Abstract: A microwave overheating prevention container has at least an external surface in internal and external surfaces of a metallic container coated with a nonmetallic material which is a synthetic resin material. The metallic container comprises an internal container and an external container where end faces are joined together with a space provided between the internal and external containers. The space between the internal container and the external container is vacuumed.

Abstract: A heat insulating container is described, including an outer glass container and an inner glass container housed therein with a gap formed in-between as a heat insulating layer. A radiant heat preventive film containing a metal oxide is disposed on at least one of the external surface of the inner container or the internal surface of the outer container, wherein the radiant heat preventive film has a reflectivity of 35% or higher with a wavelength of 15 ?m. When the thickness of the radiant heat preventive film is 3000 ?, the Hall mobility “x” (cm2/V·s) and the carrier concentration “y” (cm?3) of the same satisfy the following formulae: y??5×1020x+2×1021 and y??6×1018x+3×1020. When the thickness of the radiant heat preventive film is 5000 ?, x and y satisfy the following formulae: y??5×1020x+3×1021 and y??6×1018x+7×1020. Such radiant heat preventive films can have high reflectivity.

Abstract: The present invention provides a vacuum insulating double vessel having transparent slits and a method for manufacturing the same which can form transparent slits safely and simply without using any particular equipment and particular chemical and which can be mass-produced at a low cost. This vacuum insulating double vessel includes a vacuum insulating layer provided between an inner vessel and an outer vessel of the double vessel made of a transparent material, and metal films applied to the outer surface of the inner vessel and the inner surface of the outer vessel which face the vacuum insulating layer, and the vacuum insulating double vessel comprises strip-shaped metal film unapplied portions in a vessel height direction in the metal film applied portions, and a plurality of opening vestiges, on the outer vessel, which result from sealing a plurality of openings used for injecting and discharging chemical solutions for applying the metal films, and used as air passages.

Abstract: A heat insulating container and its manufacturing method is provided. The heat insulating container comprises an inner container and an outer glass container, in which the breakage of the glass containers can be prevented even if a minute flaw is formed on either of the glass containers. The insulating container possesses a superior radiant heat insulating capability. The inner glass container is housed in the outer glass container with a gap in between, which air-gap functions as a heat insulating layer. A radiant heat preventive film containing metal oxide is provided at least either on the outer surface of the inner glass container or on the inner surface of the outer glass container with an intermediate film containing SiO2 in between.

Abstract: The present invention relates to a heat-insulating cooking container comprising: a heat-insulating outer container and an inner container having an inner-container cover, the inner container being accommodated in the heat-insulating outer container, an aperture portion of the heat-insulating outer container being openably and closably covered by a heat-insulating-outer-container cover, wherein: a thermometer is installed on the heat-insulating-outer-container cover; a temperature-sensing member of the thermometer unit is located on an interior-surface side of the heat-insulating-outer-container cover; and the inner-container cover covers the temperature-sensing member upon opening the heat-insulating-outer-container cover and placing the inner-container cover on an interior surface of the heat-insulating-outer-container cover.

Abstract: A thermal-insulation container with electric heater comprising an inner container and an outer container, said inner container being housed into the outer container integrally therewith so as to define a closed space separating the same from the outer container comprises a highly-resistive metal oxide film formed on an outer surface of said inner container facing said closed space, and an electrode unit provided on the highly-resistive metal oxide film facing said closed space for applying an electric current thereto.
