Resin container

The present invention provides a resin container (11) provided with: an upper surface part (21); a side surface part (22) connected to the upper surface part (21); and a bottom surface part (23) disposed on the side opposite the upper surface part (21) and connected to the side surface part (22). A round corner surface part (25) is formed on the side surface part (22), and first foldable deformation inducing parts (31) are formed on the round corner surface part (25). The first foldable deformation inducing parts (31) are slanted with respect to the central axis (A) when viewing the resin container (11) from the side surface part (22) so that the central axis (A) and the round corner surface part (25) of the container (11) overlap. 本发明提供一种树脂制容器(11)，该树脂制容器(11)包括上面部(21)、与上面部(21)相连的侧面部(22)、以及配置于与上面部(21)相反的一侧且与侧面部(22)相连的底面部(23)，在侧面部(22)形成有圆角面部(25)，在圆角面部(25)上形成有第一折叠变形引导部(31)，在以容器(11)的中心轴线(A)和圆角面部(25)重叠的方式从侧面部(22)侧观察容器(11)时，第一折叠变形引导部(31)相对于中心轴线(A)倾斜。
