Abstract

L'invention concerne un matériau d'amortissement comprenant deux feuilles souples (11, 12) et une feuille extensible (15) maintenue entre les feuilles souples. Ce matériau est caractérisé en ce que les feuilles souples et la feuille extensible sont fusionnées ou collées les unes aux autres, par l'intermédiaire de plusieurs lignes parallèles les unes par rapport aux autres et en ce que la feuille extensible n'est pas rétractée. Quand la feuille extensible se rétracte, les feuilles souples prennent la forme de corps tubulaires (21) de forme générale circulaire en section transversale et les parties fusionnées (20) ou les parties collées des feuilles souples conservent une force d'expansion externe (flèche (b)) de manière qu'une action d'amortissement puisse être mise en oeuvre contre un choc et de la pression, la feuille extensible étant formée au moyen d'un matériau possédant une contractilité thermique et une capacité de reprendre la forme. Par conséquent, quand le corps d'un sac est fabriqué au moyen du matériau d'amortissement comprenant la feuille à contraction thermique, un article peut être conservé sous pression par contraction de la feuille à contraction thermique une fois l'article placé dans le sac.
