Abstract
A dispensing mechanism for a liquid container is arranged in liquid communication with an outlet mechanism. The dispensing mechanism is adapted to translate a user force applied to a user operated portion into a transfer force applied from a user lever to an actuation part. A relationship between a first length and a second length forms a lever ratio. The first length extends from a first pivot axis to a user operated portion and the second length extends from the first pivot axis to a point of action of the transfer force on the actuation part. The lever ratio is adapted to increase from a non-actuated position over at least the first 50% of a dispensing stroke of the actuation part such that the transfer force increases over the at least first 50% of the dispensing stroke when a constant force is applied to the user operated portion.
