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; andan indicator adapted to co-operate with the helical track which operates as an indicator by movement along the window. 2. A container as claimed in claim 1, wherein the counter is arranged at an end of the outer enclosure, for transmitting spout-displacement force between the inner container and the outer enclosure and counting occurrences of such force. 3. A container as claimed in claim 2, wherein the counter is a removable or irremovable mechanical counter. 4. A container as claimed in claim 1, wherein the mechanical counter includes a dual set of ratchet teeth and pawls, with angular incrementation determined by the ratchet teeth. 5. A container as claimed in claim 4, wherein the mechanical counter includes a dual set of ratchet teeth and pawls, one of either of the teeth and the pawls being displaced with the spout the other being fast with the outer enclosure and the rotatable member being incremented partially by one of the dual set of teeth on inwards displacement of the spout and partially by the other of the dual set of teeth on return outwards displacement of the spout, or a single set of ratchet teeth and at least one pawl and a frictional member restraining the rotatable member, one of either of the teeth and the pawls being displaced with the spout the other being fast with the outer enclosure and the rotatable member being incremented by the pawl and teeth on inwards displacement of the spout and held by the frictional member on return outwards displacement of the spout. 6. A container as claimed in claim 5, wherein one of the sets of teeth and pawl(s) or the frictional member, whichever is provided, is arranged at the end of the rotatable member having the helical track remote from the spout and co-operates with the end of the outer enclosure on incrementing of the rotatable member. 7. A container as claimed in claim 1, wherein the rotatable member has a curved surface; andthe indicator:engages the helical track for movement of the indicator, and hasa curved inner face engaging the rotatable member at the helical track for location of the indicator circumferentially of the rotatable member, anda flat outer face engaging the window for locating the indicator at the window circumferentially of the outer enclosure. 8. A container as claimed in claim 1, wherein the indicator and the outer enclosure have a complementary non-circular cross-section for locating the indicator in the window circumferentially of the outer enclosure. 9. A container as claimed in claim 1, wherein the rotatable member having the helical track comprises a circular cylindrical member around the inner pressurized container and the helical track is a channel or groove in the cylindrical member or a rib or ridge on the cylindrical member. 10. A container as claimed in claim 9, wherein the rotatable member having the helical track, the indicator and the window are all adapted for plunging movement of the member and the indicator with the spout, a return spring being provided for return movement on outwards movement of the member and indicator after inwards, dispensing movement. 11. A container as claimed in claim 10, wherein the rotatable member having the helical track, the rotatable member having the helical track is axially located with respect to the outer enclosure and a separate member plungeable with respect to the outer enclosure is provided, the plungeable member being adapted for driving the helical track member in rotation. 12. A container as claimed in claim 9, wherein the plungeable member is provided with:means for irrotationally locating it with respect to the outer enclosure; andpawls or teeth for rotationally driving the rotatable member;cooperating teeth or pawls respectively being provided on the rotatable member having the helical track. 13. A container as claimed in claim 1, wherein the helix of the helical track is regular, or the helix of the helical track is less steep in its portion occupied by the indicator on initial use of the source and steeper in its portion indicating imminent exhaustion of the container. 14. A container as claimed in claim 1, including an end cap of the outer enclosure at its end remote from the spout, the end cap being connected to an outer sleeve of the enclosure, at a position such that dispensing operation of the spout and incrementing operation of the counter are synchronised.
