simply printing characters etc. on the side of the ballpoint pen body is a common practice, so it is difficult to distinguish it from other stores (other companies) and the advertising effect is very high. Absent. In view of this, there is one in which a ballpoint pen main body is formed of a synthetic resin mixed with a phosphorescent material, and characters or the like are printed on the surface of the main body so that it can be recognized even in a dark place. Here, for example, Patent Document 1 discloses that a ballpoint pen is formed using a synthetic resin material mixed with a phosphorescent material. According to this, in a dark place, the phosphorescent material shines to function as a backlight for characters and the like, and it is expected that the characters and the like will be raised to further enhance the advertising effect.

  However, a material in which a phosphorescent material is kneaded into a synthetic resin is not so high in brightness that characters are unclear and impact is weak. Therefore, it is conceivable to apply a phosphorescent material directly to the outer surface of the ballpoint pen body. However, the characters and the phosphorescent material are gradually worn out over a long period of use, so that the outline of the characters etc. is deformed and it is difficult to recognize the characters etc. In addition, there is a problem that the luminance is lowered. In this regard, as a solution to the problem of luminance reduction, for example, Patent Document 2 proposes that the casing has a double structure and is filled with a phosphorescent material.

Japanese Patent Laid-Open No. 9-148202 JP 2001-63269 A

However, according to the method of Patent Document 2, although the luminance can be improved, the use of phosphorescent material increases the cost, and it is applied to a writing instrument that is distributed free of charge as a promotional product. There is a problem that it is difficult to do.
Further, when the phosphorescent material is directly applied to the main body of the ballpoint pen, there is a problem that the phosphorescent layer and the characters printed on the surface thereof are rubbed and the recognizability is lowered.
Furthermore, the synthetic resin material mixed with the phosphorescent material has a problem that the brightness cannot be clearly recognized because the luminance is not so high.

  Therefore, the present invention has been made in view of such problems, and while reducing the amount of phosphorescent material used, it is possible to maintain phosphorescent performance and advertising effects even when the number of days of use increases, and to increase costs. An object is to provide a writing instrument that can be used as a promotional product without inviting.

  In order to achieve the above object, the present invention according to claim 1 is provided with a first cylindrical body provided with a phosphorescent layer coated with a phosphorescent material on the outer surface, and printed with characters, figures, and the like on the surface of the phosphorescent layer. And a transparent second cylindrical body disposed on the first cylindrical body.

  In order to achieve the above object, according to a second aspect of the present invention, in the writing instrument according to the first aspect, the first cylindrical body is made transparent and a phosphorescent material is formed on a part of the first cylindrical body. Light is stored by providing a portion that does not apply or print characters or figures, and allows light transmitted through the second cylindrical body and the first cylindrical body to reach the inner surface of the first cylindrical body. It is characterized by the fact that the phosphor is also stored from the back side of the layer.

  In order to achieve the above object, the present invention described in claim 3 is the writing instrument according to claim 1 or 2, characterized in that the phosphorescent material is a high-intensity long persistence phosphorescent pigment.

  In order to achieve the above object, the present invention according to claim 4 is the writing instrument according to claim 1 or 2, wherein the phosphorescent layer provided on the outer surface of the second cylindrical body has a particle size with high phosphorescent performance. The coarse phosphorescent material is used as a lower layer, and a phosphorescent material having a finer particle size than that of the lower layer is applied as an upper layer to sequentially form a plurality of layers.

  The writing instrument of the present invention forms a phosphorescent layer in which a phosphorescent material is applied by printing or the like on the surface of the first cylindrical body, and prints characters or figures on the surface of the phosphorescent layer to form the first cylindrical body. Since it is housed in a transparent second cylindrical body, it is possible to maintain the phosphorescence performance and advertising effect for a long time without wearing the surface of the phosphorescent layer and the printing surface of letters etc. even if used for a long time Become. Furthermore, since the phosphorescent material is applied in multiple layers by printing, there is an effect that a writing instrument having a high advertising effect can be provided at low cost.

[Structure of writing instruments]
Hereinafter, a writing instrument according to the present invention will be described in detail based on a preferred embodiment. FIG. 1 is a front view showing an embodiment of a writing instrument according to the present invention, and FIG. 2 is a cross-sectional view taken along line AA of the writing instrument shown in FIG. The illustrated writing instrument 10 is specifically a knock-type oil-based ballpoint pen, but is not limited thereto, and may be, for example, an aqueous ballpoint pen, a gel ink ballpoint pen, an emulsion ballpoint pen, or the like. Further, a structure other than a knock type may be used.

