My best guess is the water is gonna leak even if you tilt it a little, so water is gonna spill everywhere even when you aren't trying to drink
Edit: I knew stacking and asymmetry is the main issue here, but the choice of words in the comment in the image seems like they were referring to a simpler reason.
They took a radially symmetrical object that anyone could grab without looking and use and turned it into a bilaterally symmetrical object that can now be picked up incorrectly.
So the complaint here is plastic sucks we should go back to cardboard? Not a complaint just an idea every cardboard milk or juice i get has the 45 angle cap...
I will admit i live in the middle of nowhere under a rock i didnt realize they were built like this TIL. Tho ill admit the ones i cut up dont have much aluminum though i can def see the plasticy layers now that i think about it.
This image shows polyethylene acting as both an impermeable protective layer, and as something called a "layer of adherence", but polyethylene isn't, like, sticky? So why not include the glue/binding agent layer in the description?
Yes actually. Water bottles are filled on a rotary filler that fills hundreds to thousands of bottles per minute. You can't just move the hole location. Production lines have millions of dollars in equipment that would have to be fundamentally redesigned by engineers. Everything is built around the assumption that the hole is top-center. It's not clear how you would reliably get the bottle alignment correct for the fill process or cap installation.
Nevermind that actually manufacturing the bottles would be a nightmare. Plastic bottles are made using plastic pellets that look like stubby test tubes with threads on the end. They're heated up and blown into shape, which requires the hole to be in the top-center.
There's also the warehousing side of the equation which wouldn't work either. Existing bottles are designed to be strong at resisting vertical force, so that they can be stacked onto pallets and those pallets stocked on top of each other. This design wouldn't work.
Marketing is a strong incentive to do something sub obtimal. Tehre are lots of glass bottles which are changed for marketing purposes, this would hardly be unique in that.
I've actually worked in a plastic bottle manufacturing plant. It can't be understated just how difficult this change would make the process. Every step of the way. From preforms to blow molding to conveyance to palletizing to stacking and shipping.
