Description

本発明は、野菜などの農作物の予冷時および出荷時などに好適に用いられる保冷容器と、その保冷容器を備えた差圧式保冷装置に関する。   The present invention relates to a cold storage container suitably used for precooling and shipping of agricultural products such as vegetables, and a differential pressure type cold storage apparatus provided with the cold storage container.

一般に、いちご、にんじん、レタス、ホウレンソウ、ブロッコリー、リンゴなどの各種農作物を遠方へ出荷、輸送するに際しては、これらを断熱性のある容器に収納した状態で差圧予冷法などによる予冷が行なわれ、その状態で物流に供される。差圧予冷法とは、一方に冷気入口を他方に排出口を持つ断熱性のある容器を冷気雰囲気下におき、排出口側をファンなどにより吸引して差圧を生じさせて、冷気を冷気入口から排出口に向けて移動循環させ、容器に収容した物品を所要温度に予冷する方法であり、出荷に当たっては、各保冷容器の物品収容空間を外気から遮断した状態とすることにより、予冷された環境を一定時間維持するようにしている。   In general, when shipping and transporting various crops such as strawberries, carrots, lettuce, spinach, broccoli, and apples to a distant place, they are pre-cooled by a differential pressure pre-cooling method in a state where they are stored in a heat-insulating container, It is used for logistics in that state. In the differential pressure pre-cooling method, a heat-insulating container having a cold air inlet on one side and a discharge port on the other side is placed in a cold air atmosphere, and the discharge side is sucked with a fan or the like to generate a differential pressure. This is a method of moving and circulating from the inlet to the outlet and precooling the articles stored in the container to the required temperature. The environment is maintained for a certain period of time.

特許文献１（実開平５−４０１８０号公報）には、そのような差圧予冷法に用いるのに好適な保冷容器が記載されている。この保冷容器は全体が合成樹脂発泡体で作られており、図７に示すように、箱形の容器本体１と蓋２とからなる。蓋２は、容器本体１の上方開口側の左右の側壁内側に形成された段差部３の上にその両側縁を載せた状態で、図で左右方向にスライドするようになっており、必要時には、最も右側までスライドさせることにより、容器本体１から蓋２を取り外すことができる。   Patent Document 1 (Japanese Utility Model Laid-Open No. 5-40180) describes a cold storage container suitable for use in such a differential pressure precooling method. The whole cold storage container is made of a synthetic resin foam, and includes a box-shaped container body 1 and a lid 2 as shown in FIG. The lid 2 slides in the left-right direction in the figure with its both side edges placed on the stepped portion 3 formed inside the left and right side walls on the upper opening side of the container body 1. The lid 2 can be removed from the container body 1 by sliding it to the rightmost side.

容器本体１の前方側壁には第１の切り欠き４が形成され、後方側壁には第２の切り欠き５が形成されている。一方、蓋２の先端には第１の切り欠き４を閉鎖することのできる突出部６が形成され、後端には第２の切り欠き５を閉鎖することのできる垂下突部７が形成されている。図７に示すように、蓋２の一部を右方向に引き出した状態では、容器本体１の第１の切り欠き４と第２の切り欠き５は開放した状態、すなわち、外気と連通した状態となる。図示しないが、蓋１を最も左側までスライドさせると、容器本体１の第１の切り欠き４は蓋２とその先端の突出部６により閉鎖され、同時に、第２の切り欠き５は蓋２の垂下突部７により閉鎖される。   A first notch 4 is formed on the front side wall of the container body 1, and a second notch 5 is formed on the rear side wall. On the other hand, a protrusion 6 capable of closing the first notch 4 is formed at the front end of the lid 2, and a hanging protrusion 7 capable of closing the second notch 5 is formed at the rear end. ing. As shown in FIG. 7, in a state in which a part of the lid 2 is pulled out to the right, the first notch 4 and the second notch 5 of the container body 1 are open, that is, in a state of communicating with the outside air. It becomes. Although not shown, when the lid 1 is slid to the leftmost side, the first notch 4 of the container body 1 is closed by the lid 2 and the protruding portion 6 at the tip thereof, and at the same time, the second notch 5 is It is closed by the drooping projection 7.

