Container with magnet for holding it in position

A portable container for use by construction workers to carry food and miscellany comprising a hollow body having side and bottom walls and a top opening, the walls of said body being insulated to resist the transmission of heat therethrough, a removable tray adapted to be stored in said body, means provided on the interior of the sidewalls of said body for supporting said tray in an upper region of said body, said tray having a plurality of compartments therein adapted to snugly receive the items of food or miscellany, a lid structure hingedly mounted on said body for closing and opening the opening of said body, said lid structure being insulated to resist the transmission of heat therethrough, means for locking said lid structure in closed position on said body, means providing a handle for carrying the container, and magnet means carried by the bottom wall of said body for holding said container in position on a magnetically attractable structure, said magnet means having a lower face directed toward said attractable structure, said magnet means including movable means for reducing the attractive force thereof to facilitate removal of the container from said attractable structure, said movable means including at least one shunt shield for shunting the magnetic field of said magnet means when positioned between the lower face of said magnet means and said attractable structure, said at least one shunt shield being movably secured to the bottom wall of said body between a first position overlying the lower face of said magnet means to reduce the attractive force between said magnet means and said attractable structure and a second position withdrawn from the lower face of said magnet means for exposing the lower face thereof and allowing said magnet means to exert its maximum attractive force upon said attractive structure.
