Description of the invention ([Technical Field] The present invention is related to a coating tool for ball pens. The present invention is suitable for especially high-viscosity water-based inks. The structure of coating tools such as ball pens of ink. Hereinafter, "water-based ink" refers to the general term for "oil-based inks" "inks containing water or water-soluble organic solvents." [Background of the invention] All previous ball pens It contains oil-based ink, but in recent years, it has been developed to install a lower-viscosity water-based ink instead of oil-based ink. However, the use of water-based ink has a large amount of ballpoint pen ink *. Oily ink has a low viscosity and the ink holding force in the ball head storage room is weak. Therefore, when the pen tip is placed upward, the ink flows from the ball head storage room to the ink storage side. As a result, the ink in the ball head storage room is white and the ink is white when writing. In response to the following Japanese Gazette, the ball pen structure of the interior is disclosed.

Description of the Invention (2) Figure 25 is a cross-section view of the original pen containing the valve described in Japanese Real Equity 4-52067. The ballpoint pen 100 described in No. 4-52067 is an ink cartridge 10 inserted into the body shaft 10 丨. The ink cartridge 102 is composed of a pen tip 105, an ink containing portion 1, a connecting member 107, and five members of the valve body 108. Among them, the pen tip 105 is a component in which a writing ball head 109 is incorporated. The ink containing section ιo6 is a cylindrical member and contains water-based ink. The connecting member 107 is a member 'that connects the pen tip 105 and the ink container 106 with a through hole 110 at the center. The through hole u0r is provided with a valve seat 111 and a protrusion 113. The aforementioned nib-105 is inserted into the front end of the connecting member 107, on the one hand, the ink container 106 is externally attached to the connecting member 107. In the prior art ball pen 100, a valve chamber 115 is formed between the valve seat 1 Π and the protrusion 113 in the through hole 110 of the connecting member 107. The spherical valve body 108 is inserted into the valve chamber I15. When the ballpoint pen 100 of the prior art is 1050 upward, the valve body 10 8 contacts the opening of the valve seat 111 and the plug valve seat 11 as shown in FIG. 25a. Therefore, the ink in the pen tip 105 can be prevented from flowing backward. -When the pen tip 105 is lowered as shown in FIG. 25B, the valve body 108 leaves the valve seat 11 1 and the valve body 108 is locked by the protrusion 113. Therefore, the ink in the ink containing portion 106 flows into the pen tip 105 side through the gap between the valve body 108 and the protrusion 113. The ballpoint pen 100 of the prior art changes the orientation of the ballpoint pen 100 in the heavens and the earth, moves the ball valve body 108 in the valve chamber 115, allows the ink to flow out to the pen tip 105 side, and prevents the pen tip 105 from reaching the ink containing portion 10 6 side backflow. Therefore, it can improve the ink whitening when writing. -5- (Please read the precautions on the back before filling this page) This paper size applies to China National Standard (CNS) A4 (210 X 297 Public Love) Stamp printed by Employees' Cooperative of Economic Village Intellectual Property Bureau * 40910G A7 B7 V. Description of the Invention (3) However, because the ball pen 100 of the prior art uses the inner wall of the through-hole 10 connected to the tool 107 to form the outer periphery of the valve chamber 115, it has the disadvantage of low forming accuracy of the valve chamber 115. That is, the connecting member 107 is formed by the injection method, but the valve chamber 115 is dug down due to the protrusion 113 provided on the inner peripheral surface of the hole. As a result, the valve chamber was subjected to excessive force during demolding, and the size could not be stabilized. The dimensional accuracy was limited. Because of the above-mentioned problem, the structure of the ballpoint pen i 00 of the prior art makes it difficult to set the gap between the valve chamber 115 and the valve body 108 as optimal. Therefore, the ballpoint pen 100 of the prior art has a gap that is too small and causes the valve body 10g to get stuck. Otherwise, if the gap is too small, the valve body 108 is loose, and the tightness with the valve seat 111 is incomplete. Also, other prior art ball pens have the same problem. That is, the ballpoint pens of the prior art, which are not disclosed in the aforementioned publications, have a low precision in forming the outer periphery of the valve chamber by the connecting members. Therefore, it is not easy to set the gap between the valve chamber and the valve body to be optimal, and the valve body is lacking in smooth work. The i-th object of the present invention focuses on the above-mentioned problems of the prior art, and provides a ballpoint pen that can greatly improve the size precision of the valve body, make the gap between the valve chamber and the valve body optimal, and make the valve body work smoothly and smoothly. [Summary of the Invention] The present inventors have developed a structure in which a valve body—partially or wholly—installed in a child expansion control unit is provided with a diameter-enlarged portion at the pen tip as a countermeasure to achieve the above object. That is, the ballpoint pen developed by the present inventors includes: a pen tip, a ball end for a note is provided at the front end, and an ink guide hole penetrating in the axial direction is provided; an ink receiving section, which contains ink; and a connecting member, which connects the aforementioned pen tip and ink receiving The connecting member is provided with a penetrating hole penetrating the ink containing portion and the pen tip, and the penetrating hole is provided with a -6-paper standard (CNS) A4 rule ^^ · ^ ^ ---- ^- -^ -------- Order --- f -------- line (please read the notes on the back before filling this page) 40910G a? '—_______ B7 _ 5. Description of the invention (4 ) There is a valve house and a pen tip that accommodates a valve body that can be moved in the axial direction and contacts the valve seat. It is characterized in that the ink guide hole of the pen tip is provided with an enlarged 'intermediate body' near the opening on the side of the pen. In the guide hole, the ink guide hole is provided with a locking valve body and the body is locked between the interspace body &lt; the space where the ink passes through. When the pen tip is upward, the valve body contacts the valve seat to prevent the ink from flowing backward. In addition, one part or all of the time body is moved in the ink guide hole and locked at the valve body locking portion, and the ink Void portion flows to the write head side ball. The above-mentioned ballpoint pen system forms a part of the valve chamber with a pen tip rear end portion. That is, the atomic pen is provided with an enlarged diameter portion near the opening of the connecting member side of the ink guide hole of the pen tip, and a part or all of the valve body can be moved in the ink guide hole. The ink guide hole of the pen tip is provided with a valve body locking portion for locking the valve body. Therefore, the valve body moves between the valve seat provided in the through hole of the connecting member and the valve body provided in the ink guide hole, and the ink guide hole of the pen tip has the function of a valve chamber. More specifically: the ink guide hole enlarged diameter portion and the valve body locking portion of the present invention have the function of a valve chamber. Since the nib is generally formed by cutting or the like, the forming accuracy limit is extremely higher than that of the connecting member. Therefore, the enlarged diameter part of the pen tip can be processed with high dimensional precision, which can make the valve body have proper clearance. Furthermore, when the valve body is locked at the valve body locking portion, a gap portion is formed between the valve body locking portion and the valve body. Therefore, when the pen tip is in the downward position, the valve body is locked at the valve body locking portion, and the ink flows through the gap portion to the writing ball head and falls down. As mentioned above, water-based inks have lower viscosity than oil-based inks, but the viscosity is quite different depending on the water-based ink additives.

