Abstract: A breath actuated metered dose inhaler including a housing, a canister and a trigger mechanism. The trigger mechanism is activated by the inhalation of air which comprises of a diaphragm. The central rigid disk of the diaphragm is provided with the interlocking means to firmly secure and bound the peripheral flexible polymer ring with the central rigid disc. The mechanical interlock between a central rigid disk and a peripheral flexible polymer ring on the diaphragm prevent peripheral flexible polymer ring from being peeled off from the central rigid disc while the vacuum is being retained prior to inhalation.
