< Topic >The heat storage die yu which it tries to be able to detect the fluid leak easily in the heat storage die bedpan which utilizes the latent heat heat storage material, is the po is offered.SolutionsWith the heat storage die bedpan which encloses the heat storage material inside the container of the bag-like object, the latent heat heat storage material is used for heat storage material 3, at least the bag-like object is made duplex. Because of this, the latent heat heat storage material solidifying, as the inside material 21 catches the projection of the solid section and outer part material 22 eases the bombardment from outside, on that the heat storage material neutron leakage when breaking, with the inside material as opaque, in order to dye, it constitutes. Furthermore, it becomes easy to visualize, neutron leakage with damage only of the internal material, verification at the point in time when 3a is generated with easy by designating the outer part material as the transparent translucent material.< Choice figure >Drawing 2【課題】潜熱蓄熱材を利用した蓄熱型湯たんぽにおいて、液漏れを容易に検知できる様にした蓄熱型ゆたんぽを提供する。【解決手段】袋状体の容器の内部に蓄熱材を封入した蓄熱型湯たんぽで、蓄熱材3に潜熱蓄熱材を使用し、少なくとも袋状体を二重にする。これにより、潜熱蓄熱材が固形化しても、内側素材21が固形部の突起を受け止め外側素材22が外部からの衝撃を緩和すると共に、内側素材を不透明にして、その上に破損時に蓄熱材が漏れ染まるように構成する。さらに、外側材を透明半透明材とすることにより、目視しやすく、内部素材のみの破損で漏れ3aが発生した時点での確認が容易となる。【選択図】図2