Description of the invention (5) Ball pen 'Although the ink flow is smooth and the writing is good, when using permanent ink with higher viscosity, sometimes the ink will Fly white. For example, when metallic inks (containing metallic powder inks), dual-color inks, titanium oxide inks, and pearlescent pigment inks are used, the ink is likely to blush, and the book cannot be quickly opened. It is thought that the reason is that due to the high viscosity of the ink, it is difficult for the ink to pass through the gap between the valve body and the trench. It is conceivable that if the area of the groove (gap portion) of the ink passage is enlarged, the ink can flow easily and the whitening can be reduced. However, coating tools such as ball pens, in fact, the whip ease of ink flow is also related to the size of the valve body, and it is not yet known how much the area of the void portion is to ensure a sufficient ink flow. In addition, it is difficult to increase the area of the trench (gap) because of the difficulty in processing. That is, the nib manufacturing system clamps the outer periphery of the wire material of the nib material with a jig, opens the center hole of the ink guide hole, and then cuts the trench which becomes a gap portion by broaching. That is, the broaching tool is pressed into the center hole and the broaching tool is advanced in the axial direction to form a trench. Therefore, during the broaching process, the pushing force of the broaching tool is directly applied to the fixture, but because the fixture clamps the outer periphery of the wire as described above, the gripping force in the axial direction is limited. And because the wire of the pen tip uses relatively soft material, increasing the clamping force of the cooler will hurt the wire. Therefore, when the trench is designed to be enlarged, the centerpiece slides during the broaching process, which significantly reduces the processing precision of the trench. Therefore, the enlargement of the ditch (gap portion) is restricted. The coating tool of the present invention, which was developed to solve the above problems, includes: an ink containing portion, which contains ink; a front end portion, which applies ink; and a coating mechanism of a valve mechanism, wherein the valve mechanism includes: a valve body, which is movable in the direction of ink flow; -8-This paper size is in accordance with China National Standard (CNS) A4 (210 X 297 publicly loved tf. ^ 1 tn mu. ^ 1 I 4 · n 1 ^ 1 --- ^ 1- 1-I ._1 * .1 nn 1 (Please read the notes on the back before filling this page) 409 too A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (6) The valve seat is located on the side of the valve body to the ink containing part ; And the valve seat, which is located from the valve body to the front end side position, and the valve seat is locked to the valve body and there is a gap between the ink body and the valve body. When the front end of the coating tool is upward, the valve body contacts the valve seat to prevent ink. It flows backward from the front end to the ink receiving part, and the valve body contacts the valve seat when the front end of the coating tool is down, and the ink flows to the front end side coating tool through the gap portion. The shape of the valve body contacting the valve seat is Spherical, the valve body and the gap The projected area of the void portion that is not covered by the valve body is projected on a plane orthogonal to the direction of ink flow. The so-called "· projects the valve body and the void portion on a plane orthogonal to the direction of ink flow. The projected area of the gap portion that is not covered by the valve body "refers to the outline of the gap portion from the valve body 8 when the valve body 8 is in contact with the valve seat (valve body locking portion) as shown in Fig. 2b. The area of the protruding portion is specifically equivalent to the oblique line in Figure 2b. When the projected area is 0.035 mm2 or more, the ink sufficiently flows to the front end through the gap, so whitening is unlikely to occur. On the one hand, if the projected area is not full When the ink is 0.035mm2, it is easy to pinch the gap, and it is easy to fly white when writing. Through investigation, it is found that the theoretical artifacts due to the critical effect of the projected area are not well understood, but it can be speculated that even if the gap is large, it will be in the projected image. When the upper body is covered with ink, the ink moves along the surface of the valve body, and it is difficult to move to the front end through the gap. Another coating tool for achieving the same purpose includes a pen tip, and a ball end for a note is incorporated in the front end. An ink guide hole penetrating in the axial direction is provided; an ink containing portion is provided with ink; and a connecting member is connected between the aforementioned pen tip and the ink ------ * III I — II-IIII ί II order--1- I i- --(Please read the precautions on the back before filling this page) This paper size applies the Chinese National Standard (CNS) A4 specification (21 × X 297 mm) 40910c A7 B7 V.

