A collapsible container includes a base and a plurality of walls moveable between and upright position and a collapsed position. Adjacent walls are connected via a latch protruding laterally from a first wall. The latch includes a first ramped surface that engages the adjacent second wall to deflect the latch in the direction generally parallel to the plane of the first wall as the second wall is moved to the upright position. The latch also includes a second ramped surface that engages the second wall when the second wall is in the upright position. The second wall can be collapsed by manually actuating the latch in a normal manner for latched containers. Additionally, the second wall can be collapsed by knocking down the second wall thereby causing the second wall to engage the second ramped surface on the latch causing deflection of the latch and release of the second wall.
