PROBLEM TO BE SOLVED: To provide a foamed plastic container having satin-like appearance which is a foamed plastic container that is formed of a thermoplastic resin and has a container wall having a non-laminated structure, and has a foamed region where foamed cells are distributed inside of the container wall existing on a part of a body portion.SOLUTION: In a foamed container which is a foamed plastic container that is formed of a thermoplastic resin and has a container wall having a non-laminated structure, and has a foamed region where foamed cells are distributed inside of the container wall existing on a part of a body portion, a surface of the body portion has a smooth surface having surface roughness Ra of 5 μm or less, in an outer surface of the body portion in the foamed region, a large number of dark portions D having low light reflection ratios are distributed between bright portions L having high light reflection ratios, which exhibits a satin-like pattern.SELECTED DRAWING: Figure 5 【課題】熱可塑性樹脂からなり且つ非ラミネート構造の器壁を有していると共に、該器壁内部に発泡セルが分布している発泡領域が少なくとも胴部の一部に存在している発泡プラスチック容器において、梨地様外観を有する発泡プラスチック容器を提供する。【解決手段】熱可塑性樹脂からなり且つ非ラミネート構造の器壁を有していると共に、該器壁内部に発泡セルが分布している発泡領域が少なくとも胴部の一部に存在している発泡プラスチック容器において、前記胴部の表面は、表面粗さＲａが５μｍ以下の平滑面となっていると共に、前記発泡領域での胴部の外面は、光線反射率が低い暗部Ｄが該光線反射率の高い明部Ｌの間に多数分布しており、これにより、梨地様模様を呈していることを特徴とする。【選択図】図５
