Discharger
First Claim
1. A discharger for discharging a predetermined amount of fluid, the discharger comprising:
- a housing defining a longitudinal axis and having a proximal end and a distal end;
a discharge device partly arranged inside the housing and having an inlet opening situated inside the housing and an outlet opening situated outside the housing, the discharge device further defining a discharge passage for the fluid extending between the inlet opening and the outlet opening;
a carriage received in a proximal end region of the housing and being moveable relative to the housing along the longitudinal axis between a starting position and a final discharge position,in the starting position, the carriage protruding from a proximal end of the housing so as to be pushable by a user further into the housing and towards the final discharge position, andthe carriage defining a receiving space configured to be loaded with a separate container holding an amount of fluid to be discharged; and
an activation device configured to establish a flow connection for the fluid from within the receiving space of the carriage to the inlet opening of the discharge device, the activation device being inoperative when the carriage is in the starting position and with the activation device being configured to establish the flow connection when the carriage is in the final discharge position or is being moved towards the final discharge position, the discharger configured to discharge the fluid inside the container through the discharge device by a discharging action, the discharging action comprising pushing the carriage and the container into the housing simultaneously, and at least during the discharging action, a position of the discharge device is fixed with respect to the housing.

Abstract
A discharger for a fluid includes a housing having proximal and distal ends, a discharge device, the discharge device defining a passage between inlet and outlet openings, a carriage received in an end region of the housing and moveable relative to the housing between starting and discharge positions, in the starting position, the carriage protruding from the proximal end so as to be pushable into the housing and towards the discharge position, and the carriage defining a receiving space to be loaded with a separate container holding a fluid to be discharged, and an activation device configured to establish a flow connection for the fluid from within the receiving space to the inlet opening, the activation device being inoperative when the carriage is in the starting position and with the activation device establishing the flow connection when the carriage is in or being moved toward the discharge position.
