Abstract

La présente invention concerne, selon un mode de réalisation, une technologie pour déplacer facilement une partie de vapeur d'eau par un corps de génération de chaleur et de l'eau à partir d'un contenant externe, dans lequel le corps de génération de chaleur est positionné, jusqu'à un contenant interne dans lequel de la nourriture et une boisson sont positionnées. Selon un mode de réalisation de la présente invention, un contenant alimentaire de génération de chaleur apte à fournir facilement de la vapeur d'eau dans un contenant interne comprend : un contenant externe qui reçoit un corps de génération de chaleur pour générer de la chaleur par réaction avec de l'eau, et comporte une partie d'extension de contenant externe s'étendant vers l'extérieur à une portion d'un coin de celui-ci et un passage d'entrée formé à l'intérieur de la partie d'extension de contenant externe pour permettre à de l'eau d'être introduite dans celui-ci ; un contenant interne qui reçoit de la nourriture et une boisson à l'intérieur de celui-ci, est formé sous une forme correspondant au contenant externe, est reçu dans le contenant externe, est supporté par le contenant externe, et comporte une partie d'extension de contenant interne accouplée à la partie d'extension de contenant externe de façon à fermer le passage d'entrée ; et un couvercle accouplé à la partie supérieure du contenant interne de façon à sceller l'intérieur du contenant interne.
