Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a synthetic resin bottle with excellent design in which color change such as yellow discoloration is masked so as to be inconspicuous even when used for a long period.SOLUTION: The synthetic resin bottle is obtained by molding a composition containing 4-7 wt.% of master batch composed of 87-92 wt.% of polyethylene terephthalate, 3-6 wt.% of nylon and a bluing agent, and has a thickness of 0.2-0.5 mm, and the yellow discoloration by a reaction of an acetaldehyde and a nylon can be masked so as to be inconspicuous by bluing. 【課題】長期間使用しても黄変等の変色が目立たないようマスクする意匠性に優れた合成樹脂製ボトルに関する。【解決手段】この発明の合成樹脂製ボトルは、ポリエチレンテレフタレート８７〜９２重量％、ナイロン３〜６重量％、及びブルーイング剤を含んだマスターバッチ４〜７重量％を含む組成物を成形することで得られる肉厚が０．２ｍｍ〜０．５ｍｍの容器であることを特徴とし、アセトアルデヒドとナイロンとの反応による黄変をブルーイングで目立たないようにマスクすることができる。【選択図】図１
