Radiant heat-absorbing heat-preserving container

Abstract

A radiant heat-absorbing heat-preserving container includes a heat-absorbing body having an outer surface, an opening, and a receiving space; and a light-permeable layer covering the outer surface of the heat-absorbing body. Another radiant heat-absorbing heat-preserving container includes a base, a heat-absorbing cover having an outer surface, and a light-permeable layer covering the outer surface of the heat-absorbing cover, wherein the heat-absorbing cover is tightly connected with the periphery of the base to form a receiving space between the heat-absorbing cover and the base. A thermal insulation layer is formed between the light-permeable layer and the heat-absorbing cover in the radiant heat-absorbing heat-preserving containers of the present invention. When the outer surface of the heat-absorbing body or cover is exposed to light passing through the light-permeable layer, the heat-absorbing body or cover absorbs the thermal energy of, and is thus heated by, the light. The thermal insulation layer prevents heat dissipation from the heat-absorbing body or cover.
