<p>The present invention provides dispensing apparatus for delivering metered doses of product from a pressurised dispensing container comprising:
a dose counting mechanism comprising an indexing mechanism for advancing an indication means on actuation of the received pressurised dispensing container,
wherein on actuation of the received pressurised dispensing container in a normal mode of operation an indexing member is able to interface with the indexing mechanism to apply a force to the indexing mechanism sufficient to incrementally advance the indication means;
wherein the eventuality that the indexing mechanism or the indication means is jammed so as to prevent advancement, the indexing member and the indexing mechanism are enabled to move relative to one another in such a way to allow the indexing member to bypass the indexing mechanism to allow actuation of the received pressurised dispensing container.</p> |