Figures 1 to 8 1 indicates the ballpoint pen of the embodiment of the present invention. In this embodiment, the structure of the ballpoint pen 1 of the same structure as the previous technology is composed of a cylindrical body shaft 2 and an ink core 3. The ink core 3 is formed by a pen tip $, Connecting member, ink same (ink collection Component) 7 and spherical valve body §. I will explain in order-Ming 'pen tip 5 is a member with a writing ball head at the front end, which is made by cutting and machining metal materials such as free-cutting steel. Specifically, the metal used The material is Free Cutting Stainless SteeI DSR6F (manufactured by Datong Special Steel Co., Ltd.), with 20% and Mo, S, Pb, Te added to the base of SUS43 °. The shape of the nib 5 is not as big as known. The difference is that the front end part 17 is conical, and the rear side 18 is cylindrical. The rear end part is provided with a step difference 19, and the step difference 19 is made a slightly smaller diameter on the rear end side. The front end part is set on the rear end side. It has a taper for easy insertion of the connecting member 6. Also, the step difference 19 can be arbitrarily set. The internal shape of the pen tip is as shown in Fig. 1. The front end part has a ball head storage chamber 10 for holding a ball head 10 for writing and a ball head storage The ink guide hole 12 on the rear side of the chamber communicates. In particular, the pen tip 5 used in the present invention is provided with an enlarged diameter portion 13 near the rear end opening of the ink guide hole 12 and an ink guide hole 1 2 Internally formed stepped valve seat (valve body locking part) 1 5.

