Abstract: PURPOSE:To provide a vacuum heat insulating pack which can be manufactured industrially at low cost while being stabilized in performance by making up the pack of core material, a container covering the core material, and of a barrier member, and concurrently providing the barrier member for a part of the container. CONSTITUTION:This pack is made up of core material 2 made of hard urethane foam in a continuous bubble structure and the like, a container 4 which is made from a plastic laminate film 3 under vacuum, a barrier member 6 made from a plastic-metallic foil laminate film 5, and of a cover member 8 made from a plastic laminate film 7. The barrier member 6 is fitted on the inner surface of the container 4 by means of heat sealing and the like, the core material 2 made of hard urethane foam in a continuous bubble structure and the like, is filled therein thereafter, its inner section is decompressed, and the cover member 8 is hermetically sealed by means of heat sealing thereafter. Since the barrier member 6 having the metallic foil is partially stuck thereon as mentioned above, less thermal conduction by the metallic foil takes place.

Abstract: PURPOSE:To improve the continuous bubble fraction of a skin part and prevent any foam scraps from occurring in getting rid of cut and removal parts by mounting a permeable face member on a jig with permeability as well, and manufacturing a continuous cell structural hard urethane foam panel as a core material in this face member. CONSTITUTION:In foaming of a hard urethane foam block 4, a sheet of paper and a nonwoven fabric or the like with permeability, as a surface member, are mounted and put into an open panel jig 5, but this jig 5 is also composed of a material with permeability such as a ceramic foaming body or the like. Subsequently, the hard urethane foam block 4 is cut into an optional size, and a hard urethane foam panel 7 with foam is made on the central part and the surface part. Then, adsorbed moisture or the like is heated and evaporated, and it is covered with a vessel 3 consisting of a metal-plastic laminate film, the inner part is decompressed and hermetically sealed, obtaining an insulated body 8. Since the panel 7 being obtained in this way is continuously bubbled to perfection even on the surface part, a large quantity of foam scraps should not be produced.

Abstract: PROBLEM TO BE SOLVED: To reduce heat conduction by inserting a material blending core having-hard urethane foam powder and water absorbent having specific surface area larger than the urethane powder in an outer cover material to decompress the inside thereof to seal up. SOLUTION: Uethane powder 2 pulverizing hard urethane foam is blended with a water absorbent 3 having 5-20 times of specific surface area in comparison with the urethane powder. After a material blending the urethane powder 2 and water absorbent 3 is heated and dewatered at temperature of 120 deg.C-250 deg.C, the plate-like material resulting from pressure molding under conditions of 5-100 kg/cm is inserted in an outer cover material 4 formed in the shape of a bag by heat welding. Then, the outer cover material 4 is put in a chamber 12 of a vacuum packing machine 10, the end face 13 of an opening in the outer cover material 4 is mounted to a heat sealing machine 11, and the inside of the chamber 12 is decompressed to seal up the outer cover material 4. Accordingly, the scatter of the powder is prevented, and work efficiency can be promoted.

Abstract: PROBLEM TO BE SOLVED: To light weight, reduce cost, improve performance, and recycle urethane foam by using powder granulated by highmolecular coagulant organic powder, in a vacuum heat insulator filled core material formed of at least organic powder and inorganic powder in an outer covered material. SOLUTION: A vacuum heat insulator 1 used as the heat insulating material such as a refrigerator is manufactured in such a way that pressure is reduced and exhaust is carried out so as to suppress pressure of an inner part to about 0.1mmHg after a core material formed by mixing urethane powder granulated by highmolecular coagulant and wet silica powder with each other is filled in an outer covered material. In this case, ethyl cellulose is used as the highmolecular coagulant, the adding rate of the ethyl cellulose is set to be within 1weight% or more to 30weight% and less. Granulation is carried out by the highmolecular coagulant, and thereby, the particle diameter of organic powder is regulated optionally. It is thus possible to reduce a solid heat conductivity by contact of excessive small diameter particle, and it is also possible to reduce a heat conductivity.

Abstract: PURPOSE: To enable heat insulating properties to be maintained over a long period by using a laminate film formed of at least a surface protective film, a metallic layer and an inner layer film having the specified thickness for a sheath material in a vacuum heat insulating body sealed after decreasing pressure in the sheath material in which a core material is filled. CONSTITUTION: A vacuum heat insulating body 1 is constituted of a core material 2 and a sheath material 3. This vacuum heat insulating body 1 is manufactured by filling a core material 2 formed of hard urethane foam having open cells, vacuum-dried for two hours at 120 deg.C is filled into the sheath 3, decreasing pressure inside it and then being sealed. In this case, a laminate film composed of a surface protective film 6 made of polyethylene terephthalate, a metallic layer 5 such as aluminum foil and an inner layer film 4 having the thickness of 50μm or more and 150μm or less is used as the sheath material 3. A film formed by laminating polyacrylonitril resin and nylon resin is preferably used as the inner layer film.
