A liquid dispensing container has an outer shell including a wall having an inner surface and an outer surface. An inner core is coupled to the outer shell and has an outer surface and an inner surface that defines a reservoir configured to contain a fluid. The inner core and outer shell cooperatively define a longitudinal axis. A liner is positioned between the outer shell and the inner core. The liner comprises a stretchable material that is in stretched along the longitudinal axis.

A hydration bladder according to an embodiment of the present disclosure includes a flexible body having a first stiffness. A port is coupled to the flexible body. A liquid chamber is formed by the flexible body. The liquid chamber is configured to carry a liquid therein and in is communication with the port. A reinforcement member is coupled to the flexible body. The reinforcement member having a second stiffness, and the second stiffness is greater than the first stiffness. The reinforcement member includes a first width, a second width greater than the first width, and a third width disposed on an opposite of the second width than the first width. The third width is less than the second width.

It is common for the organizers of endurance sports to provide aid stations along the route where participants may receive water to prevent dehydration. To reduce waste at these events, organizers encourage ‘cupless’ races that requiring participants to carry their own vessels. The present invention comprises a hat with a visor, such as a baseball style cap, with a collapsible drinking vessel integrated into the visor. During the course of the race, a runner may encounter a water stop and require a vessel to contain the liquid for immediate consumption. At such time the runner can simply remove their hat and configure the vessel to the open position to receive the liquid. Post-consumption the vessel is configured back to the closed position and becomes seamlessly integrated into the visor with no negative effects upon the runner.

Bite-actuated mouthpieces and drink vessels including bite-actuated mouthpieces are disclosed. Bite-actuated mouthpieces comprise a body comprising a dispensing wall, one or more sidewalls extending from the dispensing wall that with the dispensing wall define an internal volume, and an inlet to the internal volume. The self-sealing exit is biased toward a closed configuration and is configured to be selectively reconfigured from the closed configuration to an open configuration responsive to user-applied compressive forces to opposing bite regions. The dispensing wall has a dispensing face opposite the internal volume, and in some examples, the dispensing face is concave.
