The invention relates to an instillation container comprising a container ma in body (A) made of thermoplastic material, and a cap (B) threadedly fittable o n the container main body, wherein a liquid instillation sleeve (6) formed at the front end of the container main body is formed with a bottom-closed conical recess (6b) whose inner diameter increases toward its front end, a liquid instillation hole (6c) is formable or formed in the bottom of the recess, and the cap (B) is provided with a first raised sealing portion (15) for sealing the recess (6b) of the container main body (A) when the cap is mounted. The problem of the invention is to provide an instillation containe r that has improved sealability between the main body container and the cap in their threadedly fitted state and that can properly set the amount of single instillation at the time of instillation. To solve this problem, according t o the invention, the outer periphery of the liquid instillation sleeve (6) is provided with a level-difference portion (8a) whose outer diameter sharply decreases toward the front end (T) of the container main body (A), and a fro nt end projection (8b) is formed that is positioned forwardly of the level- difference portion (8a) and whose outer diameter substantially does not decrease or change toward the front end, while the cap (B) is provided with a second raised sealing portion (16) that intimately contacts the front end projection (8b) and level-difference portion (8a) when the cap is mounted.</ SDOAB>
