Liquid storage container and liquid ejection apparatus

A liquid ejection apparatus, comprising:

• a liquid ejection head that ejects liquid;
• a liquid storage container constructed to store a liquid supplied to the liquid ejection head, including a storage chamber for storing a liquid and a supply port constructed to supply a liquid to the storage chamber from an outside;
• and
• a cover member that mounts detachably on the supply port, wherein
• the cover member includes a main body part lying outside of the storage chamber and the supply port in a state mounted on the supply port;
• the main body part includes a cover part covering an opening surface of the supply port in the mounted state of the cover member, a support part constructed to connect the cover part with another member with the cover member removed from the supply port, and a convex part protruding from the cover part;
• and
• the convex part is arranged only on one side of the cover part and the support part is arranged on the other side of the cover part relative to a straight line intersecting orthogonally with a straight line passing a centroid of the cover part and connecting the centroid and the support part, seen from a direction intersecting orthogonally with the opening surface in the mounted state of the cover member.
