Abstract

The thermal bag ( 2 ) is made of thermally insulating composite material folded to form a bottom and welded along lateral borders ( 3 ) to form a body ( 1 ) of the bag with a mouth ( 5 ) at the level of which a handle ( 7 A, 7 B) is applied. The composite material defines a bottom folded in an accordion-like fashion opposite the mouth of the bag, and a laminar stiffening element ( 15 ) of the accordion-like bottom is disposed inside the bag.
