A structure is provided in which a packing body containing powder or other powder is housed, and in this housed state, air is evacuated from the inside of the outer shell and hermetically sealed, thereby maintaining the inside in a vacuum state. has been done.

多いものである。However, in the above configuration, when the inside of the outer shell, that is, the filling body is evacuated, the air between the powder particles is exhausted through the inner bag, so the resistance that air receives when passing through the inner bag is large. There was a drawback that the time required for evacuation was longer. However, if the inner bag is made thinner to increase air permeability in order to shorten the evacuation time, the powder will pass through the inner bag and be sucked into the vacuum pump. There is a risk of damaging the In addition, the average particle size of the powder is usually 1
Since the particle size is approximately 0 to 20 μm, handling of such powdered materials is difficult in terms of workability and poses many problems in terms of health and safety.

is a filling body housed inside the outer shell 1, which is made of, for example, calcium silicate plate crystal powder (trade name "Fluorite R").
: Manufactured by Tokuyama Kashitatsu Co., Ltd., a porous molded material formed into a flat plate shape by pressurizing and bonding powder consisting of powder with an average particle size of 20μ at a pressure of, for example, 100 kg/(m r). As shown in FIG. The inside of the outer shell 1 is evacuated through the exhaust port 1a.In this case, the inside of the vacuum container 3 is evacuated from the exhaust port 3a by a vacuum pump (not shown), so that the pressure is reduced to, for example, about 1 torr. It has become.

性が向上する。According to this embodiment having such a structure, the filling body 2 is composed of a porous molded body formed by pressurizing powdery bodies and bonding them to each other. There is no need to exhaust the air, and the time required for exhaust can be shortened. Moreover, since the filling body 2 is constructed from a porous molded body formed by pressurizing the powder, the powder leaks out compared to a conventional inner bag that stores the powder. As a result, it is possible to prevent the powder from being sucked into the vacuum evacuation system, particularly the vacuum pump, thereby reducing maintenance of the evacuation system and damage to the vacuum pump. In addition, since most of the powder particles are prevented from leaking out, the powder particles will not adhere to the welded parts of the outer shell 1, and gas leaks due to foreign objects getting caught in the welded parts when the outer shell is welded will be avoided. This can be prevented and the gas barrier properties and welding strength at the welded portion can be improved. Furthermore, since almost no powder material leaks out when the inside of the outer shell 1 is evacuated, a powerful vacuum pump can be used to increase the evacuating speed, speeding up manufacturing and reducing manufacturing costs. be able to. In addition, since the filling body 2 is a porous molded body, it is more safe and hygienic and the handling efficiency is improved compared to the conventional stuff.

Since the filling body 2 is configured by bonding to the powder, the voids between the powder particles become small, so even if a gas leak occurs in the outer shell 1 and the pressure inside the outer shell 1 increases, the thermal conductivity will decrease. Changes are reduced, and the life of the insulation performance of the vacuum insulation panel can be extended.

る。In the above embodiment, the entire filling body 2 is formed from a powder made of calcium silicate plate crystal powder, but the present invention is not limited to this. For example, alumina powder or silica powder may be used as a base, and silicic acid The filler may be constructed from a powder containing 5% by weight or more of calcium platelet crystal powder, and in this case as well, the same effects as in the above embodiment can be obtained.
