摘要

PROBLEM TO BE SOLVED: To provide a heat insulation bag which firstly improves structural strength of a handle integrally provided with a bag body or improves structural strength of a carrying base of the handle and secondly realizes improvement in operability of a fitting fastener provided below the handle. SOLUTION: A plurality of thermoplastic resin face materials 4 and 6 having an aluminum deposited surface 3 on at least one of surfaces are two-folded in a laminated state, and welding seals 8 and 8 to fix the materials 4 and 6 to each other on both sides are applied. The heat insulation bag 1 having folded rims of the entire materials 4 and 6 as a bag bottom 7 and end surfaces surrounded by end rims of the materials 4 and 6 as a bag opening 10 is thus provided. A fixing surface 12 is formed wherein the welding seals applied in a widthwise direction for continuously fixing the entire materials 4 and 6 with a predetermined depth range extending from the opening 10 toward the bottom 7 serve as a reinforcing portion 9. A handle hole 2 passing through the entire materials 4 and 6 is provided within the fixing surface 12, thereby obtaining the heat insulation shopping bag 1. COPYRIGHT: (C)2003,JPO