蓋２を容器本体１から取り外し、容器本体１の物品収容空間８に野菜などを収納した後、蓋２を容器本体１の段差部３にその両側縁を載せた状態とし、左方向に停止するまでスライドさせる。それより、物品収容空間８は外気から閉鎖された状態となる。その状態の保冷容器を、必要な場合には多段に積み上げて、保冷倉庫のような冷気雰囲気内に置く。そして、蓋２を図で右方向にスライドさせて引き出し、図７の状態とすると共に、開放した第１の切り欠き４または第２の切り欠き５のいずれか一方を吸引ファンのような適宜の吸引手段側に接続する。   After removing the lid 2 from the container body 1 and storing vegetables or the like in the article housing space 8 of the container body 1, the lid 2 is placed on the stepped portion 3 of the container body 1 with its both side edges placed on it and stopped to the left. Slide until As a result, the article storage space 8 is closed from the outside air. The cold storage containers in that state are stacked in multiple stages if necessary and placed in a cold atmosphere such as a cold storage warehouse. Then, the lid 2 is slid rightward in the drawing and pulled out to be in the state shown in FIG. 7, and either the opened first notch 4 or the second notch 5 is appropriately set like a suction fan. Connect to the suction means.

それにより、冷気雰囲気である外気と物品収容空間８との間に差圧が生じ、冷気は開放したいずれか一方の切り欠きから物品収容空間８に流入する。収容物品を冷却した冷気は吸引手段により物品収容空間８から引き抜かれ、他方の切り欠きから流出する。必要な場合には図示しない冷却手段で再度冷却されて、冷気雰囲気内に戻される。所要時間、冷気の循環を継続することにより、収容物品は所要に冷却される。   As a result, a differential pressure is generated between the outside air that is a cold air atmosphere and the article housing space 8, and the cold air flows into the article housing space 8 from one of the opened notches. The cold air that has cooled the stored article is drawn out of the article storage space 8 by the suction means and flows out from the other notch. If necessary, it is cooled again by a cooling means (not shown) and returned to the cold atmosphere. By continuing the circulation of the cold air for the required time, the contained article is cooled as required.

冷却後に、収容物品を物流に供する場合には、蓋２を左端まで押し込んで、物品収容空間８を外気から遮断した状態とし、保冷容器を保冷倉庫のような冷気雰囲気から取り出す。そして、そのまま他の場所へ移送する。保冷容器は全体が合成樹脂発泡体製であり断熱性に富み、かつ、物品収容空間８は外気から遮断された状態にあるので、野菜などの収容物品の保冷状態は長期にわたり維持される。
実開平５−４０１８０号公報 When the stored articles are used for distribution after cooling, the lid 2 is pushed to the left end so that the article storage space 8 is cut off from the outside air, and the cold storage container is taken out from the cold atmosphere such as a cold storage warehouse. And it transfers to another place as it is. Since the entire cold insulation container is made of synthetic resin foam and has high heat insulation properties, and the article storage space 8 is in a state of being shielded from the outside air, the cold storage state of the stored articles such as vegetables can be maintained for a long time.
Japanese Utility Model Publication No. 5-40180

上記の保冷容器は、物品収容空間内に隙間のある状態で冷却しようとする物品が収容されている場合には、差圧保冷用の容器として効果的に機能する。しかし、菜の花のように葉の多い野菜などが密に物品収容空間内に収容されているような場合に、流入した冷気は、物品の内部あるいは容器底面まで入り込むことなく、蓋の裏面に沿って出口までストレートに流れてしまうことが起こり得る。その場合、収容した物品は蓋に近接した部分のみが冷却されることとなり、全体が均一に予冷されなくなる。   The above cold storage container effectively functions as a differential pressure cold storage container when an article to be cooled is stored in the article storage space with a gap. However, when vegetables with many leaves, such as rape blossoms, are densely accommodated in the article storage space, the inflowing cold air does not enter the interior of the article or the bottom of the container, but along the back of the lid. It can happen that it flows straight to the outlet. In that case, only the part close to the lid of the stored article is cooled, and the whole is not precooled uniformly.

