Method and device for nondestructively testing fluid-filled containers for leaktightness

The invention relates to a propellant-free inhaler which has a storage chamber (6) for a powdered substance to be inhaled, which is associated with a metering device (8), which is manually operated by means of a button, having a metering chamber (7) for receiving a given dose of the powdered substance. The device also has a lateral mouth piece (11) for active breathing in, with an air channel (7) for distributing the particular dose of the powdered substance in the air stream. To ensure that the dosage provided is highly reproducible, a high proportion of this dose leaves the inhaler and the medicinal substance is reproducibly dispersed, a trigger operated pump (12,19,20) is provided which can be manually primed before the inhalation process by means of a button (1,42) and which can be actuated in synchronism with the breathing, thereby generating a current of foreign air which disperses the metered substance.
