>A burger is defined by its assembly and presentation, inside a burger bun and stacked vertically.
This is probably the most widely understood definition outside of North America.

>bread that contain a burger patty are burgers
That would be the Louis Lunch argument, since they claim to be the original burger restaurant, and they use thick toast, not buns.
However throughout the US a burger patty with toast is usually called a patty melt, not a burger.
Despite having the same ingredients and assembly and taste as a burger, it isn't using burger buns, so it's a melt.
The most important thing to understand is that outside of North America, ground beef is never referred to as burger.
It is known as ground or minced beef. Never burger.
It's only a burger when it's cooked and assembled inside burger buns.
If it's between sandwich bread slices, it's a sandwich. Just like a patty melt is a sandwich.
