DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a view showing the overall sectional structure of an embodiment of a medical container according to the present invention, FIG. 2 is a sectional view of an injection valve, and FIG. 3 is a sectional view of a safety valve. First, referring to FIG.
A general view of the medical container 100 according to the present invention will be clarified, and then the structures of the injection valve 50 and the safety valve 70 will be clarified. The medical container 100 includes a container body 10 made of stainless steel having an opening 11 in an upper part thereof, and a lid 20 also made of stainless steel attached to the upper part of the container body 10 so as to cover the opening 11. The container body 10 is of a cylindrical type, and has a flange portion 12 extending over the entire circumference at an outer peripheral portion of an upper portion near the opening 11, and a portion further closer to the opening 11 than the flange portion 12 is a male screw portion 13. . On the other hand, the lid 20 is cup-shaped, and includes a disc-shaped upper portion 21 and a cylindrical side portion 22. Lid 20
A female thread portion 23 suitable for the male thread portion 13 is provided on the inner periphery of the side portion 22 of the. The lid 20 has a female screw portion 23 screwed to the male screw portion 13 on the container body 10 side,
It is attached to the container body 10 side. Due to the screw connection, the lid 20 can be repeatedly attached and detached for many times. Here, since the ring-shaped sealing material 30 made of silicon rubber is disposed on the flange portion 12, the lid 20 can sandwich the sealing material 30 and seal the space with the container body 10. Therefore, the space 15 inside the container 100 partitioned by the lid 20 and the container body 10 is completely shielded from the outside.

The lid 20 has two valves incorporated therein. One is an injection valve 50 and the other is a safety valve 70.
Both valves 50, 70 are structurally similar and are composed of a cylindrical valve housing 51, 71 and valve mechanisms 52, 72 arranged inside the valve housing 51, 71. Each of the valve housings 51, 71 has a mounting screw portion 51 on the outer peripheral portion.
a, 71a are formed, and each valve 50, 70 is provided with a lid 2
It is attached by screwing it into the screw holes 215 and 217 penetrating the upper portion 21 of the No. 0 screwdriver. Again, because of the screw connection, each valve 50,
The 70 can be easily replaced with a new one. The injection valve 50 normally shuts off the inside and outside of the container 100, but when the pressure on the outside of the container 100 increases, the injection valve 50 moves from the outside of the container 100 to the space 15 inside the container according to the pressure difference between the inside and the outside. It is a valve that allows the flow of fluid toward it. As shown in FIG. 2, the valve mechanism 52 of the injection valve 50 includes a small piston 5 that is movable along the inner circumference of a cylindrical valve housing 51.
3, a mandrel 54 extending to the center of the small piston 53, a mandrel supporting member 55 that supports the mandrel 54, and a valve spring 56 that urges the small piston 53 to move away from the mandrel supporting member 55 while being supported by the mandrel 54. Including and Small piston 53
Is normally located above the valve housing 51 by the urging force of the valve spring 56, and blocks the front and rear thereof, that is, the communication between the inside and outside of the lid 20. However, when the pressure outside the container 100 rises during steam sterilization, the urging force of the valve spring 56 is overcome, and the small piston 53 moves to the groove passage 57 portion inside the valve housing 51. Therefore, in that case, the inside and outside of the container 100 communicate with each other through the groove passage 57. Further, the safety valve 70 normally shuts off the inside and outside of the container 100, but when the pressure outside the container 100 becomes low, the safety valve 70 responds to the pressure difference inside and outside the container 100.
It is a valve that releases the internal pressure to the outside of the container 100. The valve mechanism 71 of the safety valve 70 includes a small piston 73, a mandrel 74, a mandrel supporting member 75, and a valve spring 76, similar to that of the injection valve 50. The valve mechanism 71 of the safety valve 70 is configured such that the entire valve mechanism is attached to the lid 20 upside down as compared with the valve mechanism 51 of the injection valve 50. Therefore, in normal times,
The small piston 73 is located below the valve housing 71,
The inside and outside of the lid 20 are shut off. However, when the pressure outside the container 100 becomes low (vacuum) during evacuation after the sterilization process and the pressure difference between the inside and the outside exceeds a predetermined value, the small piston 73 causes the groove passage 77 in the upper inner circumference of the valve housing 71 to move. It moves to a part and communicates the inside and outside of the container 100.

The injection valve 50 introduces high-pressure steam into the space 15 inside the container 100 during the sterilization process, and
Helps to effectively sterilize the gauze, cotton and other medical items it contains. On the other hand, the safety valve 70 prevents the pressure difference between the inside and the outside of the container 100 from becoming larger than a predetermined value at the time of exhaust (and also at the time of sterilization processing), and reliably solves the problem such as breakage of the container 100. Moreover, since both valves 50 and 70 are closed when the sterilization is completed, the inside of the container 100 is completely sealed. Therefore, the medical supplies inside are in good hygiene for a long time.

It is also possible to extend one end on the outside of the safety valve 70 as shown by the chain line in FIG. 3 and use that portion as the manual operator 60. In some cases, the container 100
The pressure difference remains inside and outside the lid, and when using medical supplies, the lid 20
However, in such a case, the safety valve 70 can be forcibly opened by pulling the manual operator 60. Then, there is no pressure difference between the inside and the outside of the container 100, and the lid 20 can be easily opened. Of course, a valve provided with such a manual operator 60 may be provided separately from the safety valve 70, but if it is added to the safety valve 70,
The whole structure can be made that simple.

[0009]

According to the present invention, the inside and the outside of the medical container 100 are hermetically sealed, and the lid 20 is provided with the injection valve 50 and the safety valve 70. Therefore, it is possible to effectively cope with a process such as steam sterilization. It is possible to provide a medical product with high hygiene.
