A roll-on dispenser for a liquid deodorant product is of oval cross-section and has an elongated applicator ball (14). The applicator ball (14) is journalled for rotation on the dispenser body (10). The ball (14) is held in permanent engagement with an apertured seat which together with the ball (14) closes the top end of the product reservoir (11). Little or no product loss can therefore occur when the ball is not rotating. For dispensing product the surface of the ball is formed with hollow depressions (32) each capable of transferring a quantity surface as the ball rotates. Each depression (32) can be completely closed off by the seat so as not to provide a leakage path past the seat when the ball is stationary. <IMAGE> |
