The flap has a cutting board surface and at least one shaft for pivotally coupling the flap (5) to the side walls so that the flap (5) is swivelable from a closed position where the flap closes the front opening of the breadbox (5) to an open position where the breadbox is open and the flap (5) is positioned substantially in a horizontal plane, such that the flap (5) has the cutting board surface exposed upwardly so as to be usable as the cutting board. The breadbox has a receptacle for crumbs which is disengageably attached to the front edge of the bottom of the breadbox.
