Description

定温容器
　本発明は、定温容器に関する。
　従来、収納物を一定時間、一定の温度域で維持する容器として、定温容器が用いられる。そして、定温容器には、断熱性を向上させるべく、真空断熱材が用いられる。真空断熱材は、アルミニウム層を蒸着やラミネートで形成した外被材により、芯材を減圧密封して作られたものが用いられている。（例えば、特許文献１参照）。また、定温容器内には、保冷剤として水とゲル化剤で造られる水系蓄冷剤が用いられている。
　また、温度管理が必要な収納物において、輸送状態を把握ために温度センサ等が輸送品に同梱され、温度など輸送環境情報を認識可能とすることもある。
特開２００８－０３０７９０号公報
　収納物が、例えば、治験薬の場合、特定の温度域（例えば、２℃～８℃）に維持することが要求されており、併せて、輸送状態で治験薬の温度など輸送環境情報が認識され、治験薬が輸送過程において適正管理されることが要求されている。
　しかしながら、真空断熱材の外被材に含まれるアルミ層が電波を反射するため、真空断熱材を通信用の電波が透過し難くなる。このため、真空断熱材で覆われる定温容器内より電波を用いて、定温容器内の温度などの情報を定温容器外に送信することは困難である。
　本発明は、前記した事情に鑑みてなされたものであり、定温容器の通信用電波の透過性と保冷性能の向上を両立させた定温容器を提供することを目的とする。
　前記目的を達成するため、本発明は、断熱容器と、前記断熱容器を閉塞する断熱蓋体と、前記断熱容器の内部に収容される箱本体と、前記箱本体を閉塞する箱蓋体と、前記箱本体の底部と壁部と前記箱蓋体とに設けられた相変化材料と、を備え、前記箱本体の内側から前記断熱容器の外側に至る経路に、電波透過性の有機物で構成される箇所を設けたことを特徴とする。
　これによれば、電波透過性の有機物のみで構成される部分を介して、収納空間内から定温容器外に電波が透過しやすくなる。これにより、収納空間内から定温容器の外に電波を送信しやすくなる。
　なお、この明細書には、２０１９年６月１７日に出願された日本国特許出願・特願２０１９－１１２２４３号の全ての内容が含まれるものとする。
　本発明によれば、収納空間内に通信機器を配置して、定温容器が閉じられた状態で、収納空間内の情報を定温容器の外から読み取りやすくなる。
図１は、本発明の実施形態に係る定温容器の分解斜視図 図２は、定温容器の長手方向における縦断面図 図３は、本体容器の斜視図 図４は、収納箱と固定体との分解斜視図
　第１の発明は、断熱容器と、前記断熱容器を閉塞する断熱蓋体と、前記断熱容器の内部に収容される箱本体と、前記箱本体を閉塞する箱蓋体と、前記箱本体の底部と壁部と前記箱蓋体とに設けられた相変化材料と、を備え、前記箱本体の内側から前記断熱容器の外側に至る経路に、電波透過性の有機物で構成される箇所を設けたことである。
　これによれば、電波透過性の有機物のみで構成される部分を介して、収納空間内から定温容器外に電波が透過しやすくなるので、収納空間内から定温容器の外に電波を送信しやすくなる。
　第２の発明は、前記相変化材料は、パラフィンを主成分とする。
　これによれば、ＵＨＦ帯（極超短波）およびＳＨＦ帯（センチメートル波）の電波が相変化材料により減衰される程度を、水に比べて非常に小さくすることができる。これにより、携帯電話用の通信回線やＲＦＩＤ（ｒａｄｉｏ　ｆｒｅｑｕｅｎｃｙ　ｉｄｅｎｔｉｆｉｃａｔｉｏｎ）を用いて、収納空間内から定温容器の外に情報を送信できる。
　第３の発明は、前記相変化材料は、樹脂の外被で覆われており、前記外被の周縁を折り曲げたものである。
　これによれば、相変化材料を密に配置しながら、相変化材料による電波の減衰を低減することができる。
　第４の発明は、前記箱本体の内側から前記断熱容器の外側に至る前記経路以外の部分に金属を含むものである。
