MOUNTING ARRANGEMENT AND COUPLING ASSEMBLY FOR A DRUG-DELIVERY DEVICE

摘要

A mounting arrangement for a drug-delivery device is proposed, the mounting arrangement comprising: a plug element with a longitudinal axis (L) and a housing part having a recess with a side wall which is adapted to receive the plug element. At least one of the plug element or the side wall of the recess are provided with a protrusion for fixing the plug element in a given position relative to the housing part by a force-fit engagement. Furthermore, a coupling assembly is proposed, the coupling assembly comprising the plug element and the housing part being mechanically coupled to each other.

1. A pen-type drug injection device comprising:
a housing having a longitudinal axis and a recess with a side wall comprising a deformable protrusion positioned parallel to the longitudinal axis; a hollow cylinder; and a cartridge holder configured to stabilize the hollow cylinder, wherein the hollow cylinder is mechanically coupled within the recess by a force fit contact with the protrusion, where a friction force is caused by a deformation of the protrusion when the hollow cylinder is coupled to the housing.
