が嵌合される。(Prior Art) Blood has conventionally been collected using a syringe, but recently, a vacuum blood collection method has been adopted. For this vacuum blood collection method, a blood test container having high airtightness is used. As shown in FIG. 4, the blood test container is composed of a tubular container body 50 having one end opened and the other end closed, and a plug body 60 for hermetically sealing an opening 51 of the container body 50. Then, the inside of the container main body 50 is brought into a predetermined depressurized state, and the plug body 60 is inserted into the opening 51
Are fitted.

量は，容器本体内の減圧度により規定される。As described above, the blood test container in which the opening 51 of the container body 50 is hermetically sealed by the stopper 60 is used during blood collection by the vacuum blood sampling method, and one end of the blood sampling needle is inserted into the blood vessel of the blood sampling subject. Then, the other end of the blood collection needle is inserted into the stopper 60, and blood is collected in the container body 50 by the pressure difference between the container body 50 of the blood test container and the blood vessel. The amount of blood flowing into the container body 50 is defined by the degree of pressure reduction in the container body.

定の減圧状態となった血液検査用容器が得られる。In order to bring the inside of the container body 50 into a predetermined depressurized state, the airtight box 70 shown in FIG. 4 is used, and it is carried out as follows. The container body 50 is held in the airtight box 70 in a substantially vertical shape, and the plug body 60 is placed on the open end of the container body 50. At this time, the plug body 60 is not airtightly fitted in the opening 51 of the container body 50. In such a state, the air in the airtight box 70 is exhausted through the opening / closing valve 71 to reduce the pressure in the airtight box 70. As a result, the inside of the container body 50 in the airtight box 70 is simultaneously depressurized, and the inside of the container body 50 is brought into a predetermined depressurized state. Then, when the predetermined depressurized state is reached, as shown in FIG. 5, after closing the on-off valve 71, the stopper 60 is pushed into the container body 50 by the pressing tool 72. As a result, the stopper 60 is airtightly fitted in the opening 51 of the container body 50, and a blood test container in which the inside of the container body 50 is in a predetermined reduced pressure state is obtained.
このような方法により血液検査用容器の容器本体50内を

述のように，容器本体50内を減圧する際には，栓体60は
該容器本体50の開口端上に載置されている。このため，
容器本体50内を減圧する際に栓体60が容器本体50内の空
気の排出を阻害するおそれがある。When decompressing the inside of the container body 50 of the blood test container by such a method, when decompressing the inside of the airtight box 70, the inside of the container body 50 must also be decompressed smoothly at the same time. If the inside of the container body 50 is not smoothly depressurized, the inside of the container body 50 may not be in a predetermined depressurized state. As described above, when decompressing the inside of the container body 50, the stopper 60 is placed on the open end of the container body 50. For this reason,
When depressurizing the inside of the container body 50, the plug 60 may hinder the discharge of air inside the container body 50.
このような問題を解決するために，第６図に示すよう

Grooves 61 having a predetermined length are formed in the axial direction. When decompressing the inside of the container body 50 using the plug body 60 having such a groove portion 61, the container body 50 is hermetically sealed with a part of the groove portion 61 fitted in the container body 50. Box 70
Retained within. When the airtight box 70 is depressurized, the air in the container body 50 is discharged through the groove 61 of the stopper 60, and the inside of the container body 50 is smoothly depressurized.

原因ともなる。(Problems to be Solved by the Invention) In this way, in the blood test container in a predetermined depressurized state, blood is collected in the container body 50. However, the groove 61
When the blood is collected, the plug body 60 having the gap formed therein may have a possibility that the blood may enter the groove 61 due to the capillary phenomenon. Groove
Blood that has entered the inside of 61 coagulates to form a blood clot, and such a blood clot is not removed from the groove 61 of the stopper 60 even when the container is subjected to a centrifugation operation to centrifuge the blood. It remains in the groove 61. The blood clot remaining in the groove portion 61 is formed in the groove portion when the container is vibrated or when the stopper 60 is opened while serum is obtained in the container body 50 by the centrifugal separation operation.
It may fall off from 61 and enter into serum. If the blood clot is mixed in the serum, the blood cell component is remixed in the serum, and if left as it is, various components such as electrolytes and enzymes are eluted from the blood cell component remixed in the serum. Since the serum contaminates it, it is necessary to perform the centrifugation operation again immediately. In addition, the mixing of blood cell components also causes hemolysis.
