A dual compartment box features slides which move sideways to uncover openings for dispensing two different types of solid pourable products. It is made from a single cardboard blank having a plurality of panels extending lengthwise and connected together. The box is formed by folding the panels into a pair of adjacent compartments, with a top panel folding over to encapsulate the slides. The slides are detachable from the front panel and moveable sideways to uncover openings which form dispensing paths for the two types of solid pourable products. The slides preferably remain attached to side panels of the box, and then can be moved back to close off the dispensing paths if all the product is not immediately used. A bottom portion of the box is configured with conventional flaps and the box can be filled from the bottom or the top.
