Dispensing apparatus for delivering metered doses of product from a pressurised dispensing container comprises a housing for receiving a dispensing container and a dose counting mechanism comprising indication means for displaying to a user an indication associated with the number of doses dispensed from, or the number of doses remaining in, the dispensing container. The dose counting mechanism further comprises an indexing mechanism for advancing the indication means on actuation of the dispensing container wherein the dispensing apparatus comprises first and second indexing members 178 and 175 wherein movement of the received container in a first direction causes the first indexing member 178 to advance the indexing mechanism by a partial increment and also causes a strain to be imparted on the second indexing member; wherein subsequent movement of the container a second direction allows the second indexing member to move the indexing mechanism to complete the incremental advancement of the indexing mechanism by recovery of the imparted strain. |
