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.

The details of the invention having been disclosed in accordance with the foregoing, I claim: 1. A corrugated cardboard assembly that comprises a plurality of sheets of corrugated cardboard, a wrap-around carton, and means for interlocking a portion of the carton with the plurality of cardboard sheets, said sheets are arranged in a layered fashion to substantially fill the carton and the sheets are enveloped by the carton. 2. The assembly of claim 1 wherein each sheet of the plurality of cardboard sheets is substantially similarly configured and wherein each sheet comprises a sheet edge disposed between a pair of sheet legs. 3. The assembly of claim 2 wherein said interlocking means comprises a slit that is defined within each of the sheet legs of each sheet of the plurality of cardboard sheets, each of said slits extending inwardly of the respective sheet leg from the sheet edge and further extending upwardly relative to the horizontal. 4. The assembly of claim 3 wherein said interlocking means further comprises two opposing slots that are formed by the adjacent slits defined in each of the legs of the layered plurality of cardboard sheets. 5. The assembly of claim 4 wherein said interlocking means further comprises two portions of the wrap-around carton, each portion being receivable within one of the two opposing slots formed by adjacent slits defined in each of the legs of the layered plurality of cardboard sheets and each portion being biased within the respective slot whereby the respective carton portion is not easily withdrawn from the slot into which it has been received. 6. A corrugated cardboard assembly that comprises a plurality of die-cut corrugated cardboard sheets, each sheet being substantially like-configured and comprising a sheet edge disposed between a pair of sheet legs and a slit defined in each sheet leg, each slit extending inwardly of the respective sheet leg from the sheet edge and being angled, and the plurality of sheets being arranged in a side-by-side layered fashion to form a block of corrugated cardboard material, and a die-cut corrugated wrap-around carton member, said carton member being formed with at least one lip, said lip being interlockingly engagable within a slot that is formed by the adjacent slits that are defined within the legs of the plurality of layered cardboard sheets, wherein the structural integrity of the assembly is maintained when the wrap-around carton member envelopes the plurality of sheets that substantially fill the carton and the at least one lip of the carton member is engaged with the slot that is formed by the plurality of adjacent slits. 7. The assembly of claim 6 wherein the wrap-around carton member comprises a bottom floor, a front face portion, a rear face portion, a first side face and a second side face, the first side face further comprising a foldable extension portion and a leading lip, and the second side face further comprising a foldable extension portion and a leading lip. 8. The assembly of claim 7 wherein the leading lips of the first and second side faces are each receivable within a slot that is formed by adjacent slits defined within the plurality of sheets. 9. The assembly of claim 8 wherein each slit defined within each sheet is angled upwardly relative to the horizontal to capture the leading lips of the first and second side faces of the carton member. 10. A method of making a corrugated cardboard assembly that comprises the steps of providing a plurality of sheets of corrugated cardboard, each sheet being substantially like-configured, configuring each sheet to comprise a sheet edge disposed between a pair of sheet legs, defining a slit within each sheet leg, arranging the plurality of sheets of cardboard in a side-by- side layered fashion to form a block of corrugated cardboard material, providing a die-cut corrugated cardboard wrap-around carton member, forming at least one lip within the wrap-around carton member, enveloping the plurality of cardboard sheets with the wrap-around carton member, and interlocking the at least one lip the carton member with a longitudinally-extending slot that is formed by the slits that are defined within the plurality of layered cardboard sheets that substantially fill the carton member. 11. The method of claim 10 wherein the wrap-around carton member providing step further comprises the step of providing a carton member having a bottom floor, a front face portion, a rear face portion, a first side face and a second side face, the first side face further comprising a foldable extension portion and a leading lip, and the second side face further comprising a foldable extension portion and a leading lip. 12. The method of claim 11 wherein the leading lips of the first and second side faces are each receivable within a slot that is formed by adjacent slits defined within the plurality of sheets. 13. The method of claim 12 wherein each slit defined within each sheet is angled upwardly relative to the horizontal to capture the leading lips of the first and second side faces of the carton member.
