A chuck box, also called a patrol box or grub box, is a device used by campers for storing the many items associated with a camp kitchen. When packed up, it looks like a large box and traditionally contains kitchen items such as cooking pots, pans, plates, utensils, and cleaning items. The box will unpack (usually with a fold down front and sides) to reveal its contents in specifically designed compartments, shelves, drawers and racks.A patrol box is sometimes referred to jokingly as the "ark of the condiments."
