Abstract: An injection device includes: a housing with a product container in which a stopper with a bearing face can be moved to a stopper end position and which, proximally to the stopper end position, has a minimum product container cross section; a drive configured to move the stopper, which includes a plunger rod with a drive face that contacts the bearing face; a plunger rod guide is arranged outside the product container and guides the plunger rod, with a plunger rod guide cross section adapted to a plunger rod cross section. The product container only incompletely guides movement of the plunger rod and the plunger rod cross section is not prevented from moving in a tilting direction by the minimum product container cross section, and a plunger rod centering aid a distal end of the plunger rod limits the movement of the plunger rod in the tilting direction.

Abstract: An apparatus and method for adjusting an injection device for administering a substance that includes a device housing with an array of fastening points. The apparatus has at least two housing-like shells, each having at least one holding device and at least one blocking device for attaching to the housing. The holding device of a first shell can be attached to a fastening point, and the holding device of a second shell can be attached to a further fastening point. Upon attaching all of the plurality of housing-like shells to the housing, the blocking devices of the plurality of housing-like shells prevent the disengagement of the plurality of housing-like shells from the housing by blocking detachment of the holding devices from the fastening points. At least one of the housing-like shells comprises an electronic assembly and shell attachment to the housing activates the electronic assembly.

Abstract: The invention relates to a detachable needle protection cap for injection devices and to a method for producing same. The detachable needle protection cap comprises a housing and at least two shell parts which can be attached to an outer surface of the housing, the shell parts being fastened to an outer surface of the housing. The shell parts can mutually prevent removal of the shell parts.

Abstract: An injection device comprising a cap for removing a needle protection cap from a product container, and a method for assembling an injection device. The cap comprises an engaging element for removing the needle protection cap from the product container when the cap is removed from the injection device. The engaging element can be deformed in such a way that the engaging element can be moved from a distanced position, in which the engaging element is radially distanced from the needle protection cap, into an engagement position, in which the engaging element engages with the needle protection cap, with the engaging element being deformed when the cap is removed.

Abstract: An injection device includes: a housing with a product container in which a stopper with a bearing face can be moved to a stopper end position and which, proximally to the stopper end position, has a minimum product container cross section; a drive configured to move the stopper, which includes a plunger rod with a drive face that contacts the bearing face; a plunger rod guide is arranged outside the product container and guides the plunger rod, with a plunger rod guide cross section adapted to a plunger rod cross section. The product container only incompletely guides movement of the plunger rod and the plunger rod cross section is not prevented from moving in a tilting direction by the minimum product container cross section, and a plunger rod centering aid a distal end of the plunger rod limits the movement of the plunger rod in the tilting direction.

Abstract: An adjustable injection device for administering a substance includes a housing with an array of fastening points and at least two housing-like shells, each having at least one holding device and at least one blocking device for attaching to the housing. The holding device of a first shell can be attached to a fastening point, and the holding device of a second shell can be attached to a further fastening point. The holding device of the first shell is prevented from disengagement therefrom by the blocking device of the second shell, and the holding device of the second shell is prevented from disengagement therefrom by a blocking device of a further shell, or, in the event that the injection device has only two shells, is prevented from disengagement from the further fastening point by a blocking device of the first shell whereby the shells are non-detachably connected to the housing.
