The ring helps to hold the bottle with one hand. My wife complained, that the sodastream bottle is hard to hold with one hand, since it is rather thick and unhandy at the bottle belly. This inspired me to design the ring.

The ring consists of three parts and after mounting, it will stay safe and stable without any wobbling at the bottle neck.

For cleaning the bottle , the ring can be removed.

For carbonating inside the sodastream crystal device, the ring may stay in place, so removing the ring is only necessary, if intensive cleaning is desired.

A little filing at the connection points may be required. The fixing ring that goes over the two ring halfs to fix them in position shout have a snug fit, so it does not come off for its own. The slots in the ring halfs underneath the fixing ring are intended to be able to lift off the fixing ring using a screw driver blade if intensive cleaning is desired. The two ring segments should be mounted, so the groove of the inner diameter surrounds the embossed collar of the bottle neck.
