Dispenser and method for discharging media
First Claim
1. Dispenser for at least one medium comprising:
- a pump (19) operable for dispensing the medium in consecutive dispensing strokes, the pump having an inlet (20) connected to a source (13) of said medium and an outlet connected to a discharge opening (14), and the pump requiring for priming at least one priming stroke;
a protective cap (38) being provided to cover at least the discharge opening (14) before use, said cap being removable to uncover the discharge opening (14) and to allow the dispensing strokes; and
locking means for ensuring said at least one priming stroke with the protective cap fitted on the dispenser, and before removal of said protective cap to allow the dispensing strokes.

Abstract
In a dispenser, particularly an atomizer, which is used for flowable substances, particularly pharmaceuticals, use is made of a pump, which must be actuated one or more times for priming purposes. Its discharge nozzle (14) is covered by a protective cap (38), which is suitable to collect and store the medium, which is discharged during the priming strokes and before the start of the useful strokes. During the priming strokes the protective cap (38) is secured on the dispenser (11). This is brought about in that a locking (40) for the protective cap is only released when the priming strokes have been performed. This can take place by electrical actuation or by material change under the influence of the medium to be discharged. According to a variant the protective cap is not itself locked, but an actuation locking takes place if the protective cap has not been fitted for the priming strokes.
