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 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

When a known lid member was merely applied to a bottle that contains ink, there was room for improvement in terms of the operation of the lid member and the way how to bring attention to the handling thereof. A bottle set is provided that includes: a bottle that includes an ink container that contains ink, and an outflow port through which the ink in the ink container flows out to the outside; and a lid member that is configured to attach to and detach from the bottle, and is configured to cover the outflow port in a state of being attached to the bottle. The lid member includes a colored portion that has optical transparency and is colored with a color corresponding to a type of the ink contained in the ink container in at least a portion of the lid member.

Bottle set and bottle

Convenience of an ink bottle and a bottle set is improved. An ink bottle includes: a container portion that contains ink; a guiding portion that is formed in one end portion of the container portion, and includes an outflow port from which the ink in the container portion flow out; and a cover that covers at least an end portion of the container portion on the opposite side of the guiding portion.

Ink bottle and bottle set

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.

A cartridge includes: a liquid containing body including a liquid containing portion containing the liquid and a liquid supply portion; and an adapter attached to the liquid containing body and including a terminal arrangement portion which is located on one end side of the adapter in a longitudinal direction and in which a cartridge-side terminal electrically coupled to the apparatus-side terminal is arranged, and an insertion opening portion through which the liquid introduction portion is inserted, in which the adapter has a notch located between the terminal arrangement portion and the insertion opening portion in the longitudinal direction.
