Description

200800642 IX. Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a spreader for an aqueous steel ball pen or the like, and a spreader using such a sheet. [Prior Art]

": A coating tool having a steel ball at the front end, pressing the aforementioned steel ball, and applying the application liquid on the steel ball to the application object is known. And: the example of the application device is a steel ball using ink as an application liquid. For the ink, there are color materials such as dyes and pigments, and water is used as the water-based ink for the cold moon. The water-based steel ball pen with the ink is known. 3 As the ink, it is also known that water is used as the main solvent. Water-based colloidal ink. The steel sheet system for the steel ball pen is rotatably held in the body of the sheet. i, when the steel ball pen is used, the ink in the ink storage portion can be guided to the steel ball, and With the rotation of the steel ball, the ink is adhered to an object to be coated, such as paper. Such a steel ball pen and a steel ball pen piece are described in the patent documents, 2, etc. [Patent Document 1] JP-A-2005-186308 [Patent Literature] [2] Japanese Laid-Open Patent Publication No. 2-7-7876 [Problems to be Solved by the Invention] In an applicator such as a steel ball pen, in order to apply an ink or the like to the ink width of the application object, that is, the application width is reduced, Reduce the steel ball. In the case of such a smear, the opening of the steel ball accommodating chamber in which the steel ball can be accommodated and the opening of the front side of the smear can also become smaller as the size of the steel sister. 118372.doc 200800642 , therefore, because of the larger steel ball The flow of the coating liquid such as the gap between the steel ball and the steel ball containment chamber is changed [so the discharge of the application liquid is likely to be deteriorated. To prevent this '丨月形' from improving the flow of the application liquid as much as possible, so as to make the application liquid flow path In order to enlarge the flow path of the smear and improve the flow of the smear, it is necessary to use a structure that does not make the gap smaller than the other parts in a series of 歹Ik wipes. Therefore, By using the applicator having a large seat angle as shown in Patent Document 2, it is possible to enlarge the gap on the side of the front end opening while expanding the gap on the side of the side of the ball. Usually, when the applicator is used, the pressing force is applied to the object to be applied. The steel ball moves to the rear end side so as to be in circumferential contact with the seat surface of the steel ball accommodating chamber, and when applied, the pressing force of the self-applying object against the steel ball acts between the steel ball and the seat surface. Therefore, if the coating is continued The wiper will make the seat surface wear or squat, which will increase the axial movement of the steel ball. Especially if it is the same as the open shape, if the steel ball or steel ball containment chamber is small, the contact area will become smaller. Therefore, even under the same-pressing pressure, the surface pressure is increased, and the above phenomenon is apt to occur. Further, there is a type of applicator which performs a process of pressing the steel ball to the seat surface side at the time of manufacture, which is called a seat pressure. The steel ball can be moved axially, and the steel ball can be energized on the front end side. In the case of such a spreader, since the steel ball can be moved axially at the beginning, the axial movement of the steel ball is further increased once the seat surface is worn. If the axial movement amount of the steel ball is too large, the steel ball will excessively move to the rear end side during use, and the vicinity of the front end opening may be in contact with the application object during use, and it is difficult to perform the application under the falling state. I8372.d〇c 200800642 The groove of the ink groove near the surface is n | The gap of the knife is narrowed, and it is difficult to discharge the application liquid, which is not preferable. Therefore, the object of the present invention is to provide a sheet for a spreader and a spreader which are excellent in durability for continuously discharging the application liquid. [Summary of the Invention] [Technical means for solving the problem] In order to achieve the above object, the sheet for a gold wiper of the present invention includes a sheet body for a spreader and a sheet for holding a soil probe for coating a steel ball of less than 0.5 mm on the front end side of the body, characterized in that the body of the body of the smear-like smear is provided with a front end opening, a steel ball accommodating chamber, a central hole rear hole, and a connecting steel ball accommodating chamber and a central hole or a rear The groove or hole provided in the hole, the rear hole, the center hole, the steel ball receiving ... the end opening communicates to form a series of flow channels of the application liquid, and the steel ball receives the medium to the middle. Further, there are a seat surface and a side wall surface, so that the steel ball is rotatably held, and the connection surface between the seat surface and the side wall surface of the steel ball is connected to the seat surface, and the center of the body of the sheet body for the spreader is included.