　これによれば、収納箱の遮熱性を向上できるとともに、電波による収納空間Ｖ内と外での電波による通信を可能にする。
　以下、本発明の実施の形態について図面を参照して説明する。
　図１は、本発明の実施形態に係る定温容器１の分解斜視図である。図２は、定温容器１の長手方向における縦断面図である。
　図１および図２に示すように、定温容器１は、本体容器である真空断熱容器３と、本体蓋体である真空断熱蓋体４と、真空断熱容器３に収容される収納箱５とを備えている。定温容器１は、容器ケース２に収められて使用される。
　図３は、真空断熱容器３の斜視図である。
　真空断熱容器３は、外側外被材３４を備えている。
　外側外被材３４は、上面が開放された箱型に形成されており、外側外被材３４の内側には、この外側外被材３４の各側面および底面に対して所定間隙を有する寸法に形成された内側外被材３３が配置されている。外側外被材３４および内側外被材３３との間には、芯材３５が収容されている。
　そして、外側外被材３４および内側外被材３３との間に芯材３５を配置した状態で、外側外被材３４および内側外被材３３との間の外周縁が密封される。そして、外側外被材３４および内側外被材３３との間の空気を排出することで、芯材３５が減圧密封された真空断熱機能を備えた真空断熱容器３が形成される。
　外側外被材３４および内側外被材３３は、特に限定するものではないが、ガスバリア性に優れた樹脂材料で成型されており、例えば、ポリプロピレンやエチレンビニルアルコール共重合体等の成型可能な樹脂が用いられる。
　芯材３５は、特に限定するものではない。芯材３５は、例えば、ポリオールやイソシアネートからなり連続気泡構造を有するウレタンフォームや、ガラス繊維からなる成型体、ヒュームドシリカからなる成型体など、真空断熱材の芯材として利用される材料を用いることができる。
　真空断熱容器３の内部には、図３に示すように、収納空間Ｓが設けられている。
　外側外被材３４の底部と芯材３５との間には、気体吸着剤３６と、水分吸着剤３７と、中央に孔を有する補強板３８が配置されている。真空断熱容器３は、各側面に比較して底面からの熱放出が少ないことから、真空断熱容器３の底面に気体吸着剤３６、水分吸着剤３７、補強板３８を配置しても、断熱効果に支障はない。
　外側外被材３４の補強板３８の孔に対応する位置には、真空断熱容器３内の空気を真空引きするための排気孔が設けられており、この排気孔は、真空断熱容器３の内部を真空引きした後に、図示しない封止材により封止される。なお、補強板３８を設けているので、真空引きする際や、封止材により排気口を封止する際に、排気口まわりの変形を抑え、封止材を支持することができる。
　本体保護ケース３２は、真空断熱容器３の外表面を覆う筐体である。本体保護ケース３２は、例えば発泡スチロールといった断熱性を有する樹脂で形成されてもよい。また、衝撃吸収性のある樹脂により形成することで、真空断熱容器３への衝撃が低減される。
　真空断熱蓋体４は、真空断熱容器３の開口部を閉塞する部材である。
　図２に示すように、真空断熱蓋体４は、本体保護ケース３２の外形と同様の外形を有する蓋体外側保護ケース４２を備えている。蓋体外側保護ケース４２の下面周縁部には、下方に向けて延在する上部接合部４７が蓋体外側保護ケース４２の周囲全体に亘って形成されている。上部接合部４７は、の下面には、接合凹部４６が形成されている。
　蓋体外側保護ケース４２の下面には、上部接合部４７により囲まれた凹状の外側収容部４２Ａが形成されている。
　蓋体外側保護ケース４２の下方には、蓋体内側保護ケース４３が配置されている。蓋体内側保護ケース４３の上面周縁部には、上方に向けて延在する下部接合部４８が蓋体内側保護ケース４３の周囲全体に亘って形成されている。下部接合部４８の上面には、接合突起４９が形成されている。
　蓋体内側保護ケース４３の上面には、下部接合部４８により囲まれた凹状の内側収容部４３Ａが形成されている。
