An automatically-operating bottom structure for use in a collapsible container includes a band (1080, 1084; 2080, 2084) pivotally connected to a first pair of panels (1016, 1020; 2016, 2020), a first pair of bottom flaps (1120, 1122 and 1160, 1162; 2120, 2122 and 2160, 2162) connected to a second pair of panels (1018, 1022; 2018, 2022), a second pair of bottom flaps (1124, 1126; 2124, 2126) connected to a third pair of panels (1017, 1019; 2017, 2019), a third pair of bottom flaps (1164, 1166; 2164, 2166) connected to a fourth pair of panels (1021, 1023; 2021, 2023), a first pair of web panels (1128, 1130; 2128, 2130) and a second pair of web panels (1168, 1170; 2168, 2170). The band and bottom flaps are folded within the container when the container is in a folded-flat condition, but automatically form an operative bottom structure when the folded-flat container is moved to a fully-expanded condition.
