Abstract
A hydration system includes a liquid reservoir, a bottleneck plug, a tube, a hydration valve (e.g., bite valve), and a flow-restricting device (e.g., check valve). The tube comprises a first end for coupling to the liquid reservoir via the plug, a second end having the hydration valve, and the flow-restricting device interposed between the liquid reservoir and the hydration valve. The plug may be inserted into a variety of bottlenecks.
Claims3
A hydration system comprising:
- a collapsible bottle;
- a tube comprising
- a first end and a second end, the first end comprising a cylindrical plug and the second end comprising a bite valve,
- the cylindrical plug comprising pliable materials so as to be receivable within a neck of the collapsible bottle via interference fit, the cylindrical plug thereby sealing the collapsible bottle;
- the cylindrical plug further comprising a channel therethrough to allow liquid to pass through the channel when under suction;
- a check valve interposed between the bite valve and the collapsible bottle to prevent backflow into the collapsible bottle;
- wherein the bite valve and check valve are:
- i. absent actuation by a user, both in a closed position, and
- ii. independently actuatable by:
- a. a user biting the bite valve to thereby open the bite valve, and
- b. applying suction to the tube to thereby actuate and open the check valve;
- wherein when a user bites to open the bite valve and suction is applied to the tube, the check valve allows liquid to pass from the collapsible bottle to the user;
- and
- as liquid passes from the collapsible bottle, a volume of the collapsible bottle decreases from a first volume to a second volume, the second volume less than the first;
- and
- wherein when suction is stopped, the check valve closes due to vacuum pressure in the collapsible bottle which thereby prevents water from passing back through the tube into the collapsible bottle, the bite valve actuatable to prevent backflow from the user's mouth to the tube.

- the cylindrical plug comprising a channel therethrough to allow liquid to pass from the collapsible bottle to the tube when under suction;
- a check valve interposed between the bite valve and the collapsible bottle to prevent backflow of liquid into the collapsible bottle;
- wherein absent actuation by a user, the bite valve and check valve are both in a closed position;
- and
- wherein the bite valve is configured to open when actuated by a user and wherein the check valve is configured to open when suction is applied by the user;
- wherein when the user bites to open the bite valve and suction is applied to the tube, the check valve opens to allow liquid to pass from the collapsible bottle to the user;
- and
- as liquid passes from the collapsible bottle, a volume of the collapsible bottle decreases from a first volume to a second volume, the second volume less than the first;
- and
- when suction ceases, the check valve closes due to vacuum pressure in the collapsible bottle which thereby prevents water from passing back through the tube into the collapsible bottle, the bite valve actuatable to prevent backflow from the user's mouth to the tube.
