About Reusable Katilu Tolesgarria

Reusable etxetik kanpo edanak kontsumitzeko diseinatutako katilu tolesgarria da. Katiluak forma trinko batean tolesten da, poltsiko edo poltsa batean sartzeko modukoa. Reusable elikagaietarako silikonaz eta BPArik gabeko plastikoz egina dago, injekzio bidezko moldaketaz emandako forma duena. Katiluak 250 ml ditu, eta 87 mm-ko zabalera eta 122 mm-ko altuera ditu. Katilua irekitzeko, goiko ertza gora tira egin behar da, tokian blokeatu arte. Katilua ixteko, ertza behera bultzatu behar da, laua tolestu arte. Reusable-k erabili eta botatzeko katiluen ordezko aukera eskaintzen du, eta hondakinak murrizten laguntzen du.

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.
