These portable water bags use efficient design to be a smarter substitute to water bottles. Water dispensers have several deficiencies and this company offers an alternative for safer and more convenient solutions to drink water.
The 'Vacuum Water Bag' was designed by Dalian Nationalities University's School of Design as an alternative to conventional water dispensers. Water dispensers can be bulky and difficult to carry -- but this portable water bag can be transported with ease thanks to an integrated handle.
The conventional water dispenser also carries more bacteria because the air inside the container mixes with the water that people drink. The Vacuum Water Bag flattens during use to eliminate air from the container -- preventing contamination for a safer, more portable water bag.
