Description
本発明は保冷剤の使用方法に関する。
The present invention relates to a method for using ice packs.
スーパーやデパート等の店舗で購入された食品等は、購入者が自宅等に運ぶまでの間、品質が低下しないように保冷される。そのため、保冷剤（保冷材、蓄冷剤、蓄冷材などともいう）が広く使用されている（例えば、特許文献１等）。
Foods purchased at stores such as supermarkets and department stores are kept cold so that the quality does not deteriorate until the purchaser brings them home. Therefore, cold insulators (also referred to as cold insulators, cold storage agents, cold storage materials, etc.) are widely used (for example, Patent Document 1, etc.).
保冷剤は一定温度を長時間保つことが求められる。
Cooling agents are required to maintain a constant temperature for a long time.
ここで、適切な保冷温度は食材によって異なる。厚生労働省の大量調理施設衛生管理マニュアル（別添１）では冷凍食品が－１５℃以下、生鮮魚介類が５℃以下、食肉が１０℃以下、生鮮果実・野菜が１０℃前後と定められている。また、冷蔵庫は概ね－２４℃、－４℃、＋１２℃の３種類の温度に管理されている。また、要冷蔵品は食材に限定されず、例えば、ワクチン等も含み、適切な保冷温度は要冷蔵品によって異なる。保冷剤の温度は保冷剤の材料に固有であるため、要冷蔵品ごとに適温で保冷するには、複数種類の保冷剤が必要である。しかし、要冷蔵品ごとに適切な保冷温度を長時間保つことができる保冷剤を複数種類開発することは容易ではない。また、保冷剤自身の保管温度も保冷剤に固有であるため、保冷剤に適する温度での、保冷剤の輸送・保管システムを複数種類構築することも容易ではない。
Here, the appropriate cold storage temperature varies depending on the ingredients. According to the Ministry of Health, Labor and Welfare's Hygiene Management Manual for Mass Cooking Facilities (Attachment 1), frozen foods are set at -15°C or below, fresh seafood at 5°C or below, meat at 10°C or below, and fresh fruits and vegetables at around 10°C. . In addition, refrigerators are generally controlled at three temperatures: -24°C, -4°C, and +12°C. In addition, items requiring refrigeration are not limited to foodstuffs, and include, for example, vaccines, etc., and the appropriate cold storage temperature varies depending on the items requiring refrigeration. Since the temperature of the cooling agent is unique to the material of the cooling agent, multiple types of cooling agents are required in order to keep each item requiring refrigeration at an appropriate temperature. However, it is not easy to develop multiple types of ice packs that can maintain an appropriate cold storage temperature for each item requiring refrigeration for a long time. In addition, since the storage temperature of the cooling agent itself is also unique to the cooling agent, it is not easy to construct multiple types of transportation/storage systems for the cooling agent at temperatures suitable for the cooling agent.
本発明は上記実状を鑑みてなされたものであり、本発明の目的は、保冷剤とその輸送・保管システムを複数種類開発、構築することなく、要冷蔵品ごとの適切な保冷温度を長時間容易に保つことができる保冷剤の使用方法を提供することである。
The present invention has been made in view of the above actual situation, and an object of the present invention is to maintain an appropriate cold storage temperature for each item requiring refrigeration for a long time without developing and constructing multiple types of cold insulating agents and their transportation and storage systems. To provide a method for using a cooling agent which can be easily kept.

本開示の保冷剤の使用方法によると、少なくとも一つの保冷剤は、表面温度が－１０℃以下であり、第３の工程で断熱カバーを使用しないことを選択すると、断熱カバーで覆われない領域では－１０℃以下の第１の保冷温度を提供することができる。また、第１の断熱カバーの、少なくとも一つの第１領域は第１の断熱材で構成され、第２の断熱カバーの、少なくとも一つの第２領域は第２の断熱材で構成される。第１の断熱材は第２の断熱材よりも熱伝導率が高い。第３の工程で断熱カバーを使用することを選択すると、少なくとも一つの断熱カバーが装着された少なくとも一つの保冷剤は、第１の断熱材で覆われる第１領域では第１の保冷温度より高い第２の保冷温度を提供し、第２の断熱材で覆われる第２領域では第２の保冷温度より高い第３の保冷温度を提供することができる。保冷剤は表面温度が－１０℃以下の１種類でよいため、保冷剤とその輸送・保管システムを複数種類開発、構築する必要がなく、開発コストを大幅に低減することができる。また、量産効果により製造コストを大幅に低減することができる。さらに、断熱カバーを装着して使用するため、表面温度が－１０℃以下の保冷剤の使用時間を延長させることができるとともに、保冷剤表面への結露を低減することもできる。
According to the method of using the cooling agent of the present disclosure, at least one cooling agent has a surface temperature of −10° C. or less, and if it is selected not to use the heat insulating cover in the third step, the area not covered by the heat insulating cover can provide a first cold storage temperature of -10°C or lower. At least one first region of the first heat insulating cover is made of the first heat insulating material, and at least one second region of the second heat insulating cover is made of the second heat insulating material.

