質Ａ１合金となる。First, a substrate is prepared which is a porous material and whose surface contains metal ions that are to be diffused and released into the air. This porous material may be any material, but the present inventors used Al
It is a more suitable material because it is easy to form an alloy with At and porous materials can be manufactured from At powder. To provide food with a fresh air atmosphere and a metal ion atmosphere with antibacterial effects, Al (: u, 3i, Mn, Ti, Fe
, AQ, tvlg, Zn, Co, N~10, the AI1 alloy porous material manufactured by an alloy containing 5% by weight or less in total is suitable for various purposes. The experimental results were revealed. The Al porous material is made of 99% by weight of pure Af powder with a particle size of 200 to 500um, and Cu with a particle size of 100μm or less, for example, at a ratio of 1% by weight.
One or more powders of Si, Mn, Ti, and Fe are mixed, and the uniformly mixed powder is uniformly sprinkled on carbon to form a powder that is below the melting point of Al, preferably 610°C, under no pressure.
Obtained by sintering in a N2 H2 mixed gas at ~650°C. This porous material maintains its dispersed shape and becomes a porous A1 alloy having three-dimensional communicating pores containing 40% or more of air.

用が発生する。A box-shaped storage container is made using such materials. For example, food, fruits, vegetables, and stones can be put into this container and stored at room temperature or low temperature. What makes a normal storage container different is that it has very good air permeability, and various ions supported on its surface by air circulation, such as Cu ions, Mn ions, T1 ions, S1 ions, and Fe ions. Alternatively, the antibacterial agents alone or in combination are gradually released into the atmosphere, which creates a fresh atmosphere surrounding the food, allowing the food to be kept sterile for a long period of time. There is a technology that would not have been able to create such a small amount of antibacterial atmosphere without this method, and it does not harm the food at all, keeps it fresh, and allows the food to remain in its original state for a long period of time. The action of preserving the material occurs.

Furthermore, the long-term preservation material of the present invention can be used not only as a container but also as an underlay or a partition for storing perishables to obtain the same effect as when used as a container.
