  • Patent number: 9414722
    Abstract: A ballast system is provided for stabilizing a six-panel rectangular paperboard box containing a stack of inter-folded tissue sheets and having a opening in a top panel thereof for removal of individual tissue sheets. The ballast system includes at least two laminar backing plates fabricated from ferromagnetic material, the backing plates being positionable on an interior surface of said paperboard box, and at least two permanent magnets positionable on an exterior surface of said paperboard box, each permanent magnet securing itself and one backing plate to the paperboard box, with one of the six panels sandwiched therebetween. The box, the backing plates and the permanent magnets have a combined mass sufficient to prevent the box from being lifted from a surface on which it is resting when a tissue is pulled from the box through the opening as the number of folded tissues in the box approaches zero.