The description of the invention (11) is as in section 3 In the figure and figure 4, the inner diameter is larger than the other positions of the ink guide hole 12 (the pen tip insertion side). The inner diameter D of the enlarged diameter portion 13 is set to the valve body 8 straight (about 70% to about 150%). A preferred range of the inner diameter D of the enlarged diameter portion 13 is about 110% to about 150% of the diameter of the interbody 8. The reason why the lower limit of the preferred range of the inner diameter D is 110% is that more than one and a half of the valve body 8 can enter the enlarged diameter portion 13. The reason for the upper limit of 150% is that the inner diameter D is expanded when the inner diameter D is larger. The clearance between the part 13 and the valve body 8 will be too large. The axial length h of the enlarged diameter portion 13, that is, the depth of the enlarged diameter portion 13 is preferably in the range of 30% to 90% of the diameter of the valve body 8. In addition, the inner diameter d of the other parts of the ink guide and hole 12, that is, the inner diameter of the central opening when the pen tip 5 is viewed from the rear end side, is preferably in a range of 70% to 90% of the diameter of the carcass 8. The stepped valve seat 15 may be vertically straightened to the inner wall of the enlarged diameter portion 13; conversely, it may also be formed in a bowl-shaped shape when viewed from the rear end at an angle. The valve seat 15 of the ballpoint pen 1 in the embodiment shown in the figure is approximately 120 to the inner wall of the enlarged diameter portion 13. In terms of a specific range, that is, an inclination of about 110 ° to 130 °. The relationship between the shape and size of the main and enlarged diameter portions I 3 is as shown in FIG. 2. It is important that a part of the valve body 8 can enter the enlarged diameter portion 13. The amount of the valve body 8 entering the enlarged diameter portion 13 is preferably the valve body 8 above the equator of the earth. That is, the inlet amount H of the valve body 8 (refer to FIG. 4) is preferably 50% or more of the diameter of the p body 8. The maximum amount of the valve body 8 entering H is recommended to be about 60% to 100% of the diameter of the valve body 8. The recommended range of the above-mentioned entry amount 不受 is not limited by it, but about 40% of the diameter of the valve body 8 may be used, and conversely, such as 120%, the entire body of the valve body 8% ^ ⑯ There is more than enough status.

When the valve body 8 enters the inside of the enlarged diameter portion 13, the valve body 8 contacts a part of the valve seat 5 to prevent it from moving to the front side. At this time, it is ensured that the ink passes through the intermediate body 8 and the enlarged diameter portion 13 and the inner periphery. The gap between them is extremely important. Another feature of the structure is that a groove (gap portion) 6 is provided in the valve seat 5. In this embodiment, the trenches 16 are triangular as shown in Figs. 3, 4, and 5, and eight are arranged at equal intervals. The length of the groove 16 in the axial direction is about 1/3 of the diameter of the valve body 8 as shown in Figure 4 and the seventh circle. ^ The depth of the groove 6 is from the enlarged diameter portion i 3 to the side for writing, the ball head. The 10 side gradually decreases. The connecting member 6 is formed by injection molding of a thermoplastic resin such as a polypropylene resin, and the shape is not significantly different from that of a known one. That is, the front end portion 20 side of the connecting member 6 is conical. The rear end side has a two-stage cylindrical shape, and a large-diameter portion 21 and a small-diameter portion 22 are sequentially provided. A through hole 23 is formed in the center of the connecting member 6 to penetrate in the axial direction. A valve seat 2 5 is provided in the middle of the through hole 23. The shape and size of the valve seat 25 are the same as those known. A positioning step is provided at the front end side of the through hole 23. A characteristic part of the structure of the connecting member 6 is the inner peripheral surface of the through hole 23, and the inner diameter of the position on the front end side of the valve is made small. The inner diameter of the small-diameter portion 28 is equal to the inner diameter 0 of the enlarged handle Shao 13 of the nib 5 as described above. The position of the small-diameter portion 28 corresponds to the position between the small-diameter portion 28 and the valve seat 25 when the pen tip 5 is inserted. The valve body 8 is a ball made of stainless steel, cemented carbide or rhenium, which is difficult to record and has a certain weight. 15 • 15- The paper size is 阙 7cNS) A4 ^ (210 x 297 mm) i — — --- II ^ --- ill--order, —-r—! — —, (Please first Read the back; I will fill in this page again.

