- a pair of hollow tubes each defined by intersecting curved and flat outer walls along a longitudinal length thereof, the flat outer walls of the pair being positioned juxtaposed to one another and being provided with at least two elongate outwardly projecting ribs with one of the two flat outer walls having at least one more rib than a second of the flat outer walls, each of the tubes having a closed and an open end, an exit orifice and a coupling ridge being formed at the open end;
- a manifold for directing separate flow of material from each of the tubes being positioned over the open ends, the manifold including a skirt wall with projections on an inner surface for engaging the coupling ridge and a pair of non-communicating flow chambers terminating in respective dispensing openings;
- a cap fitting over the dispensing opening; and
- a metering valve located between the exit orifice and the dispensing opening in at least one of the separate paths.
