After your coffee is done brewing, (and the spent k-cup has cooled down), take out the k-cup and pop it down on the pointed top, give it half a twist one way then the other, tap a couple times, and the coffee will fall into the jar while leaving the metal foil on the cup to prevent the grounds that can now go in the compost or garden. Think of the billions of tons of coffee that could help plants grow in the garden! (or lawn with a little rain to help disperse it won't harm the grass)\nAs shown by the gallery pictures, there have been numerous design changes to reach this unusual shape. It would possibly be possible to make it commercially available but this will likely add more plastic waste to our planet and we just know that it can lead to mildew needing to be washed out of the jar every few days or when it fills up, or if you put this shape into a remixed commercial product, it needs a dehydration scheme so the grounds don't sit wet at the bottom.
