Even better, Fill it with water and freeze it. The water will expand as it freezes and should force it apart.

Try to blow air in through the open cap? (using a vacuum in reverse or a foot pump, with a hose adapted to the cap opening) I think there is a Jobo pump for opening their tanks, when hard to break the seal.
Alternatively, fill it half full of water and shake it, so the water weight pushes on the lid from inside.
I don't think heat or cold is going to have much effect, because the tank and lid are the same material and in good thermal contact.
Go to an auto supply store and look for what they might have in the way of oil filter removers. Get two, one for the can and one for the lid. It might work!
Maybe try Aero-kroil?

Thanks; that idea made sense. The way I did it was I took a slim punch and did some careful taps with a light hammer. That did the job. I'd hesitated to try anything like that b/c I didn't want to damage the tank. This worked out, with no scratches.
Inside, I found some packing material...
I'm surely the person who melted it all but, from the beginning, that was probably what was caught between the cap and the main body of the tank.
A bit of cleanup, and as good as new. All moves freely, the cap fits to the body with the expected amount of friction. No distortion, after all the abuse and no scratches. So I have to say, a tough and very durable product.
I sort of feel like I put this tank through a Top Gear "you can't kill this" episode.
I was kidding about the sledgehammer, but I did think about ether. You know; then throw a match at it...
Thanks to all for the suggestions.
I just received a nice, kind, reply from Mr. Liu. Very helpful, entirely pro:
"I have received your letter.B&W KING problem solved?
B&W KING's lid (B) tank body (C) design is buckle structure, no thread.Because of the need to reduce the dripping water leakage, the processing between (b-c) is more rigorous.
In order to avoid transport impact, the development tank has a plastic bubble packaging to isolate the film mounting frame.
The problem you have, I think, is probably a problem with the plastic packaging inside the development tank, squeezed between (b-c).
As long as the wood block or plastic (non-metal), along the direction of (D) gently tapping, can be solved.
I hope you can solve the problem easily.
I'm a retired large format photographer.Now I am 66 years old. Every product of B&W KING is adjusted, processed and inspected by me to ensure smooth operation and no defects.I was also the first user of B&W KING.