また、多段に段積みした状態でも各保冷容器の蓋はスライド可能であり、個々の保冷容器毎に蓋の開け閉め操作を行うことができるが、例えば、作業者が蓋の一部を引き出して冷気を導入しようとするときに、引き出し距離にバラツキが生じる恐れがある。その場合、冷気の導入量が容器毎に変化して、均一な予冷が得られなくなる。また、蓋は単に容器本体の上に載った状態であり、物流時などにおいて、不用意に蓋が外れてしまうことが起こりやすい。   In addition, the lid of each cold storage container can be slid even when stacked in multiple stages, and the lid can be opened and closed for each cold storage container. For example, an operator pulls out a part of the lid. When trying to introduce cold air, there is a possibility that the pull-out distance varies. In that case, the amount of cool air introduced varies from container to container and uniform pre-cooling cannot be obtained. In addition, the lid is simply placed on the container body, and the lid is likely to be inadvertently removed during distribution.

本発明は、上記のような事情に鑑みてなされたものであり、例えば差圧予冷に使用する場合に、収容物品の収容状態に左右されることなく、収容物品空間内に導入される冷気が収容物品の周囲全体に行き渡るようにして、冷却ムラが生じるのを効果的に回避できるようにした、改良された保冷容器を提供することを目的とする。   The present invention has been made in view of the above circumstances. For example, when used for differential pressure pre-cooling, the cold air introduced into the accommodation article space is not affected by the accommodation state of the accommodation article. It is an object of the present invention to provide an improved cold-reserving container that can effectively avoid the occurrence of uneven cooling by spreading over the entire periphery of the stored article.

本発明は、また、複数の保冷容器を同じ冷気雰囲気に置いて予冷をする場合に、すべての保冷容器内に等しい量の冷気が流入するように、容易に蓋の引き出し量を所定距離に設定できるようにした、改良された保冷容器を提供することを目的とする。   In the present invention, when a plurality of cold containers are placed in the same cold atmosphere and pre-cooled, the amount of the lid is easily set to a predetermined distance so that an equal amount of cold air flows into all the cold containers. An object of the present invention is to provide an improved cold storage container that can be used.

本発明は、また、不用意に蓋が容器本体から分離するのを阻止できるようにした改良された保冷容器を提供することを目的とする。   Another object of the present invention is to provide an improved cold insulated container that can prevent the lid from being inadvertently separated from the container body.

さらに、本発明は、上記した改良された保冷容器を備えた差圧式保冷装置を提供することを目的とする。   Furthermore, an object of the present invention is to provide a differential pressure type cold insulation apparatus provided with the above-described improved cold insulation container.

上記の課題を解決するための本発明による保冷容器は、容器本体の上方開口側にスライド式の開閉蓋を備え、蓋を最も押し込んだ状態では容器本体の物品収容空間は閉じた状態となり、蓋の一部を引き出した状態では前記物品収容空間は蓋のスライド方向の前後の２箇所において外部に連通した状態となるようにされた合成樹脂発泡体よりなる保冷容器であって、蓋の裏面には物品収容空間内に入り込む冷気を容器本体の底面に向けて案内するための冷気案内用突起が形成されていることを特徴とする。   A cold storage container according to the present invention for solving the above-mentioned problems is provided with a slide-type opening / closing lid on the upper opening side of the container body, and when the lid is pushed in most, the article storage space of the container body is closed. In a state in which a part of the article is pulled out, the article storage space is a cold storage container made of a synthetic resin foam that is in communication with the outside at two locations in the front and rear of the lid sliding direction. Is characterized in that a cold air guide projection for guiding the cold air entering the article storage space toward the bottom surface of the container body is formed.

