The old model was fleeing, not this one. or it's rare. The former could not move because otherwise other than flat water flowed through the spout in the plastic covering, and from there everything was flowing into the bag. This one has a small transparent accessory below the spout will not spill it during transport. It is possible to drink with this cap in place but for an older child because you have to suck harder. The only downside is that to remove this tip unscrew the lid and put hands! not very convenient ride when no super clean hands: - /. But still I recommend my son who refuses the bottle from its six months qua swears by it. Removable handle also :-)
