Title (EN) REFILL FOR WRITING TOOL AND WRITING TOOL USING SAME
(FR) RECHARGE POUR OUTIL D'ÉCRITURE ET OUTIL D'ÉCRITURE UTILISANT CELLE-CI
(JA) 筆記具用リフィールおよびこれを用いた筆記具
Abstract:
(EN) The purpose of the present invention is to secure a necessary storage amount of ink without increasing the outer diameter dimension of an ink containing tube, and enable a comfortable feeling of writing to be continued without causing any uncomfortable feeling of writing touch. Provided is a refill for a writing tool, comprising: an ink containing tube formed from resin material to have a linear and cylindrical shape; and a writing tip mounted to the end portion of the ink containing tube, wherein when the outer diameter of the ink containing tube is represented by D [mm] and the thickness of the ink containing tube is represented by t [mm], a relationship between the outer diameter D and the thickness t is selected such that the value of [D4 - (D - 2t)4] is 45 or more.
(FR) Le but de la présente invention est de garantir une quantité de stockage d'encre nécessaire sans augmenter le diamètre externe d'un tube contenant de l'encre, et de permettre une sensation agréable d'écriture sans provoquer de sensation désagréable de toucher d'écriture. L'invention concerne une recharge pour un outil d'écriture, comprenant : un tube contenant de l'encre formé à partir d'un matériau de résine pour avoir une forme linéaire et cylindrique ; et une pointe d'écriture montée sur la partie d'extrémité du tube contenant de l'encre, dans laquelle, lorsque le diamètre externe du tube contenant de l'encre est représenté par D [mm] et l'épaisseur du tube contenant de l'encre est représentée par t [mm], une relation entre le diamètre externe D et l'épaisseur t est sélectionnée de telle sorte que la valeur de [D4 - (D - 2t)4] est égale ou supérieure à 45.
(JA) インク収容管の外径寸法を拡張することなく、必要なインクの貯留量を確保すると共に、インク収容管の外径寸法を拡張することなく、必要なインクの貯留量を確保すると共に、筆記の感触に違和感が生ずることなく、快適な筆記が継続できるようにする。樹脂素材により直線状にして円筒状に形成されたインク収容管と、インク収容管の端部に取り付けられた筆記チップとを備えた筆記具用リフィールであって、インク収容管の外径をD〔mm〕とし、インク収容管の肉厚をt〔mm〕とした時、〔D-(D-2t)〕の値が、45以上となるように外径Dと肉厚をtの関係が選定される。
