Claims

[Scope of Claim for Utility Model Registration] 1. A foam insulation box body made by joining the opening edges of the inner box and outer box forming a double wall with a plastic breaker, and filling the double wall with polyurethane foam. There it is,
´ When filling the polyurethane foam, a synthetic resin sealing material is placed along the inner surface of the breaker in advance to protect against urethane attack, and the opening edges of the inner and outer boxes are lined with the bonding surface of the breaker and the synthetic resin. The synthetic resin seal is inserted between the plastic sealing material and the breaker, and is positioned so that a part of the breaker is on the lower side, and a predetermined amount of the foamed polyurethane stock solution is poured into the synthetic resin seal through the injection port provided on the back of the outer box facing the breaker. A foam insulation box characterized by injecting foam into the material. 2. The foam insulation box according to claim 1, wherein the synthetic resin sealing material is a flexible synthetic resin foam sheet. 3. The foam insulation box according to claim 2, wherein the flexible synthetic resin foam sheet is a polyethylene foam sheet.
