A cap capable of sealing a nozzle by two methods and a droplet discharge apparatus using the cap. When the cap is pressed onto a nozzle surface with the nozzle aligned with a center of a covering portion, a lip continuously contacts the surrounding of an opening of the nozzle, thereby forming a sealed space on the surface formed with the opening of the nozzle. Although ink in the nozzle may dry when left for a long time, no influence on ink discharge operation immediately after the cap is detached is expected since the cap does not directly seal the opening. When the cap is pressed onto the nozzle surface with the nozzle aligned with a center of a sealing portion, the substantially flat sealing portion seals the opening, thereby effectively preventing drying of ink, although there may be an influence on discharge operation immediately after the cap is detached.
