Description of the Related Art Problems to be solved by the prior art and the present invention: Conventionally, when writing is performed with an applicator such as a correction liquid pen using a ball as a writing medium and a volatile solvent as a coating liquid, and drying of ink around the ball during writing. At the tip of a pen used for ballpoint pens that use medium- and low-viscosity inks and inks that have thixotropic properties that affect performance, place a coil spring inside and press the ball against the inner wall of the caulking part at the tip of the holder when not in use. There are many pen tip structures using a ball as a writing medium, which uses a holder having a valve mechanism and a ball seat that receives the writing pressure applied to the ball at the time of use and smoothens the rotation of the ball.

脱落してしまう問題があった。In many of these pen tip structures, a mover is provided between the ball and the coil spring, and the ball is pressed against the inner wall of the caulking part of the holder through the mover. In this type of applicator, the mass of the mover is large with respect to the balls, so the applicator may be accidentally dropped on the floor, or the application liquid may be agitated violently during use. When the force of the mover pressing the ball becomes extremely strong, the ball broke the caulked portion at the tip of the holder and fell off.

る。In order to solve this kind of problem, the mass of the mover and the coil spring used as a means for pressing the ball against the inner wall of the caulking portion at the tip of the holder is made small, that is, the mass can be stored in the holder in a small space. By doing so, it is possible to reduce the impact force applied to the caulked portion at the tip of the holder via the ball when it is dropped on the floor or when the applicator is shaken violently for stirring the coating liquid, for example, in Japanese Utility Model Laid-Open No. 5-76568. The invention and the invention of No. 5-76569, in which a coil spring having a small mass is directly brought into contact with the ball surface without using a mover, have been made. For example, as shown in the invention of Japanese Utility Model Laid-Open No. 6-11873, it is necessary to unitize the mover and the coil spring in the holder. A new problem has arisen and the Hitoshi Jiru.

ール脱落の危惧を払拭したことである。SUMMARY OF THE INVENTION In view of the above situation, the present invention has a minimum number of parts and a required function, that is, the coating liquid or the ink is prevented from drying around the ball. The present invention attempts to develop a pen tip structure that is effective and can be executed without causing other problems, by using a valve mechanism formed by an inner wall. One of the indispensable points of the attempt was to first make the coil springs symmetrical to the left and right and make the assembly direction, which is an important requirement when assembling the applicator or the ballpoint pen, unrelated. One of the two points is that the coil spring mounted on the spring receiving part of the holder holding member is structured so that it is stably held in the spring receiving part, so even if it is accidentally dropped on the floor or shaken strongly, It is possible to prevent a strong force from being applied to the caulked part of the tip of the holder and to eliminate the fear of the ball falling off.

Formed by providing an intermediate coil part with a diameter,
Alternatively, a straight line may be formed by bending both ends of the intermediate coil portion toward the axis and further bending in the axis direction at the center of the coil diameter and extending outward in the axial direction from the end winding portion to the left and right respectively. It is formed by providing a rod-shaped portion, both of which are left-right symmetrical shapes, and the directionality at the time of assembly is not questioned.

連の組立機内で容易に得られることになる。In the pen tip portion constituted by the above means, one end side of the coil spring formed in the left-right symmetrical shape is fitted and held in the spring receiving portion of the holder holding member and the other end side is held. Since it holds the ball in a stable and upright state, when assembling the holder that holds the ball by crimping it into the holder holding member, it is possible to load the coil spring into the holder without fail and after the assembly, the ball is coiled. Push it up with one end of the holder and put it on the inside wall of the holder by ca.
A valve mechanism which is biased by an elastic force of 00 gr can be easily obtained in a series of assembling machines for assembling an applicator such as a correction fluid and a ballpoint pen using medium / low viscosity ink.

Since it is fitted and held in the spring receiving part, it is prevented that excessive force is applied to the ball even if it accidentally drops on the floor or shakes the container vigorously for stirring the correction fluid. There is no problem of breaking the caulked part and dropping it. In addition, since the coil springs are formed symmetrically to the left and right and the directionality is not required during assembly, parts can be smoothly fed from the parts feeder in the automatic assembly machine, and the coil springs can be fitted to the holder holding member first. After attaching, the holder that crimps and holds the ball can be sequentially attached to the holder holding member in the form of covering the coil spring with the coil spring.Therefore, it is troublesome to make a separate machine assembly with the coil spring or mover in the holder. It is possible to efficiently assemble the product.

By setting the left and right symmetrical coil springs, the holder holding member, and the ink storage container as appropriate, product assembly with a normal automatic assembly machine can be easily realized, and the ball is always crimped at the tip of the holder. Combined with the function of the pressing valve mechanism on the inner wall of the part, excellent writing performance without ink drying around the ball and performance without worrying that ink will be ejected even when the pen tip is facing downward Therefore, the present invention can be used, for example, as a refill for a knock-type ballpoint pen in which the pen tip portion is carried downward. Moreover a nib portion structure utilized in range of applications, serve to provide a simplistic.

A ball for locating a coil spring inside and pressing the ball against the inner wall of the caulking part at the tip of the holder when not in use to form a valve mechanism for receiving writing pressure applied to the ball and smoothing the ball in use. In a pen tip part using a coating medium such as a correction fluid having a seat and a ball used for a medium / low viscosity ink ball-point pen, the coil spring (6) is made of non-rust steel or a wire material subjected to anti-rust treatment,
Intermediate coil part (6 with mounting load of 10 to 100 gr)
b) is provided, is bent toward the axial center at both end winding portions (6c) of the intermediate coil portion, and is further bent in the axial center direction at the center of the coil diameter so that the axial center is outward to the left and right of the end winding portion. Formed by providing a linear rod-shaped portion (6a) extending in the direction,
The ball (3) is held in the holder (2) by contacting the end surface of the rod-shaped portion of the coil spring with the ball surface and attaching and holding a part of the intermediate coil portion to the spring receiving portion (5a) of the holder holding member (5). A pen tip portion ( 7 ) structure using a ball as a writing medium characterized by being urged in the tip direction.
