A fluid container includes a support body having a reservoir for accommodating fluid, and a nozzle body attached to the support body. The support body has a lid for closing the reservoir. The nozzle body includes: a formation unit for forming an opening through the lid; a pipe communicating with the opening for permitting passage of the fluid; and a discharge port communicating with the pipe for discharging the fluid. In a first state, the formation unit and the lid are separated as the nozzle body and the support body are engaged. In a second state, the opening of the lid is formed as the nozzle body moves in a direction to approach the support body from the first state. In a third state, at least a part of the formation unit and the lid are separated as the nozzle body moves in an opposite direction from the second state.
