The invention relates to a plastic ampoule which comprises a container (12) for receiving a defined fluid. Said container is provided with a neck (14) that can be closed by means of a head (16), the neck comprising a channel-type entrance port (24) for air to the interior (26) of the container (12). The aim of the invention is to improve the generic ampoule types in such a manner that the fluid can be safely stored and the syringe or needle base is reliably filled at any speed of withdrawal by means of the syringe or needle base. For this purpose, the entrance port (24) for air consists of at least one ring channel (28, 30) that is at least partially disposed on the outer and/or inner periphery of the neck (14).

L'invention est caractérisée en ce que la zone d'entrée (24) d'air est composée d'au moins un canal annulaire (28,30) disposé au moins partiellement au niveau du pourtour extérieur et/ou intérieur contre le col (14). La présente invention améliore les formes d'ampoules connues par la création d'une réserve sûre de fluide, un remplissage fiable de ces ampoules étant en outre réalisé, quelle que soit la vitesse de prélèvement du fluide au moyen d'une seringue ou d'une canule.
