Abstract: A stackable plastic container includes a hollow body formed of a base, upstanding side walls connected to the base and a top wall with a filling and/or pouring neck, the peripheral edge of the top wall connecting onto the side walls at a shorter distance from the base than the filling and/or pouring neck, and a stacking attachment piece which has a lower bounding plane fitting onto the top wall as well as an upper surface complementary to the base of the hollow body and lying above the filling/pouring neck. Because the filling/pouring neck lies higher than the peripheral edge of the top wall, 100% emptying of the container is always gauranteed. The attachment piece enables stacking because the space between the top wall of the hollow body and the base of a hollow body of another container above it is occupied by the attachment piece.