上記の保冷容器では、外部に連通した一方の連通部から物品収容空間内に流入する冷気は、蓋の裏面に形成された冷気案内用突起に衝突して流れ方向が強制的に下方に向けられる。そのために、密な状態で収容物品が収容されている場合でも、冷気は物品間の隙間を通過して下方に向けて流下する。それにより、収容物品に冷却ムラが生じるのを効果的に回避することができる。冷気案内用突起は一段のみであってもよく、複数段に形成されてもよい。   In the above cold storage container, the cold air flowing into the article housing space from one communicating portion communicating with the outside collides with the cold air guiding projection formed on the back surface of the lid, and the flow direction is forced downward. . Therefore, even when the stored article is stored in a dense state, the cold air flows downward through the gap between the articles. Thereby, it is possible to effectively avoid the occurrence of cooling unevenness in the stored article. The cold air guide protrusion may be formed in only one stage or may be formed in a plurality of stages.

本発明による保冷容器において、好ましくは、その内周面に冷気を案内するための凹溝がさらに形成される。凹溝は側壁面の内周面にのみ形成されてもよく、底面にも連続した状態で凹溝が形成されていてもよい。収容物品同士の間に隙間があまりない状態のときでも、冷気は内周面に形成した凹溝を流路として、側面および底面から収容物品同士の隙間に入り込むようになるので、冷却ムラが生じるのはさらに効果的に回避できる。   In the cold insulation container according to the present invention, preferably, a concave groove for guiding cold air is further formed on the inner peripheral surface thereof. The concave groove may be formed only on the inner peripheral surface of the side wall surface, or the concave groove may be formed on the bottom surface in a continuous state. Even when there are not many gaps between the stored articles, the cooling air enters into the gaps between the stored articles from the side surface and the bottom surface using the recessed grooves formed on the inner peripheral surface as a flow path, resulting in uneven cooling. This can be avoided more effectively.

本発明による保冷容器において、好ましくは、蓋裏面の上記冷気案内用突起が形成された位置よりも蓋の引き出し方向手前側に、容器本体の側壁に当たってそれ以上の蓋の引き出しを規制するための第２の突起が形成される。第２の突起を備えることにより、蓋の引き出し量は、作業者の個人差に左右されずに一定となるので、多数の保冷容器を同じ冷気雰囲気下に置いて差圧保冷を行う場合に、保冷容器単位で冷却ムラが発生するのを効果的に回避することができる。   In the cold storage container according to the present invention, it is preferable that the first side for restricting further pulling out of the lid by striking the side wall of the container body closer to the front side in the pulling direction of the lid than the position where the cold air guiding projection is formed on the back surface of the lid. Two protrusions are formed. By providing the second protrusion, the amount of the lid pulled out is constant regardless of the individual difference of the operator, so when performing differential pressure cold storage with a large number of cold containers placed in the same cold atmosphere, It is possible to effectively avoid the occurrence of uneven cooling in units of cold storage containers.

本発明は、さらに、上記したいずれかの保冷容器の複数個が冷気雰囲気中に備えられ、各保冷容器の外気に連通することとなる２つの連通部のうちのいずれか一方は共通の吸引手段に接続している差圧式保冷装置をも開示する。予冷する目的で保冷容器内に収容する物品は任意であるが、いちご、にんじん、レタス、ホウレンソウ、ブロッコリー、リンゴのような農作物であることは好ましく、このような農産物に対して、本発明による差圧式保冷装置が最も効果的に機能する。   In the present invention, a plurality of any one of the above described cold storage containers is provided in a cold air atmosphere, and any one of the two communication portions that communicate with the outside air of each of the cold storage containers is a common suction means. Also disclosed is a differential pressure-type cold insulation device connected to the. The articles stored in the cold storage container for the purpose of pre-cooling are optional, but are preferably crops such as strawberries, carrots, lettuce, spinach, broccoli, and apples. A pressure-type cooler works most effectively.

本発明による差圧予冷用の保冷容器を用いることにより、収容物品の収容状態に左右されることなく、冷却ムラのない状態で、所要の予冷状態を得ることができる。また、複数の保冷容器を同じ冷気雰囲気に置いて予冷をする場合にも、保冷容器単位で冷却ムラが発生するのを効果的に回避することができる。さらに、不用意に蓋が容器本体から分離することがないので、物流時などでの保冷容器の取り扱いがきわめて容易となる。   By using the cold storage container for differential pressure pre-cooling according to the present invention, the required pre-cooling state can be obtained without being affected by the cooling unevenness without being influenced by the storage state of the stored articles. Further, even when precooling is performed by placing a plurality of cold storage containers in the same cold air atmosphere, it is possible to effectively avoid occurrence of uneven cooling in units of cold storage containers. Furthermore, since the lid does not inadvertently separate from the container body, handling of the cold storage container at the time of physical distribution becomes extremely easy.

