産業上の利用分野
本発明は、生鮮野菜、果物、冷蔵食品等の輸送や、配送
時に効果的に鮮度を保持するための保鮮断熱段ボール函
に間するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heat-insulating cardboard box for preserving fresh vegetables, fruits, refrigerated foods, etc., for effectively maintaining their freshness during transportation and delivery.
従来の技術
生鮮食品によって、その必要維持温度は異なるが、必要

鮮野菜等を凍らないようにするために使用する。Conventional technology The required maintenance temperature varies depending on the fresh food, but there is a certain range of required maintenance temperature, and an insulated container stores items that have been cooled to a certain lower limit temperature and maintains a certain required cooling temperature. It is used to keep fresh vegetables within a certain range, and conversely, to prevent fresh vegetables from freezing in cold regions.
保温効果を向上させるため、保冷容器として利用する場
合には内部で吸熱する蓄冷剤を使用したり、温熱容器と
して利用する場合には温熱剤が使用される場合もある。In order to improve the heat retention effect, a cold storage agent that absorbs heat internally may be used when used as a cold storage container, or a heating agent may be used when used as a heating container.
従来、簡易で効果的な断熱容器としては一般的に発泡ス
チロール容器が利用されている。Conventionally, a Styrofoam container has generally been used as a simple and effective heat-insulating container.
そして、保鮮剤として、脱酸素剤や、その他のガス吸着
剤を袋詰めにしたものが使用されている。As a freshness preservative, bags containing oxygen absorbers and other gas adsorbents are used.
発明が解決しようとする問題点
従来の発泡スチロール容器は、所定の金型で発泡成形し
た容器本体と蓋とよりなっているが、成形コストが安価
でないばかりでなく、それぞ、れの形状に合わせた高価
な金型を必要とした。Problems to be Solved by the Invention Conventional styrofoam containers consist of a container body and a lid that are foam-molded using a predetermined mold. This required expensive molds.
また、発泡スチロール容器は空箱のときに折り畳むこと
ができないので、輸送や在庫に不便であった。Furthermore, since the Styrofoam container cannot be folded when empty, it is inconvenient for transportation and inventory.
更に、生鮮食品等のワンウェイ用の函として発泡スチロ

器は廃棄処理が負担となり、重大な廃棄公害問題となり
つつある。Furthermore, styrofoam containers are increasingly being used as one-way boxes for fresh foods, etc., but these styrofoam containers are becoming a burden to dispose of, and are becoming a serious disposal pollution problem.
一方、段ボール函は焼却処分も容易であり、その大部分
がリサイクルされる省資源の典型的な包装容器である。On the other hand, cardboard boxes can be easily disposed of by incineration, and most of them are recycled, making them a typical resource-saving packaging container.
しかし、普通の段ボール函で効果的な断熱容器になると
は考えられていないので、近時、段ボールと発泡樹脂シ

ラミネートしたりして保冷容器として使用している場合
が見受けられるが、段熱効果は小さく、リサイクルので
きない高価な函となっている。However, ordinary cardboard boxes are not thought to be effective insulating containers, so in recent years, cardboard boxes have been combined with foamed resin sheets, or cardboard is laminated with aluminum vapor-deposited film to be used as cold containers. However, the heat effect is small and the boxes are expensive and cannot be recycled.
このように現在に至るまでに、段ボールだけを断熱材と
した効果的な断熱容器は得られていない。それは、−重
の段ボール函ではあまり断熱効果がないからである。As described above, to date, an effective heat-insulating container using only cardboard as a heat-insulating material has not been obtained. This is because heavy cardboard boxes do not have much of an insulating effect.

生鮮食品は、一部を除いて水分含量が高いので常温では
急速に微生物が増殖して腐敗する。With the exception of some fresh foods, they have a high moisture content, so microorganisms rapidly multiply and spoil them at room temperature.

生物の生育増殖に不都合な低温環境にするべきである。In order to preserve freshness during storage and transportation of fresh foods, the environment should be kept at a low temperature that is inconvenient for the growth and proliferation of microorganisms.
そのために、生鮮食品は一刻も速く予冷して、低温流通
方式（コールドチェーン）で貯蔵して、移送することが
品質を保持出来ることになる。For this reason, quality can be maintained by pre-cooling fresh foods as quickly as possible, storing and transporting them using a cold chain system.

る。Fruits and vegetables continue to undergo catabolic processes to maintain life even during storage, so they release carbon dioxide and other gases through respiration.
It is oxidized and consumed by discharging moisture, etc., and its quality deteriorates. This effect can be suppressed by lowering the temperature, or by increasing the amount of inert gases such as carbon dioxide or nitrogen gas and decreasing the amount of oxygen, causing the animal to go into a dormant state.

