<p>A flat end closure arrangement for a thermoplastic coated paperboard container, and the blank therefor, wherein four sets of dual, oppositely skewed, supplementary score lines (82, 84, 86, 88, 90, 92, 94, 96) are formed on two sides of the resultant end closure, such that they are adapted to be folded into position just inside the usual horizontal score lines (16) separating the end closure panels from the sidewall panels. These supplementary score lines provide a second, substantially 90o bend for the paperboard layers, supplementing a 90o bend about the respective horizontal score lines, in lieu of each usual 180o bend about the respective horizontal score lines, thereby diminishing the chances for cracking of the thermoplastic coating at the bend locations.</p> |