以下、図面を参照して本発明を実施の形態により説明する。図１は本発明による保冷容器の一例を示す斜視図であり、図２は図１に示す保冷容器を閉じた状態で多段に積み上げた状態を斜視図で示しており、図３はそれを断面で示している。また、図４は図１に示す保冷容器の蓋の一部を開いた状態で多段に積み上げた状態を斜視図で示しており、図５はそれを断面で示している。図６は図１に示す保冷容器を複数個冷気雰囲気中に置いて構成される差圧式保冷装置の一例を示す斜視図である。   The present invention will be described below with reference to the drawings.

The concave groove 15 on the inner peripheral surface of the side wall reaches the bottom surface in the vertical direction, and is formed so that continuous concave grooves also intersect with the bottom surface. The opening side of the front side wall 11 and the left and right side walls 13, 14 is a stepped portion 16 that is cut out on the inner side, and the rear side wall 12 has an upper end surface that is the same height as the stepped portion 16. Further, the rear side wall 12 is located inside the rear end portions 13a, 14a of the left and right side walls 13, 14.

前側壁１１の上縁側には前記段差部１６までには達しない第１の切り欠き１７が形成され、後側壁１２の上縁側にも第２の切り欠き１８が形成されている。また、左右の側壁１３，１４の前記段差部１６の側面部分には、後記する蓋３０に形成した張出部３３の張り出し距離とほぼ同じ深さの縦方向の凹陥部１９が、前記張出部３３と同じ間隔で複数個形成されており、該凹陥部１９と凹陥部１９との間の側面部分には段差部１６から一定の距離だけ上方位置に複数個の凸片２０が形成されている。なお、図１で、２１は前側壁１１と後側壁１２の下端に形成された凹所であり、保冷容器Ａを持ち運びするときに手をかける部分として利用される。   A first notch 17 that does not reach the stepped portion 16 is formed on the upper edge side of the front side wall 11, and a second notch 18 is also formed on the upper edge side of the rear side wall 12. In addition, on the side surface portions of the step portions 16 of the left and right side walls 13 and 14, the vertical recessed portions 19 having substantially the same depth as the overhang distance of the overhang portion 33 formed on the lid 30 described later are provided in the overhang. A plurality of protruding pieces 20 are formed at a certain distance from the stepped portion 16 on the side surface portion between the recessed portion 19 and the recessed portion 19. Yes. In FIG. 1, reference numeral 21 denotes a recess formed at the lower ends of the front side wall 11 and the rear side wall 12, and is used as a part to be put on when carrying the cold insulation container A.

蓋３０は、その左右の側縁領域を容器本体１０に形成した前記段差部１６に載せた状態で前後方向に自由にスライドできる横幅を有し、かつ、左右の側縁３１，３２には一定の間隔をおいて複数個の張出部３３を備えている。蓋３０の前後方向の長さは、スライドさせながら蓋３０を最も奥まで、すなわち、その前方端３４が容器本体１０の前側壁１１の前記切り欠かれた部分の側面部分２２に衝接した状態で、後方端部３５が容器本体１０の左右の側壁１３，１４の後方端部１３ａ，１４ａに一致する長さとされている。また、蓋３０の厚さは、前記段差部１６に載せた状態で、蓋の表面が容器本体１０の側面上端面よりも下位の位置となるようにされる（図３も参照）。   The lid 30 has a lateral width that allows the left and right side edge regions to slide freely in the front-rear direction while being placed on the stepped portion 16 formed in the container body 10, and the left and right side edges 31, 32 have a fixed width. A plurality of overhang portions 33 are provided at intervals of. The length of the lid 30 in the front-rear direction is such that the lid 30 is moved to the farthest side while sliding, that is, the front end 34 is in contact with the side surface portion 22 of the notched portion of the front side wall 11 of the container body 10. Thus, the rear end portion 35 has a length that coincides with the rear end portions 13 a and 14 a of the left and right side walls 13 and 14 of the container body 10. Further, the thickness of the lid 30 is set so that the surface of the lid is positioned lower than the upper end surface of the side surface of the container body 10 in a state where the lid 30 is placed on the step portion 16 (see also FIG. 3).

