This project aims to develop a drinking bottle that is hygiene-friendly, sustainable, and functional, with a particular focus on active families and children. The goal is to create a drinking bottle that is not only easy to use but also promotes good hygiene and reduces the risk of infection transmission. To achieve this, a stainless steel bottle with double openings and a rotatable construction has been designed, facilitating cleaning and improving hygiene standards. Market research performed shows that the target group prefers metal bottles with simple openings, which offers opportunities for differentiation from plastic-based competitors. In addition, sustainability has been a central part of the development, where the use of environmentally friendly materials has been prioritized to minimize environmental impact and promote a more sustainable lifestyle. Through concept development and CAD modeling, a prototype has been created that combines user-friendliness, hygiene, and sustainability in an innovative way. In summary, the project strives to offer a drinking bottle that not only meets market and target group needs but also contributes to a healthy and environmentally friendly solution for everyday use.
