ABSTRACT:
A airtight cap structure is capable of coming into close contact with a tip to be used and securing airtightness, even if the tip might be inserted in the cap with having a relative angle or offset between the cap and the tip. A cap comprises an outer cap and an inner cap arranged in the outer cap. The inner cap is mounted to the outer cap so that the inner cap can incline relative to the central axial line of the cap, and the cap comes into close contact with the tip or its periphery when the cap covers the tip.
