As Fig. 1 (a) (b) shown in, the ball pen tip of first embodiment of the present invention (spreading implement tip) the 1st, the ball pen tip that in ball pen (spreading implement) 18, uses, particularly, in ball pen 18, use core 7, ball pen tip 1 is installed at the front end of core 7.In addition, shown in Fig. 1 (b), core 7 is provided with protecgulum 7a and ink tube (coating fluid containing section) 6.Ball pen tip 1 is installed in front end one side of protecgulum 7a, externally exposes, and in the rear end side of protecgulum 7a ink tube 6 is installed.Be filled with ink 5 as water-base ink or aqueous gel ink in the inside of ink tube 6.
In addition, the kind of ink 5 can be used the ink of other kinds, for example, can use oily ink or oil-base gel ink.
And for example shown in Fig. 1 (b), core 7 be installed in ball pen (spreading implement) 18 beam barrel 19 inside and be used.With the installation of this beam barrel 19 by fixedly carrying out with protecgulum 7a.
Under the situation of using ball pen 18 to take down notes, the ball 10 that the front end of ball pen tip 1 is had is pressed on the paper etc., is undertaken by mobile ball pen 18.By this operation, swing roller 10, as the ink 5 of the coating fluid inside by ball pen tip 1, suitable amount can be taken down notes attached on the ball 10 and flow out.
And the rear end of the ink 5 in the ink tube 6 of core 7 is provided with ink follower 8.This ink follower 8 can use by making fixedness or difficult volatile organic liquid material become the structure that the gelation thing constitutes, and under the big situation of the output quantity of ink 5, utilizes ink follower 8 to stablize and appends.
As shown in Figure 2, ball pen tip 1 is by ball pen tip body (spreading implement tip body) 11, and ball 10 and ball force application part 12 constitute.
The profile of ball pen tip body 11 its front end one sides is roughly taper shape, and the profile of rear end one side is roughly cylindrical, and overall appearance is the rocket shape.Front at ball pen tip body 11 has conus portion 25, and one side has cylindrical portion 26 in the rear end.And rear end one side of cylindrical portion 26 has the diminishing ink tube of external diameter in conjunction with stage portion 26a.Ink tube is connected use in conjunction with stage portion 26a with ink tube 6.In addition, be provided with ball cover 15 in the inboard of ball pen tip body 11, centre bore 16, dorsal pore 17, front opening 14, they are communicated with, and become a succession of stream (coating fluid stream) of ink 5.And the rear end side of dorsal pore 17 has rear end side opening 28.
As shown in Figure 3 and Figure 4, ball cover 15 has as the side wall surface 41 that makes the sidewall of cylinder interior shape, is positioned at the bearing-surface 45 and the joint face 71 of the rear end side of side wall surface 41.Joint face 71 is between side wall surface 41 and bearing-surface 45, the face that is connected with bearing-surface 45.The face that bearing-surface 45 contacts with ball 10 when using, as described later, by with ball 10 from the front side wedge of the pushing formation of pushing to the back-end, its cross sectional shape is circular-arc.Because bearing-surface 45 utilizes the method for wedge to form, so bearing-surface 45 is different faces with joint face 71, do not carrying out under the situation of wedge, and bearing-surface 45 is identical face with joint face 71.
Shown in Fig. 3 (a), being shaped as of joint face 71 is plane, in the cross section on comprising the face of central shaft, and the angle of the front in the cross section of the angle that forms as joint face 71, promptly bearing angle α is 180 °.In addition, joint face 71 is that the taper shape of the shape beyond the plane is also passable, and the scope of bearing angle α is 150 °～210 °, is preferably 165 °～195 °, more preferably 170 °～190 °.
When bearing angle α is bigger than this angle, during use etc., push down bearing-surface 45 by ball 10, bearing-surface 45 is easy to generate distortion or abrasion, and bearing-surface 45 retreats easily.In addition, when bearing angle α than this angle hour, slit T described later is little, ink 5 is difficult to supply with, therefore preferably in above-mentioned scope.
And for example Fig. 3 is shown in Figure 4, is the radial groove 47 that is called so-called pointer groove that is provided with around the centre bore 16 of ball pen tip body 11.And groove 47 is connected with ball cover 15 sides, and ink 5 can pass through the export department 61 (slit T) of ball cover 15 sides of groove 47 again from centre bore 16 lead-in grooves 47, flow out to ball cover 15 sides.In the present embodiment, be provided with groove 47 three positions.
As shown in Figure 2, in ball force application part 12, be provided with the application of force generating unit 22 of spiral spring and bar-shaped 23.Ball force application part 12 is configured in rear end one side of ball 10, and bar-shaped 23 front end 23a of ball force application part 12 contacts with ball 10, and ball 10 application of forces are pressed in front opening 14 sides.
