Disclosed are embodiments of bottle caps that comprise a rigid body configured to be secured to an opening of a bottle, a multi-position valve coupled to the body for regulating fluid flow through the cap, and a lid coupled to the body that can cover the valve. The cap can be adjustable between at least a closed position, a selectively open position, and a fully open position. In the closed position, the lid covers the multi-position valve and fluid flow through the multi-position valve is prevented. In the selectively open position, the lid is uncovered from the multi-position valve and the multi-position valve is operable to open to allow fluid flow when a flexible portion of the multi-position valve is squeezed by a user. In the fully open position, the lid is uncovered from the multi-position valve and fluid can flow freely through the multi-position valve.

1. A bottle cap comprising: a rigid body that is securable to an opening of a bottle;a multi-position valve coupled to the rigid body and operable to regulate fluid flow through the bottle cap; anda lid coupled to the rigid body;wherein the bottle cap is adjustable between at least a closed position, a selectively open position, and a fully open position, wherein: when the bottle cap is in the closed position, the lid covers the multi-position valve and fluid flow through the multi-position valve is prevented;when the bottle cap is in the selectively open position, the lid is uncovered from the multi-position valve, the multi-position valve opens to allow fluid flow through the bottle cap when a flexible portion of the multi-position valve is engaged by a user, and the multi-position valve remains closed to block fluid flow through the bottle cap when the flexible portion is not engaged by the user; andwhen the bottle cap is in the fully open position, the lid is uncovered from the multi-position valve and the multi-position valve remains open to allow fluid through the bottle cap whether or not the flexible portion is engaged by the user. 2. The bottle cap of claim 1, wherein when the bottle cap is in the selectively open position, the multi-position valve is operable as a bite valve such that the user can selectively open the multi-position valve to permit fluid flow through the bottle cap by biting on the flexible portion of the multi-position valve. 3. The bottle cap of claim 1, wherein the multi-position valve comprises a flexible tubular portion that is collapsed to prevent fluid flow through the tubular portion in the closed position, and open to allow fluid flow through the tubular portion in the selectively open position and in the fully open position. 4. The bottle cap of claim 1, wherein the multi-position valve is pivotably coupled to the rigid body of the bottle cap and the multi-position valve is pivotable between a folded down position when the bottle cap is in the closed position and an unfolded position when the bottle cap is in the selectively open position or the fully open position. 5. The bottle cap of claim 4, wherein when the multi-position valve is in the folded down position, a flexible tube portion of the multi-position valve is collapsed and prevents fluid flow through the multi-position valve. 6. The bottle cap of claim 5, wherein when the multi-position valve is in the folded down position, the flexible tube portion of the multi-position valve is collapsed due to compression between a first surface on the multi-position valve and a second surface on the body of the cap. 7. The bottle cap of claim 1, wherein the multi-position valve comprises a rigid valve base having a fluid passage therethrough, a rigid annular collar adjustably mounted around an outer surface of the valve base, a flexible sheath mounted on the collar, and a rigid stem mounted to the valve base, wherein the collar and the sheath are axially adjustable relative to the valve base and the stem to adjust the bottle cap between the selectively open position and the fully open position. 8. The bottle cap of claim 7, wherein when the bottle cap is in the selectively open position, a head of the stem seals against an inner surface of the sheath to block fluid flow from the fluid passage of the valve base through the sheath when the sheath is not engaged by the user, and an opening is formed between the head of the stem and the inner surface of the sheath when the sheath is squeezed by the user. 9. The bottle cap of claim 8, wherein the stem includes a narrow neck portion between the head of the stem and the valve base, and the opening is formed between the head of the stem and the inner surface of the sheath when the sheath is squeezed by the user around the neck portion of the stem. 10. The bottle cap of claim 7, wherein the valve base defines a fluid flow axis extending through the fluid passage of the valve base, and wherein the valve base includes a helical groove in an outer surface of the valve base and the collar includes an inwardly projecting guide pin that is engaged in the helical groove in the valve base, and the engagement between the guide pin and the groove causes the collar and the sheath to move axially relative to the valve base when the sheath and collar are rotated circumferentially relative to the valve base, such that the relative axial motion adjusts the bottle cap between the selectively open position and the fully open position. 11. The bottle cap of claim 10, wherein when the bottle cap is in the fully open position, a head of the stem is positioned within a portion of the sheath having an inner diameter that is greater than a diameter of the head of the stem, such that fluid is allowed to flow freely through the sheath around the head of the stem. 12. The bottle cap of claim 1, further comprising a slider that is slidable relative to the body between a first position wherein the slider pinches a flexible tube of the multi-position valve to prevent fluid flow therethrough and a second position wherein the slider does not pinch the flexible tube to allow fluid flow therethrough, and wherein a position of the lid relative to the body controls motion of the slider between the first and second positions. 13. The bottle cap of claim 12, wherein the lid is pivotable relative to the body about a pivot axis between a closed lid position and an open lid position, and wherein a pivotal position of the lid corresponds to a sliding position of the slider, such that the closed lid position of the lid corresponds to the first position of the slider and the open lid position of the lid corresponds to the second position of the slider. 14. The bottle cap of claim 13, wherein the lid includes a rounded surface that extends circumferentially around the pivot axis, and the rounded surface varies in radial distance from the pivot axis as a function of a circumferential position about the pivot axis, and wherein the slider includes a contact surface that engages with the rounded surface of the lid such that the position of the slider relative to the body is controlled by the radial distance from the pivot axis of the portion of the rounded surface that is in contact with the contact surface of the slider. 15. The bottle cap of claim 4, wherein the multi-position valve projects upwardly and forwardly from the body when the bottle cap is in the selectively open position and the fully open position, and the multi-position valve folds rearwardly relative to the body when the bottle cap is in the closed position. 16. The bottle cap of claim 4, wherein the multi-position valve projects upwardly and forwardly from the body when the bottle cap is in the selectively open and fully open positions, and the multi-position valve folds forwardly relative to the body in the closed position. 17. The bottle cap of claim 1, wherein the multi-position valve remains in a fixed orientation relative to the rigid body as the bottle cap is adjusted between the closed position and the selectively open position.