According to the present invention, since the body of the sheet for the applicator and the steel ball of less than 0.5 are provided, the connecting surface between the seat surface and the side wall surface is provided on the steel ball accommodating chamber of the body body for the applicator, and the splicing surface is Since the seat angle is u or more, the gap between the flow paths of the application liquid can be ensured, and since the seat angle of the connection surface is 21 G or less, it is difficult to retreat the seat surface when the user is used, and the discharge of the application liquid can be stabilized. Also, the steel ball can be 0.35 mm or less. The structure of the crucible is 〇35 mm or less, so it is especially effective to smear the llB372.doc 200800642 liquid. Furthermore, the structure of the steel ball can be: a specific distance is moved. _ is only placed in the steel ball containment chamber by the second side of the steel ball. The straw is placed at the rear end of the steel ball, and the steel ball is energized toward the front end opening side. The steel ball forming member, ^ is based on this configuration, because the steel ball can only be set at a distance from the steel ball, and the lion is moved to the inner axial direction. The steel ball is placed on the rear side of the steel ball, and is given to the front end side. By arranging this component, the steel ball is used for this purpose, so that the usability can be ensured, and the main smear of the squirting liquid which is coated and dried can be prevented from being discharged when not in use. The seat surface can also be formed by deforming the steel ball from the front. In addition, ... 4 9 butterfly pressure seat pressure after the end deformation section 'by the seat of the factory to form a seat surface, thereby, =:: the front containment room can only move a certain distance.

Below 195, the 'replacement' angle is preferably and the 'joining surface is not connected to the side wall surface, and the joint surface and the side wall surface are hexagonal grooves. Further, the steel ball of the body of the applicator body can be formed by cutting the former or by cutting the juxtagonal groove at the front end of the cutting edge. Further, the applicator can be manufactured using the above-mentioned sheet for a spreader. [Effect of the Invention] In the sheet and the applicator for the gold wiper of the present invention, the discharge amount of the application liquid can be increased and the discharge can be continuously performed.

And, 'J ^-like installation There is a front end side of the ball pen to expose The outer bead pen piece-1' is mounted on the end side of the pre-test 7a with ink R, ', and inside the ink cartridge 6, filled with water-based ink or water-based porcine ink, that is, ink 5. 1 & Other types can be used, for example, oily 118372.doc 200800642 ink or oily gel ink can be used. 2 and 'Refill 7 is attached to a steel ball pen as shown in Fig. 1(b) It is used internally. It is implemented with the axis. The sorrowful sorrow is used by the front shackle 7a and the ballpoint pen 18 is written, and the ballpoint pen C: has the steel ball 10 pressed by one side. On the paper surface, etc., the steel is moved by the operation, and the steel ball can be rotated. The main smudge, that is, the ink 5, passes through the inside of the steel ball pen piece, and is attached to the steel ball 10 while flowing appropriately, and the writing is performed. In the field, the ink is placed at the rear end of the ink 5 in the ink cartridge 6 of the refill 7, and the ink is provided with the animal 8. Moreover, the ink can be used with the animal 8 to make the non-volatile or difficult-to-volatile organic liquid glue. Formed and formed by ink, with the animal 8, even in the ink 5 spit out In the case of a large one, it is also possible to follow. As shown in Fig. 2, the steel ball pen piece i is composed of a steel ball pen body (sheet for the applicator) 11, a steel ball 10, and a steel ball forming member 12. The front end side of the body body 11 is slightly conical, and the rear end side is slightly cylindrical in shape, and the overall appearance is rocket-shaped. Moreover, the front end side of the steel ball pen body body η has a conical portion 25 on the rear end side. The cylindrical portion 26 is provided. Further, the rear end side of the cylindrical portion 26 has an ink cartridge coupling step portion 26a whose outer diameter is slightly reduced, and the ink cartridge coupling step portion 26a is used for connection with the ink cartridge 6. Further, inside the steel ball pen body main body U, a steel ball accommodating chamber 15, a center hole 16, a rear hole 17, and a front end opening 14 are provided, and these are connected to each other to constitute a series of flow paths of the ink 5 (smear flow path). . Further, the rear end side of the rear hole 17 has a rear end side opening 28. -10-118372.doc 200800642 As shown in FIG. 3 and FIG. 4, the steel ball accommodating chamber 15 has a side wall surface 41 which is a side wall of a cylindrical inner shape, and a seat surface Μ and a connecting surface 7 which are located at the rear end side of the side wall surface 41. The surface 71 is located between the side wall surface 41 and the seating surface 45 and is a surface that is connected to the seating surface. The seat surface 45 is formed by a seat on which the steel ball 1〇 is in contact with each other, and is formed by pressing the steel ball 10 from the front end side to the rear end side as described later, and has a circular arc shape in cross section. 3. Since the seat surface 45 is formed by a seat press, the seat surface 45 and the joint surface 71 are different from each other. When the seat surface 45 is not formed, the seat surface 45 and the joint surface 71 are flush with each other. As shown in Fig. 3(a), the shape of the joint surface 71 is a flat shape, and is a corner constituting the joint surface 71 of the cross section including the center axis. The angle of the front end side of the cross section, that is, the seat angle cx is 180. . Further, the connecting surface 71 may have a shape other than a plane, that is, a conical shape, but the seating angle α ranges from 15 〇. ~2ι〇. It should be 165 ° ~ 195 °, more preferably 170. ~190. . In addition, if the seat angle α is larger than the angle, the seat surface 45 is pressed by the steel ball 1〇 during use, and the deformation or wear of the seat surface 45 is easily generated, and the seat surface is easily retracted, and if the seat angle α is smaller than the angle, Since the gap 后 which will be described later becomes small and it is difficult to supply the ink 5, the above range is preferable. Further, as shown in Figs. 3 and 4, a groove 47 called an arrow-shaped groove is radially provided around the center hole 16 of the body of the ball-point pen body. Further, the groove 47 is connected to the side of the steel ball accommodating chamber 15, and the ink 5 enters the groove 47 from the center hole 16, and is further passed through the outlet portion 61 (gap Τ) on the side of the steel ball accommodating chamber 15 of the groove 47, in the steel ball accommodating chamber 15 Side out. Further, in the present embodiment, three grooves 47 are provided. As shown in Fig. 2, the steel ball forming member 12 is provided with a coil spring which is energized to produce a portion 22 and a rod portion 23. Further, the steel ball forming member 12 is disposed on the rear end side of the steel ball 10, and the front end 23& of the rod-shaped portion 23 of the steel ball forming member 12 is in contact with the steel ball 10 to impart the steel ball 10 to the front end opening 14 side.

