SELF-DRIVEN MEDICAMENT CONTAINER AND MEDICAMENT DELIVERY DEVICE

A self-driven medicament container (10, 10') for storing and discharging a medicament in response to a user interaction is provided, the self-driven medicament container (10, 10') comprising: a reservoir body (2), a retainer (3), a stopper (4) configured to divide an interior of the reservoir body (2) into a drive compartment (21) and a medicament compartment (22), the medicament compartment (22) containing the medicament and comprising an outlet (23) through which the medicament can be discharged in a dispensing operation. The self-driven medicament container (10, 10) further comprises a drive element (5), a plunger having a shaft (61, 6T) with a locking element (62, 62') configured to engage the retainer (3) to prevent a distal movement of the plunger relative to the reservoir body (2) and a contact element (63) configured to contact the stopper (4), and a release mechanism, configured to disengage the locking element (62, 62') from the retainer (3) in response to the user interaction thereby enabling a distal movement of the plunger relative to the reservoir body (2). The medicament compartment (22) is distal to the drive compartment (21). The stopper (4) is further configured to seal the medicament compartment (22) relative to the drive compartment (21). The drive element (5) is positioned in the drive compartment (21) before and after the locking element (62, 62') is disengaged from the retainer (3). The drive element (5) is configured to provide an axial force to the plunger in order to move the plunger distally relative to the reservoir body (2) thereby moving the stopper (4) relative to the reservoir body (2) and discharging the medicament, when the locking element (62, 62') is disengaged from the retainer (3). Further there is provided a medicament delivery device (100, 100') comprising said self-driven medicament container. L'invention concerne un contenant de médicament à propulsion automatique (10, 10'), destiné à stocker et libérer un médicament en réponse à une interaction d'utilisateur, le contenant de médicament à propulsion automatique (10, 10') comprenant : un corps de réservoir (2), un dispositif de retenue (3), un bouchon (4) conçu pour diviser l'intérieur du corps de réservoir (2) en un compartiment de propulsion (21) et un compartiment de médicament (22), le compartiment de médicament (22) contenant le médicament et comprenant une sortie (23) à travers laquelle le médicament peut être libéré dans un actionnement de distribution.
