An overcap (12) may be independetly rotatably disposed on the plunger head (14) and include a side wall overlying the discharge orifice (22) in a condition of non-use.The side wall may include an opening (20) disposable in alignment with the discharge orifice (22) upon rotation of the overcap (12) relative to the plunger head (14). A container closure (16) may be provided for affixing the plunger head (14) and the overcap (12) relative to a container. The plunger head (14) may be axially reciprocable relative to the container closure (16) and may otherwise be locked relative to the container closure (16) when in first and second orientations.
