But, in ballpoint tip 1 of the present invention, because the pressurizing and deformation surface portion 70 of ballpoint tip main body 11 is processed into the part of summit as the cone surface of front, even press pearl deflection L to increase thus, but because bearing surface front end side edge part 54 is in the inboard, so the gap T of the export department 61 of pearl pedestal 15 sides of groove 47 can become bigger.Therefore the discharge of having stated ink 5 of the present invention can be at least 100mg/10m, can also flow out more ink 5.Thereby, when writing with it, the person's handwriting that can form surfacing and have the glossy three-dimensional.
In addition, the influence of pressurized pearl deflection L is very little, near side wall surface 41 and the ball 10 the most approaching places gap S2 is made into the certain-length less than gap S1 and gap T, owing to can reduce the circulation of ink 5 most effectively by gap S2, so can positively realize adjustment to flow.That is, a present tool because gap S1 and gap T can not become greatly simultaneously, therefore as utilizing gap S2 that flow is reduced, just must make S2 narrower, so just can not flow out more coating fluid.In addition, as utilize gap S1 and gap T to adjust flow, then can cause fluctuations in discharge, thereby can not realize stable the adjustment owing to the deviation of pressure pearl deflection L.But, pearl pedestal 1 of the present invention, because gap S1 and gap T can become big simultaneously, and can adjust flow by gap S2, therefore also applicable to a tool that flows out more coating fluid, and the discharge of having stated ink 5 of the present invention can be at least 100mg/10m, thereby when writing with it, the person's handwriting that can form surfacing and have the glossy three-dimensional.
Also have, as shown in Figure 6, bearing surface side machined surface 48 comprises pressurizing and deformation surface portion 70 and linking part 71, and this pressurization sex change surface element 70 deforms by pressing pearl.As shown in Figure 6, by the pressure pearl, the pressure that pressurization sex change surface element 70 is subjected to from ball 10, deforming becomes bearing surface 45.
The shape of bearing surface side machined surface 48 is to be the lateral shape of the frustum of a cone of front with the summit, is the part of cone surface.In addition, pressurization sex change surface element 70 and linking part 71 are to be the shape of the circular cone table top of front with the summit too, are the parts of cone surface.Crimp surface element 70 forward end are side-prominent.The cross section angle [alpha] of the front of this frustum of a cone is 240 °, and the medial surface 48a of bearing surface side machined surface 48 is acute angle-shaped.
In addition, in the bearing surface side machined surface 48 of present embodiment, the integral body of pressurizing and deformation surface element 70 forms summit the 1st 85 as the cone surface of front.In addition, because linking part 71 is the parts of not carrying out pressing the pearl distortion, so it is non-pressurizing and deformation surface element 72.
There is no particular limitation for the manufacture method of a tool like this, but be preferably the assemble method of following ballpoint tip 1.
For example, at first form ballpoint tip main body 11.Use columned material, on the profile front side is processed into the conus portion 25 of nearly cone shape, form designated shape (the 1st operation).Then, the structure with a side wall surface of inwall shape and bearing surface side machined surface 48 is processed in the inboard of the pearl pedestal 15 of nib main body 11, bearing surface side machined surface 48 is formed on from the centre hole side edge of above-mentioned side wall surface to an axle central side, and is connected with centre hole 16.Particularly in the part that forms above-mentioned pressurizing and deformation surface portion 70, be processed into and be provided with the structure of the part of distolateral protrusion (the 2nd operation) forward.Follow again, form groove 47 processing ballpoint tip main bodys 11 (the 3rd operations).Then, place ball 10 in pearl pedestal 15, the front end that makes nib main body 11 is to ball 10 sides distortion (the 4th operation).At last, above-mentioned ball 10 is pressed to centre hole 16 sides from front end, make pressurizing and deformation surface element 70 distortion formation bearing surfaces 45 (the 5th operation) as the part of above-mentioned bearing surface side machined surface 48.
In addition for example, in above-mentioned the 2nd operation, can adopt the part that will form above-mentioned pressurizing and deformation surface portion 70 to be processed into to be provided with frustum of a cone side view the 1st, the summit of this frustum of a cone replaces in the part that forms above-mentioned pressurizing and deformation surface portion 70 as the method for a tool with the front end of point, is processed into the method for the structure that is provided with forward end bulge branch.
Because ink flowrate of the present invention is more, the front end variant part 43 of the front end of above-mentioned ballpoint tip main body 11 can adopt the formation of the 2nd mode as shown in Figure 7.
Promptly, as shown in Figure 7, the structure of this ballpoint pen is that the outer shape of nib main body 11 is for closely coniform, it is ringent pearl pedestal 15 that the inboard of this nib main body 11 has front end, ball 10 places in above-mentioned pearl pedestal 15 and ball and can have the front end that makes above-mentioned nib main body 11 and be out of shape and the front end variant part 43 of formation to ball 10 sides at a certain distance along moving axially in above-mentioned pearl pedestal;
The front end variant part 43 of above-mentioned nib main body 11 has the Outboard Sections 55 that is cut circlewise, and this Outboard Sections and inside part are out of shape to ball 10 sides together.
In addition, as Fig. 7, around the centre hole 16 of ball-point pen tip main body 11, be radial being provided with and be called as the groove 47 of vowing groove.This groove 47 is connected with pearl pedestal 15, and ink 5 can be from centre hole 16 by groove 47, and the export department 61 of pearl pedestal 15 sides of the groove 47 of flowing through flows to pearl pedestal 15.Ball 10 is spherical, is maintained in the pearl pedestal 15 of ballpoint tip main body 11 and rotatable.That is, rear end side is by bearing surface 45, and side is by cylindrical wall 41, front after inserting at ball 10, keeps ball 10 by front end crushed element 43, front end crushed element 43 is after ball 10 inserts, the front end crushed element to the inside that is closed up and make ballpoint tip main body 11.
Above-mentioned pearl pedestal 15 has as the sidewall cylindrical wall 41, the bearing surface 45 that is positioned at cylindrical wall 41 rear end side and the joint face 71 that form the cylinder interior shape.Joint face 71 is the faces that connect cylindrical wall 41 and bearing surface 45.Bearing surface 45 is to form by the pressure pearl that ball 10 is pressed from front thruster to the back-end.The shape of joint face 71 is parts of cone surface, is the mortar shape.