409i〇c V. Description of the invention (18) Structure. The water-based inks of the Viscosity Carrier 咼 include metal powder and metallic inks), dual-color inks, and oxidized inks Ά pearl gloss pigment inks. ^ ^ The so-called metallic powder pigment ink (so-called metallic ink) is an ink containing metallic powder pigment such as aluminum powder or brass powder. This ink has a large difference between the specific gravity of the metal material and the liquid component (Vehiele). To prevent the precipitation of metal powder pigments, a thickener is usually added to the liquid component. The double-color-developing ink refers to an ink containing both a dye that easily penetrates the surface to be coated and a dye that does not penetrate easily, for example, a metal powder pigment, a water-soluble dye, water, and a permeable organic solvent. When this ink is coated on a solvent-permeable surface such as paper or cloth to write characters, signs, graphics, etc., the metal powder pigment will display the graphics that maintain the writing, etc., and the water-soluble dye will diffuse to the outside of the graphics, etc. , Showing the appearance of borders just like graphics, with unique visual effects. To prevent metal powders, Shen Dian usually adds thickeners to liquid ingredients. White ink usually contains a titanium oxide (TiO2) pigment. Titanium oxide pigments also have a large specific gravity. To prevent their precipitation, titanium oxide inks are often added with a thickener. Also, Japanese Patent Publication No. 5-46389 describes that in addition to a thickener, high-molecular particles are added to a titanium oxide-containing ink. Bead-containing gloss pigment inks refer to bead-containing gloss pigment inks made of fine powder made of mica and stabilized by covering the surface with high refractive index metal oxides such as titanium oxide and iron oxide. This ink is reflected by the high-refractive-index metal oxide layer, the low-refractive-index mica, and the surrounding media.-21 This paper size is applicable to China Solid Standard (CNS) A4 (210 X 297 mm) ---- -----; -----_ I, Λ .------ II .J --- I-- (Jing first read the phonetic on the back?

Description of the invention (19) Light-like beads or metallic luster is cultivated. This ink Because the specific gravity of the pearl luster pigment i is also large, so a thickener is usually added to prevent the precipitation of the pearl luster pigment. Even if the water-based ink has a higher viscosity than the oil-based ink, the tip of the pen tip is placed upward. Ink drops back to the ink containing part. As a result, the ink at the tip of the pen tip is lost, and the problem of ink blushing occurs when writing. However, when these inks are used on 10,000 sides, the problem of ink blushing and the problem of rapid writing cannot be achieved. The basic structure of Yuanyu Pen 5 0 and the aforementioned ball pen 1 芫All the same 'Only the shape of the nib diameter expanding part and the valve body locking part are different. Therefore, the description of the embodiment focuses on the nib diameter expanding part and the valve body locking part of the important part of the invention', and the other parts are limited to simple explanation. The ballpoint pen 50 in this embodiment is composed of a cylindrical body shaft 2 and a water core 3 as shown in the figure i. The ink core 3 is similar to the prior art by a pen tip 5, a connecting member 6, and an ink cartridge (ink The storage member) 7 and the spherical valve body 8.