The steel ball forming member 12 is disposed inside the body of the steel ball pen body. 2, the steel ball forming member 12 is in a compressed state, and the steel ball forming member 12 is energized to the end side. Therefore, in the case where the steel ball pen 18 is not used, the steel ball 10 blocks the front end opening 14 of the front end side of the steel ball accommodating chamber 15 by the above-described energization to prevent the ink 5 from flowing out to the outside, and when the steel ball pen '1 8 is used, By the pressure of writing, the steel ball 1 is moved to the rear end, and a gap is formed between the steel ball 1〇 and the steel ball accommodating chamber 15, so that the ink 5 is easily discharged. The shape of the steel ball 10 is spherical. Further, as shown in Fig. 3, the steel ball 1 is housed in the steel ball storage chamber 15, and is rotatably held in the steel ball storage chamber 15 of the steel ball piece body. That is, the end side of the steel ball 1 is held by the seat surface 45, and the side surface side of the steel ball 1 is held by the side wall surface 41, and the front end side of the steel ball 10 is held by the end deformation portion 43. The distal end deforming portion 43 is a portion that is deformed by deforming the front end of the steel ball pen body U toward the inner side after the steel ball 1 is inserted, thereby preventing the steel ball 10 from being detached from the front end side. Mm, less than 0.3 5 mm, smaller. Further, the steel ball The outer diameter of the steel ball 1 本 of the present embodiment is 〇·3. It is used in a normal steel ball pen or the like. 10 It is also possible to use an outer diameter of more than 〇·35 mm and less than 0.5 mm. Next, the manufacturing method of the steel ball pen piece 1 will be described. First, the processing of the Beth steel ball pen body 11 is processed. Specifically, the cylindrical material is cut into a specific shape, and by this cutting, the steel ball accommodating chamber 15, the center hole 16, the rear hole 17, the front end opening 14, and the groove 47 are formed inside. This 118372.doc -12- 200800642 is a portion of the steel ball accommodating chamber 15 which is formed as a seating surface 45 and a connecting surface 71 which is formed to be perpendicular to the axial direction. Further, the steel ball 10 is housed in the steel ball accommodating chamber 15, and is caulked so that the end portion on the side of the front end opening 14 is deformed by the steel ball i, and the front end deformation portion is formed, and then the seat pressure is pressed to press the steel ball to the rear end side. The front end opening 14 is formed to complete the steel ball pen piece 1.

