Double-sealed design, Leak-less even without O-ring

1st sealing point where the protruding part is located inside of the cap makes
the clearance between the cap and the body seal.
By fully tightening the cap, 2nd sealing point makes both upper and main body seal
completely seal, resulting in preventing test sample leakage and evaporation.
