The present disclosure is generally directed to a drug delivery device for selecting and dispensing a number of user variable doses of a medicament and to a housing for such a device. The housing comprises an outer housing with a distal end and a cartridge holder with a proximal end, which, when the cartridge holder is attached to the outer housing, is inserted into the distal end of the outer housing. The outer housing is provided with a first fixture for axially constraining a further component part to the outer housing. When the cartridge holder is attached to the outer housing, the proximal end of the cartridge holder axially extends to the first fixture.

A cartridge holder, which has a distal end and a proximal end, comprises a coupling housing portion in which a cartridge can be inserted at least partly. The coupling housing portion is configured to be coupled to a part of a drug delivery device. The cartridge holder further comprises a fixing member which is connected with the coupling housing portion. The fixing member is moveable radially inwardly to a position in which the fixing member is suitable for securing the cartridge against distal displacement of the cartridge.

A drug delivery device comprises a first component and a second component, wherein a substance is provided on at least one of the first component and the second component. An inner friction of the substance is great enough to stabilize at least one of the orientation and the position of the first component and the second component with respect to one another. The inner friction of the substance is small enough to allow relative movement of the first component and the second component necessary for the intended operation of the device. Furthermore, a method for assembling a drug delivery device is provided.

A dose setting mechanism for a medicament delivery device is presented having a pinion mounted to a locking member where the axis of rotation of the pinion is offset and parallel to the longitudinal axis of the housing containing the dose setting components. Primary and secondary dose members are engaged with the pinion to indicate a set dose of medicament.

The present invention relates to a medicament delivery device comprising: a housing (10, 16) having a distal and an proximal end, said housing being adapted to receive a medicament container (18) with a delivery member (20) or with a connectable delivery member for delivery of a medicament; a drive mechanism (54) arranged to act on a plunger rod (58), which plunger rod (58) in turn is arranged to act on the medicament container (18) for providing automatic delivery of the medicament; a release mechanism (62) interactively connected to the drive mechanism (54) for releasing the drive mechanism (54) from a pre-tensioned state; a signal generating mechanism (90) for generating an audible and/or tactile and/or visual signal indicating that the medicament has been completely delivered, which signal generating mechanism (90) is operably connected to said drive mechanism such that it is arranged movable in a longitudinal direction in relation to said drive mechanism (54), that said drive mechanism (54) is arranged with a signal release mechanism (111) capable of activating said signal generating mechanism (90) at a certain longitudinal position of said drive mechanism after its release, for generating an audible and/or tactile and/or visual signal, wherein said signal generating mechanism (90) comprises a signal delay mechanism (105) operably arranged to delay the generation of signal after activation of said signal generating mechanism (90).

An assembly for a drug delivery device comprises a housing, a dose member which is displaceable in a proximal direction with respect to the housing for setting of a dose of a drug, a clutch member which is displaced in the proximal direction with respect to the housing when setting the dose, and a stop member configured to define a clutch stop position. The clutch member and the dose member are configured to mechanically cooperate with one another when the clutch member is in the clutch stop position, thereby preventing further displacement of the dose member in the proximal direction with respect to the housing during setting of the dose.

A cartridge assembly (200) having a shared fastening features for use with a drug delivery device (202). The cartridge assembly includes a cartridge holder (204), a drug cartridge (206), and a connector (208). The connector may be attached to the drug cartridge. The cartridge assembly further includes a fastening means (210, 212) for fastening to a drug delivery device, and this fastening means is shared between the cartridge holder and the cartridge or between the cartridge holder and the connector. The drug delivery device may be a reusable drug delivery device or a disposable drug delivery device.

A pharmaceutical cartridge holding unit holds a pharmaceutical cartridge and is mounted to a pharmaceutical injection device main body in order to mount the pharmaceutical cartridge to a pharmaceutical injection device. The pharmaceutical cartridge holding unit comprises an outer peripheral cap having a distal end opening and a rear end opening, and a cartridge cover that is disposed on the inside of the outer peripheral cap and is held in a state of being able to slide forward and backward with respect to the outer peripheral cap. The outer peripheral cap has a guide component that guides the sliding of the cartridge cover forward and backward, stoppers that prevent the cartridge cover from coming loose from the outer peripheral cap, and protrusions that can engage with the pharmaceutical injection device main body.

According to the present invention, a packing member (20) is disposed between a mouth portion (2b) of a container body (2) and a lid base portion (5). A crushing protrusion (20b) which protrudes downward and is crushed to an upper end opening edge of the container body (2) is formed on a lower surface of the packing member (20). An overhang recess (20c) which is at least partially located just above the crushing protrusion (20b) is formed on an upper surface of the packing member (20). After the lid base portion (5), the movable lid portion (6) and the syringe tube (8) are detached from the container body (2), when mounting again, until a crushing protrusion (20b) is crushed, the packing member (20) forms a communication gap (30) between the mouth portion (2b) of the container body (2) and the packing member (20).

A medication delivery device and/or dosing mechanisms suitable for use in medication delivery devices, in particular in pen-type injectors, preferably having a dose setting system and a drive device enabling the administration of a medicinal product from a single- or multi-dose medication cartridge.
