Claims

[Scope of utility model registration request]

A transport mechanism including a transport means for transporting a test tube containing a sample along a transport path and a stop means for temporarily stopping the test tube at a first position and a second position on the transport path, and a stop means for the transport mechanism. A film tensioning mechanism that horizontally pulls out and stretches a sealing film above the opening of a test tube stopped at a first position; a film contact mechanism that cuts out a film piece, lowers the film piece while holding its periphery, and brings the central part of the film piece into contact with the opening of the test tube; and the film contact mechanism brings the central part into contact with the opening of the test tube. A sealing film is applied to the opening of the test tube by narrowing it down with a cylindrical body that fits into the test tube so that the peripheral part of the film piece that is in contact with the test tube is aligned with the outer peripheral surface of the test tube. a film covering mechanism for covering the piece;
After coating the sealing film piece by the film covering mechanism, film welding involves welding the peripheral portion of the film piece to the outer peripheral surface of the test tube that is transported by the transport means and stopped at the second position by the stop means. A test tube opening sealing device characterized by comprising a mechanism.
