Abstract
A dispenser is specially adapted for being carried in handbags or pockets. A nozzle is pivotable between a projecting and a retracted position. When in the retracted position it lies within the envelope of a casing and a pump head on which it is mounted is blocked from any movement by abutment against a part on the casing, this part also acting to block the outlet end of a passage in the nozzle to prevent leakage of any material left in that passage after the last use of the dispenser. At the same time the inlet to the passage is closed off by a wall of the passage. When the nozzle is in its projecting position, the inlet and the passage are put in communication and the head may be depressed to express a charge through the nozzle.
