ABSTRACT:
A hydration system is disclosed for carrying readily dispensable fluids, such as water. A removable cap having an annular valve covers a container. A flexible tube is disposed through the center of the annular valve and extends generally to near the bottom of the container. A bite valve is attached to the end of the tube that is external to the container. When the annular valve is closed, the hydration system is substantially closed, preventing fluid loss. When the annular valve is opened, an air channel is created that allows air to enter the container, facilitating the flow of fluid from the container through the flexible tube. The annular valve may be a poppet-type valve having a valve stem that is movable between the closed position and the open position. The hydration system is sufficiently compact to be utilized with narrow-mouthed bottles.