　そして、蓋体外側保護ケース４２と蓋体内側保護ケース４３とは、上部接合部４７の接合凹部４６と下部接合部４８の接合突起４９とを互いに接合させることで一体に形成される。この状態で、蓋体外側保護ケース４２の外側収容部４２Ａと、蓋体内側保護ケース４３の内側収容部４３Ａとにより、所定の内部空間Ｉが形成される。
　この内部空間Ｉには、真空断熱板４１が収容されている。真空断熱板４１の四隅には、略Ｌ字状の固定部材４４が取り付けられている。そして、真空断熱板４１を内部空間Ｉに収容した状態で、固定部材４４が内部空間Ｉの四隅に当接することで、真空断熱板４１を内部空間Ｉの内部で動かないように固定することが可能となる。
　なお、真空断熱板４１は、略Ｌ字状の固定部材４４に限らず、例えば、真空断熱板４１の各辺に沿って設けられた直線状の固定部材や、接着剤等を用いて蓋体外側保護ケース４２、及び蓋体内側保護ケース４３に固定してもよい。
　なお、本実施の形態においては、真空断熱板４１は、真空断熱容器３と同一の材料で形成されているが、真空断熱板４１として、例えば、ガスバリア性のある樹脂フィルムにより、芯材を封入した真空断熱材を用いるようにしてもよい。
　また、本実施の形態においては、蓋体外側保護ケース４２および蓋体内側保護ケース４３は、本体保護ケース３２と同一の材料で形成されている。
　蓋体内側保護ケース４３の下面外周近傍には、下方に突出する凸状部４５が形成されている。凸状部４５は、真空断熱蓋体４を真空断熱容器３に装着して、真空断熱容器３の上面を閉塞した状態で、その外側面が真空断熱容器３の内側面に当接するように構成されている。このように、凸状部４５を設けることで、真空断熱容器３と真空断熱蓋体４との間における熱侵入経路を長く設定することができ、定温容器１の断熱性能を向上することが可能となる。
　図４は、収納箱５と支持部材６との分解斜視図である。なお、図４では、ロガーケース５９を省略して示している。
　真空断熱容器３の収納空間Ｓには、収納箱５が着脱可能に収容されており、収納箱５は、図４に示すように、箱本体５１と、箱蓋体５２とを備えている。
　箱本体５１は、上面が開放された箱型の外箱５３を備えている。外箱５３は、長方形の底板５３Ａ、この底板５３Ａの四辺から立設される４枚の側板５３Ｂを備えている。各側板５３Ｂの上端縁には、外箱５３の内側に向かって所定の幅寸法で延在する上板５３Ｃが形成されており、各上板５３Ｃの内側縁には、下方に延在する折り返し板５３Ｄが一体に形成されている。折り返し板５３Ｄは、各側板５３Ｂの途中に相当する位置まで形成されている。
　外箱５３の内側には、上面が開放された箱型の内箱５４が収容されている。内箱５４は折り返し板５３Ｄの内面に当接するように形成されている。
　外箱５３と、内箱５４とは、いずれも可塑性を有する薄板状樹脂材料を折り曲げることで箱型に成型されている。樹脂材料としては、例えば、透明なポリプロピレンやＡＢＳ樹脂などが用いられる。
　外箱５３の各側板５３Ｂと折り返し板５３Ｄとの間、および底板５３Ａの上面には、それぞれ平板状の蓄冷剤５７が収容されている。底板５３Ａに配置される蓄冷剤５７は、底板５３Ａのほぼ全面に亘って配置されており、側板５３Ｂに配置される蓄冷剤５７の下端は、底板５３Ａに配置される蓄冷剤５７に接触している。
　また、蓄冷剤５７は、外被５７Ａの周縁を折り曲げた状態で、箱本体５１および箱蓋体５２に収納される。外被５７Ａは、隣接する蓄冷剤５７間に位置しないように折り曲げられる。これにより、蓄冷剤５７間を密にできる。
　すなわち、箱本体５１の底部と壁部とには、互いに熱的に隙間なく蓄冷剤５７が配置されている。これによって、収納箱５の外部からの伝熱を抑制し、収納箱５の内部を所定温度域内に維持することができる。
　また、各折り返し板５３Ｄは、各側板５３Ｂの途中に相当する位置まで形成されているため、各側板５３Ｂと折り返し板５３Ｄとの間に蓄冷剤５７を収容することが容易である。
