A container for dispensing an active agent, which container comprises a housing (1) containing said active agent, a cap (4) connected to the housing and gravity-actuated locking means for locking together the housing and the cap, said cap being in an unlocked state when the container is held in a first orientation, but when tilted or rotated out of said orientation said locking means are urged by gravity into locking engagement to lock the cap; wherein said locking means comprise a first locking element (12) that is connected to the cap and is moveable in conformity with the cap inside the housing and a second locking element (22) that is moveable under force of gravity on a profile (17,18) formed on the internal surface of the housing in response to any tilting or rotating movement of the container out of the first orientation to engage the first locking element in locking engagement; characterised in that the second locking element is formed of a material that permits the second locking element to move freely under gravity on the housing profile even in the presence of an electrostatic field. |
