Abstract

L'invention concerne un contenant, pour le stockage de médicaments, qui est configuré à partir d'un corps de contenant creux, d'un élément couvercle qui recouvre le corps de contenant, d'une feuille qui est ajustée sur la base de l'élément couvercle, et un médicament pulvérulent qui est stocké à l'intérieur du corps de contenant. Le corps de contenant est configuré à partir d'un corps cylindrique et d'une embouchure qui est disposée sur l'extrémité du corps. Le corps est pourvu d'une partie résistante à la déformation qui ne se déforme pas ou qui est difficile à déformer lorsqu'un liquide de solubilisation est introduit dans l'espace de stockage, et d'une partie facilement déformable qui augmente le volume de l'espace de stockage par sa déformation. Le médicament est dissous par un liquide de solubilisation qui est introduit par une seringue, etc., à travers l'embouchure du corps de récipient.
