Claims

[Scope of utility model registration request]

The total length is set to a length that allows the rear end notch to protrude from the rear end opening of the outer cylinder when a notch is provided at the rear end and the ink is installed inside the outer cylinder, and a circumferential groove and a vertical groove are formed to store ink. A tail plug is formed by connecting the circumferential groove and the vertical groove to the rear end to form an air flow passage, and the tail plug is press-fitted into the inner hole of the rear end notch that protrudes from the rear end opening of the outer cylinder. A refill for writing instruments such as water-based ballpoint pens that is characterized by its sticking properties.
