is the cap spillproof with center that can be punched out

No it is not the 'spill proof' type, the cap will need to be removed before the bottle is tipped into the dispenser. I bought these simply to prevent spillage after I refilled my bottles at the grocery store. They are not airtight and would not be good for long term water storage.

The top unscrews leaving an opening of about 2 inches to pour liquid out. When the cap is screwed on tightly, the contents will not leak out.

The inner cap has a very small lip from the main collar that the cap screws onto...I found by working the lips apart I was able to use needle nose pliers to pull the inner cap off...and with the dented lid, I could reseal the can. I confess that I almost just punched a hole in the inner lid to pop it off....but didn't

it has a drain plug but the cap is designed to not be unscrewed without destroying the cap, like a child-proof cap.

It fits through perfectly and could be possibly be locked but I am not sure. I do know that once it is in place and the cap is on, it doesn't move. I woud definitely buy this item again but I have two of them and that is all I need at this time. Hope this helps.....

The cut out is for use as a bottle opener. I have not used it to pry a cap off yet, but judging from the design and depth of the tooth it should be highly functional for that purpose.

It is pretty much spill proof. I've knocked mine over with no spills. If held upside down the liquid would come out.

No it has a great closable pour opening that is easy to drink from or put a straw in.

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.

That is the inside of the underside of the lid. The lid has a few layers/components (most of which come apart for cleaning). Easy to put back together. And that hook clips the next layer onto the top and that's what makes it TOTALLY spill-proof! I love mine, by the way :)

There is a pour spout within the cap so it doesn't have to be totally unscrewed.

No, it's not spill proof. There's a little opening in the lid to allow fluid to pour through. And btw, using that opening for pouring drinks tends to be a little sloppy. So it ended up not having much purpose, and I finally through the lid out. Aside from that it serves well for cold drinks in the frig.

Though it looks loke the real lens cap, it does not have a hole or a sliding trap or something to take a sip. It is threadable, no leaking problems for me.It is good for desk & office use, not recommended for traveling since you have to remove the whole cap to drink fro it.

They sell the pint lid (http://www.amazon.com/Klean-Kanteen-Pint-Water-Bottles/dp/B00EAIYQ12/ref=sr_1_4?ie=UTF8&qid;=1422984886&sr;=8-4&keywords;=Klean+Kanteen+lid) which is not spill proof, but will keep drink from slopping out when you move the cup. Not sure if that answers your question.

It is not designed to function like that. It will leak or the cap will fall off if held upside down.

hello, yes there is a fairly thick seal in the inside of the cap. The liquid truly locks in.

I am not confident I understand the question. If you are asking how effective the attached cap prevents leaks and spills. I have not experienced any leaks or spillage as long as the cap is secured tightly. I would recommend purchasing this product because it keeps your cold beverages cold and your hot beverages hot.
