A supply unit in which a liquid container including a coupling portion being detachably mounted includes: a liquid introduction unit coupled to the coupling portion of the liquid container; an urging member that urges the liquid container in an uncoupling direction which is a direction opposite to a coupling direction, the coupling direction being a direction in which the liquid container is coupled to the liquid introduction unit; and an engagement lever having an engaging portion that engages with the liquid container when the liquid container is coupled to the liquid introduction unit, the engagement lever includes an operating portion operated by a user and a pressing portion configured to press the liquid container and is configured to release the engagement of the engaging portion with the liquid container when the operating portion is operated and to press the liquid container in the uncoupling direction by the pressing portion.

The object is to provide a liquid container capable of supplying liquid to a liquid ejection apparatus with simple configuration. Liquid container 100 has liquid containing bag 120 and an introduction member. The introduction member includes the first and second liquid introduction members. The first introduction member has the first spacer unit and the first coupling unit integrally connected to the first spacer unit in which the first groove for letting liquid flow to a liquid lead-out unit is formed. The second introduction member has the second spacer unit and the second coupling unit integrally connected to the second spacer unit in which the second groove for letting liquid flow to the liquid lead-out unit is formed. The first and second liquid introduction members are adjoined so that the surface on which the first groove is formed and the surface on which the second groove is formed face each other.

A recording apparatus includes a recording head configured to discharge a liquid, a first liquid reservoir unit configured to store the liquid to be supplied to the recording head, a liquid supply port configured to supply the liquid stored in the first liquid reservoir unit into the recording head, a liquid supply path connecting the first liquid reservoir unit and the liquid supply port, a second reservoir unit, in the recording head, configured to store the liquid supplied from the liquid supply port, and a holding unit configured to hold the liquid supplied from the second reservoir unit, in the recording head, wherein the second reservoir unit includes an opening provided upward in a direction of a gravitational force with respect to the liquid supply port and is configured to supply the liquid to the holding unit, when the recording head is in a posture of performing recording.

A liquid absorber of the present disclosure includes: a first base material; a second base material; and an absorption layer provided between the first base material and the second base material, in which the first base material and the second base material both contain a flame-retardant filament nonwoven fabric, and a content of a flame retardant in the absorption layer is less than 10% by mass.

An ink cartridge includes an ink chamber that stores ink. A protruding chamber protrudes upward from the ink chamber in a gravitational direction when the ink cartridge is used. A swing body has a float and a detection portion, and a detection chamber in which the detection portion moves and with which an amount of ink stored in the ink chamber is detected in accordance with a position of the detection portion. In the ink cartridge, a pivot center of the swing body that pivotally moves is disposed inside the protruding chamber.

A liquid ejection apparatus includes a housing provided at least with an upper surface and side surfaces, and a liquid tank that is arranged in the housing and is refillable with a liquid from outside. A display unit that indicates a remaining liquid amount in the liquid tank is arranged at least at one of joining portions each joining the upper surface to one of the side surfaces.

A recording apparatus 101 includes a liquid storage portion 46 configured to store liquid, a recording head 22 that ejects liquid supplied from the liquid storage portion 46 onto the medium, and a light emitting unit 301 configured to emit light, wherein the liquid storage portion 46 has a float 48 configured to float on liquid in the liquid storage portion 46 and to move according to movement of liquid surface LS while maintaining a posture, and a front surface 43F in which the liquid in the liquid storage portion 46 is visually checkable from outside the liquid storage portion 46, wherein the float 48 has a front surface 48a that by receiving the light from the light emitting unit 301, appears luminous when viewed from a direction facing the front surface 43F.

A pressure fluctuation suppression device including a suppressor and a detector. The suppressor is disposed on a flow path of a liquid and suppresses fluctuations in pressure of the liquid in the flow path. The detector detects deterioration of a suppression function of the suppressor.

A printing-fluid cartridge is inserted into a prescribed insertion space of a cartridge-attachment section in an insertion direction crossing a gravitational direction to be attached thereto in an attached posture. The printing-fluid cartridge includes: a housing including a storage chamber, a supply portion having a supply hole, an electrical interface disposed at an upper surface of the housing, and an interfering surface. The interfering surface is positioned upward of the storage chamber and extends in a widthwise direction of the housing. The interfering surface is positioned downward and frontward relative to the electrical interface and is configured to abut against a projection provided at another insertion space different from the prescribed insertion space of the cartridge-attachment section during an insertion of the printing-fluid cartridge into the another insertion space.

An inkjet printer includes a printer body and an ink container provided in the printer body. The ink container includes an ink containing portion, a frame portion and a cover portion. A top portion of the ink containing portion includes a port. The cover portion is pivotally connected to the frame portion and pivotable between an opened position, in which the port is exposed, and a closed position, in which the cover portion covers the port, with respect to the frame portion. The cover portion includes a sealing member provided corresponding to the port on an opposing surface of the cover portion. When the cover portion is in the closed position, the sealing member seals the port, and when the cover portion is in the opened position, the sealing member is separated from the port.
