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.

Claims

1. A noise tamper evident cap assembly for a medical injection device comprising:

a sleeve assembly comprising at least one side wall, said side wall forming circumferentially around a tip cap, and being permanently affixed to a bottom cap,

at least one noise fin formed along an interior of said at least one side wall, and disposed in at least partially obstructing and overlying relations relative to a bottom portion of said tip cap,

said tip cap being removably connected to said bottom cap via an engagement mechanism, said bottom portion of said tip cap interacting with said at least one noise fin upon removal of said tip cap from said sleeve assembly creating an audio indicator to a user, and

said bottom cap structured and dimensioned to enclose a dispensing portion of the medical injection device.

2. The noise tamper evident cap assembly of claim 1 wherein said noise fin(s) are structured and configured to vibrate the surrounding air in order to create an audible indicator, upon the removal of said tip cap from said bottom cap.

3. The noise tamper evident cap assembly of claim 1 wherein said tip cap further comprises an engagement flange that cooperative engages with said bottom cap via said engagement mechanism.

4. The noise tamper evident cap assembly of claim 3 wherein said engagement mechanism comprises the removable engagement of least one tip cap engagement member with at least one bottom cap engagement member.

5. The noise tamper evident camp assembly of claim 3 wherein said noise fin(s) are structured and configured to vibrate the surrounding air in order to create an audible indicator, upon the resulting interaction between said engagement flange and said at least one noise fin.

6. The noise tamper evident cap assembly of claim 1 wherein said bottom cap is permanently affixed to an apical portion of the medical injection device.

7. The noise tamper evident cap assembly of claim 1 wherein said noise fins are angled upwards relative to a base of the medical injection device, such that said tip cap is unable to pass back through said noise fins after removal.

8. The noise tamper evident cap assembly of claim 7 wherein said noise fins are structured and configured in at least partially obstructive relations relative to a portion of said engagement mechanism formed on said bottom cap.

9. The noise tamper evident cap assembly of claim 7 wherein said noise fins are structured and configured in fully obstructive relations relative to a portion of said engagement mechanism formed on said bottom cap.

10. A noise tamper evident cap assembly for a medical injection device comprising:

a sleeve assembly comprising a side wall formed circumferentially in surrounding relations relative to a tip cap, and being permanently affixed to a bottom cap

said side wall including at least one noise fin protruding along an interior thereof, and disposed in an upward angle,

said at least one noise fin further disposed in at least partially obstructing relations relative to an engagement flange of said tip cap,

said tip cap being removably connected to said bottom cap via an engagement mechanism, and

said bottom cap structured and dimensioned to enclose a dispensing portion of the medical injection device.
