Abstract
A noise tamper evident cap assembly for a medical injection device is provided. The assembly includes a sleeve assembly having a sidewall formed circumferentially around a tip cap, and being permanently affixed to a bottom cap. At least one noise fin is formed along an interior of the side wall and disposed in at least partially obstructing and overlying relations relative to a bottom portion of said tip cap, such that the removal of the tip cap will cause an interaction with said noise fin(s) and create an audible indicator. The tip cap is removably connected to the bottom cap via an engagement mechanism, which is also obstructed by the noise fin(s). The bottom cap is structured and dimensioned to enclose a dispensing portion of the medical injection device.
