A roller-type storage container, dispenser and applicator includes a ball centered in a ball-retaining socket in a cap threadedly surmounting a container body. The cap is joined through an integral live hinge to a lid which is formed with an interior annular ring. Upon closure of the pivotally-hinged lid, the interior annular ring engages and bears inwardly against an outer upper wall section of the ball-retaining socket of the cap and urges the wall of the ball-retaining socket into positive, fluid-sealing engagement against the ball surface. Simultaneously, a vertically-directed force vector, generated during closure forces impressed by the lid upon the cap, bears upon the ball-retaining socket and forces the ball downwardly to seal against an annular, radially-inwardly-presented sealing ring integrally formed at a base of the ball-retaining socket, to seal the contents of the container therewithin.