して、呼吸や栗色に形響する。In general, fruits and vegetables are best harvested just before they are exposed to heat, but fruits in particular ripen due to their biological processes, and when they reach full ripeness, their respiratory effects rapidly increase, producing ethylene during ripening, which produces trace amounts of ethylene. However, it acts as an autocatalyst and generates a large amount of gas, which affects breathing and maroon color.
そこで、生鮮食品等を生産地から消費地に輸送し、また

に廃棄処理ができるような保鮮断熱容器の必要度が強ま
っている。Therefore, when transporting fresh foods from production areas to consumption areas, or delivering refrigerated and frozen foods from door to door, it is important to be able to keep the items cool or warm within the appropriate temperature range. Of course, by adsorbing ethylene, oxygen, etc., it has a freshness preservation effect, can reduce costs, and can be folded flat when not being transported, so it does not cause pollution. There is a growing need for insulated, fresh containers that can be disposed of as waste.
そもそも断熱容器は、熱伝導率の小さい材料の壁で密閉
するものである。In the first place, an insulated container is sealed with a wall made of a material with low thermal conductivity.
空気は自然に存在する物質のなかで最も熱伝導率の小さ
い物質であり、移動と、対流がなければ有効な断熱材で
ある。発泡スチロール函が断熱効果を有しているのは隔
離された空気にある。Air has the lowest thermal conductivity of any naturally occurring substance and is an effective insulator in the absence of movement and convection. Styrofoam boxes have an insulating effect because of the isolated air.
段ボールは、表裏のライナーと、中芯フルートと、中芯

も−重の段ボールの函での断熱効果は十分ではない。Corrugated cardboard is made up of front and back liners, a core flute, and air separated by the core flute, so if you use a corrugated board base with a structure that seals the edges in the width direction of the cardboard, it will Although the box itself has an insulating structure, the insulating effect of a heavy cardboard box is still not sufficient.
そこで、本発明の目的とするところは、字面のときには
折り畳むことができて、生鮮食品を容易に梱包すること

熱効果が大きくて、（采鮮効果があり、廃棄公害の無い
、リサイクルできて省資源の、安価な断熱段ボール基を
提供することにある。Therefore, the object of the present invention is to have a structure that can be folded when in its original form, allows for easy packaging of fresh foods, and has a large insulation effect that allows it to maintain the required temperature range for as long as possible. To provide an inexpensive heat-insulating corrugated board board that has a fresh effect, causes no waste pollution, is recyclable, and saves resources.
問題点を解決するための手段
本発明は、かかる目的を達成するために、大きさを異に

である。Means for Solving the Problems In order to achieve the above object, the present invention provides a plurality of corrugated cardboard bases of different sizes and combined into inner and outer layers in multiple layers, and an inner surface of the bottom plate of the outer corrugated base. An auxiliary bottom plate made of cardboard is interposed between the outer surface of the bottom plate of the inner corrugated cardboard base and thickens the air layer at the bottom, and is interposed between the inner surface of the side plate of the outer corrugated cardboard base and the outer surface of the side plate of the inner corrugated cardboard base, Equipped with a side intervening member made of cardboard that thickens the air layer in the wound,
The inner cardboard base has gas adsorption ability.

ができて省資源の、安価な保鮮断熱容器になる。The outer and inner cardboard bases can be folded when in the face. In addition, by interposing the auxiliary bottom plate and side intervening members between the outer cardboard base and the inner cardboard base, the air layer at the bottom and sides is thickened, increasing the thermal resistance inside and outside the box, and creating a heat insulation effect. Since we use cardboard that can increase the size of the gas and has gas adsorption ability,
The freshness of perishable food can be maintained, and since the members are made of cardboard, the container does not cause waste pollution, can be recycled, and is a resource-saving, inexpensive, insulated container.

しかして、本実施例の保鮮断熱段ボール基りを組立てる
には、まず、外側の段ボール基２の底フラツプをガムテ
ープ等で止める。To assemble the heat-preserving and heat-insulating corrugated cardboard base of this embodiment, first, the bottom flap of the outer corrugated cardboard base 2 is secured with duct tape or the like.
次に外側の段ボール基２の内底に、底部介在部材３を挿

四周で介在される。When the inner cardboard base l is inserted, the inner cardboard base l is guided by the inclined guide surface 3c of the bottom intervening member 3 and smoothly rides on the auxiliary bottom plate 3a, and the side intervening part
b are interposed between the inner corrugated cardboard base 1 and the outer corrugated cardboard base 2 on all four sides.
次に内側の段ボール基１の上に天面部介在部材（段ボー
