The container is formed by three equal rectangular walls (1) forming a containing body. Said container body has equilateral triangular openings, to be closed with self-centering effect, each opening being formed by three equal triangular sectors (2) extending from the fold line (3) of each wall (1) and characterized by a bigger side (4) and a smaller side (5). The closure is actuated by finger pressure on the self-centering sectors (2). In this way, each smaller side (5) is locked under a corresponding bigger side (4).
