ABSTRACT:
A delivering equipment with heat insulating function according to the present invention is utilized in delivering food and so on and comprises an insulated receptacle made of insulating material for storage of food and the like, a concave formed in the bottom portion within the receptacle for storage of regenerating means, and regenerating means disposed in the concave. The regenerating means is preferably comprised of a transparent case packed with regenerating material which contains higher fatty acid as a main content. The regenerating material may be of 100% of behenic acid and preferably contain 10% of cured castor oil so as to depress the solidification point of the regenerating material. Further, a delivering equipment with heat insulating function according to the present invention comprises an insulating receptacle for storage of food and so on and a heat panel with heat pipes disposed within the receptacle so as to equalize the temperature distribution in the receptacle. In case of a delivering equipment with keeping warm function heat source of the heat pipes is regenerating means for heating disposed in the concave which is formed in the bottom portion within the receptacle.
Whereas, in case of a equipment with keeping cold function, heat source of the heat pipes is regenerating means for cooling disposed in the concave which is formed in the upper portion within the receptacle.
