摘要

AUTOMATIC INJECTION DEVICES HAVING OVERMOLDED GRIPPING An injection device (100), comprising: a first body portion (116); a second body portion (118) cooperatively engageable to the first body portion (116) to form a grasping region of the device (100) at a proximal portion thereof and to define an injection region of the device at a distal portion thereof, a first overmolded gripping surface (154) disposed along a first length of the gripping region; a second overmolded gripping surface (156) disposed along a second length of the gripping region opposite the first overmolded gripping surface (154); a first recessed portion (122) abutting the first overmolded gripping surface (154); a second recessed portion (124) abutting the second overmolded gripping surface (156); a firing button (12) that extends from a recessed surface of the first body portion (116); an inspection window (128) disposed in the injection region to allow a user to view a content of a container disposed within the injection device (100); a removable cap (164) couplable to the distal portion of the device (100), the removable cap (164) having a concave cutout portion for accommodating part of the inspection window; and a third overmolded gripping surface disposed over an exterior surface of the removable cap (164).
