Abstract
A pump dispenser comprising a container having a neck () to which the pump is attached. A pump body () has an outward flange () through which it is supported on the edge of the container neck (). A body/neck rotation stop mechanism () is provided by an interlock engagement between the pump body and the container neck, and has widely-spaced interlock projections () on the container neck (), e.g. one or two projections, each having a circumferentially-directed abutment face (). A series of spaced interlock teeth () projects down from the outward flange () of the pump body and these have respective abutment faces () to engage the neck projections and limit relative rotation of the pump body and neck. This can assure reliable action of a plunger-locking mechanism of the dispenser.
