About Reusable Foldable Cup
Reusable is a foldable cup designed for drinks consumed away from home. The cup collapses into a compact form that fits in a pocket or a bag. Reusable is made from food-grade silicone and BPA-free plastic, shaped by injection molding. The cup holds 250 ml and measures 87 mm in width and 122 mm in height. To open the cup, the top rim is pulled up until it locks in place. To close the cup, the rim is pushed down until it folds flat. Reusable offers an alternative to disposable cups and helps reduce waste.

- Production Technology
- The foldable cup design was achieved through iterative prototyping using CAD software. We employed injection molding for precision in mass production, utilizing food-grade silicone and BPA-free plastic to ensure safety and durability.
- Design Challenge
- The toughest challenge in this design activity was achieving a balance between compactness and durability. Creatively, we faced the obstacle of ensuring the cup could fold efficiently without compromising its structural integrity. The final concept of the foldable cup emerged as a response to countless iterations, material testing, paper prototyping, and 3D printing.
- Research
- The final concept of the foldable cup emerged as a response to countless iterations. In the process, a huge role played sculpting through various types of prototyping. Paper prototypes were used for proportion and geometry relationships, and 3D printing prototyping with soft plastics was used to test shape and thicknesses. Followed by extensive research on materials from which to manufacture.
- Inspiration
- Reusable's journey began with a simple question: How can we make eco-friendly choices effortlessly integrated into our routine? Inspired by the beauty of simplicity and functionality followed by the quest to create a solution that combines convenience with sustainability. Reusable boasts a unique collapsible design that transforms it from a full-sized cup into a compact, pocket-friendly form factor.
- Project Duration
- The idea was born in 2019, but the project commenced in January 2023 and concluded in April 2024. The design and development phases took place in Bulgaria. This timeline allowed for extensive research, prototyping, and user testing, ensuring the final product met high standards of functionality and sustainability.
- Operation Flow
- The foldable cup is easy to use. To operate, simply expand the cup by pulling on the top rim until it locks into place. To collapse, push down gently until it folds flat.