蓋３０の後方端には第１の第２の垂下壁３６，３７が一体成形されている。第１の垂下部３６は、容器本体１０の後側壁１２に形成した第２の切り欠き１８の形状に一致した外形形状を持ち、蓋３０が前記最も奥まで入り込んだときに、第２の切り欠き１８内に入り込んでそこを閉鎖できる位置に形成されている。第２の垂下部３７は蓋３０の後方端部３５に沿って形成されており、前記のように蓋３０が最も奥まで入り込んだときに、容器本体１０の後側壁１２と左右の側壁１３，１４の後方端部１３ａ，１４ａとの間の空間内に入り込める形状とされている（図３も参照）。また、第２の垂下部３７の下端内側には凹所３８が形成されており、蓋３０の引き出しを容易にしている。   First and second hanging walls 36 and 37 are integrally formed at the rear end of the lid 30. The first drooping portion 36 has an outer shape that matches the shape of the second notch 18 formed in the rear side wall 12 of the container main body 10, and the second cutout 36 is formed when the lid 30 is fully inserted. It is formed at a position where it can enter the notch 18 and close it. The second drooping portion 37 is formed along the rear end portion 35 of the lid 30, and when the lid 30 is fully inserted as described above, the rear side wall 12 and the left and right side walls 13, 14 has a shape that can enter the space between the rear end portions 13a and 14a (see also FIG. 3).

The second protrusions 45, 45 are close to the left and right side edges 31, 32 on the first drooping portion 36 side, that is, on the front side in the lid pulling direction from the position where the cold air guiding protrusion 40 is formed. Provided.

保冷容器として使用するに当たっては、蓋３０を取り外した状態で容器本体１０の物品収容空間内に保冷しようとする物品Ｂ（図３，図５では菜の花の束を例として示している）を収容し、その上から蓋をする。上記の構成であり、蓋３０の側縁に形成した張出部３３を容器本体１０の側面部分に形成した縦方向の凹陥部１９に一致するようにして、蓋３０を上から落とし込むことにより、蓋３０はその両側縁近傍を容器本体１０の段差部１６に載せた状態で安定する。そして、蓋３０を前後方向にスライドさせることにより、蓋３０の張出部３３が容器本体１０側の凸片２０の下に入り込んで互いに係合した状態となり、容器本体１０と蓋３０は一体化する。   When used as a cold storage container, the article B (a bundle of rapeseed is shown as an example in FIGS. 3 and 5) is stored in the article storage space of the container body 10 with the lid 30 removed. Cover from above. By dropping the lid 30 from above so that the overhanging portion 33 formed on the side edge of the lid 30 coincides with the vertical concave portion 19 formed on the side surface portion of the container body 10 in the above configuration. The lid 30 is stable in a state where the vicinity of both side edges is placed on the stepped portion 16 of the container body 10. Then, by sliding the lid 30 in the front-rear direction, the overhang portion 33 of the lid 30 enters under the convex piece 20 on the container body 10 side and engages with each other, and the container body 10 and the lid 30 are integrated. To do.

