Device for Improved Hydration During Exercise

Case ID:

This technology encompasses the design for a device that can easily deliver water or other sources of hydration from a bottle, directly to a user during exercise without the use of a traditional hydration bladder.

Those engaging in active exercise such as bike riding, hiking, or rock climbing often desire a way in which they can hydrate from a water or other drink source while still exercising. The common solution for many is a bladder-style hydration pack, with a water reservoir (usually contained in a backpack) with a tube for access while exercising. Camelbak and other outdoor brands primarily all have devices that follow this design, but there are many inherent issues with this model, as the “bladder” or water reservoir can be messy to fill, and can accumulate bacteria and dirt easily, all while being difficult to properly wash and maintain.

In this technology, the inventor proposes a new and improved system with the same purpose: to deliver quick hydration via a tube to an athlete without the exercise having to cease or a bottle having to be opened. The system fits over most existing bottles and would eliminate the need for the bladder portion. This would significantly reduce the risk of microbiological contamination and would allow the user to clean the device much easier.
