Description

本発明は、筆記具用キャップに関し、さらに詳しくは、色付きの樹脂材からなるキャップ本体の開口部に、前記キャップ本体の色と異なる円環部材を挿着して成す構造の筆記具用キャップに関する。 The present invention relates to a writing instrument cap, and more particularly to a writing instrument cap having a structure in which an annular member different from the color of the cap body is inserted into an opening of the cap body made of a colored resin material.

射出成形による樹脂材で形成された筆記具用キャップは一般的であり、そのキャップ本体の開口部に金輪等の円環部材を付設して装飾性の向上や当該開口部の強度向上を図ったものもよく知られている。この円環部材は、キャップ本体から筆記具を抜き差しをする際に脱落し難くするために、螺子止めや圧入等でキャップ本体に対して固定してある。さらにキャップ本体と円環部材とを強固に固着させる方法として、実開昭６３−４７１８６号公報に開示されているように接着剤を用いる固着方法が、キャップ本体と円環部材との接合に採用される場合もある。
「実開昭６３−４７１８６号公報」 Caps for writing instruments formed of resin material by injection molding are common, and an annular member such as a metal ring is attached to the opening of the cap body to improve decoration and strength of the opening Is well known. This annular member is fixed to the cap main body by screwing or press-fitting or the like in order to make it difficult to drop off when the writing instrument is inserted and removed from the cap main body. Furthermore, as a method for firmly fixing the cap body and the annular member, a fixing method using an adhesive as disclosed in Japanese Utility Model Publication No. 63-47186 is employed for joining the cap body and the annular member. Sometimes it is done.
“Japanese Utility Model Publication No. 63-47186”

ところで、キャップ本体の開口部に金輪等の円環部材を付設する場合には、筆記具の抜き差しに支障がないように、円環部材の内面とキャップ本体の内面とを一致させた方がよく、キャップ本体の内面を薄肉に形成して、そこに円環部材を挿着することが多い。しかしこのような方法では、特にキャップ本体が白やアイボリー等の淡色の樹脂材からなる際に、キャップ本体の薄肉に形成した箇所が透けてしまい、その内側に位置する円環部材の挿着部が、前記キャップ本体の色と異なる時に、その円環部材の挿着部が影のように透けてしまうという問題があった。また、キャップ本体に対する円環部材の接着強度を確かなものとするために、円環部材の挿着部の円周上に接着剤を溜める溝部を形成する場合もあるが、この構造では、キャップ本体の薄肉の箇所から溝部による複数の筋が透けて、さらに見栄えが悪くなるという問題があった。 By the way, when attaching an annular member such as a metal ring to the opening of the cap body, it is better to match the inner surface of the annular member and the inner surface of the cap body so as not to interfere with the insertion and removal of the writing instrument, In many cases, the inner surface of the cap body is formed thin and an annular member is inserted therein. However, in such a method, especially when the cap body is made of a light-colored resin material such as white or ivory, the portion formed in the thin wall of the cap body is transparent, and the insertion portion of the annular member located inside the cap body However, when the cap body is different from the color of the cap body, there is a problem that the insertion portion of the annular member is transparent like a shadow. In addition, in order to ensure the adhesive strength of the annular member to the cap body, a groove portion for storing an adhesive may be formed on the circumference of the insertion portion of the annular member. There was a problem that a plurality of streaks due to the groove portion was seen through the thin-walled portion of the main body, and the appearance further deteriorated.

本発明はこうした問題を鑑みて、挿着受部の内側が透ける程に薄肉に形成したキャップ本体であっても、挿着した円環部材の挿着部が影のように透けてしまうことのない筆記具用キャップとすることを目的とする。 In view of these problems, the present invention is such that even if the cap body is formed so thin that the inside of the insertion receiving portion is transparent, the insertion portion of the inserted annular member is transparent like a shadow. The aim is to have no writing instrument cap.

本発明は、
「１．色付きの樹脂材からなるキャップ本体の開口部に、前記キャップ本体の色と異なる円環部材を挿着して成す筆記具用キャップにおいて、前記キャップ本体における前記円環部材が挿着される箇所である挿着受部を、該キャップ本体に該円環部材を挿着した状態で当該キャップ本体の内面と当該円環部材の内面とが一致するよう薄肉に形成し、且つ前記キャップ本体に挿着する円環部材の挿着部と該キャップ本体の挿着受部との間に当該キャップ本体の色と同色である接着剤を介在させて、前記キャップ本体と前記円環部材とを固着したことを特徴とする筆記具用キャップ。
２．前記円環部材の挿着部の円周上に、接着剤を溜める溝部を設けてあることを特徴とする１項に記載の筆記具用キャップ。」
