PROBLEM TO BE SOLVED: To provide a body fluid container assembly (evacuated blood collecting tube) which can prevent the scattering of a body fluid sample when a plug body is taken out from the assembly without requiring the diameter increase of the assembly and is highly safety to inspection workers, etc. SOLUTION: This evacuated blood collecting tube 1 is provided with a container having an opened base-side end 21 and a closed front end 22 and the plug body 3 which airtightly seals the opened end 21 of the container 2. The plug body 3 is constituted of a putting section 31 which is put in the opened end 21 of the container 2 and a large-diameter section 32 which is integrally formed with the base-side end section of the putting section 31 and has a larger diameter than the section 31 has. The base-side end section of the tube 1 is fitted with a flexible film 4 which covers the outer periphery of the plug body 3. The film 4 not only covers the outer peripheral surface of the large-diameter section 32 of the plug body 3, but also the outer peripheral surface of the base-side end section of the container 2. When the plug body 3 is taken out from the container 2, the film 4 is joined to the large-diameter section 32 of the plug body 3 and separated from the container 2 together with the plug body 3. The film 4 is provided with a plurality of openings 42 formed as slip preventing means.
