Ok, so I understand the need to seal many consumer products. I’m talking about those seals that come on the tops of containers that usually contain some liquid, like ketchup or syrup. They have little lift-up “tabs” made of paper or plastic.
The “tabs” start out flat (of course, you don’t find out about the extra seal until you’ve determined that the liquid is not coming out, so you remove the cap), you lift the little “tab”, then you try to pull the seal off. You try.
For me, most of the time, the tab comes off. The seal itself remains wonderfully glued to the container, and my burger is getting cold. Once that tab is freed from its prison, the remainder of the thing is almost impossible to remove. This is pretty much the same, usability-wise, as those old-fashioned seals that you had to remove with some more primitive means, like by stabbing with a knife or punching with a stick (try a windshield washer fluid bottle, if you need a refresher).
Why the heck are they there? Convenience? Nah. Food safety? Ok, I like that one, but they’re still not very friendly. ‘Cause we can’t build a leakproof bottle, and we don’t wanna be sued if the stuff leaks out on the way home? Nah (my trunk smelled like bleach for a year once). But, really, why does a bottle of bleach or soap need these things? Is someone going to tamper with the bleach so I don’t drink it? Pour soda into the soap bottle so everything comes out sticky?
I get more bleach on my hands and clothes trying to get these darn things off…
