I like the classic solution of a bar that appears when you go with the mouse to the screen's top (or bottom). Like Nelly Cootalot, for example (see screenshot at the bottom).
Depending on the style of your game, you might want to use a frame or just a transparent bar with some opacity or just black (like Machinarium).
I do not like inventory screens that open on top of the game screen.
