Rethinking a coffee package

Work in progress
 
The Brief:
Create a sustainable or reusable “powder” goods package (e.g. coffee, cocoa, tea).

The Solution:
A completely reusable coffee package that transforms into a pour-over coffee system after the grounds have been used.
 
The package is composed of 4 separate parts. At the base is a coffee mug. Above the mug is a ring that has a hole cut in the center. Above that is a funnel that will function as a pour-over coffee funnel. Finally the cap will be the size of a tablespoon to measure the amount of coffee to be used with a cup of water.
When the coffee grounds have been consumed, the package can be taken apart and used to make pour over coffee. The funnel flips over and is inserted into the hole in the center of the ring, and the ring sits easily on the top of the mug.