蓋３０をスライドして最も奥（前方）まで押し込む。図２，図３に示すように、蓋３０の前方端３４が容器本体１０の前側壁１１の側面部分２２に衝接することにより、前方端側は閉鎖される。同時に、第１の垂下部３６が容器本体１０の後側壁１２に形成した第２の切り欠き１８に入り込むことにより、後端側も閉鎖される。それにより、物品収容空間は外気から遮断された状態となる。その状態で、保冷倉庫のような冷気雰囲気内に保冷容器Ａを搬入する。図２，図３に示すように、スペース効率を考慮して通常は多段に段積みされて冷気雰囲気下に置かれる。このような段積み作業は、容器本体１０に形成した凹所２１および蓋３０に形成した凹所３８を利用して容易に行うことができる。   Slide the lid 30 and push it all the way back (front). As shown in FIGS. 2 and 3, the front end side of the lid 30 is brought into contact with the side surface portion 22 of the front side wall 11 of the container body 10, whereby the front end side is closed. At the same time, the first drooping portion 36 enters the second notch 18 formed in the rear side wall 12 of the container body 10, so that the rear end side is also closed. As a result, the article storage space is blocked from the outside air. In this state, the cold insulation container A is carried into a cold air atmosphere such as a cold storage warehouse. As shown in FIG. 2 and FIG. 3, in consideration of space efficiency, they are usually stacked in multiple stages and placed in a cold atmosphere. Such a stacking operation can be easily performed using the recess 21 formed in the container body 10 and the recess 38 formed in the lid 30.

冷気雰囲気下において、蓋３０の一部を引き出す。作業者は蓋３０の第２の垂下部３７に形成した凹所３８に手を掛けて出すことにより、段積みされた複数の保冷容器Ａの任意のものを任意に選択して蓋３０の引き出しを行うことができる。一定距離だけ引き出すと、第２の突起４５，４５が容器本体１０の後側壁１２の内面に衝接し、それ以上の引き出しはできなくなる。その状態が図４，図５に示される。この状態では、蓋３０の第１の垂下部３６は容器本体１０の第２の切り欠き１８から離れるので、第２の切り欠き１８は開放されて第１の連通部となる。また、蓋３０の前方端３４も容器本体１０の前側壁１１から離れるので、その間は開放される。そして、段積みしたときに下段となる保冷容器Ａにおいても、その前側壁１１に形成した第１の切り欠き１７は閉鎖されることはないので、すべての保冷容器での前記開放部は第２の連通部として機能する。   A part of the lid 30 is pulled out in a cold atmosphere. The operator puts his hand in the recess 38 formed in the second drooping portion 37 of the lid 30, and arbitrarily selects any one of the plurality of stacked cold storage containers A to pull out the lid 30. It can be performed. When it is pulled out by a certain distance, the second protrusions 45, 45 abut against the inner surface of the rear side wall 12 of the container body 10, and further pulling out is impossible. The state is shown in FIGS. In this state, the first drooping portion 36 of the lid 30 is separated from the second notch 18 of the container body 10, so that the second notch 18 is opened and becomes the first communicating portion. Moreover, since the front end 34 of the lid | cover 30 also leaves | separates from the front side wall 11 of the container main body 10, it is open | released in the meantime. And also in the cold storage container A which becomes a lower stage when stacked, the first notch 17 formed in the front side wall 11 is not closed, so that the open portion in all the cold storage containers is the second. It functions as a communication part.

従って、保冷倉庫のような冷気雰囲気内において、保冷容器Ａの第２の連通部側を吸引ファンのような適宜の吸引側に接続すると、冷気は第１の連通部から容器収容空間内に流入し、第２の連通部から引き出される。その際に、本発明による保冷容器Ａは蓋３０の裏面に冷気案内用突起４０を備えているので、冷気は物品収容空間内を底面側に向けて強制的に案内される。そのために、図５に示すように、密な状態で菜の花Ｂが収容されている場合でも、全体がほぼ均一に冷却される。また、容器本体１０の内周面には冷気を案内するための凹溝１５が多数形成されており、それによっても、冷気は側面および底面から収容物品同士の隙間に入り込むことができ、一層均一な冷却が可能となる。   Accordingly, when the second communicating portion side of the cold container A is connected to an appropriate suction side such as a suction fan in a cold air atmosphere such as a cold storage warehouse, the cold air flows into the container housing space from the first communicating portion. Then, it is pulled out from the second communication part. At this time, the cold insulation container A according to the present invention includes the cold air guiding projection 40 on the back surface of the lid 30, so that the cold air is forcibly guided toward the bottom surface in the article housing space. Therefore, as shown in FIG. 5, even when rape blossom B is accommodated in a dense state, the whole is cooled almost uniformly. In addition, a large number of concave grooves 15 for guiding cool air are formed on the inner peripheral surface of the container body 10, so that the cool air can enter the gaps between the stored articles from the side surface and the bottom surface. Cooling becomes possible.