Description of the invention (20) The material of the valve body 8 printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is made of stainless steel 'superhard alloy' ceramics and other materials which are not easy to rust and have a considerable density. In particular, non-magnetic materials are preferred for the same reasons as for the aforementioned ball pen 1, and among them, Vostian iron-based stainless steel is particularly preferred. For example, a range of SUS20I to SUS385 is preferable, and more specifically, SUS304 or SUS3I6 is suitable. The valve body 8 is not necessarily spherical, but when the valve body 8 is spherical, its diameter is preferably 1.0 to 2.011111, and 14 to 16111111 is particularly preferred. The nib 5 is a member in which a writing ball head is mounted on the front end and is cut and processed by a metal material. The material of the pen tip 5 is selected in consideration of the degree of difficulty in cutting and the difficulty of recording. For example, it is preferable to use a free-cutting stainless steel. 3 The appearance of the pen tip 5 is the same as that of the aforementioned ball pen 1. In addition, in the internal shape of the pen tip 5 of the ballpoint pen 50 of this embodiment, the front end portion is the same as the ballpoint pen previously described. As shown in the figure, a ball head storage chamber having a ball head 10 for writing is provided with a slave ball. The head accommodation chamber passes through the ink guide holes 12 at the rear end. An enlarged diameter portion 13 is provided near the rear end of the pen tip 5 and a stepped valve seat (valve body locking portion) 15 is formed in the ink guide hole I 2. The shape of the valve seat (valve body locking portion) 5 of the ball pen 50 of this embodiment is different from the ball pen 1 disclosed previously. This is explained in detail below. Fig. 15 (a) is an enlarged cross-sectional view of a joint portion between a ballpoint pen tip and a connecting member according to an embodiment of the present invention. That is, Fig. 15 (a) is a view corresponding to the part of Fig. 4 described above. Fig. 15 (b) is a C-C sectional view of Fig. 15 (a). As shown in FIG. 15 (b), the ballpoint pen I of this embodiment is provided with six light-emitting cross-section rectangular trenches (voids) $ 1. -23-This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) (Please read the notes on the back before filling this page) A .: Order · Line. 4091Q9 at B7 Member of Intellectual Property Bureau, Ministry of Economic Affairs印 Printed by a consumer cooperative V. Description of the invention (21) And the structure of the ball pen 50 of this embodiment is special-mentioning that the ball pen 1 of this embodiment is designed to project the valve body S and the gap portion 5 1 orthogonally to the pump. The projection area of the gap formed by the plane not covered by the valve body 8 is more than 0.035 mm2. In addition, the cutting area of the trench (void portion) 5: 1 of the ballpoint pen 50 of this embodiment is 0.40 mm2 or less. More specifically, the shape of the trench 51 of the ballpoint pen 50 in this embodiment is rectangular from the tip 5 of the pen, and the bee is rectangular when viewed from the side. Let the width of the trench 51 be the factory GW ", the depth be" GH ", and the length be" When GLj, the diameter of the entire body of each ditch (gap portion) 51 is "0D", the diameter of the valve body is "bd", and the number of ditches is η, the following formula (1) holds.

The average particle size of these metal powder pigments is insufficient because the metallic luster of the handwriting is too small, and the pen tip is liable to be jammed when the size is too large, and the ink outflow is poor. Therefore, the average particle size is 5 ~ 30ym, especially when the range is 5 ~ 15p m good. Dual-color inks usually contain: a coloring agent that does not easily penetrate the coated surface, and a coloring agent that easily penetrates the coated surface, and water, and water-soluble organic -25- This paper applies the Chinese National Standard (CNS) A4 regulations ( 210 X 297 mm) ---_------ Ί Ji '------- I ^ —41 — 11!

The ink containing such a coloring agent is also an ink containing a metal powder pigment. Since the specific examples of the metal powder pigment contained in the ink are completely the same as those described above, the enumeration is omitted. The average particle diameter of these metal powder pigments is poor due to the excessively small metallic luster of the handwriting. If the nib is too easy to drain, the ink will not flow out. Therefore, when the average particle diameter is in the range of 1 to 20 m, the writing and printing properties are better. In addition, conventional pigments previously used in permanent inks other than metallic powder pigments can be used as colorants that are difficult to penetrate and penetrate the coated surface. Examples of such pigments include inorganic pigments such as carbon black and titanium oxide, or inorganic pigments such as cyanocridone (quanacridone 4々copper-based or insoluble azo-based pigments such as Hanxihuang 10G).

