A directional dispensing package which is easily shipped, filled and assembled is disclosed. The package includes a retaining opening into which a pump may be snap-fit by inserting the pump through an open end of the package. The package and pump can be assembled at a production site, and are thereafter shipped to a filling site with a bottom portion. The package can be filled through the open bottom end, and then the bottom portion sealingly affixed to the package. The package may include an integrally-molded dip tube structure, which can also serve as the pump housing. The dip tube structure may also be snapped into the package. The dip tube structures of the present invention allow easy assembly while preventing leakage. Various devices for allowing inverted dispensing are disclosed. The device of the present invention can be filled and finally assembled with a minimal number of steps, and is therefore particularly suited for quick-turnaround marketing.
