が発生しやすい等の問題がある。2. Description of the Related Art Conventionally, a writing instrument equipped with a volatile ink such as a marker or a felt-tip pen is provided with a cap for sealing a pen tip. Therefore, there are problems such as the trouble of attaching and detaching the cap and the loss of the cap. Many capless writing instruments are known to solve such problems, but those without a sealing mechanism are difficult to withstand long-term storage, and even if possible, ink that is hard to volatilize. By installing, it is easy for problems such as the drawn lines to be difficult to dry. Furthermore, there are few capless type products that have reliably overcome the sealing properties. Further, although there is a case of sealing with an opening / closing lid as in the present application, the structure is complicated and cannot be provided at low cost. Also, there is a type that uses a connecting part such as a string to open and close the lid part, but there is a problem that the opening and closing mechanism is not stable and a defect due to drop impact or manufacturing variation easily occurs.

したもの、等々でも本発明と同様の効果が得られる。It should be noted that the O-ring 5 is in close contact with the inner peripheral wall of the slider 3 and is in contact with the inner peripheral wall in a slidable range. The O-ring 5 is made of a material such as rubber, silicon or elastic resin in order to reduce frictional force. Alternatively, coating with oil or the like is devised.
Further, a sealing material having a semi-fluidity may be applied instead of the O-ring, and the O-ring may be omitted if the refill cylinder 7 is formed of soft polyethylene having elasticity. Further, by fixing a tubular rubber component inside the slider 3, coating the inner surface, and making the slider 3 a rubber component, the same effect as the O-ring can be obtained. By the way, a synthetic resin material or a metal material capable of preventing evaporation of ink is selected for the lid body 2, slider 3, writing refill cylinder 7, and tail plug 8, respectively. In particular, a solvent such as xylene is used. In the used marker (so-called oil-based marker), the ink evaporation component permeates through a material such as rubber or PP or PE. Therefore, a material having solvent permeation preventive property such as PBT, metal or glass is selected. Between the lid 2 and the slider 3 as described above, it is free to use a material such as elastic PBT for the O-ring without using a rubber part as a combination of a taper and a circumferential sealing surface. However, if the shaft cylinder 1 is a member separate from the refill cylinder 7, the exterior part is not limited thereto, but the refill cylinder 7 may be omitted and the shaft cylinder 1 may be substituted.
In that case, the shaft cylinder 1 must also be a similar ink evaporation suppressing member. Further, if the lid portion of the lid body 2 and the leg portion 2-a are formed separately, only the lid portion may be made of a material capable of preventing evaporation. Furthermore, a minimum of two or more combinations of pins and long windows are required. However, even if the combination of three or more links is required due to the requirements of appearance and operation, the combination of pins and long windows will still be suitable. If the installation member is reversed (the guide groove portion 14 is provided on the lid body 2 and the pin B is provided on the slider 3), the pin may be a separate member, and so on. The same effect as the invention can be obtained.

Is moved downward and can be stored without protruding from the outer periphery of the shaft cylinder 1, and there is an advantage that the lid 2 does not get in the way during writing, which is a difference from the first embodiment. Further, for the purpose of improving the sealing property and slidability, oil, grease, soap, coating or the like may be applied to each sealing portion or sealing member, or the material may be directly kneaded and molded.

確実なシールがなされる。The capless writing instrument of the present invention is constructed as described above, and when not in use, the lid 2 seals the opening of the slider 3 as shown in FIGS. The portion is tightly fitted between the inner wall of the slider 3, the lid 2, the O-ring 5 and the writing body to prevent evaporation of ink and drying of the pen tip 9. Further, as shown in FIGS. 3 and 11, when the button 4 is moved backward, the slider 3 is moved backward, the connecting portion is interlocked, the lid body 2 is rotated approximately 90 °, the opening is opened, and the slider is further retracted. Thus, the pen tip 9 of the writing body is locked in a state of protruding from the opening, and the writing state is set. At that time, until the lid 2 is expanded by retracting the slider 3, the pins of the connecting portions of the plurality of combinations are respectively moved along the long window, so that the lid 2 acts to turn and automatically. The cap is removed. Further, the slider 3 is moved forward and the writing body is automatically accommodated and the reliable sealing is performed only by releasing the engagement of the button 4 with the shaft cylinder 1.
