PROBLEM TO BE SOLVED: To effectively prevent the evaporation of ink by arranging a vent hole and an air communication groove in a first area, arranging an air communication hole in a second area and adding film members inseparably on the first area and separably on the second area. SOLUTION: An ink container 100 has a container part 10 and a lid part 20 linked integrally. The lid part 20 has a first area 20A and a second area 20B arranged adjacent to each other with a step. A vent hole 21 for connecting each ink substance 12 to the air is formed penetrating the first area 20A, and a serpentine air communication groove 22 connected to the vent hole 21 is recessed to an upper face of the first area. An air communication hole 23 opened to an upper face is formed in the second area 20B. A first film member 31 for sealing the vent hole 21 and covering the air communication hole 22 is inseparably attached to the first area 20A, and a second film member 32 for sealing the air communication hole 23 is separably attached to the second area 20B so that the air communication hole 23 can be opened to the air. |