  The writing instrument 10 generally includes a refill (also referred to as “replacement core”) 1 that is replaceable and filled with ink 12 (the black-painted portion shown in FIG. 2), and a portion other than the tip of the refill 1. A resin-made cylindrical barrel shaft (main body) 2 (see FIG. 3 (a)), and a phosphorescent layer 30 that is externally fitted to the barrel shaft 2 and is coated with a phosphorescent material by printing are provided. The surface of the phosphorescent layer 30 is made of a transparent resin having a desired printing 31 such as characters and figures, and a cylindrical phosphorescent axis (first cylindrical body) 3, and further transparently fitted to the phosphorescent axis 3 A cylindrical protective shaft (second cylindrical body) 4 made of resin and a tip (tip) 11 provided at the distal end of the refill 1 are screwed and fixed to the lower portion of the barrel shaft 2 and the protective shaft. 4 is a neck shaft (brush tip holder) 5 that functions as a retainer, and the upper end of the body shaft 2 A clip 6 for being sandwiched between breast pockets and the like, and a top screw ("" attached to the upper portion of the barrel shaft 2 so that the lower surface is in contact with the upper end of the refill 1 and a part is exposed from the upper end of the barrel shaft 2 7), which is also referred to as a “push button”.

  As shown in FIG. 1, the refill 1 has a tip 11 as a writing tip at the tip, and the tip 11 has an ink cartridge (not shown) that has a larger diameter and contains a predetermined amount of ink inside. Are connected. When the refill 1 is housed in the body shaft 2, a spring (not shown) is externally fitted to the chip 11, and is inserted into the body shaft 2 from the upper end in this state, and an opening (not shown) at the front end of the neck shaft 5. By inserting the tip of the tip 11 into the hole and fixing the neck shaft 5 to the trunk shaft 2 in this state, the state shown in FIG. 1 is obtained.

  3 (a), 3 (b), and 3 (c) are front views showing the shapes of the body shaft 2, the phosphorescent shaft 3, and the protection shaft 4 of the writing instrument 10 shown in FIG. 1, respectively. First, as shown in FIG. 3A, the body shaft 2 is provided with a female screw 21 for screwing the neck shaft 5 to the tip (chip 11 side). As shown in FIG. 3 (b), the phosphorescent shaft 3 fitted on the barrel shaft 2 has a cylindrical shape, and a phosphorescent material to be described later is applied to the outer side surface over the entire circumference and almost the entire length by printing. The luminous layer 30 thus formed is formed. The surface 31 of the phosphorescent layer 30 is printed with characters 31 and graphics. As a specific example of characters, etc., FIG. 3B shows a company name, a telephone number, a catchphrase, a message, an illustration, etc. for a part or the whole of the surface of the phosphorescent axis 3 (here, “Iloha Tourism” The print 31 is printed with the letters “hotel”, the telephone figure indicating the telephone number, and the number “0123-45-6000” indicating the telephone number. Note that the color of the characters of the print 31 is not limited to black, and may be any number of colors, or a plurality of colors may be appropriately used.

  Next, as shown in FIG. 3 (c), the protective shaft 4 fitted on the phosphorescent shaft 3 has a cylindrical shape, and one end thereof (on the side where the clip 6 is fixed) is shown in FIG. 3 (a). A concave portion 41 that fits into the convex portion 61 is provided. Thereby, even if the neck 5 is loose, the protective shaft 4 can be prevented from rotating carelessly. In addition, as long as the trunk | drum axis | shaft 2, the light storage axis | shaft 3, and the protection axis | shaft 4 are cylindrical bodies, not only a cylindrical thing but a polygonal thing may be sufficient.

  As the phosphorescent material, a high-luminance long persistence phosphorescent pigment is desirable. For example, “Lumi Nova” (registered trademark) manufactured by “Nemoto Special Chemical Co., Ltd.” can be used. This “luminova” does not contain any radioactive material and has the feature of emitting light overnight. And it corresponds to any of printing (screen, flexo, gravure, offset, etc.), painting (water-based paint, solvent-based paint, etc.), and resin molding (injection, extrusion, casting, etc.).

