Claims15
A liquid storage container for replenishing a liquid ejecting apparatus with liquid comprising:
- a storage portion configured to store liquid;
- a discharge port unit including a discharge port through which liquid stored in the storage portion is discharged, a flexible member, and a stopping member configured to close a flow passage through which the discharge port communicates with the storage portion, wherein the discharge port, the flexible member, and the stopping member are arranged in this order;
- and
- a cover portion configured to be attachable and detachable to the discharge port unit and to be capable of opening and closing the discharge port,
- wherein, the stopping member has a surrounding portion and a recess portion in a center of the surrounding portion,
- wherein, both the surrounding portion and the recess portion move to a side of the storage portion after a communication flow passage included in the liquid ejecting apparatus penetrates the flexible member, whereby the discharge port is brought into fluid communication with the storage portion.
A recording unit including a liquid ejecting apparatus and a liquid storage container for replenishing the liquid ejecting apparatus with liquid wherein
- the liquid storage container comprises:
- a storage portion configured to store liquid;
- a discharge port unit including a discharge port through which liquid stored in the storage portion is discharged, a flexible member, and a stopping member configured to close a flow passage through which the discharge port communicates with the storage portion, wherein the discharge port, the flexible member, and the stopping member are arranged in this order;
- and
- a cover portion configured to be attachable and detachable to the discharge port unit and to be capable of opening and closing the discharge port,
- wherein, the stopping member has a surrounding portion and a recess portion in a center of the surrounding portion,
- wherein both the surrounding portion and the recess portion move to a side of the storage portion after a communication flow passage included in the liquid ejecting apparatus penetrates the flexible member, whereby the discharge port is brought into fluid communication with the storage portion;
- and
- wherein the communication flow passage includes two flow passages extending parallel to each other in a vertical direction in an interior of the communication flow passage and is configured to allow the liquid in the liquid storage container to be poured into a liquid tank which the liquid ejecting apparatus has by means of gas-liquid exchange.
