Abstract: The invention relates to a method for keeping the dispensing parts on a device for administering a sterile preparation for local treatment containing a preservative-free preparation free from bacterial growth. This is achieved in that the dispensing part is allowed to dry quickly after each use. The invention is also directed towards a cap to be used in this method.

Abstract: A device for dispensing a liquid, sterile, preservative-free preparation free from bacterial growth. The device includes a reservoir which contains the preparation and, in fluid communication with the reservoir, a dispensing part constructed to deliver the liquid preparation directly to a predetermined region of the human body. The device also includes a protective cap constructed to be removably mounted over the dispensing part, where the protective cap has an opening which allows ambient air to reach the dispensing part to facilitate air-drying of the dispensing part. Located near the opening is a plug constructed from an absorbent material, such as ethylenevinylacetate foam or sintered polyethylene, which helps the dispensing part dry quickly.
