A liquid container includes: a bag that contains a liquid; and a pair of members configured to be reused when the liquid container is reassembled by replacing the bag used. The pair of members are fixed to each other by one or more swaging pins.

A liquid container to be mounted in a liquid ejection apparatus contains liquid to be ejected from the liquid ejection apparatus. The liquid container comprises a liquid container bag containing liquid, at least one tube arranged in the inner space of the liquid container bag and having the first end open to the inner space, a connection member fitted to the aperture of the liquid container bag and connected to the second end of the tube and a holding member supported by the connection member and arranged in the inner space to hold the tube, the holding member having at least a groove for receiving the tube to be fitted thereinto at a position thereof other than the second end thereof. The holding member can integrally be molded.

There is provided a liquid ejecting head including: first and second nozzle rows extending in a first direction; a first supply flow path; a first filter chamber having a first inlet; and a second filter chamber having a second inlet, in which the first and second nozzle rows are shifted from each other in both the first direction and a second direction orthogonal to the first direction, the first supply flow path has a branch flow path for distributing the liquid between the first filter chamber and the second filter chamber at a branch position, the branch position is disposed between the first filter chamber and the second filter chamber in a plan view, and the first and second inlets are disposed at a part where the first filter chamber and the second filter chamber overlap each other when viewed in the second direction.

An ink pack configured to supply an ink to an ink-consuming apparatus includes a first pack configured to contain the ink, an ink supplying section provided to the first pack, the ink supplying section being configured to supply the ink to the ink-consuming apparatus, and a second pack configured to accommodate the first pack. The first pack and the second pack are separable.

The present disclosure refers to a method of monitoring a fluid supply system, the system including a collapsible fluid reservoir to contain a supply of fluid and an outer container to enclose the collapsible fluid reservoir and to receive pressurized gas that pressurizes the supply of fluid, the method comprising a controller to: control a gas pressure pump to feed the fluid to or from the fluid reservoir, the gas pressure pump operating in pressurization cycles; monitor a parameter of the pressurization cycles; and determine a fill state of the fluid reservoir as a function of the monitored parameter.

There is provided a mounting mechanism for a liquid container capable of suppressing a damage of a mouthpiece and enabling efficient stirring, and there is provided an ink stirring method for an ink cartridge using the mechanism.

The mounting mechanism for a liquid container includes: a holder portion that fixes a mouthpiece serving as an outlet of a liquid of a liquid container in which the liquid is contained and that holds the liquid container; a set portion that has a fitting part fitted to the mouthpiece and causing the liquid to flow out of the mouthpiece; a tube that communicates with the fitting part; and a main body that is connected to the set portion by using the tube, in which the set portion is movable with respect to the main body.

To provide an ink cartridge capable of accomplishing satisfactory electrical connection relative to a printer main assembly. An ink cartridge 1 detachably mountable to a cartridge mounting portion 33 provided with an ink receiving tube 52 and a plurality of electrical connecting portions 55, the ink cartridge 1 including a tube inserting portion 8 into which the receiving tube 52 is insertable, a substrate 3 provided on a front side 2c in a position above the tube inserting portion 8, a plurality of electrical contacts 4 electrically connectable with the plurality of electrical connecting portions 55, the electrical contacts 4 being arranged on the substrate 3 in a direction crossing with a direction from a bottom surface 2b toward an upper surface 2a

There is provided a technology which can improve the mounting posture of a liquid ejection apparatus when mounted to a liquid container. The liquid container is flexible and includes a storage portion configured to store the liquid and a connection member. The connection member is provided with a liquid outlet which is inserted with a liquid introduction portion, a container-side electrical connector which makes electrical contact with an apparatus-side electrical connection unit while receive at least +Z direction force from the apparatus-side electrical connection unit, a first receiver configured to receive a first positioning portion, a second receiver configured to receive a second positioning portion, and a recess which houses a protrusion of the case. The recess and the container-side electrical connector are formed at positions which at least partially overlap each other when viewed from a Z direction in a mounting state. In the mounting state, the width of the liquid container in the Z directions is larger than the width in the Y directions and the width in the X directions.
