Description of the Related Art Conventionally, at the mouth of a medical container, the solution in the container is discharged by opening the sealed portion of the mouth and connecting a needle. . The construction and opening of the sealed portion are performed by the following method. (1) Tamper seal type (see FIG. 4) A tamper seal film, sheet 11 or the like is heat-sealed to the top surface 12 of the sealing portion of the mouth portion so as to be opened,
For opening, the grip is pulled up until the opening is completed. (2) Twist open type (see FIG. 5) The upper end of the mouth portion provided with the fragile portion 14 is sealed.
To open the bag, twist the upper portion 13 of the mouth to tear off the fragile portion 14. (3) Protector type (see FIG. 6) The mouth is covered with a protector 17 provided with a fragile portion 16 and sealed. The opening is performed by the grip portion 1 connected to the fragile portion 16.

でコストアップにつながっていた。The problems (1) to (3) described above have the following problems. (1) In the tamper seal type sealing structure, it is difficult to adjust the welding strength of the mouth portion, the sealing sheet and the film 11,
Care must be taken when selecting the material of the sheet and film, especially
In the case of vinyl chloride resin, if the sheet material and welding conditions are wrong, the opening may not be possible. (2) Twist open type sealing structure is used for the fragile part 1.
When breaking No. 4, there was a possibility that it would be difficult to break unless it was strongly twisted, and at the time of breaking, scraps of the resin cut out might enter the inner circumference of the mouth. (3) The protector type sealing structure requires a step of manufacturing the protector 17 (sealing the outer circumference and the fracture surface), which leads to an increase in cost.

より液密に密封した医療用容器である。The present invention has been studied in order to solve the above-mentioned problems, and includes a mouth main body 2 and a cap 6.
A mouth part of a medical container constructed by sealing with a mouth body 2, in which a fitting groove 3 is coaxially formed in an upper part, and a cap 6 is provided with a cylindrical fitting leg 4 on a lower surface thereof. Is
A fragile portion 5 is formed in the middle of the fitting leg 4,
The mouth portion main body 2 and the cap 3 are fitted by fitting into the fitting groove 3 and the fitting leg 4 and the fitting portion 10 of the fitting groove 3 are mutually blocked by high-pressure steam sterilization treatment. It is a tightly sealed medical container.

The fitting part 10 is sealed by blocking. When the medical container is used, when the grip portion 7 of the cap 6 is pulled up, the force concentrates on the fragile portion 5 provided on the fitting leg 4 of the cap 6. Since the lower part of the fitting leg 4 blocks the fitting groove 3,
It does not come off, the fragile portion 5 breaks, the cap 6 comes off the mouth body 2, and the opening is completed.

(FIG. 1 is a cross-sectional view before fitting the cap 6 and the mouth main body 2, and FIG. 2 is a cross-sectional view showing a state in which the cap 6 is fitted in the mouth main body 2). Medical container 9 and mouth 1
Is composed of polyvinyl chloride resin. The mouth part 1 has a mouth part body 2 having a fitting groove 3 coaxially formed on an upper part thereof, and a fitting leg 4 projecting cylindrically from a lower surface, and a fragile part 5 is formed in the middle of the fitting leg 4. It is composed of a colored cap 6. The cap 6 and the mouth main body 2 are fitted by fitting the fitting leg 4 into the fitting groove 3, and by performing high-pressure steam sterilization treatment in this state, the fitting leg 4 and the fitting groove 3 are fitted together. The parts 10 block each other, and these fitting parts 10 can be liquid-tightly sealed.

On the other hand, since the fitting leg lower portion 4a remains in the fitting groove 3 after being broken as shown in FIG. 3, the mouth body 2 cannot be sealed with the cap 6 again. After opening the mouth main body 2,
By puncturing the membrane 8 with a synthetic resin bottle needle (not shown) such as a blood transfusion set, the internal solution in the medical container 9 can be discharged.

Further, although the protrusion 3a that fits with the outer periphery of the fragile portion 5 is provided on the outer periphery of the fitting groove 3, this protrusion may or may not be provided. Although the fitting leg 4 and the fitting groove 3 shown in FIGS. 1 and 2 are in close contact with both the inner circumference and the outer circumference, they may be fitted with the inner circumference or the outer circumference being in close contact. . Further, although a rubber stopper is not used for the mouth portion 1, it is possible to insert a rubber stopper between the membrane 8 and the cap 6 for sealing.
