The TFusion was created after much frustration with tea bags which create a mess when you pull them out to keep tea from getting bitter. The bags would also block the lid opening or float in the way of my lips when drinking straight from the cup. My design keeps the tea at the bottom via a paper diaphragm that is swaged into a cup. Functional cut patterns and screening allow tea to be infused by simply tapping on it. Tfusion allows for control over strength, speed of infusion, and keeps the bitterness contained at the bottom of the cup.
