Claim Text:
1. A device for packaging, conserving, and extemporaneously preparing a plurality of active principles, said device comprising: a reservoir having at least one compartment containing at least one volume of liquid, said reservoir including a neck that defines a dispenser opening of the reservoir; a head that is movable relative to said reservoir between a first position for conservation, in which said head is in its distal position relative to the reservoir, and a second position for preparation, in which said head is in its proximal position relative to the reservoir; leaktight closure means for closing the neck of said reservoir; and rupture means for rupturing said leaktight closure means; wherein said leaktight closure means are formed by a leaktight blister that contains at least two active principles, said blister having at least two compartments that are separated by longitudinal and/or transverse and/or superposed partitions, each compartment containing an active principle, said blister being fastened on the neck of said reservoir so as to close said reservoir in leaktight manner, such that after opening said blister by said rupture means, said active principles enter into contact with the liquid and dissolve therein; wherein a sealing gasket is interposed between the head and the reservoir so as to guarantee sealing after the blister has been opened by the rupture means; wherein the volume of said liquid contained in the reservoir is less than 5 mL; and wherein said head includes a filter and a dose-taking membrane, an internal component being inserted into said head so as to define a dose-taking chamber in the volume defined in said internal component between said filter and said dose-taking membrane.
