Claims

[Scope of utility model registration request]

The upper and lower corners of the cylindrical body are provided with fittings on both sides, and bent pieces that protrude vertically symmetrically from one side of the front and rear walls to the other in a step-like manner with side edge numbers and steps, are provided at the top and bottom of the cylindrical body. In a multilayer paper bag in which the opening is formed by folding the outer layer inward to form an inlet, and the opening and bottom are closed by symmetrically pasting both folded pieces to the front and rear walls, A multi-layer paper bag having an air inlet in which a valve paper for the air inlet is made to protrude outward from a protrusion of a protruding piece of an inner layer cylinder which protrudes from the outer folded piece of waste paper so as to cover the folded piece.
