Abstract
A device (1) for the extemporaneous mixing of N constituents (A, B) has N compartments (2a, 2b), each having a first end (22a, 22b) and a second end (24a, 24b) on the opposite side to the first, each of the first and second ends being surmounted by a neck (22a, 24a; 22b, 24b) delimiting an opening (12). (N-1) intermediate obturators (14) separate each compartment in a detachable manner from the compartment or compartments which are adjacent thereto when the N compartments are placed on one another. An actuator (18) is provided for ejecting the (N-1) intermediate obturators (14) for effecting the mixing of N constituents, and first end obturators (8) and second end obturators (9) are provided for obturating the end openings of the first compartment (22a) and of the N.sup.th compartment (24b). One of the first or second end obturators has an opening (26) for the dispensing of the mixture. The first and second ends of any of the N compartments can receive any of the said obturators.
