  • Patent number: 5226571
    Abstract: A box dispenser for dispensing rolled-materials is fabricated of single wall corrugated board having a corrugated medium comprising E-flute glued between two facings. The dispenser is provided with a cutting edge. The cutting edge is formed by die-cutting an appropriate edge of the box adjacent to the dispensing opening to form serrations. The cutting edge is reinforced and strengthened by filling the interstitial voids between the two facings and the fluting at the cutting edge with a fast setting glue which adheres to the fluting and facings to provide a rigid, reinforced cutting edge which can resist being crushed or dulled by constant dispensing of the rolled material.
