Abstract:
1. An injection device comprising: a housing, a cartridge arranged relative to the housing and defining a main axis, the cartridge comprising an outlet covered by a cartridge septum adapted to be pierced by an injection needle for establishing fluid communication with a cartridge interior and comprising a piston which is driveable along the main axis towards the outlet, a piston driver for engaging the piston and capable of being actuated for driving the piston in a distal direction towards the outlet, a needle assembly arranged at the distal end of the housing, the needle assembly comprising the injection needle having front and rear sections for respectively penetrating skin of a subject user and for piercing the cartridge septum, the needle assembly further comprising a needle container accommodating the injection needle, the needle container having an opening which in a storage state of the injection device is sealed by a film seal for maintaining the injection needle in a sterile condition, and a cover arranged relative to the housing and configured for relative movement, wherein, in the storage state of the injection device, the cover is held relative to the housing in a first relative orientation wherein the cover at least partly covers the needle assembly, wherein the cover at least in part forms a packaging which in the storage state of the injection device accommodates the housing of the injection device, and the cover defines a first cover section which swivels relative to the housing along a second axis, the second axis being substantially orthogonal to the main axis, wherein the injection device defines an unsealing member which is adapted to cause the film seal to change from a sealing state into an unsealing state by relative movement between the needle assembly and the unsealing member, wherein the first cover section forms a lever arm which upon operation causes the needle assembly and the unsealing member to move relative to each other, and wherein relative movement between the cover and the housing from the first relative orientation to a second relative orientation causes the film seal to change from the sealing state to the unsealing state for shifting the injection device into a ready-to-administer state, the cover being continuously coupled with the housing during said relative movement between the cover and the housing from the first relative orientation to the second relative orientation.
