  • Publication number: 20140276442
    Abstract: A device (10) comprises a first barrel defining a first chamber for holding a first composition. The first chamber has at least one side wall and a distal end wall defining a dispensing nozzle (22). At least one flow channel (32) is formed in the at least one side wall and distal end wall, extending across the distal end wall in helical fashion. The device (10) further comprises a second barrel (14) defining a second chamber for holding a second composition. The second chamber has at least one side wall and distal end wall. An annular seal (86) is formed at the distal end of the second barrel (14). The at least one side wall defines at least one orifice (58) proximal to the seal (86). A plunger (16) is operable to drive the second barrel (14) into the first chamber to displace the first composition out through the nozzle (22) and to bring the annular seal (86) into contact with the distal end wall of the first chamber.
