Hi and welcome. I reckon it can safely be called a stoppered bottle.
I would think it's fairly recent, but it's unfortunately very difficult to make anything out from your photos.
Is there a "ridge" at the top of the blue part? - it looks as if it might have been partially cased in blue, over a white/clear bottom and top part.
That would make it a slightly more sophisticated thing than it being just a two colours of glass bottle.
There are loads of tips and techie info here for getting your pics right for posting to the board. I'm afraid some of yours are too out of focus to make any detail out.

That is much appreciated. If you get stuck, you can send them to me (click on the little envelope beside my name) and I'll resize them for you.
