Title: DISCHARGER WITH IMPROVED PIERCING TIP
Abstract:
The present invention relates to a discharger for discharging a predetermined amount of fluid and to a discharge system comprising the discharger. The discharger comprises a housing defining a longitudinal first axis and having a proximal end and a distal end, a discharge section having a discharge passage for the fluid extending between an inlet opening and an outlet opening of the discharge section, a carriage cooperating with the proximal end region of the housing such that the carriage is moveable relative to the housing along the first axis, the carriage comprising a receiving space for the fluid, and a piercing tip having a flow channel for establishing a flow connection for the fluid from the receiving space to the inlet opening of the discharge section, the piercing tip defining a centrally extending longitudinal second axis and having a shell surface, wherein the shell surface of the piercing tip has an essentially convexly curved, in particular dome- shaped, configuration. The discharge system further comprises a container holding an amount of fluid and being adapted to be loaded into the receiving space of the carriage.
