Too Weak to Open Caps. Need a U-Cap

Plastic caps were designed to keep liquids in. Then at the last minute somebody realized people actually have to remove them to get to the liquid so they threw on some groves around the cap for grip and called it a day. Bah I say! I will admit sometimes I can’t do it! That cap just won’t let go. Maybe I need a U-Cap.

There’s a soft asymmetric curve on one side of the cap, perfect for thumb grips. This single design element transfers more torque as you turn requiring less effort. Designed primarily with the elderly, children, and disabled peoples in mind, the U-Cap would market well for people like me; I guess you could call them lazy. I kid, I kid.

On a serious note, the U-Cap is Earth friendly too. Made entirely of biodegradable polyolefins and starch, it dissolves with long term exposure to water and microbaterial decomposition. Yay for planet Earth and less sore thumbs!

    This is genius! Great work!

    it dissolves in long term exposure to water…..

    it dissolves in water

    Please don’t say this cap is for water biased products.

      If you read the article you would understand they’re talking about decomposition, not just exposure to the soda or whatever liquid it’s capping in.

    Ah, this is a great idea. OP, please follow-up on this and keep us posted. I know it’s a little old but if this ever gets made, I’d buy a few.

    Great idea! – now I wonder why nobody thought of such a “simple” thing before.

      they have, at the dollar store, in silion rubber though (non bio degradeable)

  • yup says:

    Packaging cost already outweighs the cost of the product inside. Something like this, however desired by some consumers who have trouble opening caps, is still unfeasible to manufacturers.

    • iSH says:

      I have to agree with yup the manufacturing costs would increase BUT its an interesting concept none the less. Probably for the more ‘richer’ water bottles. If you want more out of a bottle your going to have to pay for it one way or another.
