Abstract

A device for storage and transportation of an empty case of a firearm bullet cartridge for forensic investigation, wherein said case comprises a cylindrical shell which is substantially closed at one end, said device comprising a container having a bottom wall, a side wall and an opening, and comprising a cap for sealing the opening of said container, wherein said cap is provided with holding means arranged to be inserted in the empty case for restricting lateral movement of the empty case in said container.

First claim

1 . A device for storage and transportation of an empty case of a firearm bullet cartridge for forensic investigation, wherein said case comprises a cylindrical shell which is substantially closed at one end, said device comprising:
a container having a bottom wall, a side wall and an opening; a cap for sealing the opening of said container, wherein the cap includes a holding means arranged to be inserted in the empty case for restricting lateral movement of the empty case in said container.

2 . The device of claim 1 , wherein said holding means includes a pin.

3 . The device of claim 1 , wherein said holding means includes a clamping means for clamping the closed end of said empty case against the bottom wall of the container.

4 . The device of claim 3 , wherein said clamping means includes a pin which is arranged to be inserted into the empty case and which pin is arranged to be pushed against said bottom wall.

5 . The device of claim 4 , wherein said pin extends from the center of said cap.

6 . The device of claim 5 , wherein said pin is provided with a resilient part.

7 . The device of claim 6 , wherein said resilient part comprises a spring.

8 . The device of claim 7 , wherein said resilient part is compressible by at least 3 mm and, preferably, by at least 5 mm.

9 . The device of claim 7 , wherein said resilient part extends from the cap and the pin extends from the resilient part.

10 . The device of claim 1 , wherein the container is provided with at least one ventilating hole with filter means that shut off the interior of the container from contamination from the environment.

11 . The device of claim 10 , wherein said ventilating hole is provided in the cap.

12 . The device of claim 1 , wherein the container is a tubular container.

13 . The device of claim 1 , wherein said cap is provided with a screw thread for fixing the cap to the container.

14 . The device of claim 1 , wherein the container has a length of 3-5 cm and, preferably, a length of 3.5-4.5 cm.

15 . The device of claim 1 , wherein the container has a diameter of 2-3 cm and, preferably, a diameter of 2.3-2.8 cm.

16 . The device of claim 2 , wherein said pin has a diameter of 0.3-0.4 cm and, preferably, a diameter of 0.33-0.37 cm.

17 . The device of claim 2 , wherein the distance between the outer side surface of the pin and the inner surface of the side wall of the container extending on the opposite side of the pin is 0.8-1.7 cm and, preferably, is 1.0-1.5 cm, and more preferably, is 1.1-1.3 cm.

18 . The device of claim 1 , wherein said bottom wall of said container is provided with ribs for maintaining a distance between the surface of said bottom wall and the closed end of the empty case.

19 . The device of claim 1 , wherein said cap is provided with ribs on its outer end wall for maintaining a distance between the ventilating hole and a surface on which the outer end wall of the cap is placed.

20 . A method for storage and transportation of an empty case of a firearm bullet cartridge for forensic investigation, said method comprising:
providing a container having a bottom wall, a side wall and an opening; providing a cap attached to the container for sealing the opening of said container, said cap includes holding means inserted in the empty case for restricting lateral movement of the empty case in said container when the cap is attached to the container.
