Abstract: At least two trays are positioned over each other which are lockable by a cover. One of the trays is a drawer which is lockable in an inserted position with the cover. The paint box can have an upper and a lower tray and the upper tray can comprise a rectangular housing with a foldable cover. The rectangular housing has double side walls extending downwardly and forming a guide for the lower tray which is the drawer. The undersurface of the drawer can form the supporting surface for the housing while the upper tray housing rests on the drawer. The double side walls of the rectangular housing end with a small space above the bottom plane of the drawer and the inserted edge of the drawer can be lowered an amount corresponding to that small space. The pulled out end of the drawer can have a strap which projects upwardly over the upper tray and engages under the edge of the foldable cover.
