A device for dispensing a substance in fluid or powder form, the device having a dispensing outlet ( 10 ), an air blaster ( 20 ) for generating a blast of air when the device is actuated, and at least one reservoir ( 30 ) containing a single dose of substance. The reservoir ( 30 ) an air inlet ( 31 ) connected to the air blaster ( 20 ), and a substance outlet ( 32 ) connected to the dispensing orifice ( 10 ), the air inlet ( 31 ) being provided with a substance retaining member ( 40 ) for retaining the substance in the reservoir ( 30 ) until it is dispensed, and the substance outlet ( 32 ) being closed off by a closure element ( 50 ). The dispenser device is configured such that the closure element ( 50 ) is a spherical element, such as a ball, force fitted into the substance outlet ( 32 ) of the reservoir ( 30 ). The device further has a mechanical opening system ( 60, 70, 80 ) co-operating with the closure element ( 50 ) for ejecting it mechanically from its closure position when the device is actuated.
