Abstract: The closure stopper and the elastic retaining element are made of gas-permeable material, so that sterilizing gases can penetrate by permeation. The closure stopper is formed of a pharmaceutical rubber. In one variant, the closure stopper, the retaining element and the protective element are made in one piece, with longitudinally extending gas delivery slits arranged between the protective element and the closure stopper.

Abstract: The closure stopper (3) and the elastic retaining element (5) are made of gas-permeable material, so that sterilizing gases can penetrate by means of permeation. The closure stopper (3) consists of a pharmaceutical rubber. In one variant, the closure stopper (3), the retaining element (5) and the protective element (7) are made in one piece, with longitudinally extending gas delivery slits (33) arranged between the protective element (7) and the closure stopper (3).

Abstract: Claimed and disclosed is a dropper, preferably an eye dropper having a detached edge area wherein a dropper insert is arranged at a dropper tip. At this detatched edge area, the dropper tip is either flushed with the frontal extremity of the dropper insert or recessed relative to the frontal extremity of the dropper insert. This dropper facilitates the dispensing and the delivery of small droplets with precise pre-determined volume from the dropper to an eye with reduced risk of injury to the eye during application of the droplets.

Abstract: The invention relates to a needle guard assembly for the needle part of a syringe body in the form of a needle guard that covers the needle and which is displaceable on the syringe body in the longitudinal direction, and with a grip plate being integrally formed on that end of the syringe body remote from the needle. The needle guard assembly includes a syringe body ending with a needle. A piston rod in the syringe body has a receiving part and a push-in part that telescopes into the receiving part. A syringe-body grip plate is integrally formed on the syringe body. The syringe-body grip plate opposes the needle. A needle guard is arranged longitudinally along the syringe body and covers the needle when the needle guard is displaced longitudinally.
