are the threads covered by the cap? in other words, does the cap fit down OVER the threads, or does the cap thread down INSIDE the bottle's threads?

Yes..The threads are formed at the top and the cap covers the threads..when you drink 'straight" from the bottle your mouth is on the threads..I hope that answered your question?

Here are two views of the threads under the brass cap. http://i122.photobucket.com/albums/o270/azpyroguy/Posts/20131110_135718_N134thAve_zpsc22420c2.jpg http://i122.photobucket.com/albums/o270/azpyroguy/Posts/20131110_135747_WLisbonLn_zpsad94a6bd.jpg

This one is threaded. Luckily the threaded bottles have all been the smaller diameter. The crown style that comes with water delivery service and the no-spill caps that pop over the dispenser are the larger size. I have both and these spouts are so easy to work with in my home - much easier than a standup dispenser when room temperature water is perfect.

The threads dont' leak. When the lid is closed, it is fairly secure. HOWEVER - when you take a drink of coffee from the lid, the coffee doesn't flow back into the bottle, it collects around the flip part and gets forced out when you close the flip. Then it ends up all over the bottle and your hands. I hate it.

Two solutions. If cap is screw on measure the size of probe in center of where the bottle sets. Drill cap to 1/8 inch oversize and use clear plastic screw lid with plastic over bottle. Probe will puncture it and dispense water. Blue snap on lid, do same. Non removable cover with plastic push-out center. Cover with clear wrap and heavy rubber band around neck. Probe will puncture. I use all three and have for several years and it works well.

I haven't had any trouble with mine, just have to make sure it is secure to your cap....

It does not screw on but rather pops over the opening of the bottle and then you tighten it and it works just fine. I've been really happy with mine. I think it should work for you.

I purchased this bottle and I have not had any problems with the cap accidentally opening. I carry the bottle in my bag with my books, cell phone, tablet, etc. The cap is secure and stays tight withstanding movement very well.

The first time I used it the cap screwed in about half way. But, there was only a few drips and i did not want to dammage the threads by over tighting. Now after severell drains and fill ups it screws down better.

I've bought two of these. The first one, I was not able to. The second one didn't really have that problem.My experiences from the first one was that no matter how tightly I screwed the cap on, it would still leak if the bottle was on its side. I never had an issue from either of mine leaking from the cap when it was right-side up. If it leaks from that position, you probably should get a new one because that's not supposed to happen whatsoever.

Yes, there is plastic that would be in contact with the liquid. The cap screws on and is plastic, both on the outside and inside.

As far as I can tell, only the provided bottles work. However, you might find another bottle with the same type of threads.

I believe they would. There is a washer in the cap and the bottle has 2 grooves of threading so it screws down pretty well.

Yes, it is "machine threads" and very tight. The end cap has a ribbed surface. Try harder!

The previous answer is correct: the cap assembly is lined with some type of plastic. Since the metal part of the bottle screws inside of the plastic, most of the plastic in the lid is covered unless some liquid gets down into the threads somehow. I would guess the area of plastic exposure is a square inch or a so. The label states the bottle is BPA free.

I honestly don't know. I leave the cap loose on mine and that has prevented any pressure build up.

The lids I have do have a very thin foam / plastic that covers the entire inside of the cap ( but not the threads).
