An attachment that is detachably mounted to a cartridge mounting unit of a printing apparatus, the cartridge mounting unit including a liquid introduction portion that receives a liquid, and a restricting mechanism that restricts a rotation movement of an incompatible cartridge in a rotation mounting direction to be mounted by interfering with the incompatible cartridge, the attachment including a release portion that releases restriction by the restricting mechanism by pushing a part of the restricting mechanism in a pre-determined insertion direction, and a maintaining portion that maintains a mounted state of the attachment in cooperation with the cartridge mounting unit.

Attachment and printing system

A cartridge including a first guide rib and a second guide rib that extend in the Y direction and project outward in the X direction. In an attachment state in which a cap is attached to the cartridge, the cap includes a sealing wall having a liquid holding portion that faces the liquid supply portion, a first projecting rib projecting in a direction opposite to a projecting direction of the first guide rib, a second projecting rib projecting in a direction opposite to a projecting direction of the second guide rib, a first recessed portion that is formed between the sealing wall and the first projecting rib and accommodates the first guide rib, and a second recessed portion that is formed between the sealing wall and the second projecting rib and accommodates the second guide rib.

Cap and cartridge unit

A cartridge includes a first operation surface that receives a first load for moving the cartridge in an inserting direction, a main surface that constitutes a top surface positioned on a side of an upward direction in a direction of gravity in an inserted posture, a second operation surface that constitutes the top surface in an inserted posture and is positioned on a side of a downward direction in the direction of gravity with respect to the main surface and that receives a second load for moving the cartridge in a rotational-attachment direction, in which an angle formed by the second operation surface and the inserting direction is smaller than an angle formed by the first operation surface and the inserting direction.

Cartridge

A technique for preventing a decrease in an amount of liquid contained in a cartridge is provided. The cartridge includes a liquid containing portion and a liquid supply portion. The liquid supply portion is coupled to the liquid inlet portion due to rotational movement of a containing-portion-rear-wall side of the cartridge downward around a rotation fulcrum, which is located on the insertion direction side, of the cartridge mounting portion. In the insertion direction, a first distance between a liquid flowing-in port and a rear wall inner surface, which is an inner surface of a containing portion rear wall, is shorter than a second distance between the liquid flowing-in port and a front wall inner surface, which is an inner surface of a containing portion front wall.

Cartridge and printing system

An ink refill container for refilling a printer having an ink inlet flow-path member with ink includes: a container body portion configured to store ink; and an ink-outlet forming portion coupled to the container body portion and having a cylindrical portion forming an ink outlet. The ink-outlet forming portion includes a valve disposed in the cylindrical portion and configured to be opened by the ink inlet flow-path member inserted in the cylindrical portion, and closed by withdrawal of the ink inlet flow-path member from the cylindrical portion; a sealing member disposed at the ink outlet and configured to be in contact with the valve in a closed state of the valve; a holder member configured to hold at least one of the valve and the sealing member; and a fixing portion configured to fix the holder member to the cylindrical portion.

Ink refill container

An amount of liquid that will be left in a cartridge without being consumed is reduced. The cartridge includes a liquid containing portion that contains the liquid; a front wall that is located on an insertion-direction side, an insertion direction being a direction of being inserted into the cartridge mounting portion; and a bottom wall that intersects the front wall and in which a liquid supply portion configured to be coupled to the liquid inlet portion is disposed.

Cartridge, printing system, and printing apparatus

A cartridge includes a liquid container and an adaptor. The liquid container has a liquid storage containing a liquid to be supplied to a printing apparatus, a liquid supply section configured to supply the liquid contained in the liquid storage to a liquid introduction section, and an adaptor mounting section. The adaptor is mounted on the adaptor mounting section and has a terminal placement section in which a cartridge-side terminal electrically connected to an apparatus-side terminal is disposed and an insertion aperture through which the liquid introduction section passes. The adaptor mounting section is provided with a mounting mechanism for mounting the adaptor, which has a predetermined constant shape.

Ink cartridge

There is provided an ink replenishment container for replenishing ink into an ink tank via an ink inlet flow path member, the ink replenishment container including a container main body, an ink outlet forming portion having a tubular portion, a spring valve having a valve body mounted in the tubular portion and a spring for urging the valve body toward the ink outlet, and a sealing member mounted in the tubular portion and having a sealing end configured to contact with the valve body in a valve close state, in which the sealing member has a cylindrical inner peripheral wall and an elastic membrane portion extending from the inner peripheral wall toward a center, and the elastic membrane portion is formed with a slit-shaped gap passing through a center portion including the center.

Ink replenishment container

A cartridge includes: a liquid accommodating portion; a liquid supply portion having a central axis and a supply portion flow path which communicates with the liquid accommodating portion; and a valve mechanism arranged in supply portion flow path, wherein the valve mechanism has a valve seat having an insertion port into which liquid introduction portion is inserted, a valve body having a closing surface which abuts on the valve seat to close the insertion port, and a biasing member biasing valve body toward the valve seat, the valve mechanism is opened by the valve body being pushed by the liquid introduction portion, and the closing surface has a flat surface portion, and an inclined surface portion formed around the flat surface portion and inclined toward an edge of the closing surface, and at least a part of the inclined surface portion faces the introduction portion flow path in mounted state.

A cartridge detachably mounted in a liquid ejecting apparatus including a liquid introduction portion includes: a liquid supply portion having a supply portion flow path; a valve seat having a valve seat insertion port; a valve body upstream of the valve seat; a biasing member biasing the valve body toward the valve seat; a cap located downstream of the valve seat; and a liquid absorbing material in contact with the cap, in which the cap has a first surface facing the valve seat, a second surface facing the first surface and contacting the liquid absorbing material, a cap insertion port formed over the first and second surfaces, into which the liquid introduction portion is inserted, a groove formed in the first surface and facing the valve seat, and a hole formed over the first and second surfaces and coupled to the groove, and liquid absorbing material is in the hole.

The cartridge includes a liquid containing portion containing a liquid, a liquid supply portion, an arrangement portion having a bottom wall in which an opening through which the liquid introduction portion is inserted is formed, and a film peelably attached to the arrangement portion while covering the opening portion, in which the arrangement portion further has a mounting element cooperating with the printing apparatus, and the film is arranged at a position where the film is interposed between the printing apparatus and the mounting element when a mounting process is performed in a state in which the film is attached to the arrangement portion.
