Claim 0:
1. A discharger for discharging a predetermined amount of fluid, comprising:
a sleeve 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 including a receiving space disposed therein, the receiving space configured to have the fluid disposed therein, the carriage cooperating with the proximal end of the sleeve such that the carriage is moveable relative to the sleeve along the longitudinal first axis to expel the fluid from the receiving space; and
a piercing tip having a flow channel configured to establish 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, the piercing tip being integrally formed with at least a portion of the sleeve or formed as a unitary separate piece linked with at least the portion of the sleeve, the shell surface of the piercing tip having an essentially convexly curved configuration, and the sleeve surrounding a proximal end of the discharge section and having an outer diameter that is substantially the same as the inner diameter of the carriage.
