The fertilizer container consists of a bottle-shaped receptacle (1) having inlet and outlet openings (3, 2). The inlet opening (3) is provided with an automatic non-return valve (8) comprising a valve element (10) formed by a fixed external ring (15) and by a movable internal disc (17) connected to the external ring (15) by two diametrally opposite flexible tabs (18), which allow the momentary deformation of the movable disc (17) when the inlet opening (3) is fed with a water flow coming from the water supply system, while preventing any opposite flow. <IMAGE> |
