## Abstract

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.

## Claims

### Claim 1

A package comprising:
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, said 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 said ink container and ambience, wherein said ink container has, at a side adjacent a side having said ink supply port, a first portion and a second portion which is projected outwardly of the ink container beyond the first portion, said first portion continuing with the side having the ink supply port, wherein said adjacent side takes a lower position; and
wherein said ink supply port and said air vent are opposed to each other in said package, and said ink supply port takes in said package a position at a level higher than the air vent, and when said adjacent side takes a lower position, it is at a position lower than said ink supply port.

### Claim 2 (depends on 1)

A package according to claim 1, wherein said ink supply port takes in said package a position at a higher level than a relatively high coloring material density region in the ink resulting from settling of the coloring material in said package.

### Claim 3 (depends on 1)

A package according to claim 1, wherein said pigment is carbon black.

### Claim 4 (depends on 3)

A package according to claim 3, wherein said carbon black is self-dispersion type carbon black.

### Claim 5 (depends on 1)

A package according to claim 1, wherein said pigment color is pigment.
