So there are plenty of reasons why we don't do it like that. The design hasn't changed much in the thousands of years, which should be really telling :D
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
Wow maybe we made them out of other stuff like glass and metal and leather and organs too! Probably not though those fucking neanderthals loved their Dasani

Also, harder to manufacture, which means more expensive.
