Cap for scuba tanks with bushing for fastening by cord or bungee and air outlet channels

Cap for scuba tanks with hole for fastening with cord or bungee and air outlet channels With the caps I differentiate the filled diving bottles from the unfilled ones. All not ready to dive bottles have no marking. So a mix-up in case of accidental loss is not a problem. In the middle I have placed a large dimensioned feed-through. With it I fix the cap captive to the diving bottle. The knot can be stored comfortably in the inside. Furthermore the large dimensioned feed-through is also used for pressure compensation. This is an enormous advantage if the bottle is accidentally opened while the cap is screwed on. In addition, the cap will probably not fly through the room like a projectile, because please keep in mind that the cap is not made of metal. Additionally I implemented 9 more hidden air channels for pressure equalization.
