Title:
MANUFACTURE OF HEAT INSULATION BOX BODY
Document Type and Number:
Japanese Patent JP3820538
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve an injection method of a foam heat insulation raw material mixed liquid into the inside of an adiabatic wall of a heat insulation box body which is made small by being provided with a vacuum heat insulation panel.
SOLUTION: In a manufacture of a heat insulation box body in which a row material mixed liquid of a foam heat insulation material is injected into the space of the inner part of an outer shell 31 constituting a heat insulation wall so as to fill the space, a vacuum heat insulation panel 1 is fixed on a rear face plate 15 being on the rear face of the outer shell 31, and a form heat insulation raw material mixed liquid is injected inside the outer shell 31 from the rear face side via a groove 26 constituted of a thickness face part 1a of the vacuum heat insulation panel 1, an outer side plate 17 of the outer shell 31 being in a side part of the outer shell 31, and the rear face plate 15 in a state in which the rear face side is lowered.
