摘要 The present invention relates to a Refuse bag made of paper comprising a front, wider and rear wider wall (3,4) having mutual substantially the same width, and two side walls(2) to be fold in between said front and rear walls (3,4), whereby the rear wall (4) is drawn up to a level above the front wider wall (3), whereby a folding line (9) is arranged across the rear side wall (4) substantially in level with the upper edge of the front side wall (3) to the formation of a lid (10) to be able to provide for a simple folding around of this lid (10) to said front side wall (3), that the side walls (2) further are drawn up to a level over the wider front wall (3) to reach up to 25 to 65% of the level of the wider rear wall (4), whereby said folding line (9) moreover is present on the side walls (2) in level with the upper edge of the front wall (3), and that an adhesive layer (5) is distributed over at least two surfaces with at least one non-adhesive slit (11) between these surfaces on either the lid (10) or on the wider front wall (3), whereby the adhesive layer (5) reaches substantially at least from the upper edge of the lid (10) until the upper edge of the drawn up side walls (2) or substantially at least from the upper edge of the wider front wall (3) to a line corresponding a folded lid (10) to the wider front wall (3), whereby the slit (11) forms an air valve comprising 25 to 65% of the width of the bag to allow release of air after a closure.
