could i sue for drinking plastic in my bottle

You have all the elements for a lawsuit, but in reality you would not likely get much, if anything from it.  In order to sue for a personal injury you have to show: 1. NEGLIGENCE - which you have because obviously pieces of plastic do not belong in your drinking water. 2. INJURY - that you were injured as a result of their negligence.  This is where your case falls short because although you were injured, your injuries were pretty minor.  Attorneys who take on these kinds of cases are generally looking for catastrophic injuries, like if you had actually choked and died or suffered brain damage - that would be a great case!  That's because you can collect for your medical bills, for lost wages, and for pain and suffering.  You have no medical bills or lost wages and your pain and suffering would probably be determined by a judge or jury not to be worth that much.  An attorney would never take this case because it requires an enormous amount of work to bring this type of case, so we only do it where the potential pay-off is great. 3. CAUSATION - You have to show that your injuries were caused by their negligence.  That is pretty clear in your case so that is not a problem. 4.  DEEP POCKETS - Another thing we look for in evaluating cases is whether the defendant has the ability to pay any judgment we obtain or whether they have insurance coverage.  This should not an issue in your case because you are dealing with a well-established company. So to summarize, you have all of the elements of a lawsuit, but your case is not worth enough to be worth an attorney's time to take it on.
