The housing 4,5 receives, in use, a container of product 10. Each actuation of the apparatus causes a first annular member 11 to incrementally rotate which, after a predetermined number of actuations, causes the cog 12 to rotate and the rotation of the cog 12 causes a second annular member 13 to rotate. The annular members 11,13 can have markings to indicate the amount or number of doses of product dispensed or remaining in a container 10 received within the apparatus 1. The cog 12 comprises a hub with a hole 53 at the centre and has a plurality of teeth 50,51,52 extending from the centre, one or more of the teeth are of a reduced height 50,52 in the direction of the longitudinal axis through the central hole 53.
