摘要

A single cup disposable coffee brewing device foldable from a generally flat position to an unfolded position. The device has a coffee filter on the interior and a cardboard main body portion on the exterior and can be placed on top of a cup or mug. Coffee grounds are disposed in the filter and hot or cold water is poured into the unfolded device. The main body portion has a hole at bottom normally closed by a sealing element which dissolves after a predetermined period of time and allows brewed coffee to drip out into the mug or cup.
