A container (2) for storing and dispensing a liquid comprises a chamber for holding a liquid, the chamber being defined by rigid chamber walls (4); a liquid outlet port (10) for dispensing the liquid from the chamber; and a gas port (20) configured to allow air into the chamber from the atmosphere outside the chamber only when the pressure outside the chamber exceeds the pressure inside the chamber by more than a predetermined threshold. When liquid is dispensed from the container via its outlet port, the pressure within the chamber will be reduced. When the pressure within the chamber falls below the external, ambient pressure by more than a predetermined amount, the gas port will open to allow air into the chamber from the atmosphere. This allows liquid to continue to be withdrawn readily from the container, by preventing a significant pressure differential from building up between the inside and outside of the chamber.

A manufacturing method of a liquid storage body includes: preparing a pre-restored storage body that has a bag to which a connection member is attached, and that is thereby sealed, the connection member being provided with a liquid outlet port, a storage-body-side electrical connection portion, a first receiving portion that receives a first positioning portion, and a second receiving portion that receives a second positioning portion; forming a communication portion that is in communication with the internal space of the bag by processing the bag; injecting a liquid from the communication portion into the internal space of the bag; and closing the communication portion so as to seal the bag.

A logic circuitry package for a replaceable print apparatus component comprises an interface to communicate with a print apparatus logic circuit, and at least one logic circuit. The logic circuit may be configured to identify, from a command stream received from the print apparatus, parameters including a class parameter, and/or identify, from the command stream, a read request, and output, via the interface, a count value in response to a read request, the count value based on identified received parameters.

A liquid discharge apparatus includes a head configured to discharge a liquid, and a discharge receptacle configured to receive the liquid discharged from the head at an installation position. The discharge receptacle includes a liquid holder configured to receive the liquid discharged from the head, and a support configured to detachably support the liquid holder. At least a part of the support is displaceable to a detachment position at which the liquid holder is detachable from the support, and the detachment position is lower than the installation position.

An engagement part fitted in an outer package of an ink cartridge is provided with: a fit-in rib which is provided at a circumferential edge on a rear side and which serves as a guide upon engagement with an opening of the outer package; an engagement rib provided upright at the circumferential edge of the engagement hole in the same direction as a direction of the fit-in rib; and a bonding region for bonding a communication tag that performs near field radio communication with a printer. A tag-removing hole which is formed in the bonding region and which is to be removed from a bonding surface side of the communication tag with a bar-like member inserted is formed in a formation region as the bonding region located in a first quadrant and a fourth quadrant in an orthogonal coordinate system.

A liquid circulation device includes a housing having an outlet and an inlet, a circulation unit configured to convey liquid out of the housing through the outlet and recover liquid into the housing through the inlet, a liquid supplying unit configured to supply liquid into the housing, an air conveying unit configured to convey air into and out of the housing, a level detecting unit configured to detect a level of the liquid in the housing, a pressure sensing unit configured to detect a pressure of the air in the housing, and a control unit configured to control a pressure of the liquid in the housing by controlling the liquid supplying unit or the air conveying unit, based on the level and the pressure of the air.

A tank includes: a wall separating a liquid storage chamber, which stores a liquid to be supplied to a liquid consuming part, from an outside; an inlet penetrating the wall; and a liquid outflow part which allows the liquid to flow to the outside of the liquid storage chamber. The wall includes a view wall, which extends upward and downward and allows a user to visually check a liquid level in the liquid storage chamber, and a bottom wall, which defines an inner bottom surface of the liquid storage chamber by being connected to the view wall. The inner bottom surface of the bottom wall includes an inclined part which extends from at least a part of the view wall to incline downward in a direction away from the view wall.

In an authenticity determination system, an image forming apparatus acquires apparatus identification information for identifying the image forming apparatus from a memory of the image forming apparatus, and consumables container identification information for identifying a container of predetermined consumables from the container of the consumables mounted in the image forming apparatus. A server stores the apparatus identification information and the consumables container identification information in association with each other, receives the apparatus identification information and the consumables container identification information transmitted from the image forming apparatus, and determines whether the received apparatus identification information and the received consumables container identification information are stored in association with each other. When the information on the determination is affirmative, the image forming apparatus executes printing based on output source identification information including the apparatus identification information and the consumables container identification information on an output using the predetermined consumables.

A liquid discharge cartridge manufacturing method includes a first step of individually shaping a first shaped member and a second shaped member that form a housing of a liquid discharge cartridge, and a second step of joining the first shaped member and the second shaped member to be bonded to each other with molten resin. The first step includes shaping a wall section in the first shaped member, the wall section forming a recess for accommodating the molten resin, and shaping a projection in the second shaped member, the projection extending such that the projection is located at the outer side of the wall section and adjacent to the wall section, with a predetermined gap being formed between the projection and the wall section, when the first and second shaped members are joined.

A cartridge detachably attachable to an apparatus body of an image forming apparatus that forms an image on a recording medium in which a memory unit is fixed by an inexpensive adhesive member that can control adhesion force. The cartridge includes: a memory; and a memory support member that supports the memory. The memory has a semiconductor device storing information related to a cartridge, a sealing material that protects the semiconductor device, and a cartridge electrical contact configured to be electrically connectable to a body electrical contact of the image forming apparatus body for transferring information on the semiconductor device to the image forming apparatus body. The sealing material and the memory support member contain the same type of a thermoplastic resin, the sealing material and the memory support member have bonding faces, and at least parts of the bonding faces are welded and fixed by a solvent.
