ある。 In order to remove the lid of the sealed container while maintaining airtightness between the two when the sealed container is joined to the glove box, the glove box is provided with a sealed container opening/closing device. To explain the outline of this device, it includes a flange fixed to a through hole for fitting a sealed container formed in the base plate of the glove box, a cover that closes the hole of the flange, and a cover fixed to the outer peripheral surface of the cover. It has an upper sealing material that is brought into pressure contact with the inner circumferential surface of the hole in the flange, and a cover moving device that moves the cover away from the flange. However, since the upper sealing material is worn out during repeated use, it is necessary to replace the upper sealing material at an appropriate time. However, if the cover is simply separated from the flange and the upper sealing material is replaced, harmful substances (such as radiation) inside the glove box will leak out through the holes in the flange. Conventionally, a method has been proposed in which the hole in the flange is closed, the cover is moved away from the flange, and the upper sealing material is replaced, but this method still requires a large device and is time-consuming to replace. The bottom surface of the cover becomes contaminated, especially when replacing the sealing material, and if this continues, when the cover is inserted into the hole in the flange, the contaminated bottom surface will be exposed to the outside. There is a problem of exposure.

ので、その下面が汚染されるおそれもない。 Therefore, the present invention provides a method for replacing the sealing material of a sealed container opening/closing device that solves such problems. a flange fixed to the flange, a cover for closing the hole in the flange, an upper sealing material fixed to the outer peripheral surface of the cover and pressed against the inner peripheral surface of the hole in the flange, and separating the cover from the flange. a sealed container opening/closing device having a cover moving device, a fitting body that fits into a through hole for fitting the sealed container to close the through hole, and a lower sealing material that is fixed to the fitting body and press-contacted to the flange. and a lid that is attached to the fitting body and integrally connected to the cover via an upper sealing material, and the fitting body of the replacement jig is fitted into the through hole for fitting the sealed container. At the same time, the lower sealing material is pressed against the flange to close the through hole, and the lid is integrally connected to the cover via the upper sealing material, and then the cover is separated from the flange together with the lid and the upper sealing material by a cover moving device. Next, a new lid and a cover with an upper sealing material prepared in advance are fitted into the hole of the flange, the new lid is removed from the cover and attached to the fitted body, and the fitted body is separated from the through hole. . According to this method, the apparatus is small, and especially when a sealed container is used as a replacement jig, it is only necessary to prepare a new lid and a cover with an upper sealing material, which is extremely economical. Moreover, the replacement procedure is almost the same as the procedure for fitting and removing a sealed container into a glove box, so that replacement does not require much effort. Furthermore, since the lower surface of the cover is completely covered by the upper sealing material and the lid, there is no risk of contamination of the lower surface.

完全に密着する。 The operation of the above configuration will be explained. Figure 2 shows support stand 3
The figure shows the sealed container 4 being lifted up through the . At this time, the disc 20 is stopped at a preset position below the cover 17 by the operating body 24 acting on the limit switch 25.
At this time, the cover 17 is pressed to the flange 16 via the upper sealing material 18 by the biasing force of the spring 22. In this state, the sealed container 4 is further raised,
The lower sealing material 9 is pressed against the lower surface of the flange 16. At this time, the glove box side protrusion 21 passes through the space between the lid side inner protrusion pieces 14, and the disc 20 is thus positioned within the recess 32, resulting in the state shown in FIG. At this time, the meshing of each part is as shown in FIG. 6, and the glove box side meshing structure 30 is in a non-meshing state as described above.
Further, the container side meshing structure 10 has a container side inner protrusion piece 1.
1 is in an engaged state with the lid locking tongue piece 13 inserted below. Further, the meshing structure between the container and the flange is in a non-meshing state. That is, the lid 8 is attached to the sealed container 4 side. Here, even if the lower surface of the flange 6 and the upper surface of the sealed container 4 are not parallel to each other, the sealed container 4 can be
By applying it to the flange 16 through the flange 16, the flange 16 swings about the spherical bush 52 as a fulcrum, and the two automatically become parallel to each other and are in perfect contact with each other.

片３１の上に位置することになる。 Next, the sealed container 4 is rotated in the direction of arrow A via the support stand 3. Then, as shown in FIG. 7, by rotating by a predetermined angle θ 1 , the container-side outer projection piece 36 is positioned above the container-locking tongue piece 40, and the lid 8 is also rotated together and the lid-side inner projection piece 36 is positioned above the container locking tongue piece 40. The piece 14 will be located above the glove box side tongue piece 31.

Then, as shown in FIG. 8, by rotating by a predetermined angle θ 2 , the container side outer protruding piece 36 moves over the container locking tongue piece 40 while remaining in the engaged state, but the lid 8 is moved by the second pusher. Since the surface 14A is in contact with the second pushed surface 21A, it does not rotate. Therefore, the container-side inner projecting piece 11 comes off from the top of the lid locking tongue piece 13.

and the upper sealing material 18 are integrated into the flange 1.
6 and take it out of the glove box 7 through the entrance 62. In addition, a new support block 53A prepared in advance outside the glove box 7,
Insert the cover 17A, lid 8A, upper sealing material 18A, etc. into the glove box 7 through the entrance 62,
Fit it into the hole of flange 16. Next, after lowering the support girder 47 in the reverse procedure to the above, bolts 60 are fixed to the new support block 53A, and a new lid 8 is attached.
If A is attached to the sealed container 4 and the sealed container 4 is separated from the flange 16, a new upper sealing material 18 is installed.
A is brought into pressure contact with the inner peripheral surface of the hole of the flange 16, and the replacement of the upper sealing material 18A is completed.
上記構成では、取換治具として密封容器を用い
たが、これに代えて第９図に示すごとく、嵌合体
６５と下方シール材９と蓋８と押えリング３５と
からなる専用の取換治具３６を用いてもよい。 In the above configuration, a sealed container is used as the replacement jig, but instead of this, as shown in FIG. A tool 36 may also be used.

蓋とで完全に履われているので、その下面が汚染
されるおそれもない。 As described above, according to the present invention, the apparatus is compact, and especially when a sealed container is used as a replacement jig, it is only necessary to prepare a new lid and a cover with an upper sealing material, which is extremely economical. Moreover, the replacement procedure is almost the same as the procedure for fitting and removing a sealed container into a glove box, so that replacement does not require much effort. Furthermore, since the lower surface of the cover is completely covered by the upper sealing material and the lid, there is no risk of contamination of the lower surface.
