【産業上の利用分野】[Industrial applications]

本考案は、筆記具、化粧用筆記具などの筆記具のキャップ内面に取り付けられ 、軸筒へのキャップ嵌合時、軸筒への位置を安定させるために軸筒と当接する内 方への膨出部を有する筆記具のキャップにおけるバネに関する。 The present invention is attached to the inner surface of a cap of a writing instrument such as a writing instrument and a cosmetic writing instrument, and when the cap is fitted to the axial tube, the inward bulging portion that abuts the axial tube to stabilize the position of the axial tube. The present invention relates to a spring in a cap of a writing instrument.

【従来の技術】[Prior art]

従来、筆記具において、キャップに軸筒をブレがないように固定し、キャップ と軸筒との嵌合時、しっとり感を出すため、内方への膨出部を有するバネをキャ ップ内面に固着せしめるものであるが、キャップの開け閉め回数が増えるに従い バネと軸筒表面との摩擦により、軸筒表面に傷が生じるという問題がある。 この問題に対する解決策としては、アルマイト処理、クロムめっき等により、 軸筒表面を硬質にするように表面処理を行ない、耐摩耗性、耐久性を向上させ、 摩擦による傷の発生を防ぐ方法、軸筒とバネとの当接部分をカ−トリッジ先端に 設け、傷が生じても交換可能とする方法、少なくとも軸筒との当接部分をフッ素 系樹脂によりコーティングする方法などが提案されている。 Conventionally, in writing instruments, the shaft cylinder is fixed to the cap so that there is no blurring, and a spring with an inward bulge is placed on the inner surface of the cap to give a moist feeling when the cap and the shaft cylinder are fitted. Although it is fixed, there is a problem in that as the number of times of opening and closing the cap increases, the friction between the spring and the surface of the barrel causes damage to the surface of the barrel. The solution to this problem is to use alumite treatment, chrome plating, etc. to make the surface of the shaft cylinder hard to improve the wear resistance and durability, and to prevent scratches due to friction. A method has been proposed in which a contact portion between the cylinder and the spring is provided at the tip of the cartridge so that it can be replaced even if a scratch occurs, or a method in which at least the contact portion with the shaft cylinder is coated with a fluororesin.

【考案が解決しようとする課題】[Problems to be solved by the device]

表面処理により、軸筒表面を硬質にする方法は、金めっき、塗装等といった他 の表面処理が使えず、近年強く要望されている表面処理による外観意匠多様化に 対応しきれないものであり、又、カ−トリッジにすることにより傷が生じても交 換可能としたタイプのものは、使い捨てのため、コストの面で制約を受け、上記 要望に対応する外観意匠が得られにくく、得られる外観意匠にも限りがあり、問 題の多いものであり、更に、少なくとも軸筒との当接部分をフッ素系樹脂により コーティングするものは、軸筒に対する傷の発生は少なくなるものの、滑り易い ため、キャップの脱着時にしっくりした感触が得られないという問題があった。 The method of hardening the surface of the barrel by surface treatment cannot use other surface treatments such as gold plating and painting, and cannot fully support the diversification of appearance design by surface treatment which has been strongly demanded in recent years. In addition, the type that can be replaced even if scratches occur due to the cartridge is disposable, so it is limited in cost, and it is difficult to obtain an external appearance design that meets the above requirements, and it can be obtained. The appearance design is limited, and there are many problems.Furthermore, in the case where at least the contact part with the barrel is coated with a fluororesin, the occurrence of scratches on the barrel is less, but it is slippery. However, there was a problem that a comfortable feel was not obtained when the cap was attached and detached.
