As shown in FIG. 9, a metal (for example, stainless steel) inner container 1A and an outer container 1B are joined to each other on the mouth 2 side to form a double container 1, and a space portion formed between them. There is a structure in which the exhaust port 12 is sealed by a sealing plate 30 through a brazing material (for example, a metal brazing material) after the vacuum exhausting of 3 is performed (see, for example, JP-A-3-267023).

Therefore, it is difficult to position the sealing plate 30 with respect to the exhaust port 12 and evenly dispose the brazing material on the edge portion of the exhaust port 12. In addition, the brazing material having a large diameter of the exhaust port 12 and a large welding area is used. Since it becomes difficult to secure the welding accuracy due to, there is a problem in the reliability of the sealing accuracy.

A storage recess 9 having a small-diameter exhaust port 12 is formed at the bottom of the storage recess 9, a rod-shaped glass sealing material 10 is stored in the storage recess 9, and the glass sealing material 10 is evacuated in a vacuum exhaust chamber. The exhaust port 12 formed by melting and forming in the storage recess 9 is sealed with molten glass.

The carrier is placed on a carrier frame, transferred to a vacuum exhaust chamber, and vacuum-sealed while moving in the vacuum exhaust chamber. At that time, the glass sealing material 10 holds the storage recess 9 while the carrier frame is moving. There is a possibility that it may fall off from the chamber and vacuum sealing may not be possible.

An accommodating recess for accommodating the solid sealing material is formed, and an exhaust port is formed at the bottom of the accommodating recess, which is sealed by the retention of the sealing material that melts down during vacuum evacuation. Since a drop-out prevention member for preventing the contained solid sealing material from falling off is provided in the opening of the carrier frame, the double container is placed upside down and the sealing material is housed in the storage recess, and is then placed on the carrier frame. Even if the carrier frame swings when it is placed and transferred, the sealing material does not drop from the predetermined position due to the presence of the drop-preventing member.
It has an excellent effect that it greatly contributes to the improvement of the sealing accuracy and the automation of the sealing work.

This also makes it possible to reduce the degree of reduction in tensile strength of the container base material, reduce the thickness of the container base material as much as possible, and reduce the weight and cost of the product.

At the same time, a storage recess having an exhaust port that is sealed by the retention of the sealing material that melts during vacuum evacuation is formed at the bottom, and a powdery or granular glass sealing material is formed with peroxide as the sealing material. Since the paste-like sealing material that has been kneaded is used, it is possible to prevent the paste-like sealing material from coming into close contact with the storage concave portion without providing a drop-off prevention member, and to prevent peroxides when the sealing material melts. As a result, a strong oxide film is formed on the metal surface due to the oxidative action of nascent oxygen generated from, which has an excellent effect of significantly improving the adhesiveness of the melt-sealing material.

A ventilation part 14 is formed which communicates the inside of the storage recess 9 with the outside. The ventilation part 14 allows hot air to enter the housing recess 9 during vacuum evacuation, so that the sealing material 10 housed in the housing recess 9 can be heated and melted. Has become. In the present embodiment, the sealing material 10 is stored by lifting the free end of the drop-preventing member 13 after fixing the drop-preventing member 13.

The double container 1 housed inside is loaded on a carrier frame and transferred to the vacuum exhaust chamber, and in the process of being transferred in the vacuum exhaust chamber, first, at a temperature lower than the melting point of the sealing material 10, the exhaust port 12 is opened. After the air between the inner and outer containers 1A and 1B is degassed (that is, baked), it is heated (that is, sealed) at a temperature higher than the melting point of the sealing material 10. As a result, the sealing material 10 melts and flows downward, reaches the exhaust port 12 by being guided by the funnel-shaped recess 11, and stays there.
As shown by reference numeral 10 'in FIG. 3, the exhaust port 12 is reliably sealed.

うことはない。That is, in the case of this embodiment, even if the carrier frame oscillates when the sealing material 10 is accommodated in the accommodation recess 9 and is transferred on the carrier frame.
The presence of the fall-off preventing member 13 prevents the sealing material 10 from dropping from a predetermined position, which greatly contributes to improvement of sealing accuracy and automation of sealing work. In addition, the presence of the ventilation portion 14 allows hot air during vacuum evacuation to easily enter the storage recess 9 in which the sealing material 10 is stored. Therefore, the presence of the fall prevention member 13 inhibits melting of the sealing material 10. There is no such thing.
