Most large plastic storage containers like those produced by sterilite have sloped sides so that the top is wider than the base. This of course means that when placed side by side there is a large gap between them of wasted space. Is there a reason for this? Easier to manufacture? Structural integrity?
Edit: Thank you very much to all of you for your responses!

I’ve seen others mention it but the #1 reason for the lips on the container is for nesting. Warehouses want effect Storage space and like products that nest inside without creating a vacuum.
From an injection molding aspect I would argue it makes the mold much more complex due to needing lifters, sliders or other non standard injection mold components. It does add surfaces for injector pins though.
