ELI5: Why do companies design bottles in such way that you can't get all of the product (e.g. Ketchup or shampoo) out of the bottle?

function is one of the lesser priorities when designing a product that is going to be seen on store shelves especially. The aesthetic is going to drive more sales than the amount of product that gets stuck in the bottom of the bottle. Also there is a shipping aspect, fitting as many of the product into as small of a box as possible, which means designing the bottles in a way that lets you stack them efficiently.
