Abstract
A protective cap comprises closure elements, by the operation of which the narices can be closed for the purpose of pressure equalization in the middle ear in overcoming extreme differences in altitude. To be able to execute the operation without visual impairment, it is provided that the closure elements are designed as motion elements variable in their extent, which are connected to a flow medium contained in feed lines which is pressurized by an operating element displacing the flow medium.