　そして、蓄冷剤５７を収容した後、外箱５３の内側に内箱５４を収納することにより、各蓄冷剤５７は、外箱５３と内箱５４との間に保持される。これによって、板状の各蓄冷剤５７を確実に支持固定することができ、定温容器１の運搬時においても各蓄冷剤５７同士が離間することを抑制できる。
　箱本体５１の内部、すなわち内箱５４の内部には、収納空間Ｖが設けられている。
　箱蓋体５２は、箱本体５１の開口部を閉塞して収納箱５の天面を構成する部材である。箱蓋体５２は、箱本体５１と同一の樹脂材料を折り曲げることで薄い箱型に形成されており、箱蓋体５２の外形は、箱本体５１の上部開口と略同一の形状となるように形成されている。
　箱蓋体５２の長手方向に位置する両側下縁には、下方に向かって延在する板状(フラップ状)の差し込み部５８がそれぞれ形成されている。差し込み部５８は、箱蓋体５２の幅寸法と同一の幅寸法となるように形成されている。
　そして、箱蓋体５２により箱本体５１の上部開口を閉塞する場合には、各差し込み部５８を各折り返し板５３Ｄと、内箱５４との間に差し込むことで、箱蓋体５２を固定するように構成されている。
　ここで、箱蓋体５２を箱本体５１の上部開口と略同一の形状に形成するとともに、差し込み部５８の幅寸法を箱蓋体５２の幅寸法と同一の幅寸法となるように形成している。このため、折り返し板５３Ｄと、内箱５４との間に差し込み部５８を差し込んだ状態で、差し込み部５８が箱本体５１の上部開口の幅に位置することになり、箱本体５１に対して箱蓋体５２を適正に位置決めすることが可能となる。
　箱蓋体５２の内部には、蓄冷剤５７が収容されている。
　蓄冷剤５７は、収納箱５の内部を、例えば、２～８℃程度の常温よりも低い温度に保つものである。本実施形態の蓄冷剤５７は、物質の相変化、相転移に伴う転移熱を利用することが可能な相変化材料５７Ｂを備え、このような転移熱を熱エネルギーとして蓄えて、潜熱蓄熱材として利用するものである。蓄冷剤５７は、相変化材料５７Ｂを樹脂の外皮５７Ａで覆うことで形成されている。
　蓄冷剤５７は、冷却されることにより、液体、またはゲルから固体へと相変化材料５７Ｂが相変化し、熱を吸収してその温度が上昇することにより、固体から液体、またはゲルへと相変化材料５７Ｂが相変化する。すなわち、蓄冷剤５７は、相変化材料５７Ｂが固体に相変化することで冷熱を蓄えた状態となって、熱を吸収することが可能となる。
　本実施形態の蓄冷剤５７には、相変化材料５７Ｂとして、各種パラフィンに添加物を適宜調合して、相転移が起きる凝固点、融解点を所定温度になるように調整したものが用いられている。
　このような相変化材料５７Ｂを用いることにより、ＵＨＦ帯およびＳＨＦ帯の電波の減衰を水に比べて非常に小さくすることができる。このため、携帯電話用の通信回線やＲＦＩＤを用いて、効率的に収納箱５内から定温容器１の外に情報を送信できる。
　収納箱５の内部における角部には、各種センサを備えたデータロガーを収容するロガーケース５９が設けられている。データロガーとしては、例えば、温度を計測可能なものを用いることができる。また、位置や、加速度を計測し、それらの情報を送信可能としたものを用いることができる。
　真空断熱容器３の収納空間Ｓの底部には支持部材６が収容されている。
　支持部材６は、略平板状に形成されており、支持部材６の上面には、収納箱５の外形と略同一の形状に形成された支持凹部６１が形成されている。
　支持部材６は、例えば、発泡スチロールなどの断熱材料から形成されている。
　収納箱５は、支持部材６の支持凹部６１に載置することで真空断熱容器３の内部に収容され、支持固定される。この状態で、収納箱５の外側面は、真空断熱容器３の内側面に対して所定の隙間Ｇ１を空けて配置される。同様に、箱蓋体５２は、真空断熱蓋体４の下面および凸状部４５との間に所定の隙間Ｇ２を空けて配置される。
