This water cooler bag idea would replace the usual plastic bottles that you refill to your drink stand. The regular canisters are great with the generous quantities of liquid that they hold, but there are a slew of disadvantages to using them.
Consider this Vacuum Water Bag, by a team of designers from the Dalian Nationalities University. It proposes smaller reservoirs of H2O that are easier to handle, and even possible to carry in multiples. Broad handgrips make the entire process from purchase to installation quite convenient, not requiring the same muscle and technique typically needed.
But beyond ergonomics, the water cooler bag concept comes with a suggestion of being more sanitary. The creatives explain that the pressurized sack will contract with its contents, reducing possible airborne germs by up to 90 percent.
