摘要： A double-walled container includes a top opening, and a bottom opening, opposite the top opening. A removable top cap engages with threads at the top opening and a removable bottom cap engages with threads at the bottom opening. The double-walled container includes an outer wall and an inner wall. A channel formed on and encircling the outer wall includes a vacuum port through which air between the outer and inner walls is drawn out to form an insulating space between the inner and outer walls. A band is positioned within the channel to cover the vacuum port.

摘要： A compact silencer device for a firearm comprising of multiple chambers which trap the gases from a projectile exiting the barrel of a gun to slow down the gases and reduce the temperature, sound, and flash associated with the projectile. In one embodiment, the first chamber which attaches to the barrel of the firearm comprises of sound baffling materials or gas porting baffles which vent gases from the second chamber passing rearward. The second chamber comprises of a chamber which can accommodate a retractable third chamber of the device, the second and third chamber of the device can have sound baffles to slow down the gases from the projectile.
