A linerless closure cap and fitment assembly configured for use with a container having a neck with an annular lip at its uppermost end defining a mouth. The closure cap and fitment assembly includes a fitment with a dispensing surface having a resealable pour spout and possibly sifting holes dimensioned to span the mouth of the container and a cap with a top panel, an annular skirt and threads for releasable engagement onto the neck of the container. The fitment includes a vertical fin along the sides of the pour spout to dam the product within the container, thereby stopping the product from sifting or "dusting" out of the closure during shipment in an upright or upside down position.