　また、収納箱５の底板５３Ａと間隙凹部６２との間には、隙間Ｇ３が設けられる。さらに、間隙凹部６２には、複数の貫通孔６３が設けられている。
　定温容器１は、収納物を運搬するときに、定温容器１を持ち運びやすいように容器ケース２に収容される。この容器ケース２は、上面が開放された箱型のケース本体２２と、ケース本体２２の上部一側縁に連結されるケース蓋体２１とを備えている。
　ケース蓋体２１と、ケース本体２２とは、ケースファスナ２３によって閉じることが可能となっている。ケースファスナ２３は、ケースファスナ２３を開閉操作するための取手２４が設けられている。
　ケース本体２２の前面には、複数のケース蓋固定具２５が設けられている。これらのケース蓋固定具２５には、ケース蓋体２１の天面に設けられた複数の固定ベルトが連結され、これによって、容器ケース２、および定温容器１をより確実に閉塞状態に保持することが可能となっている。
　容器ケース２の各側面には、それぞれハンドル２６が設けられ、また、両側面に連結される運搬ベルト２７が設けられている。これらのハンドル２６、および運搬ベルト２７によって、容器ケース２、および定温容器１の運搬が容易となっている。
　容器ケース２の前面には、複数の書類収納部２８が設けられている。
　定温容器１の材質について、より詳しく説明する。
　真空断熱容器３の内側外被材３３、および外側外被材３４はガスバリア性のある樹脂で成形される。このような樹脂としては、前述のポリプロピレンの他に、ポリエチレンやエチレンビニルアルコール共重合体など真空中でガス放出の少ない樹脂を用いても良い。また、芯材としては、硬質ウレタンフォームの他に、グラスウール、ヒュームドシリカ粉末等真空断熱材の芯材として利用される材料、を用いても良い。
　真空断熱板４１と同様に、外被材にポリプロピレンの他に、ポリエチレンやエチレンビニルアルコール共重合体など真空中でガス放出の少ない樹脂を、用いても良い。また、芯材としては、硬質ウレタンフォームの他に、グラスウール、ヒュームドシリカ粉末等真空断熱材の芯材として利用される材料等、を用いても良い。
　このように、真空断熱容器３、および真空断熱板４１は、金属を用いることなく、芯材３５を減圧密封した断熱容器を構成している。これにより、定温容器１は有機物である樹脂製の部材により構成される。
　そして、本体保護ケース３２、蓋体外側保護ケース４２、および蓋体内側保護ケース４３も、前述のように樹脂により形成される。
　収納箱５も樹脂により形成され、蓄冷剤５７の相変化材料５７Ｂにもパラフィン系のものが用いられる。さらに、蓄冷剤５７の外皮５７Ａも、ポリエチレン、ＰＥＴ、ポリプロピレン等の樹脂が用いられる。
　また、運搬時に定温容器１を収納する容器ケース２を、化学繊維や天然繊維の布や、樹脂により形成してもよい。
　次に、本実施の形態の作用について説明する。
　定温容器１は各部に金属を含まず、樹脂により形成されるため、定温容器１を電波が透過可能となっている。そして、収納箱５の収納空間Ｖより、定温容器１外に電波を発信可能となる。
　なお、容器ケース２に収納された状態でも、電波が容器ケース２とともに定温容器１を透過可能となる。
　このように、定温容器１において、電波を透過させ難いアルミ箔などの金属部材で収納空間Ｖを覆うことなく、収納空間Ｖに対する断熱性を確保しながら、収納空間Ｖから定温容器１外へ電波を発信可能としている。
　収納箱５内のロガーケース５９にデータロガー等の通信装置を配置した場合、収納箱５内の通信装置と、定温容器１の外の通信装置とで、電波による通信が可能となる。例えば、収納箱５内のロガーケース５９内に、通信機能を備えた温度センサを配置して、輸送過程での収納箱５内の温度情報を定温容器１の外に配置される通信装置に送信することができる。
　これにより、収納箱５内に収納される物品の近傍で温度計測し、輸送過程における温度変化を常に認識することができる。特に、医薬品の輸送においては、輸送過程においても品質管理が可能となる。
