Abstract

Un mode de réalisation de la présente invention concerne un récipient pour aliments qui utilise un élément chauffant, le récipient ayant une structure améliorée pour faciliter l'injection d'eau en vue de chauffer un élément chauffant, sans transférer, vers un récipient séparé, des aliments chauffés au moyen d'une chaleur de réaction avec l'eau, et permettre une réaction exothermique continue avec l'eau tout en maintenant de manière stable l'élément chauffant à l'intérieur du récipient. Un récipient de chauffage d'aliments ayant une fonction d'élimination de poussière, selon un mode de réalisation de la présente invention, comprend : un récipient externe qui accueille un élément chauffant qui réagit avec l'eau pour générer de la chaleur, et qui possède une première partie étendue qui s'étend vers l'extérieur à partir d'un coin de celui-ci, un passage d'écoulement entrant formé à l'intérieur de la première partie étendue de sorte que l'eau s'écoule à l'intérieur de celle-ci, et une nervure de couplage faisant saillie vers le haut le long du bord de son côté supérieur ; un récipient interne, à l'intérieur duquel sont accueillis des aliments, est réalisé dans une forme correspondant au récipient externe de façon à être couplé au côté supérieur du récipient externe, et possède, au niveau d'un coin de celui-ci, une deuxième partie étendue destinée à être couplée à la première partie étendue du récipient externe, fermant ainsi le passage d'écoulement entrant, et possède une rainure de montage, dans laquelle doit venir s'ajuster et s'accoupler la nervure d'accouplement, le long du bord du côté supérieur de celui-ci de façon à être ajusté dans le récipient extérieur et accouplé à celui-ci ; et un couvercle destiné à être accouplé à la portion supérieure du récipient interne.
