Coca-Cola has changed the neck of its 1,5 litre PET bottle drastically over the past few years. 

The company has adopted a new neck finish weighing 1 gram less per bottle than the previous model, thanks to the improved design of the screw thread, the vertical grooves (which allow any excess pressure to escape upon opening) and the neck support ring (the spot where the machines grab the bottle during the shaping and filling processes).

The cap itself has also been improved in order to prevent waste: the additional plastic stopper ring that used to be located inside the cap has been removed without any adverse effect on sealing.
