Abstract
The container (1) is intended for the separate storage of active compositions, especially of liquids or solutions, and for their subsequent mixing just before use. It comprises at least three compartments (3, 4, 5) separated from one another by leakproof seams (6) of the material of the envelope (2), sealable inlet passages (7, 8), sealed transfer passages (10, 11) and a sealable outlet passage (9). The envelope is made of a polymerized and homogeneous flexible material which is chemically inert to each of said compositions and to their mixtures.