As shown in Fig. 3, the position of the steel ball 1〇 before the seat pressure is the position of the imaginary line, and the steel ball 10 is moved to the rear end side only by the seat pressure, and is formed in the vicinity of the front end deformation portion 43. The gap S1 forms a seating surface 45 on the other side. Further, the shape of the seat surface 45 is in a shape that matches the surface of the steel ball 1〇. Moreover, by the seat pressure, the steel ball 10 can only axially move the seat deformation distance. The distance between the seat deformation amount L is usually 10 to 2 〇μπι. In the steel ball pen piece 1 made of the above, the steel ball forming member 12 is energized to the front end side of the steel ball 10, as shown in Fig. 1(b). Install the ink cartridge 6 and fill the ink ^ to complete the pen holder 7. Further, as shown in Fig. 1(b), the ballpoint pen 18 is completed by loading the refill 7 into the barrel 19. When it is used for writing or the like, since the steel ball 1〇 is pressed from the front end side to the seat surface 45 side by checking the pressure of the Tian Lingma, the steel ball 1〇 碉砵(3) contacts the seat surface 45. Further, in the case where it is not used, the steel ball 10 is energized, and the steel ball 10 is moved toward the front end side to come into contact with the front end deformation portion 43. The sheet 1 can secure the ink. As will be described later, the flow path of the steel ball pen water 5 of the present embodiment can achieve excellent durability. Gap As shown in Fig. 3 (a), the steel ball τ, the gap S1, and the gap S2 in the present embodiment. The gap between the side wall surface 41 of the steel ball accommodating chamber 15 and the side of the steel ball 10 is formed in the gap between the side wall surface 41 of the steel ball accommodating chamber 15 and the steel ball 10 in the vicinity of the outlet portion 61, 118372.doc 13 200800642. The clearance S1 is a gap between the vicinity of the front end deformation portion 43 of the front end side of the ball-point pen body body and the steel ball 1 〇. And in the case of using the steel ball pen 8 , as shown in the graph of FIG. 4 , the application liquid, that is, the ink 5 passes through the gap τ of the outlet portion 6 1 of the groove 47 on the side of the ball receiving chamber 15 of the groove 47, in the steel ball The accommodating chamber 15 flows out and flows out from the gap S1 to the outside through the gap S2.

The gap Τ, the gap S1, and the gap S2 are determined by the outer diameter 钢 of the steel ball 1〇, the steel ball movement amount P, and the inner diameter of the side wall surface 41 of the steel ball accommodating chamber 15. Further, the steel ball movement amount P is substantially equal to the seat pressure deformation amount L in the initial state. Further, when the ball point pen 18 is used, the seat surface 45 is worn or deformed, and the steel ball 1 〇 sinks, and the steel ball movement amount P increases. At this time, the area of the seat surface 45 is increased, and the area of the joint surface 7! is reduced, and the outermost portion of the portion where the steel ball 1 is in contact with the seat surface 45 is moved outward. Further, in the steel ballpoint pen 18 of the present embodiment, even if the steel ball is moved in the initial state, the gaps T, s1, and S2 can be secured, and the wear or deformation of the seat surface 45 can be reduced. The change of the gaps T, S1, and S2 is as follows: The outer diameter of the steel ball is 〇.3 mm, the inner diameter of the steel ball accommodating chamber 15 is 〇33 mm, and the internal control of the rear hole is 〇15 coffee, as shown in Fig. 5 and 6. The seating angle & shown in Figure 7 is 12 inches. The ballpoint pen body 100 and the seat angle are 18 inches. ># U ^ ! 仏 仏 压 α α α α α 180 180 180 180 180 α α α α α α α α α α α α α α α α α α α α α α In addition, the change of the moving amount ρ of the Wangang bead and the relationship between the gap-seeing I-view and the area 辔〆μ7, confirming the movement amount ρ of the steel ball, and the distance of the second moving ρ due to the seat pressure, the wear of the seat surface 45, etc. 118372 .doc -14- 200800642 and changes in the situation of change. Changing the amount of movement of the steel ball p shows that the curve of the product between the gaps t, S1, and S2 is as shown in the figure. In addition, in the three cases where the seat angle α is different, the width of the gap τ varies, so the gap is different. The area of the gap is also changed, but the width near the gaps s 1 and S2 is independent of the angle or shape of the seating surface 45, the yoke 2, and the ^ ^ ^ 5 埂 joint 71, so the gap S 1 , S2 near the surface selection + # &. < The area of the welcome is exactly the same between the three types. Also, the width of the gap S2 and the amount of movement of the steel ball, ,,, off, a certain value, Therefore, the area near the gap S2 is also constant. In the case of Figure 8, the seat angle °" is 180 〇 in the case of 120 〇, even if the steel ball movement amount Ρ ^, it can ensure the vicinity of the gap Τ Since the gap area is provided, the ink in the filler can be stably supplied. For example, the seat pressure movement amount 1 is 2 〇μηι (the amount of movement of the steel ball is 2 〇 (4), 2 the amount of movement of the steel ball ρ is increased by 2G by use. In the case of μηι (the distance between the steel ball and the Ρ Ρ 〇 is 4 〇 Τ) Τ ^ Π 1 The gap area of the system, the seat angle α is 180〇 About 3 times. For the above three types, the contact area of the seat surface 45 has been confirmed. Since the contact area of the main surface 45 varies depending on the amount of movement of the steel ball ρ, the contact area of the seat surface 45 and the steel ball have been investigated. The relationship between the movement amount ρ. The result is as shown in Fig. 5(b), (c), Fig. 6(b), (c), Fig. 7(8), (4).

