For example, an anaerobic agent and a liquid mixed with the anaerobic agent are accommodated in separate accommodating chambers, and at least the anaerobic agent is accommodated in an accommodating chamber (accommodating body 45) having gas barrier properties. Thereby, the passage of oxygen or the like from the outside to the inside of the container 45 is prevented, and the entry of outside air into the container 45 is prevented, so that the anaerobic agent housed in the container 45 is altered and deteriorated. It can be stored for a long time until it is opened.

  Further, the two-chamber container 1 can easily mix the anaerobic agent and the liquid only by rotating the cap 40, and can take out the mixed liquid to the outside.

  When the two-chamber container 1 is used as, for example, an infusion bag, an anaerobic drug is accommodated in the container 45, and a liquid such as physiological saline is accommodated in the package 10 for use. An infusion solution is obtained by mixing the drug and the liquid. In this case, since it is necessary to take out the drip solution in the package with one needle of the catheter, a part of the cap can be easily formed by forming the rubber packing 14 as shown in FIG. It becomes possible to take out the drip solution to the outside.

  As shown in FIG. 9, the cap 40A includes, for example, a top plate 13a and a side body 13b that hangs down from the periphery of the top plate 13a. A cylindrical inner ring 15 that is concentric with the side body 13b is provided on the lower end surface of the top plate 13a so as to extend substantially vertically downward. The inner ring 15 always comes into contact with the inner wall surface of the tubular body 34 of the pouring tool base 33 in a state where the cap 40A is attached to the pouring tool base 33, and the content from the gap between the tubular body 34 and the inner ring 43. Prevents leakage to the outside. In addition, a through hole 13c is formed in a substantially central portion of the top plate 13a, and the surface of the top plate 13a is formed flat, and a rubber packing 14 is attached to the through hole 13c. ing.

  By using such a cap 40A, it is possible to take out the contents in the two-chamber container 1 to the outside by setting one needle of the catheter against both the packing 14 and the gas barrier material 49 of the cap 40A. Become. The other needle of the catheter is inserted into the patient.

  According to such a two-chamber container, since the drip liquid (liquid mixed with the anaerobic agent) does not flow out even if the drip or the like is performed without rotating the cap 40A, the operator can operate immediately. Can recognize mistakes. Accordingly, it is possible to prevent an erroneous operation due to forgetting to mix the liquid such as physiological saline and the anaerobic agent.
