A content discharge mechanism for a container with a pump has a discharge outlet that is fixed in position. The device has an operation button and a cylindrical piston that move as one, as well as a ball valve that rests on a seat. The ball valve opens as the cylindrical piston retracts after an actuation to allow more fluid into the upstream passage chamber. A downstream passage with a valve for dispensation fluidly communicates with the upstream passage through a hole. As the cylindrical piston and its seal slide over the hole, the discharge from the downstream passage stops.