所要に収容物品が冷却された時点で、作業者は蓋３０を奥まで押し込んで、再び保冷容器の物品収容空間を外気から遮断する。その状態で、保冷倉庫から取り出し物流に供する。そのような過程で、保冷容器Ａは多くの作業者により種々の取り扱いを受けることとなるが、本発明による保冷容器においては、蓋３０を閉じた状態で、蓋３０の張出部３３を容器本体１０に形成した凸片２０の下に入り込ませて互いに係合した状態とすることができるので、蓋３０の閉鎖状態はきわめて安定したものとなり、蓋３０が不用意に容器本体１０から分離するようなことは確実に回避される。   When the stored article is cooled as necessary, the operator pushes the lid 30 all the way back, and again blocks the article storage space of the cold storage container from the outside air. In this state, it is taken out from the cold storage warehouse and used for logistics. In such a process, the cold insulation container A is subjected to various handling by many workers. In the cold insulation container according to the present invention, the overhanging portion 33 of the lid 30 is placed in the container with the lid 30 closed. Since it can enter under the convex piece 20 formed in the main body 10 and can be in a mutually engaged state, the closed state of the lid 30 becomes extremely stable, and the lid 30 is carelessly separated from the container main body 10. This is definitely avoided.

図６は上記の保冷容器Ａを複数個用いて差圧式保冷装置Ｃとする場合に一例を示している。この例では、３段に積み上げられた保冷容器群が、左右に３列ずつ、間にスペースＳを置いて、前記した第２の連通部側、すなわち、前側壁１１側を互いに対向する姿勢で配置されている。そして、前記スペースＳを外気から遮断するようにして通気性のないマット５０が掛けられており、かつ、遮断されたスペースＳは適宜の管路５１を介して図示しない吸引ファンに連通している。この状態の差圧式保冷装置Ｃが図示しない保冷倉庫内に置かれることにより、差圧式保冷装置Ｃは全体が冷気雰囲気下に曝されることとなる。   FIG. 6 shows an example in the case where a differential pressure type cold insulation apparatus C is formed by using a plurality of the cold insulation containers A described above. In this example, the cold storage container groups stacked in three stages are arranged in three rows on the left and right sides, with a space S between them, with the above-described second communication portion side, that is, the front side wall 11 side facing each other. Is arranged. A non-breathable mat 50 is hung so as to block the space S from the outside air, and the blocked space S communicates with a suction fan (not shown) via an appropriate pipe line 51. . By placing the differential pressure type cold insulation device C in this state in a cold storage warehouse (not shown), the differential pressure type cold insulation device C is entirely exposed to a cold atmosphere.

図６は、上記図４，図５に基づき説明した蓋３０の一部が引き出された状態となった保冷容器を示しており、この状態で吸引ファンを稼働すると、冷気は前記第１の連通部からすべての保冷容器Ａ内に等しく流入して、収容物品を等しく冷却する。冷却後の冷気は等しくスペースＳ内に引き出され、管路５１から外部へあるいは再冷却のために適宜の空調装置へ案内される。本発明の保冷容器Ａは、蓋の開度を一定にする目的で、蓋３０にストッパーとして機能する第２の突起４５を備えているので、図示のように多数の保冷容器Ａを１つのセットとして取り扱っても、保冷容器によって冷却ムラが生じることを容易にかつ確実に阻止することができる。   FIG. 6 shows the cold insulation container in which a part of the lid 30 described with reference to FIGS. 4 and 5 is pulled out, and when the suction fan is operated in this state, the cold air is communicated with the first communication. It flows equally into all the cold containers A from the section to cool the contained articles equally. The cooled air is equally drawn into the space S and guided from the pipe 51 to the outside or to an appropriate air conditioner for recooling. The cold insulation container A of the present invention includes the second protrusion 45 functioning as a stopper on the lid 30 for the purpose of making the opening degree of the lid constant. Can be easily and reliably prevented from causing uneven cooling due to the cold container.
