What Pac said. Top off the rad neck to the brim of the inside lip where the cap seats. You're wanting to get all the air out of there. No magic just pick the type/shape/color of bottle that suits you/looks good. I have a 2 liter plastic pepsi bottle on a DD w a hose to the bottom, a lever stant recovery cap, works fine. When an inventor patented it (then sold it to the car companies) it's selling point was that the elim of air pockets gave more uniform cooling and lowered temps as much as 10 deg (F) and less oxygen from losing the pockets slowed rust development

So I want a bottle with a vent on the top and a "recovery' type cap. The bottle I was looking at (the one that might fit) is 20oz capacity. I worry that a full to the brim radiator will discharge more than 20 oz and spit coolant out the vent. Valid concern?
Also not sure about my cap. I ran the car with a Stant lever cap (model 331) and when I shut it down a bunch of coolant puked out but the upper radiator hose was not hard (no pressure) Maybe it had relieved the pressure before I squeezed the hose? Not sure.
20oz capacity is plenty. Only a high-schooler pukes more than that.
Caps vary in pressure...around 7 pounds is light, around 15 pounds is 'heavy'. Higher pressure raises the boiling point, but it also stress-tests the radiator more.
Again---you want the cap with the button, you can get the lever too.
MOST caps nowadays ARE coolant recovery, with the button.
On my 70'cuda I am using the windshield washer bottle as the coolant tank--works perfect.

The key to recovery is the cap, recovery systems use a cap with a "dangling disc" center valve while the standard system has a valve that is spring-loaded. Also, the cap gasket must seal tight against the neck or there won't be enough vacuum to recover the fluid.
