Abstract
Description
そのため、こうした商品、製品の温度管理は生産時のみならず、流通時、保管時において厳格に温度管理を行なう必要があり、その温度管理を継続的に監視していく手段のひとつとして、感温インジケータが用いられている。
さらに、上述した凸型形状部でラベルコンプの引き抜き時に破壊できなかったカプセルも該屈曲部をラベルコンプが通過することでカプセルを確実に破壊することが可能で、より確実に破壊できるという利点もある。
この吸収紙23は平面視ほぼ細帯状の形状に形成され、その一端側にカプセル28を保持および保護する凸状部が位置し、また吸収紙23の他端がカバー材24の端部よりも外部に露呈することにより、感温表示部となっている。
これを説明すると、二枚の板状部材である下ベース材12と上ベース材11とを備える。これらの上、下ベース材11,12は、図1~図3に示すように、下ベース材12の一部に凸型形状部16を有し、これに上ベース材11を組み合わせることにより、内部にほぼ凸型形状を呈する空間を形成するようにしている。そして、この空間内に前記ラベルコンプ21のカプセル28を収容した凸部(凸部形成部27)を収納して保持および保護した状態でラベルコンプ21を挟み込むように構成されている。
このような屈曲部31,32は、基材ベースの剛性を向上させるとともに、引き抜き操作によって、狭い隙間を通過することで、カプセル28を確実に潰して破壊するための部分である。
そして、使用時には、基材ベース13から使用する1枚を引き抜き、被測定物を保管する、例えば保冷庫等に同封させて添付する。なお、?離紙26等を?離することで、製品、商品に貼り付けてもよい。
この場合、カプセル28が潰れるだけでは発色せず、その後、被測定物に添付されることで、温度を監視する。
一方、発色していれば、配送時などに温度上昇などの問題が生じたことを確認することができる。したがって、例えば、生鮮食品、切り花等の生鮮物、医薬品、半導体材料等において、温度管理が十分に行われず、所定の温度以上に晒されると品質が劣化する商品、製品に用いて好適である。
また、このようにラベルコンプ21を併設して設ける構造では、基材ベース13が大型化することで、ラベルを引き抜く際に手で保持し易く、さらに廃棄する際にも廃材の削減が可能である等の利点もある。
例えば、上述した実施形態では、複数枚(5枚)のラベルコンプ21を、上、下ベース材11,12間に挟み込んだ状態で、基材ベース13の一側に沿って並列して保持させた構造である場合を説明したが、本発明はこれに限定されず、基材ベースの両側にそれぞれ複数枚のラベルコンプを並列して配列し、ラベルコンプを基材ベースから引き抜いて使用することができるように構成する等の種々の変形例が考えられる。
さらに、屈曲部31,32としても、上述した実施形態のように幅狭の屈曲通路を形成した場合に限らず、上、下ベース材11,12のいずれか一方を屈曲させ、他方を平坦のままで形成した屈曲空間で構成してもよい。
また、上、下ベース材11,12の端部を折り曲げ形成することにより、該ベース材11,12の剛性をアップさせるように構成する等の変形例も考えられる。
