Abstract: A discharge head for a dispenser including a base and an applicator mounted movably thereon. The base is fitted onto a liquid reservoir or is rigidly integrated on a liquid reservoir. The applicator includes a discharge opening through which liquid is released into an environment. The discharge head includes a pump mechanism or a valve mechanism arranged in a liquid channel connecting the liquid reservoir to the discharge opening. The pump mechanism is actuated by displacement of the applicator relative to the base, or the valve mechanism is opened and closed by displacement of the applicator relative to the base. The discharge head includes a cap unit with a cap for covering the discharge opening and a separate securing portion mounted securely on the base or the applicator via a securing mechanism and is designed to secure the cap releasably.

Abstract: Liquid dispenser for discharging pharmaceutical liquids, having a housing, an outlet opening and an outlet valve assigned to the outlet opening. The outlet valve includes a pressure chamber arranged upstream of a valve opening and delimited to one side by a valve plate of a valve body. By increasing the pressure in the pressure chamber, the valve can be opened. The pressure chamber has a flat form and has a large surface area in contact with liquid in relation to the volume.At least one portion of the valve plate which is in contact with liquid in the pressure chamber is of a valve plate material produced using metallocenes as catalysts.
