Abstract

Cette invention concerne un sachet d'infusion qui comporte une paire de compartiments scellés (12a, 12b) contenant la matière à faire infuser, et rassemblés au niveau d'extrémités opposées du sachet. Un cordonnet (14), attaché en son milieu à une région de raccordement (8) située entre les deux compartiments au niveau d'une desdites extrémités, comporte des tirettes disposées entre les compartiments dudit accessoire, et maintenues, de façon mobile, à l'autre extrémité du sachet, lesdites tirettes pouvant être écartées l'une de l'autre de façon à comprimer le sachet. Pour fabriquer le sachet, les compartiments sont initialement formés de bout en bout, et assemblés au niveau de la région de raccordement. Une partie intermédiaire (16) du cordonnet est fixée à la région de raccordement avant que les compartiments ne soient pliés en deux pour rassembler leurs extrémités opposées, les tirettes du cordonnet se trouvant alors entre lesdites extrémités opposées. Lesdites extrémités opposées sont alors attachées l'une à l'autre de manière à permettre le mouvement des tirettes du cordonnet entre ces extrémités dans le but de comprimer le sachet.
