A package for dispensing a flowable material is disclosed. The package includes an interior chamber for holding the flowable material, a coupling insert located within the chamber and a piercing member. The piercing member includes a dispensing tube and is arranged to pierce through the package to communicate with the chamber and thereafter to snap-connect to the coupling insert. The contents of the package can then be dispensed from the package via the dispensing tube. The coupling insert is arranged to be moved to any desired position within the chamber. The package's wall may be constructed, e.g., be transparent and/or include target indicia thereon, to facilitate the positioning of the coupling insert at the desired position.
