Abstract
A personal hydration system with an improved mouthpiece for use in providing fluid for delivery to a user. The mouthpiece includes a neck that is adapted to be mounted on a supply tube to a hydration system and which is joined to a resilient head. The head includes a dispensing face with a pair of lips that define a normally closed slit, through which fluid is dispensed from the mouthpiece, a perimeter and a minimum dimension between opposed points on the perimeter. The bite region extends from the perimeter to a shoulder, which joins the bite region and the neck. From a closed position, in which the lips extend against each other to close the slit and prevent fluid from being dispensed through the slit, the mouthpiece is deformable to a dispensing position in which the lips are spread at least partially away from each other to allow fluid to be dispensed through the lips.