Ball force application part 12 is located at the inside of ball pen tip body 11.Ball force application part 12 is a compressive state, utilizes ball force application part 12, with ball 10 towards the front application of force.Thus, under the situation of not using ball pen 18, utilize the above-mentioned application of force, ball 10 clogs the front opening 14 of the front of ball cover 15, can prevent that ink 5 from flowing out to the outside.When using ball pen 18, by the notes pressure ball 10 is moved to the back-end, the slit appears between ball 10 and ball cover 15, and ink 5 is flowed out easily.
The external diameter of the ball 10 of present embodiment is 0.3mm, below 0.35mm, in using, uses smaller ball in common ball pen etc.Ball 10 also can use external diameter bigger than 0.35mm, but less than the ball of 0.5mm.
Secondly, the manufacture method of ball pen tip 1 is described.
At first, carry out the processing of ball pen tip body 11.Particularly, cut the material of garden cylindricality, make the shape of regulation, form ball cover 15, centre bore 16, dorsal pore 17, front opening 14 and groove 47 in the inboard by cutting.At this moment, process bearing-surface 45 that makes ball cover 15 and the part that constitutes joint face 71, become and axial vertical plane.
Again ball 10 is accommodated in the ball cover 15, rivets, make the end of front opening 14 sides be pressed on the ball 10 and be out of shape, form front end variant part 43.Then, ball 10 is pressed to rear end side, carry out wedge, form front opening 14, finish ball pen tip 1.
As shown in Figure 3, the position of the ball 10 before carrying out wedge is the position of imaginary line, and by wedge, in rear end side, only movement and deformation amount L forms slit S1 near front end variant part 43, on the other hand, forms bearing-surface 45 by wedge for ball 10.And, bearing-surface 45 be shaped as surperficial consistent shape with ball 10.
By wedge, ball 10 can axially only move the distance of a wedge deflection L.Usually, the distance of this wedge deflection L is 10～20 μ m.
Ball force application part 12 is installed on the ball pen tip of making as mentioned above 1, to the front application of force of ball 10, shown in Fig. 1 (b), ink tube 6 is installed, filling ink 5 is finished core 7.And for example shown in Fig. 1 (b),, finish ball pen 18 by core 7 is inserted in the beam barrel 19.
When using in when notes etc., utilize pen to press and make ball 10 press to bearing-surface 45 sides from front, ball 10 contacts with bearing-surface 45.And under obsolete situation, ball force application part 12 makes ball 10 forward end side shiftings, contacts with front end variant part 43.
As described later, the ball pen tip 1 of present embodiment can be guaranteed the stream of ink 5, good endurance.
Shown in Fig. 3 (a), in the ball pen tip 1 of present embodiment, form slit T, slit S2, slit S1.Slit T is near the slit of the ball 10 the export department 61 with groove 47, slit S2 is near the slits of side wall surface 41 and the ball 10 of ball cover 15 immediate, and slit S1 be the slit with near the ball 10 of the front end variant part 43 of the front of ball pen tip body 11.
Shown in the curve of Fig. 4, using under the situation of ball pen 18, from centre bore 16, the slit T of the export department 61 of ball cover 15 1 sides by groove 47 flows out to ball cover 15 as the ink 5 of coating fluid, and through slit S2, S1 flows out to the outside from the slit again.
Slit T, slit S1, slit S2 is by the decisions such as internal diameter of the side wall surface 41 of the amount of movement P of the outer diameter D of ball 10 or ball or ball cover 15.The amount of movement P of ball, state is substantially equal to the deflection L of wedge in the early stage.
In addition, when using ball pen 18, bearing-surface 45 wearing and tearing or distortion.Ball 10 is sunk, and ball amount of movement P increases.At this moment, the area of bearing-surface 45 is big, and the area of joint face 71 is little, and the outermost part of the part that contacts with the bearing-surface 45 of ball 10 moves more laterally.
Utilize the ball pen 18 of present embodiment,, when ball amount of movement P is big, also can guarantee above-mentioned slit T, S1, S2 even in the early stage under the state; And can reduce the wearing and tearing or the distortion of bearing-surface 45.
Distortion as this slit of following affirmation T, S1, S2.
As Fig. 5, Fig. 6, shown in Figure 7, the external diameter of getting ball 10 is 0.3mm, the internal diameter of ball cover 15 is 0.33mm, the internal diameter of dorsal pore is 0.15mm, and preparing bearing angle α is 120 ° ball pen tip 100, the ball pen tip 1 that bearing angle α is 180 °, 101 3 kinds of ball pen tips of ball pen tip that bearing angle α is 240 °.Variation when variation and slit T, S1, the width of S2 or the relation of area change of research ball amount of movement P, confirm because the wearing and tearing of wedge or bearing-surface 45 etc. make the variable in distance of ball amount of movement P.
