This project involves the use of mechanical engineering expertise to develop, design, and create a functioning prototype of a collapsible coffee cup. The prototype is to be designed to the specifications given by Jason Blum, the project sponsor. Allowances may be given for design freedom as specified by Jason Blum. The goal of this project is to create a product which may replace the both the disposable coffee cups distributed at coffee shops as well as to create a product which may replace the traditional travel mug due to its increased portability.

Team Poly Cup has worked throughout the year to design and test numerous locking mechanisms, water-tight seals, grips, and lids and have performed many calculations and created many prototypes to ensure the best design. We have expanded and finalized the design, completed a detailed cost analysis, finalized design verification, developed a manufacturing plan, and compiled a list of unique features that can be patented. In this report, we conclude the project, leaving Jason Blum with a completed prototype of the cup, as well as all documents needed for him to proceed with patenting and manufacturing of the cup.
