At the edges the side walls (3) are connected to each other, the side walls (3) penetrability in the lower part being greater than in the upper part. On the whole, the side walls (3) have three sections (7, 8, 9) with varied penetrability, such sections (7, 8, 9) preferably forming strips passing parallel to the bottom (2). The varied penetrability strip-shaped sections (7, 8, 9) are formed due to varied diameter perforation holes and/or due to varied number of perforation holes per area unit.;EFFECT: ensuring better quality and taste of brewed coffee.;7 cl, 1 dwg
