Vacuum Flask
Development &
Prototyping

In the hard outcome space, the exploration led to the development of a vacuum flask designed for wearability through a specialised carrier. Initial testing began by retrofitting a conventional thermos. As the design evolved, inspiration was drawn from popular drink bottle styles. While both a bayonet fitting and a screw fitting were explored, the screw fitting was ultimately chosen for its ease of use, reliability, and reduced risk of accidental release, ensuring both the efficiency and safety of the device.
