Abstract
A dispenser pump has pump chamber (34) whose volume is variable to draw up or discharge material, by the axial movement of a cup (25) on a stationary hollow stem (12). The seal (16) between them slides on an inner wall of the cup. A collector (30) at the lower end of the cup causes any material leaked past the seal to be guided inwardly to apertures (33) where it may drop to a body part (9) and pass via apertures (11') to a container (1) of the material.
