  • Patent number: 7647893
    Abstract: A corrugated cardboard assembly having a plurality of adjacent sheets of corrugated cardboard arranged in a layered fashion to form a corrugated block. The adjacent sheets are not attached to one another using any adhesive. Instead, the block formed by the layered, adjacent sheets of corrugated cardboard is enveloped by a wrap-around carton that maintains the adjacent positioning of the sheets. The sheets, individually and collectively, include at least one opposing straight, narrow cut, opening, aperture, or “slit,” that is defined within them. The wrap-around carton includes interlocking portions of the carton in combination with a longitudinally extending slot that is formed by the slits that are defined within each of the adjacent sheets of corrugated cardboard. In this fashion, the block formed by the adjacent sheets is maintained without the use of extra glue or adhesive to maintain the structural integrity of the block of adjacent sheets.