Regarding the difference between the writing amount and the amount of movement of the steel ball ρ, the difference in the private degree of the force, respectively, changes the seat angle α, and the same conditions continue to test the movement of the respective balls. Further, the difference in the degree of increase in the amount of movement of the steel ball ρ by the writing is that the writing load is 〇. Jane (1〇〇 gf), and the inclination angle at the time of writing (the angle with the writing object: the line) is 65. Write speed is 7 cm / sec, continuous writing under the condition of pressure of 98.98N (100 gf), check the distance that can be written, and confirm the effective writing distance (can keep 5 〇 per 100 m) distance). In addition, regarding the writing durability, the seat pressure deformation amount L: 汕 μηι is used. The results are shown in Figures 9 to 11 . In addition, the vertical axis of the punching port of Fig. J is the ink outflow 118372.doc -16- 200800642. The weight is confirmed every 100 m, and the reduction is confirmed. The graph shows the degree of susceptibility to deformation or wear. Yahe, in the seating angles c^120〇, 15〇〇, 18〇〇 and 21〇〇, the change of the momentum P of the steel ball ( (the amount of steel ball sinking) is almost the same, but at the seat angle...

Among them, the difference is particularly large, and the seat angle ^ 24() is known. Compared with others, it is more prone to deformation or wear. / Fig. 10 is a graph showing the relationship between the writing distance and the ink outflow amount in changing the seat angle α. X, _ shows a graph of the relationship between the seat angle α and the effective writing distance. As shown in Figs. 10 and 11, the writing durability is different depending on the seating angle α. Further, as shown in Fig. 7, the writing distance is shortened regardless of whether the seat angle is too small or the seat angle α is too large. This can be considered as the following reasons.

Quantity, the weight in this confirmation. When the seat angle α is smaller and the seat angle is larger than that of the larger one, the amount of ink flowing out becomes smaller in the case where the amount of movement of the steel ball is increased. Therefore, as the writing and wear continue to increase the amount of movement of the steel ball, the ink outflow starts to decrease as soon as possible. In addition, the case where the seat angle α is larger in the same steel ball movement amount ρ

Qiao ~ Bu, than the seat angle (X small seat surface 45 is small (Figure 5 ~ Figure 7). Moreover, the area of the seat surface 45 is basically proportional to the square of the outer diameter of the steel ball 10, so in the steel ball 1 In the case of a smaller outer diameter of 0·3 mm or less (less than 〇·5 mm), the area of the seat surface 45 is particularly small. Therefore, when used, it acts on the seat surface 118372.d. 〇c -17- 200800642 45 The fabric is large, and the seat surface 45 is weak q fast. As a result, the steel ball moves compared with the seat angle α, and if the steel ball moves too long, the gap is small. The area of the ink becomes smaller, and the outflow of the ink becomes worse. When used, the front end opening of the body of the steel ball pen body η protrudes by 4 4 _, Λ \ ^ The part of the steel ball 10 which is large is too small, so In the case of the outer diameter of the steel ball 10, such as the outer diameter of 3 mm, etc., the mouth L of less than 35 coffee (less than two) is relatively small, and the seat angle is 15 〇 to 21 〇.

In the above-mentioned steel ball piece 1 , the ink ejected by the corpse 5 is an aqueous ink or a water-based gel ink, but may also be a pot, the other, For example, oily ink, correction fluid (aqueous, oily), etc. Further, if the outer diameter of the steel ball 10 is small, it is a structure other than the body. It is also applicable to the above-mentioned steel ball pen piece: the connection surface 71 of the above embodiment is located on the side Between the wall surface 41 and the seat surface 45, the wall surface 41 and the seat surface 45 are connected to each other. However, if the seat surface 45 is connected to the connection surface 71, the connection surface 71 can be separated from the side, and the soil 1 can be separated. A gap or the like may be formed between the side faces 41 of the connecting faces. For example, the steel ball #7m shown in Fig. 12 and Fig. 13 may be connected to the side wall surface 41 by the connecting surface 71.
