1. A closure mechanism for a container having two fluid channels, the closure mechanism comprising a cap
a delayed valve actuation mechanism comprising
an actuation plate configured to rotate about a central axis in a first direction in a range of 0 to 180 degrees, and to rotate about the central axis in a direction opposite the first direction in a range of 180 degrees to 0 degrees, the actuation plate comprising
a bottom surface,
an arced slot comprising an opening end and a closing end,
a first fluid opening and a second fluid opening,
a support plate comprising
a top surface,
a first fluid opening, a second fluid opening, an arced slot comprising an opening end and a closing end,
a valve plate configured to rotate about the central axis as the cap is moved in the first direction range of 0 to 90 degrees, and rotate about the central axis in a direction opposite the first direction as the cap is moved in a range of 90 degrees to 0 degrees, the valve plate comprising
a first fluid opening and a second fluid opening,
a top surface configured to seal against the bottom surface of the actuation plate,
a bottom surface configured to seal against the top surface of the support plate,
a first actuation post extending upward into the actuation plate arced slot,
the first actuation post forcing the valve plate to rotate in concert with the actuation plate when the first actuation post is in contact with the opening end or the closing end of the arced slot of the actuation plate, and
a second actuation post extending downward into the support plate arced slot, the second actuation post forcing the valve plate to rotate in concert with the second actuation plate when the actuation post is in contact with the opening end or the closing end of the arced slot in the support plate; and
a compressive structure configured to maintain a compressive force between the bottom surface of the actuation plate and the top surface of the valve plate, and between the bottom surface of the valve plate and the top surface of the support plate, such that
(a) when the valve plate and the valve actuation plate are oriented at 0 degrees, a first fluid path is formed between a first container fluid channel through the first fluid openings of the support plate, valve plate and actuation plate, and a second fluid path is formed between a second container fluid channel through the second fluid openings of the support plate, valve plate and actuation plate, and
(b) when the valve plate is oriented at 90 degrees, the portions of the valve plate seal the first and second fluid openings of the support plate.
