A container for accommodating a content of powder or a liquid includes an accommodating portion for accommodating the content; a top end portion including a discharging portion and a shielding member, wherein the discharging portion includes a discharge opening for discharging the content to an outside of the container and a passage for permitting passing of the content toward the discharge opening, and the shielding member shields the discharge opening; and a cap detachably mounted to the top end portion, wherein the cap includes a main body portion covering at least a part of the top end portion and a fixing portion fixed to the top end portion and connected to the main body portion, and wherein the main body portion of the cap is separated from the fixing portion by being rotated about a rotational axis thereof relative to the top end portion.

Disclosed is a liquid storage container comprising a liquid reservoir part holding liquid, an air communication part including an air communication port communicating with the atmosphere, an inner port communicating the liquid reservoir part with the air communication part, a seal member closing the inner port from the inside of the air communication part, a first biasing member biasing the seal member in a first direction from a first position away from the inner port toward a second position of closing the inner port, and a pressure receiving part including a protruding portion protruding from the air communication port to the outside of the air communication part, and joined to the seal member or the first biasing member. The seal member is separated from the inner port when the protruding portion of the pressure receiving part is pushed in a second direction opposite to the first direction.

There is provided an ink replenishment container for replenishing ink into an ink tank via an ink inlet flow path member having a plurality of flow paths, the ink replenishment container including a container main body, an ink outlet forming portion, and an outlet valve unit. The outlet valve unit includes a valve housing mounted to provide a gap with an inner peripheral surface of a tubular portion in the tubular portion, a sealing member, and a valve body movable between a valve close state in contact with the sealing member and a valve open state separated from the sealing member. The valve body has a partition contact portion capable of contacting a partition of the ink inlet flow path member. The valve housing has a through-hole that communicates with the gap, and the through-hole communicates with the ink inlet flow path member in the valve open state.

A liquid housing container includes a container main body including a housing chamber for housing liquid therein; and a feeding port for feeding the liquid to the housing chamber, and a plug member that is attachable to and detachable from the container main body and seals the feeding port, the plug member including a cover portion for covering the feeding port from an outer side of the container main body in a mounting state, in which the plug member is mounted to the container main body, and a protruded portion that protrudes from the cover portion to an inner side of the feeding port. The protruded portion includes a liquid holding portion that is provided at a position including a distal end surface of the protruded portion and is capable of holding the liquid by capillary force.

An ink cartridge includes a main body, a head part, a first hole, a label, and a second hole. The main body stores ink. The head part is provided on the main body and has a plurality of nozzles for ejecting ink. The first hole has a tapered shape which narrows from an outer side toward an inner side of the main body, and a needle for supplying ink to the main body is inserted into the first hole. The label in a film shape is attached to the main body. The second hole is provided at the label and overlaps the first hole in a plan view of the label. The second hole guides the needle to the first hole when the needle is inserted.

An ink bottle includes an ink jet ink composition and a storage section containing the ink jet ink composition. The ink bottle contains a substance having a thermal conductivity of 0.29 W/mK or less, and the ink jet ink composition contains at least one colorant having a coumarin backbone and also contains water.

A recording apparatus includes a tank including a chamber configured to store liquid to be supplied to a recording head that ejects the liquid and a filling port from which the liquid is injected into the chamber, and an injection auxiliary member configured to assist injecting of the liquid into the chamber from the filling port, the injection auxiliary member including a first and a second flow channels each defined by a first or a second upper end portion that opens toward outside of the tank and a first or a second lower end portion that opens toward inside of the tank, wherein the second flow channel has an expansion portion arranged in a middle portion between the second upper end portion and the second lower end portion and configured to form a step to expand a cross-sectional area.

A liquid-consuming apparatus includes: a tank including a liquid storage chamber which stores a liquid, an inlet formed in a surface of the tank, and an outlet through which the liquid from the liquid storage chamber flows; a cap which is movable between a first position and a second position; a cover which is movable relative to the tank between a closed position and an open position; and a holding member which is connected to the cap and which holds the cap at the second position. The cap at the second position or the holding member is configured to obstruct a movement of the cover from the open position to the closed position.
