Provided is a liquid container attachable to a printing apparatus and configured to contain a liquid to be supplied to the printing apparatus, including: a container chamber configured to contain the liquid; a supply unit provided on a tip end side in a direction of attachment to be attached to the printing apparatus and configured to connect the container chamber to the printing apparatus; and a liquid holding unit provided to an inner peripheral surface of the supply unit and capable of holding the liquid by using a capillary force, the liquid leaking out in a case of attaching and detaching the liquid container to and from the printing apparatus, in which a length of the liquid holding unit in the direction of attachment of the liquid container is larger than a length of the liquid holding unit in a direction intersecting with the direction of attachment.

Liquid container and printing apparatus

A liquid storage container attachable to and detachable from a recording apparatus includes: a liquid storage bag that includes a supply port for supplying liquid to a port to be supplied of the recording apparatus and is configured to store liquid; an opening and closing body movable between an open position that allows liquid to be supplied from the supply port to the port to be supplied and a closed position that closes the supply port; a handle configured to move the opening and closing body between the open position and the closed position; and a lock mechanism configured to lock the opening and closing body in the closed position so as to permit the opening and closing body to move to the open position only when the liquid storage container is in an attached state in which the liquid storage container is attached to the recording apparatus.

Liquid storage container and recording apparatus

Provided is a technique in which liquid leaking in attachment and detachment of a liquid storage container to and from a printing apparatus can be retained with a simple, space-saving configuration. The liquid storage container can be attached to the printing apparatus. The liquid storage container includes a storage portion that stores the liquid, a supply port that supplies the liquid stored in the storage portion to the printing apparatus, and a liquid retaining portion that is capable of retaining the liquid leaking in the attachment and detachment of the liquid storage container to and from the printing apparatus by using capillary force. The liquid retaining portion extends along an outer peripheral surface of the supply port, in an attachment direction in which the liquid storage container is attached to the printing apparatus.

Liquid storage container and printing apparatus

A liquid storage container capable of storing liquid containing a precipitation component and externally supplying the liquid allows the liquid to be externally supplied to have a uniform precipitation component concentration. The liquid storage container can store liquid containing a precipitation component and externally supply the liquid and includes a storage portion that stores the liquid, a supply port that opens to the outside of the storage portion, a pipe having one end connected to the supply port and the other end connected to a suction port that opens to the inside of the storage portion, and an agitation member provided near the suction port for agitating the liquid stored in the storage portion.
