Synthetic resin make adiabatic container and synthetic resin make adiabatic cover

摘要

PROBLEM TO BE SOLVED: To reduce heat transmission loss from a vessel mouth base part and a cover peripheral part by forming a heat transmission reducing part with thickness reduced in the neighborhood of the opening mouth part of an inner vessel and in the neighborhood of the edge part of the lower face wall of a cover. ;SOLUTION: An outer vessel 3 and the inner vessel 4 are joined to make a double wall vessel according to the methods of oscillation welding or spin welding for the mouth base parts 11 and 12 of each. It is desirable to enclose the low-temperature electroconductivity gas to a heat insulation layer 6 formed between the outer and inner vessels 3 and 4. A heat transmission reducing part 14 with thickness reduced is formed in the neighborhood of the part 12 of the vessel 4. A cover 2 is obtained by joining an upper and lower surface walls 21 and 22 to be one body by connecting at the edge parts 29 and 30 of the walls 21 and 22 by inserting a space part 23 between them according to the method of oscillation welding and spin welding. The low- temperature electric conductivity gas is enclosed to a heat insulation layer formed between the walls 21 and 22. The heat transmission reducing part 32 with thickness reduced is formed in the neighborhood of the edge part 30 of the wall 22.;COPYRIGHT: (C)1998,JPO
