<p>An automatically-operating bottom structure for use in a collapsible container includes a band (80, 84) pivotally connected to a first pair of panels (16, 20), a first pair of bottom flaps (120, 122 and 160, 162) connected to a second pair of panels (18, 22), a second pair of bottom flaps (124, 126) connected to a third pair of panels (17, 19), a third pair of bottom flaps (164, 166) connected to a fourth pair of panels (21, 23), a first pair of web panels (128, 130) and a second pair of web panels (168, 170). 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.</p> |
