Description
実施例1の構成を、図7を用いて説明する。図7(a)はインクカートリッジの筐体の上面図及び断面図、図7(b)はC-C´断面におけるフランジの拡大図、図7(c)は外層フランジをフランジの高さ方向(延伸方向、図7(b)の上から下に向かう方向)から見た図である。
実施例2の構成を、図8を用いて説明する。図8(a)はインクカートリッジの筐体の上面図及び断面図、図8(b)はD-D´断面におけるフランジの拡大図、図8(c)は外層フランジをフランジの高さ方向(延伸方向)から見た図である。
実施例3の構成を、図9を用いて説明する。図9(a)はインクカートリッジの筐体の上面図及び断面図、図9(b)はE-E´断面における図9(a)のフランジの拡大図、図9(c)は外層フランジをフランジの高さ方向(延伸方向)から見た図である。
実施例4の構成を、図10を用いて説明する。図10(a)はインクカートリッジの筐体の上面図及び断面図、図10(b)はF-F´断面におけるフランジの拡大図、図10(c)は外層フランジをフランジの高さ方向(延伸方向)から見た図である。
実施例5の構成を、図11を用いて説明する。図11(a)はインクカートリッジの筐体の上面図及び断面図、図11(b)はフランジをフランジの高さ方向(延伸方向)から見た図である。図11(b)に示すように、実施例5では、実施例1の窪みではなく、筐体(フランジ)を高さ方向から見た場合の、外層フランジと内層フランジの接触領域において、外層フランジに窪み37を設けた。この窪み37には、内層フランジの突起を、窪み37と同じ大きさで嵌合させた。即ち、筐体を高さ方向から見たときに、窪み及び突起の凹凸が見えるようになっている。窪み37及び突起は、円周状ではなく、図11(b)に示すような形状で形成した。これ以外は実施例1と同様にして、インクカートリッジの筐体の成形を行った。
比較例の構成を、図12を用いて説明する。図12(a)はインクカートリッジの筐体の上面図及び断面図、図12(b)はG-G´断面におけるフランジの拡大図、図12(c)は外層フランジをフランジの高さ方向(延伸方向)から見た図である。
