A device (10) includes a First Cylinder defines a First Chamber for accommodating a First composition. The First Chamber has at least one side wall and a distal end defining a dispensing nozzle (22).In at least one wall and lateral Wall of the distal End is formed at least a Channel Passage (32) that extends through the distal end Wall in helical form. The device (10) also includes a Second Cylinder (14) that defines a second Chamber to accommodate a Second composition.The second Chamber has at least one side wall and a distal end Wall. At the distal end of the second Cylinder (14) form a Sealing ring (86). The at least one side wall defines at least one Hole (58) proximal to the seal (86).A piston (16) can be operated to push the second Cylinder (14) in the first Chamber to move the first composition out through the nozzle (22) and to make the seal ring (86) in contact with the Wall of the distal end of the first Chamber.Thus, the seal (86) deforms and allows Fluid Communication between the Holes (58) and the step (32 channels). The Piston (16) can move subsequently in the second Chamber to move the second composition Outward through the opening (58) and the step (32 channels) to the nozzle (22).Un dispositivo (10) comprende un primer cilindro que define una primera cámara para alojar una primera composición. La primera cámara tiene por lo menos una pared lateral y una pared de extremo distal que definen una tobera dispensadora (22). En la por lo menos una pared lateral y la pared de extremo distal, se forma por lo menos un canal de paso (32) que se extiende a través de la pared de extremo distal en forma helicoidal. El dispositivo (10) comprende además un segundo cilindro (14) que define una segunda cámara para alojar una segunda composición. La segunda cámara tiene por lo menos una pared lateral y una pared de extremo distal. En el extremo distal del segundo cilindro (14) se forma una junta de estanqueidad anular (86). La por lo menos una pared lateral define por
