Abstract
A plastic ampoule includes a container (12) for receiving a defined fluid, with a neck (14) that can be closed by a head (16). The neck has a channel-type entrance port (24) for air to the interior (26) of the container (12). The fluid can be safely stored and a syringe or needle base is reliably filled at any speed of withdrawal by the syringe or needle base. For this purpose, the entrance port (24) for air includes at least one ring channel (28, 30) that is at least partially disposed on the outer and/or inner periphery of the neck (14).