Fig. 8 represents to change ball amount of movement P, the curve map of the slit area of slit T, S1, S2.
In addition, because the width of slit T is three kinds of different different in width of bearing angle α, though the area of slit T is along with the wide variety of slit T, near but the width slit S1, the S2, it doesn't matter with angle, the shape of bearing-surface 45 and joint face 71, so near three kinds of areas slit S1, the S2 are identical.And the width of slit S2 and ball amount of movement P are irrelevant, are definite value, so near the area the S2 of slit is certain.
As shown in Figure 8, with bearing angle α be that bearing angle α is 180 ° a ball pen tip, and is big even ball amount of movement P becomes under 120 ° the ball pen tip situation relatively, also can guarantee near the slit area that slit T is, therefore can be stably with in the providing ink refill for ball-point pen.
For example, when to pressure seat amount of movement L being 20 μ m (ball amount of movement P is 20 μ m), because when using the slit area of the slit T under the state of the situation (ball amount of movement P is 40 μ m) again ball amount of movement P is increased by 20 μ m to compare, bearing angle α is that 180 ° ball pen tip and bearing angle α is that 120 ° ball pen tip is compared and is about 3 times.
In addition, confirm the contact area of the bearing-surface 45 of above-mentioned three kinds of ball pen tips.Since the contact area and the ball amount of movement P respective change of bearing-surface 45, the contact area of research bearing-surface 45 and the relation of ball amount of movement P.The results are shown in table 1.At Fig. 5 (b), (c), be illustrated respectively in three kinds of ball pen tips among Fig. 6 (b), (c), Fig. 7 (b), (c), ball amount of movement P is 20 μ m, the bearing-surface 45 during 40 μ m.
Table 1
Area (the mm of bearing-surface
2)
| Ball amount of movement P | Bearing angle | ||
| 120° | 180° | 240° | |
| 20μm | 0.0232 | 0.0104 | 0.0054 |

As shown in table 1, be that 120 ° ball pen tip is compared with bearing angle α, bearing angle α is that the contact area of bearing-surface 45 of 180 ° ball pen tip and ball 10 is little, writes smoothly.
In addition, in order to confirm bearing angle α, confirm to cause degree that the amount of movement P of ball increases not simultaneously, the difference of the outflow variation of the ink that notes cause when notes to Effect on Performance.This confirms also to add up to 5 kinds of ball pen tips to confirm to 150 °, 210 ° except above-mentioned bearing angle α is 120 °, 180 °, 240 ° ball pen tip.
The difference of the increase degree of the ball amount of movement P that notes cause can change bearing angle α respectively, takes down notes the variation of research ball amount of movement P separately under identical condition continuously.
In addition, the difference of the degree that the ball amount of movement P that causes about notes increases, be 0.98N (100gf) at the notes load, inclination angle during notes (with the angle of the normal of taking down notes object) is 65 °, and notes speed is 7cm/ second, and pressing force is under the condition of 0.98N (100gf), take down notes continuously, research can be carried out the notes of much distances, the notes distance that efficiency confirmed (every 100m can keep the distance that the above ink of 50mg flows out).Wherein, carrying out wedge deflection L about the research use of carrying out writing durability is the ball pen of the wedge of 20 μ m.
The result is illustrated among Fig. 9～Figure 11.The longitudinal axis of Figure 10 is the ink discharge.This confirms as the weight of confirming every 100m, utilizes the weight that reduces to confirm.
The result's that the increase degree of the ball amount of movement P that Fig. 9 causes for expression notes is different curve map, the easiness that expression distortion or wearing and tearing take place.
At bearing angle α is in the ball pen tip of 120 °, 150 °, 180 ° and 210 °, the variation of ball amount of movement P (ball deflection) does not almost have difference, but at bearing angle α is big especially in 240 ° the ball pen tip, therefore can find out, compare with other ball pen tips, bearing angle α is that 240 ° tip deforms easily or weares and teares.
When Figure 10 changes bearing angle α for expression, the curve map of the relation of notes distance and ink discharge.Figure 11 is the curve map of the relation of expression bearing angle α and effective notes distance.
As Figure 10, shown in Figure 11, about writing durability, because of bearing angle α difference, the distance that can take down notes is different.And for example shown in Figure 11, bearing angle α is too small, and bearing angle α is excessive, and the distance that can allow to take down notes shortens.
Think based on following reason.
The ball pen tip that the little ball pen tip of bearing angle α and bearing angle α are big is compared, and ball amount of movement P becomes under the big situation, and the ink discharge is little.Therefore, proceed notes, under the situation of ball amount of movement P because of same increases such as wearing and tearing, the ink discharge begins rapidly to reduce the state that very fast generation can not be taken down notes.
