ABSTRACT:
An out-of-round indicator for golf balls utilizes an indicator module inserted into a golf ball sleeve or carton, with the module including a cup at its base into which the golf ball is dropped. The indicator includes a cantilevered arm extending from the base and spring loaded towards the surface of the golf ball, such that a surface of the arm contacts the surface of the golf ball, with the distal portion of the arm having a laterally extending tab or flag with differently colored spaced vertical markings. In one embodiment, a stationary vertically-extending support rises from a side of the base and has a vertical slot at its distal end overlying the tab, such that when the golf ball is rotated in the cup, the marking which appears through the slot indicates the out-of-roundness of the ball as the ball is rotated. The golf ball sleeve or box is provided with an aperture to permit rotation of the golf ball in the cup when the module is in the sleeve and when the golf ball is dropped into the cup. The sleeve is also provided with a transparent portion which overlies the slot in the support so that the out-of-roundness condition of the golf ball can be visually ascertained from outside the sleeve.
