  The ozone ice 51 can be manufactured by freezing water containing ozone (ozone water). When the ozone ice 51 is manufactured, if it takes a long time to freeze the ozone water, the ozone dissolved in the ozone water is vaporized before the ozone water freezes. Therefore, the ozone ice 51 containing ozone at a high concentration is manufactured. For this purpose, it is necessary to freeze ozone water in a short time. Specifically, ozone ice can be obtained by freezing ozone water under a pressure condition of about 0.5 MPa for about 25 minutes. In the present embodiment, the shape of the ozone ice 51 is a substantially cylindrical shape, but is not limited thereto, and may be any shape such as a polyhedral shape including a cubic shape, a rectangular parallelepiped shape, and a spherical shape.

According to the ultrasonic welding, the three end edges of the bag body 52 can be reliably sealed without causing cracks.

  When the three end edges (the first sealing portion 52A, the second sealing portion 52B, and the opening 52C) of the bag body 52 are sealed by ultrasonic welding, the bag body 52 is made of polypropylene fiber. It is preferable that it is comprised with the nonwoven fabric. Since the bag body 52 is made of a nonwoven fabric made of polypropylene fiber, it can be easily sealed by ultrasonic welding.

Woven or basis weight of the nonwoven fabric constituting the bladder 52 is preferably 30 to 50 g / ^{m 2,} it is preferred that particularly 40~45g / ^{m 2.} If the weight per unit area is less than 30 g / m ² , the water resistance of the bag body 52 may be low and water leakage may occur, and if it exceeds 50 g / m ² , the air permeability will be low and ozone will sufficiently permeate the bag body 52. It may not be possible.

Further, air permeability of the woven or nonwoven fabric constituting the bladder 52 is preferably from 40~48cc / sec / cm ^2, is preferably particularly 43~45cc / sec / cm ^2. If the air permeability of the bag 52 is less than 40 cc / sec / cm ² , a sufficient amount of ozone may not be transmitted. If it exceeds 48 cc / sec / cm ² , ozone ice melts and water leaks out. May occur.

Furthermore, the water pressure resistance of woven or non-woven fabric constituting the bladder 52 is preferably at 525mmH ₂ O or more, preferably at particular 540mmH ₂ O or more, more preferably from 550~560mmH ₂ O . If the water pressure resistance of the bag body 52 is less than 525 mmH ₂ O, ozone ice may melt and water may leak out.

  The bag body 52 may have a configuration in which a plurality of woven fabrics or nonwoven fabrics as described above are stacked. By adopting such a configuration, the bag body 52 is formed so as to transmit ozone more and not transmit water more, and is formed with higher strength. Accordingly, since the ozone ice package 5 does not leak water out of the ozone ice package 5 even when the ozone ice 51 is melted, the content 4 (for example, sashimi or the like) that is not preferably brought into contact with water. Can be stored in the heat insulating container 3 together with the contents 4. Thereby, the freshness of the said content 4 can be maintained and corrosion can be prevented.

  The cold storage material 6 includes a refrigerant storage body and a refrigerant storage body container that houses the refrigerant storage body. As the refrigerant storage body, any material may be used as long as it is in a gel or liquid state at room temperature and is solidified by freezing.

  The refrigerant storage container is not particularly limited as long as it is made of an impermeable base material, but is preferably a nonwoven fabric made of rayon fiber or the like, for example. Even if the cool storage material 6 is stored in the heat insulation container 3 because the refrigerant storage container is formed of a nonwoven fabric made of rayon fiber, the rayon fiber absorbs moisture in the heat insulation container 3 and Condensation can be prevented from occurring.

  Therefore, by storing such a cold storage material 6 in the heat insulating container 3, even the contents 4 that are not preferable to be wet with water can be stored under suitable temperature conditions, The freshness of the object 4 can be maintained and corrosion can be prevented.
