A cartridge configured to be mounted in and detached from a cartridge mounting portion of a printing device including a liquid introduction portion that receives a liquid and a device side valve body that opens/closes an introduction portion flow path which is a flow path of the liquid introduction portion, the cartridge comprising:
- a liquid containing portion that contains the liquid;
- and
- a liquid supply portion that has a supply opening formed at a tip, communicates with the liquid containing portion, is coupled to the liquid introduction portion, and includes a cartridge side valve mechanism that opens/closes a supply portion flow path which is the flow path of the liquid supply portion, wherein
- the cartridge side valve mechanism includes
- a cartridge side valve seat in which a cartridge side valve hole is formed,
- a cartridge side valve body that stops the cartridge side valve hole and has a tip surface positioned on a side of the supply opening, and
- a cartridge side urging member that urges the cartridge side valve body in a direction toward the cartridge side valve seat,
- the cartridge side valve body has a protrusion that protrudes from the tip surface and pushes the device side valve body to open the device side valve body, and
- when the cartridge is mounted in the cartridge mounting portion, the protrusion protrudes inside the device side valve body into the introduction portion flow path.
A printing device in which a cartridge is mounted, the cartridge including a liquid supply portion and a cartridge side valve body for opening/closing a supply portion flow path which is a flow path of the liquid supply portion, the cartridge side valve body having a protrusion that protrudes from a tip surface, the printing device comprising:
- an ejecting head that ejects a liquid;
- and
- a cartridge mounting portion in which the cartridge is mounted and which includes a liquid introduction portion coupled to the liquid supply portion and receiving the liquid, wherein
- the liquid introduction portion has an introduction portion opening formed at a tip, an introduction portion flow path which is a flow path, and a device side valve body that opens/closes the introduction portion flow path,
- the device side valve body is arranged at a position at which the device side valve body is pushed by the protrusion to be opened, and
- when the cartridge is mounted in the cartridge mounting portion, the device side valve body receives the protrusion inside the device side valve body into the introduction portion flow path.
