    Abstract: PURPOSE: To provide a thermally insulating material that is prevented from the permeation of carbon dioxide gas contained in the bubbles of the thermally insulating material and deformation of the thermally insulating material, in the thermally insulating box body that is used for a refrigerator and a showcase. CONSTITUTION: A polyvinylidene chloride sheet 6 is joined to a part of a thermally insulating box body, that is plastic inner box 2. The polyvinylidene chloride sheet 6 has a better gas barrier characteristic. The space part 4 of it is filled with a thermally insulating material 5. Therefore, the poly-vinylidene chloride sheet 6 lies between the thermally insulating material 5 and the plastic inner box 2.

    Abstract: PURPOSE:To improve an assemblying work characteristic in a thermal insulated box to be used in a refrigerator or a show case. CONSTITUTION:A thermal insulated box is comprised of a vacuum thermal insulated plate 8 arranged in a thermal insulated space 5 formed by a plastic inner box 2 and a metallic outer box 3, formed to be adapted for a shape of a condensing pipe 16 in advance and fixed with adhesive agent to an inner surface of the outer box 3 with the condensing pipe 16 being held between it and the outer box 3; some embedded parts such as a freezing cycle suction pipe 13 embedded between the vacuum thermal insulating plate 8 and the inner box 2 through a spacer 17 against the vacuum thermal insulating plate 8, an electrical wiring 14 and a defrosted water drain pipe 15 and the like; and foamed thermal insulating material 7 filled in the thermal insulating space 5. Since the vacuum thermal insulating plate 8 is fixed to the inner surface of the outer box 3 with adhesive agent, a space between the vacuum thermal insulating plate 8 and the inner box 2 can be made large, resulting in that the embedded parts may easily be arranged and their assemblying operation can be improved.

    Abstract: PURPOSE:To cover an absorbing heat quantity reduction method which is designed to save energy for a refrigerator or a show case in terms of magnet gaskets of a refrigerator or a show case and provide a magnet gasket capable of enhancing insulation performance by compounding microbaloons into a magnet gasket material. CONSTITUTION:A magnet gasket is installed to the outer periphery inside a refrigerator door, and is provided with an air chamber in the upper part of base 6 and a magnet chamber 7 in the upper part of the air chamber. A magnet gasket bulkhead s extrusion-formed in irregular shape by using vinyl chloride resin to which the microbaloons 13 are compounded as a material.

    Abstract: PURPOSE: To prevent a thin wall portion of an inner box from bulging out by a method wherein a heat insulating box is comprised of an inner box, an outer box and a foam heat insulating material, and the inner box is provided with a rib having holes with a diameter through which the foam heat insulating material can not enter and further having holes through which a foam producing agent can escape. CONSTITUTION: An inner box 13 made of plastic material formed under a vacuum formation is constructed such that thin wall portions 14 such as corners of it are provided with elongated protrusion ribs 11. The ribs 11 have holes 12 at their extremities. Such an inner box 13 is assembled into an outer box 3 and then a foam heat insulating material 6 is filled in a closed space 4. The thin wall portions 14 at the inner box 2 of the heat insulating box 1 are provided with the elongated protrusion ribs 11 having holes 12 therein through which fluorocarbon gas 5 escapes, thereby even if a cooling operation is stopped, a temperature within the heat insulating box is increased due to temperature of surrounding atmosphere, fluorocarbon gas 10 within the foam heat insulating material is expanded and flows into a clearance 7 between the inner box 2 and the foam heat insulating material 6, deformation of the thin wall portions of the inner box 2 is preventable because the gas is discharged through the holes 12.
