Abstract: A device for keeping two products in respective containers separate from one another, and for mixing them when desired for use. A seal including a sealing plate is connected to one of the containers, and a closure partition equipped with a seat is connected to the other of the containers. In a closed position, the sealing plate seals against the seat, but a relative translational displacement of the two containers moves the plate away from the seat, opens the seal, increases an internal volume of the assembly of the two containers, and allows the products to mix.
