Abstract
A pump dispenser package that includes a container having a cylindrical neck with an axial edge that surrounds a container outlet opening. The neck has an internal circumferential channel that extends around the neck in a plane adjacent to but spaced from the axial edge of the neck. A pump assembly has a cylindrical housing with an integrally formed radially outwardly extending flange. A flat annular adapter ring has an inner edge secured to the pump housing in abutment with the flange and an outer edge received in the internal channel in the container neck to mount the pump assembly to the container. In the preferred construction, the pump housing has a radial ledge spaced from the flange, and the inner edge of the adapter ring is captured between the ledge and the flange. The outer edge of the adapter ring preferably has an annular peripheral bead that is received by snap-fit within the channel in the container neck. The adapter ring has a flat upper surface that is coplanar with the axial edge of the neck.
