Description
図1は本発明にかかる熱履歴変化型インジケーター1の概略図である。本発明にかかる熱履歴変化型インジケーター1は、大別すると基材10と、熱可融性物質を含む熱可融性物質層20と、熱可融性物質が浸透すると透明または半透明となる片面に彩色が施された浸透層30と、融解した熱可融性物質が浸透層30の彩色面側から浸透するのを阻害するための熱可融性物質浸透阻害層40と、表面全体を覆う保護層50と、から構成される。そして、図1のように、熱可融性物質層20と、熱可融性物質浸透阻害層40と、浸透層30とはこの順に積層され、基材10と保護層50で挟み込まれた積層構造となっている。
基材10は、被着体の構成による。熱履歴変化型インジケーターの最下層に位置するものであって、後述する保護層50と共に、熱可融性物質層20と、熱可融性物質浸透阻害層40と、浸透層30とを被覆するためのものである。基材10は、アルミ箔またはプラスチック基材が好ましく、ラベル形態であれば片面に粘着層を兼ね備えていることが好ましい。粘着層を設けることで、即席カップ麺の容器や蓋に貼付できる。
熱可融性物質層20は、基材10と後述する浸透層30との間に載置されるものであって、浸透層30を半透明または透明にするための熱可融性物質を含有している。含有している熱可融性物質量は、浸透層30を透明または半透明にするのに必要な量を含有していればよく、特に制限されない。
本発明に係る浸透層30は、融解した熱可融性物質が浸透することによって透明または半透明化するものである。
熱可融性物質浸透阻害層40は、熱可融性物質層20と浸透層30との間に設けられる層であって、融解した熱可融性物質が浸透層30の彩色面側から浸透するのを防ぐためのものである。熱可融性物質浸透阻害層40は、浸透層30の彩色を施した面全てを被覆していることが好ましい。これにより、融解した熱可融性物質が浸透層30の端面から徐々に浸み込むよう誘導できる。
本発明に係る保護層50は、熱履歴変化型インジケーター1の最上層に位置し、基材10と共に熱可融性物質層20と、浸透層30と、熱可融性物質浸透阻害層40と、を被覆し密閉するためのものである。これにより、熱可融性物質層20と、浸透層30と、熱可融性物質浸透阻害層40と、が位置ズレすることを防ぐ。また、湿気や水など外部からの侵入によって浸透層30が半透明または透明になってしまうことを防ぐ。さらに、融解した熱可融性物質がインジケーターの外へ浸み出さずに、保護層50を伝って、浸透層30の端面に到達することができる。
例えば、上記実施例では浸透層30の片面に彩色を施したものについて説明したが、有色の紙(色紙)の上に浸透層を積層した構造としてもよい。この時、色紙に熱可融性物質が含浸しないように、色紙全体を熱可融性物質浸透阻害層によって被覆していることが好ましい。また、色紙にコーティング層を設けてもよい。かかる場合、コーティング層が熱可融性物質浸透阻害層の役割を果たす。さらに、色紙を用いる場合には、熱可融性物質層と色紙の間、または、色紙と浸透層との間の少なくともいずれかに熱可融性物質浸透阻害層を設ければよい。このような場合においても本発明の効果を奏する。
