ABSTRACT:
A household liquid dispenser has a spout fitment with discontinuous beads or screw threads which define axial channels to interface with a pump inlet in a lock and key arrangement so as to maintain consistent quality of liquids dispensed by preventing the substitution of product refills of uncertain quality. Refills may be readily manufactured and at low cost. Mechanical and motorized dispensers may be used with the inventive spout fitment.
