Is there an adapter to fill these with a 1lb tank?

Yes, you still use the adapter for 20 lb tanks and add a 20lb to 1lb adapter. This is readily available at your hardware store and it's purpose is to allow you to hook up a 1lb propane bottle to your BBQ for when the 20lb runs out in the middle of a cookout. Sometimes called a "Steak Saver" HTH

Is tank suppose to leak gas after the bleeder valve is closed after filling?

No it should not leak after filling. But the smell of propane is strong give it a minute after filling to air out.

Why is it called a 1/4lb tank? It weighs half a pound empty and only holds about 1.5oz of propane.

It hold 50 grams of propane. I have filled two of these containers multiple times and 50 g is how much propane can be held. I have a YouTube viewer that independently verified the weight. The claimed 3.85 ounces is approximately 100 g which is double the actual capacity. Maybe the flame king company and explain. For fun I filled up one of these tanks with butane, and I weighed the fuel as 65 g.

Im loving how the cylinder looks, but is it a snap head or a screw on head?

it is a screw on head, the same as standard 1lb propane bottles to screw onto propane torches and anything that takes those
