The Sismo water bottle takes its inspiration from faucets, as the top part of the design could easily be mistaken for a tap.
The bottom half of the design looks very similar to most water bottles, with a clear plastic being used for the material. For shaping, the design moves inwards the closer it goes to the top of the bottle, adding a small but interesting touch to make it stand out on the shelves.
Not only does the tap lid look great, but it also makes the water bottle a lot easier to open. Oftentimes people are stuck attempting to open a tight top, but this ergonomic design solves these problems for many people (just be sure to not close the lid too tight to begin with)!
