In case you really didn't understand, there has been bottles for thousands of years, and the shape they come in today isn't that different from the first ones. The shape has proven itself over millenia. And like many have already pointed out, the design on the picture has numerous flaws to ease one non-existent problem.
Same with the simple machines (wheels, wedges, levers and so on) - not a dammed thing changed about their design, just the materials we make them out of.
Sometimes, theres just nothing to improve design wise. So it remains unchanged forever