  On the other hand, the body shaft 2 and the phosphorescent shaft 3 are formed of a transparent resin, and the phosphorescent layer 30 is not formed over the entire circumference and almost the entire length of the phosphorescent shaft 3, but a part where the phosphorescent layer 30 is not provided is formed in part. By not printing characters or the like on the portion, the light that has passed through the protective shaft 4 is further transmitted through the portion of the light storage shaft 3 where the light storage layer 30 is not provided and the body shaft 2 to store the light storage layer. The light can be accumulated so that the light can reach the back side of 30. Thereby, the brightness | luminance of the luminous layer 30 can be ensured, and the light emission time can be further extended.

  Here, it is known that the phosphorescent material generally tends to have higher luminance as the particle size is coarser and lower luminance as the particle size is smaller. The clearer the contrast between the phosphorescent material having high luminance and the characters and graphics that act as the light shielding portion, the higher the recognition of the characters and graphics described on the phosphorescent axis 3. However, if the surface of the phosphorescent layer 30 serving as a base on which characters, figures, and the like are printed is rough, the characters may not be clearly recognized and the characters may not be clearly recognized. Therefore, by arranging a coarse-grained phosphorescent material with high luminous intensity and high luminance in the lower layer, the afterglow luminance is secured, and further, a phosphorescent material with finer particle size is arranged on it, and this is repeated further if necessary. As a result, the phosphorescent layer 30 is formed in a plurality of layers to ensure luminous performance and luminance, and the fineness of the granularity of the phosphorescent layer 30 arranged in the uppermost layer makes the outline of printed characters etc. clear. Recognition can be improved.

  That is, as shown in FIG. 4, the lower phosphorescent layer 30 a in which the phosphorescent layer 30 is applied to the lower layer and the coarser phosphorescent material is applied by printing, and the upper portion in which the finer phosphorescent material is further applied to the lower phosphorescent layer 30 a by printing. It can be formed by the phosphorescent layer 30b. Thus, by forming the luminous layer 30 in a plurality of layers while taking advantage of the properties of the coating film, it is possible to enhance luminous performance and luminance, and to clearly print and recognize the outline of characters and the like.

[Effect of the embodiment]
According to the writing instrument according to the present embodiment, a phosphorescent material is applied to the surface of the trunk shaft 2 by printing, and printing 31 such as letters and illustrations is applied thereon, and the phosphor is stored in the transparent protective shaft 4. There is an effect that it is possible to prevent the layer 30 and the print 31 from being rubbed and characters or the like cannot be recognized or the phosphorescent layer 30 is gradually worn and the phosphorescent performance is deteriorated.

  In addition, since the phosphorescent shaft 3 on which the printing 31 is applied is an independent member, even if the order number of the writing instrument 10 from the ordering party is reduced or canceled, the body shaft 2 and the protective shaft 4 are connected to other parts. Since it can be directed to customers and general customers, there is an effect that the loss can be minimized.

  Further, the phosphorescent material is formed by forming the phosphorescent layer 30 on the lower phosphorescent layer 30a coated with a coarser particle size by printing, such as by forming the upper phosphorescent layer 30b coated with a phosphorescent material finer than that on the phosphorescent material. By forming a plurality of layers, the film thickness of the phosphorescent layer 30 can be increased, and a phosphorescent material with a fine particle size is applied on the phosphorescent material while using a phosphorescent material with a coarse particle size with high afterglow luminance, so that characters, etc. There is an effect that printing is finished clearly. And the luminous layer 30 can maintain the afterglow time and brightness | luminance high by the synergistic effect of the luminous performance by the difference in a particle size being exhibited.

  As described above, the preferred embodiments of the present invention have been described in detail. However, the present invention is not limited to such specific embodiments, and is within the scope of the present invention described in the claims of the utility model registration. Needless to say, various modifications and changes are possible. For example, the most frequently used ballpoint pen is used as the writing instrument 10, but other writing instruments such as a pencil, a marking pen, a brush, a paint brush, a fountain pen, and the like may be used.

  Further, as shown in FIG. 5, the body shaft 2 is integrated with the phosphorescent shaft 3 to form the cylinder / light accumulating shaft 8, and the phosphorescent layer 30 and the printing 31 shown in FIG. In this case, the writing instrument 10 can be reduced in weight and cost can be reduced.

  Furthermore, in the above-described embodiment, the print 31 is applied to the trunk shaft 2, but the print 31 may be provided on the protective shaft 4. In this case, in printing, there is a high possibility that characters will be rubbed with long-term use. Therefore, in the case of printing, a transparent seal is stuck on the print 31 for protection, or engraving (recess processing) may be used instead of printing.
