Abstract: A liquid storage container includes: a discharge port member including a discharge port through which liquid stored in a storage portion is discharged; a cover portion configured to be attachable to the discharge port member and to be capable of opening and closing the discharge port; and a sealing portion formed of a contact portion between the cover portion and the discharge port member. The cover portion includes a groove structure between an outer periphery of the cover portion and the sealing portion.

Abstract: A liquid container includes a liquid containing portion configured to contain liquid, an outlet portion including an outlet port configured to discharge therethrough the liquid contained in the liquid containing portion, and a protection portion configured to cover the outlet port of the outlet portion. The protection portion has a first opening portion located above the outlet port. Where a diameter of the opening portion is defined as D, and a distance between the outlet port of the outlet portion and the opening portion in a vertical direction is defined as L, inequality (1) is satisfied.

Abstract: A cover member configured to be removable from a liquid container. The cover member includes a resin having a haze value of 14% or more and 96% or less. A thickness of a top surface of the cover member is 3.0 mm or less. A maximum height roughness Rz of the top surface of the cover member is 50 ?m or less. When a back surface of the top surface of the cover member is defined as a first surface and a surface of the protection portion facing the first surface is defined as a second surface, an L? value of the second surface in Commission Internationale de l'Eclairage (CIE) L?a*b*color space is 5 or more and 35 or less. A shortest distance between the first surface and the second surface is 0.4 mm or more and 2.0 mm or less.

Abstract: A member mountable to a mounting portion provided with an ink receiving tube and a plurality of electrical connecting portions, the member includes a first portion including an outwardly facing surface and provided with an inserting portion into which the ink receiving tube is capable of being inserted; a second portion opposite from the first portion; and a third portion connecting the first portion and the second portion with each other and provided with a plurality of pad electrodes electrically connectable with the electrical connecting portions. The member is mountable to the mounting portion by being inserted into the mounting portion in an inserting direction with the first portion at a leading side. The pad electrodes are electrically connectable with the electrical connecting portions by being moved in a direction different from the inserting direction.

Abstract: A liquid ejection apparatus includes: an ejection head; a liquid reservoir; and a pressure control mechanism controlling a pressure of liquid supplied from the liquid reservoir and supplying the ejection head with liquid, the pressure control mechanism including a pressure chamber with the ejection head, a lever member connected to the valve element at a load and connectable to a pressure receiving member for a pressure of the pressure chamber at an effort, and a biasing mechanism biasing the valve element at the load of the lever member, the pressure control mechanism controlling a pressure of the pressure chamber. In the pressure control mechanism, a lever ratio, which is a ratio of a distance between the effort and fulcrum of the lever member to a distance between the load and fulcrum of the lever member, is greater than 1 and less than 5.

Abstract: A magnesium clad material 100 includes, when a cross-section thereof cut in a thickness direction thereof is observed, a Mg layer (11), a first Al layer (12) made of pure Al or an Al alloy, and a first joint (13) made of pure Cu or a Cu alloy and arranged between the Mg layer and the first Al layer, and the magnesium clad material has a 0.2% proof stress of 150 MPa or more as measured in a tensile test under a room temperature atmosphere.