A second cold storage temperature can be provided, and a third cold storage temperature higher than the second cold storage temperature can be provided in a second region covered with a second heat insulating material. Since only one type of ice pack with a surface temperature of -10°C or less is required, there is no need to develop and build multiple types of ice packs and their transportation and storage systems, and development costs can be greatly reduced. In addition, the manufacturing cost can be greatly reduced due to the effect of mass production. Furthermore, since the cooling agent is used with the heat insulating cover attached, it is possible to extend the usage time of the cooling agent whose surface temperature is -10° C. or less, and to reduce dew condensation on the surface of the cooling agent.

When the product requiring refrigeration is, for example, fresh fruits and vegetables, the third cold storage temperature is preferably 5 to 15°C, more preferably 7 to 13°C, and even more preferably 8 to 12°C. The first heat insulating cover 12 may be composed of a material other than the first heat insulating material 14 except for the first region, or may not be composed of any material except for the first region. The second heat insulating cover 13 may be made of a material other than the second heat insulating material 15 except for the second region, or may not be made of any material except for the second region.
保冷剤１０は表面温度が第１の保冷温度の１種類でよいため、保冷剤１０とその輸送・保管システムを複数種類開発、構築する必要がなく、開発コストを大幅に低減することができる。また、量産効果により製造コストを低減することができる。さらに、断熱カバー１１を装着して使用するため、表面温度が第１の保冷温度の保冷剤１０の使用時間を延長できるとともに、保冷剤表面への結露を低減することもできる。
Since only one type of cooling agent 10 having a surface temperature of the first cooling temperature is sufficient, there is no need to develop and construct multiple types of cooling agents 10 and their transportation and storage systems, and development costs can be greatly reduced. Moreover, the manufacturing cost can be reduced due to the effect of mass production. Furthermore, since the heat insulating cover 11 is attached and used, the cooling agent 10 whose surface temperature is the first cooling temperature can be used for an extended time, and dew condensation on the surface of the cooling agent can be reduced.
第１の断熱カバー１２は、第１の断熱材１４で構成され、第２の断熱カバー１３は、第２の断熱材１５で構成されることが好ましい。断熱カバー１１を装着しない保冷剤１０は第１の保冷温度を提供することができる。第１の断熱材１４で構成される第１の断熱カバー１２が装着された保冷剤１０は、第１の保冷温度より高い第２の保冷温度を提供することができる。第２の断熱材１５で構成される第２の断熱カバー１３が装着された保冷剤１０は、第２の保冷温度より高い第３の保冷温度を提供することができる。断熱カバー１１を取り替えることにより、保冷剤１０によって提供する保冷温度を第１の保冷温度、第２の保冷温度、第３の保冷温度のいずれかに簡単に切り替えることができる。
It is preferable that the first heat insulating cover 12 is made of the first heat insulating material 14 and the second heat insulating cover 13 is made of the second heat insulating material 15 . The cold insulator 10 without the heat insulation cover 11 can provide the first cold storage temperature. The cold insulator 10 to which the first heat insulating cover 12 made of the first heat insulating material 14 is attached can provide a second cold insulating temperature higher than the first cold insulating temperature. The cold insulator 10 to which the second heat insulating cover 13 made of the second heat insulating material 15 is attached can provide a third cold insulating temperature higher than the second cold insulating temperature. By replacing the heat insulation cover 11, the cold insulation temperature provided by the cold insulation agent 10 can be easily switched to any one of the first cold insulation temperature, the second cold insulation temperature, and the third cold insulation temperature.
