Is there a term for when you buy a consumable product, but you can't use a certain percentage of the product due to the company's packaging?

I bought a squeeze-bottle of mayo since the method of use was easier (just squeeze and done, rather than use a spoon or knife), and the price was the same for the same amount in a jar or squeeze bottle, so it's not that I'm getting more or less for different packaging.

However, I've come to realize that when you get near the end of the squeeze bottle, you can't do anything to get that last 10% out due to the narrow neck, where I definitely could use a spatula in a jar.

"Wastage" came to mind, but I feel that is more along the lines of "it spoiled" rather than "I can't access it", but technically, that's still waste.

I'm just wondering if there's a way to define "wastage through design" or something like that
