Patent ID: 8251056

Claim:
An inhaler for use with a container unit containing a medicament formulation to be dispensed, comprising: a housing for the container unit and in which the container unit is relatively movable thereto to cause dispensing of a dose of the medicament formulation from the container unit for inhalation by a user through a dispensing outlet of the inhaler; a closure movable between a closed position, in which the closure closes the dispensing outlet, and an open position, in which the dispensing outlet is open; and a revolvable element comprising a restricting member, the revolvable element in use being revolvable around an axis between a first position, which places the restricting member in a non-restricting position which does not restrict relative movement between the container unit and the housing for dispensing of the dose of the medicament formulation, and a second position, which places the restricting member in a restricting position which does restrict relative movement between the container unit and the housing such that dispensing of the dose of the medicament formulation is prevented; wherein the closure is associated with the revolvable element such that movement of the closure from the closed position to the open position causes the revolvable element to move the restricting member from the restricting position to the non-restricting position and vice-versa; and wherein a hinge is disposed between the revolvable element and the closure, so that the closure is hingably movable relative to the revolvable element, wherein the closure is able to be hinged relative to the revolvable element towards the restricting member, and wherein the hinge allows the revolvable element and the closure to be hinged into facing relationship when the closure is in its open position so that the restricting member is covered by the closure.
