に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to contain, safely protect and transport articles such as semiconductor wafers, aluminum disks for magnetic disks, quartz glass for photomasks, etc. The present invention relates to a sealed container and a method for opening the same.

Description of the Related Art Conventionally, the hermetically sealed container for the above-mentioned use has a poor performance of maintaining a hermetically sealed condition when the atmospheric pressure of the environment is changed due to transportation of an aircraft or the like. Although the container could be opened without any need to release the seal, it had a drawback that dust in the atmosphere could easily get into the container during transportation and cause contamination of the items to be stored.

に蓋を開けることのできる密封容器を提供するにある。However, with the recent improvement in the container sealing structure, it may take several days for the pressure difference generated during transportation of the aircraft to be alleviated. Further, when the pressure inside the container is closed under reduced pressure, the lid (and / or the container) is pressed against the container (and / or the lid) by the atmospheric pressure, making it difficult to open. Therefore, an object of the present invention is to provide a hermetically sealed container which can be quickly opened when necessary even when the inside of the container is sealed under a reduced pressure.

It is characterized by the provision of a hole or notch that reaches up to, and by pressing this gasket into the container with a pressing jig through the hole or notch, or by passing a communication pipe through the gasket. It concerns the method of opening.

Since it is possible to inject the purified air of 3 to cancel the pressure difference between the inside and outside of the container, the suction state of the lid is canceled and the container can be easily opened and closed. Further, when the sealed air is released, if the stored air may be contaminated by the outside air flowing into the container, it can be prevented by attaching a dust filter to the outside air side of the communication pipe.

Reference numerals 3 and 4 are the peripheral portions of the respective openings. First shown in FIG.
In the embodiment, the lid 1 and the container 2 are in contact with each other, and the opening peripheral portions 3 and 4 each have a double wall structure, and between them, an h-shaped cross section, a T-shaped cross section, an X-shaped cross section, a W-shaped cross section, and the like. By interposing the gasket 5 of arbitrary shape in close contact with the surrounding wall surface and bringing the outer walls 6 and 7 into contact with each other, the lid 1 and the container 2 are fitted and sealed. Reference numeral 8 is a hole provided through the fitting / sealing portion. Reference numeral 9 is a communication tube such as an injection needle for releasing the state when the lid becomes difficult to open and close due to a pressure difference between the inside and outside of the sealed container, which is inserted through the hole 8 and pierced into the gasket 5. , By passing or injecting air into the vessel. At this time, if there is a risk that the stored items will be contaminated by the inflow of outside air, it can be prevented by attaching a dust filter 10 to the inlet of the communication pipe 9. Also, by pressing the inside of the container to a pressurized state with a press-fitting device such as a syringe, the lid 1
The fitting of the container 2 and the container 2 can be released by (air) pressure.

The structure, the shape and arrangement of the gasket 5, the method of fitting / sealing the lid 1 and the container 2 and the like are the same as those in the first embodiment, but the fitting / sealing portion is cut on the opening peripheral edge 3 side. The difference is that the notch 11 is provided so as to penetrate therethrough. Reference numeral 12 is a rod-shaped pressing jig which is inserted through the notch 11 and pushes the gasket 5 into the container to form a gap at the seal point to release the seal. The rod-shaped pressing jig 12 may be applied to the first embodiment, and the dustproof filter 10 described above may be used.
The communication tube 9 and the press-fitting device provided with may be applied to the second embodiment.

ることができる。How the holes 8 and the notches 11 are provided depends on the structure of the opening peripheral portions 3 and 4 and the cross-sectional shape of the gasket. For example, when the opening peripheral portions 3 and 4 and the gasket 15 have a simple structure as in the third embodiment shown in FIG. 4 (a), there is only one hole 8 on the outer wall 6 of the opening peripheral portion 3. The seal can be released as shown in FIG. However, when the grooves of the opening peripheral edge portions 3 and 4 are deep as in the fourth and fifth embodiments shown in FIGS. 4B and 4C, the holes 8 are formed in the side walls of the opening peripheral edge portions 3 and 4, respectively. Or cutout 11 is required. These holes 8 or notches 11
The position may be attached anywhere on the side wall around the gasket 15, and if the size is larger than the size in which the communication pipe 9 and the pressing jig 12 are inserted, the sealing can be released. But hole 8
Alternatively, if the notch 11 is provided at the seal point or the gasket 15 is of a size that is deformed, it is natural that a problem occurs in the function. Incidentally, when it is disliked that the gasket 15 is always exposed for some purposes, a plug 13 can be attached to the hole 8 as shown in FIG. 4 (e). In the sixth embodiment shown in FIG. 5, an O-ring having a circular cross section is used as the gasket 25. In this case, a notch 21 extending over the peripheral portions 3 and 4 of both openings is provided, and as shown in FIG.
The seal can be released by pressing the gasket 25 into the container with 12.

It is preferable to use an elastomer of ° in terms of sealing property. Examples of such an elastomer include silicone rubber, styrene-based, olefin-based, and polyester-based thermoplastic elastomers. If silicone rubber is used for the gasket, the volatile components will contaminate the contents, so the total amount of low molecular weight polysiloxanes with a degree of polymerization of 20 or less should be 1
It is desirable that the content be less than or equal to weight%.

By pressing the gasket with the tool,
The pressure difference can be reliably eliminated. 2) It can be reused because it does not damage the lid or container. 3) If a low hardness elastomer is used as the material of the gasket, the hole through the communication pipe will stick, so 0.1
Withstanding a pressure difference of about kg / cm 2 , it can withstand reuse without problems.
