Personal hydration system with an improved mouthpiece
First Claim
1. A personal hydration system for use in providing fluid to a user, the hydration system comprising:
- a reservoir configured to hold a supply of fluid and including an output port through which the fluid may be passed;
a flexible hose with first and second ends, the first end being connected to the output port; and
a mouthpiece connected to the second end of the hose and configured to be placed in the user'"'"'s mouth to provide fluid delivery thereto, the mouthpiece comprising;
a neck portion mounted on the second end of the hose; and
a head adapted to be received in a user'"'"'s mouth and including a dispensing face with a perimeter and a minimum dimension between opposed points on the perimeter, wherein the head further includes a bite region extending from the perimeter generally toward the neck to a lip-receiving shoulder, the lip-receiving shoulder extends from the bite region to the neck, and the bite region has a length measured from the perimeter to the lip-receiving shoulder which is less than the minimum dimension.

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 lip-receiving shoulder, which extends from the bite region to the neck, and the bite region has a length measured from the perimeter to the lip-receiving shoulder which is less than the minimum dimension. 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.

13. A personal hydration system, comprising:
-
a reservoir configured to hold a supply of fluid and including an output port through which the fluid may be passed; a flexible hose with first and second ends, the first end being connected to the output port; and a mouthpiece connected to the second end of the hose and configured to be placed in the user'"'"'s mouth to provide fluid delivery thereto, the mouthpiece comprising; a neck adapted to receive a supply of fluid from the hydration system; and a resilient head in fluid communication with the neck and having a dispensing face with a pair of lips defining a normally closed slit extending therebetween to provide a sealable opening through which fluid is selectively dispensed when the lips are urged from a closed position, in which the lips extend against each other to close the slit and prevent fluid from being dispensed therethrough, to a dispensing position in which the lips are spread at least partially away from each other to enable fluid to be dispensed through the slit, wherein the face further includes a plurality of resilient ribs extending from the lips along the face to bias the lips against each other. - View Dependent Claims (14, 15, 16, 17, 18)

19. A hydration system for use in providing fluid to a user, the hydration system comprising:
-
a reservoir configured to hold a supply of fluid and including an output port through which the fluid may be passed; a flexible hose with first and second ends, the first end being connected to the output port; and a mouthpiece connected to the second end of the hose and configured to be placed in the user'"'"'s mouth to provide fluid delivery thereto, the mouthpiece comprising; a neck adapted to receive a supply of fluid from the hydration system; and a resilient head in fluid communication with the neck and having a dispensing face with a pair of lips defining a normally closed slit extending therebetween to provide a sealable opening through which fluid is selectively dispensed when the lips are urged from a closed position, in which the lips extend against each other to close the slit and prevent fluid from being dispensed therethrough, to a dispensing position in which the lips are spread at least partially away from each other to enable fluid to be dispensed through the slit, wherein in the dispensing position the slit forms an opening with an area sufficient to dispense fluid from the mouthpiece at a flowrate greater than 30 ml/sec when the mouthpiece is placed in a user'"'"'s mouth, urged to the dispensing position and drawn upon by the user. - View Dependent Claims (20, 21, 22, 23)
