Abstract
A dispensing cap with hinged flaps for opening and closing spoon and shake apertures in the cap end wall. The flaps, which are hinged away from the perimeter of the cap, include sealing plugs for the apertures. The plugs and apertures are formed by tooling elements on the same half of a mold to maintain very precise positioning of the plugs relative to the apertures. This precise positioning of the plugs and apertures allows them to be sized to produce a very light interference or touch fit that effectively stops moisture vapor transmission into the container and sifting of product out of the container to which the cap is fitted but, desirably, has little effect on flap opening and closing force. The sealing effectiveness of the plugs and apertures enables the cap to be used without a sealing liner for the mouth of the container.
