  • Patent number: 9592351
    Abstract: A medicament delivery device is presented having a housing configured to receive a medicament container having a delivery member and a shield, a protective cap, and wherein the protective cap comprises connecting means for connecting to the shield of the medicament container such that removal of the protective cap from the housing causes removal of the shield from the medicament container. The delivery device is characterized in that a protective cap assembly has a first disconnecting means configured to interact with corresponding second disconnecting means of the housing and of the protective cap such that activation of the first disconnecting means of the protective cap assembly causes the displacement of the protective cap relative to the housing.

  • Patent number: 8876766
    Abstract: A medicament delivery device includes a housing with a circle-segment-shaped compartment for a drive unit that moves at least one stopper in a medicament container and that includes a support wheel and central hub on which first and second parallel disks are fixedly attached and interconnected by an abutment cross-wall; spherical members between the abutment wall and adjacent the stopper; a clock spring within the hub with an outer end connected to the hub and an inner end connected to a one-direction-rotatable tubular hub coaxially arranged around a shaft fixedly attached to a housing part; and an activation member connected to the first disk by a hold-and-release mechanism. When the activation member is not depressed, the wheel and spring are held in a tensioned static state, and when the activation member is depressed, the spring and wheel are released and the spherical members are forced against the stopper.