In addition, under the situation of identical ball amount of movement P, the ball pen tip that the big ball pen tip of bearing angle α and bearing angle α are little is compared, the 45 little (Fig. 5～Fig. 7) of bearing-surface.Because the area of bearing-surface 45 approximately and square proportional variation of the external diameter of ball 10, be that the area of bearing-surface 45 is especially little under the smaller situation of (less than 0.5mm) below the 0.35mm of 0.3mm etc. at the external diameter of ball 10.Therefore, the surface pressing that acts on during use on the bearing-surface 45 becomes big, and perhaps bearing-surface 45 weakens distortion easily, and wearing and tearing are comparatively fast carried out.As a result, the ball pen tip little with bearing angle α compares, and it is big that ball amount of movement P becomes easily.
When ball amount of movement P was long, the area of slit T reduced, and it is bad that ink flows out, and the part of the ball 10 that stretches out from the front opening 14 of ball pen tip body 11 during use is too small, can not take down notes.
Like this, be under the situation of (less than 0.5mm) below the 0.35mm of 0.3mm etc. smaller diameter at the external diameter of ball 10, about performances such as ink outflow property or writing durability, the ball pen tip that bearing angle α enters 150 °～210 ° of scopes liken to into the ball-point pen tip of 120 ° beyond this scope or 240 ° first-class good, therefore, by making bearing angle α in this scope, can provide good ball pen tip (spreading implement tip) 1.
In above-mentioned ball pen tip 1, the ink 5 of output is water-base ink or aqueous gel ink, but other inks also can, for example oily ink or opaquing fluid (water-based, oiliness) etc. also can.
In addition, if the external diameter of ball 10 is little, then can be suitable in the structure beyond above-mentioned ball pen tip 1.
The joint face 71 of above-mentioned embodiment is between side wall surface 41 and bearing-surface 45, with any is connected in side wall surface 41 and the bearing-surface 45, if but bearing-surface 45 is connected with joint face 71, then joint face 71 and side wall surface 41 leave also passablely, form slit etc. and also can between joint face 71 and side wall surface 41.
For example, as Figure 12, ball pen tip 2 shown in Figure 13, joint face 71 is not connected with side wall surface 41, adopts in the outside of joint face 71, promptly forms the structure of cannelure 60 on the inside part of side wall surface 41.Forming under the situation of this cannelure 60, above-mentionedly adding man-hour, the free degree of processing is big, can make the handling ease of ball pen tip body 11.Particularly, utilizing under the situation of cutting the ball cover 15 that forms ball pen tip body 11 continuously, corresponding by making with cannelure 60 by the part of the front end of bite cutting, the dimensional accuracy of cannelures such as joint face 71 or side wall surface 41 60 other parts in addition can be kept, and the more processing of the ball pen tip body 11 of more number can be carried out.
In addition, under the situation of this ball pen tip 2, when according to operating position, when ball 10 sinks, partly surpass joint face 71 with the outermost of the contact portion of the bearing-surface 45 of ball 10, in use might become does not have joint face 71.Therefore, when not having joint face 71, be difficult to keep above-mentioned performance when in use becoming.
In addition, under the situation of the structure that the joint face 71 that adopts ball pen tip 2 and side wall surface 41 leave, preferably increase joint face 71 to a certain extent, position (Figure 12 of ball 10 in feasible the use, the imaginary line position of Figure 13) on, the outermost peripheral part X1 of the part that contacts with the bearing-surface 45 of ball 10 becomes the inboard of the outer peripheral portion X2 of joint face 71.
Particularly, the decrease m1 of the size M of preferred ball 10 is the outer peripheral portion X1 of the contact portion of ball 10 under 20% the state of outer diameter D of ball 10 and bearing-surface 45, and the inboard for the outer peripheral portion X2 of joint face 71 is the inboard of cannelure 60.In this case, even be that joint face 71 becomes remaining state under 20% the situation of outer diameter D of ball 10 at the decrease m1 of the size M of ball 10.
Also preferred, the decrease m1 of the size M of ball 10 is that the outer peripheral portion X1 of the contact portion of ball 10 and bearing-surface 45 is the inboard of the outer peripheral portion X2 of joint face 71, is the inboard of cannelure 60 under 30% the state of outer diameter D of ball 10.In this case, even be that joint face 71 is remaining state under 30% the situation of outer diameter D of ball 10 at the decrease m1 of the size M of ball 10.
Like this, though the ball pen tip 2 that uses joint face 71 and side wall surface 41 to leave, also can with the above-mentioned ball pen tip 1 same ball pen tip that forms good endurance.
