Benefits of technology

[0008] Accordingly, in the light of the foregoing description, it is an object of the present invention to provide a heat insulating container that is excellent in thermal insulating capability and a manufacture method of the same.

Problems solved by technology

However, a radiant heat preventive film formed from a metal oxide usually has a low performance in preventing radiant heat because of the restrictions of the manufacturing conditions.
Therefore, it is difficult to produce a heat insulating container that is excellent in heat insulating capability.

Embodiment Construction

[0031] Refer to FIG. 1, which illustrates a sectional view of a heat insulating container according to a preferred embodiment of the present invention. In the heat insulating container 1 of the preferred embodiment, an inner glass container 2 is housed in an outer glass container 3 with a gap 4 formed in-between as a heat insulating layer.

[0032] The inner container 2 and the outer container 3 are joined together at respective opening ends 2b, 3b and integrated. In a preferred embodiment, both containers are joined together in an airtight manner by heating and softening the opening ends 2b and 3b, so as to make the gap 4 airtight.

[0033] The shape of the inner container 2 or the outer container 3 is not specifically restricted, and can be a cylinder shape, a ball shape or the like. However, in order to keep the width of the gap 4 between the inner container 2 and the outer container 3 approximately uniform, it is preferred that the inner container 2 and the outer container 3 have si...

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 μm. When the thickness of the radiant heat preventive film is 3000 Å, 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 Å, 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.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of Invention [0002] The invention relates to a heat insulating container having a double-wall structure and a manufacture method therefor. More specifically, the invention relates to a heat insulating container that includes an inner glass container and an outer glass container with a gap formed in-between. [0003] 2. Description of Related Art [0004] A heat insulating container comprising an inner glass container and an outer glass container, such as a vacuum flask, has been in common use. The heat insulating container has a structure comprising an inner glass container housed in an outer glass container with a gap formed in-between. In such a heat insulating container, the gap is in a vacuum, or a low-thermal-conductivity gas (for example, argon, krypton or xenon) having a thermal conductivity lower than that of air is sealed within the gap, so that the gap can serve as a heat insulating layer. Furthermore, in this type of heat insulating...
