A method of packaging a resiliently compressible article (10) comprises the steps of inserting the article into a tube of deformable material (22) such that excess material is provided at the ends of the tube. A first end (24) of the tube is then sealed closed. Air is then evacuated from the tube through the second end thereby deforming the tube around the article and causing the article to compress. While a vacuum is maintained in the tube, the second end of the tube is sealed closed. A containment sleeve (26) is fitted over the sealed tube to maintain the article in a compressed state. When the article is unpackaged, the containment sleeve is reversed and the tube is allowed to expand in a gradual controlled fashion by the bleeding of air back into the tube.
L'invention concerne une méthode d'emballage d'articles compressibles (10), de manière réversible. L'article est tout d'abord placé dans un tube en matériau déformable (22) de telle façon que le matériau en excès se retrouve aux extrémités du tube. Une des extrémités (24) du tube est ensuite scellée. L'air contenu dans le tube est ensuite chassé par l'autre extrémité, ce qui provoque la déformation du tube autour de l'article et la compression de ce dernier. Alors que le tube est maintenu sous vide, la seconde extrémité est scellée elle aussi. Un manchon de confinement (26) est placé autour du tube scellé de façon à conserver l'article à l'état comprimé. Au moment du déballage, le manchon de confinement est retenu et le tube peut progressivement reprendre sa forme initiale au fur et à mesure que l'air y pénètre.
