A liquid container detachably mountable to a mounting portion of an ink jet recording apparatus, the liquid container including a casing defining a liquid containing chamber, an electrical contact, a light emitter, a display portion for directing emitted light to an outside of the liquid container, and an information storing portion for storing information relating to the liquid container. First and second engaging portions are engageable with respective first and second locking portions of the mounting portion, and are disposed at opposite first and second sides of the casing. A latch lever displaceably supports the second engaging portion away from the second side. A supply port is provided on a third side of the casing between the first and second sides, the electrical contact is disposed at a corner between the second and third sides, and the display portion is disposed adjacent an upper portion of the second side.

Liquid container and manufacturing method therefor

A liquid container detachably mountable to a mounting portion of an ink jet printer including an information storing portion for storing information relating to the liquid container; a controller controls light emission of a light emitting portion, based on individual information corresponding to the ink container, supplied through a container contact from a printer contact, and the discrimination information stored in the memory; a light guide member having a light incident portion and a light emergence portion, the light guide member configured to guide the light entered from the light incident portion to the light emergence portion so as to cause a light receptor to receive the light emerged from the light emergence portion to obtain light reception information used for discriminating properness of position of the ink container mounted in the mounting portion.

A liquid container detachably mountable to a mounting portion of an ink jet recording apparatus, and which includes a liquid chamber, a light emitter, an electrical contact which receives a signal for light emission by the light emitter, and a display portion which directs emitted light from the light emitter toward an outside of the liquid container. A latch lever is elastically deformable and has a latching portion spaced from a first side of the liquid container, the first side being between the latching portion and the liquid chamber. A liquid supply port is disposed at a second side of the liquid container. The electrical contact is disposed at a position which is between the latching portion and the liquid supply port as seen facing both of the first and second sides, and the display portion is disposed adjacent to an upper portion, in use, of the first side.

The present invention provides a method for producing an ink jet recording cartridge provided with a recording element substrate on the bottom surface, wherein the cartridge can be integrated with the recording element substrate precisely without causing any damage on the substrate, has a high barrier capacity, and can work with various inks and wherein such characteristics of the cartridge are provided by including the steps of pressing a lid to the upper opening of an ink-holding container made of a resin material including glass fibers to cover the opening, and vibration welding the lid to the container where means for holding the lid is vibrated in the direction along the top surface of the container.

Cartridge for ink jet recording and method for producing the same

A liquid container detachably mountable to a mounting portion of an ink jet recording apparatus in a slot-like mounting configuration where the liquid container is supported between a pair of engaging portions that respectively engage with a corresponding pair of locking portions on the mounting portion of the recording apparatus. The liquid container is supported in an upright configuration and includes a display portion on an upper side thereof, and a light emitting portion which emits light for display by the display portion. Because the display portion is disposed on an upper side, a user can confirm the display despite the mounting arrangement of the liquid container in the recording apparatus.

An ink container for supplying through an ink supply port ink accommodated in a main body of the container, the ink container including a substrate mounted on a surface of the main body of the container, and a contact portion and a storing element electrically connected with contact the portion, the contact portion and the storing element being provided on the substrate, Characterized In That the contact portion is disposed at a position more remote from the ink supply port than the storing element.

Ink container and ink container holder

An ink jet recording head cartridge has a liquid container for retaining a liquid, a discharge circuit section which comprises a supply port for receiving the liquid in the liquid container, a nozzle in communication with the supply port, and a discharge energy generating element, provided in the nozzle, for discharging the liquid; and a flow path for leading the liquid from the liquid container to the discharge circuit section, wherein the flow path comprises a vertical portion extending from a portion connecting to the ink container, and a horizontal portion connecting to a lower end of the vertical portion and connecting to the supply port of the discharge circuit section, a throttle portion whose width becomes narrower in a supply direction of the liquid is formed in a portion, which connects to the vertical portion, of the horizontal portion of the flow path, and a groove shaped flow path whose width is narrower than the total width of the flow path is contiguously formed on an inner wall of the flow path from a portion connecting to the liquid container to a portion connecting to the discharge circuit section.

Ink jet recording head cartridge

A liquid container containing ink, which is detachably mountable to a carriage, the improvement residing in the provision of an optical medium to which information is writable using visible light and from which the information is readable.

Liquid container and recording apparatus

A package includes a packaging member; and an ink container which contains ink comprising pigment coloring material and solvent dispersing the coloring material and which has an ink supply port for permitting supply of the ink to an outside, wherein the ink container is mountable to an ink jet recording apparatus with the ink supply port at a lower position, the ink container accommodating an ink absorbing material for absorbing the ink and being provided with an air vent which is open for fluid communication between a space inside the ink container and ambience, and wherein a region tending to have a high coloring material density in the ink container is at a position generally diagonally opposite the ink supply port, wherein the ink container is in a first orientation which is different from a second orientation taken in use in the ink jet recording apparatus.
