- the present invention exhibits the following excellent effects.
- a refillable pen with a replaceable ink tank is used as a collector ball pen, so a ball pen with excellent cost performance can be obtained by adding an inexpensive ink tank that is slender and has a good appearance.
- the mechanism that suppresses the volatilization of the ink prevents the ink from solidifying even if the cap is forgotten for several days, or the cap is used when the ink is a non-dry type formulation such as a combination of a hygroscopic material. This eliminates the need for hermetic sealing with the convex portion of the cap, which eliminates the need for a pumping phenomenon and eliminates the need for a complicated pumping-resistant mechanism, and also makes full use of the collector storage mechanism in terms of performance.
- the ink tank As the ratio of the collector and the ink tank increases, the larger the ink tank is, If the air expansion inside the ink tank increases and the volume expands beyond the volume adjustment capability of the collector, the ink will blow out from the air holes.However, in the present invention, there is no problem in terms of cost performance even if the capacity of the ink tank is reduced. Can reduce the tank capacity of about 3 cc for normal disposable use to about 1 cc, and replace the ink tank about 5 times until the tip inside wears out and becomes unusable. It is about three times safer and will be an inexpensive ballpoint pen at about half the price by the same life. It is more effective when the pen tip is made of a material with high hardness or an ink with high wear resistance.
- the effect of the present invention can be made effective by making the member that comes into contact with the outside air on the outer peripheral surface of the pen body effective in moisture prevention.Select only a material that has a water absorption of 0.2% or less and does not hydrolyze. This has the effect of eliminating the problem that the ink is volatilized and solidified, and in particular, the problem of cracking in the case of an ink having strong force. In particular, when a small amount of a hygroscopic material is blended or an ink that is slightly volatilized and hardens more hardly than in the past is used, it has an effective action that can be used as a capless writing instrument. Industrial applicability
- a ballpoint pen which is slender, has a good appearance, and is excellent in cost performance. Prevents the ink from solidifying and deteriorating even if the cap is forgotten, eliminates the need for a cap, and eliminates the need for hermetic sealing with the convex part of the cap, so there is no pumping phenomenon and complicated pumping resistance No mechanism is required.
