2. The closure of claim 1 , wherein the lock tab includes a body plate that is coupled to the flip-top cap, a first protuberance coupled to a first circumferential side of the body plate, and a second protuberance coupled to a second circumferential side of the body plate, the first protuberance arranged to engage the first retainer rail in the locked position and the second protuberance arranged to engage the second retainer rail in the locked position.

4. The closure of claim 3 , wherein the first and second retainer rails each further include an inner surface spaced apart from the inner side wall to provide first and second unlocking passageways therebetween that receive the corresponding one of the first and second protuberances after the lock tab is deformed and as the flip-top cap is moved from the closed position toward the opened position.

5. The closure of claim 1 , wherein the central port and the upper disk are formed to include a first passageway that extends along the central axis and the lower disk is formed to include a second passageway that extends along a second axis that is transverse to the central axis.

6. The closure of claim 5 , wherein the upper disk has an outer diameter that is sized to locate an outer edge of the upper disk between the top wall of the lid and an upper surface of a filler neck of a container, and the lower disk has an outer diameter that is less than the outer diameter of the upper disk and to locate an outer edge of the lower disk in spaced-apart relation to the filler neck of the container.

7. The closure of claim 1 , further comprising an anti-suction feature coupled to the top wall of the lid and configured to maintain spacing between an upper surface of the top wall and a mouth of a person placed on the lid around the opening to minimize formation of a complete seal between the mouth and the lid so that the mount cannot establish sufficient suction to remove fluid through the opening, wherein the anti-suction feature includes a plurality of ribs coupled to the upper surface of the top wall and that extend outwardly away from the opening along the upper surface.

8. A closure comprising a lid including a top wall formed to include a central opening, and a side wall that extends downwardly from the top wall, the side wall having an inner side wall that extends circumferentially about a central axis, an outer side wall spaced radially from the inner side wall and that extends only part-way around the central axis, and a rim connector that interconnects the inner side wall with the outer side wall,

a flip-top cap mounted to the lid for pivotable movement about a cap pivot axis between a closed position, in which the flip-top cap covers the central opening formed in the lid, and an opened position, in which the flip-top cap is spaced apart from the top wall of the lid to expose the central opening, and

a valve including a central port sized and arranged to extend through the central aperture formed in the top wall, an upper disk coupled to the central port and arranged against an inner surface of the top wall, and a lower disk coupled to a lower surface of the upper disk,

wherein the central port and the upper disk are formed to include a first passageway that extends along the central axis and the lower disk is formed to include a second passageway that extends along a second axis that is transverse to the central axis.

9. The closure of claim 8 , wherein the second axis is perpendicular to the central axis.

10. The closure of claim 9 , wherein the second passageway extends between a first aperture and a second aperture and the first and second apertures are sized to block fluid flow through the second passageway in the absence of a vacuum force above a predetermined threshold.

11. The closure of claim 8 , wherein the upper disk has an outer diameter that is sized to locate an outer edge of the upper disk between the top wall of the lid and an upper surface of a filler neck of a container, and the lower disk has an outer diameter that is less than the outer diameter of the upper disk to locate an outer edge of the lower disk in spaced-apart relation to the filler neck of the container.

12. The closure of claim 8 , further comprising an anti-suction feature coupled to the top wall of the lid and configured to maintain spacing between an upper surface of the top wall and a mouth of a person placed on the lid around the opening to minimize formation of a complete seal between the mouth and the lid so that the mount cannot establish sufficient suction to remove fluid through the opening, wherein the anti-suction feature includes a plurality of ribs coupled to the upper surface of the top wall and that extend outwardly away from the opening along the upper surface.

13. A closure comprising

a lid including a top wall formed to include an opening and a side wall that extends downwardly from the top wall and extends circumferentially about a central axis,

a flip-top cap mounted to the lid for pivotable movement about a cap pivot axis relative to the lid between a closed position and an opened position, and

an anti-suction feature coupled to the top wall of the lid and configured to maintain spacing between an upper surface of the top wall and a mouth of a person placed on the lid around the opening to minimize formation of a complete seal between the mouth and the lid so that the person cannot establish sufficient suction to remove fluid through the opening.

14. The closure of claim 13 , wherein the anti-suction feature includes a plurality of ribs coupled to the upper surface of the top wall and that extend outwardly away from the opening along the upper surface, and each of the ribs included in the plurality of ribs includes an inner portion that abuts the opening and an outer portion that extends outwardly away from the inner portion.

15. The closure of claim 14 , wherein the inner portion has a greater height from the upper surface of the top wall compared to the outer portion.

16. The closure of claim 15 , wherein the outer portion tapers as it extends outwardly such that a height of the outer portion from the upper surface of the top wall decreases and a width of each rib increases as each rib extends outwardly from the opening.

17. The closure of claim 14 , further comprising a valve including a central port sized and arranged to extend through the central opening formed in the top wall, an upper disk coupled to the central port and arranged against an inner surface of the top wall, and a lower disk coupled to a lower surface of the upper disk, the central port and the upper disk being formed to include a first passageway that extends along the central axis and the lower disk being formed to include a second passageway that extends along a second axis that is transverse to the central reference axis.

18. The closure of claim 13 , further comprising a child-resistant closure-release mechanism including a lock tab coupled to the flip-top cap and first and second retainer rails coupled to the outer side wall of the lid.

19. The closure of claim 18 , wherein the lock tab is deformable relative to the lid from a locked position, in which the lock tab engages the first and second retainer rails to block the flip-top cap from pivoting about the cap pivot axis to the opened position, and an unlocked position, in which at least a portion of the lock tab is deformed inwardly toward the inner side wall of the lid to disengage the lock tab from the first and second retainer rails so that the lock tab is movable with the flip-top cap between the inner and outer side walls of the lid as the flip-top cap is pivoted about the cap pivot axis from the closed position to the opened position.
