It is the object of the present invention to provide a sealed container which comprises a container comprising a thermoplastic resin and a stopper which is hardly slackening even when used in combination with the container, and a vacuum specimen-sampling container comprising the sealed container. The present invention is a sealed container, which comprises a container with an end being closed and the other end being open, comprising a thermoplastic resin, and a stopper being detachable and capable of sealing the open end of the container, the stopper having a head portion capable of being grasped, a leg portion A being extended downward from the head portion, being along an internal wall surface of the open end of the container, and being capable of exerting a fitting force to the internal wall surface, and a leg portion B being extended downward from the head portion, being along an external wall surface of the open end of the container, and being capable of exerting a fitting force to the external wall surface, and at least a portion of the leg portion B of the stopper contacting with the container and at least a portion of the container contacting with the leg portion A of the stopper having a deflection temperature under load of 60° C. or more under a load of 0.45 MPa or 0.46 MPa.

The invention claimed is: 1. A sealed container, which comprises a container with an end being closed and the other end being open, comprising a thermoplastic resin, and a stopper being detachable and capable of sealing the open end of the container, the stopper having a head portion capable of being grasped, a leg portion A extending downward from the head portion, extending along an internal wall surface of the open end of the container, and being capable of exerting a fitting force to the internal wall surface, and a leg portion B being extending downward from the head portion, the leg portion B having an external contact surface extending downward from the head portion, and the external contact surface contacts throughout an external wall surface of the open end of the container, and the external contact surface being capable of exerting a fitting force to the external wall surface, and the external contact surface having a deflection temperature, under a load of 0.45 MPa or 0.46 MPa, which is higher than a deflection temperature, under a load of 0.45 MPa or 0.46 MPa, of at least a portion of the container, which contacts the leg portion A of the stopper; wherein the leg portion A of the stopper is made of a thermoplastic elastomer or a thermosetting elastomer or the leg portion A has a surface layer comprising thermoplastic elastomer or a thermosetting elastomer at least at a portion contacting the internal wall surface of the container; and, wherein a position of the fitting force exerted between the leg portion A of the stopper and the internal wall surface of the container being greatest and a position of the fitting force exerted between the external contact surface of the leg portion B of the stopper and the external wall surface of the container being greatest are located at different positions in the longitudinal direction of the container. 2. A vacuum specimen-sampling container, comprising the sealed container according to claim 1, the inside thereof being in a reduced atmospheric pressure state. 3. The sealed container according to claim 1, wherein the deflection temperature, under a load of 0.45 MPa or 0.46 MPa, of the at least the portion of the leg portion B of the stopper, which contacts the container, is 60° C. or more, and the deflection temperature, under a load of 0.45 MPa or 0.46 MPa, of the at least the portion of the container, which contacts the leg portion A of the stopper, is 60° C. or more. 4. The sealed container according to claim 1, wherein the stopper has a needle pipe insertable portion comprising a thermoplastic elastomer or a thermosetting elastomer. 5. A vacuum specimen-sampling container, comprising the sealed container according to claim 4, the inside thereof being in a reduced atmospheric pressure state. 6. The sealed container according to claim 1, wherein a distance of the leg portion B of the stopper contacting with the external wll surface of the container is shorter than a distance of the leg portion A of the stopper contacting with the internal wall surface of the container in the longitudinal direction of the container. 7. The sealed container according to claim 6, wherein a position of the fitting force exerted between the leg portion A of the stopper and the internal wall surface of the container being greatest and a position of the fitting force exerted between the leg portion B of the stopper and the external wall surface of the container being greatest are located at different positions in the longitudinal direction of the container. 8. The sealed container according to claim 6, wherein the leg portion A of the stopper has a surface layer comprising a thermoplastic elastomer or a thermosetting elastomer at least at a portion contacting with the internal wall surface of the container. 9. The sealed container according to claim 6, wherein the stopper has a needle pipe insertable portion comprising a thermoplastic elastomer or a thermosetting elastomer. 10. A vacuum specimen-sampling container, comprising the sealed container according to claim 6, the inside thereof being in a reduced atmospheric pressure state. 11. The sealed container according to claim 1, wherein the leg portion A of the stopper has a surface layer comprising a thermoplastic elastomer or a thermosetting elastomer at least at a portion contacting with the internal wall surface of the container. 12. The sealed container according to claim 11, wherein the stopper has a needle pipe insertable portion comprising a thermoplastic elastomer or a thermosetting elastomer. 13. A vacuum specimen-sampling container, comprising the sealed container according to claim 11, the inside thereof being in a reduced atmospheric pressure state.
