Bottle-Bib - Mold Making and Product Formation
The Bottle-bib was designed for ease of use, simplicity, and portability. The carabiner loop allows you to take it on the road and always have it handy.
The idea of making a bottle top that would serve as a makeshift cap seemed pretty forward, but designing it to be made from a mold proved to be exciting and challenging. After brainstorming a few initial ideas, this one seemed to be the most useful at the time. At first the idea was conceptualized to be made from a square mold. However, I quickly realized this would use a lot of material. Instead it was redesigned on Solidworks to be in the shape of the actual part with a quarter of an inch thickness all around. A flat feature was added in order to provide an appropriate surface to clamp on. The initial design contained very small channels for the off-gassing of the silicone rubber, but these details were omitted from the final mold. A opening at the top serves as the entrance for the silicone rubber mix, however a hole was bored out from the bottom instead in order to provide a smother, uninterrupted flow of the silicone rubber as it was poured.
The final product is a part that seals glass bottles extremely well through deformation to the contours of the bottle.
