A carafe has a flask and a lid assembly. The flask has a vessel. The lid assembly has a plug lid with an outlet port, a limiting bracket with a guiding channel and at least one outlet, and a sealing ball mounted in the guiding channel. The limiting bracket is mounted in the outlet port of the plug lid and is connected to the plug lid. When an opening of the vessel faces upward, the sealing ball slides downward to seal the outlet port of the plug lid. When the vessel tilts and the opening of the vessel faces downward, the outlet port of the plug lid is open, so that liquid in the vessel can flow out of the vessel. A user does not have to press or turn the lid assembly. Therefore, it is convenient to pour liquid out of the vessel.
