This protein shaker is designed to contain a single single-dose protein powder capsule. The shaker can be used as a water bottle and just by pressing the capsule, it breaks and pours the content into the container, allowing you to enjoy protein shakes of the chosen flavor.
The challenge of this project lies in the difficulty of breaking the capsule only when the user wishes, so many tests had to be done to achieve the optimal result.
The necessary tightness complicates the engineering of the parts considerably.
At the sustainability level, the capsule has been made with biodegradable PH4 material at home without the need to take it to a composting plant.
