A dispensing device having a storage device and an air pump for dispensing a medical formulation. The storage device has multiple inserts, each insert containing a single dose of the formulation. Each insert is located in a separate and sealed cavity. The cavities can be individually opened for dispensing the respective dose from the respective insert by movement of the respective insert through the seal, so as to break the seal only at one side of the outlet opening so that the seal is pivoted mainly to an opposite side of the outlet opening by the movement of the insert for minimizing potential interference by the opened seal with flowing of the formulation from the receptacle toward the mouthpiece.
