Claim:
1. A container of a gaseous, gas borne or droplet substance having: an inner pressurised container for the substance, a substance-release valve device sealed across an end of the inner pressurized container and having a spring, a spout at a spout end of the inner pressurized container, which is displaceable inwards of the inner pressurized container against the spring of the valve device for substance release, the container also including: an outer enclosure enclosing the inner pressurized container along its length, at least partially across its end remote from the spout and partially at its spout end, the outer enclosure and the inner pressurized container being arranged to be capable of reacting to cause displacement of the spout inwards of the inner pressurized container for substance release; a mechanical counter accommodated within the outer enclosure for counting substance release displacements of the spout, wherein the counter is arranged to be incremented on displacement of the spout, and the counter includes a rotatable member indexed by one increment on each displacement of the spout, wherein the rotatable member is a portion of the inner pressurised container or a sleeve fast with the container, the container or the sleeve being adapted to be indexed by one increment on each displacement of the spout, or the rotatable member is a member internal of the outer enclosure, extending around the inner pressurized container, the rotatable member having a helical track; a window in the outer enclosure for viewing the count of the counter extending axially and/or circumferentially of the outer enclosure; and an indicator adapted to co-operate with the helical track which operates as an indicator by movement along the window.
