<p>PROBLEM TO BE SOLVED: To provide a stretching-type paper pack with simple and efficient disposal to eliminate such inconvenience that most of paper packs have been disposed by appropriately folding, tying or cutting the packs for stacking flatly, requiring long processing time and a large space. SOLUTION: Intermediate folds 7 and outer folds 8 are provided on required portions of a paper board with heat-bonding synthetic resin layers 10 provided on both faces to provide a cube, while a cap 2 equipped with a vent hole 3 is attached to a surface of an upper lid 1. At the time of disposal, the cap 2 is loosened and a push-in point 5 indicated on a body is pushed toward the center while adjusting an intake-and-exhaust of air, the pack is formed like a contracted accordion, thereby providing the compact pack.</p> |
