2. Description of the Related Art Conventionally, a sealed container for the above-mentioned applications has been insufficient in holding performance of a sealed state when the atmospheric pressure changes due to air transportation or the like. The container was alleviated, and the container could be opened without the need to release the seal. However, there was a drawback that dust in the atmosphere easily entered the container during transportation or the like, thereby contaminating the items to be stored.

However, as the sealing structure of the container has been improved recently, it may take several days for the pressure difference generated during transportation of the aircraft to be reduced. Further, when the container is hermetically sealed under reduced pressure, the lid (and / or the container) is difficult to open by being pressed against the container (and / or the lid) by the atmospheric pressure. Therefore, an object of the present invention is to provide a sealed container that can quickly open the lid when necessary even when the inside of the container is sealed under reduced pressure, and an opening method using the sealed container.

In the hermetically sealed container shown in FIG. 1, the lid 1 and the container 2 are fitted to each other with a gasket (not shown) sandwiched between the opening peripheral portions 3 and 4 and locked by appropriate means. In the first embodiment shown in FIG.
Each of the opening peripheral portions 3 and 4 has a double wall structure in which the inner and outer side walls are provided so as to protrude, and has a cross section h-shaped, T-shaped, X-shaped in a gap formed therebetween. The lid 1 and the container 2 are fitted together by interposing a gasket 5 of an arbitrary shape such as a W-shape in a state of being in close contact with the surrounding wall surface and bringing the tip portions of the outer walls 6 and 7 into contact with each other.・ It is sealed. Reference numeral 8 denotes a hole penetrating through the outer wall of the opening peripheral portion 3 of the fitting / sealing portion, and reference numeral 11 denotes a notch provided correspondingly in front of the hole 8 on the inner wall thereof. Reference numeral 9 denotes a communication pipe such as an injection needle for releasing the state when opening and closing of the lid becomes difficult due to a pressure difference between the inside and outside of the sealed container.
Insert through the hole 8, penetrate the gasket 5, and cut the tip
This is achieved by inserting into the vessel from the notch 11 and conducting or injecting air into the vessel. At this time, if there is a possibility that the stored items may be contaminated by the inflow of outside air, it can be prevented by attaching a dustproof filter 10 to the entrance of the communication pipe 9. Further, by pressurizing the inside of the container to a pressurized state with a press-fitting device such as a syringe, the fitting between the lid 1 and the container 2 can be released by (air) pressure.

How the holes 8 and the notches 11 are provided differs depending on the structure of the opening peripheral portions 3 and 4 and the cross-sectional shape of the gasket as in the embodiments shown in FIGS .
The positions of these holes 8 or notches 11 are
May be anywhere in the set only if only phase-corresponding with the inner and outer side walls around, it is possible to seal release if the size is also greater than the dimensions of the communicating pipe 9. However, if the hole 8 or the notch 11 is provided at the seal point or the gasket 15 is large enough to be deformed, it is natural that a problem occurs in the function. If the gasket 15 is not always exposed depending on the application, a plug 13 can be provided in the hole 8 as shown in FIG. 4 ( c ). FIG.
In the fifth embodiment shown in FIG. 5 , an O-ring having a circular cross section is used as the gasket 25. Both inner and outer side walls of the opening peripheral edges 3, 4 are projected, and the gasket 25 is inserted into a gap formed therebetween. wear, and Ru Oh those was provided a structure in which the notches reaching the respective inner and outer side walls to the surface of the gasket phases correspondingly.

The use of an elastomer having a low hardness of is preferred from the viewpoint of sealing performance. Examples of such an elastomer include silicone rubber and styrene-based, olefin-based, and polyester-based thermoplastic elastomers. When silicone rubber is used for the gasket, volatile components contaminate the contents. Therefore, among the low-molecular-weight polysiloxanes, those having a polymerization degree of 20 or less as the silicone rubber have a total amount of 1% by weight or less. desirable.
