Closure cap with flow restriction member

A closure cap in combination with a spout for a container, the spout defining a flow passage, the closure cap comprising:

• a rigid tubular base having an upper end and a lower end, the tubular base positionable about and sealingly engageable with the spout;
• a flexible cover extending over the upper end of the tubular base and being movable between a non-depressed position and a depressed position;
• and
• a flow restriction member having an annular wall forming an aperture and being positionable over and engageable with the spout, the flow restriction member detachably mounted to the tubular base such that the flow restriction member is in a spaced, coaxial relationship with the spout of the container when the tubular base is engaged with the spout of the spout fitment and when the flexible cover is in the non-depressed position and such that the flow restriction member is detached from the tubular base and positioned on and engaged with the spout of the spout fitment when the flexible cover is moved to the depressed position.