　収納箱５内と、定温容器１の外との電波通信のためには、必ずしもすべての部材が、電波透過性の樹脂により構成される必要はなく、収納箱５内と定温容器１外とを結ぶ経路上に位置する部位が、樹脂のみで構成されれば良い。
　特に、送信機および受信機と、定温容器１との位置関係が決まっている場合には、樹脂のみで構成される部分を送信機と受信機との間に位置させることにより、効率的に電波による通信を行うことができる。
　なお、収納箱５内と定温容器１外とを結ぶ経路を所定の断面積の直線的な経路とすることにより、透過する電波が減衰され難くなる。また、電波が通る経路に含まれる部分は、電波が透過しやすい樹脂で構成され、その大きさは通信に使用される電波の強度や波長に応じて適宜決定される。
　すなわち、収納箱５内と定温容器１外とを結ぶ経路に、樹脂のみで構成される部分が配置されれば、その他の部分は、金属等の電波を透過しにくい材料で形成するようにしてもよい。
　例えば、真空断熱蓋体４に収容される真空断熱板４１として、アルミ層を有するフィルムで芯材を減圧密封した真空断熱材を用いてもよい。これにより、定温容器１において、上方よりの熱の影響を低減しながら、真空断熱容器３に電波を通すことができる。
　また、箱蓋体５２において、収納空間Ｖに向いていない面を、アルミ層を有するフィルムで芯材を減圧密封した真空断熱材で覆っても良い。これにより、収納空間Ｓの上部に暖かい空気が侵入した場合においても、箱蓋体５２に収納される蓄冷剤５７への影響を低減しながら、箱本体５１に電波を通すことができる。
　以上説明したように、本実施の形態においては、断熱容器である真空断熱容器３と、真空断熱容器３を閉塞する断熱蓋体である真空断熱蓋体４と、真空断熱蓋体４の内部に収容される箱本体５１と、箱本体５１を閉塞する箱蓋体５２と、箱本体５１の底部と壁部と箱蓋体５２とに設けられた相変化材料５７Ｂと、を備え、箱本体５１の内側から真空断熱容器３の外側に至る経路に、電波透過性の有機物で構成される箇所を設けた。
　これによれば、収納箱５の保冷保温性能および、真空断熱容器３および真空断熱蓋体４による断熱性能を確保しながら、収納箱５内との通信を可能とする。
　保冷もしくは保温した状態で、収納箱５内の状況を電波により、リアルタイムで確認可能となる。そして、輸送工程において、輸送物の管理を行うことができる。
　また、本実施の形態においては、相変化材料５７Ｂは、パラフィンを主成分とする。
　これによれば、パラフィンによるＵＨＦ帯およびＳＨＦ帯の電波の減衰は、水に比べて非常に小さく、ＵＨＦ帯およびＳＨＦ帯の電波を用いて収納箱５内から定温容器１外に効率的に情報を送信することができる。
　また、本実施の形態においては、相変化材料５７Ｂは、樹脂の外被で覆われており、外被の周縁を折り曲げたものである。
　これによれば、蓄冷剤５７間を密にでき、熱的に隙間なく蓄冷剤５７が配置される。そして、蓄冷剤５７による電波の減衰を低減できる。
　また、本実施の形態においては、箱本体５１の内側から真空断熱容器３の外側に至る経路以外の部分に金属を含む。
　これによれば、金属を含む部材を用いても、電波による収納空間Ｖ内と外での電波による通信を可能にする。また、金属を用いた断熱真空材を用いることにより、収納箱５の断熱性を向上される。
　なお、本実施の形態は本発明を適用した一態様を示すものであって、本発明は前記実施の形態に限定されない。
　例えば、本実施の形態では、潜熱蓄熱材として、蓄冷剤５７を用いて、保冷を行う場合の定温容器について説明したが、本発明はこれに限定されない。例えば、蓄冷剤５７に代えて、保温材を用いて、室温より暖かい温度域で、収納箱５内に物品を収納しても良い。
　以上のように、本発明に係る定温容器は、一定温度域で保冷保温され輸送時の品質管理を必要とする物品を収納する定温容器として好適に利用可能である。
