Abstract: A mixing paddle is described comprising a first section (2) adapted for mixing a paint, and a second section (3) having at least one removing edge (4), wherein the removing edge (4) has a geometry complementary to a horizontal cross section (5, 6) of the first section (2), and wherein the second section (3) is detachably attached, and a corresponding method for removing excess paint from a mixing paddle is described.
Abstract: A lid (2) for a reservoir (1) to be connected to a liquid spraying device, comprising a ventilation hole (3); a flexible tube (4); and a valve (5), wherein the combination of the ventilation hole (3), the flexible tube (4), and the valve (5) forms a ventilation system which allows an air movement from the outside of the reservoir (1) via the ventilation system to the inside of the reservoir (1) while it blocks the movement of a liquid (6) from the inside of the reservoir (1) via the ventilation system to the outside of the reservoir (1).
