Abstract

A dual component dispenser for simultaneous delivery of two fluid products at a preset ratio, includes a cylindrical container having in series a front (28) and a back chamber (30) in axial alignment, each of said chambers (28, 30) having an interior volume being defined by a fixed front wall (11, 24), side walls (12, 14), and a plunger (20, 22). The plungers (20, 22) are formed such that they are slidably movable inside the side walls (12, 14) of their respective chambers, wherein movement of the back plunger (22) effects synchronous movement of the front plunger (20). The dispenser further includes a nozzle (10) attached to the front wall (11) of the front chamber (28) and a conduit (26) within the container for conveying the content of the back chamber (30) directly to the nozzle (10). The conduit (26) is a cylindrical telescopic tube consisting of a front inner tube (16) and a back inner tube (18). The dispenser further includes a flow connection (46) to allow discharge of the content of the back chamber (30) into the back inner tube (18). The front inner tube (16) extends between the fixed front walls (11, 24) of the front and back chambers (28, 30). The back inner tube (18) is rigidly fixed between the plungers (20, 22), whereby the fixed front wall (24) of the back chamber (30) has an aperture (25) to slidably engage the back inner tube (18), and the front plunger (20) has an aperture (21) constructed to slidably engage the front inner tube (16) for movement thereon.
