Disclosed are embodiments of a squeezable drink bottle and a cap assembly therefor. The cap assembly can comprise a rigid cap body configured to be secured to a liquid container, a spout comprising a resiliently flexible tube extending through a passageway in the cap body, and a shut-off trigger slidably mounted in the cap body and adjustable between an open position and a closed position relative to the cap body, wherein when the trigger is in the open position, the tube is open to allow liquid to flow through the spout, and when the trigger is in the closed position, the tube is closed to block liquid flow through the spout. The cap assembly can also include a mouthpiece valve that remains sealed until the bottle is squeezed to pressurize a lumen within the mouthpiece and squirt fluid out of the spout or the mouthpiece is pinched to open the seal.

1. A cap assembly for a liquid container, comprising: a rigid cap body configured to be secured to a liquid container;a spout comprising a resiliently flexible tube extending through a passageway in the cap body, the tube comprising an inner lumen for conducting liquid; anda shut-off trigger slidably mounted in the cap body and adjustable between an open position and a closed position relative to the cap body, wherein when the trigger is in the open position, the lumen within the tube is open to allow liquid to flow through the spout, and when the trigger is in the closed position, the lumen within the tube is closed to block liquid flow through the spout;wherein the trigger comprises a sealing edge that presses against a side of the tube and collapses the tube against a sealing surface of the cap body when the trigger is in the closed position, and the sealing edge moves away from the sealing surface of the cap body when the trigger moves toward the open position to allow the lumen with the tube to open;wherein the trigger further comprises a catch that engages with the cap body when the trigger is in the closed position to lock the trigger in the closed position, and the catch can be released from the cap body by a user to allow the trigger to move to the open position;wherein the trigger has a spring-like configuration; andwherein the trigger comprises a first arm and a second arm that are coupled at an inner end portion of the trigger, such that the first and second arms are biased apart from each other by the inner end portion. 2. The cap assembly of claim 1, wherein the tube extends in a generally axial direction through the passageway in the cap body and the trigger is slidable in directions generally perpendicular to the axial direction. 3. The cap assembly of claim 1, wherein the trigger comprises a passageway through which the tube extends, and the sealing edge is at one side of the passageway of the trigger. 4. The cap assembly of claim 1, wherein the cap body comprises a slot that receives the trigger, the slot intersecting the passageway through the cap through which the tube extends, such that the slot and the passageway in the cap body are generally transverse to each other. 5. The cap assembly of claim 1, wherein the first and second arms are elastically bent toward each other when the trigger moves toward the closed position, and the first and second arms resiliently separate apart from each other when the trigger moves toward the open position. 6. The cap assembly of claim 5, wherein the first arm includes the catch facing away from the second arm such that the catch is biased against the cap body. 7. The cap assembly of claim 6, wherein when the trigger is in the closed position, the first arm must be bent toward the second arm to release the catch from the cap body and allow the trigger to move toward the open position. 8. The cap assembly of claim 1, wherein the inner end portion of the trigger and the sealing edge of the trigger are positioned on opposite sides of the tube. 9. The cap assembly of claim 1, wherein the sealing surface of the cap body is offset axially from the sealing edge of the trigger, such that when the trigger is in the closed position, the tube is kinked out of axial alignment. 10. The cap assembly of claim 1, wherein the spout further comprises a flexible outer sheath coupled to an upper end of the tube such that the inner lumen extends through the tube and the outer sheath, the outer sheath being positioned on an upper side of the cap body, and the spout further comprises a rigid stem positioned within the outer sheath, such that the outer sheath and the stem form a valve that allows liquid flow from the tube, between the outer sheath and the stem, and out of the spout. 11. The cap assembly of claim 10, wherein the outer sheath comprises an inner annular surface that seals around an outer annular surface of the stem to prevent fluid flow through the spout, and wherein the inner annular surface of the outer sheath can be elastically deformed away from the outer annular surface of the stem to allow fluid flow out of the spout by increasing fluid pressure within the lumen or by pinching the outer sheath. 12. The cap assembly of claim 1, wherein the spout further comprises a mouthpiece coupled to the tube and positioned outside of the cap body, wherein the mouthpiece is rotatable relative to the cap body, and wherein rotating the mouthpiece relative to the cap body changes an angle at which the mouthpiece extends from the cap body. 13. The cap assembly of claim 12, wherein at one rotational position, the mouthpiece extends upwardly from the cap body in a direction generally aligned with a longitudinal axis of the tube, and at another rotational position, the mouthpiece extends from the cap body at an angle from the longitudinal axis of the tube. 14. A drink bottle comprising: an elastically squeezable fluid container having an upper opening; anda cap assembly removably coupled to the upper opening of the fluid container;wherein the cap assembly comprises a cap body, a spout having a flexible tube passing through the cap body for conducting fluid out of the fluid container, and a trigger configured to releasably close the tube to prevent fluid flow through the spout;wherein the trigger is configured to be pushed inwardly relative to the cap body from an open position to cause a sealing edge of the trigger to collapse the tube in a closed position, and such that a catch on the trigger engages with the cap body in the closed position to lock the trigger in the closed position until the catch is manually released;wherein the spout further comprises a mouthpiece valve positioned above the cap body and coupled to the tube, the mouthpiece valve comprising a flexible outer sheath and a rigid stem positioned within the outer sheath, such that the mouthpiece valve forms a seal between the outer sheath and the stem to prevent fluid flow through the spout, and such that the seal is openable to allow fluid to flow through the tube, between the outer sheath and the stem, and out of the spout when trigger is in the open position and the fluid container is squeezed; andwherein the trigger comprises a first arm and a second arm that are coupled at an inner end portion of the trigger, such that the first and second arms are biased apart from each other by the inner end portion and elastically bent toward each other by contact with the cap body, such that when the trigger is pushed toward the closed position the cap body causes the two arms to deflect toward each other, and the first and second arms resiliently separate apart from each other when the trigger moves toward the open position. 15. The drink bottle of claim 14, wherein the seal can also be opened by pinching the outer sheath below the seal. 16. The drink bottle of claim 14, further comprising a modular handle, wherein the fluid container and the modular handle comprise corresponding indexing features of locking features that prevent the handle from rotating relative to the fluid container. 17. The drink bottle of claim 14, wherein the fluid container has an upper portion having a generally circular cross-sectional shape and a lower portion having a generally D-shaped or kidney-shaped cross-sectional shape. 18. The drink bottle of claim 14, wherein the mouthpiece valve is rotatable relative to the cap body, and wherein rotating the mouthpiece valve relative to the cap body changes an angle at which the mouthpiece valve extends from the cap body, such that at one rotational position the mouthpiece valve extends upwardly from the cap body in a direction generally aligned with a longitudinal axis of the bottle, and at another rotational position the mouthpiece valve extends from the cap body at an angle from the longitudinal axis of the bottle.
