A container for a two-component medicament, configured in such a manner that, when a cap is turned in the direction of opening the container body to administer eye drops, etc., the cap can be removed without causing a nozzle cap and the container body to become loose relative to each other. A nozzle cap (2) configured in such a manner that a small-diameter annular section (14) on which upper-stage outer ratchet teeth (16) are formed and a large-diameter annular section (15) on which lower-stage outer ratchet teeth (17) are formed are provided to the outer surface of a nozzle section (12) of the container body (1) and that a barrel section (22) and a ring section (23) for sealing are connected together in a breakable manner. Upper-stage inner ratchet teeth (28) and lower-stage inner ratchet teeth (29) are provided to the inner surfaces of the barrel section (22) and the ring section (23) for sealing. When the container body is in a closed state before use, only the inner and outer ratchet teeth (17, 29) at the lower stages are engaged with each other to prevent the nozzle cap from rotating in the direction of opening the container body, and in a state in which the container body is closed by the nozzle cap (2) which does not have the ring section (23) for sealing, the inner and outer ratchet teeth (16, 28) at the upper stages are engaged with each other to prevent the nozzle cap from rotating in the direction of opening the container body. |
