Abstract
Abstract A waterproof corrugated board construction for use in the Hydrocooling process for preparation of produce and/or fruit shipped in a container formed of the corrugated board. The box construction using the corrugated board comprises a combination of a corrugated sheet having attached to the crest of the corrugation at least one substantially flat waterproof lining with the construction also containing a coating of a deformable waterproof composition and having the edges of the corrugated sheet compressed and retained by the action of the deformable composition in an amount sufficient to seal the edges from entry of water during the Hydro-cooling process. Also disclosed is a method for providing a liquid sealed box from the corrugated board construction. In addition, there is disclosed an improved cutting die for use in forming the waterproof box blank described herein.

Claim 1
Independent Claim
166 words
A WATERPROOF CORRUGATED BOARD CONSTRUCTION COMPRISING, IN COMBINATION: A. A CORRUGATED SHEET HAVING ATTACHED TO THE CREST OF THE CORRUGATION ON AT LEAST ONE SIDE THEREOF AT LEAST ONE SUBSTANTIALLY FLAT WATERPROOF LINING SHEET, SAID CORRUGATED SHEET AND SAID LINING SHEET ALSO HAVING FORMED THROUGHOUT A PLURALITY OF HOLES EXTENDING COMPLETELY THROUGH SAID CORRUGATED SHEET AND SAID LINING SHEET; B. SAID CORRUGATED SHEET HAVING FORMED THEREON, BETWEEN SAID CORRUGATED SHEET AND SAID WATERPROOF LINING SHEET, A COATING OF DEFORMABLE WATERPROOF COMPOSITION; AND C. THE EXPOSED EDGES OF THE CORRUGATED BOARD AS WELL AS THE EXPOSED EDGES OF THE HOLES IN THE CORRUGATED BOARD BEING COMPRESSED AN AMOUNT SUFFICIENT TO COMPRESS THE CORRUGATED SHEET AND THE LINING SHEET AGAINST THE DEFORMABLE WATERPROOF COMPOSITION SO THAT THE HOLDING CHARACTERISTICS OF THE COMPOSITION WILL SERVE TO HOLD THE COMPRESSED SHAPE OF THE SHEET EDGES AS WELL AS AROUND THE EDGES OF THE HOLES THEREBY SEALING THE EDGES AGAINST THE ENTRY OF WATER BETWEEN THE LINER AND THE CORRUGATED SHEET.
