ROLL ON TYPE FLUID APPLICATOR WITH SEALING MEANS ABSTRACT OF THE DISCLOSURE A roll-on type fluid applicator which has a ball type fitment or collar with a roll-on ball therein and a cap or closure therefor. The ball type fitment is formed of a plastic material and has a rim adjacent the mouth thereof with an inwardly extending rim lip to engage the ball and forming a sealing connection therewith. The cap is detachably secured to the container to cover the fitment. The cap has a top with a plurality of downwardly extending pressure applying flexible fingers formed inte- grally with the top and extending downwardly for engagement with the ball. The cap also has a flexible sealing mem- ber formed integrally with the cap and extending inwardly of the interior of the cap. The flexible sealing member is positioned in a plane lower than the plane of the down- wardly extending flexible fingers. The cap, when tightened with respect to the container, will cause the pressure applying fingers to bear against the normally exposed portion of the ball to urge the ball inwardly or down- wardly in the direction of the fitment so that it esta- blishes a seal tight contact with a lower sealing ring in the lower portion of the fitment to block the discharge of the fluid from the container. The flexible sealing member of the fitment engages the rim of the fitment to form a seal therewith. The cap sealing member and the lower sealing ring of the fitment will prevent the major portion of the ball, namely the portion extending above the lower sealing ring of the fitment, from drying up when in non-use position. The flexibility of the pressure applying fingers and the flexibility of the cap sealing member will com- pensate for the dimensional variability and fit between the fitment and the ball and the cap and fitment and yet provide effective sealing between the parts.
