Abstract: A collapsible storage container made of a pair of foldable end panels, each comprising two panel pieces hingedly connected together. The end panels are connected with hinges to two side panels. At the bottom of each side panel a bottom panel is attached with hinges. This means that the collapsible storage container can be put in a usable “box” position by straightening the foldable end panels and folding down the bottom panels, and also can be put in a flat storage position by folding up the bottom panels and folding the foldable end panels until the outside surfaces of panel pieces touch each other.
