In the medical container of No. 269486, the spout is welded to the side portion of the sheet of the container, and the sheet portion constituting the main body of the medical container serves as a diaphragm that separates the drug solution and the spout. There are two types of spouts, one with a rubber stopper and the other without a rubber stopper. For the type with rubber stopper, the rubber stopper keeps the liquid tightness when the needle is pierced.For the type without rubber stopper, the inner circumference of the spout body and the fitting part of the bottle needle should fit. Keeps the liquid tightness.

とが可能である。EXAMPLES As shown in FIG. 1, a spout 1 is constructed by integrally molding a cylindrical spout body 2 and a flange 4 at the bottom thereof, and a bottle needle is provided on the inner circumference of the spout body 2. A convex portion 3 for holding is provided. A sealing member such as a tamper seal sheet 5 is attached to the top surface of the spout body 2. The flange 4 is a sheet portion 6 that constitutes a medical container.
Is welded. For the constituent member of the spout 1, for example, a soft polyvinyl chloride resin is used for both the seat portion 6,
It is also possible to use a flexible elastomer such as linear low-density polyethylene or syndiotactic polypropylene.

To insert the synthetic resin bottle needle 7 into the spout 1 and to communicate with the drug solution in the medical container 13, remove the tamper seal sheet 5 and remove the synthetic resin at the tip of the upper tube 8 of the infusion set (not shown). The bottle making needle 7 is attached to the spout main body 2
, The tip 9 of the bottle needle 7 is passed through the sheet portion 6, and the bottle needle 7 is pushed until the fitting portion 11 of the bottle needle 7 fits inside the spout body 2.

Actually, the bottle needle does not stay in this state, but is put in the position shown in FIG. 4 described above. Instantly, when the position of FIG. 3 and FIG. 5 is reached, the pressure of the sheet portion acting on the opening 12 of the sheet 6 in the direction of the bottle needle 7 is weak. Although it may ooze out, in FIG. 3, since there is a convex portion 3 inside the spout main body 2, the convex portion 3 holds the outer periphery of the bottle needle 7, so that liquid tightness is maintained. On the other hand, in FIG. 5, since the convex portion 3 is not provided, there is a risk that the chemical liquid oozing from the opening 12 oozes into the spout 21.
