摘要:
A discharge head for the nasal application of pharmaceutical liquid from a pressure reservoir which has an outlet valve with a valve connector, to which force can be applied counter to a spring force in order to open the outlet valve. The discharge head has a nasal applicator which extends outward from an actuating surface and at the end of which a discharge opening is provided. The discharge opening is connected in a fluid-communicating manner to a hollow tube through an applicator channel of the nasal applicator, for connection to the pressure reservoir. The nasal applicator has an inner component connected integrally to the actuating surface and an outer component separate from the inner component and attached to the inner component in a surrounding manner. The discharge opening is provided in the outer component, and the outer component and the inner component together bound the applicator channel.
