ABSTRACT OF THE DISCLOSURE The invention relates to a container (1) for the spray- dispensing of liquid (2), having spray nozzle (D) arranged on the head side of the container (1) and a handle (14) for a pump (P) associated with the container, which pump has pump cylinder (6), piston rod (16) and pump cylinder for the production of a cushion of compressed air above the surface of the liquid (8), and, in order to obtain a structural shape which is free of residual pressure and avoids a springing back of the piston rod (16), it proposes that the pump cylinder (6) at its lower end forms a pressure-relief opening (35) which can be moved over by the sealing surface of a cuff (22) which forms the pump piston, said opening being in flow communication with an outwardly open tube cross section (17) of the piston rod (16) when the pump piston (22) is in depressed position.
