Abstract
A functional head for a fragrance container includes a housing wall section and a spring-loaded valve plate. The housing wall section has an inlet opening for admitting air into an inlet channel, an outlet opening for discharging a mixture of fragrance and air from an outlet channel, and a recess. The valve plate is biased to close the openings and is displaceable by a plunger inserted into the recess to thereby open the openings.
