Auto Generating Coffee Cup Cooling Collar

on March 26, 2010 12:15 pm

Those of you that frequent Starbucks and other coffee shops are quite familiar with the thin cardboard collars that can be slid over your cup to keep your hand from melting. The guys at have come up with a much niftier alternative. It’s the Heatswell coffee cup. I has the insulating collar built right into it. As soon as you pour the hot beverage into the cup, it will start to swell, creating a terry cloth like band around the cup. The material is non-toxic, FDA approved, recyclable and biodegradable.

    So…why can’t they just put a layer of terry cloth-like material on there that’s…just there all along. Why must it inflate?

    @Blake Think about it… if there was a thick layer around the cup, it wouldn’t stack / ship well… :)

    I wonder if it returns to status quo ante once the liquid cools or is removed. If so, we could add “reusable” to the list.

    @AndyM I asked that question and unfortunately, it doesn’t return to the unexpanded state when it cools.

    I wonder when they are going to start selling these for a dollar next to the check out similar to the reusable grocery bags phenomenon that has hit.
