Patent ID: 8689785

Claim:
Dispensing apparatus for delivering metered doses of product from a pressurised dispensing container comprising: a housing for receiving a pressurised dispensing container; a dose counting mechanism comprising indication means for displaying to a user an indication associated with the number or quantity of doses dispensed from, or the number or quantity of doses remaining in, the received pressurised dispensing container; the dose counting mechanism further comprising an indexing mechanism for advancing the indication means on actuation of the received pressurised dispensing container; wherein the dispensing apparatus comprises first and second indexing members which together act to incrementally advance the indexing mechanism on actuation of the received pressurised dispensing container; wherein the indexing mechanism comprises a first set of abutment surfaces for engagement with the first indexing member and a second set of abutment surfaces for engagement with the second indexing member; wherein movement of the received pressurised dispensing container in a first direction relative to the indexing mechanism causes the first indexing member to advance the indexing mechanism by a partial increment by engagement of the first indexing member with the first set of abutment surfaces and also causes a strain to be imparted on the second indexing member; wherein subsequent movement of the received pressurised dispensing container in a second direction, opposed to the first direction, allows the second indexing member to move the indexing mechanism by engagement with the second set of abutment surfaces to complete the incremental advancement of the indexing mechanism by recovery of the imparted strain.
