This report describes a Bachelor thesis executed at Jönköping University in Mechanical engineering, specialized in product development and design by Adam Gustafsson and Thomas Persson. The thesis was made during the spring of 2018 and was the final assignment before graduation. Unadvised aluminum cans that are unsealed run risk for bees and wasps to intrude the can. This may have devastating consequences, not least for people with allergy to stings of bees and wasps. Therefore, a need was determined of a product that prevents stings to mouth and pharynx when it comes to drinking from a can. An assignment from Axelent Engineering became the groundwork of this report. The goal of was to generate suggestions of concepts with a safety lid that would eliminate risks from unsealed cans, minimize spill and preserve the characteristics of the drink. From perspective of the client demands and the issues described in the report a result could be presented. Highest priority was the development of the product but desirable was also to implement research of the market, material selection and sales preparations. Based on the theories and methods presented in the thesis two suggested concepts could be screened, which later was weighted to become one final concept. All concepts were compared with starting point from the requirements which revealed the final concept. The result was a compact safety lid that was the best alternative and met the requirements for manufacturing, function clarity and selected target group. The thesis contributed to increased knowledge in the field and gave a clear picture of how the product development process could be. The assignment resulted in a functional prototype that lays the foundation to continue develop into a finished product. The final product aim to increase the comfort and awareness among the consumer.
