Sport water bottle with high flow rate
A bottle assembly has a bottle and a removable cap. The cap includes a nozzle and a vent arrangement. The vent arrangement can include a vent conduit that extends into an air cavity present at the bottom of the bottle assembly when the bottle assembly is inverted. The vent arrangement allows for pressure equalization within the bottom assembly in response to liquid being dispensed from the bottle assembly to permit high flow rates of the dispensed liquid without squeezing of the bottle.
1. A sports beverage bottle assembly, comprising:
a bottle defining a closed bottom end and an open top end;
a cap selectively connectable to the bottle and configured to close the open top end of the bottle, wherein the bottle and the cap cooperate to define an interior space, wherein the cap defines a cavity located above the open top end of the bottle with the cap attached to the bottle, wherein a volume of the cavity is at least about 5% of a volume of the interior space;
a nozzle carried by the cap, the nozzle movable between an open position and a closed position, wherein liquid contents of the bottle can be dispensed through an outlet passage of the nozzle when the nozzle is in the open position, wherein an outlet opening of the outlet passage extends through an upper end surface of the nozzle;
a vent configured to permit a vent flow of vent air from an atmosphere outside of the bottle assembly to the interior space of the bottle assembly through an elongate vent passage that extends through the cap;
a vent plug comprising an elongate projection configured to be received within a cylindrical portion of the elongate vent passage to selectively open and close the elongate vent passage;
a dividing wall within the elongate vent passage and between the cylindrical portion and the interior space of the bottle, the dividing wall comprising a plurality of vent openings extending therethrough;
a check valve that selectively covers the plurality of vent openings and is configured to permit the vent flow of vent air and inhibit or prevent a flow of air or the liquid contents through the elongate vent passage in a direction from the interior space of the bottle assembly to the atmosphere;
a vent conduit that extends from the vent passage to a terminal end located within a bottom 10% of the bottle when the cap is connected to the bottle;
wherein the bottle assembly is configured to dispense the liquid contents through the outlet passage of the nozzle in response to the bottle assembly being tilted sufficiently toward an inverted position for the liquid contents to enter the outlet passage of the nozzle.
2. The sports beverage bottle assembly of claim 1 , wherein the movement of the nozzle between the open position and the closed position is linear movement.
3. The sports beverage bottle assembly of claim 2 , wherein the cap comprises a tubular nozzle receiver that supports the nozzle for movement between the open position and the closed position, wherein the tubular nozzle receiver and the nozzle cooperate to define one or more windows that permit entry of the liquid contents into the outlet passage of the nozzle.
4. The sports beverage bottle assembly of claim 3 , wherein the one or more windows define a total area of at least 65 square millimeters.
5. The sports beverage bottle assembly of claim 4 , wherein the outlet passage of the nozzle defines a minimum diameter of at least 9 millimeters.
6. The sports beverage bottle assembly of claim 1 , wherein the terminal end of the vent conduit is located adjacent the closed bottom end of the bottle.
7. The sports beverage bottle assembly of claim 1 , wherein the vent conduit is removably connected to the cap.
8. The sports beverage bottle assembly of claim 1 , further comprising a water trap positioned between the vent passage and the terminal end, the water trap configured to accommodate water from within an interior of the vent conduit.
9. The sports beverage bottle assembly of claim 1 , wherein the vent plug moves with the nozzle.
10. The sports beverage bottle assembly of claim 9 , wherein the vent plug and the nozzle are formed as a single piece.
11. The sports beverage bottle assembly of claim 1 , wherein the cap is connectable to the bottle by a threaded connection in which threads are located on an interior surface of the bottle.
12. The sports beverage bottle assembly of claim 1 , wherein a ratio between a minimum cross-sectional area of the outlet passage and a minimum cross-sectional area of the vent passage is equal to or less than about 14:1.
13. The sports beverage bottle assembly of claim 1 , wherein the cap comprises a tubular nozzle receiver that supports the nozzle, the tubular nozzle receiver comprising an elevated inner platform with a lateral sealing surface and a vertical sealing surface, the nozzle comprises a round sealing surface, wherein the round sealing surface abuts the lateral sealing surface and the vertical sealing surface.
14. The sports beverage bottle assembly of claim 1 , wherein the bottle comprises an outer layer of a grip material.
15. The sports beverage bottle assembly of claim 1 , wherein the bottle is constructed of a rigid metal material such that the bottle is non-squeezable.
16. The sports beverage bottle assembly of claim 1 , wherein an outer surface of a sidewall of the bottle defines a shoulder that extends in a circumferential direction around the bottle.
17. The sports beverage bottle assembly of claim 1 , wherein the nozzle is removable from the cap.
18. The sports beverage bottle assembly of claim 17 , wherein the nozzle comprises an indicator to indicate to the user the location on the nozzle to push for removal of the nozzle.
19. The sports beverage bottle assembly of claim 1 , wherein the bottle assembly is adapted to dispense 21 ounces of liquid from the bottle assembly in 10 seconds or less using gravity force alone.
