PROBLEM TO BE SOLVED: To provide a warmer suppressing a production cost, and retaining a melting state for a long time while retaining the qualities of chocolate and an animal and vegetable oil and fat product.SOLUTION: This warmer is used for a storage container set with an oil and fat product storing part with a bottom wall, and an insertion space divided from the oil and fat product storing part through the bottom wall, and arranged under the bottom wall, and retains an oil and fat product stored in the oil and fat product storing part in a melting state. Furthermore, the warmer includes an insertion part free to insert and extract into/from the insertion space, and the insertion part has an upper surface part opposed to the bottom wall of the product storing part, and is formed in a box-like form expanding to the surface direction of the bottom wall. The insertion part is attached with a heating part in the inside, and the upper surface part is formed so as to disperse heat conducted from the heating part to the surface direction.COPYRIGHT: (C)2012,JPO&INPIT【課題】 製品コストを抑えるとともに、チョコレートおよび動植物性油脂製品の品質を維持したまま、しかも融解状態を長時間にわたって維持し得る保温装置の提供を目的とする。【解決手段】 底壁を備えた油脂製品収容部と該油脂製品収容部とは底壁を介して区画され前記底壁の下側に配置された挿入空間とを設けた収容容器に用いられ、前記油脂製品収容部に収容された油脂製品を融解状態で維持するための保温装置であって、前記挿入空間に挿抜自在とされる挿入部を備え、該挿入部は、その上面部が前記製品収容部の底壁に対向するとともに底壁の面方向に広がる箱状に形成され、該挿入部は内部に加熱部が装着されるとともに、前記上面部は前記加熱部から伝えられた熱が面方向に分散されるよう構成されている保温装置。【選択図】 図1
