Abstract
A roll-on liquid applicator having an applicator ball disposed within a dispensing chamber and a spring element with a valve head portion. The spring element effects a distally-directed force to press the valve head against the valve opening to maintain a sealing closure of the valve opening against flow of the liquid from the feed chamber into the dispensing chamber. The valve head has a ball support structure which extends distally through the valve opening to contact with the applicator ball so that when the ball is inwardly displaced by force applied thereto, the valve head moves axially inward from the closed-valve position to the open-valve position, thereby moving the valve head from the closed-valve position in contact with the valve opening toward the open-valve position which allows liquid from the feed chamber to enter the dispensing chamber.