Titanium oxide is particularly heavy (the specific gravity of aluminum is about 2.7, the specific gravity of mica is 2 · 7 ~ 3.1, and the specific gravity of titanium oxide is about 4). Adding a thickener sometimes results in insufficient precipitation and soil-proofing effect. Therefore, titanium oxide-containing ink is used to prevent titanium oxide. For precipitation, it is better to add polymer particles. In particular, when a flat polymer particle is added, it is more effective than a spherical fluorene molecule particle to prevent oxidative stress. Examples of the flat polymer particles include ethylene glycols such as polyethylene and polypropylene, glycol ether malonate propionate acetate, and condensation--1 ------ ^ ----- --- ^ ---- r -------- ^ (Please read the notes on the back before filling out this page) 27- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) (B) A7 B7 409200 V.

The thickener for the ink used in the ball-point pen 50 of this embodiment can be a thixotropic polysaccharide or its sensor. When a thixotropic polysaccharide or its sensor is used as a thickener, it is easy to prepare so-called "gel-type" ink with thixotropy. That is, the viscosity of the ink is reduced due to the ball head rotation when it is used in a ball pen, which is a characteristic useful for water-based ball pen inks. In particular, it is preferable to use a natural polysaccharide or its susceptor, that is, a microorganism-producing polysaccharide or its susceptor, a water-soluble plant-based polysaccharide or its susceptor, or a water-soluble animal-based polysaccharide or its susceptor. Examples of the microorganism-producing polysaccharides or their susceptors include, for example, Mycorrhizal Polysaccharides, Gut Gum, Gongjin Gum, Lamb Gum, Succinate Dextran, Dextran, and the like. Examples of water-soluble botanical polysaccharides or their sensor bodies include: tragacanth gum, sore gum, tartar gum, low-cast Bingham gum, Guadian gum, arabinogalactan gum, 'arabin gum, and Xi 4 Only cotton Xuanjiao, pectin 'dian powder, sweet 4y di-A cottonseed gum, red bean gum, acetylene carboxylic acid, agar, etc. Water-soluble animal polysaccharides or -29- This paper size applies to Chinese National Standard (CNS) A4 (210 X 297 mm) ~ II 4— nnn an-n tL τκ.

Description of the invention (33) Even if the shape of the gap portion is the same size, if the valve body is large and the gap portion is covered by the valve body on the projection, it is estimated The ink moving on the surface of the valve body tends to deflect from the gap portion and is not easy to move toward the front end portion. Furthermore, it is inferred from the comparison between Comparative Example 1 and Examples 1 to 3 that even though the gap portion is not completely covered by the valve body on the projection view, When the area of the gap portion not covered by the valve body is small, the ink is still difficult to move to the front end side. From Comparative Example 1 (the area of the gap not covered by the valve body 0_ 02 8 mm2), the text is whitish and the writing is difficult during fast writing. Whereas in Example 2 (the above-mentioned projection area is 0.04 mm2) during fast writing Can write smoothly 'Can I tolerate the area of the gap portion that is not covered by the valve body. 〇3 There are several areas near the 5 claw m2'. The upper boundary exists. From the comparison of Examples 3 and 4, and Comparative Example 5, the cutting area is about 0.040 mm2 is the upper limit for processing. Second, to manufacture 10 types of nibs that have the same end shape (Figure 16a) as the nib used in Example 1 but differ only in the length of the gap (GL). The trial will be 1.4 5 mm straight The spherical valve body is combined with the original pen of each nib, and the continuous inkjet experiment is used to compare the ink outflow. As a result, the ink outflow is significant when the gap length (GL) and the gap width (GW) are equal. It is also determined that the amount of ink flowing out when the length of the gap portion (GL) exceeds the width of the gap portion (GW) is: fixed. Therefore, the gap portion, that is, the length of the trench is preferably greater than the width of the trench. If the ease of processing is considered, the length of the trench and the The width of the trenches is slightly equal.
