ABSTRACT:
A discharge apparatus, or medium dispenser, has an annular contact surface, face or edge for contacting a surface or object to be sprayed by a medium dispensed from a discharge nozzle spaced therefrom. The contact surface, face or edge can, for example, engage the eye socket around the eye of a patient, the eyelids being eccentrically widened by pressure loading. The contact surface, face or edge is located at the end of the jacket of a cap body into which the medium is discharged by the nozzle. The jacket elastically gives way over part of its length by reason of transverse openings on its circumference and/or bottom. The openings permit a locally, precisely defined incidence of light on the area to be sprayed, and provide non-uniform stiffness.
