Abstract

Exemplary pumps, nozzles and refill units are disclosed herein. An exemplary refill unit includes a container, a pump and an outlet nozzle. The outlet nozzle has a lower conical shaped portion that reduces in cross-sectional area in the direction of fluid flow. The conical shaped portion has a helical groove about its inner surface and the helical groove has an end proximate an outlet. Another exemplary refill unit includes a container, a pump and an outlet nozzle. The outlet nozzle (400) has a lower portion (420) that has a passage. At least a portion of the walls of the passage contain a plurality of partial conical shapes (424A-G) that intersect and the passage has a cross-sectional area that reduces along the fluid flow path. The outlet (424) has a multi-lobed cross-section.
